Influence of Planting Dates on NPK Composition in Soybean Cultivars: A Comparative Analysis | Chapter 10 | Current Research Progress in Agricultural Sciences Vol. 2

 

The present study explores the influence of planting dates on NPK composition in soybean cultivars, conducting a comparative analysis across various planting schedules. Legumes provide a protein-rich source of food which is an essential part of the diets of people inhabiting in the tropics.. Growth, development, and production of Soybean Glycine max (L.) are negatively impacted by delayed planting dates and poor environmental circumstances. The nitrogen, phosphorus and potassium accumulation at harvest and nitrogen, phosphorus and potassium content in seed impacted by changes in photoperiod, temperature, and precipitation with delayed planting. Extremely high temperatures and drought stress are examples of environmental variables that negatively impact plant development and productivity and are frequently linked to delayed planting. The finding reveals significant variation in the NPK composition contingent on planting dates, underscoring the importance of optimal timing for planting. This study also provides valuable insights for farmers and agronomists seeking to optimize soybean production through strategic planting schedules.

Management of Nutrients in Dill Seed (Anethum graveolens L.) | Chapter 5 | Current Research Progress in Agricultural Sciences Vol. 3

The present study explores the management of Nutrients in Dill Seed (Anethum graveolens L.). An adequate supply of nitrogen is associated with vigorous vegetative growth and dark green colour. Phosphorus influences the vigour of plants, and root growth and enhances maturity. The investigation was carried out during the rabi season of 2016-17, 2017-18, and 2018-19 at College Farm, Navsari Agricultural University, Bharuch (Gujarat) to determine the requirement of nitrogen and phosphorus for dill seed for achieving maximum seed yield. Three different levels of nitrogen (20, 40, and 60 kg/ha) and phosphorus (00, 20, and 30 kg P2O5/ha) in different combinations were distributed in the plots. The nitrogen and phosphorus were applied at the time of sowing. The different dose of nitrogen and phosphorus was applied in the form of urea and SSP as per the treatment in each plot. The results indicated that application of nitrogen at 60 kg/ha significantly increased plant height, branches/plant, number of umbels/plants, seeds/umbel, seed yield (1451 kg/ha) and straw yield (6008 kg/ha), net returns (Rs. 68299/ha) and B:C ratio (2.4), while, significantly higher grain yield (1407 kg/ha) and straw yield (5977 kg/ha), net returns (Rs. 66289/ha) and B:C ratio (2.3) compared with other treatment. It also significantly increased the content and uptake of nitrogen and phosphorus at 60 kg N/ha and 30 kg P2O5/ha in seed and straw and also improved the nutrient status of the soil. Interaction effects between 60 kg N/ha and 30 kg P2O5/ha were significantly higher for umbels/plant and seed yield. Plant height in dill seed did not differ significantly due to different phosphorus levels. The number of branches per plant of dill seed did not differ significantly due to different phosphorus levels. The positive influence of P application on a number of branches/plants may be due to the increased availability of nitrogen and potassium which resulted in better plant growth.

Combined Effect of Trichoderma viride with Other Phosphate Solubilizing Microorganisms on Soil Nutrient Availability and Uptake by Rice Plant | chapter 4 | Scientific Research, New Technologies and Applications Vol. 4

The present study highlights the combined effect of Trichoderma viride (T.V) with other Phosphate Solubilizing Microorganisms (PSM) on soil nutrient availability and uptake by Rice plants. T.V is widely used in the field of Soil science for its various contribution to agriculture. It makes soil nutrients available and therefore in this research, utilization of T.V is done along with other PSM to solubilize phosphorus(P). PSMs are ubiquitous, whose number varies from soil to soil and help in the mineralization of organic P in the soil. The present work was conducted under lower Gangetic alluvial at the Agricultural Experimental Station of Calcutta University, Baruipur, 24 Parganas (South), West Bengal in a Rice plant. The experiment was carried out with six treatments(T) replicated four times, T1@Trichoderma viride (T.V), T2@ Azotobacter chroococcum (A.C)+ Trichoderma viride (T.V), T3@ Pseudomonas striata (P.S) + Trichoderma viride (T.V), T4@Azotobacter chroococcum (A.C) + Pseudomonas striata (P.S)+ Trichoderma viride (T.V), T5@ Azotobacter chroococcum (A.C) and T6@Azotobacter chroococcum (A.C) + Pseudomonas striata (P.S). Out of the six treatments, T3 which received T.V and P.S showed the highest Carbon(c), P and Potassium(K) content and T6 showed the highest nitrogen(N) content in the soil. P availability is increased with the application of T.V and the combination of T.V with other PSM shows even higher solubilization of P in the soil.

Benefits of Duckweeds for Phytoremediation | Chapter 8 | Research Advances in Environment, Geography and Earth Science Vol. 1

Aquatic plants, commonly known as duckweeds, represent a group of 36 species in the family Lemnaceae. Duckweeds are often regarded as detrimental to the environment because of their ability to quickly populate and cover the water surfaces due to their rapid vegetative propagation. However, their global distribution, tolerance to ammonia, heavy metals, other chemical pollutants, and environmental stresses make duckweed a favorite species for bioremediation of agricultural, municipal, and industrial wastewater. In course of their fast growth and biomass accumulation, duckweeds efficiently assimilate nitrogen- and phosphate-containing water pollutants, playing an important role in restorative ecology of water reservoirs. Moreover, compared to other species, duckweed species and ecotypes are highly adaptive to a variety of environmental contaminants. In summary, duckweeds are a powerful tool for bioremediation that can reduce anthropogenic pollution in aquatic ecosystems and prevent water eutrophication in a simple, inexpensive ecologically friendly way. Here, we reviewed the potential for using duckweeds in remediation of major water pollutants: mineral nitrogen and phosphorus, various organic chemicals, and heavy metals.

Physiological Response of Nitrogen Use Efficiency and Yield Attributes in Rice (Oryza sativa L.) Genotypes under Different Nitrogen Levels | Chapter 4 | Research Highlights in Science and Technology Vol. 6

 This division is useful to screen most N adept genotypes which maybe  strongly submitted to rice growers to improve crop yield irrespective of use of extreme dose of N fertilizers. The unoriginal farming considerably depending on synthetic fertilizer recommendation has been double-put paint or finish on; yield increase but environmental concerns to a degree soil degradation, organic diversity. A Field experiment was conducted at PJTSAU, Hyderabad, Telanagana, India all along 2011-12 to evaluate the effectiveness of varying nitrogen (N) manure rates on growth and yield limits, along with NUE (Nitrogen Use Efficiency) accompanying two N levels 60 and 120 kg N ha-1 as main treatments and twenty six edible grain genotypes as sub situations. N nutrition influences the content of photosynthetic pigments, combining of the enzymes taking part in the carbon decline,   formation of the sheath system of chloroplasts, etc. Photosynthetic rate raised from maximum tillering (18.41 m mol CO2 m-2 s-1) to flowering stage (22.24 m mol CO2 m-2 s-1) and written a decrease thereafter towards adulthood stage (13.23 m mol CO2 m-2 s-1). Application of appropriate level of N fertilization is a main objective to increase NUE by rice assortments. Among  the genotypes, MTU-1001 recorded the maximum seed yield of 5021 kg ha-1 even under application of 60 kg N ha-1 with maximum NUE in 60 kg N ha-1 (83.68) and minimum in 120 kg N ha-1 (45.53). NUE acted not increase linearly with the amount of N use and higher N levels presented significantly lower NUE principles. N contributes to hydrogen accumulation in culms and leaf sheaths all the while the pre-heading stage and basic during the ripening stage of edible grain. Maximum yield can be attributed to maximum SCMR (SPAD Chlorophyll rhythm reading) principles, more photosynthetic rate, more tillers and panicles, more number of grains hill-1, maximum suffused grain allotment and minimum spikelet sterility.

A Critical Review of Acid Rain: Causes, Effects, and Mitigation Measures | Chapter 2 | Novel Perspectives of Geography, Environment and Earth Sciences Vol. 6

 The astringency of rainwater has currently been revealed as a bigger environmental hazard to ecosystems and human health about the world. Therefore, it is very main to know what causes acid rain, allure effects, and what maybe done about it. This review is based on open-approach papers accompanying "acid rain" as a keyword and the situation of air pollution around the world. Typically, air pollution appears in the form of teeny bits of dry material, snowstorm, and fog that land on Earth. Acid rain commonly has a pH betwixt 4.2 and 4.4, whereas usual rain has a pH of 5.6. The production of electricity, the custom of vehicles, land and industrial activities, etc., all influence wet and dry deposition. Acid rain has belongings on aquatic environments, mammals, plants, soil, global preparing, vegetation cover, monuments, houses, and health. The verdicts of this research showed that optimizing the use of nonrenewable fuel sources, transitioning to renewable energy beginnings, limiting the use of fertilizers and pesticides, protecting energy, restoring the atmosphere, lowering use levels, convincing others, experiencing people, and following rules are sustainable ways of ruling acid rain. In addition, cooperations between the scientific and tactics communities maybe considered as a useful tool. Finally, the issues of acid rain and air contamination should be among the general big projects that demand everyone to reach the Sustainable Development Goals.

Species Diversity and Mud Puddling Activity of Butterflies in Madurai, Tamilnadu, India | Chapter 9 | Research Aspects in Biological Science Vol. 5

One of nature's most amazing species, butterflies play a crucial role in the ecology. Building construction replaces or reduces the butterflies' native habitat in the midst of urbanisation, which causes a sharp drop in butterfly variety, a sign of poor habitat quality. Puddling is a fascinating habit practised by butterflies in which they consume salts and minerals from mud puddles, dung, and carrion. Lepidopterans' dietary and reproductive state are impacted by the mud-puddle activity. The purpose of this study is to comprehend the species variety and richness as well as the mud-pumping behaviour of butterflies in the chosen Madurai, then examine the sample of soil for different minerals and salts to comprehend the significance of mud puddling in butterfly reproductive behaviour. Using the transect method, a butterfly survey was conducted in the Alagarkovil hills and on the campus of Lady Doak College from July 2017 to January 2018 on sunny days between 0800 and 1600 hours, three times per week. Six families included a total of 166 species that were recorded throughout the study period, with 49 species belonging to the leading Nymphalidae family. Of the six families, mud puddling was most frequently observed in the Lycaenidae, Nymphalidae, and Pieridae families. It was discovered that mud-puddle activity predominated in areas with lots of puddles. The soil study of the mud puddling sites revealed the presence of macro elements like phosphorus, nitrogen, and carbon as well as metal ions like manganese, iron, and copper as well as salts like sodium and potassium. It was discovered that the soil's alkaline pH favoured the puddling activity. At both research sites, host plants for 21 different plant species were discovered. Despite being an urbanised area, the Lady Doak College location is home to a wide variety of butterflies thanks to the quantity of appropriate habitat. Restoration of mud puddling places could improve the biodiversity index of butterflies in urbanised cities under conservation techniques.

Study on the Influence of Topography and Management Practices on Nitrogen Content of Soils Formed in Biotite-Granite Parent Material on the Jos Plateau, Nigeria | Chapter 07 | Recent Progress in Plant and Soil Research Vol. 5

 The purpose of this research is to examine the nitrogen content of soils produced on biotite-granite parent materials and to suggest management strategies that will ensure the nutrient's availability for long-term crop development. Nitrogen is an important macronutrient for crop growth and output. Soil fertility is one of the key restrictions to long-term crop productivity on the Jos Plateau. Soil fertility is determined by the availability of nitrogen and other important plant nutrients in the soil. A variety of factors, including drainage, texture, and slope steepness, influence nitrogen levels in soils. This research focused on biotite-granite, one of the most important parent materials in the Jos Plateau, taking into account geography and farmer management techniques. The results revealed that the soils had a low nitrogen concentration. The range of surface soils was 0.021-0.140 percent, with a mean of 0.065 percent. For the upper foot slope, middle foot slope, lower foot slope, and depression, the slope facets had means of 0.058 percent, 0.042 percent, 0.069 percent, and 0.103 percent, respectively. Organic matter was substantially linked (r =0.694) with the increased nitrogen concentration in the depression. The profile pit results revealed that soils in the upper foot slope and depression had greater surface contents (0.105 percent and 0.140 percent, respectively), while those in the intermediate foot slope had the lowest. At the surface, the profile pits with and without burnt municipal garbage had 0.150 percent and 0.090 percent, respectively. The T-test resulted in a value of 0.001 for nitrogen and 0.01 to 0.001 for other soil characteristics, showing that the two treatments had significant differences in their means. Crop rotation, cover crop planting, and mixed farming were suggested as management strategies for increasing nitrogen concentration in soils.

Analysis of Soil Properties of Ponds in Sabang Block Areas, West Bengal, India | Chapter 17 | New Visions in Biological Science Vol.9

 The study's goal was to assess the routine application of a commercially available and naturally occurring method for improving pond soil quality. So, in the year of the studies, nitrogen, phosphorus, and potassium were not detrimental to the carps' growth. Bacteria can be found in a variety of environments, including fresh water, soil, air, and seawater. Bacteria have different personalities based on their surroundings. As a result, periphyton bacteria in different zones have diverse characteristics. However, the study focused on soil analysis in Sabang block regions' fresh water ponds. The investigation lasted roughly a year in the Sabang block areas. In a bucket, soil was collected. This soil was gathered from five ponds in the Sabang block (Ghat pond, Dhara pond, Majari pond, Nandan pond, and Masanta pond). The ponds were divided into two categories: control and experimental. This pond was stocked with semi-dried cow dung. We used a variety of techniques in this experiment. The nitrogen, available phosphorus, and available potassium levels in the pond bottom soil were measured using AOAC standard procedures (1980). However, after treatment, the nitrogen level in all of the experimental ponds increased dramatically. When it comes to enhancing pond productivity, phosphorus is crucial. Potassium isn't a limiting element, and it's not necessary to boost output. The generation of free hygienic fish in ponds is the future scope.

Study on Assessment of Silicon and Nitrogen Fertilization on Plant and Soil Nutrition and Rice Yield Grown in Typic Ustifluvent Soil | Chapter 2 | Current Topics in Agricultural Sciences Vol. 3

 The goal of this study is to see how silicon and nitrogen treatment affects the chemical nutrition of plants and soil in Typic Ustifluvent soil.

Introduction: Nitrogen is an essential nutrient for plants, as it is required for photosynthesis, growth and development, rice yield, quality, and biomass. Silicon interacts well with other applied nutrients, improving their agronomic performance and yield response efficiency.

Factorial RBD was used in this study.

Study Location and Duration: Farmers in Kuttalam Block, Mayiladuthurai district, participated in field trials. For two seasons, the experiment was carried out.

Field tests were carried out in farmers' fields during the kuruvai and samba seasons. The treatments include silicon levels of 0, 50, 100, and 150 kg ha-1, as well as nitrogen levels of 0, 50, 100, and 150 kg ha-1, using rice vars. ADT43 and CR1009 as test crops. At harvest, the grain and straw yields were recorded. The nutritional content of grain and straw samples was determined, and the associated uptake was computed. The nutritional level of soil samples was determined at various physiological stages.

The results showed that graded doses of nitrogen and silicon applied alone or in combination resulted in a considerable increase in rice production when compared to the control. With 150 kg N / ha + 150 kg Si / ha, rice yields peaked (5600, 6786 kg ha-1) and straw yields peaked (6811, 8031 kg ha-1). However, 150 kg N / ha + 100 kg Si / ha and 100 kg N / ha + 150 kg Si / ha were equal. The rate of absorption increased as nitrogen and silicon levels increased. With 150 kg N / ha + 150 kg Si / ha, the maximum nutrient absorption was reported. It was similar to 150 kg of nitrogen per hectare and 100 kg of silicon per hectare. With higher N and Si levels, available nitrogen, phosphorus, potassium, and silicon increased. When nitrogen and silicon were sprayed at 150 kg/ha, the greatest available N, P, K, and Si were obtained.

Conclusion: For maximum yield of rice grown in low nitrogen and silicon soils, a combined application of 150 kg N/ha and 150 kg Si/ha is advised.

Investigating the Impact of Nitrogen and Seed Rates on Morpho-physiological Responses in Dual Purpose Wheat (Triticum aestivum L.) | Chapter 6 | Cutting-edge Research in Agricultural Sciences Vol. 4

 Growing two-purpose crops together, i.e. both grains and fodder, may be a good choice to reduce the pressure of growing alarming human populations. Wheat could be a better choice to alleviate the scarcity of both grains and fodder. In this direction, several works were carried out considering wheat, but the production was a constraint. Changes in fertiliser concentrations and seed rate are very important for different agronomic methods that affect yield. Nitrogen is one of the major fertiliser components that plays a crucial role in the growth of crops, including photosynthesis, protein synthesis, synthesis of nucleic acids, etc. The seed rate is directly linked to the expansion of the canopy and the interception of solar radiation, thus significantly affecting the use of environmental resources by altering the relative importance of intra- and interplant competition for light, water and nutrients during crop production and thus affecting the yield of wheat. In order to obtain information on the impact of seed rates and nitrogen levels on the forage and grain yield of dual-purpose wheat genotypes for enhanced productivity, this study was carried out with a view to the importance of the issue. Rising dual-purpose wheat is becoming increasingly important. For improved efficiency, parameters discussed in the manuscript may be taken into consideration. In order to serve both dual purposes, deep physiological and biochemical insights are needed to understand the factors that regulate both vegetative growth and grain production in wheat.

Breeding Perspectives and Dynamics of Rice (Oryza sativa) Improvement for Enhanced Nitrogen and Phosphorous Adaptation in Relation to Market Demand | Chapter 8 | Recent Advances in Science and Technology Research Vol.3

Rice is a very important crop feeding half of the global population. Its gaining high importance due to
high nutritive value, its short growth duration and high incomes per given land area than any other
cereal crop. Despite this, its production is facing challenges such as diseases and pests, degraded
soil, need for high grain quality, population growth, high input costs, climate change and variability
threats and plateauing yields. There is urgent need to come up with robust and innovative ways on
how to sustain and increase rice yield to feed the ever expanding population, and this will largely
involve increased yields per unit area, rather than horizontal expansion of new areas. More
importantly, the reproductive soil resource is under threat and thus this increased productivity must
enhance the conservation of the productive land resource base for sustainability especially in relation
to Nitrogen and Phosphorous nutrient elements. There is also need for deliberate efforts to diversify
