Correlation and Path Analysis Studies in Groundnut under Different Dates of Sowing | Chapter 11 | Research Advances and Challenges in Agricultural Sciences Vol. 5

Research on the genotypic and phenotypic associations among agricultural crop traits can be used to design, evaluate, and develop selection criteria for desirable traits. Yield is a complex quantitative trait largely influenced by the environment. Direct selection for grain yield is less efficient in improving groundnut productivity. The selection efficiency can be enhanced by exploiting the relationship between yield and its related traits. In the present study strong positive association was noticed between pod yield per plant and kernel yield per plant, oil yield per plant and significant and negative association with late leaf spot severity and rust incidence irrespective of the environments. Pod yield was also correlated with 100-kernel weight, plant height and oil content in environment III. The magnitude and direct association of pod yield with other characters varied from environment to environment. Inter correlation estimates for yield components revealed that plant height, 100-kernel weight, kernel yield per plant, oil yield per plant, late leaf spot severity, number of matured pods per plant, harvest index and plant height were significantly associated with one another and also with pod yield per plant which indicated that these characters were important components for improvement of pod yield in groundnut. This indicated that selection of genotypes based on oil yield per plant and kernel yield per plant is advantageous than the other characters. The direct effect of kernel yield per plant in all the three environments followed by shelling percentage, rust incidence, oil yield per plant, number of branches per plant in environment I and plant height in environment I and III. The direct effect of other characters fluctuated between negative and positive values indicating the influence of environment on these traits.

Effect of Sulphur and Boron on the Growth, Yield and Quality of Hybrid Sunflower | Chapter 9| Research Advances and Challenges in Agricultural Sciences Vol. 4

 India is the largest producer of oilseeds in the world in terms of output. Sulphur deficiency is observed primarily due to high crop yield and therefore higher rate of S removal by crops, and lesser use of S-containing fertilizers. As with Sulphur, Boron (B) is also one of the micronutrients required for normal growth and development of many crops. Sunflower is one of the most sensitive crops to B deficiency. This experimentation was conducted to enhance growth and yield, quality, nutrient uptake, post-harvest soil nutrient status and Sulphur use efficiency of sunflower.

The Field investigations were conducted in two locations viz., at Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalai Nagar, Tamil Nadu during March – June 2013 and at farmers’ field at Ko-Chathiram village, Kurinjipadi block, Cuddalore district, Tamil Nadu during July- October 2013 to study the effect of different levels of sulphur and boron on growth, yield attributes and yield of hybrid sunflower cv. Sunbred. The treatment consisted of Sulphur with five levels (0, 15, 30, 45, 60 kg S ha-1) and three levels of boron (0, 0.5, 1.0 kg B ha-1). Totally fifteen treatments were tested and were laid out in the factorial concept of randomized block design with three replications.

The results revealed that growth, yield attributes and yield, quality, nutrient uptake, post-harvest soil nutrient status and sulphur use efficiency were significantly influenced by various S levels in the B levels. Among the different levels of sulphur tried, application of 60 kg S ha-1 with B @ 1 kg ha-1 significantly recorded maximum growth, yield attributes and yield, quality, nutrient uptake, post-harvest soil nutrient status and sulphur use efficiency of hybrid sunflower while 0 kg S ha-1 with B @ 1 kg ha-1 registered minimum values for growth and yield of sunflower. Boron levels significantly influenced the seed and stalk yield in both crops. Among the treatment combinations tried, 60 kg S ha-1 with B @ 1 kg ha-1 has a spectacular effect on growth and yield attributes, ultimately leading to maximum seed yield (2573.25 and 2673.84 kg ha-1) in both crops. The lowest values of growth and yield attributes and yield were recorded by 0 kg S ha-1 with B @ 1 kg ha-1. The oil content of sunflower seeds was significantly influenced by Sulphur application.

Effect of NPK Fertilizers, FYM and Vermicompost on Growth and Yield Attributes of Okra (Abelmoschus esculentus L.) var. Devika | Chapter 3 | Research Advances and Challenges in Agricultural Sciences Vol. 1

 This member highlights the belongings of NPK fertilizers, FYM and Vermicompost on growth and yield ascribed of okra. A field experiment was conducted in the period 2022 during the Kharif season at research farm of Area of Soil Science and Land Allure, Sam Higginbottom University of Farming, Technology and Sciences Prayagraj (Allahabad) 211007 U.P., India. The design used for statistical study was carried out accompanying randomized block design having three levels of NPK @ 0, 50 and 100% ha-1, three levels of FYM @ 0, 50 and 100% ha-1 and three levels of Vermicompost @ 0, 50 and 100% ha-1 individually. The soil experimental region was sandy earth in texture. The design was spent money in randomized block design with three levels of NPK (0, 50, & 100%), three levels of FYM and three levels of Vermicompost (0, 50, & 100%) individually. The results acquired with situation T9-[120:60:50 Kg NPK + 25 t FYM + 6 t Vermicompost] showed best  plant height, number of arms plant-1, number of leaves plants-1, number of fruits plant-1, total product per plant. Among the situations, Organic manures in addition to its combination with complete NPK considerably increase in development and total yield attributes of okra. Opposite to all other situations, combination of NPK, FYM and Vermicompost at 100% each individually gave ultimate significant affect okra growth. The study disclosed that the application of NPK FYM and Vermicompost in situation was found best in growing growth and yield of okra.

Evaluation of Agronomic Genotypes of Maize (Zea mays L.) under Agro-climatic Conditions during Kharif Season-of in Prayagraj, Uttar Pradesh, India | Chapter 9 | Emerging Issues in Agricultural Sciences Vol. 6

 This branch find out best choice Genotype among the maize hybrids, a field old periment was conducted all along the kharif season of 2022 at the experimental field of the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology   and Sciences, Prayagraj, Uttar Pradesh, India. All maize hybrids follow alike pattern of  development, even though specific occasion and interval betwixt stages and total number of leaves developed grant permission vary between hybrids, seasons, period of planting and location. The more protracted maturity mixture usually had piece yield advantage over former maturity mixture when planting at early May, but the former maturity hybrid frequently showed a better yield than longer adulthood hybrid when setting was delayed. The experiment was planned in a randomized complete block design which amounted to ten maize genotypes as treatments. The situations were replicated three times. The meaningful difference ingrain yield and other not urban traits between various hybrids was on account of the diverse environment from which the hybrids were developed. The result of the study signifies that among various maize Genotypes, M-410 produced considerably higher plant climax (218.35 cm), number of leaves per plant (15.60), dry weight per plant (152.24g), raises animals length (19.26 cm), number of rows per outdo a performance(14.85), number of grains per row ( 37.03), seed yield (9.54 t/ha) and stover yield (21.62 t/ha).. It was found more creative, when compared to possible choice under agroclimatic conditions of Prayagraj, Uttar Pradesh. Since the future research is urged to be transported before recommending M - 410 genotype to rancher.
