Examining Germination Potential, Seed Invigoration and Yield Growth of Lentil (Lens culinaris Medikus) through Seed Priming under Different Seeding Rates | Chapter 2 | Research Advances and Challenges in Agricultural Sciences Vol. 7

Lentil (Lens culinaris, Medikus) is an important food legume cultivated in rainfed areas in many countries including India. Field experiment to investigate the germination potential, seedling vigour and yield of lentil (Lens culinaris, Medik.) var ‘PL-4’ against three seed rates with hydro-primed, osmo-primed, sprouted seeds and unprimed seeds under tilled soil situation was conducted during rabi seasons of 2008-09 and 2009-10. The treatment was laid out under split-plot design using hydro-primed, osmo-primed with 1% KH2PO4, sprouted and unprimed seeds in the main plot and three seeding rates of 40, 50 and 60 kg/ha in the sub-plot. Yield attributes were recorded at harvest. Data were analyzed by OPSTAT software with split plot design, and priming methods in the main and seed rates in the sub-plots.
 
The result revealed that the highest germination rate was reflected with hydropriming which was significantly superior to other priming methods. The hydro-primed seeds significantly increased the percent germination (96.13%), nodules/plant (11.05), pods/plant (43.27) and seeds/ pod (1.91) as compared to rest of the priming methods but sprouted seed indicated better results statistically at par with hydro and osmo-priming in respect of root length (18.63 cm) and shoot length (28.63 cm), seedling vigor (4.35). Branches/plant (13.12) and test weight (2.11 g) showed insignificantly higher values in osmo-priming. The highest yield was achieved with sprouted seed (844.90 kg/ha) which was statistically at par with the rest of the treatments except unprimed seed. All the seed rates indicated no significant differences among them in respect of germination %, seedling vigor and other growth parameters, seeds/ plant and test weight except nodule count, branches/ plant, pods/plant and grim yield in which medium seed rate (50 kg/ha) was superior over rest of the seed rates. Interaction effect indicated that, sprouted seeds with medium seed rate (50 kg/ha) resulted in a significantly higher yield (856.27 kg/ha). A higher seed rate resulted in a significant increase in yield for hydro-primed or osmo-primed (KH2PO4) seeds. Sprouted seed and all priming agents indicated better yield than unprimed seeds while medium seed rates gave higher grain yield over lower and higher seed rates. Sprouted seeds with 50 kg/ha seed rate were optimum in rainfed lentil cultivation under conventional tilled soil conditions.

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.
