    Abstract: Field experiment was carried out during kharif  2020 and 2021 at wetland farm of S. V. agricultural College, Tirupati, Andhra Pradesh. The experiment was laid out in a split plot design with three replications. The treatments consisted of three main plots viz., 100 % RDF (N1), 125 % RDF (N2) and 150 % RDF (N3) and five sub plots viz., Pre emergence (PE) application of pyrazosulfuron-ethyl 25 g ha-1 fb penoxsulam + cyhalofop-p-butyl 125 g ha-1 at 20 DAS (W1), Pre emergence (PE) application of pyrazosulfuron-ethyl 25 g ha-1 fb florpyrauxifenbenzyl + cyhalofop-p-butyl 150 g ha-1 at 20 DAS (W2), Pre emergence (PE) application of pyrazosulfuron-ethyl 25 g ha-1 fb bispyribac-sodium 20 g  ha-1 at 20 DAS (W3), hand weeding twice at 20 and 40 DAS (W4) and unweeded check (W5). Nutrient levels and weed management practices significantly influenced the growth parameters viz., plant height, number of tillers m-2 and dry matter production and yield attributes viz., number of panicles m-2, total number of grains panicle-1 and number of filled grains panicle-1 of direct seeded rice during both the years of investigation as well as in pooled mean. Interaction effect due to nutrient levels and weed management practices on growth parameters and yield attributes was found to be significant during both the years of study and in the pooled mean.

    Abstract: Soil moisture deficit is the major constraint for sesame crop production during its main rainfed and summer cultivation seasons. In summer cultivation, the crop frequently gets exposed to soil moisture deficit at various crop growth stages. Therefore, it is essential to identify the traits along with promising genotypes adapted to soil moisture deficit. A set of 35 sesame genotypes with checks was used to quantify the variation in morpho-physiological, yield, and quality traits under irrigated (WW) and deficit soil moisture stress (WS) conditions in the summer seasons of 2021 and 2022. The analysis of variance revealed the presence of high variability among the genotypes for various measured traits. The mean performance indicated that WS negatively affects the growth, development, yield and quality traits. Moreover, the correlation, path analysis and D 2 analysis studies suggested that the traits, viz. leaf area (LA), total dry matter (TDM), canopy temperature (CT), number of branches per plant (NBP) and number of seeds per capsule (NSC) were significantly associated with seed yield under both the conditions. Quality traits like palmitic acid and oleic acid correlated positively with seed yield, particularly under WS. Furthermore, the genotypes with lower canopy temperatures were found to be better seed yielders under WS. In addition, mean performance and cluster analysis suggested that the genotypes: IC- 205776, JSCDT-112, JCSDT-26, IC-205610, and IC-204300, secured higher seed yield along with superior agronomical traits and net photosynthetic rate. These selected genotypes were most promising and could be used in future sesame crop improvement programmes.
