In the present investigation, 565 soybean MAGIC population lines along with 6 checks were evaluated in augmented design in 5 blocks at Agricultural Research Station, Adilabad during kharif, 2019-20 to study genetic parameters, character association and the direct and indirect effects of the traits on seed yield. Based on range, all the traits exhibited huge amount of variability. In the present study, the estimate of PCV was higher than GCV indicating the important role of environment in the expression of the characters under study. The highest genotypic and phenotypic coefficient of variation observed for the traits number of branches per plant (PCV- 33.53 %, GCV-20.15 %), number of pods per plant ( PCV- 32.35 %, GCV-21.11 %), net plot yield( PCV- 36.36 %, GCV-27.27 %) and seed yield per plant (PCV- 31.67 %, GCV-22.30 %) which indicates selection can be applied on these traits to isolate more promising line. The broad sense heritability was lower to higher for all the traits ranged from days to 50% flowering (20.02%) to days to maturity (75.87 %) while high genetic advance was recorded in all traits under study except, days to 50% flowering (2.99 %) and days to maturity (9.47 %).Among all the characters, high heritability along with high genetic advance as percent of mean was observed for plant height and net yield indicating predominance of additive gene action and a limited role of environment in the expression of these traits. Hence, these traits are fixable in nature and selection on the basis of these traits would be effective. Correlation studies indicated that number of branches/plot, number of pods/plant, net yield/plot, 100 seed weight and number of nodes/plant had significant and positive correlation with seed yield/plant.
The investigation was laid out on clay loam soil at Agricultural Research Station, Adilabad during rabi, 2020 with the aim to understand the chickpea crop performance with residue incorporation and use of biofertilizers along with varied NP recommended doses (0,50,75 and 100%). Results, revealed that, i.e., application of fertilizers i.e., 20:50:20 kg ha-1 N: P2O5:K2O recorded significantly higher grain yield (2558 kg ha-1) and stover yield (3255 kg ha-1) among all the treatments. Significantly superior nitrogen content (3.49 %), P content (0.53%), K content (1.62 %) and S content (0.34 %) by grain were observed with full dose of NPK application. Nutrient uptake of N (104.47 kg ha-1), P (15.29 kg ha-1), K (47.95 kg ha-1) and S (10.13 kg ha-1) by grain at harvest.
An investigation was carried out to “Study on seasonal incidence of Spodoptera litura (F.) on soybean” at Agriculture Research Station (ARS), Adilabad, Professor Jayashankar Telangana State Agricultural University during kharif, 2017 and 2018. The pooled results indicated that among different sowing dates viz., 15 th -18 th of June (sowing I), 25 th -28 th of June (sowing II), 5 th -7 th of July (sowing III), 15 th -17 th of July (sowing IV) and 25 th -27 th of July (sowing V) sowing I recorded minimum incidence (2.81 larvae/ meter row length) of S. litura population and maximum incidence in sowing II (4.34 larvae/ meter row length), similarly sowing I recorded minimum incidence (2.97 larvae/ meter row length) and maximum incidence in sowing II (4.34 larvae/ meter row length) during kharif, 2017 and 2018, respectively.
