Abstract:
A field experiment was carried out at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during summer 2020 to study the effects of different organic sources on growth and yield of summer greengram. The results of investigation revealed that different sources of organic manures were found to be non-significant with respect to plant population and plant height while, significantly the highest branches per plant (3.76) was found with application of castor cake. In case of bioenhancers, seaweed extract resulted in the higher stature of plant height (36.52 cm) and number of branches per plant (3.73). Interaction effect was found not significant for all plant growth parameters. The yield attributes of greengram viz., number of pods per plant, pod length, number of seeds per pod, seed index, seed and stover yield were found to be non-significant due to different sources of organic manures. Seaweed extract spray has resulted highest value of yield attributes viz., number of pods per plant (13.23), pod length (9.18 cm), number of seeds per pod (8.61), seed yield (872 kg/ha) and stover yield (2046 kg/ha) of greengram. Interaction was found to be non-significant for yield attributes. The maximum net returns (₹26,213) was recorded with FYM incorporation and the maximum B:C ratio (1.75) was recorded with castor cake incorporation. As regards the bioenhancers tested, banana pseudostem sap spray resulted in maximum net returns (₹30,976) and B:C ratio (1.94).
