Abstract:
A field experiment was conducted at Crop Research Farm Suresh Gyan Vihar University, Mahal Jagatpura, Jaipur-Rajasthan during kharif season of 2018. The experiment was laid down in randomized block design (RBD) with three replications. A total of 8 treatments comprising of different organic and inorganic sources of nutrients including control were used in the present investigation to study their individual as well as interaction effect on growth, yield and economics of black gram cultivar “. It was revealed from the present investigation that all the parameters under study showed significant variation when subjected to different levels of organic and inorganic sources of nutrients including control (applied either individually or in combination). Appraisal of the data indicated that treatment-T₆ (50% recommended doses of fertilizers (RDF)+ 50% vermicompost) significantly improved the growth parameters viz., plant height (43.10 cm), dry weight (24.00 gm), number of root nodules (22.36), number of branches plant^-1 (4.86) and number of flowers plant^-1 (48.66), Same treatment also recorded significant enhancement in grain yield (7.32 q/ha) as well as in economics viz., net returns (₹ 28167) and B:C Ratio (2.09) of black gram over rest of the treatments under study.
