Effect of different organic manures and bio-enhancers on growth and yield of greengram (Vigna radiata L.) under organic farming

An experiment entitled “Effect of organic manures and bio-enhancers on growth and yield of greengram (Vigna radiata L.) under organic farming” was carried out at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during the year 2023. The experiment was laid out in randomized block design with having twelve treatments and three replications. The results of present investigation revealed that different sources of organic manures and bio-enhancers were found non-significant with respect to plant population, plant height, number of branches per plant and fresh weight of root nodules per plant while, significantly highest number of root nodules per plant (24.56) was found with application of FYM @ 5t/ha + Jivamrut @ 500 l/ha. While the application of FYM @ 5t/ha + Panchgavya @ 4% spray, recorded significantly higher number of pods per plant (28.91), seed yield (961 kg/ha), stover yield (1601 kg/ha), protein content (23.82%) and protein yield (229 kg/ha). The study revealed that higher yield, net return and maintaining soil fertility under organic farming, kharif greengram should be fertilized with farm yard manure @ 5 t/ha, along with either foliar spray of panchgavya @ 4% spray, at the time of branching and flowering stage, or soil application of jivamrut @ 500 l/ha or amritpani @ 500 l/ha at the time of sowing and 30 DAS.
