Assessment of organic and inorganic source of nutrients on yield and yield traits of black gram (Vigna mungo L.)

The present study was undertaken to assessment of organic and inorganic source of nutrients on yield and yield traits of black gram(Vigna mungo L.) cultivar “I PU-42”. An investigation was taken up during kharif season of 2018 at Suresh GyanVihar University, school of Agriculture Research Farm, Department of Agronomy, Jaipur (Rajasthan). The experiment was laid down in randomized block design (RBD), consisting of eight treatments which were replicated thrice for comparing the performance of cultivar “I PU-2 43” treated with different levels of organic and inorganic source of nutrients that were applied individually as well as in combination. The results indicates that treatment T6 that consists of 50%recommended doses of fertilizers (RDF) in combination with 50% vermicompost (VC)were far better than rest of treatments under study. It recorded significantly highest number of pods plant-1 (49.60), numbers of grains pod-1(5.53), 1000 grain weight (36.76 gm), harvest index (45.39%), grain yield (7.53 q ha-1) and straw yield (13.97 q ha-1) over rest of the treatments.
