Abstract:
Production of the pulses is not adequate to meet the national demand in India. Along with extremely limited use of biofertilizers farmers are still facing a diverse technological gap in the cultivation of black gram. The present investigation is carried to study the effect of different treatments for summer black gram on the quality of grain and post-harvest soil fertility status of the soil. Field experiment is conducted during the summer season of the years 2020 and 2021 on Black gram variety Gujarat 1 in fruit zone area of Marwadi University, Gauridad, Rajkot (Gujarat). Six treatments comprised of alone and combined application of chemical fertilizers (50% and 100% RDF) and biofertilizers (Seed treatment with Rhizobium and application PSM on the soil) following randomized block design (RBD) with four replications. The results of the experiment revealed that treatment T6 (Rhizobium inoculation + PSM +100% RDF) produced significantly the maximum protein content 25.18% which was superior over of other treatments in the pooled results. Treatment T6 (Rhizobium inoculation + PSM +100% RDF) increased significantly the available nutrients such N and P in the soil after harvest of the crop. However, available nitrogen in the soil after harvest remained statistically on par with treatments T2, T5 and T3 in the pooled results. The data indicated that treatment effect was found non-significant in both the years as well as in pooled results, which reveals that the treatments did not exert any adverse effect on available potassium in the soil after harvest of summer black gram.
