Abstract:
A field experiment was carried out at Agronomy Instructional Farm, C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, during summer season of 2020 to study the influences of different organic sources and seaweed extract on quality, nutrient content, uptake, soil fertility status and soil microbial population after harvest of summer greengram (Vigna radiata L.). Significantly highest protein yield (208.31 kg/ha) was found with seaweed extract @ 10%. Significantly the highest uptake of N (71.69 kg/ha), P (4.97 kg/ha) and K (31.46 kg/ha) by the greengram were obtained with seaweed extract @ 10%. Significantly higher K uptake (32.61 kg/ha) was recorded with combined application of FYM and seaweed extract (O₁B₂). Significantly the highest available P₂O₅ content (43.56 kg/ha) in soil was recorded with the application of vermicompost @ 2 t/ha; while, different sources of organic manures were found to be non-significant with respect to the available N and K₂O. Significantly highest post-harvest microbial status of Rhizobium and PSB (102.56 and 134.50 CFU × 10⁵/g soil) were recorded with the application of vermicompost @ 2 t/ha. From the bioenhancers, significantly the highest post-harvest status of, PSB (172.25 CFU × 10⁵/g soil) with panchagavya @ 3% and Rhizobium (127.25 CFU × 10⁵/g soil) was found with seaweed extract @ 10%.
