The assessment of rice husk biochar, carpet waste, FYM and PGPR on nutrient uptake of Mungbaean (Vigna radiata L.)

摘要

The present experiment was conducted for improving nutrient uptake capacity and yield of crop using waste products of different activities and also useful in ecological stability of soil environment. Although, this objective is either an economic option for poor farmer or an effective strategy for increasing yield. The investigation was conducted in the organic farming plot of the Institute of Agricultural Sciences, BHU, Varanasi during kharif season of mungbean crop in 2014. The field experiment waslaid out in Randomized Block Design with 10 treatments and three replications. Application of BC2+ CW, + FYM, t ha"1 + PGPR showed significantly higher nitrogen content in grain (3.56 %) over control (Tj) which concluded that N content in grain and straw were found to increase significantly with increasing levels of biochar. Phosphorus and potassium content in grain and straw were found to increase with increasing levels of biochar but statistically non significant.
