Effect of STCR-IPNS Based Nutrient Application on Soil Health, Yield, Nutrient Content and Uptake of Mustard (Brassica juncea L.) in Eastern Plain Zone of Uttar Pradesh, India

Le résumé fourni par la source

The improvement in grain yield characters was the manifestation of improved growth characters as a result of higher uptake of nutrients caused by balanced supply of nutrients in this regard soil test based nutrient management approaches aims provide a scientific basis for balanced fertilization to obtain more yield per unit of fertilizer investment. An experiment was conducted during kharif season 2017-18 in the Soil Science and Agricultural Chemistry Research Farm, SHUATS, Prayagraj. The cursory glance of data revealed that the bulk density and particle density of soil was found to be non-significant in different levels of fertilizer recommendation based on soil test values. The maximum soil pore space (60.37%) and water retaining capacity (81.25 %) was recorded in treatment T4 [STCR + 5 t FYM]. The maximum available Nitrogen (305.82 kg ha-1), available Phosphorus (26.90 kg ha-1), available Potassium (205.07 kg ha-1) and available Sulphur (14.23 ppm ha-1) in soil was recorded in treatment T8 [STCR + @ 50 % FYM + @ 50 % S]. The maximum seed yield of mustard (11.53 q ha-1) and stover yield (16.03 q ha-1) was associated with the treatment T8 [STCR + @ 50 % FYM + @ 50 % S]. Result showed that that application of T8 [STCR + @ 50 % FYM + @ 50 % S] significantly recorded maximum nutrient content viz. N (2.19%), P (0.23%), K (1.68%) and S (4.8%) content in grain N (1.73%), P (0.21%), K (1.47%) and S (3.9%) content in stover and maximum nutrient uptake viz. N (25.25 kg ha-1), P (2.65 kg ha-1), K (19.37 kg ha-1) and S (55.34 kg ha-1) uptake in grain is and N (27.73 kg ha-1), P (3.36 kg ha-1), K (23.56 kg ha-1) and S (62.51 kg ha-1) uptake in stover.
