EFFECT OF NANO-DAP ON QUALITY, CONTENT AND UPTAKE OF BLACK GRAM (VIGNA MUNGO L.) IN INCEPTISOL

The field experiment was carried out on "Effect of Nano-DAP on Quality, nutrient availability, uptake, and content in black Gram (Vigna mungo L.) grown in Inceptisol", during Kharif season of year, 2023-24 at research field, Department of Soil Science.College of Agriculture, Latur.The experiment was laid out in RBD with three replications and recommended variety of black gram TAU-1 as a test crop along with nine treatments.The results in nutshell indicated that the quality, content and nutrient uptake were significantly influenced by application of 100 per cent RDNP + S.T. of Nano-DAP+ F.A.@ 0.4 per cent of Nano-DAP at 20, 30 & 40 DAS.The growth parameters viz., plant height, number of branches, leaf area, no. of nodules plant -1 were significantly increased with application of 100 per cent RDNP + S.T. of Nano-DAP+ F.A @ 0.4 per cent of Nano-DAP at 20, 30 & 40 DAS (T 9 ) which was found at par with treatment T 8 (100 per cent RDNP + S.T. of Nano-DAP+ F.A.@ 0.4 per cent of Nano-DAP at 20 & 30 DAS), T 2 (100 per cent RDF + S.T. of Nano-DAP) and T 7 (75 per cent RDNP + S.T. of Nano-DAP+ F.A.@ 0.4 per cent of Nano-DAP at 20, 30 & 40 DAS).The improvement in quality parameters were recorded with application of (100 per cent RDNP + S.T. of Nano-DAP+ F.A @ 0.4 per cent of Nano-DAP at 20, 30 & 40 DAS) (T 9 ) i.e., Test weight, protein content, protein yield was increased significantly followed by treatments T 8 (100 per cent RDNP + S.T. of Nano-DAP+ F.A.@ 0.4 per cent of Nano-DAP at 20 & 30 DAS) and T 2 (100 % RDF + S.T. of Nano-DAP).Uptake of N, P, K in black gram was increased significantly with treatment T 9 (100 per cent RDNP + S.T. of Nano-DAP+ F.A@ 0.4 per cent of 30 & 40 DAS)
