Abstract:
The field experiment was conducted at the experimental farm of Udai Pratap Autonomous College, Varanasi (U.P.) to evaluate the response of applied major nutrient with gypsum on physical properties in test crop field. The study was carried out with five treatments and four replications in randomized design. The results revealed that combined application of NPK @ 25:50:20 kg ha^–1and T₄G₄₀₀ kg ha^-1 of gypsum in the soils significantly reduced soil dry bulk density by about 6.93% when compared to the control. The significantly highest soil particle density in 4.57 g cc^-1, pore space 11.47%, hydraulic conductivity 8.46, infiltration rate 17.37 and water stable aggregates were found in plots with a combination of NPK and gypsum at @ 25:50:20 kg ha^–1 and T₄G₄₀₀ kg ha^-1 respectively. The significant treatment differences on soil mechanical and physical properties of the study soil due to effect of the treatments could be attributed to the ability of Ca and S applied via gypsum to flocculate soil particles. Thereby, creating an enabling to better soil physical properties, infiltration and aeration for proper growth and quality of groundnut.
