Abstract:
The investigation was carried out on impact of major nutrient and gypsum on soil physico-chemical properties, and results revealed that combined application of NPK @ 25:50:20 kg ha^–1and T₄G₄₀₀ kg ha^-1 of gypsum in the soils significantly reduced the various attributes of soil nutrients, and results revealed that gypsum application methods in surface layer observed that NPK content in soils were significantly lower in control plot due to no NPK was applied in these treatments. The oil content in groundnut was found to be significantly lower in control in comparison to other gypsum application methods. Oil content in T₁G_100, T₂G₂₀₀ and T₃G₃₀₀were at par with each other. However, oil content in T₄G₄₀₀was found to be significantly superior with each other. Gypsum application methods, NP and K uptake in groundnut was found to be significantly lower in control in comparison to other gypsum application methods. Groundnut nitrogen uptake inT₂G₂₀₀, T₃G₃₀₀ and T₄G₄₀₀ were statistically at par with each other. However, groundnut nitrogen uptake in T₁G₁₀₀ was significantly lower than inT₂G₂₀₀, T₃G₃₀₀ and T₄G₄₀₀. But P and K uptake in groundnut was statistically similar to each other treatments. Overall, we can conclude that gypsum application under Sodic environment create feasible environments for better nutrient uptake, proper infiltration and aeration, increased N, P and K availability and optimum pH for proper growth and quality of groundnut.
