Abstract

Aim: The objective of the present study was to assess the impact of conjunctive use of wool waste, farm yard manure and chemical fertilizer on soil properties of Aridisol of Bikaner, Rajasthan, India. ??

Methodology: After harvest of cabbage crop, soil samples were collected from the respective experimental plot of crop field by adopting the standard procedure. Bulk density, particle density, pH, electrical conductivity, organic carbon, available N, P, K, S, Zn, Cu, Mn, Fe, microbial count and dehydrogenase activity were estimated following the standard protocol.

Results: Application of wool waste @ 7.5 t ha^-1 along with FYM @ 7.5 t ha^-1 (W₁) significantly increased organic carbon and plant available nutrients (N, P, K, S, Zn, Cu, Mn, Fe) over control and rest of the treatment. but W₁ and W₂ (Wool waste @ 5 t ha^-1 along with FYM @ 10 t ha^-1) treatment was found at par with respect to nitrogen. Treatment W₁ also gave significant performance of microbial count and dehydrogenase activity during experimental season over rest of the treatment. Application of each increasing level of recommended dose of fertilizer significantly enhanced all chemical and biological properties of soil. Application of wool waste @7.5 t ha^-1 along with FYM @7.5 t ha^-1 increased available macronutrients and micronutrients over control.??     

Interpretation: It can be concluded that conjunctive use of wool waste, farm yard manure and inorganic fertilizer proved better nutrient management option for improving soil properties.

Key words: Aridisol, Enzyme activity, Farm yard manure, Macro & Micronutrients, Wool waste
