Abstract:

This study investigates the effect of integrated nitrogen management (INM) on yield and soil properties under cauliflower (Brassica oleracea var. botrytis L.) cv. Nuzi Snow White at Students’ Research Farm, P.G. Department of Agriculture, Khalsa College, Amritsar during Rabi season of 2017-18. For INM studies, organic manures viz., vermicompost (VC), farmyard manure (FYM) and recommended dose of nitrogenous fertilizers (RDNF) was employed. The experiment was laid out in Randomized Block Design (RBD) with eight treatments comprised of T1: Control, T2: 100 % RDF, T3: 75% RDNF + 25% N (VC), T4: 50% RDNF + 50% N (VC), T5: 75% RDNF + 25% N (FYM), T6: 50% RDNF + 50% N (FYM), T7: 50% RDNF + 25% N (VC) + 25% N (FYM), T8: 75% RDNF + 12.5% N (VC) + 12.5% N (FYM). The availability of macro and micronutrients were significantly improved by integrated use of nutrient sources. Maximum values of available N, P, K and S were observed to be 255.90 kg ha-1, 25.18 kg ha-1, 308.65 kg ha-1 and 11.97 kg ha-1, respectively in a treatment where 50% recommended nitrogen was supplied through VC (T4). Similarly, available micronutrients (Zn, Fe, Cu and Mn) were also found highest in treatment T4. Exchangeable Ca and Mg in soil varied from 58.47 to 33.47 mg kg-1 and 6.73 to 11.87 mg kg-1, respectively. Values regarding plant growth parameters, yield as well as nutrient uptake were noticed highest in T2 (100% NPK through inorganic fertilizers) which was at par with T3 in which 25% N was substituted through VC. Integrated application of organic inputs along with 25% reduced chemical fertilizers proved to enhance the soil health while sustaining crop productivity.
