    EFFECT OF NUTRIENT MANAGEMENT PRACTICES ON YIELD AND QUALITY OF SPINACH (Beta vulgaris L.) GROWN ON ALFISOL
    (ACHARYA N. G. RANGA AGRICULTURAL UNIVERSITY RAJENDRANAGAR, HYDERABAD, 2005) RAMAKRISHNA, M; SITARAMAYYA, M
    A field experiment entitled “Effect of nutrient management practices on yield and quality of spinach (Beta vulgaris L.) grown on Alfisol” was conducted at Student’s Farm, College of Agriculture, Rajendranagar, Hyderabad during rabi 2004-05. Different nutrient combinations with N, P, K and FYM constituted the treatments. The effect of these treatments on yield, dry matter production, nutrient composition and quality parameters of the crop was studied. The experiment was laid out in a randomized block design (RBD) with twelve treatments, each replicated thrice. Spinach var. ‘All green’ was grown as test crop. The results indicated that the yield of spinach has significantly increased (16.16 t ha-1) with the application of recommended fertilizer dose @25 : 25 : 50 N, P2O5 and K2O kg ha-1. An yield advantage of 60 per cent over control was obtained with recommended dose of fertilizer application. Application of zinc or gypsum coupled with recommended fertilizer dose to the crop did not improve yields. All the four quality parameters viz., total carotene, vitamin C, protein and chlorophyll were the highest under recommended dose of fertilizers application. In general, nutrient concentrations of all nutrients were maximum with recommended dose of fertilizer application. Application of FYM was found to be beneficial in sustaining quality as well as nutrient composition of crop rather than yield. The role of nitrogen and potassium in maintaining quality of spinach was conspicuous. These observations clearly indicated the need for balanced fertilization for higher productivity and quality of spinach grown in Alfisols.
