Effect of NPK levels and spacing on growth & yield of pointed gourd

Among the various N,P,K level studied, the highest value for main vine length and internodal length was recorded with 175:70:70 NPK Kg ha-1 (F3), consequently the lowest values were recorded for floral parameters viz., days taken for opening of first male flower and days taken for opening of first female flower with 125:50:50NPK Kg ha-1 (F1). The application of 150:60:60 NPK Kg ha-1 (F2) recorded the highest values for the parameters number of nodes per vine, number of primary branches per vine, number of fruits per vine, fruit length, fruit diameter, yield per vine, yield per plot, total yield, number of seeds per fruit, fruit retention percentage, 100 seed weight, ascorbic acid content, protein content, reducing sugars, total sugars and total soluble solids and recorded lowest values for node at which first male flower appeared, node at which first female flower appeared , days taken to first harvest and days taken from fruit set to marketable maturity.
