The present study pertains to the effect of N,P,K levels, plant densities and its interaction on growth, yield and quality of pointed gourd (Trichosanthes Dioica Roxb.) was undertaken at College of Horticulture, Dr. Y.S.R Horticultural University, Venkataramannagudem, West Godavari District of Andhra Pradesh during kharif 2015-2016. An experiment was carried out with 12 different treatment combinations in factorial randomized block design (FRBD) replicated thrice which are (T1)- F1 S1: 125:50:50 NPK kg ha-1+1mx1m; (T2)-F1 S2: 125:50:50 NPK kg ha-1+1.5mx1.5m; (T3)- F1 S3: 125:50:50 NPK kg ha-1+1.5mx1m; (T4)- F2 S1: 150:60:60NPK kg ha-1+1mx1m; (T5)- F2 S2: 150:60:60NPK kg ha-1+1.5mx1.5m; (T6) F2 S3: 150:60:60NPK kg ha-1+1.5mx1m; (T7)- F3 S1: 175:70:70 NPK kg ha-1+1mx1m; (T8)-F3 S2: 175:70:70 NPK kg ha-1+1.5mx1.5m; (T9)- F3 S3: 175:70:70 NPK kg ha-1+1.5mx1m; (T10)-F4 S1: Control+1mx1m; (T11)-F4 S2: Control+1.5mx1.5m; (T12)- F4 S3: Control+1.5mx1m. Among the treatment combinations of N,P,K levels and plant densities, the treatment combination (T6) F2 S3:150:60:60 NPK kg/ha + 1.5m x 1m recorded maximum values for growth, yield and quality parameters viz., 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, ascorbic acid content, protein content and total soluble solids and the minimum values were recorded for the parameters 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. However, the application of (T8)-S2F3:175:70:70 NPK Kg ha-1 + 1.5m x 1.5m recorded maximum main vine length and internodal length whereas (T3)- F1 S3: 125:50:50 NPK Kg ha-1 + 1.5m x 1m recorded minimum days taken for opening of first male flower and days taken for opening of first female flower. The application of (T5)- F2 S2: 150:60:60 NPK kg/ha + 1.5m x 1.5m recorded maximum weight of edible fruit, 100 seed weight, reducing sugars and total sugars.
