Abstract

The field experiment consisted of twelve treatment combinations involving three inorganic fertilizers viz. F1:100:40:40, F2:125:50:50 and F3:150:60:60 kg NPK/ha and three growth regulator sprays viz. G1: Ethrel 200 ppm, G2: GA3 25 ppm G3: NAA 100ppm and control (water spray). Results revealed that higher seed yield per ha (541.0 kg) was recorded at the fertilizer level of 150:60:60 kg NPK/ha followed by F2 (125:50:50 kg NPK/ha) and F3 (100:40:40 kg NPK/ha) which recorded 379.0 kg/ha and 284.0 kg/ha, respectively. Similarly foliar spray of Ethrel at 200 ppm registered significantly higher seed yield of 524.0 kg/ha followed by NAA at 100 ppm (471.0 kg/ha) and lowest yield at control (265.0 kg/ha). The combined effect of NAA 100 ppm and 150:60:60 kg NPK per ha application resulted maximum seed yield with better quality in pumpkin cv. Arka Chandan.
