Abstract:
An experiment was carried out during 2017-18 with the objectives to study the effect of different fertigation levels of nitrogen, phosphorus and potassium through fertigation on growth, yield and quality of pumpkin and to find out the suitable combination of nitrogen phosphorus and potassium fertigation levels for better growth, yield and quality of pumpkin. The experiment was laid out in Randomized Block design (RBD) with six treatments viz., T1 50:25:00 NPK Kg ha^-1, T2 75:25:25 NPK Kg ha^-1, T3 100:50:25 NPK Kg ha^-1, T4 100:50:50 NPK Kg ha^-1, T5 125:50:50 NPK Kg ha^-1 and T6 150:50:50 NPK Kg ha^-1 replicated four times. The various growth parameters in respect to vine length (455.50 cm), number of branches (14.49), internodal length (16.53 cm), days required to bear 1^st female flower (58.00 DAS) and female flowers per vine were significantly maximum in T4. As regard the yield and yield contributing parameters, number of fruits per vine (2.40), diameter of fruit (15.75 cm), thickness of flesh (2.78 cm), diameter of fruit cavity (11.62 cm), volume of fruit (789.73 cm3), yield per vine (10.68 kg), yield per plot (320.52 kg) and yield per hectare (203.50 q) were found significantly maximum in the T4.
