Effect of different organic sources on yield and yield attributing character of watermelon (Citrullus lanatus Thunb.)

Abstract

The experiment on effect of different organic sources on yield and yield attributing character of watermelon (Citrullus lanatus Thunb.) was carried out at Organic Research and Training Centre, Vasantarao Naik Marathwada Krishi Vidyapeeth, Parbhani. during summer season in year 2018-19. The experiment was laid out in Randomized Block Design in nine treatments with three replications. The treatments were T1 [RDF 100% through FYM], T2 [RDF 100% through vermicompost], T3 [RDF 50% through FYM + RDF 50% through Vermicompost], T4 [RDF 100% through FYM + Jeevamrut 3 Application], T5 [RDF 100% through vermicompost + Jeevamrut 3 Application], T6 [RDF 100% through FYM + Biofertilizer (Azotobacter)], T7 [RDF 100% through Vermicompost + Biofertilizer (Azotobacter)], T8 [RDF 100% through FYM + Panchagavya 3 Application] and T9 [RDF 100:50:50 N:P:K (Control) Kg/ha]. In respect of yield attributing character it was also observed that in treatment T6 [RDF 100% through FYM + biofertilizer (Azotobacter)] was found with high fruit weight of watermelon (1.81 kg), maximum weight of pulp per fruit (1.47 kg), maximum length of fruit (25.67 cm) of watermelon, maximum diameter of fruit (15.27 cm), minimum days required for first harvest of fruit of watermelon (78.00 days) and minimum days for total harvest of fruit of watermelon (97.93 days) as compared with other treatment and also in case of yield the treatment T6 [RDF 100% through FYM + biofertilizer (Azotobacter)] was found with high number of fruits per vine (1.80), high yield and of fruits per vine (3.258 kg) and high yield of fruits per hectare (57.9175 t/ha) as compared to other organic sources and control.
