Yield and Yield Components of Pumpkin (Cucurbita pepo L.) Influenced by Mycorrhiza, Vermicompost and Nanofertilizer

Abstract

The effect of mycorrhiza, vermicompost and nanofertilizer on yield and yield components of pumpkin (Cucurbita pepo L.), studied at research farm of Mianeh Branch, Islamic Azad University in 2014. A split-plot factorial experiment based on randomized complete block design with three replications was used. Three levels of vermicompost (0, 10 and 20 ton.ha-1) allocated in main plots and two levels of mycorrhiza (nonapplication and application) and foliar spray of three levels of nano micro-full chelate fertilizer (0 0/00, 2 0/00 and 4 0/00) allocated to subplots. The results indicated that vermicompost and interaction of vermicompost and nanofertilizer had significant effect on fruit weight, total dry weight, seed weight per fruit, number of seed per fruit, seed yield, fruit yield and fruit diameter. Also effects of nanofertilizer and interaction of vermicompost, mycorrhiza and nanofertilizer on fruit weight, fruit diameter and fruit yield was significant. The Maximum seed yield (418.84 kg.ha-1) and fruit yield (25552.30 kg.ha-1) were obtained from V2N2 and V2M0N1 treatments, respectively. The Minimum seed yield (145.17 kg.ha-1) andfruit yield (1870.17 kg.ha-1) were belonged to V0 and V0M0N0 treatments, respectively. Therefore, consumption of 20 t.ha-1 vermicompost with spraying nanofertilizer is suggested to obtain acceptable yield in pumpkin (Cucurbita pepo L.).
