Abstract
ABSTRACT: Plastic house experiment was conducted during 2013/2014 and 2014/2015 seasons, at the experimental site of Central Laboratory for Agricultural Climate (CLAC), Agriculture Research Center, Giza, Egypt. This work aims to investigate the effect of application of rock phosphate and phosphate solubilizing bacteria on growth and yield of sweet pepper (Slevit F1 Hybrid) grown on rice straw substrate. Phosphate solubilizing bacteria were applied as mixture of Bacillus polymyxa and Bacillus megaterium (1:1) for once, twice or thrice times (after 1; 1 and 3 or 1, 3 and 5 weeks from transplanting respectively). The control treatment received mineral phosphate fertilizer (calcium super phosphate) without phosphate solubilizing bacteria. The results clearly showed that the highest values of all vegetative characteristics, mineral percent (NPK) and yield of pepper were recorded with rock phosphate + inoculation of phosphate solubilizing bacteria for twice or thrice times treatments. The lowest values of all parameter were resulted by using rock phosphate without phosphate solubilizing bacteria. There were not significant differences between rock phosphate with inoculation of phosphate solubilizing bacteria for once and control treatment. This work showed that applying rock phosphate with phosphate solubilizing bacteria produced sweet pepper plants superior in growth and yield comparing with those fertilized by calcium super phosphate fertilizer, as well as provides an environmentally friendly method to manage rice straw as agriculture substrate instead of burning.
