Two field experiments were carried out on sweet pepper Capsicum annuum L. cv. California Wonder at the Experimental Farm of the Faculty of Agriculture, Moshtohor, during the summer seasons of 2000 and 2001. The first experiment dealt with the effect of inoculating sweet pepper seeds and transplant roots with a single or mixed biofertilizer; Nitrobin and/or Phosphorin in addition to the 0, 25, 50, 75% of the required N and/or P fertilizer level. Results showed that the most favorable treatment was that inoculated with Nitrobin + Phosphorin and fertilized with 75% of the required N and P level; 60 kg N + 48 kg P2O5 + 96 kg K2O, which gave the highest growth, yield and fruit quality of sweet pepper in both seasons.
The second experiment studied the response of sweet pepper plants to 4-organic fertilizer sources (Biogas, FYM, Agrolig and Chicken manure) within 4-methods of N-application. Results showed that plants which received 30 kg N as Biogas + 30 kg N in its mineral form + 64 kg P2O5 + 96 kg K2O, gave the best growth, yield and fruit quality as a general trend in both seasons.
