Abstract
Two field experiments were conducted at Farm of Cairo University’s Faculty of Agriculture in Giza to evaluate a new glass fertilizer (GF) composition on pea plants. The compound is created by melting a variety of raw materials to acquire oxides (60% P2O5, 30% K2O, 3.5% ZnO, 3.5% MnO and 3% Fe2O3 wt %). Control treatment was a full dose of recommended chemical fertilizers (100% RDF), Whereas other treatments were GF at a rate of 60 kg fed−1, GF at rate of 30 kg fed−1, 50% RDF, 100% RDF ＋ biofertilizers, GF at rate of 60 kg fed−1 ＋ biofertilizers, GF at rate of 30 kg fed−1 ＋ biofertilizers, 50% RDF ＋ biofertilizers, and untreated treatment (without fertilizers). The results indicate that, the treatment 60 kg fed−1 GF plus biofertilizers induced increasing pea pod yield by 55.6% and 63.23% when compared with the control treatment in the first and second seasons respectively.
