Abstract

In Egypt, we have a big gap between our production and consumption of edible oil accounted by more than 95%. In recent few years many attempts and efforts were pushed to increase our production, one of these attempts is intercropping of oil summer crops with maize to increase the production in addition to provide the soil with natural nitrogen. Therefore, two field experiments were carried out at Mallawi Agricultural Research Station, Minia, ARC, during 2018 and 2019 seasons, to study the effect of intercropping three oil crops on productivity, quality and profitability of maize and using different rates of N nano + mineral fertilizer .A complete Randomized Block Design in a split plot arrangement. Main plots were devoted for the following soybean, groundnut and sesame 50% of the recommended. The following rates of fertilizer , 100 % N mineral fertilizer, 100% N nano fertilizer,75% nano+25% mineral fertilizer, 50% nano + 50% mineral fertilizer and 25 % nano+ 75% mineral fertilizer added for maize and three oil crops from recommended does were allocated in the sub- plots. The intercropping groundnut with maize gave the highest values of grain yield (23.25 & 21.61) ardab/fad in the both seasons respectively. The intercropping groundnut with maize and using 75% N nano fertilizer +25% N mineral fertilizers recorded the highest values for land Equivalent Ratio (LER). The pattern of maize- 50% groundnut intercrop fertilized with 75% nano fertilizer N +25% mineral fertilizer N of the recommended for maize were more profitable for farmer.
