Abstract |
Two field experiments were conducted on sandy soils at Ismailia Agric. Res. Station during winter seasons of 2002/2003 and 2003/2004 to study the response of wheat plants to different rates and sources of N-fertilizers. Five rates of mineral fertilizer (0. 30. 60. 90 and 120 kg N/fed),as individual treatments or in combination with two sources of N-fertilizers (Organic, Bio-fertilize4s) were used. The results showed that grain and straw yields as well as their NPK contents increased significantly with increasing N-mineral rates up to 90 kg/fed. Also, the addition of N-organic (compost) and/or biofertilizer affected significantly wheat grain, straw yields and their NPK contents, but the increases were less than obtained by applying N-mineral. Also, it was noticed that each of nitrogen use efficiency and agronomic efficiency tended to decrease with increasing N-mineral fertilizer, while their values increased with increasing the ratio of N-organic: N-organic in their mixtures
