Abstract
A field study was carried out during the two consecutive summer seasons of (2019 and 2020) at the Experimental Farm, Faculty of Agriculture, Al-Azhar University, Assiut governorate, located 375 km south of Cairo, Egypt. Aims study evaluation of some fast and slow-release nitrogen fertilizers in terms of speed nutrients loss and get maximum benefits from crop productivity. The experimental design was randomized complete block with three replicates. The experiment including five treatments; Control (Tc), 100% Ammonium Sulfate (AS) at the rate of 120 kg N feddan-1 (T1) (feddan = 4200 m² = 0.420 hectares = 1.037 acres), 100% Sulfur Coated Urea (SCU) at the rate of 120 kg N feddan-1 (T2), 100% Enciabean (EN) at the rate of 120 kg N feddan-1 (T3) and Poultry manure (PM) at the rate of 120 kg N feddan-1 respectively (Tp < /sub>). The obtained results in the highest N-uptake yield and yield component of maize as compared to the other treatments. Treatment T2 gave the highest biological yield was 12.44 and12.24 ton feddan-1 and grain yield was 2.34 and 2.68 ton feddan-1. Poultry manure treatments produced higher values for electrical conductivity (EC) was 1.06 and 1.12 dS m-1, Soil reaction pH was 7.89 and 7.76, organic matter (OM) was 39.53 and 40.77 g kg-1, available P was 16.32 and 17.64 ppm and available K was 345 and 451 ppm. The overall results suggest that slow-release N-fertilizers could be advised to grow maize plant under conditions of Egypt.
