| Abstract | ||
| Maximizing irrigation water productivity in irrigated crops, and expansion on organic agriculture are very important to overcome water shortage, and to improve environment preservation. Two field trails (summer seasons 2017 and 2018) were conducted at clay soil to examine the impact of, three amount of irrigation water (W); 100, 85, and 70% of ETC,, in conjunction with three fertilizer type; 100% of NPK (F1), 50% NPK + compost tea "CT" (F2), and 50% NPK + bio-fertilizer "BF" (F3), on ear parameters (length "CL", No. of row per ear "Cr", and grain mass per ear "Cm"), seed index "SI" (100 grain mass), harvest index "HI", grain yield "Gy", irrigation water productivity "IWP", and NPK uptake at shoots content. A split-plot design was used. Results illustrated that increasing water deficit (WD) percentage, resulted in progressively lower and significantly effect on all traits under study, and WD must not be less than 85%., of ETC. On the other hand, a combination of organic (CT and/or BF) with NPK fertilizer recorded over values at all traits compared of sole NPK. In addition, there were significant effects between F3 or F2 to F1, however, the increase between F3 and F2, was insignificant. | ||
