Abstract:
New irrigation methods under different nutritional element supplies for maize production was designed and tested for evaluate quantitative and qualitative parameters by split-plot arrangement according complete randomized block design with three replications. Different Irrigation regimes was belonged to main plots (Conventional furrow irrigation: CFI or A1, Alternate furrow irrigation: AFI or A2 and fixed furrow irrigation: FFI or A3). Sub plots consisted (B1): Nitrogen + Phosphorus + or N + P as Control (C), (B2): Nitrogen + Phosphorus + Potassium or N + P + K, (B3): Nitrogen + Phosphorus + Potassium + Zinc or N + P + K + Zn, (B4): Nitrogen + Phosphorus + Potassium + Zinc + Boron or N + P + K + Zn + B and (B5): Nitrogen + Phosphorus + Potassium + Zinc + Boron + Iron or N + P + K + Zn + B + Fe. Results of analysis of variance showed that the interaction effects of different irrigation regime and fertilizer combinations on the characteristics of N Concentration, P Concentration, K Concentration, N Uptake, P Uptake, K Uptake, Number of seeds per row, 1000 seeds weight, leaf area index (LAI), Radiation use efficiency, seed yield, biological yield, number of seeds per row, was significant at 5% probability level. Interaction effects of treatments of irrigation regime and fertilization indicate that the Zn foliar increased concentrations of these elements in the seed. The highest and lowest of N, P and K uptake, seed yield and LAI were 117.56, 42.73, 55.7 kg.ha-1, 12950 kg.ha-1 3.86 and 113.42, 17.4, 16 kg.ha-1, 8894 kg.ha-1, 2.41 from Alternate furrow irrigation and (C+K, Zn, B, Fe) fertilizer treatment and fixed furrow irrigation and control respectively. The highest of light use efficiency were obtained from Alternate furrow irrigation and conventional furrow irrigation and (C+K, Zn, B, Fe) fertilizer treatment with 0.175 kg.kcal-1.m-2. In order to utilize the water sources efficiently and increase corn production under limited water supply, we propose the use of circular irrigation care along with instance, K, Zn, B and Fe fertilizer.
