Assessment Effect of Different Irrigation Regime and Fertilizer Combinations on Seed Yield, Radiation Use Efficiency and Biochemical Parameters of Corn
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.

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Effect of Different N Fertilizer Combinations and Irrigation Regimes on Concentration, Uptake and Efficiency of Major Nutrients in Plantago ovata
In order to evaluate the response of major nutrients concentration, uptake and their efficiencies of isabgol (Plantago ovata) to N fertilizer combinations and irrigation regimes, a field experiment was conducted at the agricultural research farm of Shahrekord University, 2009. The experiment was arranged as split-plot, in randomized complete block design with three replications. The irrigation ...متن کامل

Effects of different irrigation methods and hormone application on water use efficiency, yield, and leaf biochemical traits in potato
Investigation of different irrigation methods on plants is necessary due to limited water resources and the increasing need for food products. The purpose of this study was to evaluate the effect of sprinkler and drip irrigation systems and hormones on morphological and physiological characteristics of potato. Treatments included sprinkler and drip irrigation systems and hormones (gibbere...متن کامل

The Effect of Different Amounts of Irrigation and Planting Methods on Water Use Efficiency, Grain Yield and Some Physiological and Biochemical Traits of Wheat (Triticum aestivum L.)
This research was conducted at the research field of West-Azerbaijan (Saatloo station, 45° 10′ 53˝ E/ 37° 44′ 18˝ N and 1338 m above sea level), located 25 km from Urmia city (Iran) during 2019-2020 cropping seasons, as a factorial layout based on randomized complete block design with three replications. The first factor was irrigation regime at three levels (supplying 100, 75 and 50% of net ir...متن کامل
