Water resources are limited. Thus, one of the ways to prevent the decline of maize yield under water shortage conditions is the use of growth regulators. In this study, the effects of proline (150 mg/L) and salicylic acid (0.5 mmol) on the  yield and water use efficiency of maize were investigated under three irrigation regimes, including complete irrigation (control), 75% of complete irrigatio...

This study aims to evaluate the present management of border irrigation systems applied to wheat, alfalfa and sugar-beet farms in Boyer-Ahmad and Gachsaran cities in Kohgiloyeh and Boyer-Ahmad Province. Experimental farms included 8 alfalfa farms, 5 wheat farms and 5 sugar-beet farms. The experiments were conducted at different growth stages of plants and customary borders with prevalent dimens...

Irrigation water Scarcity is the major limiting factor for crop production in irrigated farming. Therefore, optimal use of water is influenced by seasonal rainfall especially where the water price is high. Nitrogen also plays a key role in plant nutrition. In this study, wheat grain yield production as a function of applied water (irrigation plus seasonal rainfall) and nitrogen fertilizer (appl...

In order to study the effect of physiological and biochemical responses of tomato cv. Rio Grande to foliar spray of Megafol under water deficit stress, an experiment was carried out in a split plot based on randomized complete block design with three replicates in Research Filed of university of Zanjan as during 2015. Treatments consisted arrangement of three irrigation levels (starting irrigat...

In order to study the effects of cycocle and plant growth promoting rhizobacteria (PGPR) on yield, Chlorophyll fluorescence parameters and some physiological traits of wheat under water limitation condition, a factorial experiment based on randomized complete block design with three replications was conducted at the research farm of faculty of agricultural sciences, University of Mohaghegh Arda...

In order to assess the effect of drought stress and various levels of potassium on solutes accumulation and chlorophyll of canola and Indian mustard, a field experiment was conducted in a factorial design based on randomized complete block design with three replications including three irrigation regimes (I1=irrigation after 50% depletion of soil water(control),I2 =irrigation after 70% water de...
