The objective of this study was to evaluate the effect of soil moisture condition and irrigation regime on the bioelectric potential of crops with different growth stages. The bioelectric potential of broccoli (Brassica oleracea var. italica) plants at the initial and mid-growth stages was measured under different soil moisture conditions and irrigation regimes using pot experiments. The result...
Limitation of suitable water resources is the most important problem of agriculture in Iran. Considering the condition of shallow and saline groundwater in many parts of Iran, and relative resistance of safflower to salinity, it is necessary to study the contribution of groundwater to water consumption of safflower. In this research, the effects of different water table depths and salinity of g...

To investigate the effect of deficit irrigation on yield of mung bean genotypes, an experiment was conducted as a split plot in randomized complete block design (RCB) with three replications. The main plot was irrigation regime in three levels (supply of 100, 80 and 60% of crop water requirement) and subplot was genotype in five levels (VC 11-18b, VC 63-72, CN-9-5, NM 54 and 1-61-145). The resu...
this study was carried out to evaluate the association between laboratory seed characteristics and seedling emergence of canola cultivars that it's were produced under different irrigation regime and planting date. the treatments were included two planting date and two levels of irrigation (main factors) and seeds of five canola cultivars (sub factor) which in first year (2006-2007) had be...
The success of seedling establishment of desert plants is determined by seedling emergence response to an unpredictable precipitation regime. Sand burial is a crucial and frequent environmental stress that impacts seedling establishment on sand dunes. However, little is known about the ecological role of seed mucilage in seedling emergence in arid sandy environments. We hypothesized that seed m...
The impact of water deficit on berry quality has been extensively investigated during the last decades. Nonetheless, there is a scarcity of knowledge on the performance of varieties exposed to a combination of high temperatures/water stress during the growing season and under vineyard conditions. The objective of this research was to investigate the effects of two irrigation regimes, sustained ...
in order to study the effect of fertilizing treatments and limited irrigation regimes on yield and yield components of isabgol, a field experiment was conducted at experimental farm of college of agronomy and animal sciences, university of tehran. the experimental design was a split plot based on a randomized complete block design with three replications. in this research four irrigation regime...
BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Improve saving water in irrigated agriculture and thereby improving water use efficiency is of paramount importance in water-scarce regions. OBJECTIVES: This study was conducted to assessment effect of different levels of irrigation re...
To study the effects of delayed irrigation on growth and ratoon of millet (Pennisetum americanum cv. Nutrifeed) in the first harvest and sorghum (Sorghum bicolor cv. Speedfeed), a field experiment was conducted as split plot based on a randomized complete blocks design with three replications in Faculty of Agriculture, Vali-e-Asr University of Rafsanjan, Iran, at summer 2014. Factors consisted...
