Damage caused by water shortages leads to physiological and biochemical changes in metabolism of plants and make them predispose to attack by pests and diseases and reduce the quality of the crops. In order to evaluate the effect of supplemental irrigation on safflower fly (A. helianthi) population of safflower cultivars, an experiment conducted as a split plot based on randomized complete bloc...

In the present study, some nutritional imbalances, specific ion toxicity and yield-ion concentration relationships in maize under water, nitrogen (N) and salinity stresses were assessed. Effect of different levels of irrigation water (I1=1.0ETc+0.25ETc as leaching, I2 =0.75I1 and I3 =0.5I1) as main plot, salinity of irrigation water (S1=0.6, S2= 2.0 and S3=4.0 dS m-1) as sub-plot and N fertiliz...

in order to investigate the effect of nitrogen fertilizer on tea yield and yield components in supplemental irrigation and rain fed conditions an experiment was conducted at feshalam tea research station in fouman (guilan) during (2008-2010). in this study, line-source irrigation technique and the strip plot experiment on randomized complete block design was used. six levels of nitrogen, zero, ...

The current study was carried out at the experimental farm of Rana Sugars Ltd., Buttar Seviyan, Amritsar, Punjab, India, to identify methods improve yield and quality ratoon sugarcane in potassium-deficient soils. treatments comprised two levels irrigation, resulting plants which either received sufficient water (I1) or were water-stressed (I2), four rates potassium (K) application: 0 (K1), 40 ...

A field experiment was performed in order to evaluate the effects of irrigation and application of K fertilizer on seed storage proteins  in chickpea, ILC-482 cultivar. Experiment was performed in factorial using randomized complete block design with three replications. In this experiment, two factor consist of irrigation in three levels (I1= non irrigation and I2= irrigation in flowering stage...

Salinity and drought are some of the main problems affecting global crop yields. In this study, interaction effects irrigation interval salinity on yield, soil salinity, other parameters black carrot were evaluated in a covered rain shelter. The treatments consist three different intervals (4 days (I1), 6 (I2), 8 (I3) with water levels (0.38 (S1), 1.5 (S2), 3.0 (S3), 5.0 (S4) 7.0 (S5) 10.0 (S6)...
