A field experiment was conducted to study the effect of deficit irrigation and mulch levels on soil physical properties and growth and yield of maize crop. The experiment comprised of two irrigation levels, i.e. I1: 558.8 mm and I2: 711.2 mm while two mulch levels, i.e. M0: no mulch and M15: 15 Mg ha. Soil samples were collected from 0-10, 10-20, and 20-30 cm depths before sowing and at crop ha...

background & aim: drought stress, as a main abiotic stress, has a significant influence on growth and metabolic activities of plant species. in this study, the influence of reduced irrigation on dry herbage, essential oil yield, and chemical components of two thyme species were investigated. experimental: this study was done in an experimental greenhouse, i.a.u., shahrekord branch, iran at...

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...

introduction: fao aquacrop model (raes et al., 2009a; steduto et al., 2009) is a user-friendly and practitioner oriented type of model, because it maintains an optimal balance between accuracy, robustness, and simplicity; and it requires a relatively small number of model input parameters. the fao aquacrop model predicts crop productivity, water requirement, and water use efficiency under water...

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...

to study the effect of planting pattern and water quantity on potato yields under drip irrigation, this research was conducted using a split plot based on a randomized complete block design with four replications in three regions (mashhad, ardebil and damavand, iran) during 2003-2004. nine treatments were used. the main-plots were three levels of irrigation: 100%(i1), 80%(i2), and 60%(i3) of cr...

A field experiment was conducted in sandy loam soils to study the Growth and Yield parameters of six different crops with limited number irrigations under a zero-till system rice fallows during rabi, 2021-22 at Agricultural College Farm, Naira. The laid out split-plot design, replicated thrice three irrigation levels viz., two (I1), (I2) four (I3) assigned main plots fallow Maize (C1), Sorghum ...
