the rectangular broad crested weirs are widely used to measure the water dischargewhich is one of the most popular tools in the irrigation canals particularly, in developingcountries.the present article is trying to demonstrate the results of an experimental work carriedout on rectangular broad crested weir with sloped upstream face to investigate the effect ofupstream slope on discharge effici...

in order to find the most appropriate planting patter and cultivar of grain corn, an experiment was conducted in agriculture research station of jiroft and kahnooj, iran for two years in 2007 and 2008 as a split-plot experiment based on a randomized complete blocks design with three replications. the main plot was planting patter at four levels of normal planting (single-row on one furrow), dou...

soil infiltration characteristics affect the design, evaluation and management of furrow irrigation over afield. on the other hand, different variables influence furrow infiltration, making infiltration modeling for afield a complex process. this study was conducted to investigate the direct and indirect effects of allvariables affecting furrow infiltration. the blocked furrow method was used t...

Background: Land configuration decides the effectiveness of crop management practices and major land practice includes raised bed preparation, ridges furrows, broad furrows etc. The farmers’ sowing in flatbed without proper configuration, leads to poor growth development crops. A large portion residues is burnt by farmers fields clear left-over straw stubbles. Conservation agriculture involving...

in order to improve the efficiency of irrigation systems and investigate their impact on the pest population levels, furrow and sprinkler irrigation systems were compared in sugar beet fields. in this study, three different fields were chosen and irrigated by one of the furrow, classic and center pivot irrigation systems.  in each field, 20 plots were randomly selected of which 10 plots were ma...

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 A...
