The study was conducted at Agricultural Research Centre with the objective of identifying best-performing perennial grass species under supplemental irrigation and advising promising cultivated fodder for smallholder livestock producers. Randomized Complete Block Design six three replications employed. used were T1 (Brachiaria mutica_18659), T2 (Cynodon aethiopicus), T3 (Pennisetum sphacelatum)...

Sprinkler irrigation is a common farming practice in those states where the semi-arid climate and lack of sufficient rainfall during critical growing periods necessitate the use of supplemental water. The source of most irrigation water is groundwater which can be contaminated with volatile organic compounds (VOCs). Since the groundwater may be the primary or only source of drinking water for a...

A methodology has been developed for predicting the future growth in demand for irrigation in countries with supplemental irrigation such as England and Wales. This takes into account expected changes in agricultural policy, technical, market and other factors. The methodology has also been applied within a geographical information system (GIS) to map the growth. The GIS approach represents an ...

Poor irrigation water management is one of the major factors limiting crop production inEthiopia. This study was, therefore, conducted at three different locations in the southeasternEthiopia for 2 consecutive years to investigate the effects of different irrigation depths andintervals with furrow irrigation system on tuber yield, biomass yield and water use efficiency ofpotato. The treatments ...

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, ...

Insufficient water is the greatest limitation to crop production and choice of crops grown in the Northern Great Plains. Supplemental irrigation can overcome this limitation. Uncertainties about the drainage capacity of flne-textured subsoils and the effect of irrigation on soil properties has impeded irrigation development. In this study we quantified salinity changes in soils with fine-textur...
