the main objective of this research is to determine water use efficiency (wue) of some major crops under farmer's management in the different region of iran including kerman, hamedan, moghan, golestan and khuzestan provinces. the research also attempted to assess and identify the sources of inefficiencies in improving wue. based on methodology, wue was determined by measuring crop yield (k...

A trickle irrigation experiment on sugarcane was established in October 1985 on the SASA Experiment Station farm at Shakaskraal. The objectives were to establish suitable operating procedures, to measure cane yield potential, and to study the effects of factors such as fertigation and crop row spacingon yieldsoftrickle irrigated sugarcane. The results ofthe plant and first ratoon crops of this ...

A layer of harvest residues from the previous crop can reduce wasteful evaporation from the soil surface and thereby increase the efficiency of use of limited water resources for agricultural production. The practice of harvesting sugarcane green and leaving crop residues in the field, as opposed to burning the residue, has been re-adopted in many sugarcane industries worldwide. However, a bett...

The Ord River Irrigation Area is 3200 km NE of Perth on latitude 15 30’ S, at an altitude of less than 100 m, with rainfall of 800 mm. Water is supplied from the vast Lake Argyle, soils utilised for agriculture are predominantly black montmorillonitic clays and topography is generally very flat. Growing conditions are superb for most tropical crops. Out of a total of 11000 ha under irrigation, ...

The results of two field trials to determine the effect of ratoon stunting disease on the growth and yield of some widely grown and newly released sugarcane varieties are described. In the plant crop of a trial grown under full irrigation, the greatest reductions in yields of cane and sugar among six varieties, approximately 15%, occurred in N 14 and NC0376. In the first ratoon, the greatest re...

the present study was conducted with the objective of investigating the feasibility of using drainage water mixed with water to irrigate sugarcane (saccharum officinarum) in khuzestan province. the investigation was conducted in research center of sugarcane in farming seasons of years 2008-2009. four salinity levels of irrigation water were selected (s1, s2, s3 and s4 respectively with salinite...

The use of non-destructive devices like Delta-T-LeafAreaMeter and Canegro Models can help farmers to manage their cane crops and have an understanding of the importance of measurement of physiological parameters so as to maximize cane and sugar yields. This study was conducted on sandy clay loams of the lithosol group under the Zimbabwe soil classification system at The Zimbabwe Sugar Associati...

sugarcane is cultivated in extensive areas in khuzestan it is irrigated through hydro-flume and in furrows. for an evaluation of the effect of deficit- irrigation on sugarcane yield, this experiment was conducted. the treatments consisted of the conventional irrigation method (blank), variable, every other irrigation, (by alternative furrows) and invariable every other irrigation (by fixing the...
