“…A sub sample of ten plants was taken for determining the yield components (number of pods per plant, number of seeds per pod and the 100 seeds weight). Crop water productivity is commonly expressed as the economic yield divided by the seasonal crop water use (seasonal evapotranspiration) [10] [11], while the Irrigation water productivity is the economic yield divided by the total irrigation water applied [12]- [27].…”

“…Quantitative information on WP is, therefore, necessary for effective planning of irrigation water management strategies in an area [9]. Crop water productivity (CWP) is generally defined as marketable yield (Y) to the volume of water consumed by the crop (ET) [10] [11], but economists and farmers are most concerned about the yield per unit of irrigation water applied [12].…”

A field experiment was conducted at Hudeiba Research Station Farm, located at Ed-Damer, Sudan during 2011/2012 and 2012/2013 winter seasons to investigate the effect of different irrigation regimes and varieties on chickpea (Cicer arietinum L.) yield, yield components and water productivity. The treatments include three irrigation regimes; irrigation every 10 days (I 1 = full irrigation), irrigation every 15 days (I 2 = moderate stress) and irrigation every 20 days (I 3 = severe stress) and two varieties (Borgieg and Wad Hamid). The treatments were arranged in factorial randomized complete block design (RCBD) with 3 replications. Irrigation water being applied, grain yield, yield components (number of pods per plant, number of seeds per pod and the 100 seeds weight) and crop water productivity (CWP) and irrigation water productivity (IWP) were recorded. Results showed that the number of pods per plant, number of seeds per pod, 100-seeds weight, grain yield and irrigation water applied were significantly (p ≤ 0.001) affected by irrigation regimes. The highest values of these traits obtained with full irrigation, whereas the lowest values were recorded under severe water stress conditions. Results also indicated that, moderate and severe water stress regimes saved irrigation water by 24% and 32%, respectively compared with full irrigation. This study indicated that treatment I1 which was irrigated every 10-days did * Corresponding author. M. K. Alla Jabow et al.1300 not produce the highest IWP, while treatment I 2 which irrigated every 15-days gave the highest IWP. The lowest IWP occurred at severe water stress regime (I 3 ). It could be concluded that moderate water stress might be adopted. Contrarily, the adoption of severe water stressed that produce high water savings would lead to yield losses that might be economically not acceptable. The late maturing chickpea variety of Borgieg significantly (p ≤ 0.05) out-yielded the early maturing variety Wad Hamid by 11%. Borgieg displayed the highest values of CWP and IWP.

This paper is a follow up from the first paper which described the SALTMED model. In this paper the focus is on the model application using data of tomato and potato from field experiments in Italy, Greece (Crete) and Serbia. Drip full irrigation, drip deficit irrigation, drip as partial root drying (PRD), sprinkler and furrow irrigation were used in three years experiment between 2006 and 2008.In drip irrigated experiments, the drip line was 10 to 12 cm below the surface. Dry matter, final yield, soil moisture and soil nitrogen were successfully simulated. The study showed that there is a great potential for saving water when using subsurface drip, PRD or drip deficit irrigation compared with sprinkler and furrow irrigation. Depending on the crop and irrigation system, the amount of fresh water that can be saved could vary between 14 to 44%. PRD and deficit drip irrigation have proved to be the most efficient water application strategies with the highest water productivity.

Water productivity for Boro Rice production: study on floodplain Beels in Rajshahi, Bangladesh

et al. 2015

View full text Add to dashboard Cite

Context: Water productivity is considered as an important indicator of Agriculture productivity because of the scarcity of freshwater. More yield or output against same or less amount of water has become the global interest. Objectives: This study measures the productivity of water on the floodplain land in terms of Boro rice cultivation for two floodplain beels in Rajshahi Bangladesh. Materials & Methods:For this study, the production and market price data were collected by direct observation based on 30 samples in the year 2006-07. Results: This study found gross water productivity of rice yield as 0.47 kg m -3 in beel Mail and 0.43 kg m -3 in beel Chandpur. In monetary value, water productivity per cubic meter irrigation water were TK 5.65, TK 3.42 and TK 2.64 based on gross return, net return considering cash costs and net return considering full costs in beel Mail. In beel Chandpur these values were TK 5.19 m -3 , TK 2.87 m -3 and TK 2.14 m -3 , respectively. The usage of average irrigated water in the boro rice farms were estimated 10730.05 m -3 and 11236 m -3 with an average production of yield 4992.95 kg and 4783.20 kg in beel Mail and beel Chandpur. Statistical result shows that keeping irrigation water constant, a 1% increase of boro rice yield will increase water productivity at 0.916% in beel Mail and 0.972% in beel Chandpur. The water productivity in beel Mail was 4.65% higher than beel Chandpur due to the intervention of community based fish culture management. Conclusion: The findings of this study will help to govern and improve production by proper utilizing floodplain lands.
