Water scarcity is increasingly a global cause of concern mainly due to widespread changes in climate conditions and increased consumptive water use driven by the exponential increase in population growth.

Consumptive Water

As water scarcity worsens globally, there is growing interest in finding ways to reduce water consumption, and for reallocating water savings to other uses including environmental restoration. Because irrigated agriculture is responsible for more than 90% of all consumptive water use in water-scarce regions, much attention is being focused on opportunities to save water on irrigated farms. At the same time, many recent journal articles have expressed concern that claims of water-saving potential in irrigation systems lack technical credibility, or are at least exaggerated, due to failures to properly account for key elements of water budgets such as return flows. Critics have also asserted that opportunities for reallocating irrigation savings to other uses are limited because any freed-up water is taken up by other farmers. A comprehensive literature and internet survey was undertaken to identify well-documented studies of water-saving strategies in irrigated agriculture, as well as a review of case studies in which water savings have been successfully transferred to other uses. Our findings suggest that there is in fact considerable potential to reduce consumptive water use in irrigation systems when proper consideration is given to water budget accounting, and those savings can be beneficially reallocated to other purposes.

The increasing demand of Cassava for our dietary needs and shortage experienced going by the burgeoning global population is a cause for concern that require urgent attention. The study therefore considered the effect of some selected soil properties, nutrients, moisture content, yield and consumptive water use (CWU) on two selected Cassava varieties TMS 0581 and TME 419 respectively. The design was a Randomized Complete Block Design (RCBD) of four treatments and three replicates. Treatment A had fertigation, B used poultry manure, C employed NPK, 15-15-15 while D with no treatment was used as control. Soil properties such as Bulk Density (BD), Particle Density (PD), soil classification and nutrients such as Cation Exchange Capacity (CEC), Organic Matter (OM), Nitrogen (N), Potassium (K) and others were determined using standard procedures. Penman-Monteith (PM) model was used in estimating reference evapotranspiration (ETr) while its product with crop coefficient (Kc) produced crop evapotranspiration (ETc). Moisture content was measured at depths 10, 20 and 30 cm respectively while water use efficiency (WUE), irrigation water applied and tuber yield were also determined. The findings of this study showed that all the soil properties were within permissible levels to encourage optimum agronomic development of Cassava plant and the class was entirely a loamy soil which permits well-developed roottuber configuration. Tuber yields varied from 21.96 Kg to 25.13 Kg for TMS 0581 variety while TME 419 had 17.04 Kg to 31.63 Kg in all the treatments. Deficiencies were observed in some of the nutrients which were replenished with the introduction of the fertilizers among the plots. Moisture content at 30 cm depth is suggestive of adequate water availability sufficient enough to encourage proper tuber development for optimum yield while fertigation technique was adjudged the best as it improved Cassava Tuberization and WUE in all the treatments considered.
