A field experiment was conducted to evaluate the influence of limited and adequate irrigation and moisture conservation practices (rice straw mulch and hydrogel) on yield and water use efficiency in wheat. Though, maximum wheat yield (3.92 t/ha) and water use efficiency (15.72 kg/ha/mm) was recorded with four irrigations at crown root initiation stage, tillering, late jointing, and milk stage, two irrigations applied at tillering and flowering and soil mix drilling of 7.5 kg/ha hydrogel (a synthetic polymer) at sowing produced comparable yield (3.34 t/ha) with less water use, enhancing the water use efficiency (15.45 kg/ha-mm). The higher net return and B : C ratio were found in the treatment 2.5 kg/ha hydrogel. Thus, from present study it may be concluded that under limited irrigation conditions, water conservation practices like soil mix drilling of hydrogel and rice-straw mulching are beneficial for maintaining optimum moisture in soil to enhance wheat yield and water use efficiency.

Yield Responses

A comprehensive study was conducted over a 4-year period (1984–87) to evaluate the water use, growth and yield responses of pearl millet (Pennisetum glaucum (L.) R. Br.) cv. CIVT grown with and without fertilizer (30 kg P2O5 and 45 kg N ha−1) at the ICRISAT Sahelian Centre, Sadoré, Niger. Our study showed significant year and fertilizer effects on the growth and yield of millet at the study site. Observed year effects were primarily due to the variations in the amount and distribution of rainfall in relation to the potential demand for water. During 1984, 1985 and 1987, total rainfall was below the long term average, while in 1986 it was above average. While the onset of rains (relative to the average date of onset) was early from 1984 to 1986, in 1987 the sowings were delayed by as much as 33 days. Of all the four years, the separation between the treatments in the cumulative evaporation is most evident for 1984, which was a drought year with below-average rainfall in all the months from June to September. Cumulative evaporation patterns in 1985 and 1986 were similar because of regular rains and high average rainfall per rainy day from June to October. In 1987, sowings were delayed until 15 July and only 6·9 mm of rainfall was received per rainy day in July. Hence cumulative evaporation was initially low and showed a significant increase only after two significant rain events in early August. There was a large response to fertilizer in all the years as small additions of fertilizer phosphate increased the soluble phosphate in the soil. Fertilizer application resulted in a small increase in water use (7–14%) in all years except 1987. Increased yield due to the application of fertilizer was accompanied by an increase in the water-use efficiency (WUE) in all the four years with the largest increase in 1985. The beneficial effect of fertilizers could be attributed to the rapid early growth of leaves which can contribute to reduction of soil evaporative losses and increased WUE. Over the four seasons, average increase in the WUE due to the addition of fertilizer was 84%.

Method Of Planting

The main aim of land configurations is in situ conservation of soil moisture by increasing the opportunity time for augmented water use efficiency and drain out excess water. The field study was conducted for two years under rainfed conditions of Dharwad on residual soil moisture and fertility. Cowpea produced higher grain yield (13.4 q ha-1), haulm yield (25.6 q ha-1) and harvest index (34.4 %) with Broad Bed and Furrow (BBF) method of planting. Similarly, BBF method resulted in higher soil moisture content (32.09 % at 40 DAS) and rain water use efficiency (RWUE) of 5.96 kg ha-mm-1. The RWUE had a significant and highly positive correlation with soil moisture at 40 and 55 DAS (with r value of r=0.94** and r=0.96**, respectively). BBF method of planting also registered higher gross return (Rs.42725 ha-1), net return (¹ 27515 ha-1) and benefit-cost ratio (2.82). Cowpea can be grown successfully after summer maize on existing BBF configuration for higher yield and rain water use efficiency.

Water Use Rates

Irrigation of residential lawns represents one of the major uses of potable water in many regions. An increased understanding of physiological responses underlying effects of turfgrass genotypes and management practices on water use rates and water use efficiencies could contribute to water conservation. Thus, we evaluated the effects of nitrogen (N) fertilization (0.0 and 2.5 g·m−2) and light environment (full sun and 50% shade) on average daily evapotranspiration (ETAVE), daily ET per unit leaf area (ETLA), carbon exchange rate (CER), and water use efficiency (WUE) in upright (experimental TAES 5343-22) and prostrate (‘Empire’) zoysiagrasses (Zoysia japonica Steud.) during two repeated trials. Across all treatments, ETAVE was 4.0 and 5.4 mm·d−1 during Trials 1 and 2, respectively. In the upright-growing genotype, ETAVE was ≈10% greater than the prostrate genotype during Trial 1. Nitrogen fertilization increased water use by ≈20% compared with non-fertilized pots. However, N fertilization reduced ETLA and increased WUE. Thus, ETAVE was positively related with WUE. As a result, there was a tradeoff between ETAVE and WUE, indicating that efforts to achieve reductions in water use through low N fertilization or genotypes can be accomplished, but in some cases at the expense of using water less efficiently to assimilate carbon for plant growth processes. In turfgrass, reductions in growth and WUE might be acceptable to minimize water use, but vigor and quality need to be maintained.
