Performance evaluation of Border irrigation method for cotton field

Abstract

Performance evaluation of Border irrigation method was carried out for cotton field in village Kirarkot, Sirsa (Haryana). Water application, storage and distribution efficiency were estimated using measurements of soil moisture (%), infiltration rate (cm/hr), water advance and recession time (minute) during different irrigation events. The advance time increased during the growing season due to increased infiltration rate and increased resistance to flow by the growing crops. The water application efficiency of cotton field was 100 per cent as average applied depth (8.26 cm for canal irrigation and 9.06 cm for tubewell irrigation) of irrigation was less than the average required depth (10.30 cm for canal irrigation and 10.98 cm for tubewell irrigation) throughout the field plots. The observed water storage efficiency in different cotton fields varied from 72.92 -90.08 per cent indicating under irrigation. Water distribution efficiency of cotton fields (97.8 -99.2per cent) indicated a relatively high degree of uniformity of water application. Stratified soil profile (sandy loam: 0-30 cm and sandy clay loam: 30-120 cm) of the selected fields reduced the infiltration rate to relatively very low value after 10-15 minutes creating favourable condition for uniformity of water application under border irrigation.

Soil water dynamics and yield response of broccoli (Brassica oleracea) under drip irrigation with different irrigation frequency

“…The drip irrigation system typically improves crop yield by 25-30% and saves irrigation water up to 50% relative to traditional irrigation methods (Priya et al 2017, Singh et al 2022. Drip systems not only save irrigation water, but also provide the best management of nutrients applied to the crop (Singh et al 2018). Earlier studies have shown that drip irrigation is the most appropriate method of irrigation, particularly in vegetable crops, which increases the production and enhances the water use efficiency (Thompson et al 2002).…”
