Field trials were carried out at Uswo location, located in North Rift part of Kenya during March 2016-July 2016 growing seasons. The main objective was to determine the yield and quality responses of potato crop to deficit irrigation (DI) and mulch. Experimental set up was a randomized complete block design (RCBD) with three replicates. In the study, five water levels of drip irrigation (100%ETc, 90%ETc, 80%ETc, 60%ETc and 50%ETc) with and without mulch were considered. The 100%ETc was used as an experimental control. Deficit irrigation was carried out at different growth stages of the plant for the remaining plots. The plots were covered during a rain event with a polythene sheet as a shelter and unrolled when there was no rain. Results revealed that plots with mulches at 100%ETc attained 50% plant emergence earlier than those without mulches. Also highest plant heights, stems per plant and better tuber qualities were achieved in the mulched plots under 100%ETc. Water use efficiency (WUE) increased as the irrigation water was reduced. Tuber yields ranged from 16.2±0.6 t ha-1to 29.5±0.9t ha-1and 14.3±0.5 t ha-1to 27.3±0.5 t ha-1for mulch and non-mulch treatments respectively.WUE ranged from 33.6 to 59.8 kg/ha/mm and 30.8 kg/ha/mm to 53.4 kg/ha/mm for mulch (M) and non-mulch (NM)respectively.Optimal crop production was obtained at 80%ETc with WUE of 40.1 kg/ha/mm and 36.9 kg/ha/mm for mulch and non-mulch respectively. Therefore optimal crop production with minimum water use is recommended for practice in farms with scarce water resources. |
