Effect of mulch and irrigation on tuber size, canopy temperature, water use and yield of potato (Solortum tuberosum)

Type: article
Abstract: A field experiment was conducted during 3 spring seasons (Februawune) for 1995 97 on sandy loam soil, to study the effect of irrigation levels in conjunction with pine needle mulch on potato (Solanum tuberosum L.). Pine needle mulch increased the tuber yield by 35% over no mulch. The yield increased significantly up to IW:CPE 1.50, except during 1997, which received a good rainfall (236.3 mm). The mean effect of mulch was equivalent to 1 irrigation (5 cm) in terms of potato yield advantage. Mulch and irrigation treatments produced more large size ( 50 mm) tubers compared to no mulch and rainfed treatment respectively. The water use efficiency (WUE) was more (39.9%) with mulch over no mulch. All irrigation treatments had more WUE than rainfed (678 kglha cm), being the maximum with stolonization stage irrigation treatment (830 kglha cm). The canopy temperature was 25 2.5OC In IW:CPE 1.50, which recorded the highest tuber yield.
