Abstract

In field trials conducted on red sandy loam soils (Alfisols) of Bangalore, high frequency irrigation given in smaller quantities (20 mm at 1.00 IW/CPE) was useful to get higher uptake of nitrogen (116.6 kg/ha), phosphorus (16.75 kg/ha) and potassium (169.7 kg/ha) which in turn influenced the tuber yield of potato (cv. Kufri Jyoti). Polythene mulch was superior in tuber yield (182.2 q/ha) and uptake of nutrients (103.2, 13.97 and 156.2 kg/ha of N, P and K, respectively) when compared to no mulching.
