Abstract:
A field experiment was conducted with calcareous sandy loam soil of Pusa (water management field of R.A.U.) taking potato var. Rajendra Alu-3 as test crop to study the effect of potassium and irrigation on growth parameters, yield, K-uptake, quality parameters and water use efficiency.The starch content of potato tuber varied from 11.1 to 18.1% in the year 2005-06. Increasing levels of irrigation upto I4 significantly increased starch content from 13.38 (I1) to 16.22% (I4). Likewise, starch content also increased significantly from 12.58% in K0 to 17.05% in K4 with increasing levels of K2O application .Similar trend of data on starch content in potato tuber was found in second year (2006-07) of experimentation in which starch content ranged between 10.97 and 18.44%. Interaction between K and irrigation levels was found non-significant in both the years of experimentation.
