Abstract
Growth and N, P, K uptake of Acala SJ-2 cotton (Gossypium hirsutum) were investigated in an irrigated permanent-plot field (Typic chromoxerert) at Bet Dagan, Israel, under semi-arid conditions using different nitrogen levels: 0, 60, 120, 180 and 240 kg N ha−1. The total dry matter accumulation at these levels was 9.0, 10.7, 15.1, 17.1 and 15.6 ton ha−1, respectively. The uptake of N, P and K was 110, 144, 267, 322 and 301 kg N ha−1∶31, 34, 46, 44 and 38 kg P ha−1; and 120, 151, 208, 251 and 230 kg K ha−1, respectively.
