| Popis: | A field experiment was conducted at Sindh Agriculture University Tandojam during the year 2015-16, aiming to investigate the response of turnip crop to various salinity levels of irrigation. The experiment was placed applying randomized complete block design (RCBD) with four different treatments i.e. Freshwater (I 1 ), EC w with 2.5, 3 and EC w 3.5 dS m -1 (I 2 , I 3 and I 4 ) respectively replicated thrice. The results for experiment placed revealed an average increase in soil EC e 0.09, 0.17, 0.26 and 0.38 dS m -1 under I 1 , I 2 , I 3 and I 4 respectively. An decrease in dry density (g cm -3 ) of soil profile, decrease in pH 0.19, 0.38, 0.5 and 0.84 in treatments I 1 , I 2 , I 3 and I 4 respectively and an decrease in agronomical data i.e. weight and diameter were also observed with an increase in EC w by the water being irrigated. Crop water productivity with 5.83, 4.35, 2.97 and 1.85 kg m -3 for treatmentsI 1 , I 2 , I 3 and I 4 respectively also decreased with an increase in EC w and Nacl. Average yield of 19.27, 14.37, 9.83 and 6.12 kg was obtained with applied treatments i.e. I 1 , I 2 , I 3 and I 4 respectively, thus a decrease in yield with 25.45%, 31.60% and 37.72% with treatments I 2 , I 3 and I 4 was observed when compared as treated by freshwater (I 1 ). Therefore farmers can use irrigation water having EC w 3.5 dS m -1 for the turnip crop at reduction of 37.72% (approximately). |
