Productivity and Profitability of Cotton-wheat Cropping System as Influenced by Complex Fertilizers

An experiment was conducted during 2012-13 and 2013-14 at Ludhiana, Punjab to find out the productivity and profitability of the cotton-wheat cropping system as influenced by complex fertilizers. The experiment was comprised of nine fertilizer treatments. The results demonstrated that significantly higher cotton yield and stalk yield was recorded under T9 -AP60+S15+Zn1.5 (15.3 q/ha and 50.5 q/ha respectively in 2012 and 22.2 q/ha and 55.6 respectively in 2013) which was statistically at par with T6 – DAP (P60)+S15+Zn1.5 (15.0 q/ ha and 50.4 q/ha respectively in 2012 and 22.1 q/ha and 55.4 q/ha, respectively in 2013). Similarly in wheat crop, T9 -AP60+S15+Zn1.5 gave significantly higher grain yield and straw yield (39.0 q/ha and 63.0 q/ha, respectively in 2012-13 and 45.6 q/ha and 73.6, respectively in 2013-14) which was comparable with T6 – DAP (P60)+S15+Zn1.5 (38.5 q/ ha and 62.8 q/ha respectively in 2012-13 and 44.4 q/ha and 72.4 q/ha in 2013-14) as compare to other treatments. Economic analysis indicated higher net return (₹ 8739.0) and B:C ratio (0.37) for cotton under T8- AP30+S7.5+Zn0.75 whereas T9 -AP60+S15+Zn1.5 net return (₹14417.5) and B:C ratio (1.07) for wheat as compare with other treatments.
