ABSTRACT
Two field experiments were conducted at Shalimar Campus of Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir during 2012 and 2013 under irrigated and un-irrigated mulched conditions with the objective to study the growth and yield of maize at different planting dates and planting density and to simulate trends of maize production. Experiment was laid in split-plot design assigning four planting dates 15th April (D1), 30th April (D2), 15th May (D3) and 30th May (D4) to main plots and three planting density 50cm×20cm (S1), 60cm×20cm (S2) and 70cm×20cm (S3) to sub-plots. The planting date 15th April (D1) produced highest yield of 50.60 and 53.81 q ha-1 under irrigated conditions and 43.59 and 45.28 q ha-1 under un-irrigated mulched conditions during 2012 and 2013, respectively. Among planting density 60cm×20cm (S2) recorded highest grain yield of 42.32 and 44.72 q ha-1 under irrigated conditions and 36.63 and 38.53 q ha-1 under un-irrigated mulched conditions during 2012 and 2013, respectively. Under irrigated conditions highest net return (US$. 87170), gross return (US$. 1810), and B: C ratio (2.18) was observed with treatment combinations of 15th April (DI) with 60cm×20cm (S2). The next best treatment combination was 15th April (DI) with 50cm×20cm (S1) with net return (US$. 1239), gross return (US$. 1804) and B: C ratio was 2.17. Un-irrigated mulched condition influenced the cost of production, gross return, net return and B: C ratio of crop. Highest net return (US$. 852), gross return (US$. 1586), and B: C ratio (1.16) was observed with treatment combinations of 15th April (D1) with 60cm×20cm (S2).
Key words: Temperate Kashmir, US$, Planting dates, Planting density, Yield, Economics, B:C ratio.
