Abstract:

Present study was conducted at Pakistan Agriculture Research Council (PARC) Farm, Kala Shah Kaku in 2014. Rice seedlings were transplanted in different planting geometries with line to line and plant to plant distances of 25×10, 30×10, 20×15, 25×15, 20×20, 30×15, 25×20 22.5×22.5 and 25×25 cm in randomized complete block design (RCBD) with three replications. Results revealed higher number of tillers with closer plant spacing that ultimately exhibited greater number of panicles (309.3 to 275.5 m-2) in plant spacing ranging from 25×10 to 30x15 cm. Higher paddy yields (3.81 to 3.61 t ha-1) and straw yields (14.8 to 13.5 t ha-1) were also recorded from the same treatments (25×10 to 20×20 cm). The highest net benefit (Rs.105149.72 ha-1) was recorded in 20×20 cm spacing treatment while the lowest (Rs.90614.55 ha-1) was achieved from the widest spacing (25x25 cm) treatment. The maximum net benefit and a viable marginal rate of return (102%) was observed from 20×20 cm plant spacing. It can be concluded from results that Basmati 515 should be transplanted in a planting geometry of 20×20 cm to achieve the maximum grain yield with higher economic returns.
