EFFECT OF NAPHTHALENE ACETIC ACID AND DIFFERENT PHOSPHORUS LEVELS ON PANICLES, SPIKELETS, STERILITY, NORMAL KERNEL, YIELD AND BENEFIT COST RATIO OF RICE - I. Bakhsh; I. U. Awan; M. Niamatullah; K. U. Zaman; S. Ramzan; E. A. Khan (Journal of Animal and Plant Sciences, 2012)
Growth and yield attributes of rice were evaluated with the application of varying doses of Naphthalene Acetic Acid (NAA) and Phosphorus during 2004 and 2005. The experiment was laid out in Randomized Complete Block (RCB) Design with split-plot arrangements and replicated four times. Main plots were assigned to four levels (0, 60, 90 and 120 ml ha-1) of NAA. Results revealed that NAA @ 90 ml ha-1 and phosphorus application up to 100 kg ha-1 boosted up the rice productivity due to maximum value recorded in terms of panicles m-2 (347.5 and 349.5), spikelets panicle-1 (153.3 and 153.8), sterility (22.25 and 19.94 %), normal kernel (77.25 and 78.69 %), paddy yield (7.62 and 7.82 t ha-1) and net income (Rs. 30986 and 32236 ha-1) with BCR of 1.64 and 1.70 indicating the economical yield of rice during 2004 and 2005.
