2007
Zahid, T.M.
The present investigations were made to see the effect yield of maize hybrid (Zea mays L.). The research was conducted on a sandy loam soil. Experiment was laid out in Randomized Complete Block Design with a net plot size of 5x3 m. Different levels of NPK were 0-0-0 (F1), 100-50-25 (F2), 150-50-50 (F3), 200-100-75 (F4), 250-100-100 (F5), 300-150-125 (F6), 350-150-150 (F7), kg per ha was used as of source of trial. The crop was sown on well prepared seed bed keeping R x R distance 60 cm and P x P distance at 23 cm. The whole of the phosphorus and potash along with half of nitrogen fertilizers in form of DAP, sulphate of potash and urea respectively, were applied at sowing and the remaining amount of nitrogen fertilizer was applied at first irrigation. All other cultural practices were kept normal and uniform in all the treatments. The data shows that Cob length was significantly affected by the variable rates of NPK and treatment F5 (250-100-100) and F6 (300-150-125) produce
