GROWTH AND YIELD RESPONSE OF MAIZE TO INTEGRATED USE OF GLIRICIDIA SEPIUM, FARM MANURE AND NPK FERTILIZERS

Abstract

A field study was carried out to evaluate the effect of some organic fertilizers such as Gliricidia sepium, farm manure and inorganic fertilizers like NPK applied alone and in different combinations on the growth and yield attributes of maize (Zea mays L.) at Coastal Agricultural Research Station, PARC, Karachi, during the year 2007-08. The experimental design was randomized complete blocks, replicated four times having eight fertilizer treatments, including control. All the organic fertilizers were applied at the time of land preparation. Results obtained showed that application of NPK combined with organic fertilizers helped in increasing the crop yield more than when fertilizers were applied separately.
