ENHANCEMENT OF THE GROWTH AND YIELD OF RICE BY SPLIT APPLICATION OF PHOSPHORUS, POTASSIUM AND SULPHUR FERTILIZERS (Pages : 7 - 12)

A field experiment was conducted to investigate the effects of single and split applications of P, K and S fertilizers on the growth and yield of rice (cv. BRRI dhan29). Eight treatment combinations consisting of P, K and S fertilizers applied at different growth stages of rice crop. Split application of P, K and S fertilizers resulted significant increase in plant height, effective tillers, panicle length, filled grains and 1000-grain weight as well as grain and straw yields of rice. The highest grain (6.20 t/ha) and straw (7.75 t/ha) yields were produced by application of urea super granule (USG) at transplanting + 50% PKS at transplanting + 50% PKS at maximum tillering stage. PKS uptake by crop significantly increased due to the split application of fertilizers. Therefore, split application of P, K and S fertilizers along with USG exerted a beneficial effect on yield contributing characters, resulting in higher grain and straw yields of BRRI dhan29 in comparison to single application of those fertilizers during transplanting. The present study suggests that split application of PKS fertilizers along with USG-N might be recommended for profitable rice production in Bangladesh agriculture.Download
