Effect of organic-inorganic mixed fertilizers on the growth and yield of rice (Oryza sativa L.cv. Al-Yasamin)


A field experiment conducted at Al-Ahamer district, Al-Najaf during summer season of 2013on clay loam soil. The aim was to investigate the effect of the addition of suggested organic-inorganic mixed fertilizer on growth and yield of rice (Oryza sativa L.),cv.Yasamin. Experiment was done as Completely Randomized Block Design with three replicates. Results showed that the addition of organic-inorganic mixed fertilizers (Perl humus +NPK, Open green+ Diammonium phosphate (DAP) +Foliar application, K2SO4), significantly increased plant height (26%), panicle number per square meter (97%), biological yield (44%), grain yield (26%), panicle length (14%), grain number per panicle (06%), 1000 grain weight (52%) and harvest index (55%), in comparison with the Conventional farming using chemical fertilizers (Diammonium phosphate, DAP+ Urea+ nitrogen–phosphorus (NP)).
