Abstract

In order to study the integrated effect of nitrogenand ORGANIC FERTILIZER on YIELD and YIELD components of Tarom cultivar of RICE a field experiment was carried out at the Haraz Technology Development and Extension Center in Mazandaran (Amol) during 2010. The experiment conducted as a randomized complete block design with 8 treatments and 3 replications. Treatments included two kinds of ORGANIC FERTILIZER (Bioll555) and Azola compost that every one of those was incorporated whit amount of nitrogen as: 1- without nitrogen 2- whit 50% N at basal 3- with 50% N (25% at basal and 25% at panicle initiation) and 4- with 100% N (50% at basal, 25% at tillering stage and 25% at panicle initiation). Other cultural practices were down to all plots according SRI method monotonously. In this study, plant height, panicle length, tillers and panicle number per hill, filled grains and total grains number per panicle, 1000 grain weight, economical and biological YIELD and harvest index were measured. Results showed that were not significant differences for grain YIELD among treatments, nevertheless the highest grain YIELD (4.491 t/ha) belonged to T8 (organic fertilizer Bioll555+100% Nitrogen (50% at basal+25% at tillering stage+25% at panicle initiation) and the lowest grain YIELD (3.673 t/ha) belonged to T1 (Azola compost without N application) which indicate N is very important in RICE production. For all measured traits, ORGANIC FERTILIZER (Bioll555) had superiority in comparison with Azola compost. We found that ORGANIC FERTILIZER is advantageous for decrease of N application up to 50%.
