Abstract

To evaluate IRRIGATION and Azolla compost on agronomic traits of rice in Gilan province, an experiment was carried out in Rice Research Institute of Iran, Rasht during 2009. The experiment was arranged in a randomized complete block design as split-plot with three replications. In this experiment, three IRRIGATION management levels (I1=100% control and I2, I3, respectively, IRRIGATION with 80%, 60% evaporation from a class A evaporation pan) as the main plot and different amounts of COMPOSTED AZOLLA at four levels (C1 C2, C3 and C4, respectively, without the use of compost, 4 tons, 8 tons and 12 ton/ha) respectively as Sub plot. The result showed that the effect of different levels of IRRIGATION water on grain yield, plant height, number of seeds in hollow clusters and total biomass is significant and the effect of different doses of compost on grain yield, height, tiller number, panicle number, panicle length, number of grains per panicle, filled grain number, hollow, emptiness percent, cluster weight, total biomass, yield and chlorophyll is significant. Interactions effect IRRIGATION and compost on yield was significant. In general, it could be concluded that appropriate management in paddy fields, IRRIGATION, 60 percent of the amount of evaporation from class A PAN EVAPORATION with the use of 8 ton/ha is Azolla compost.
