Title

MODELING RESPONSE OF HASHEMI RICE VARIETY TO CHANGE IN SALINITY LEVELS DURING THE GROWTH STAGES

Pages

  168-176

Abstract

 Population growth and decreases water availability led to decreases water resources and consequently decreasing in the water portion of agricultural sector.So researchers in this condition have to find new solutions for utilization of low quality water in agriculture.This research was performed in order to assess the possibility of saline water use in Hashemi RICE production, RICE yield estimation using PRODUCTION FUNCTION and Find the best time to use these waters in RICE Research Institute during 2010 crop season.Plan was in pot cultivation under shelter with factorial arrangement in a randomized complete block design in4 levels of water SALINITY i.e.2, 4, 6, and 8 dsm1-that were applied at 4 different growth stages i.e.tillering, panicle forming, heading and ripening.Saline water was made by using NaCl+CaSO4 (2: 1). Results showed that the effect of different levels of SALINITY and different growth stages on yield was significant. Applied SALINITY levels, respectively represented 21, 25, 37 and 47 percent yield losses. The panicle formation and tillering stages with 1.92 and 2.41 T5 on per Hectare of yield were the most sensitive stages to SALINITY. There was positive correlation between Grain yield and Panicle weight, 1000-grain weight and panicle length but negatively correlated with the Percentage of emptiness per panicle. According to results it is possible to predict RICE PRODUCTION FUNCTION under conditions of SALINITY at different growth stages using Panicle weight, Percentage of emptiness and number of tillers, can predicted.
