Investigation of the Effect of Different Planting Methods

This study was conducted as a split-split plot experiment based on a randomized complete block design with three replications in Khuzestan Province, aiming to determine the most suitable rice cultivation method over two consecutive years. This study was designed and conducted to achieve the following objectives:1-To enhance rice production under different cultivation methods subjected to salinity stress and evaluate the effects of various levels of growth hormone.2-To assess the individual and combined effects of growth hormones on the photo biochemical characteristics of rice plants.3-To investigate the influence of hormonal treatment timing on plant growth, adaptation, and tolerance to salinity stress.4-To study the effects of different methods of hormone application on vegetative and reproductive growth of rice, considering the two-way and three-way interactions among hormones, and planting methods under saline conditions.5-To determine the impact of hormone type on vegetative and reproductive development of rice.6-To evaluate the yield potential of different rice genotypes under salinity stress.7-To improve water-use efficiency in rice cultivation.
