- Abstract
In order to study the effect of biostimulants and growth regulator foliar application (PGRs) under different level of water stress, a field experiment was conducted to find out the role of some plant biostimulants and plant growth regulating substances on a rice cultivar grown under different irrigation intervals in the 2018 and 2019 growing seasons at the farm of Agricultural Research Station, Sakha, Kafrelsheikh, Egypt. The Experiment was conducted using Randomized Complete Block Design with Strip plot arrangements. Main plots consisted of the four irrigation intervals while sub plots contained the different plant biostimulants and plant growth regulators with different concentrations. Some growth characteristics, yield components were recorded. The main results indicated that spraying plant substances during this study increased all studied characters as compared to control treatment. Spraying with Crop plus surpassed and gave the highest value in all the studied characters followed by Cytokinin. Spraying Crop plus under irrigation every 12 days which cause water stress, relieve the harm of stress in the plant and increase the yield by about 2.47 t/ha as compared with control. These results are beneficial for farmers who suffer from shortage of irrigation water in their rice field.
