| Biostimulants are products that enhancement the fertilizers and elements use efficiency then increase plant growth, tolerant to water deficit and abiotic stresses. In small concentrations, these substances are efficient, favoring the good performance of the plant’s vital processes, and allowing high yields and good quality products. The present investigation was carried out in the experimental farm of Rice Research Department, FCRI, ARC, Egypt during 2019 and 2020 seasons. The objectives of this presentation, study the effect of growth promoter supplement on growth and agronomic traits and rice yield, as well as, relationship among grain yield and other studied traits with the different sources of growth promoter supplement for each studied varieties. Nine rice varieties were evaluated under three growth promoter supplement of foliar spraying of viusid agro, alfarid 1 and humic plus. A split-plot design in a randomized complete block arrangement was used with three replications. The main plots were devoted to growth promoter supplement While, sub plots were devoted to rice varieties. The remains cultural practices were applied as recommended by RRTC. Data were recorded on 25 plant/ m2 were taken from plot the following traits, as recommended by standard Evaluation System (SES) of IRRI. Results showed that, there were highly significantly between growth promoter supplement and rice varieties for all the studied traits, whereas, the desirable values recorded for yield and its component with viusid agro followed by alfarid 1, wherease, the lowest values recorded for yield and its component without application growth promoter supplement . Grain yield with treated by the viusid agro was significantly exceeded Control treatment by (23.09%). Yield increasing due to viusid agro was accompanied by significant increasing in number of panicles per plant (26.44%), 1000 grain weight (8.40%) compared with control treatment. This study concluded that, increasing rice grain yield and related traits were obvious for most studied varieties by applying the growth promoter supplement of viusid agro or alfarid 1 for the hybrids rice SK2034H and SK2003H under irrigation every eight days. | ||||
