Field experiment was carried out during the spring and fall seasons of 2019 at the Abu Ghraib Research Station of the Agricultural Research Office/ Ministry of Agriculture, was aimed to investigate the effect of plant growth inhibitors on growth and yield of several sorghum varieties .Randomized Complete Block Design within split plot arrangement with three replications was used. The main plot consists of three growth inhibitors (Cycocel, Ethiphon, and Mebiquat), which were added at stages six and eight leaf stage, in addition to the control treatment (distilled water only), the sub plot was included three cultivars (Mabrouk, Buhooth 70 and Giza 113). The results showed in both seasons significant interaction between cultivars and growth inhibitors in most of the studied traits. The plants of the variety Giza 113 sprayed with Ethiphon recorded the lowest period of reaching physiological maturity, the highest average dry matter yield, and the highest weight of 1000 grains (89.00 days, 17.32 ton ha-1, and 39.33 gm) respectively. The same variety recorded the highest content of chlorophyll in the leaves and the highest grain yield due to the effect of Mebiquat (49.50 spad, 3.93 ton ha-1. The cultivar Buhooth 70 with the effect of Cycocel achieved the highest average of dry matter yield of 33.27 ton ha-1.

Plant Growth Inhibitors

The commercial development of a wide variety of synthetic plant growth inhibitors for use in floriculture has been possible for several reasons. The high cash value of flower crops can absorb relatively costly treatments; specificity of response permits the viability of several products of basically similar properties, and restrictions on use are less stringent than they would be for food crops. Nevertheless, there are some important applications in temperate cereals and tobacco.

The specificity of the action of antigibberelin drugs is that they can influence the processes and intensity that cannot be corrected by agronomic measures of cultivation. The purpose of the work was to scientifically substantiate the use of plant growth inhibitors with an antigibberelin type of action as an element of soybean cultivation technology, to identify their effect on growth, development and productivity. The research was carried out on a soybean plants of the Triada variety. At a height of shoots 10-15 cm plants were treated with aqueous solutions: 0.5% tebuconazole, 0.2% ethephon and 0.5% chlormequat chloride until complete wetting of the leaves. Control plants were treated with water. During the research, morphological parameters, leaf surface area, and organ mass were defined. It was established that the use of plant growth inhibitors with an antigibberelinic mechanism of action (the ethylene producer esfone (0,2 %), the triazole-derived retardant tebuconazole (0,5 %) and the onium preparation chlormequat chloride (0,5 %) on soybean plants led to morphological and anatomical changes: decreasing of the mass of leaves and stem, increasing the thickness of the stem and root collar. The preparations reduced the length of internodes of soybean plants,, that created the preconditions for plant resistance to lodging. Plant growth inhibitors had different effects on the leaf surface area of soybean plants: there was an increase in this indicator by 24% for the use of chlormequat chloride, and processing with esfon and tebuconazole led to a decrease of 26% and 23% accordingly. Different effects of retardants were found on the length of the main root. Under the action of esfon the length of the main root decreased by 20%; the application of both chlormequatchloride and tebuconazole, this indication increased accordingly by 43% and 37%. The question of studying the influence of modern plant growth regulators with a different mechanism of action on the productivity of different varieties of legumes remains relevant
