Abstract
Two field experiments were conducted during 2022 and 2023 seasons to assess the impact of magnesium silicate on growth, yield and its components of three rice varieties under both environmental normal condition (6 days) and water deficit (12 days) during two seasons at the farm of Rice Research and Training Center, Sakha Agricultural Research station, Kafr El-Sheikh Egypt, Strip - split plot in randomized complete block design with three replications was used. The horizontal plots were irrigation treatments and the vertical plots were located for levels of silicon (Si 0, Si 2000, Si 4000 and Si 6000) ppm, while rice varieties namely; Sakha108, Sakha 109 and Giza 179 were assigned in sub–subplots. Eight different traits were measured including morphological and yield components. Among irrigation treatments, the irrigation every four days (normal condition) recorded significantly higher grain yield and its component when compared to water deficit treatment during two seasons. Effect of the concentrates of silicate application on growth, grain yield and its components, the maximum grain yield was achieved from the application of Si 6000 ppm. Regarding to rice varieties, Sakha 108 and Giza 179 recorded the desirable values for agronomic characteristics. The optimum combination which recorded the highest rice grain yield when Sakha 108 and Giza 179 rice varieties foliated with magnesium silicate at 6000 ppm when irrigated every 6 days in normal irrigation condition during growing seasons, Hence the results showed that the higher concentrate of magnesium silicate enhanced the productivity of rice varieties under irrigation every 6 days, silicon use efficiency was higher at lower concentrations. Also, results could be concluded that, irrigation every 12 days for either Giza 179 or Sakha 108 rice varieties which gave the great grain yield and reached to 8.240 and 8.100 ton/ha respectively with an average of 8.170 ton/ha and grain yield reduction 22.43%, the total water used were 10520 and 11775 m3/ha average of11147.5 m3/ha with average of water saved 1221 m3/ha.
