Impact the Foliar Application by Potassium Silicate on Rice Seed Productivity of Cultivated Varieties (Oryza Sativa L.)

Abstract

Farm exploration was completed at Agriculture Research station in Kafr-Elsheikh governorate, Egypt, through 2022 and 2023. The main objective of investigation, enhancement the productivity of some rice cultivars in poor soil affected with drainage water by the foliar application potassium silicate at three rates, i.e., 2, 4 and 6g/L. Foliar use of Si at various rates altogether expanded every one of yield parts and yield t/ha as contrasted and untreated plants as control treatment during the two seasons. Between nine different traits were measured including morphological and yield components. Among concentrates of silicate potassium , apply silicate potassium at rate 6 g/ L recorded significantly higher grain yield and its component when compared control treatment during two seasons. Regarding to rice varieties, E. hybrid No.1 Sakha104 and Giza 178 recorded the desirable values for agronomic characteristics. The optimum combination which recorded the highest rice grain yield when E. hybrid No.1 and Giza 178 rice varieties foliated with magnesium silicate at 6g/L during growing seasons. So, could be suggested that, to get highest seed yield with drainage water should be cultivated Egyptian Hybrid1 or Giza 178 and Sakha 104 varieties under this investigation.
