Abstract
A field experiment carried out at Research farm, Vivekananda Global University, Jaipur during rabi session 2025-26. The treatments comprising four irrigation levels (I1: no irrigation, I2: one irrigation at CRI, I3: two irrigation at CRI and booting stage and I4: three irrigation at CRI, booting and milking stage) and four silicon levels (S1: control, S2: 100 kg ha-1, S3: 150 kg ha-1 and S4: 200 kg ha-1), assigned respectively to main and sub plots and those were replicated three times in split plot design. Results revealed that under three irrigations crop obtained highest value of growth parameters (plant height, dry matter accumulation, total tillers, flag leaf area, days to 50 per cent heading and days to 50 per cent maturity) and yield attributes viz., effective tillers, grains ear-1, weight of grains ear-1, ear length and test weight as compared to other irrigation levels. However, the maximum crop growth rate between 50 to 75 DAS under one irrigation and between 75 DAS to at harvest under two irrigations however, highest relative growth rate was recorded under no irrigation. Superior performance of growth and yield attributes with three irrigations resulted in significant increased in grain, straw, biological yield and harvest index. Application of silicon 200 kg ha-1 significantly increased growth parameters viz., plant height, dry matter accumulation, total tillers, crop growth rate, flag leaf area, days to 50 per cent heading and days to 50 per cent maturity and yield attributes i.e., effective tillers, grains ear-1, weight of grains ear-1, ear length and test weight as compared to remaining silicon levels. The maximum grain, straw, biological yield and harvest index were obtained under silicon application 200 kg ha-1 resulted in highest.
