Abstract:
The field experiments were conducted during the rainy (kharif) season of 2019 and 2020 at Meerut, Uttar Pradesh (INDIA), to evaluate the growth and productivity of basmati rice (Oryza sativa L.) as influenced by seedling density and iron and boron Biofortification. Three planting density, viz. 1 seedling/hill, 2 seedlings/hill and 3 seedlings/hill and five foliar application Iron and Boron (control, Fe @ 0.1% and B @ 0.04% at Maximum tillering stage, Fe @ 0.1% and B @ 0.04% at Panicle initiation stage, Fe @ 0.1% at Maximum tillering stage and B @ 0.04% at Panicle initiation stage and Fe @ 0.1% and B @ 0.04% at bothstages) were tested in a split-plot design (SPD), keeping as main and subplots, respectively, with 3 replications. The total rainfall receipt during the experimental period was 587.6 mm (10 rainy days) during 2019 and 369.6 mm (10 rainy days) during 2020. The experimental result revealed that different planting density and foliar application of Fe and B had a remarkable influence on the Growth, Yield and yield Attributes, and Profitability of rice. In general, among the 1 seedlings/hill had the highest Growth and yield Attributes which were statically superior over rest of the planting density during both the years. While in case of yield viz., grain, straw and harvest index, was highest in 3 seedling/hill. Of the different planting density, 3 seedlings/hill resulted in significantly the highest grain yield (5.02 and 5.11 t/ha) during 2019 and 2020, respectively. Among them, highest grain and straw yields were recorded with the treatment of 3 seedlings/hill and foliar spray of Fe @ 0.1% and B @0.04% at MT and PI.
