Abstract:
An experiment was conducted at Coastal Soil Salinity Research Station, NAU, Danti, during kharif season of 2020 and 2021 to study the effect of soil conditioners on nutrient uptake by kharif rice under coastal soils. The field experiment consisted of different treatments viz., T₁: Control without biocompost (BC) and gypsum (Gyp), T₂: Biocompost @ 10 t/ha, T₃: Gyp @ 50% GR, T₄: Gyp @ 50% GR + BC @ 10 t/ha, T₅: Gyp @ 75% GR, T₆: Gyp @ 75% GR + BC @ 10 t/ha, T₇: Gyp incubated BC @ 50% GR (BC @ 10t/ha) and T₈: Gyp incubated BC @ 75% GR (BC @ 10t/ha) were applied to kharif rice. These treatments were tested in randomized block design with three replications. The results revealed that the total nutrient uptake (grain and straw) by rice were recorded significantly higher with treatment T₈ (Gyp incubated BC @ 75% GR) followed by treatment T₇ (Gyp incubated BC @ 50% GR) during 2020, 2021 as well as in pooled results.
