Abstract

A field experiment was conducted on sandy loam soil at the college farm of Agricultural College, Naira, Srikakulam to study the yield attributes and Nutrient uptake of different rice varieties as influenced by the intervention of different agronomic management techniques under late sown, over aged seedlings conditions in a split-plot design, comprised of three different varieties MTU 1210 (M1), MTU 1224 (M2) and BPT 2411 (M3) transplanted at the age of 45 days in the main field as main plots and with subplot treatments of seven different agronomic techniques adopted for study i.e. comprised Planting 33 hills m-2 with 6 seedlings per hill + 100% RDN ( 120 kg N as 70:30 in 2 splits) (S1), Planting 44 hills m-2 with 3 seedlings per hill + 100% RDN (S2), Planting 44 hills m-2 with 6 seedlings per hill + 100% RDN (S3), Planting 33 hills-2 with 6 seedlings per hill+125% of RDN (150 kg N as 70:30 in 2 splits) (S4), Planting 44 hills m-2 with 3 seedlings + 125% of RDN (S5), Planting 44 hills m-2 with 6 seedlings per hill + 125% of RDN (S6). Planting 33 hills m-2 with 3 seedlings per hill + 100% RDN (S7). Regarding yield attributes and Nutrient uptake, BPT 2411 outperformed MTU 1224 and MTU 1210 among the varieties. Under late sown over aged seedlings conditions the variety BPT 2411 cultivated with an agronomic management of planting 44 hills m-2 with 6 seedlings per hill + 125% of RDN of fertility levels of 150-60-50 N, P and K kg ha-1 attains the highest grain and straw yields.
