SUMMARY

The suitability of PAU-LCC for N management in evolved Basmati rice (PB 1718) was evaluated at Research farm of KVK Panipat during kharif 2020. The investigation was carried out in a randomized block design with three replications and eleven treatments. The results of the experiment revealed that the yield and yield attributes like grain yield (4311 kg/ha), straw yield (6203 kg/ha), harvest index (43.11%) and number of tillers (246.7) was higher when nitrogen was applied according to recommended PAU-LCC band 4 (T3). Physiological parameters (Dry matter accumulation (DMA), CGR, RGR and chlorophyll content) were also affected by various nitrogen treatment, Highest mean values were recorded when N was applied as per PAU recommended LCC band 4 N management practice. The highest value of DMA (487.03 g/m2) was observed at harvesting stage. CGR was significantly higher (8.62 g/g/m2) at 100 DAT, maximum RGR (0.181 g/g/day) was recorded at 21 DAT and maximum chlorophyll content.
