Seedling root dip in phosphorus and micronutrient treatment in lowland rice based cropping system in Lawngtlai district Mizoram

A field experiment has been conducted with high yielding variety of rice (cv RCM 6) during 2023-24 kharif season to determine impact of Phosphorus (P) treatment in association with vermicompost and seedling root dip in PSB on length of root at 30 and 45 day after transplanting, height of the plant, number of tiller per hill at 30, 45, 60 DAT and at harvest including seed yield. The experiment was carried out at Sihtlangpui, Krishi Vigyan Kendra Farm, Lawngtlai district, Mizoram. The height of the crop was significantly higher as 72.6, 112.3, 145.6 and 144.6 cm at 30, 45, 60 days after transplant and at harvest respectively in T3 over control and T2. The same trend was seen in number of tillers per hill. The length of the root also increased significantly from control at 30 and 45 DAT. The highest yield (4.9 t/ha) was observed in T3- Seedling root dip + Vermicompost + RDF which was significantly higher over control. It was evident that dipping the seedling root in Phosphorus Solubilizing Bacteria (500ml/L) mixed well with 5kg compost incorporated with recommended dose of fertilizer (80:60:40 NPK/ha) and vermicompost (10t/ha) during land preparation resulted in highest yield and could be recommended to farmers to augment the yield of lowland rice in Lawngtlai distict.
