Influence of seedling age and different levels and methods of application of nutrients on yield, nutrient content and uptake of rice (Oryza sativa L.)

A field experiment was conducted during the rainy (kharif) season of 2016 and 2017 at Dapoli, Maharashtra, to study the influence of different age of seedling age, levels and methods of fertilizers application on growth, yield, nutrients content, uptake and economics in rice (Oryza sativa L.). The result revealed that the 20-day-old seedling resulted in significantly highest grain and straw yield (tonnes/ha) as compared to 30-day and 40-day old seedlings. Among different levels of fertilizer application, 125% recommended doses of fertilizer (RDF) resulted in signifi cantly higher grain and straw yields followed by 100% RDF and 75% RDF in that descending order. Significantly higher value of grain and straw yields (tonnes/ha) were recorded in treatment split application of potassium with Zn, B and Cu spray (K4) followed by basal application of potassium with Zn, B and Cu spray (K3) which were at par and also significantly superior to all other treatments.
