Effect of nitrogen, phosphorus, potassium and sulphur on the yield of mango

The experiment was conducted at the research field of Regional Horticulture Research Station, Chapai Nawabganj during 2010-11, 2011-12 and 2012-13 to find out the proper combination of fertilizer nutrients (N, P, K and S) in presence of organic manure for obtaining higher yield of mango (var. BARI Aam-1). The treatments were native nutrient i.e. control (T1), N360P80K150S50 (T2), N560P120K200S70 (T3), N760P160K250S90 (T4), N960P200K300S110 (T5), and N1100P300K500S120 i.e. farmers practice (T6) g/tree/year. In addition, 20 kg cowdung/tree was used as blanket dose. Number of fruits/tree, individual fruit weight, fruit size, stone weight, peel weight, TSS content and yield of mango varied significantly due to variations of nutrients in all the years. The highest yield and yield attributes were recorded under treatment…
