Effects of organic fertilizer on growth and yield of tomato

Abstract

The experiment was conducted during rabi season 2019-2020 at Agricultural Research Station, On Farm Research Division, Alamnagar, Rangpur to find out the useful effects of organic fertilizer on growth and yield of tomato. The experiment was arranged in a randomized complete block design (RCBD) with five treatments in three (03) compacted replicate blocks. The treatments included T₁: 100% Recommended Chemical Fertilizer (RCF), T₂: 85% CF + 3 tha^-1 organic Fertilizer (OF), T₃: 85% CF + 1 tha^-1 OF, T₄: 70% CF + 3 tha^-1 OF and T₅: 70% CF + 1 tha^-1 OF. The highest yield was observed in T₂ (50.59 t ha^-1) due to more number of fruit plant^-1& weight of fruit plant^-1 and the lowest was in T₅ (35.32 t ha^-1). These results may be due the parameters of growth components increased with increasing amount of organic and inorganic fertilizers applied. Combination of organic and inorganic fertilizer treated plots produced higher yield than plots without combination of organic and inorganic fertilizer. The highest gross return (BDT. 607080) was found in T₂ treatment and the lowest gross return (BDT. 423840) was recorded from T₅. The highest gross margin (BDT. 328520 ha^-1) was obtained from T₂. The lowest gross margin (Tk. 145280 ha^-1) was obtained from T₅. Integrated nutrient management (combination of organic and inorganic fertilizer) is the best option for higher tomato production in Bangladesh.
