Evaluation of Integrated Nutrient Management for Mandarin Orange Production in Hot Humid Region of Bangladesh

The study was aimed at boosting up the yield and profitability of mandarin orange cultivation through integrated nutrient management. The experiment consists of six treatments laid out in a randomized complete block design. Data were recorded on growth, yield, quality and profitability. All the parameters were influenced by different integrated nutrient approaches. Growth, yield and qualitative parameters were found to be influenced by different nutrient management options. Plants received 60% of their required nutrients as per soil test basis from chemical fertilizer and 40% from Cow dung (T4) were found best with yield and qualitative parameters along with highest marginal rate of return. Hence, this may be a wise and economic choice for farmers, producing mandarin orange var. BARI Manderin-1 in hot humid tropical region of Bangladesh.
