EFFECT OF ORGANIC AND INORGANIC FERTILIZERS ON THE PERFORMANCE OF MUNGBEAN

Abstract

The experiment was conducted at the research field of the Department of Crop Physiology and Ecology, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur during the period from August 2018 to November 2018 to evaluate the effects of organic and inorganic fertilizers on the morphophysiological characters, yield contributing characteristics and yield of mungbean. The treatment consists of nine fertilizer applications (T1=65 kg TSP/ha, T2=85 kg TSP/ha, T3=45 kg TSP + 10 ton cowdung/ha, T4=45 kg TSP + 15 ton cowdung/ha, T5=65 kg TSP + 10 ton cowdung/ha, T6=65 kg TSP + 15 ton cowdung/ha, T7=85 kg TSP + 10 ton cowdung/ha, T8=85 kg TSP + 15 ton cowdung/ha.) and a control. In this experiments different combinations of organic and inorganic fertilizers were used for comparison. A promising variety, BARI mung 6 was used as a test variety. All the seeds were sown in the experimental plots on 10 September 2018 following line-sowing methods. The unit plot size was 3 m2 (2m ×1.5m). The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replicates. The results revealed that different combinations of organic and inorganic fertilizers significantly affected most of the morpho-physiological characters, yield contributing characteristics and yield of mungbean. Maximum grain yield was obtained from the application of 85 kg TSP + 15 ton cowdung/ha, while application of 85 kg TSP + 10 ton cowdung/ha ranked second for grain yield. Where the lowest value were found from control. Treatments may be ranked in the order of T8> T7> T2> T6> T5> T1> T4>T3>T0
