EFFECT OF BARI IMO SOLUTION WITH INORGANIC FERTILIZERS ON GROWTH, YIELD AND QUALITY OF CARROT

Abstract

The experiment was conducted at the Olericulture Research Field-2, Horticulture Research Centre, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during the November, 2019 to February, 2020 to evaluate the effect of BARI IMO solution with inorganic fertilizers on growth, yield and quality of carrot. The experiment consisted of two following factors as Factor A: Four levels of IMO (Indigenous micro-organisms) solution, viz., S 0 = Control (No IMO solution), S = 150 ml/L IMO solution, S 2 = 250 ml/L IMO solution, S = 350 ml/L IMO solution and Factor B: Four levels of inorganic fertilizer, viz., F 1 3 = 25% RDF (Recommended Dose of Fertilizer), F 2 = 50% RDF, F 3 = 75% RDF, F = 100% RDF. The experiment was laid out in RCBD design with three replications. Various data and parameters were recorded during the experiment. In case of IMO solution, the highest yield (24.52 t/ha) was found in S 3 4 and the lowest was observed in S . In combined application of IMO solution and inorganic fertilizers, the highest root length (18.67 cm), root diameter (4.87 cm), root pith flesh ratio (2.14), root dry matter content (17.78%), marketable yield (25.24 t/ha), TSS (9.07%), β carotene content (36.85%), total sugar content (11.09%) and reducing sugar content (3.03%) were found from the treatment combination of S 3 F 3 whereas, S 0 F 1 0 showed the lowest results. Likewise, the maximum yield (26.49 t/ha) was also recorded from S 3 F whereas, the minimum yield (15.20 t/ha) was found in S 0 F 1 3 . The highest BCR (2.58) was obtained from the treatment combination in S 3 F 3 whereas, the lowest result was observed from S . Therefore, S 3 F is considered to be the most effective treatment combination (350 ml/L and 75% RDF) for increasing growth, yield and quality of carrot.
