INFLUENCE OF ORGANIC, INORGANIC AND BIO-FERTILIZERS ON MORPHOLOGICAL CHARACTERS AND YIELD OF MUSTARD

Abstract

Bio-fertilizer and organic products plays a significant role in crop cultivation with reduced chemical fertilizer use which are eco-friendly natural sources. Use of inorganic fertilizer in combination with bio-fertilizer and organic manure maximize mustard yield and also can be considered as an alternative to sustainable agriculture development. The present study aims to influence of organic, inorganic and biofertilizers

on morphological characters and yield of mustard (BARI Sarisha-14), conducted at the farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period of November 2019 to February 2020. Fourteen treatments viz. (i) Control (no fertilizer), (ii) Cowdung 100%, (iii) Inorganic fertilizer 100%, (iv) Decoprima 100%, (v) Cowdung 100% + Inorganic fertilizer 100%, (vi) Cowdung 100% + Inorganic fertilizer 75%, (vii) Cowdung 100% + Inorganic fertilizer 50%, (viii) Cowdung 100% + Decoprima100%, (ix) Inorganic fertilizer 100% + Decoprima 100%, (x) Inorganic fertilizer 75% + Decoprima 100%, (xi) Inorganic fertilizer 50% + Decoprima 100%, (xii) Cowdung 100% + Inorganic fertilizer 100% + Decoprima 100%, (xiii) Cowdung 100% + Inorganic fertilizer 75% + decoprima 100% and (xiv) Cowdung 100% + Inorganic fertilizer 50% + Decoprima 100% were considered for the present study. The experiment was laid out in randomized complete block design (RCBD) with three replications. The results of this study showed that the sole application of either organic or inorganic fertilizers and combined application of organic and inorganic fertilizers influence the growth and yield of mustard. Among the performance of all treatments, cowdung 100% + inorganic fertilizer 100% + decoprima 100% gave the highest plant height (97.81 cm), number of leaves plant -1 (45.80) number of branches plant -1 (9.33), length of inflorescence (40.22 cm), number of silliquae inflorescence -1 (40.73), number of filled silliquae plant -1 (98.73), number of seeds silliquae -1 (37.93), seed weight of 100 siliquae (13.50 g), seed weight plant -1 (9.60 g) and seed yield (1803.00 kg ha ) whereas control treatment (no fertilizer) showed least result on the respected parameters. But no significant difference was found between T (Cowdung 100% + Inorganic fertilizer 100% + Decoprima 100%) and T 12 11 (Cowdung 100% + Inorganic fertilizer 75% + Decoprima 100%) treatments though both the sole and/or combined application of organic fertilizer (cowdung) and bio-fertilizer (decoprima) contribute to reduce the amount of inorganic fertilizer. Combined application of organic fertilizer (cowdung) and bio-fertilizer (decoprima) contributed to reduce the amount of inorganic fertilizers for mustard cultivation under the climatic and edaphic condition of Sher-e-Bangla Agricultural University. -1
