    EFFECT OF ORGANIC AND INORGANIC FERTILIZER APPLICATION ON RICE PRODUCTION (BRRI dhan29)
    (DEPARTMENT OF SOIL SCIENCE, 2021) HASAN, JAHID
    The experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from December 2020 to May 2021 to examine the effect of organic and inorganic fertilizer application on rice production (BRRI dhan29). The experiment consisted of eight treatments viz. T ii 0 (control; no nutrient application), T (100% RDCF: N 120 P 20 K 40 S 20 Zn 2.5 kg ha -1 ), T 2 (100% cowdung - 10 t ha (100% poultry manure - 5 t ha -1 ), T 4 (50% RDCF + 50% cowdung), T (50% RDCF + 50% poultry manure), T 6 (25% RDCF + 75% cowdung) and T 7 5 (25% RDCF + 75% poultry manure). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Results showed that a significant variation among the treatments was found while different nutrient levels (organic and inorganic) applied in different combinations. The treatment T 1 (100% RDCF: N 120 P 20 K 40 S ) exhibited the highest plant height at 60, 90 DAT and at harvest (83.73, 95.87 and 94.37 cm, respectively) while the treatment T (50% RDCF + 50% cowdung) showed the highest number of tillers hill -1 4 (13.13, 15.33 and 17.73, respectively) whereas control treatment T (no nutrient application) showed the minimum results. Again, the treatment T 4 0 (50% RDCF + 50% cowdung) showed the highest number of effective tillers hill -1 (16.33), flag leaf length (24.28 cm), number of filled grains panicle (165.40), panicle length (25.94 cm), 1000 seed weight (21.90 g), grain yield (7.66 t ha -1 ), straw yield (8.96 t ha -1 ) and harvest index (46.09%) followed by T (50% RDCF + 50% poultry manure) and T (25% RDCF + 75% poultry manure) whereas the control treatment T 0 7 (no nutrient application) performed the lowest results on the respected parameters. In case of post harvest soil, different treatments of organic and inorganic fertilizers combinations showed non-significant variation on particle density, pH and organic carbon content but available P and S of post harvest soil affected significantly. The treatment T (50% RDCF + 50% cowdung) showed highest P (23.42 ppm) and S (27.40 ppm) content of post harvest soil whereas the lowest P and S content was obtained from control treatment T 4 (no nutrient application). So, the treatment T 4 0 (50% RDCF + 50% cowdung) can be considered as very promising treatment for rice production (BRRI dhan29) to obtain higher grain yield.

    INFLUENCE OF ORGANIC, INORGANIC AND BIO-FERTILIZERS ON MORPHOLOGICAL CHARACTERS AND YIELD OF MUSTARD
    (DEPARTMENT OF AGRICULTURAL BOTANY, SHER-E-BANGLA AGRICULTURAL UNIVERSITY, DHAKA, BANGLADESH, 2021-06) HASAN, JAHID
    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
