TY - JOUR T1 - Improved Soil Fertility Level Increases the Growth and Yield of Soybean by Enhancing Chlorophyll Content A1 - Soyema Khatun A1 - Mahi Imam Mollah JF - Entomology and Applied Science Letters JO - Entomol Appl Sci Lett SN - 2349-2864 Y1 - 2023 VL - 10 IS - 2 DO - 10.51847/QKzokd8BT3 SP - 43 EP - 49 N2 - The study was conducted at the BINA substation, Barisal to evaluate the effect of soil fertility status on chlorophyll content, growth, and yield of soybean. Binasoybean-3 was used for this study. The study was laid out in a randomized complete block design (RCBD) with three replications. Four soil fertility conditions such as F0 = no fertilizer, F1 = Rhizobium inoculation, F2 = NPK fertilizer, and F3 = Organic matter (Cow dung 2 tons ha-1). Macronutrient nitrogen (N), phosphorus (P), and potassium (K) were supplied as urea, triple super phosphate, and muriate of potash. The lowest chlorophyll content was measured in control plants while the highest from NPK-treated plants which was 21.78% more compared to control. This increased chlorophyll content in NPK-treated plants results in the highest total dry mass (TDM) accumulation at both 80 and 90 days after sowing (DAS) compared to other treatments. The absolute growth rate was maximum in NPK-treated plants measured at both 80 DAS and 90 DAS providing a 60.83 and 81.49% increase compared to control, respectively. Yield contributing traits such as no. of branches per plant, no. of pods per plant, no. of grain per pod, and 1000 grain weight found maximum in NPK treated plants. Finally, grain yield was maximum in NPK-treated plants which was a 97.46% increase compared to control. Results revealed that sufficient application of NPK is required for maximum grain yield in soybean. Sufficient NPK increased the chlorophyll in plants which eventually increased the plant growth and yield as well.
