Abstract:

An experiment was conducted to study the effect of organic and inorganic fertilizers on the growth, yield, and yield components of blackgram in charland area of Chapainawabganj district. The experiment comprised of seven treatments viz. T1: Control, T2: 100% RFD (Recommended Fertilizer Dose), T3: Cow dung (5 t/ha) + 100% RFD, T4: Compost (3 t/ha) + 100% RFD, T5: Vermicompost (3 t/ha) + 100% RFD, T6: 1/3 Cow Dung + 1/3 Compost + 1/3 Vermicompost + 100% RFD, and T7: Farmer’s practice. The experiment was laid out in a randomized complete block design with three replications. Yield contributing characters of blackgram like number of clusters per plant, days to maturity, number of pods per plant, pod length, number of seeds per pod were significantly influenced by the different treatments.  Results indicated that most yield contributing characters had the maximum values in treatment T6 (1/3 Cow Dung + 1/3 Compost + 1/3 Vermicompost + 100% RFD). The highest grain yield of 13.06 q ha-1 was observed in treatment T6, and the lowest grain yield of 9.56 q ha-1 was in T1 treatment. Application of cow dung, compost, vermicompost, and fertilizer at recommended dose had a significant and positive effect on the growth and yield of blackgram. Among the treatments, the application of cow dung, compost, vermicompost with chemical fertilizers was found to be the most effective practice for blackgram cultivation in charland area of Chapainawabganj district.
