The experiment was conducted at the farmer’s fields of three Charlands in Bangladesh during November 2019 to July 2020 for establishing new technologies for enhancement of productivity through innovative soil management practices. The experiments were established in a randomized complete block design using six treatments and three replications. Treatments of the experiments were T1 = FP (Farmers’ Practice) (Control), T2 = RF (Recommended Fertilizer) + Vermicompost (3t/ha), T3 = RF (Recommended Fertilizer) + Quick Compost (3t/ha), T4 = RF (Recommended Fertilizer) + Standard Organic Fertilizers (3t/ha), T5 = RF (Recommended Fertilizer) + Poultry Manure (3t/ha) and T6 = RF (Recommended Fertilizer) + Biochar (3t/ha). The soil status in all selected Charlands were very low to optimum. Results of the experiment showed that application of organic fertilizers along with inorganic fertilizers produced significant (p<0.05) variation in growth and yield parameters of the crops. The findings from the study showed that different organic fertilizers showed better performance compared to Farmer’s practice. The statistically maximum fruit yield (41.35t/ha) of pumpkin, grain yield (3.24t/ha) of millet and tuber yield (43.69t/ha) of sweet potato was recorded in biochar treated T6 treatment compared to other treatments. Besides, the statistically highest fresh fruit yield (29.50t/ha) of snake gourd, fresh fruit yield (20.80t/ha) of okra and yield (74.16t/ha) of Indian spinach were recorded in poultry manure treated T5 treatment compared to other treatments. Comparatively higher growth and yield of different crops were obtained from poultry manure along with inorganic fertilizers which was followed by biochar and quick compost application. It is recommended to the farmers to use organic fertilizers along with inorganic fertilizers.
