Effects of Organic and Inorganic Fertilizers on Growth and Yield of Different Crops at Charlands in Bangladesh

Abstract

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.

Effect of Organic Manures and Mineral Fertilizers on Soil Properties and Yield of Sweet Pepper (Capsicum annuum L.)

“…This implies that utilization of organic or mineral fertilizers alone is never a suitable solution for maintaining soil health and increasing crop productivity. Therefore, the integration of inorganic and organic sources of plant nutrients is supposed to the best approach for the maintenance of soil fertility and better crop production on a sustainable basis [14][15][16][17][18][19]. It has been revealed in literatures that combine application of organic and inorganic fertilizers has significant positive effect on different vegetable crops [20][21].…”

Influence of an Organic Fertilizer on Agronomic Characteristics and Herbaceous Plant Diversity in a Greek Ecosystem: The Case of Cretan Dittany (Origanum dictamnus L.)

“…The organic fertilizer has the advantage of releasing the nutrients gradually. This slower release process of nutrients facilitates the plants to assimilate more effectively the nutrients in a natural way, promoting a balanced and sustainable growth of plants without the negative effects associated with excessive nutrient uptake [48,49].…”

Environment-friendly nitrogen management practices in wetland paddy cultivation

“…In INM, nutrients are supplied from all possible sources of inorganic fertilizers, organic manures, and biofertilizers for crop production (Dwivedi et al, 2016). INM maintains soil fertility, enhances crop yield and quality, reduces nutrient losses from the soil, improves NUE, curtails production cost, and minimizes energy consumption in agriculture (Dwivedi et al, 2016;Panda et al, 2019;Afrad et al, 2021Afrad et al, , 2022a. The partial factor productivity of applied N (PFPN) in rice ranged from 26 to 52 kg grain kg −1 N for recommended dose (RD) of NPK, whereas the value increased to 33-77 kg grain kg −1 N for 75% of RD + 25% N from FYM (Dwivedi et al, 2016).…”
