Influence of organic fertilizers on growth and yield of pawpaw

The papaya, scientifically known as Carica papaya L., is widely regarded as one of the healthiest and tastiest fruits in the world. To all intents and purposes, it is a tropical fruit, and it is grown for commercial purposes in tropical and subtropical regions (Yadava et al., 1990). It is widely held that the disease originated in Mexico and subsequently spread to virtually all of the tropical regions of the world. It is an excellent source of protein, carbohydrates, fiber, vitamins A and C, beta-carotene, and minerals such as iron, phosphorous, and potassium (Mamta et al., 2017). The papaya is most commonly found in fresh-markets, but it is also used in beverages, jams, candies, pectin, and crystallized forms of the fruit. Cooking with green fruit is similar to cooking with other vegetables. Leaves have a long history of use in traditional medicine for the treatment of a wide variety of conditions, including malaria, dengue fever, jaundice, immune modulatory and antiviral activity, and more (Singh et al., 2020). It is utilized in a number of important industrial processes, most notably in the production of the enzyme pepsin (EI Moussaoui et al., 2001), which shares many of the same characteristics as gastric pepsin. It is one of the most popular fruits in Bangladesh, despite the country’s relatively low production of papaya in comparison to that of other countries around the world (Chowdhury et al., 2008). According to Singh et al. (2012), inadequate nutrient management is one of the primary factors contributing to the low productivity of papaya. The papaya tree produces flowers and fruit continuously throughout the year; however, there is very little information available regarding the use of organic farming methods in the cultivation of this crop (Reddy et al., 2010). It is a crop that requires a lot of nutrients and responds well to fertilizer. There is a possibility that the growth yield of papaya can be affected by both organic and inorganic fertilizers.
However, the use of inorganic fertilizers without discretion alters the soil’s physical, chemical, and biological properties, and it also creates a problem for the environment and a health hazard due to the toxic residual effects of the fertilizers. Some of these factors included an increase in the incidence of pests, diseases, and weeds, all of which had an impact on productivity. On the other hand, organic fertilizers like cow dung, vermicompost, poultry manure, FYM, and mustard oil cake are helpful in improving the texture, structure, water-holding capacity, aeration, and microbial activities of soil (El-Shakweer et al., 1998).

According to the findings of a number of studies, organic farming methods not only contribute to the protection of the natural environment by reducing the amount of soil erosion that occurs, but they are also the most environmentally friendly method of crop production (Ojeniyi, 2000; Maritus and Vleic, 2001). In addition, not only are crops grown organically more nutritious, but they also eliminate the possibility of pesticide residues being passed on to consumers, which helps to ensure the safety of food. In addition, the demand for products that are produced organically is growing each and every day. In light of this, there is an urgent requirement for an increase in the production of papaya using organic methods. In light of this, the purpose of the current study was to investigate the effects of organic and inorganic fertilizers on the growth, yield, and physiochemical properties of papaya, as well as to standardize the doses for the purpose of maximizing papaya yield.
