Effect of biological and organic fertilizers on growth processes, productivity and quality of melon fruits under Southeastern Kazakhstan

Abstract

In Kazakhstan, melon growing is cultivated using chemical fertilizers. Organic production is not practiced where there being no research. Our country, possessing a great high-quality variety, can be the focus of world community attention as a producer and supplier of ecological melon. Besides economic interests, changeover from traditional methods of cultivation to biological one is of great importance in ecological aspect. Unregulated and too high agrochemicals application causes a number of negative consequences, upwards from soil pollution with severe salts to poisoning caused using low-quality products. The most popular and regulated elements of biological melon cultivation in production include organic fertilizers instead of chemical ones. Therefore, our research is aimed to study bioorganic fertilizers on melon culture under Southeastern Kazakhstan. Scientific experiments were held at the experimental sites of the «Fruit and Vegetable Research Institute» LLP. We experimented using classical research methods generally adopted in melon cultivation. The findings showed that bioorganic fertilizers improve the growth parameters and quality of melon culture, and increase fruit productivity. The yield growth on the studied options for control ranged from 31.23% to 41.71%, depending on the nutritional conditions.
