The Influence of the Nutritional Condition of Papaya on the Development and Productivity of Plants

Adilov Hikmatilla Abdukhalilovich

Abstract: The complex of external conditions (aeration, nutrition and moisture provision) have a huge impact on the size of the root system, the nature of its placement along the soil horizons and an active aboveground part formation, capable of maximally nutrients usage. The interaction of the root system with the environment, its absorption of nutrients from the soil is an active physiological process connected with the vital activity of the whole organism. A big role in this process belongs to agro technical methods and, above all, the introduction of fertilizers that contribute to the creation of a powerful absorbing surface of the roots, which is extremely important for the mineral nutrition of plants. The results of the research on the main types of macro-fertilizers usage (NPK-Nitrogen-Phosphorus-Potassium) when growing papaya (melon tree) on intensive technology in greenhouse conditions were given in this article. It was established by the research, that the best conditions for the development of the root and above-ground system of plants are created when N140 P70 K35 kg/ha is applied to the soil annually. Under these conditions, two years old plants form up to 22-23 fruits with a total yield of 117.52-122.65 t / ha.
