Use of fertigation for obtaining high yields and quality in the papaya crop.

Fertigation consists in applying irrigation and fertilizers at the same moment. With this technology it is possible to provide all nutrients to the plant roots, which implies an energy saving by the plant in the nutrients absorption resulting in greater fruit yield.

To be able to inject fertilizers into the irrigation system, it is necessary to have a Basic injection system, which allows to dose according to the phenological crop’s stage the required fertilizer quantities for that phase. With this system, a fertilizer saving is achieved, better assimilation and distribution of nutrients, fertilizer supply according the phenological stage needs, fertilizers distribution economy since the unnecessary hand labor is avoided (backpack sprayer application).

Importance of nutrition in the papaya crop.

The papaya crop presents a rapid and constant development together with an early, continuing and simultaneous flowering and fruit development. Therefore, it requires a high water and nutrients supply during the entire cycle. Among the factors that can modify the production of the crop is the use of associated fertilizers to irrigation as principal mean for increasing the crop productivity.

Papaya responds very well to fertigation. Fertilizer application must be done in a balanced, fragmented and completed way, also according to the phenological crop’s stages. Obviously taking in consideration the water, soil and foliar analyses to adjust and optimized the crop’s nutritional program.

Nutrient

Function

Deficiency

Nitrogen (N)

The main Nitrogen function is to generate leaves, stems and fruits growth. Its inadequate management can favors an excessive plant growth as well as bad quality fruits.

Deficiencia 1

Phosphorous (P)

The main Phosphorus functions are to promote roots growth as well as to fruit set and maturity.

Deficiencia 2

Potash (K)

Potash is highly demanded by the crop, being an essential nutrient for obtaining great size fruits, with high sugar levels and total soluble solids. The N/K rate is of great importance for the crop, since a misbalance among these two nutrients affects the fruit quality. A rate near 1 allows obtaining fruits with thick skin, intense color and optimum flavor characteristics.

Deficiencia 3

Calcium (Ca)

Calcium is an associated nutrient to the growth and roots development, also as constituent of the cell wall of leaves, stems and fruits. The continuing supply of this nutrient allows obtaining more disease resistant fruits and longer post-harvest life.

Deficiencia 4

Magnesium (Mg)

The main function of Magnesium is as chlorophyll molecule component, therefore it participate in the plant photosynthesis processes. Besides, it favors the photosynthates transport from the leaves to the fruits, improving their size, flavor and color characteristics.

Deficiencia 5

Boron (B)

Boron is the most important micronutrient for the papaya crop. Its main functions are to favor the normal fruits formation, directly participating in the pollinic tube growth, as well as to favor the photosynthates transport from the leaves to the fruits.
