Effect of the application of micronutrients and nitrate-ammonium in the contents of chlorophyll and in the depuration of exogenous, in the cultivation of fruta bomba (carica papaya, l.)

Abstract

The chlorosis terrn indicates the absence of chlorophyll and other pigments, so much in leaves as in fruits of plants with deficiencies of faith. The affected cultivations for chlorosis present reduction of the vigor, quantity and quality of the production by suffering alterations the normal process of ripeness. The prevention of the chlorosis is acquiring great relevance since, as consequence of the intensification of the cultivation, the need of nutrients is major and the symptoms ofthe deficiency offaith are observed more and more. In the investigation decided the causes they cause the appearance of ferric chlorosis in Fruta Bomba (Carica Papaya, L.) in the affected areas, byestablishing different treatments for your correction, by evaluating the results ofthe effect of applications combined of micronutrients and nitrate-ammonium in the contents of chlorophyll and in the depuration of H202 exogenous as altemative to correct the effects ofthis type of chlorosis. As a main result have the determination of the influence of formulations of micronutrients in the contents of chlorophyll (SPAD). lt corroborated to him the influence ofthese micronutrients in the depuration of peroxide ofhydrogen (H202) exogenous, existed a positive correlation between the content of chlorophyll and the depuration of peroxide of exogenous hydrogen, which coincides with results obtained for diverse authors, for a major resistance to 70%, the plants needed 55 SPAD or more. The results of the work are feasible to apply in the appointed to areas to the cultivation ofthe Fruta Bomba in the province of Pinar del Río.
