Cultivo inicial de mangabeira consorciada com adubos verdes no cerrado do sudeste de Goiás

Abstract

Mangabeira (Hancornia speciosa Gomes) occurs mainly in the Savannah and Caatinga Biomes. The fruit is the main product exploited by the fruit mainly by pulp, juice and ice cream industries. The use of legumes to contribute in the supply of nitrogen to the crops, helping in the establishment of seedlings in the field. The objective of this study was to evaluate the initial development of the H. speciosa crop, intercropped with green manures. The research was conducted in the experimental field of the State University of Goiás, Câmpus Ipameri, located at 17º 46 '30,3' 'South latitude, 48º 19' 15,6 '' West longitude and altitude of approximately 800 meters. Seedlings of H. speciosa with 11 months of age were planted in the field with spacing of 8 x 5. Among the lindas were crotalaria juncea, mucuna black, guindu beans (Cajanus cajan) and pork beans (Canavalia ensiformis), in a spacing of 0.40 x 0.80. The variables analyzed were: plant height in centimeters (cm); Stem diameter (mm); Cup diameter (cm). The data were submitted to analysis of variance and, in cases where the F test was significant, the Scott-Knott test was performed for multiple comparison of means of the main treatments. The final height increment of the mangabeira was favored by pigeon pea. The consortium with pigs' beans provided the largest final increase in stem diameter. The planting of H. speciosa seedlings in a consortium with green manure presents as promising.
