Análise de produtividade da cultura da mandioca em quatro variedades, utilizando dois tipos de culturas antecessoras, mandioca e milho

Abstract

This document presents the analysis of productivity Kg.ha-¹ per plant and income (starch content) of cassava in the period of one year. For this, we used factorial 4 x 2, with four varieties of cassava, namely, Baianinha, White, White Starch Skewer and IPR-Union, in two cultures predecessors, manioc and corn, grown on experimental area on the farm Are Matthew that is located in the municipality of North Querencia, PR. The experimental design was randomized blocks, containing eight treatments, having four repetitions in each culture predecessor, with four installments of ten plants per repetition, using conventional cassava planting on cassava, and tillage in cassava on corn, in order to compare which model of planting and which variety best'd stand out in income and productivity kg-¹ per plant. Visually the variety IPR-Union stood out more in productivity and income than others both in direct planting as in conventional, and it has been shown that the conventional planting, your time a better result with all varieties
