PINEAPPLE YIELD, FRU1T CHARACTERISTICS AS AFFECTED BY SOIL MANAGEMENT SYSTEMS AND PLANTING TECHNIQUES
Abstract
The choice of an adequate soil management system and planting techniques increases pineapple yield and lowers the production costs as well. To estimate the effect of different soil management systems (conventional tillage, strip-tillage and no-tillage), and two planting techniques (furrow and spear) on productivity, fruit characteristics, percentage of sprouting, and seedling production, a field experiment was carried out from August/1997 to January/1999 at the Estação de Pesquisa e Produção of FEPAGRO, Maquiné, Rio Grande do Sul, Brazil. The soil type was a clay loam Argiudoll. Results showed that productivity and harvest percentage were higher in conventional tillage (1 1.94 ilha and 52%) than in no-tillage (5.67 t/ha and 27.7%). The productivity and harvest percentage in furrow and spear plantings did not differ statistically. Fruit diameter and length, crown size, brix degree, number and average weight of sprouts were not affected by the different treatmcnts.
