Rf. Souto et al., DOSES AND METHODS OF SIMPLE SUPERPHOSPHAT E APPLICATION ON THE MICRONUTRIENT CONTENT IN RANGPOUR LIME NURSERY, Pesquisa agropecuaria brasileira, 30(1), 1995, pp. 37-41
This study was carried out to evaluate the effects of superphosphate d
oses and application methods on rootstock Rangpour lime micronutrient
levels until graft stage. The study was carried out at the Fruit Scien
ce sector of Escola Superior de Agricultura in Lavras, MG, Brazil, fro
m August/90 to June/91. The experimental design used was in randomized
blocks in factorial scheme 4 X 8, with two replications and 24 plants
per plot. The combination of four doses (0,66, 1,33, 5,33 and 10,66 g
P2O5/plant) with eight allocation methods (in furrow; mixed in furrow
; on surface of planting line; on total area of surface plots 20% in f
urrow and 80% on total area of surface plots; 20% mixed in furrow and
80% on total area of surface plots; 20% on planting line and 80% on to
tal area of surface plots; and in four replications on plots' surface)
gave 32 treatments. The doses and allocation methods didn't affect th
e micronutrients levels of Rangpour lime. Superphosphate doses bigger
than the superior standarts doses didn't affect Rangpour lime.
