Guava under New Halfa conditions
Dawoud H. Dawoud , Fatima A/Raouf and Ahmed Ali salih
Abstract:
The present study was conducted during 1988-89, 1989-90 and 1990-91
seasons on 12 years old Guava trees grown at New Halfa sugar factory
orchard to study the effect of Nitrogen fertilizer rate on the growth,
fruit quality, and yield of Guava trees under New Halfa conditions.
N-fertilizer in from of urea was applied in to tow equal doses the first
applied in October and the second applied in June next year. The results
showed that all rates of Nitrogen led to significant increase in [tree
height and trunk circumference, fruit weight, fruit size, fruit
circumference, total soluble solids and leaf –N content] when compared
with the control through out the experimental period. The result
revealed that, the economic rate of Nitrogen fertilizer for Guava trees
under New Halfa condition, is 600 g urea to be applied in two doses per
tree per year.
