Tare cv Blanca was evaluated under two plant spacings and three fertilizer
levels in a Corozal clay soil. Plant distances evaluated were 0.91 m x 0.30
m and 0.91 m x 0.6 m. Fertilizer levels evaluated were 0, 56 and 112 grams
per plant of a 14-3-13 commercial mixture. The evaluation was performed wi
th two different planting methods: bench and flat. Results showed that an i
ncrease in the planting distance caused a significant reduction in the corm
fresh yield but a significant increase in the average corm weight in all o
f the planting methods. The fertilizer levels had no effect on the corm fre
sh yield nor on the average corm weight. Fertilizer levels had no significa
nt effect on the foliar concentration of N, P, K, Ca and Mg measured six mo
nths after planting. Average foliar concentrations of these elements across
treatments were 4.6, 0.36, 4.1, 0.23 and 1.5%, respectively.
