Behavior of growth and agricultural yield of two sorghum varieties (Sorghum bicolor L. Moench) in the dry season in Los Palacios town
Main Article Content
Abstract
and Technological Unit of “Los Palacios” with the objective
of evaluating the behavior of growth and yield of two
sorghum varieties (Sorghum bicolor L. Moench) in Los
Palacios town. The varieties Gilded ISIAP and CIAP 132
R were used, which were sowed in the sowing dates of
December, 2009 and February, 2010. The technology of
direct sowing was used and the cultural activities were
developed according to that recommended by the Crop
Technical Instructive. A Randomized complete experimental
design with four replicas was used. The dry mass distribution
of the air part and the leaf area index, in 10 plants for each
parcel, every 15 days until the physiologic maturity, were
evaluated. With these variables the dynamics of growth
were established and the agricultural yield was determined,
data that were processed by T Student, to 5 % of error
probability. Considering the results it can be concluded
that yields were influenced by sowing date and its biggest
values were in correspondence with a bigger development
of the leaf surface. Both varieties can be used in the town
since their productive results exceed the values set in Cuba
for sorghum crop.
