Agronomic evaluation of four improved rice varieties in different sowing periods
ResumenA study to evaluate the agronomic performance of four rice varieties in different seasons, on flooded soil, using direct plantation, was developed at the Local Station for Grain Research, in the municipality of Vertientes, province of Camaguey, Cuba. A block random design was used in the study, with five replicas, through a bifactorial experiment with four treatments (Prosequisa 4, IA Cuba 31, IACuba 40, and Jucarito 104, as control), the sowing period included January, February, March, April, May, June, July, and August. The parameters evaluated were, cycle (days) from germination to harvest, final plant height, fertile panicles per m2, filled grain per panicle, 1000-grain mass (14% humidity), crop yields and industrial quality. The highest yields were accomplished in February and June (pattern variety and Prosequisa 4, with 8.2 t/ha-1, in each month). Concerning industrial yields, the best results were achieved in IACuba 31 (66.4; 66.1; and 63.3% full white grain) in February, June and July. The most profitable varieties were Prosequisa 4, Jucarito 104, and IACuba 31, in the different seasons evaluated.
