Morphoagronomic response in soybean varieties planted in Fluvisol soil from Cauto Cristo municipality

Abstract

This research was carried out in Carlos Bastidas Arguello Agricultural Production Cooperative from Cauto Cristo municipality, located in Granma province. Stating as the objective of this investigation: To contribute to the establishment of soybean cultivation on fluvisol soil. Also, five varieties planted in winter were evaluated. All of them were shared in a random block designed with four replications. The Phonological variables evaluated were: flowering and productive days of soybean plants, days between flowering and production, the number of leafs at the time of flowering, length and width of the leaves. Its yield and components were evaluated too, it was checked pads of each plant, grains for each fad and it was weighted 100 grains. The data were processed by variance analysis of double classification and the multiple comparisons of means were performed by Duncan test top ≤ 0,05. The results showed that the earlier and later variety were William-82 and Canada with 28 and 33 days, the longest period to fructify it was Canada, with 38 days, the days between flowering and production ranged from 4,3 (Cubasoy 23) to 5.8 (William 82). The highest number of leafs at the time of flowering was showed by William, the maximum length and width of the leaves was presented by Doucrop, the highest yield corresponded to Cubasoy 23 with 1,29 t. ha-1 in correspondence to the highest number of pods and weighing of 100 grains. The economic assessment showed that all varieties showed profitability, resulting Cubasoy 23 the best performing with a cost-benefit of $ 0,58.
