A soja (Glycine max) como alternativa produtiva em Alagoas

Abstract

The sugar and alcohol sector in Alagoas has undergone a severe crisis in the last 10 years with the closure of several plants, causing a strong impact on the economy of the municipalities and on the income of the producer. Many producers now have no option to sell their sugarcane production, having to look for other productive alternatives. Faced with this situation, the state government launched a set of public policies to try to seek alternatives for these producers. In this context, grains emerged as a great alternative for the region, since, we have edaphoclimatic conditions conducive to the main grain crops. With a diverse market and with high production liquidity, soy is emerging as an important alternative. Despite being the crop with the largest planted area in the country, our region lacks information to better adapt the production system to the conditions of our production environment. This study aimed to evaluate 30 varieties of soybean, in two production environments in Alagoas, one on the north coast in the municipality of Porto Calvo and another in the municipality of Campo Alegre. The experiments were implemented in randomized blocks with 30 treatments and 3 repetitions. The variables analyzed were productivity, plant height, pod insertion height and grain Weight.It was concluded that among the evaluated soybean varieties, BRS 9280 RR, BRS 8980 IPRO, ULTRA IPRO (75I77RSF), CRISTALINO IPRO (83HO113TP) are recommended for cultivation in the municipality of Porto Calvo-AL. For the municipality of Campo Alegre-AL, the varieties ULTRA IPRO (75I77RSF), FTR 4288 IPRO, BRS 7780 IPRO are recommended.
