Crescimento de alface (Lactuca sativa L) com diferentes doses de fosforo

Abstract

Lettuce is the most consumed leafy vegetable in Brazil, its production generates employment and added value. Good practices in the application of fertilizers are very important to guarantee a return on the farmer's investment, otherwise farmers may have low productivity caused by deficiency or excess of nutrients in the soil. Phosphorus is a very important nutrient in lettuce cultivation, several works show the importance of phosphorus in lettuce production. In this context, this work aimed to evaluate the effectiveness of using phosphorus in the development and production of curly lettuce. The work was carried out in the experimental area of the Federal University of Fronteira Sul campus Chapecó SC. The experimental design that was used is completely randomized blocks with 4 treatments and 4 replications, with 20 plants per replication, totaling 320 plants in the experiment. The treatments were as follows: 80 kg/ha, 160 kg/ha, 240 kg/ha and the Control, 0 kg/ha of P2O5.The variables analyzed were plant height, root length, diameter, wet weight, and dry weight of the plant. In relation to the variables analyzed with three doses of phosphorus, there are no significant differences.
