Impact of Hairy Woodrose (Merremia aegyptia L.) and Poultry Manure on Lettuce Yield

The use of plant resources available in agricultural areas is extremely important for farmers who work in this activity, contributing to an economic return in lettuce production. In view of the above, the objective was to study the Impact of hairy woodrose (Merremia aegyptia L.) and poultry manure on lettuce yield. The experiment was carried out in a completely randomized design (CRD) with six treatments and four replications. The treatments consisted of six amounts of the hairy woodrose (Merremia aegyptia L.) mixture plus poultry manure (0; 1.4; 2.8; 4.2; 5.6 and 7.0 kg m-2). For the lettuce crop, the cultivar “Babá de Verão”. Twenty-two days after transplanting, the crop was harvested and transported to the Vegetable Post-Harvest Laboratory of the Department of Agronomic and Forestry Sciences at UFERSA, where the following characteristics were analyzed: plant height; number of leaves per plant; fresh lettuce mass; lettuce dry mass. The amount of 7.0 kg m-2 of the mixture of hairy woodrose (Merremia aegyptia L.) plus poultry manure was what promoted the greatest increase in lettuce cultivation, with a maximum value of 237.97 g plant-1. The mixture of alternative fertilizer sources is extremely important in the production of leafy vegetables.
