Desenvolvimento inicial na cultura do porongo (Lagenaria vulgaris) sob doses de adubação orgânica

With the evolution of agricultural processes, organic fertilization has become essential in both conventional and ecological agriculture. Its use stands out for its conditioning effects on the soil, improving its attributes. The study evaluated the application of doses of organic fertilizer at the initial stage of porongo growth (Lagenaria vulgaris). A randomized block design was used, with six doses of K2O (0, 150, 300, 600, 900 and 1200 kg ha-1) with four replications. Organic fertilizer was produced with coffee grounds, banana peel, eggshell and coal. Porongo plants were evaluated after 51 days of sowing, being determined plant height (m), stem diameter (mm), number of leaves, and dry mass of the air part. The doses of organic fertilizers did not influence the evaluated characteristics, except for the number of leaves.
