Comparação entre a semeadura direta em covas e em sacolas plásticas sobre as características morfométricas do maracujazeiro-amarelo.

Abstract

The yellow passion fruit (Passiflora edulis Sims, F. flavicarpa Degener) is of great commercial importance for Brazil, especially for the Northeast, due to the physical-chemical quality of the fruits. The cultivation is usually done with seedlings, which increases the cost and the time of production. The objective of this work was to evaluate the germination and growth of yellow passion fruit sown directly in pits and bags under field conditions. The experiment was conducted from March to October 2016 at the Poços D'Água site, located in the municipality of Cuité-PB, in a randomized block design, with 5 treatments, 5 replicates / treatment. Seeds of yellow passion fruit selected by the quality of the plants and fruits were sown in plastic bags (T1), aiming the production of seedlings, and directly in pits (T2 to T5). The germination speed index, germination percentage and initial plant growth were statistically analyzed. The germination speed index was higher when the yellow passion fruit seed was planted directly in the growing pit than in sacks. The percentage of germination was not influenced by the way of planting of yellow passion fruit. The plants grown from direct sowing in pits had a significantly higher height, number of leaves and stem diameter than those grown in sacks. Plant growth was not hampered by high water salinity and soil quality. The methodology of direct sowing in pits proposed in this work presents great potential for application in the cultivation of yellow passion fruit in the region of Curimataú Paraibano.
