SOURCES ALTERNATIVE OF ORGANIC MATTERS FOR MIX OF SUBSTRATES FOR THE PRODUCTION OF YELLOW-PASSION SEEDLINGS

Abstract

Most of the time, seedlings of yellow passion fruit are produced from seeds. The success in the establishment of the culture depends on several factors, such as the use of seeds of good quality and choice of the best substrate. This work the aim, was to evaluate sources alternative of organic matter in the mixture of substrates for the production of yellow-passion (Passiflora edulis Sims f. flavicarpa Deg) seedlings. The experimental design was in blocks completely randomized, with ten treatments, with four repetitions and ten plants per parcel, been the treatments: pure soil (S), soil + goat manure (S + GM) in the proportion of 3:1, soil + sheep manure (S + SM) in the proportion of 3:1, soil + bovine manure (S + BM) in the proportion of 3:1, soil + earthworm humus (S + H) in the proportion of 3:1, soil + goat manure + sheep manure (S + GM + SM) in the proportion of 2:1:1, soil + goat manure + bovine manure (S + GM + BM) in the proportion of 2:1:1, soil + sheep manure + bovine manure (S + SM + BM) in the proportion of 2:1:1 , soil + sheep manure + bovine manure (S + SM + BM) in the proportion of 2:1:1, pure soil fertilized with single superphosphate and potassium chloride (S + P + K) at doses of 1 kg m-3 and 0.5 kg m-3 respectively and pure soil fertilized with only single superphosphate (S + P) at a dose of 1 kg m-3. The use of goat and sheep manure in mixtures of substrates provided good results in the production of Yellow-passion seedlings. Of all the tested substrates, the substrate soil + bovine manure in the proportion of 3:1 promoted the best development of the yellow-passion seedlings.
