Husk coffee case as a conditioner of substrates in the initial growth of sweetpassion-fruit plants (passiflora alata curtis)

Abstract

The use of the coffee husks as substrate conditioners have presented potential to use in agroecological
farming systems. Therefore, the objective of this work was to evaluate the feasibility
of the use of coffee husks as conditioner of substrates for the production of sweet passion fruit
seedlings. Was used an experimental design was completely randomized in a factorial design
with 4x2 (substrates x evaluation periods) with 8 repetitions. The substrates were evaluated: T1
commercial substrate; T2 coffee husk+ tanned cattle manure + sand + (steep bank) at a ratio
of 0.5: 1: 1: 1 (v: v: v: v); T3 - + coffee straw tanned cattle manure + sand + (steep bank) in the
proportion 1: 1: 1: 1 (v: v: v: v); T4 - + coffee straw tanned cattle manure + sand + (steep bank)
in the ratio 2: 1: 1: 1 (v: v: v: v). The best results were observed in plants grown in commercial
substrate, but the T2 substrate also presents potential for use in the cultivation of passion fruit
seedlings, as it also allowed good results for the growth of plants in height, root length and root
dry weight.
