Effect of organic sources and efficient microorganisms on the yield of the organic banana crop (Musa spp. L.)

Abstract

The objective of this research was to evaluate the effect of organic sources (compost, earthworm humus and bocashi) and efficient microorganisms (EM) on the yield of banana cultivar Williams. The proposed treatments were: T1 compost 33.33 t.ha-1 + 5% (1 L of ME / 19 L of water); T2 worm humus 33.33 t.ha-1 + 5% (1 L of ME / 19 L of water); T3 bocachi 33.33 t.ha-1 + 5% (1 L of MS / 19 L of water); T4 compost 16.66 t.ha-1 + island guano 1.25 t.ha-1 + 5% (1 L of ME / 19 L of water); T5 (300, 50, 700 and 50 kg.ha-1 NKPSi + 5% (1 L of ME / 19 L of water), and control (15, 28 and 300), kg.ha-1 NPK with applications every 45 days ; A completely randomized block design, three blocks and repetitions was used. The number of handles and fingers per bunch, bunch weight and yield in kg.ha-1 were evaluated. The results showed that the compost dose 33.3 t .ha-1 + 5% ME, contributed in greater number of handle / bunch (9), fingers / bunch (162) and higher weight per bunch (30.63 kg.) and the highest yield 51.06 t.ha-1. of compost plus efficient microorganisms can be a relevant alternative to fertilize organic banana crops, reducing the use of fertilizers and increasing production.
