Combined effect of burned rice husks with controlled release fertilizer on the development of seedlings of Coffea arabica L. Variety "Isla 6_14".

Abstract

The Jibacoa region is a rice producing region generating high amounts of husk, used as an alternative for fertilizer. The convenience of tube technology for seedling production using rice husk combined with soil, as a substrate, is an option to produce coffee seedlings in the region. The experiment was carried out in the nursery of the Jibacoa Agroforestry Experimental Station, Villa Clara province, Cuba, located at 22°.01'N and 79°.58'W, in the period between November 2019 and June 2020. The effect of different proportions of burned rice husks (BRH)., soil and different Multicote® doses on the development of coffee seedlings established in tubes as containers was evaluated. A factorial completely randomized experimental design was used with 26 treatments. Seven months after the establishment, the variables height, stem diameter, number of paired leaves, leaf area and total dry mass were evaluated in 20 plants per treatment: The treatment consisting of 25% BRH + 75% soil + 3 g of Multicote® reported the highest mean values of height, stem diameter and number of leaves of seedlings of Coffea arabica L Var."Island 6_14.
