DESENVOLVIMENTO DE MUDAS DE CAFÉ ARÁBICA EM DIFERENTES SUBSTRATOS

Abstract

This work aimed to evaluate the vegetative growth of seedlings of coffee on different substrates. The research was carried out in the city of Três Pontas, period from May to November 2020, being the experimentation carried out, in a nursery of permanent type, with the use of the shade cover with 50% brightness. Will be coffee seeds, Category S1, of the variety Mundo Novo 379/19, of the vintage 2019/2020. The treatments used were 3 different substrates, these substrates. T1 - Terra Vermelha (Terra de Barranco), T2 - Coco Powder, and T3-Humus. The substrates were arranged in polyethylene bags measuring 10 cm in width and 20 cm in length, and sowing was carried out directly in the containers, planting three seeds per bag, for subsequent thinning at 45 days, when only the most vigorous seedling remains. It was registered, in days and after DAE (days after emergence), the germination time to the 'ounce ear' stage, the plant development in (cm in height) until final evaluation, root growth and aerial part and weight of fresh and dry matter. The applied design was of blocks randomized (DBC), with 3 repetitions per block with 4 blocks each treatment, totaling 12 repetitions for each treatment. The results were subject to analysis statistics and the F test, and the treatment averages through the Tukey 1% test, with the use of the Sisvar® software (FERREIRA, 2014). Through the results presented in the experiment it was verified that the use of coconut fiber and humus as substrate for the production of coffee seedlings, resulted in positive results for the vegetative growth.
