Growing levels of goat biofertilizer in the initial growth of the pepper

Abstract

Biofertilizers have been used in agroecological production with the aim of improving conditions for plant development. The objective of the research was to evaluate the effect of the application of biofertilizer on the initial development of chili peppers (Capsicum frutescens L.). The experiment was installed and conducted under field conditions from October to December 2018, in Chapadinha, city located in Maranhão. A completely randomized design was used, with 4 treatments and 5 repetitions. The experiment corresponded to the application of biofertilizer in concentrations T1: 0%, T2: 20%, T3: 40%, T4: 60% of goat biofertilizer diluted in water. The goat biofertilizer was made using 25 kg of fresh goat manure, 200 g of ash and 500 g of brazilian candy called rapadura. Seedlings with eight definitive leaves were transplanted 0.8 x 1 m apart. The first application of the biofertilizer was performed 15 days after transplanting and the following applications of the biofertilizer were carried out at 10-day intervals until data collection. At 60 days after transplantation, data for each variable were collected. It was observed that the variables responded well to the biofertilizer, revealing significant increases in the growth and development of the pepper plant. It is recommended 4 (four) applications of doses of goat biofertilizer with a concentration between 46% (460 ml L^-1) to 48% (480 ml L^-1) to obtain pepper seedlings with good phytotechnical quality, because in this range the best results were found for most of the analyzed variables.
