Résumé:
This study aimed to investigate the effects of concentrations of bio-fertilizers and
irrigation laminas on the growth, yield and quality of production of chillies and peppers.
The experiments with these cultures were conducted at the Center for Agricultural
Sciences and Humanities - CCHA , at the State University of Paraíba - UEPB , Campus IV
, in Catolé do Rocha, Paraíba. In two experiments , conducted at different times , the
effects of five concentrations of biofertilizers ( C1 = 0 , C2 = 15 , C3 = 30 , C4 = C5 = 45
and 60 ml L-1 ) and five irrigation laminas ( L1 = 80 % = 90 % L2 , L3 = 100 % , L4 and L5
= 110 % = 120 % IN - Irrigation Water Need ) on the growth , yield and quality of
production of chillies and peppers. The experimental type was a randomized block design,
with 25 treatments, in a 5x5 factorial arrangement with 4 replications , totaling 100 plots .
The experimental plots in both experiments consisted of two plants. The biofertilizers used
in the fertilization coverage were produced in an anaerobic form , in plastic containers (
digesters ) with an individual capacity for 240 liters. The research results show that the
growth variables of chilli were increased to great limits of concentrations of biofertilizers ,
with reductions from these levels ; the growth variables of chili had linear increases with
increasing concentrations of bio-fertilizers and irrigation laminas; the fresh and dry matter
of chilli increased linearly with increasing concentration of biofertilizers, being more
pronounced in bigger irrigation laminas; the maximum number of fruits per branch and per
plant of chilli was provided by the concentration of biofertilizers of 60 ml L-1 within the L5
lamina ( 120 % IN ) or the optimum lamiina of 100 % IN within the concentration of 60 ml
L-1; the maximum weights of fruit per branch and per plant of chilli were provided by the
concentration of biofertilizers of 60 ml L-1 within the L5 lamina ( 120 % IN ) or by the IN
blade of 120 % within the concentration of 60 ml L-1 ; the maximum number of fruit per
plant was provided by the optimum concentration of 35.6 ml L-1 within the L4 lamina (
110 % IN ) or by the optimal lamina of 104.5 % within the IN concentration of 30 ml L-1 ;
the fruit weight of chilli increased linearly with increasing irrigation lamina ; the total
soluble solids of chillies were reduced with increasing concentration of biofertilizers to the
extent of 30.9 ml L-1 , with increased growth thereafter; and the total soluble solids of
pepper increased linearly with increasing concentration of biofertilizers.
