Desenvolvimento inicial da pimenta biquinho sob irrigação e adubação nitrogenada

Abstract

The greatest limitation to the cultivation of small green pepper is the inadequate moisture of the soil and also the lack of nutrients in the soil. The objective of this research was to evaluate the agronomic indicator sofred pepper under water slides and nitrogen doses. The experimente was carried out in the experimental área of UFMT, Campus of Rondonópolis-MT. The soil was classified as Latossolo vermelho and the climate is Aw, being warm and humid, with rainy summer and dry winter. The experimental design was a randomized complete block design with five levels of water (40,60,80,100 and 120% of the reference evapotranspiration (ETo) and also divided into nitrogen dosages (0.60,120,180,240 kg ha-1), with four The following variables were evaluated: number of leaves, plant height, chlorophyll index, and stem diameter, and the results of the regression test The plant height, stem diameter and number of leaves variables showed a significant difference between the treatments only for the nitrogen doses, adjusted to the quadratic regression model, and for the SPAD Reading there was no significant difference between the treatments. Nitrogen doses influenced the initial development of the poutine pepper.
