Produção de pimentão cultivado com pó de pedra e esterco em região semiárida

Abstract

The research was carried out aiming to verify the effect of rock powder and bovine manure as natural sources for fertilization and nutrition of the pepper culture (Capsicum annuum L. cv. All Big). The experiment was carried out in the seedling nursery of the Federal Institute of Education Science and Technology of Paraíba - IFPB, Campus Sousa, São Gonçalo Unit during the period from September 2014 to August 2015. The experimental design used was in randomized blocks (DBC ) with 10 treatments and 4 repetitions, totaling 40 experimental units. The treatments were as follows: T1 = control (soil), T2 = soil + manure + rock powder (1: 1: 1); T3 = Soil + Dung + Rock Dust (2: 1: 1); T4 = Soil + Dung + Rock Dust (2: 2: 1); T5 = Soil + Dung + Rock Dust (2: 2: 2); T6 = Soil + Dung + Rock Dust (3: 1: 1); T7 = Soil + Dung + Rock Dust (3: 2: 1); T8 = Soil + Dung + Rock Dust (3: 2: 2); T9 = Soil + Dung + Rock Dust (3: 3: 2); and T10 = Soil + Dung + Rock Dust (3: 3: 3). Plant height, fresh shoot weight, fresh root weight, dry shoot weight, dry root weight, fruit length, fruit diameter, fresh fruit weight, dry fruit weight, total production and commercial production. The treatments tested significantly influenced the variables: dry and fresh root material, fresh and dry aerial part, fruit length (second harvest) and dry fruit mass (second harvest). The association of rock powder with bovine manure, natural by-products, rich in nutrients essential to the development and production of plants, presents itself as a potential alternative for use in agriculture. The T8 treatment provided greater commercial production with fruits in the commercial standard.

“…Conceição et al (2022) studying basalt powder in beans, corn and soybeans, showed positive results in crop development and productivity. Mendes et al (2020) concluded in their work that the mixture between soil, manure and rock dust promoted an increase in the quality of peppers, influencing higher total and commercial production when used in the proportions 3-3-3 and 3-2-2, respectively.…”

Use of by-Products from Bentonite Extraction in the Composition of Substrates for the Production of Okra Seedlings (Abelmoschus esculentus L.)

“…A matéria fresca da parte aérea e raiz apresentaram os maiores valores médios nos substratos S-2, S-3 e S-4, com respectivos percentuais de 4%, 8 % e 12% de subproduto da extração de bentonita, indicando que até um determinado nível de concentração do subproduto leva o crescimento e desenvolvimento das plantas, após essa concentração pode interferir negativamente no crescimento. Mendes et al (2020) estudando o uso de pó de rocha e esterço para a produção pimentão no semiárida, verificou que na proporção de 1:1:1 de esterço, solo e pó de rocha teve os melhores rendimentos, indicando que valores mais elevados podem limitar o crescimento e desenvolvimento das plantas.…”
