Analysis of the biological and chemical characteristics of cabbage (Brassica oleracea var. Capitata L.) Fed with compost based on sugarcane residues

Abstract

A pandemia e о conflito geopolitico entre a Russia e a Ucrania sao eventos que těm causado instabilidade económica no Peru. Motivo que foi investigado na análise das características biológicas e químicas do repolho alimentado com composto â base de residuos da cana-de-açÛcar. O objetivo foi analisar as características físicas, químicas e biológicas do repolho a partir da dose adequada de composto â base de residuos da cana-de-açÛcar e distancia entre plantas. Baseia-se na metodología aplicada com uma abordagem experimental, para a qual foi utilizado o Delineamento de Blocos Completamente Aleatorio com arranjo fatorial 4x2, que consistía em 3 blocos e 8 tratamentos que eram a combinaçao: Fl com 0, F2 com 8, T3 com 10 e F4 com 12 toneladas/ha e espaçamento (DI) com 0,30 m entre plantas e 0,60 m entre linhas e (D2) com 0,35 m entre plantas e 0,60 m entre linhas. As características físicas do repolho foram avahadas e processadas por análise de variância, as concentraçöes de nutrientes ñas folhas e a densidade estomática foram analisadas. Os resultados determinaram que T7 se destacou em altura de planta com 41,88 cm, produtividade com 26,76 tn/ha e T6 em comprimento de raíz com 20,22 cm. Na análise química das folhas TI se destacou em nitrogěnio, fósforo, potássio e T4 em calcio, magnesio e enxofre. Em densidade de estómatos T7 com 977 estômatos/mm2. Concluí que em dose adequada e maior distancia que T7 se destaca na concentraçao de nutrientes que estäo dentro dos valores normáis e alta densidade de estómatos; Portanto, essas características influenciaram ñas reaçöes bioquímicas ótimas, que obtiveram bom desenvolvimento e rendimentos que diferirám em 51,39% e 32,17% em relaçao aos controles Tl e T5.

The pandemic and the geopolitical conflict between Russia and Ukraine are events that have caused economic instability in Peru. Reason that was investigated on the analysis of the biological and chemical characteristics of cabbage fed with compost based on sugarcane residues. The objective was to analyze the physical, chemical and biological characteristics of cabbage from the adequate dose of compost based on sugarcane residues and distance between plants. It is based on the methodology applied with an experimental approach, for which the Completely Random Block Design with a 4x 2 factorial arrangement was used, which consisted of 3 blocks and 8 treatments that were the combination: Fl with 0, F2 with 8, T3 with 10 and F4 with 12 t/ha and spacing (DI) with 0.30 m between plants and 0.60 m between rows and (D2) with 0.35 m between plants and 0.60 m between rows. The physical characteristics of cabbage were evaluated and processed by analysis of variance, nutrient concentrations in leaves and stomatai density were analyzed. The results determined that T7 stood out in plant height with 41.88 cm, yield with 26.76 tn/ha and T6 in root length with 20.22 cm. In chemical analysis of leaves T1 stood out in nitrogen, phosphorus, potassium and T4 in calcium, magnesium and sulfur. InT7 stomata density with 977 stomata/mm2. It concludes that at an adequate dose and greater distance that T7 stands out in the concentration of nutrients that are within normal values and high density of stomata; Therefore, these characteristics influenced the optimal biochemical reactions, which obtained good development and yield that differed at 51.39% and 32.17% with respect to the controls T1 and T5.
