RESUMOO presente trabalho foi realizado com o objetivo de avaliar o desempenho do sorgo forrageiro em diferentes tipos de cobertura morta na sua fase inicial de desenvolvimento. O experimento foi realizado em uma área pertencente ao Instituto Federal de Educação, Ciência e Tecnologia do Ceará/Campus Sobral, conduzido com delineamento em blocos casualizados com quatro repetições. Os tratamentos (coberturas) aplicados foram: Solo sem cobertura (Testemunha); Bagana de carnaúba; Esterco caprino; e Serragem. As coberturas foram depositadas logo após o plantio da cultura. Aos vinte dias após o plantio avaliou-se a altura da planta (cm), o comprimento da raiz (cm), o diâmetro do colmo (mm), o número de folhas, o peso fresco da parte aérea (g), o peso fresco da raiz (g), o peso seco da parte aérea (g) e o peso seco da raiz (g). Os resultados mostraram que plantas de sorgo que receberam esterco caprino como cobertura morta apresentaram maior altura, maior diâmetro do colmo, maior número de folhas e maior peso da parte aérea. Assim, pode-se concluir que o uso de esterco caprino utilizado como cobertura morta favorece o desenvolvimento da parte aérea de plantas de sorgo forrageiro. PALAVRAS-CHAVE: altura da planta, comprimento da raiz, Sorghum bicolor. SOIL COVERAGE WITH ORGANIC MATERIAL FOR INITIAL DEVELOPMENT OF SORGHUMABSTRACT The present study was carried out with the objective of evaluating the performance of sorghum in different types of mulch in its initial development phase. The experiment was carried out in an area belonging to the Instituto Federal de Educação, Ciência e Tecnologia do Ceará/Campus Sobral, conducted with a randomized complete block design with four replicates. The treatments (coverage) applied were: Soil without cover (Control); Carnauba leaf; Goat manure; and Sawdust. The coverages were placed shortly after planting the crop. Twenty days after planting, the plant height
The objective of this work was evaluating the nitrogen fertilization splitting on the performance of green corn, grown in rainfed system. The experiment was carried out in Forquilha, Ceará state. Two varieties of corn (Sweet and Gorutuba)were used in the experiment, grown in five types of nitrogen fertilization in the crop cycle (one; three; six; nine; and twelve applications). The variables evaluated were: plant height, stem diameter, number of leaves of the plant, plant fresh mass, plant dry mass, ear mass plant -1 , marketable ear mass plant -1 , marketable husked ear mass plant -1 , marketable unhusked ear mass plant -1 , number of ear plant -1 , number of marketable ear plant -1 , length of husked marketable ear, length of marketable unhusked ear, diameter of marketable husked ear, diameter of marketable unhooked ear, number of rows marketable ear -1 and number of grains row -1 of marketable ear. The data were subjected to analysis of variance by the F test (P < 0.05) and the treatment means were compared by the test of Tukey (P < 0.05) and subjected to regression analysis. It was observed that the split of nitrogen fertilization promoted the development of the two varieties of corn studied. It was found that the split, performed in six applications, provided greater vegetative and reproductive development of the corn varieties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
