Resumo: The use of manual traction seeders in small farms has technical and economic feasibility, but few studies are carried out with this sowing technology for cowpea, which is one of the main crops in the Cariri region of Ceará. This study aimed to evaluate the longitudinal spacing and yield of cowpea as a function of speed and working depth of a manual seeder. The study was conducted at the Center for Agricultural Sciences and Biodiversity, Federal University of Cariri, Crato-CE, located in the region of Cariri, Ceará. The experiment was arranged in a 2x3 factorial randomized block design, with four replications, totaling 24 observations. The first factor was two sowing depths (Shallow and Deep); and the second factor the displacement speed (2.15; 3.90; and 4.71 km h-1). The initial and final population, survival rate, longitudinal spacing, number of pods per plant, number of beans per pod, bean yield at 11% moisture, and green pod yield were analyzed. The results showed higher values of faulty spacings and lower values of acceptable spacings by using the shallow depth and the higher speeds, with consequent reduction in the final population. However, as cowpea produced side branches and increased production per plant, the yield results were not influenced by depth and working speed.

Neste sentido, o objetivo do presente artigo foi avaliar o espaçamento longitudinal e a produtividade de feijão caupi em função da velocidade e profundidade de trabalho de uma semeadora manual. O estudo foi conduzido no Centro de Ciências Agrárias e da Biodiversidade, da Universidade Federal do Cariri, Crato-CE. O delineamento adotado foi em blocos casualizados, em esquema fatorial 2x3, com quatro repetições, totalizando 24 observações. O primeiro fator foram duas profundidades de semeadura (menor: 1 cm e maior: 2 cm); e o segundo a velocidade (2,15; 3,90 e 4,71 km h-1). Foram analisadas a população inicial e final, o índice de sobrevivência, o espaçamento longitudinal, o número de vagens por planta e de grãos por vagem, a produtividade de grãos a 11% de umidade e a produtividade de vagens verdes. Os resultados evidenciaram maiores valores de espaçamentos falhos e menores de aceitáveis com o uso da menor profundidade e das maiores velocidades, com consequente redução na população final, porém, em função do feijão caupi produzir ramos laterais e aumentar a produção por planta, os dados de produtividade não foram in?uenciados pela profundidade e velocidade de trabalho.Universidade Federal de Viçosa - UFV2017-12-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/67410.13083/reveng.v25i6.750Engineering in Agriculture; Vol. 25 No. 6 (2017); 500-508Revista Engenharia na Agricultura - REVENG; v. 25 n. 6 (2017); 500-5082175-68131414-398410.13083/reveng.v25i6reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/674/pdfPinto, António AlvesCamara, Felipe Thomaz daSilva, Francisco Edson daSantana, Laudeline DantasRodrigues, Wíctor Állyson Diasinfo:eu-repo/semantics/openAccess2023-01-19T13:33:21Zoai:ojs.periodicos.ufv.br:article/674Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:33:21Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
