| description | Increasing maize yield per unit is the most important measure to address food security issues. Farmers from northeastern China created several cropping patterns to increase maize yield per unit, but which pattern is the best has not been researched systemically. A randomized block design of six cropping patterns and four replicates was used. Six cropping patterns 65cm×65 cm, 40cm×90 cm, 30cm×100 cm, 20cm×110 cm, 2L:0 and 4L:0 respectively were studied. The results showed that all wide and narrow rows patterns and free-sow patterns have higher yield than same spacing patterns, and 30cm×100cm is the optimal pattern to obtain the highest yield followed by 20cm×110cm, 4L:0, 2L:0, 40cm×90cm and 65cm×65cm respectively. According to our survey, more than four-fifths is the same spacing pattern (65cm×65cm) whose yield was 1.5t·ha-1 lower than wide and narrow rows with 30cm×100cm, so if all farmers carried out the 30cm×100cm pattern, food security of China problems will be obviously improved. |

Efeitos de diferentes práticas de cultivo na produtividade domilho em Lishu, ChinaResumoO aumento de rendimento de milho por unidade é a medida mais importante para solucionarproblemas de segurança alimentar. Agricultores do nordeste da China criaram várias práticasde cultivo para aumentar o rendimento por unidade, mas qual pratica é a melhor ainda não foipesquisado. Um delineamento de blocos casualizados de seis padrões de cultivo e quatro repetiçõesfoi utilizado. Seis padrões de cultivo 65 cm × 65 cm, 40 cm × 90cm, 30cm × 100 cm, 20 cm × 110 cm, 2L:0 e 4L: 0, respectivamente, foram estudados. Os resultados mostraram que todas as praticas largas eestreitos em linhas e livres de padrões de semeadura têm maior rendimento o que os padrões de mesmoespaçamento, e 30cm × 100 cm é o padrão ideal para obter o maior rendimento, seguido por 20 cm ×110 cm, 4L: 0, 2L: 0 , 40cm x 90cm e 65 cm × 65 cm, respectivamente. Se todos os agricultores realizassemo padrão de 30cm × 100cm, problemas na segurança alimentar da China seriam melhorados. 2011-12-19 2022-03-21T20:06:56Z 2022-03-21T20:06:56Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://comunicatascientiae.com.br/comunicata/article/view/64 10.14295/cs.v2i3.64 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/77505 por https://comunicatascientiae.com.br/comunicata/article/view/64/86 application/pdf Federal University of Piauí Comunicata Scientiae; Vol. 2 No. 3 (2011); 160-163 Comunicata Scientiae; v. 2 n. 3 (2011); 160-163 2177-5133 2176-9079 |
