Abstract

Maize is a plant cultivated as fodder or seed. The seeds of this plant are used for poultry and the fresh fodder or silage is required for animal husbandry. In the research, the dual-purpose cropping possibility of maize for fodder and seed harvesting under nitrogen application was assessed. A field experiment and a laboratory experiment were conducted in 2014. The field experiment was performed as a split-plot design. Studied factors were the topping factor (topping (stem removal at the top of the ear) or no topping) and nitrogen fertilizer factor (nitrogen application of 0, 75, and 150 kg ha-1). In the laboratory experiment, germination traits of produced seeds from the maternal plant under topping and nitrogen were studied. Results showed that no topping had the highest ear weight. Topping and nitrogen did not affect seed number per maize ear row. Topping had a lower 100-seed weight and seed yield than no topping. Nitrogen did not affect seed yield and 100-seed weight. Topping and nitrogen application did not affect germination percentage, radical length, caulicle length, and vigor of produced seed at the seed milking stage. Nitrogen application at this stage could not compensate for the damage caused by the topping. Maize topping at the seed dough stage may be evaluated in future studies.

除穗上茎和施氮对饲料和种子两用玉米的影响

玉米是一种作为饲料或种子种植的植物。这种植物的种子用于家禽，新鲜饲料或青贮饲料是畜牧业所需要的。本研究对施氮条件下玉米饲料和种子双重用途种植的可能性进行了评价。2014年进行了野外试验和室内试验。田间试验采用分畦设计。研究因子为打顶因子(打顶(穗顶去茎)或不打顶)和氮肥因子(施氮量分别为0、75和150 kg hm -1)。在室内试验中，研究了在打顶和施氮条件下母株生产的种子的萌发特性。结果表明，未打顶的穗重最高。打顶和施氮对玉米穗行种子数无影响。打顶比不打顶的百粒重和籽粒产量低。施氮对种子产量和百粒重没有影响。灌浆期打顶和施氮对产出种子的发芽率、根长、茎长和活力无显著影响。这一阶段施氮不能弥补顶部造成的损害。在未来的研究中，可以对玉米种子面团阶段的浇头进行评价。

期刊介绍： La Revista Facultad Nacional de Agronomía Medellín (RFNA), de la Universidad Nacional de Colombia, Sede Medellín, Facultad de Ciencias Agrarias, es una publicación científica editada desde el año 1939, en formato impreso y digital y de acceso abierto desde la web —sin costo para autores y lectores—. Está orientada a investigadores que crean conocimiento disciplinar y multidisciplinar que articula la ciencia y la tecnología para hacer más productivo el campo a nivel empresarial y de economía campesina. La Revista tiene como objetivo divulgar resultados de investigación mediante artículos originales, inéditos y arbitrados (peer review) de carácter científico que respondan a preguntas específicas y que proporcionen sustento y pruebas a una hipótesis, en aspectos relacionados con las Ciencias Agronómicas, Producción animal, Ciencias Forestales, Ingeniería Agrícola, de Alimentos y otras afines que contribuyan a la solución de los limitantes del agro a nivel nacional, regional e internacional. La Revista recibe y publica, sin ningún costo, artículos en idioma inglés de investigación, revisión, reseñas y cartas al editor. Desde el 2017 la periodicidad de publicación es cuatrimestral, se publican tres números al año con circulación nacional e internacional, en los siguientes períodos: Enero - Abril Mayo - Agosto Septiembre - Diciembre This journal does not charge APCs or submission charges.
