RESUMO – A maior parte do nitrogênio (N) é absorvida pela cultura do milho na forma de nitrato (NO3 -), que é reduzido na planta pela ação da enzima nitrato redutase, a qual tem o molibdênio (Mo) como um dos principaisconstituintes. O objetivo deste trabalho foi avaliar doses de N em conjunto com Mo na cultura do milho irrigado, cultivado em sistema plantio direto. O experimento foi desenvolvido no município de Selvíria, MS. O delineamento utilizado foi o de blocos casualizados em parcelas subdivididas com quatro doses de N (0, 90, 135 e 180 kg ha-1) e cinco doses de Mo (0, 10, 20, 30 e 40 g ha-1), com quatro repetições. Foram avaliados atributos morfológicos e produtivos da cultura. A maior produtividade de milho foi obtida com 180 kg ha-1 de N e com 25,6 g ha-1 de Mo.Palavras-chave: adubação nitrogenada, micronutriente, plantio direto, Zea mays L.NITROGEN AND MOLYBDENUM FOR IRRIGATED MAIZE IN THE BRAZILIAN SAVANNAH WITH LOW ALTITUDEABSTRACT – Most of nitrogen (N) is absorbed by maize as nitrate (NO3-), that is reduced in the plant by the actionof the nitrate reductase enzyme, which has molybdenum (Mo) as a major component.

Field experiments were conducted to determine the effects of tillage system and rimsulfuron application on weed flora and growth of maize (Zea mays L. Mitic F1) at a site with no history of pesticide use for the last 5 years. A randomized complete block design was employed with three replicates per treatment (conventional tillage without rimsulfuron application (control), no-tillage with rimsulfuron application (NT+Rim) and conventional tillage with rimsulfuron application (CT+Rim)). The lowest leaf area index, dry weight and yield of maize were recorded in NT+Rim plots. In addition, the highest soil bulk density was determined in NT+Rim plots. Moreover, the rimsulfuron application resulted in significant reduction in the root growth and arbuscular mycorrhizal (AM) colonization. The lowest root biomass, root length density, root surface and AM root colonization was found in CT+Rim plots. The lowest weed number and biomass was also observed at CT+Rim plots. Sustainability yield index (SYI) shown that the maize crop is more stable under conventional tillage compared with no-tillage. Our results indicated that root growth was reduced significant by rimsulfuron application but statistically significant lower maize yield was obtained in no-tillage system.

[email protected]     1 RESUMO   O objetivo do trabalho foi avaliar o efeito de diferentes coberturas vegetais sobre o crescimento e produção de biomassa de milho para produção de silagem em sistema de cultivo irrigado por gotejamento. O experimento foi conduzido durante o ano agrícola de 2019, em um Neossolo quartzarênico argiloso, na área experimental da Fazenda Escola da IF Goiano Campos-Iporá. O delineamento experimental utilizado foi o de blocos casualizados, sendo cinco tratamentos e quatro repetições. Os tratamentos empregados foram: T1) Área em pousio, T2) Crotalária, T3) Mavuno, T4) Lab-lab, T5) Aries. Aos 88 dias após a semeadura, quando as plantas de milho atingiram o ponto de corte para produção de silagem, foram avaliados diâmetro de colmo, altura de inserção da primeira espiga, número de espigas, diâmetro e comprimento das espigas. Os resultados foram submetidos a análise de variância e ao teste de Tukey a 5% de significância. Os adubos verdes apresentaram diferença no desenvolvimento do milho quando comparados com área em pousio, os adubos verdes que apresentaram maiores efeitos foram o capim Mavuno e a Crotalária.   Keywords: Zea mays L., Capim Mavuno, Crotalaria spectabilis     VIEIRA FILHO, W.

EFFECTS OF GREEN MANURES IN IRRIGATED CORN UNDER NO-TILLAGE     2 ABSTRACT   The work aimed to evaluate the effect of different green manure on the growth and production of corn biomass for silage production in the drip-irrigated cultivation system. The experiment was conducted during the 2019 agricultural year, in a Neossolo quartzarênico argiloso in the experimental area at Farm School of IF Goiano Campos-Iporá. The experimental plot used was randomized blocks, with five treatments and four replications. The treatments used were T1) Fallow, T2) Crotalária, T3) Mavuno, T4) Lab-lab, T5) Aries. Field evaluations were made 88 days after emergence: height of insertion of the first ear, number of ears, stem diameter. The results were subjected to analysis of variance and Tukey's test at 5% significance. The green manure difference in the development of the corn when compared with fallow area, the green manures that dissipate the greatest effects were Mavuno grass and Crotalária.   Keywords: Zea mays L., Capim Mavuno, Crotalaria spectabilis

Mechanical soil management has a huge impact on early plant development and can promote effects at all stages of the silage forage production cycle. Thus, this work was conducted to verify if a mechanized system of soil preparation influences the accumulation of pigeon pea and corn biomass. The experiment was conducted at the farm school of Federal University of Mato Grosso do Sul, Faculty of Veterinary Medicine and Animal Science. The experimental delimitation chosen was randomized blocks, the treatments were two systems of tillage (conventional and reduced), associated to two crops (Cajanus cajan L., cv. BRS Mandarim e Zea mays L. hybrid TG Status). The cv. BRS Mandarim in conventional tillage system impacted higher biomass values. In addition, the same soil preparation system promoted oscillations between the crops (P<0.05), where cv. BRS Mandarim showed biomass values 7% higher than cv. Status TG. In reduced handling system, the crops presented the same biomass productivity. Despite the increase of dry weight during the cycle of cv. BRS Mandarim biomass production, there was a reduction in the dry matter fraction, indicating that the specific weight per plant decreased at the end of the evaluation period. The tillage system that was fulfilled conventionally promoted higher estimates of pigeon pea biomass. Corn was not influenced by mechanized tillage system.
