| ABSTRACT: Nitrogen (N) is the main nutrient responsible for the green coloration of lawns but also stimulates the growth of the aerial portion of grass, thus increasing mowing expenses. Therefore, herbicides may be used as a growth regulator. The ideal herbicide will reduce lawn height without affecting esthetics. Toward this end, the aim of the present study was to evaluate the green coloration of Emerald grass ( Zoysia japonica Steud.) under the effect of different N doses or herbicides used as growth regulators. The study site consisted of randomized blocks containing 20 treatments arranged in a 5×4 factorial design with four treatment groups: four herbicides (glyphosate, imazaquin, imazethapyr, and metsulfuron-methyl, accounting for 200, 420, 80, and... |

| ABSTRACT: Nitrogen fertilization and an appropriate cutting thickness can result in firmer sod that can be handled in less time with greater turfgrass regrowth during the subsequent cycle. This experiment was conducted on a sod production farm located in Capela do Alto, in the state of Sao Paulo, Brazil. The soil was a dystrophic Rhodic Hapludox (Oxisol) with a medium texture. The experiment had two statistical designs; the initial design was randomized blocks with seven treatments and four replicates. Treatments were five doses of liquid organo-mineral fertilizer (OMF) corresponding to 0, 100, 200, 300 and 400 kg ha−1 of nitrogen (N) with supplementation of phosphorous (P) and potassium (K) as well as two control treatments - one with 300 kg ha–1 of N as... |

| Com objetivo de avaliar o efeito do lodo de esgoto na formação e qualidades de tapetes de grama, foi instalado, em Itapetininga, São Paulo (SP), o experimento utilizando grama Zoysia japonica Steud., conhecida como esmeralda. O delineamento experimental utilizado foi o de blocos ao acaso em parcelas subdivididas, com quatro repetições, sendo as parcelas principais constituídas de cinco doses de lodo (0, 10, 20, 30 e 40Mg ha-1, base seca), mais um tratamento com NPK, de acordo com as necessidades da cultura e as subparcelas com dois sistemas de manejo (com e sem o uso de escarificador utilizado para romper uma camada superficial compactada). Utilizou-se o lodo da Estação de Tratamento de Esgoto de Jundiaí, SP. As doses de lodo aplicadas correspondem às... |
