“…The maximum agronomic efficiency was 4,360 kg ha -1 , using a dose of 8.0 Mg ha -1 . Similar results were observed by Soratto et al (2007), who used mineral fertilization with N in proso millet. They also observed a quadratic response in grain yield, which was maximum under a dose of 120 kg ha and 417.8 kg ha -1 of N were respectively applied, considering that around 48 % of the N present in PSC was mineralizable (Table 2).…”

This compost contains higher N content, when compared to the maximum dose of 120 kg ha -1 used by Soratto et al (2007). For the 2014 experiment, proso millet grain yield responded linearly to PSC doses (Figure 2b), with the highest value observed for the dose of 12.0 Mg ha -1 (2,309 kg ha -1 ).…”

With the intensification of pig farming systems, in Brazil, the production of swine waste has increased considerably, leading to water and soil contamination, due to its improper release. Pig slurry composting is an alternative that can be used in order to avoid or reduce negative impacts, especially for producers with physically limited farm areas, or those who intend to increase the number of animals in their production units. This study aimed at evaluating the influence of pig slurry compost doses on the agronomic characteristics and grain yield of proso millet. A randomized blocks design experiment was installed with four replications and five treatments: control without fertilization, control with mineral fertilizer (NPK) and pig slurry compost doses (4.0 Mg ha-1, 8.0 Mg ha-1; 12.0 Mg ha-1). The pig slurry composting increased the dry matter yield, number of grains per plant and grain yield of proso millet, when compared to the control with or without mineral fertilizer. The proso millet yield, at the doses of 8.0 Mg ha-1 and 12.0 Mg ha-1 of pig slurry, was superior than for both the control without fertilization and the control with the recommended mineral fertilizer, with the latter reaching a maximum agronomic efficiency at the dose of 8.0 Mg ha-1.

“…The linear increase in plant height as a function of N rates are in line with findings reported for wheat (ZAGONEL & FERNANDES, 2007), rice (BUZETTI et al, 2006) and millet (Panicum miliaceum L.) (SORATTO et al, 2007). Nitrogen is known to stimulate vegetative growth and stem elongation.…”

The objective in this study was to evaluate the effects of nitrogen rates in association with rates of the growth retardant trinexapac-ethyl on wheat. The experiment was conducted in Viçosa, MG and arranged in a 5×4 factorial, randomized block design, with four repetitions. A combination of five nitrogen rates (30, 60, 90, 120 and 150kg ha -1 ) with four rates of trinexapac-ethyl (0, 62.5, 125 and 187.5g ha -1

“…Soratto et al (2004), estudando Panicum miliaceum observaram aumento na altura de plantas com a aplicação de adubação nitrogenada aos 25 dias após a semeadura, enquanto em estudo posterior, Soratto et al (2007), observaram aumento na altura de plantas independentemente da época de aplicação do nitrogênio.…”

O presente trabalho objetivou avaliar os efeitos de doses crescentes de nitrogênio sobre as características morfogênicas, estruturais e produtivas das gramíneas Panicum maximum cvs. Mombaça e Tanzânia, e Brachiaria sp. Mulato. O experimento foi conduzido em condições de campo. O delineamento experimental utilizado foi de blocos casualizados em esquema fatorial 3x4, com três forrageiras (Panicum maximum cvs. Tanzânia e Mombaça e Brachiaria sp. cv. Mulato), quatro doses de N (0, 40, 80 e 160 kg ha -1 ), com três repetições. Foram avaliados os seguintes parâmetros: produção de massa verde (PMV), produção de massa seca (PMS), altura de planta, porcentagem de massa seca, folhas por perfilho, taxa de acúmulo de massa seca (TAMS) e eficiência de uso de nitrogênio (EUN). Os capins Mombaça e Tanzânia apresentaram resultados semelhantes, e ambos foram superiores ao capim Mulato quanto à produção de matéria verde e seca. As três espécies forrageiras responderam a aplicação de nitrogênio, com aumento na produção de MS, MV, TAMS, altura e número de perfilhos. A eficiência máxima no uso do N foi obtida com a dose de 120 kg ha -1 .

Mulato. The experiment was conducted under field conditions. The experimental design was randomized blocks in a 3x4 factorial design with three forages (Panicum maximum cvs. Tanzania and Mombaca and Brachiaria sp. cv. Mulato), four N rates (0, 40, 80 and 160 kg ha -1 ) with three replications. Were evaluated the following parameters: fresh matter production (FMP), dry matter production (DMP), plant height, percentage of dry matter, leaves per tiller, dry matter accumulation rate (DMAR) and nitrogen use efficiency (NUE). Grasses Mombasa and Tanzania showed similar results, and both were superior
