“…The more digestible product, which had lower ADF (35.30%), NDF (55.82%) was "Hay day". The findings of Holman et al (2019) and Damian et al (2017) about increasing CP content with applied N rates showed similar trends to the current study. CP contents were also documented by Celik and Turk (2021) In the current study, there were variations among N fertilizer rates [N0 to N2 (0 to 180 kg ha -1 )] in digestibility parameters, which were ADF, NDF, and ADL.…”

The study aimed to observe the effects of two forage sorghum hybrids and different nitrogenous (N) fertilizer rates. The current study was set up in randomized complete block (RCB) as a split-plot design with triplicate at the Field Crops Department experimental area, University of Ankara in the 2022 summer season. This experiment included two treatments which had forage sorghum hybrids (Hay day and Super-graze) and nitrogen fertilization rates in the form of 18% ammonium sulfate [control group with no nitrogen (N0), 120 kg ha-1 N (N1), 180 kg ha-1 N (N2)]. N fertilizing rates positively influenced in agronomic profiles, yield components and nutritive profiles. The plant height (197.24-221.72 cm), green herbage yield (GHY) (60.42-70.89 ton ha-1), dry matter (DM) yield (17.77-23.98 ton ha-1), crude protein (CP) yield (0.97-1.90 ton ha-1), metabolic energy (ME) yield (33070.17-51840.85 Mcal ha-1), net energy production (NEp) yield (21164.91-33178.15 Mcal ha-1) increased with applied N rates. The maximum of DM (33.83%), CP (7.90%), TDN (58.63%), ME (2.16 Mcal kg-1 DM), NEp (1.80 Mcal kg-1 DM), and the minimum of ADF (33.09%), NDF (53.17%), ADL (5.14%) were obtained in N2 rates. In light of the results; “Hay-day” had more GHY. “Sugar-graze” had more DM yield and it was determined more digestible forage. It was inferred that the best yield components and nutritive profiles were obtained in N2 rate.

“…Among other factors, the main reasons for this scenario are the low consumption and the inadequate application of fertilizers. In addition, little is known about the patterns of nutrient absorption and accumulation in sorghum (Damian et al, 2017).…”

-The present study aimed to determine the curves of macronutrients and dry matter accumulation in grain sorghum DKB 599, grown in a semiarid region. A field experiment was conducted on a sandy loam eutrophic red Latosol (Oxisol) in Janaúba, State of Minas Gerais (MG), Brazil, in a randomized block design with four replications.As statistical method, a nonlinear regression, sigmoidal function with three parameters was used. After drying, the plants were weighed and ground to determine N, P, K, Ca, Mg and S concentration. Grain sorghum plants accumulate nutrients in their shoots in the following order: N> K> Ca> P> Mg> S. The highest concentrations of K and N were observed in stems and grains, respectively. In the conditions of this experiment, the most favorable time to perform nitrogen and potassium topdressing fertilization is when the plants present seven fully expanded leaves or 24 days after the emergency (DAE).Keywords: fertilization, growth, nutrition, Sorghum bicolor. ABSORÇÃO DE MACRONUTRIENTES E ACÚMULO DE MATÉRIA SECA NO SORGO GRANÍFERORESUMO -Este trabalho teve como objetivo determinar as curvas de acúmulo de matéria seca e macronutrientes no sorgo DKB 599 cultivado em região semiárida. O experimento foi conduzido em campo sobre um Latossolo Vermelho eutrófico, de textura franco-argilosa, no município de Janaúba-MG, Brasil, em delineamento experimental de blocos casualizados, com quatro repetições. Utilizou-se o modelo de regressão não linear, função sigmoidal com três parâmetros como método estatístico. Após secagem, cada parte da planta foi pesada e moída para, em seguida, determinarem-se os teores de N, P, K, Ca, Mg e S. As plantas de sorgo granífero acumulam nutrientes em sua parte aérea na seguinte ordem: N > K > Ca > P > Mg > S. As maiores concentrações de K e N foram observadas, respectivamente, nos caules e nos grãos. Nas condições de condução do experimento, a época mais propícia para realizar a adubação nitrogenada e potássica em cobertura é quando as plantas apresentam sete folhas totalmente expandidas ou 24 dias após a emergência (DAE).Palavras-chave: fertilização, crescimento, nutrição, Sorghum bicolor.

“…For Mascarello & Zanão Júnior (2015), nitrogen is one of the nutrients that have more expressive effects in maize yield increase, thus influencing leaf N content (Minato et al, 2017), grain protein content (Mascarello & Zanão Júnior, 2015), crude protein concentration, and shoot dry mass yield for silage (Damian et al, 2017).…”

Cover crops can contribute differently to the supply of nitrogen to crops. The objective was to evaluate the response of maize to nitrogen doses (0, 70, 140, 210 and 280 kg ha-1) when grown in succession to cover crops (vetch, forage turnip, black oat, ryegrass and fallow). The randomized block experimental design was used, with subdivided plots and four replications. Cover crops were allocated into plots, and N doses into sub-plots. As to cover crops, the aspects evaluated were phytomass production, N content and total accumulated; with regard to maize, the aspects evaluated were SPAD (Soil Plant Analysis evelopment) index, leaf N content, total grain protein, yield and agronomic efficiency of N. Black oat, ryegrass and forage turnip presented higher phytomass production. All species had similar results as to the total N accumulated in the aerial part (average value of 91.06 kg ha-1). In succession to black oat, ryegrass and fallow period, N doses up to 140 kg ha-1 applied in maize result in higher yield and better agronomic efficiency of nitrogen use. Without application of nitrogen (0.0 kg ha1), forage turnip and vetch provided higher total protein content in the grain, yield over 8,550 kg ha-1, and less agronomic efficiency of nitrogen use.
