“…Evaluating the cultivars Tifton-85 and Jiggs fertilized with macronutrients, Rezende et al (2015) observed the highest yields of leaves, stems, tillers, and dry weights when using the fertilizers 20-10-10 and 08-28-16. According to these authors, this fact occurred for the presence of phosphorus in these formulas, once they used the fertilizer 30-00-20, and it limited the yields of leaves, culms, tillers, and dry mass.…”

This paper aims to assess the contribution of basal and aerial tillers to structural and productive characteristics of Tifton 85 bermudagrass, irrigated with fish tank wastewaters and fertilized with NPK. The experiment was conducted in the city of Petrolina-PE, Northeastern Brazil. The evaluated area had 960 m 2 subdivided into five treatments and ten replicates, in a completely randomized design. Treatments consisted of different fertilization rates of NPK (0, 33, 67, 100, and 150%) as recommended by the Handbook of Fertilization Recommendations for the State of Pernambuco, and based on a prior soil analysis. Irrigation water came from fishponds with Nile Tilapia fingerlings. The experiment was divided into four intervals of 27, 29, 18, and 21 days respective to the first, second, third, and fourth cuts. Both tiller types were analyzed for number of individuals, culm length and diameter, fully-and partially-expanded leaves, leaf length and width (fully or partially expanded), dry mass of leaves (fully and partially expanded and total), culm, dead tissue, and total tiller, and the ratio of leaf and culm. Both structural and productive characteristics showed a linear growth trend for both types, with emphasis on the basal tillers. Thus, a suitable supply of nutrients is crucial for grasses, mainly NPK, as these are macronutrients of vital importance in physiological processes. In addition to the nutrients supplied via fish farming wastewater, fertilization with 150% of the recommended amount of NPK promoted a greater structural development of the tillers, increasing their productivity levels. ResumoEste trabalho teve como objetivo avaliar a contribuição dos perfilhos basais e aéreos do capim-tifton 85, nas suas características estruturais e produtivas, quando irrigado com efluentes de tanque de piscicultura e recebendo adubação com NPK. O trabalho foi conduzido no município de Petrolina-PE, e a área útil utilizada foi de 960 m 2 dividida em cinco tratamentos e dez repetições, em delineamento experimental inteiramente casualizado. Os tratamentos foram compostos por diferentes níveis de adubação com NPK (0, 33, 67, 100 e 150%) conforme recomendado pelo manual de análise de solo do estado de Pernambuco-PE, sendo que antes das adubações foram realizadas as análises do solo. A água para irrigação foi oriunda de tanques de piscicultura povoados com alevinos de Tilápia do Nilo. O experimento foi dividido em quatro intervalos com 27, 29, 18 e 21 dias para o primeiro, segundo, terceiro e quarto corte, respectivamente. As variáveis analisadas foram: número de perfilhos basais e aéreos, comprimento e diâmetro do colmo, número de lâmina foliar expandida e em expansão, comprimento e largura de lâmina foliar expandida e em expansão das duas categorias de perfilhos, além da massa seca da lâmina foliar expandida, em expansão e total, do colmo, tecido morto e por unidade de perfilho, assim como a relação lâmina foliar/colmo dos dois tipos de perfilhos, basal e aéreo. Verificou-se crescimento linear das características e...

“…Additionally, low phosphorus (P) availability in the soil decreases root development and plant tiller number, demonstrating the importance of this nutrient in pasture plantations (Rezende et al, 2011). Deficiencies of these nutrients can also affect the chemical composition of plants (Dupas et al, 2016a;Rabêlo et al, 2013;Rezende et al, 2015).…”

“…Thus the use of fertilizers can contribute to increase pasture production (Rezende et al, 2015). An adequate proportion between N and potassium (K) is important for plant growth, since K is the second nutrient most extracted by forage and participates in enzymatic processes and protein synthesis in plants (Rabêlo et al, 2013;Rezende et al, 2015).…”

“…These effects show the importance of fertilizer utilization in pastures, but the understanding of how the combination of nutrients can affect production and nutritive value of grasses needs to be better investigated (Dupas et al, 2016a). Furthermore, the DMP and chemical composition of forages varies with soil type, amount and type of fertilizer, genetic differences between cultivars and interval between cuts (Dupas et al, 2016a;Rezende et al, 2015). Therefore, the knowledge generated through research, especially that resulting in new technology, can be adopted when the competitive edge is greater in comparison to already existing alternatives and when prices are beneficial, implying higher production of forage in an efficient way (Rodrigues et al, 2015).…”

“…However, the high cost associated with the low use efficiency leads to a reduction of fertilizer utilization in areas occupied by pastures (Barcellos et al, 2008;Dupas et al, 2016a,b). In consequence, the lack of fertilizer utilization combined with low fertility levels in tropical regions determine the beginning of soil degradation processes, reducing the productivity efficiency of pastures (Dupas et al, 2016a,b;Rezende et al, 2015).…”

Several fertilizers with different efficiency and price are commercially available to increase the yield of pastures, generating doubts about which should be chosen for fertilization, especially regarding short term operation returns. Our objective was to investigate the effect of simple and compound fertilizers on the production, chemical composition and economic parameters of Marandu and Xaraes palisade grass in the short term. The fertilizers Urea, Super N, were evaluated in three cuts of the pasture. The overall rate of tiller occurrence, dry matter production, crude protein content, total digestible nutrients and digestible energy of Marandu palisade grass increased with the supply of nitrogenous fertilizers, while neutral detergent fiber (NDF), acid detergent fiber and hemicellulose content decreased. Fertilization using Super N resulted in higher production of mass per kilogram of fertilizer applied and per unit of real (R$) invested per hectare. The number of tillers of Xaraes palisade grass increased and NDF content decreased with the application of 20-10-10. Fertilization of Marandu palisade grass with Super N is more efficient from the economic and productive point of view than fertilization with urea. Comparing the grasses, Xaraes is more demanding in phosphorus and potassium than Marandu.Key words: chemical composition; morphological characteristics; production cost.

BACKGROUND: Several factors may degrade pastures, in particular, inadequate nutrient application and spittlebug attacks. Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae), one of the species that occur in Brazil, is a limiting pest in forage production. This study analyzes the influence of fertilization with the macronutrients nitrogen, phosphorus and potassium (NPK) on the survival of M. spectabilis nymphs, and the effects of damage by nymphs and adults on the production, quality and regrowth capacity of the forages Brachiaria ruziziensis, Pennisetum purpureum and Digitaria sp. RESULTS: Fertilization of the forages differentially affected damage due to spittlebug herbivory. Attacks by nymphs and adults decreased chlorophyll content, plant regrowth and forage quality, and increased injury, regardless of fertilization. The availability of nutrients in the soil not only decreased fiber content, but also increased crude protein, chlorophyll content and regrowth, even when pest infested. Soil fertilization increased the capacity of forage plants to lessen, albeit not eliminate, the effects of injury by M. spectabilis. CONCLUSION: Forages in fertilized soil are more tolerant to attacks by M. spectabilis nymphs and adults.
