“…In these four crops, increases in dry matter were between 43.4 % and 109.6 %, if compared to the dose of zero N, and the maximum dry matter yield varied between 21,015 kg ha -1 and 25,533 kg ha -1 . These yields are similar to those obtained by Oliveira et al (2010), in maize and sorghum for silage.…”

“…The difference in dry matter production between the two years of cultivation was 15,087 kg ha -1 . Normally, the dry matter yield in sorghum was higher than that obtained in 2015 (Oliveira et al 2010, Franco 2011. The occurrence of drought between March and April, with periods of 21 and 12 days with no rainfall in the respective months, may also have affected the initial growth of the sorghum plants, despite the high resistance of sorghum to drought (Księżak et al 2012).…”

“…The response to phosphorus fertilization from the third crop shows that the soil P stocks can be depleted rapidly during the course of cultivation, given the high rate of nutrient export by the removal of forage plant biomass in the silage production (Oliveira et al 2010). This suggests that phosphorus fertilization should be prioritized in areas of silage production, similarly to nitrogen fertilization, since year-on-year fertilization probably increased the nutrient absorption and use efficiency by plants (Dovale & Fritsche-Neto 2013).…”

“…Os solos utilizados no sistema de sucessão de milho e sorgo para silagem apresentaram níveis "muito altos" de P e K. Portanto, a adubação com P não teve efeito sobre a produção de matéria seca ou proteína bruta no primeiro ano de cultivo, assim como ocorreu para a adubação com K durante as cinco safras sucessivas. (Oliveira et al 2010, Silva et al 2005a). However, in spite of existing specific fertilization recommendations for the silage production in these crops, which demand large amounts of nutrients (CQFS-RS/SC 2004), in many areas these recommendations are not adopted or are based on recommendations for grain production.…”

Maize and sorghum are the main raw materials in the production of silage for animal feed, with mineral fertilization being worthy of note when the goal is to increase gains in the amount and quality of the forage. This study aimed at evaluating the contribution of N, P or K doses to the dry matter and crude protein yield in maize and sorghum grown for silage. The experiments were carried out in a randomized block design, with four replications, during five successive crops of maize (three summer seasons) and sorghum (two off-season). Five doses of N (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1), five doses of P2O5 (0 kg ha-1, 40 kg ha-1, 80 kg ha-1, 120 kg ha-1 and 160 kg ha-1) and five doses of K2O (0 kg ha-1, 30 kg ha-1, 60 kg ha-1, 90 kg ha-1 and 120 kg ha-1) were applied to each crop in the same experimental area. The N doses contributed to an increase in the crude protein yield in the five successive crops of maize and sorghum, together with an increase in dry matter and/or protein concentration. Crude protein increased 59.5-312.9 % for both crops. The soils used for the succession cropping system of maize and sorghum for silage had "very high" levels of P and K. Therefore, the P fertilization had no effect on the dry matter or crude protein yield in the first year of cultivation, similarly to the K fertilization during the five successive crop seasons.

“…The yield of the sunflower forage is good, achieving equal or superior yield in relation to the maize. OLIVEIRA et al (2010), studying different species of forages (maize, sorghum-Sudan, forage sorghum and sunflower) verified that the greater productions of green weight were of the forage sorghum and of the sunflower, with 82 and 83.9 tons per hectare, even with the high amount of green weight, the dry weight was below the other forages, due to the stage of early harvest, with 19% of DW. On average, when the planting season was observed, it was verified that the sowing in December provided higher contents of DW in relation to October and November, and also had greater participation of the capitulum in the silage mass 61.1%, 47.3% and 58.1%, respectively (MELLO et al, 2006).…”

Silage of quality is required by farmers for providing significant increases in productivity and maximizing the profitability of the productive system, being the sunflower crop (Helianthus annuus L.) an option for this purpose. The aim of this review was to discuss aspects about genetic characteristics linked to improvement of the sunflower for the production of whole plant silage. The genetic breeding of sunflower has got proportions after the discovery of cytoplasmic male sterility and of the restoration gene. The sunflower crop presents good forage potential and should be used in addition to corn silage. There are genetic resources for the breeding of the bromatological characteristics of the crop for forage production. As a rustic plant, the sunflower can be grown in regions or seasons which have risk of water shortages, generating income and enhancing the use of the land.Keywords: Bromatological characteristics; heritability, hybrids; lines; cytoplasmic male sterility. Caracteristicas genéticas do girassol (Helianthus annuus L.) visandomelhoramento para silagem de planta inteira ResumoSilagens de qualidade são requeridas pelos agricultores por propiciar significativos incrementos na produtividade e maximizar a rentabilidade do sistema produtivo, sendo a cultura do girassol (Helianthus annuus L.) uma opção para este fim. O objetivo desta revisão foi abordar aspectos sobre características genéticas ligadas ao melhoramento do girassol para produção de silagem de planta inteira. O melhoramento genético do girassol ganhou proporções após a descoberta da macho-esterilidade citoplasmática e do gene de restauração. A cultura do girassol apresenta bom potencial forrageiro, devendo ser utilizada em complemento a silagem de milho. Há recursos genéticos para o melhoramento das características bromatológicas da cultura para a produção de forragem. Por ser uma planta rústica o girassol pode ser cultivado em regiões ou épocas que tem risco de déficit hídrico, gerando renda e potencializando o uso da terra.Palavras chaves: características bromatológicas; herdabilidade; híbridos; linhagens; macha-esterilidade citoplasmática.

The use of waste arising from agroindustrial activities, such as cassava wastewater, has been steadily implemented in order to reduce environmental pollution and nutrient utilization. The aim of this study is that the changes in chemical properties of dystrophic red-yellow latosol (oxisol) were evaluated at different sampling times after reuse of cassava wastewater as an alternative to mineral fertilizer in the cultivation of sunflower, hybrid Helio 250. The experiment was conducted at the Experimental Station of the Agricultural Research Company of Pernambuco (IPA), located in Vitória de Santo Antão. The experimental design was randomized blocks with 6 × 5 subplots; six doses of cassava wastewater (0; 8.5; 17.0; 34.0; 68.0; and 136 m3 ha−1); and five sampling times (21, 42, 63, 84, and 105 days after applying the cassava wastewater), with four replications. Concentrations of available phosphorus and exchangeable potassium, calcium, magnesium and sodium, pH, and electrical conductivity of the soil saturation extract were evaluated. Results indicate that cassava wastewater is an efficient provider of nutrients to the soil and thus to the plants, making it an alternative to mineral fertilizers.
