13. Effects of ensiling density on nutritive value of maize and sorghum silages
ABSTRACT Studies were conducted to determine the effects of different ensiling densities on fermentation, aerobic stability, and nutritive value of maize and sorghum silages. Maize and sorghum were harvested at dough (363 g/kg) and milk stages (275 g/kg), respectively. Herbages were chopped approximately 1.5 cm after harvest and then ensiled in mini silos at

14. Determination of optimum levels of nitrogen, phosphorus and potassium of oil palm seedlings in solution culture
Balanced nutrient elements in fertilizer play a critical role in oil palm seedling successful growth and development, and at the same time reduces of fertilizer losses in the environment. This study examines the effect of different levels of N, P2O5 and K2O for oil palm seedlings in solution culture on growth traits, nutrient uptake in plant tissues and biom

15. Demanda de potência do motor hidráulico do extrator primário da colhedora de cana-de-açúcar / Power demand in the hydraulic motor of primary extractor of the sugar cane harvester
The growing demand of sugar cane and the need for agility in the processing of this product, the agricultural sector led to seek cropping systems with greater capacity in the field. However, the sugar cane harvesters still have some critical points depending on the quality of work due to various types of product losses during harvest. Most of the deficiencie

16. Identification of SNPs in RNA-seq data of two cultivars of Glycine max (soybean) differing in drought resistance
The legume Glycine max (soybean) plays an important economic role in the international commodities market, with a world production of almost 260 million tons for the 2009/2010 harvest. The increase in drought events in the last decade has caused production losses in recent harvests. This fact compels us to understand the drought tolerance mechanisms in soybe

17. ASPECTOS DO CONTROLE BIOLÓGICO DE Botrytis cinerea Pers. Ex. Fr. EM VIDEIRA / ASPECTS OF Botrytis cinerea Pers. Ex. Fr. BIOLOGICAL CONTROL ON GRAPEVINE
Rio Grande do Sul (RS), the most important state of grape production in Brazil, harvests, approximately, 780 thousand tons annually. One of the biggest constraint factors to the obtainment of higher production numbers is the incidence of late season diseases in vineyards, being botrytis bunch rot, caused by Botrytis cinerea, one of the major contributors for

18. Predição e identificação de danos internos em batatas por meio do biospeckle laser / Prediction and identification of potatoes in internal damagethrough the laser biospeckle
Food damages due to mechanical impacts at post harvest different phases are one of the biggest issues faced by food industry. In potatoes, productivity decrease due to impacts and physical damages can get to 40% during processing, storage, transportation and commercialization phases. Intern injuries, or bruising, are one of the biggest factors losses at pota

19. Leaching of nitrogen, potassium, cacium and magnesium in a sandy soil cultivated with sugarcane.
A lysimeter experiment was carried out with sugarcane aiming to evaluate the leaching of nitrogen derived from either urea (15N) or the soil/sugarcane crop residues. The leaching of K+, Ca2+, and Mg2+ was also evaluated. The experiment was a factorial 2x4. The influencing factors were: firstly, the differential addition of two kinds of sugarcane remains to t

20. Controle da velocidade e da direção entre dois veículos agrícolas / Speed and steering control between two agricultural vehicles
One problems of the mechanical harvest of sugar cane is the lack of synchronization between the harvester and field wagon. This problem can causes crop losses as well as reducing operational capacity. The first occurs when the machines are misaligned and part of the sugar cane is thrown out of the wagon. The operational capacity reduce occurring when the mac

21. Efeito de métodos de propagação no desenvolvimento de doenças e na produtividade de um clone de maracujazeiro-azedo.
RESUMO: As doenças causadas por patógenos do solo provocam perdas expressivas em maracujazeiros comerciais. A utilização de porta-enxertos resistentes pode ser uma das alternativas para o controle dessas doenças. A Passiflora nitida é uma das espécies de Passifloraceae que apresentam resistência a essas doenças, mas suas sementes geram porta-exertos

22. Efects of vibration on quality of pot lities / Efeito da vibração na qualidade de lirios orientais em vaso
In Brazil losses of agricultural products during production and commercialization can reach up to 30% due to mechanical damages during harvest, transportation and storage, resulting in non-commercial quality products. The inadequate conditions of transport are related to lack of awareness of most chain segments, roads in bad conditions, drivers proper traini

23. Avaliação agronômica da cana-de-açúcar submetida a métodos de colheita para produção animal / Agronomic traits of sugarcane (Saccharum spp.) under different harvesting methods for animal production
This research aimed to study harvesting losses, morphologic composition, dynamics of tillering and accumulation and, tiller density of sugarcane IAC86-2480 variety under three harvesting methods. In manual harvesting (MAN), plants were harvested to ground level, using a cutter. For mechanical harvesting (MEC), the harvester (adjusted for 20 cm from the groun

24. Dry spells occurrence in the northwest portion of Rio Grande do Sul state between the years 1978 and 2005 and its association to the climatic conditions in the atmosphere / Veranicos ocorridos na porção noroeste do estado do Rio Grande do Sul entre 1978 e 2005 e sua associação às condições climáticas na atmosfera
Agriculture plays an extremely important role in the economy of Rio Grande do Sul state. The target region of the present work in its northwest portion is represented by six cities: São Luiz Gonzaga, Santa Rosa, Cruz Alta, Iraí, Passo Fundo e Marcelino Ramos. It constitute a national focus of soya production and thus depend heavily on atmospheric condition
