Smallholder farming in Brazil: An overview for 2014

The goal of this paper is to provide an update on smallholder farming in Brazil. Instead of using data from the last available Agricultural Census (2006), a database from the Ministry of Agrarian Development for 2014 was used. These data are extracted from a tax form called “Declaração de Aptidão ao Pronaf-DAP” (Declaration of Aptitude to Pronaf) that is mandatory for all farmers in...

Exogenous ascorbic acid improved tolerance in maize (Zea mays L.) by increasing antioxidant activity under salinity stress

Salinity causes additional manufacture of reactive oxygen species (ROS) in plants, and ascorbate plays important role in maintaining of ROS scavenging antioxidant enzymes. In this study, the role of exogenous ascorbic acid (AsA) was examined on growth, chlorophyll and oxidative stress related enzymatic and non-enzymatic antioxidants in three maize hybrids under NaCl mediated salt stress. In hydroponic culture, AsA was...

Seasonality influence the nutrient content of litter fall in secondary forest in the Amazonian

Secondary forest vegetation in the Bragantina area, Northeast of Pará State, is characterized by the abandonment of anthropized forests, locally known as capoeiras, in different successional stages. The current study aims to evaluate the nutrient concentrations in order to identify the treatment that have caused greater nutrient deficiency due to full and partial litter spacing well as to assess the capoeira with...

Effect of urea treatment and concentrate mix supplementations on feed intake and digestibility of Horro sheep fed cured maize husk (Zea Mays) at Bako, Western Ethiopia

Feed intake and digestibility experiment were conducted using twenty yearling male Horro sheep weighing 20.42 ± 0.35 kg (mean ± SD). The objectives of the study were to evaluate the response of Horro sheep to feed intake and apparent digestibility when supplemented with different level of noug seed meal and wheat bran mix (1:1) on DM basis. For this study, randomized complete block design was employed....

Towards attaining equity and satisfaction in water allocation mechanism for irrigated agriculture in Northern Nigeria

Mechanism for water allocation in the irrigated agriculture has been subject of conflict and challenges in sub-Sahara Africa (SSA) due to higher input in rice farming and increasing water shortage. How satisfactory is the allocation mechanism by the stakeholders (the providers, policy-makers and the farmers) and how do farmers perceive equity objective on the existing water allocation mechanism in Nigeria? This paper...

Two new wheat varieties for irrigated conditions of Afghanistan

New high yielding and disease resistant wheat genotypes were introduced in 2008-09 crop season through 4th Elite Bread Wheat yield Trial (EBYT) as well as 2nd Stem Rust Resistance Screening Nursery (STEMRRSN). One genotype from EBYT performed 15% higher than commercial variety, Mazar 99 during five years of testing at over eight locations in Afghanistan and was therefore recommended for release for commercial...

Potential of antranilic diamides applied in seeds of soybeans with and without cry1ac protein for Helicoverpa armigera caterpillar control

In Brazil, the caterpillar Helicoverpa armigera (Hübner) is a key economic pest of soybean, from seedling emergence to the reproductive stage. Control of this pest has relied on foliar insecticide sprays, and the use of insect-resistant cultivars. Characterization of the efficacy of insecticides that can be used for seed treatment, as a complement or alternative control for this pest, is needed for the production...
