Quality levels of organic coffee seedlings in black and white nonwoven fabric (NWF) containers of various sizes

The introduction of organic production in coffee growing has demanded an increase for information on seedling production with standard of quality. Hence, the purpose of the present work was to evaluate how the amount of organic substrate in black and white nonwoven fabric (NWF) bags in four different sizes influences the quality index of Coffea arabica L. seedling produced in an organic system. The quality parameters...

Response of soil-surface dwelling invertebrates to alien invasive and indigenous plant cover in a sub-tropical Nature Reserve, Eastern Cape, South Africa

The soil-surface dwelling invertebrate assemblage of four sites (habitat patches) in Luchaba Nature Reserve was assessed using pitfall traps. A total of 335 specimens in three phyla (Arthropoda, Annelida and Mollusca) were sampled. Of the nine arthropod orders recorded, four were identified to seven families and ten species while five orders and two phyla (Annelida and Mollusca) were separated into 15 morphospecies. The...

Spatial variation of quality traits in Algerian durum wheat cultivated in different environments

Wheat covers more than 2.5 million hectares in Algeria and is the main staple food crop and income generation for resources-limited farmers. Area cropped in wheat is expanding however, the quality is not well known and varies from region to region. Improvement of durum wheat quality is a major concern in Algeria to better cope with the consumers’ needs. Local landraces are highly appreciated for local bread and...

Soil and water loss in Ultisol of the Cerrado-Pantanal Ecotone under different management systems

Soil and water losses were evaluated in dystrophic ultisol of the Cerrado-Pantanal Ecotone cropped with common bean, Phaseolus vulgaris L, under different tillage systems. The treatments studied were conventional tillage with primary and double secondary disking (CT), minimum tillage with chisel plow (MT) and no-tillage (NT) systems, the last associated to 4 crop densities: 0, 3, 6 and 9 Mg ha-1. In order to...

Biomass yield and partitioning of greenhouse-grown wild watermelon Cucumis africanus in response to different irrigation intervals and NPK fertilizer levels

A study was conducted during the 2009-2010 summer growing season to determine the effects of varying irrigation frequencies and NPK application rate on biomass yield and partitioning to fractions of Cucumis africanus. The experiment was laid out in a split-plot design arrangement and replicated three times. Three irrigation frequencies, namely, 2, 4 and 6 days interval, were the main plots and sub-plot treatments were...

Response of vegetative yield characters and yield of biomass fractions of wild-watermelon Cucumis africanus to irrigation interval and NPK fertilizer

Wild-watermelon, Cucumis africanus, is among important indigenous crop plants in rural Limpopo Province of South Africa, primarily used as an ethno-botanical crop and a leafy green vegetable. An experiment laid out in a split-plot design and replicated five times was conducted at the Horticultural Research Unit, University of Limpopo, South Africa. The objective was to study the effects of irrigation frequency (2, 4 and...

Population, production and improvement of local fowl of southern Nigeria ecotype

There is paucity of data on local fowls’ production in Southern Nigeria. The population and identity of the farmers involved in raising the fowl is lacking. Studies were carried out in the areas that covered Anambra, Oyo and Imo States to ascertain the population, production and improvement of the local fowl.  In six hundred households in Anambra State the population of local birds was 4,971. These consisted...

Farmers' climate change adaptation options and their determinants in Tigray Region, Northern Ethiopia

Exploring micro-level evidences is critical to fine tune effective adaptation options to cope with the adverse impact of climate change. In this regard, detailed studies on climate change adaptation options are not available in the study areas. Hence, the objective of this study was to assess farmers’ climate change adaptation options and determinant factors that influence their choice. Data were collected from...

Chemical constituents of chichá (Sterculia striata St. Hil. et Naud.) seeds

The proximate and mineral composition of chichá seeds was evaluated, as well as protein digestibility, bioactive compounds (phenols and flavonoids) and profiles of organic and fatty acids, in order to provide information to support the dietary use of this seed, adding value to the fruit and contributing to the preservation of the Brazilian Cerrado. Chichá (Sterculia striata St. Hil. et Naud.) fruits were...

Breeding and biotechnological opportunities in saffron crop improvement

Saffron (Crocus sativus L.) being triploid in nature is propagated by vegetative means through corms. The natural propagation rate of such plant species is relatively low, therefore some breeding and biotechnological technique like introduction, clonal selection, mutagenesis, micro-propagation and molecular markers have been used earlier as an alternative method of propagation for saffron. The creation of a germplasm...

Emission of CO2 and soil microbial activity in sugarcane management systems

Because of the great importance of sugarcane in the Brazilian agricultural sector, this study was developed in order to evaluate the soil CO2 flux and the soil microbial activity in the systems of burned sugarcane and green sugarcane. For this end, three areas were evaluated with different histories of sugarcane management: (1) burned sugarcane BS); (2) green sugarcane for 5 years (GS-5); (3) green sugarcane for 10...

Allelopathy in weed management: A critical review

Allelopathy is defined as both beneficial and deleterious biochemical interaction between plant and weeds, and / or plants and microorganisms through the production of chemical compounds that escape into the environment and subsequently influence the growth and development of neighboring plants. Allelochemicals are present in all types of tissues and are released into the rhizosphere by a variety of mechanism, including...
