Biodynamic agriculture

The genus Brassica is one of 51 genera in the tribe Brassiceae belonging to thecrucifer family, and is the economically most important genus within this tribe,containing 37 different species. Many crop species areincluded in the Brassica genus, which provide edible roots, leaves, stems, buds,flowers and seedCrops.Crops belonging to this genus are occasionally called Cole crops—derived from the Latin caulis, denoting the stem or branch of a plant.[1] Members of Brassica commonly used for food…

More climate events may endorse plant disease and pest outbreaks (Gan, 2004). The flood’s destruction in South Asia’s low-lying and urban areas is cruelly complemented by the effects that drought and variation in periodic rainfall will have on agriculture. Extreme heat is already disrupting the growing season in Pakistan, India, and Bangladesh. Wheat production in the Indian, fertile areas of Pakistan and Bangladesh, may decrease up to 50 percent by 2100, harming the millions of people who rely…

Introduction As differences in carcass quality moved the market trends towards more grid pricing, factors which are contributing to the quality of carcass is essential. These factors include genetics, gender of cattle, natural growth patterns, as well as manipulation of cattle diets in their feed. Growth Patterns The growth of carcass is made up mainly of protein and fat. As cattle is approaching mature weight, the gain of carcass makes up a higher percentage of the total gain. This makes the…

Similarity indices and genetic distance The overall mean similarity index for Brassica oleracea accessions calculated based on all AFLP fragments amplified using Nei’s (1978) similarity index, ranged from 0.297 to 0.999 with an average of 0.744 (Table 3). The highest similarity indices (0.999) and the lowest genetic distance (0.001) were between the accessions of the same crop variety and geographical region, e.g. spring cabbage HRIGRU4564 and HRIGRU4571 from Cork. Accessions having close…

Rotavator Saeed Firouzi and Mohammadreza Alizadeh (2012) [1]: has performed field experiment to evaluate different weeding method for groundnut. The weeding method included two power tiller operated weeders Cultivator and Rotavator. Study was carried out at three different forward speeds of 1, 1.5 and 2km/hr. For all the factors Rotavator gave superior results than Cultivator. The maximum soil manipulation was achieved by Rotavator at lowest forward speed of 1km/hr. which leads to higher crop…

The agronomic production function approach begins with the primary correlation between climate and crop production. Via studies, agronomists have adjusted models which forecast the produce of specific crops determined by weather patterns. These imitation models have long been utilized to forecast changes in produce for specific crops. The results from these models is then integrated into an economic model of farmer behavior, which in turn leads to a partial equilibrium model of the farm sector.…

Genetically modified (GM) crops seem to be the solution to feeding billions of people, although their negative long-term impacts are still a heavily debated…

BACKGROUND Pigs have been essential to human’s life even before wild animals were domesticated. Ancestors of pigs comes from Asia and Europe 25 million years ago, however its domestication pigs began 6000 to 8000 BC. Pigs were highly produced in Asia especially China which is the highest pig producer even currently. Pigs arrived in South Africa in in 1600’s with the European settlers. South Africa’s indigenous breeds are the Windsnyer (Ramsay, 2002). Breeds which are also found and commercially…

The fungi Alternaria is a phyto-pathogen cause leaf blight disease to variety of plants. Alternaria alternata and Alternaria helianthi was isolated from Dalbergia sissoo L. and Helianthus annuus L. respectively. Test antagonists grow faster than the pathogen and produced inhibition zones thereby limiting the growth of the pathogen. These antagonistic interactions influence the incidence and severity of the disease caused by the pathogen. When the two Alternaria spp. were tested by dual culture…
