On-farm demonstration trials have been used for many years to introduce new techniques and management practices to farmers. With new precision agriculture technology, it is now possible to work more effectively using whole fields instead of small test plots. Sugarbeet (Beta vulgaris L.) growers in the Drayton, ND, and St. Thomas, ND, sugarbeet cooperative districts have delivered sugarbeet hist...

Basically all organisms can be classified as determinate growers if their growth stops or almost stops at maturation, or indeterminate growers if growth is still intense after maturation. Adult size for determinate growers is relatively well defined, whereas in indeterminate growers usually two measures are used: size at maturation and asymptotic size. The latter term is in fact not a direct me...

We analyze the contract settlement data of a poultry company who contracts the production of broiler chickens with a group of independent growers. The company originally used rank-order (ordinal) tournaments to compensate their contract growers and later switched to cardinal tournaments. Based on the observed payment mechanism we construct an empirical model of a rank-order tournament game and ...

The study of poverty and income in equality are the most important subjects of social/ economic research in agriculture sector. The present study focuses on poverty and income inequality among pistachio growers in Kerman province. Absolute poverty line, relative poverty line, poverty gap and intensity were calculated. Also income distribution was investigated using Ginny coefficient, Lorenz cur...

Research Brief #15 4) This research found that growers were relatively mixed in their evaluations of the necessity of fumigants to the viability of their operations and to the viability of the strawberry industry as a whole. Some growers said that they would be unable to stay in business if fumigants were phased out, while others were nonplussed by the prospect of an eventual phase-out, arguing...

The ITGA was created with the objective of providing a collective voice for growers from all over the world. In 1999 the ITGA’s head-office moved to Castelo Branco, Portugal, where the ...

Market pressure is forcing New Zealand greenhouse tomato growers to shift from conventional to more environmentally-friendly pest control methods such as IPM (Integrated Pest Management). Growers can access IPM manuals, but these tend to provide generalized advice, which they find difficult to apply to their own situations. Alternatively, growers can use consultants to tailor IPM strategies to ...

here are about 220 types of cannabis mentioned on the websites of Canada’s 13 licensed medical marijuana growers. Several growers name their products after their companies. Others use names that resemble pharmaceutical names or allude to therapeutic benefits. Many growers, however, are using recreational names. They might want to reconsider that choice if they want the medical community to take...

A review of organic growers' concerns about weeds is presented and several issues that may ease those concerns are highlighted. The underlying principles of organic weed management (OWM) are briefly discussed and results from organic grower surveys regarding weed management practices in organic horticultural cropping are presented. The most common weeds encountered by organic growers, often tho...

Cocaine is extracted from coca: a native bush from the Amazon rainforest. Coca is mostly grown in remote areas to avoid government intervention, and it has been increasingly cultivated inside protected areas (PAs). The effects of coca cultivation on the preservation of PAs are largely unknown. This research uses panel data (2006–2008) from a total of 684 farmers to evaluate the influence of coc...
