The Marquillo x Kenya Farmer 1 "grass-clump" dwarf selection of Triticum aestivum L. was grown under continuous 2000 foot candle light and several regimes of alternating 16 degrees and 26 degrees temperatures combined in total cycle lengths of 6, 12, 24, or 48 hr. Plants at 26 degrees grew as normal wheat. Those exposed to 0.25 to 2 hr of 16 degrees per cycle showed typical "grass-clump" dwarf ...

P Cotton, by Nellie Mae Rowe (1900–1982), is a work of folk art that captures Rowe’s experiences as an African American woman living in rural Georgia, United States. Nellie Mae Rowe was born on July 4, 1900, as the ninth of ten children. The family lived on a rented farm 20 miles south of Atlanta. Her father, a farmer and blacksmith, was born a slave in 1854; her mother, born the year after Pre...

Reducing tillage intensity offers the possibility of moving towards sustainable intensification objectives. Reduced tillage (RT) practices, where the plough is not used, can provide a number of environmental and financial benefits, particularly for soil erosion control. Based on 2010 harvest year data from the nationally stratified Farm Business Survey and drawing on a sub-sample of 249 English...

This study offers evidence of the robustness of farmer rice varieties (Oryza glaberrima and O. sativa) in West Africa. Our experiments in five West African countries showed that farmer varieties were tolerant of sub-optimal conditions, but employed a range of strategies to cope with stress. Varieties belonging to the species Oryza glaberrima - solely the product of farmer agency - were the most...

The rice theory of culture is the idea that farming societies developed into more interdependent, tight cultures in response to demands plant. Farming general an interdependent subsistence style, but traditional paddy was starkly different from other major crops like wheat, corn, and potatoes. Paddy required twice as much labor per hectare wheat farming. Farmers responded by creating customs sh...

the our purpose of objective is evaluation and comparison the energy flow in wheat lands of cities in alborz province. we try to calculate the indexes of energy ratio, gross energy, specific energy, energy efficiency, energy intensity, total input and output energy. population of the study consisted of farmers of cities in alborz province in the year of 1391-92. it was a best way that we use po...

an evaluation of the relationship between crop yield and soil properties would be useful in estimating the fluctuations in yield, and in an implementation of correct field management. the study was conducted in farmer operated wheat fields in sorkhankalateh district, 25 km northeast of gorgan, golestan province, iran. soil samples (0-30 cm depth) were collected just after crop planting at the e...

Global food security requires eco-efficient agriculture to produce the required food and fiber products concomitant with ecologically efficient use of resources. This eco-efficiency concept is used to diagnose the state of agricultural production in China (irrigated wheat-maize double-cropping systems), Zimbabwe (rainfed maize systems), and Australia (rainfed wheat systems). More than 3,000 sur...

Grain harvest has to be done in a timely manner, in order to harvest the whole farm within the available suitable weather days for the operation. This short period combined with an increasing farm size, has lead farmers to buy more expensive combines with higher theoretical harvest capacity. A bigger combine does not automatically imply higher capacity. The grain harvesting process involves the...
