Minor cereals such as barley and small millets contributed 1.13–1.73 1.95–2.78% to the total production acreage, respectively, during 2010–11 2020–21. The present study analyses trends in area, yield (2010–11 2020–21); breeding varieties seed chain of minor 2021–22. Barley acreage ranged between 7.0 lakh ha (2010–11, 2012–13) 5.9 (2019–20), registering a decline 18.6%. Production showed an incr...

in this study, total factor productivity(tfp) growth of sugar beet in iran during 1989-1990 through 2007-2008 was analyzed, using nonparametric malmquist approach. so, amounts of inputs usage including seeds, fertilizers, insecticides, herbicides, labor, water use and acreage in one hand and output of sugar beet production on the hand were taken into account. results showed that sugar beet prod...

The number of transgenic cotton cultivars available for commercial production has increased greatly in recent years. Cotton producers now have multiple choices when choosing transgenic cotton cultivars. The choice of cultivar now dictates the insect and weed control programs that will or can be used. It is estimated that, in 2003, at least 77% of Arkansas’ cotton acreage was planted to a stacke...

of public lands as wilderness continues to be a contentious issue. With about 45 million acres designated as wilderness in the lower 48 states, the question of whether designation of additional wilderness would result in increased recreation use has been raised. We address this issue using a jxed-effects regression model for wilderness use at national forests and national parks throughout the U...

Organic farming has grown rapidly in the Pacific Northwest (Oregon, Idaho, and Washington) during the past decade. Certified organic acreage in Washington alone increased eight-fold between 1993 and 2002. Yet the 145,000 certified acres in the three states still comprise less than 1% of the total farmland base. With the growth of the organic sector has come a commensurate expansion of research,...
