Forage brassicas are used as a forage in monoculture and multispecies mixtures, yet research defining best management practices is limited. Two studies were conducted to evaluate the effects of land preparation method planting date on establishment, mass, quality two Brassica species, ‘Inspiration’ canola (Brassica napus L.) ‘T-Raptor’ hybrid turnip (B. rapa subsp. × B. L.). Each experiment was...

A number of economic and environmental benefits are associated with the use of no-till in production agriculture in the United States. There are lower labor, energy, and machinery costs associated with no-till farming relative to conventional tillage systems and other types of conservation tillage. Reduced erosion and runoff associated with no-till also lead to a number of environmental benefit...

Data from runoff plots operated over a ®ve year period show that signi®cantly less overland ̄ow is generated with a seasonal no-till ridge system than with contour tillage or straight tillage systems. Seasonal no-till ridge is the optimum system for increasing the availability of water for rainfed agriculture on the dryland soils in the hilly area of Sichuan Province, China. # 2000 Published by...

The rice-ratoon system has long been considered an important economic, time-saving, and labor-saving planting method. Optimal tillage straw management are beneficial to increasing the growth yield of recycled rice. However, there is little research on physical chemical properties soil under management, its effects fertilizer utilization A field experiment was conducted study four types rice in ...

in a greenhouse experiment, the effects of glomus intraradices and indigenous mycorrhizal isolates from soils under plow and no-till treatments on the uptake of 32p placed at 1, 2.5 and 4 cm from the roots of white clover (trifolium repens) in 23, 37 or 46 days after planting were compared.spores of the indigenous fungi were mostly a mixture of glomus mossea, g. clarum, g. caledonium and g....

The successful commercialization of bioenergy grasses as lignocellulosic feedstocks requires that they be produced, processed, and transported efficiently. Intensive breeding for higher yields in food crops has resulted in varieties that perform optimally under high-density planting but often with high input costs. This is particularly true of maize, where most yield gains in the past have come...

Four million hectares of wheat are planted after cotton and rice in Pakistan. Little research has been done on the aronomy of wheat following these crops on a cropping pattern basis. Both of these crops delay wheat planting, and it is estimated that 40–50 kg of wheat grain is lost for every day that planting is delayed past 20 November. Current recommendations for land preparation, fertilizer u...

Introduction No other European gull has shown such a dramatic and rapid change of distribution in the last decades as the Mediterranean Gull Larus melanocephalus. Whereas in the 1940s breeding locations were restricted to coastal areas of the Black Sea in the Ukraine, Mediterranean Gulls can now be found nesting in many places scattered over Europe, in locations as near to Scotland as the Nethe...

Delserone, L. M., and Cole, H., Jr. 1987. Effects of planting date on development of net blotch epidemics in winter barley in Pennsylvania. Plant Disease 71: 438-441. The influence of planting date on fall and spring net blotch epidemics (caused by Pyrenophora teres) was evaluated with the winter barley cultivar Pennrad. Experiments were conducted in Centre County, Pennsylvania, in 1982 and 198...
