The present study was conducted to measure the flow of microbial and nonmicrobial N fractions entering the omasal canal of lactating dairy cows fed grass-red clover silage supplemented with barley and rapeseed meal. Four ruminally cannulated Finnish Ayrshire dairy cows were fed, in a 4 x 4 Latin square design, grass-red clover silage alone or supplemented with (on DM basis) 5.1 kg/d of barley, ...

the effects of inoculation of thiobacillus and the type of nitrogen fertilization (urea and ammonium sulphate fertilizers) on yield and yield components of rapeseed cultivars (okapi, slm 046 and reagent * cobra) were studied. the experiment was carried out as spilit plot factorial in randomized complete block design with 4 replications in shahrood university of technology. reagent * cobra culti...

scarcity of irrigation water and decreasing of water resources with suitable quality are the most important limiting factors in the crop production in the most of countries such as iran . therefore research for optimum usage of water and economy in consume water is important policies for growing of production and  the selection of cultivars with less necessity of water can help to matter.so, an...

Pre-harvest desiccation of rapeseed crop may allow a more timely harvest as well as increase the speed and harvest operation efficiency as a second crop after rice. An effective desiccant which could be used as a harvest-aid with no negative effects on rapeseed yield and quality would be advantageous for oil seed crop producers and may reduce yield losses with no interferential effects on rice ...

Cotton-rapeseed or cotton-wheat double cropping systems are popular in the Yangtze River Valley and Yellow River Valley of China. Due to the competition of temperature and light resources during the growing season of double cropping system, cotton is generally late-germinating and late-maturing and has to suffer from the coupling of declining temperature and low light especially in the late gro...
