As salinity stress increases, yield decreases in inverse proportion. In many cases, if salinity is severe, the plant can die before they fruit or produce grains, or the yield is so less that it is uneconomical. ...
Reduced N inputs can lessen this impact (as can stubble removal) but also decreases yield. At Wagga, the application of lime in combination with phosphorous (P) increased grain yields by almost 100%, whilst stocking rates increased by 25% after six years. ...
Disc granulator(Pan granulator） The granulation disc angle of the machine is designed with a whole arc, the grain yield can reach more than 92%, At the bottom of the granulation disk, we use a number of radiation steel plate to strengthen, so our machine will be durable and never deformation. ...
Pig manure contains plentiful essential nutrition ingredients like nitrogen, phosphorus and potassium for plant growth, which can promote healthy growth and increase the yield of grain crop. Even though pig manure is a commendable raw material of organic fertilizer, lots of pig manures carry E.coli, salmonella, parasitic worms and a host of other organisms, so it ...
This harvest growers will spend significant time and money chasing down accurate yield data from combine yield monitors, grain carts and/or truck scale tickets. ...
Res. 12(3), 46-51, March 2018. To investigate the maize yield and nutrient concentration in its leaves as affected by biochar from different organic materials (wheat straw and sugarcane bagasse), a field experiment was conducted on maize crop during 2013 at koont research farm chakwal. ...
Uncertainties caused by climate change and population explosion require suitable methods for estimating grain yield during the growing seasons. This paper evaluates the applicability of the AquaCrop model in the region of western Kenya. ...
In the extremely rainy 2010, the highest yield of maize grain was obtained in rainfed plots (control = 9.24 t ha−1). ...
In the late 1900s, as per-acre grain yields moved to 3 metric tons per hectare in South and Southeast Asia and Latin America, 5 metric tons per hectare in China, and 10 metric tons per hectare in North America, Europe and Japan, there’s one place where production stagnated big time: sub-Saharan Africa, where loss of soil fertility on small farms trapped ...

The objectives of the current study were to 1) determine the best tillage practice (conventional versus conservation tillage) in terms of grain yields and potential environmental risk, 2) assess insecticidal exposure using concentrations measured in soil and runoff water and sediments, 3) compare measured insecticidal concentrations to predicted concentrations ...
As part of a cooperative of 46 farmers with approximately 1400 hectares, Kläber is applying both brains and skills to make sure they do their utmost to increase their yields of grain, maize and rapeseed. In the past decade, however, another factor has become crucial to the way they operate: environmental impact. ...
Significant ( p ≤ 0.05) differences in weeds management were observed under the tested rate of Roundup Turbo compared to un-weeded control plots. The average grain yield from conventionally tilled plots was 3.6 t ha –1 . This did not differ significantly from those of herbicide-managed plots. Low-grain yield (0.1 t ha –1 ) ...
When meat consumption falls in the United States, as it recently has, this frees up grain for direct consumption. Moving down the food chain also lessens pressure on the earth’s land and water resources. ...
Among other things, Beijing adopted a policy of grain self-sufficiency, an initiative that is now faltering. Since 2006, China’s grain use has been climbing by 17 million tons per year. ...
Instead, says Snapp, they prioritise monoculture systems aiming to maximise cereal yields, and lead to diets lacking a variety of proteins and micronutrients. ...
Multi-year field experimental data from 2004 and 2011 were used to calibrate and validate the model for simulating biomass, canopy cover (CC), soil water content, and grain yield under rainfed conditions. The model performance was evaluated using root mean square error (RMSE) and Willmott index of agreement (d) as criteria. The RMSE ranged from 0.16 to 0.38 t/ha ...
The first country to achieve a steady, sustained rise in grain yields was Japan, where the yield takeoff began in the 1880s. But for a half-century or so, it was virtually alone. Not until the mid-twentieth century did the United States and Western Europe launch a steady rise in grain yields. Shortly thereafter ...
Yet Sub-Saharan Africa has the world’s lowest grain yields and extensive areas of degraded soils. One way to help meet the food challenge would be to hold down population growth. ...
The excess production capacity was used to maintain stability in world grain markets. The large stocks of grain cushioned world crop shortfalls. ...
This rise in the demand for soybeans reflected the discovery by animal nutritionists that combining 1 part soybean meal with 4 parts grain, usually corn, in feed rations would sharply boost the efficiency with which livestock and poultry converted grain into animal protein. ...
