Effects of Application of Zn,Fe,and Mo on the Alfalfa Yield and Their Contents and Absorption Amounts;

Study on the Effect of Different Application Rate of Beef Cattle Feces on Yields and Nutrients Level of Dwarf Elephant Grass and on the Degradation Rate of Dry Matter;

Effect of seeding-year clipping frequency on root weight and yield in alfalfa and brome grass mixture swards;

Studies on grass yield monitoring and predicting models of natural grassland using remote sensing data in Northern Xinjiang.;

The grass yield was 22 000 kg/hm2 in the second year and 38 000 kg/hm2 in the third year The proper harvest time was before the flowering stage.

Sowing period distinctly affected the grass yield and gross protein yield.

Regression analysis between forage yield and quality traits in sorghum-sudangrass hybrid;

Effect of foliage dressing on forage yield and nutrition value of alpine grassland;

Field caging and simulated feeding were conducted to study the effects of grasshoppers of different development periods and densities on forage yield on grasslands,using the 1~(st)-3~(rd),4~(th) and 5~(th) instars and adults of Oedaleus asiaticus B.

The different sowing periods obviously shown the effect on the hay yield and the production performance such as the dry-fresh ratio and the leaf-stem ratio.

A randomized block design was adopted to study growing characteristics,winter-survival rate and hay yield of alfalfa sown in dryland-farming regions of southern Ningxia province on different dates.

By doing field fertilizer experiment with three factors three levels orthogonal experiment design of alfalfa, the objective of this study showed that the effects of applied nitrogen, phosphorus, potassium ratio fertilizer on alfalfa hay yields, nutrient absorption and soil fertility in the first year and the following year.
