Fungal Colonization of Alfalfa Stubble Following Harvest

Nitrogen Fertilization of Wheat No-Till Planted in Alfalfa Stubble

The N available after legumes is sufficient for maximum crop yields in many cropping systems. Fertilizing without accounting for the "extra" N mineralized from legume residues can contribute to high nitrate-N concentrations in the soil during crop production and increase nitrate-N leaching potential. Tillage practices also affect the physical, biological, and chemical nature of the soil, changi...

Lupin Grain as a Supplement to Sheep Grazing Cereal Stubble

Two experiments tested the use of lupin grain as a supplement for weaners grazing wheat stubble. The control groups in both trials received no supplement until liveweights dropped to 22 kg and then lupins were fed. In 1984 two lick-blocks were tested; the Rumevite "Sheep and Cattle" block and the ICI "Ultrapro 30" block. Liveweight changes of animals on the control (5 weeks), Rumevite block, IC...

Grain-filling Pattern of Super Hybrid Rice Liangyoupeijiu under Direct Seeding and Transplanting Condition

To evaluate the grain-filling pattern, Chinese first super hybrid rice, Liangyoupeijiu was grown under tillage and establishment methods at a spacing of 20 cm × 20 cm with one seedling hill-1 and at a seeding rate of 22.5 kg ha-1 in Changsha, Hunan Province, China in 2012. Our results showed that, superior grain weight in TP had always higher than DS up to 24 DAH but at 36 DAH, grain weight had...
