Row spacing plant population weed density weed biomass maize yield
2011/1/10
A study was conducted to determine the effects of inter-row spacing (45 and 90 cm) and plant population (40000 and 60000 plants ha-1) on weed biomass and the yield of both green and grain materials of...
Nitrogen Uptake by Cover Crops and Inorganic Nitrogen Dynamics in Andisol Paddy Rice Field
Cover crop Paddy field Nitrogen
2010/12/2
Paddy field rice can conserve N in the soil under flooded conditions. However, residual soil N represents a potential environment concern when fields are no longer flooded. Winter annual grass cover c...

Dry matter Expert system Knowledge-based model LAI Rice Stem number
2009/7/24
Quantifying growth dynamics in rice (Oryza sativa L.) is important for precision design and diagnosis in cultural management. The primary objective of this study was to develop a general knowledge-bas...
Growth and Nutrient Dynamics of Buckwheat (Fagopyrum esculentum Moench) as Influenced by Different Applications of Green Soybean Manure and Bio-decomposer
Green manure growth stages Nutrient elements Relative growth rate Relative uptake rate
2009/7/23
The growth and relative uptake of N. P, K, Ca and Mg of buckwheat was measured following the application of green manure from four growth stages of soybean with and without a bio-decomposer. The relat...
