A technical package for eco-agriculture is the assembly of multiple techniques for a functional and goal-oriented agro-ecosystem management. The resources can originate from traditional agro-practices, modern agro-practices and high-tech innovations. There are inseparable, compatible, or incompatible relationships between a single technique and a specific agro-ecosystem. Also, there are mutually dependent,...

Crop row spacing in intercropping systems affects interactions of crop species and subsequent crop yields. In a field experiment, the response of crop yield to different maize row spacing (0-80 cm) in pea/maize intercropping system was investigated. The results showed that land equivalent ratio (LER) of each treatment exceeded 1,...

Cotton-based intercropping is a popular agronomic practice in Northwest China that addresses the conflict on planting area between cereals and cotton. However, not sufficient knowledge exists on the yield advantage, nutrient uptake and conversion of cotton-based intercropping. In this paper, the uptake and conversion efficiency of nitrogen (N), phosphorus (P)...
