A double cropping system has been commercially adopted in southern China, where there is abundant sunshine and heat resources. In this viticulture system, the first growing season normally starts as a summer cropping cycle; then, the vine is pruned and forced, resulting in a second crop in winter. Due to climate differences between the summer and winter growing seasons, grape ripening progressi...

Rainfed agriculture occupies 68% of India’s cultivated area and supports 40% of the human and 60% of the livestock population. It produces 445 of the food requirement, thus has and will continue to play a critical role in India’s food security. However, aberrant behaviour of monsoon rainfall, eroded and degraded soils with multiple nutrient and water deficiencies, declining ground water table a...

The winter wheat/summer fallow rotation is the most common cropping system in eastern Oregon. It is used to store winter precipitation and control weeds. This cropping system, however, destroys soil organic carbon, reduces water infiltration and thus leads to soil erosion, and is not sustainable. Conservation tillage, annual cropping, and the introduction of alternative crops are ways to improv...

The effects of cultivar mixture cropping on yield, biomass, and water use efficiency (WUE) in winter wheat (Triticum aestivum L.) were investigated under non-irrigation (W0, no irrigation during growth stage), one time irrigation (W1, irrigation applied at stem elongation) and two times irrigation (W2, irrigation applied at stem elongation and anthesis) conditions. Nearly 90% of cultivar mixtur...

Marton (Argillic Perched-gley Pallic, Typic Endoaqualf), Ohakune (Typic Orthic Allophanic, Typic Hapludand), and Westmere (Mottled Mafic Melanic, Mollic Hapludalf) soils with differing structural vulnerability were compared at matched sites under different land uses. Topsoil samples (0-10 cm) from indigenous forest (>50 yr), permanent pasture (>50 yr), pine plantation (>20 yr), or arable croppi...

In order to investigate the change rules and response characteristics of growth status on each component of poplar seedling followed by continuous cropping generations and growth period, we clear the biomass distribution pattern of poplar seedling, adapt continuous cropping, and provide theoretical foundation and technical reference on cultivation management of poplar seedling, the first genera...

Interest in trap cropping, a traditional tool of pest management, has increased considerably in recent years. In this review we propose a broader definition of trap cropping that encompasses the inherent characteristics of the trap crop plants themselves as well as the strategies associated with their deployment. Inherent characteristics of a trap crop may include not only natural differential ...

Rice is cultivated in the Mekong River Delta of Vietnam under various cropping systems and cultivation techniques, influenced largely by environmental conditions. This paper describes a study on the dynamic changes in rice cropping systems in response to changes in agro-hydrological conditions resulting from infrastructure interventions to prevent salinity intrusion. Multi-date cloud-penetratin...

Image cropping aims at improving the aesthetic quality of images by adjusting their composition. Most weakly supervised cropping methods (without bounding box supervision) rely on the sliding window mechanism. The sliding window mechanism requires fixed aspect ratios and limits the cropping region with arbitrary size. Moreover, the sliding window method usually produces tens of thousands of win...
