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...

Nitrogen-mineralization rates are needed to accurately determine N fertilization requirements to meet plant needs while minimizing environmental contamination. A spring wheat (Triticum aestivum L.)-fallow (SW-F) system was compared with a spring wheat-winter wheat-sunflower (Helianthus annuus L.) (SW-WW-SF) system on a Temvik-Wilton silt loam (finc-silty, mixed Tj pic and Pachic Haploborolls) a...

Cropping systems based on carefully designed species mixtures reveal many potential advantages in terms of enhancing crop productivity, reducing pest and diseases, and enhancing ecological services. Associating cereals and legume production either through intercropping or rotations might be a relevant strategy of producing both type of culture, while benefiting from combined nitrogen fixed by t...

Nematode-resistant tropical legumes are effective in reducing populations of plant-parasitic nematodes when used in rotation systems. Mixed cropping is a common practice of many small farmers in Central America, but little is known about the effects of tropical legumes on nematode communities under these systems. To examine the effects of intercropping on the nematode fauna associated with squa...

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...

to compare the quantity and quality of forge production in intercropping systems with maize, pinto bean and pumpkin, an experiment based on randomized complete block design with three replications was conducted at faculty of agricultural science, university of guilan, during 2012 growing season. the treatments consisted of maize, pinto bean and naked pumpkin sole cropping, maize – pinto bean an...

The effects of cropping systems (fallow, rotation with sorghum-sudangrass hybrid [Sorghum bicolor x S. sudanense], and continuous soybean [Glycine max]), nematicide (aldicarb) treatment, and soybean cultivar on yield and nematode population densities were studied in a field infested with a mixture of Meloidogyne spp. and Heterodera glycines. Soybean following sorghum-sudangrass yielded 111 kg/h...

The objective of this study was to assess the effect mix-cropping, Yangtsepa corn variety with legume Sesbania, and single cropping on forage yield quality at 60-, 90-, 120-days harvest. Randomized Complete Block Design (RCBD) three replications used as an experimental design. pea were line sown 20 cm apart a seed ratio 50:50. results showed higher (26.1 t/ha), dry matter 23.83% 120-day overall...
