in order to evaluate radiation capture and use efficiency and productivity in sole and intercropping of three crops, rapeseed (brassica napus l.), bean (phaseolus vulgaris l.) and corn (zea mays l.), an experiment was conducted in mashhad region during the growing season of 2007-2008. in this study six treatments including three sole cropping of the crops (rapeseed sown in 22 september 2007, co...

The main drawback of the forcing vine regrowth technique is loss yield (Martínez de Toda, 2020). In order to avoid such and not eliminate primary clusters already formed on shoots, it possible force development latent buds fifth sixth nodes, while maintaining shoots. this way, forced can be added normal or article, experiments carried out Grenache, Tempranillo Maturana Tinta varieties in La Rio...

background and objectives: recently, double-cropping of rice in mazandaran due to favorable climate condition is highly interested by the rice farmers. so that, after harvesting of main crop of rice, farmers can grow again one crop of rice during summer, especially in the years which climate conditions are suitable for double cropping of rice in a rice-rice growing system. therefore, developmen...

Cereal crops especially maize production in Ethiopian Central Rift Valley is affected by biotic and abiotic production. This study was conducted for two seasons (2015-2016) the best cropping system identified using Randomized Complete Block Design with three replications. The experiment had six treatments (1) Continuous mono-cropping under conventional practice (CN), (2) continuous mono conserv...

Cropping intensity is one of the major factors in crop production and agricultural intensification. A new double-cropping croplands mapping methodology using Moderate Resolution Imaging Spectroradiometer (MODIS) time series datasets through continuous wavelet transform was proposed in this study. This methodology involved four steps. First, daily continuous MODIS Enhanced Vegetation Index (EVI)...

Residue management in cropping systems is useful to improve soil quality. However, the studies on the effects of residue management on methane (CH4) and nitrous oxide (N2O) emission from paddy field in southern China are few. Therefore, the emissions of CH4 and N2O were investigated in double cropping rice (Oryza sativa L.) systems with different winter covering crops using the static chamber-g...

Agricultural practices are continually changing at various spatial and temporal scales in response to local management decisions and environmental factors. However, few regional scale land use/land cover (LULC) classifications have focused on characterizing the agricultural sector, particularly on a regular basis to reflect croprelated land use changes that occur from year to year. More detaile...

Nonhomologous repair of double-stranded breaks, although fundamental to the maintenance of genomic integrity in all eukaryotes, has received little attention as to its evolutionary consequences in the generation and selection of phenotypic diversity. Here we document the role of illegitimate recombination in the creation of novel alleles in VRN1 orthologs selected to confer adaptation to annual...
