In order to evaluate the yield, yield components and protein contents of two wheat cultivars (Zarrin and Gaspard) in sole cropping and intercropping systems,an experiment was conducted using replacement serious technique and different combinations of intercropping with high plant density and optimal of each cultivar. A factorial experiment was conducted in the form of randomized complete block ...

Conventional field cropping systems have been criticized as being unsustainable because they contribute to on-farm and off-farm environmental degradation, and are often economically uncertain. Methods to increase environmental and economic sustainability are needed. There is a critical need to develop management technologies to maximize yield and crop quality yet improve environmental impacts o...

Arbuscular mycorrhizae (AM) fungi play a crucial role in the growth of soybean; however, the planting system employed is thought to have an effect on AM fungal communities in the rhizosphere. This study was performed to explore the influence of continuous soybean cropping on the diversity of Arbuscular mycorrhizal (AM) fungi, and to identify the dominant AM fungus during the seedling stage. Thr...

The bioavailability and fractionation of Cu reflect its deliverability in soil. Little research has investigated Cu supply to crops in soil under long-term rotation and fertilisation on the Loess Plateau. A field experiment was conducted in randomized complete block design to determine the bioavailability and distribution of Cu fractions in a Heilu soil (Calcaric Regosol) after 18 years of rota...

Mixed cropping (including agroforestry) often gives yield advantages as opposed to monocropping. Many criteria have been used to assess yield advantage in crop mixtures. Some of these are presented. In addition, the relative merits of replacement, additive and bivariate factorial designs are discussed. The concepts of analysis of mixed cropping are applied to an example of an alley cropping (a ...

Europe's agriculture is highly specialized, dependent on external inputs and responsible for negative environmental impacts. Legume crops are grown on less than 2% of the arable land and more than 70% of the demand for protein feed supplement is imported from overseas. The integration of legumes into cropping systems has the potential to contribute to the transition to a more resource-efficient...

Most digital watermarking techniques are susceptible to damage by data cropping. Although the effects of cropping might not be perceptible, watermark recovery may be rendered difficult or impossible due to the desynchronization of the recovery process. The transform encryption coding (TEC) based watermarking algorithm was presented at ICASSP 2000 [2]. The present paper investigates the performa...

In agrarian developing countries the natural environment is a key determinant of both poverty and nutritional status. Climate, terrain, and soil characteristics drive the agricultural system, determining in large part cropping patterns, choice of crops, yield rates, and overall productivity levels. The human resources crucial to agricultural productivity are also influenced by the natural envir...

We propose a cell progeny tracking method that sequentially employs image alignment, chamber cropping, cell segmentation, per-cell feature measurement, and progeny (lineage) tracking modules. It enables biologists to keep track of phenotypic patterns not only over time but also over multiple generations. Yeast cells encapsulated in chambers of a polydimethylsiloxane (PDMS) microfluidic device w...
