Soil cultivation is commonly used to manage organic matter (OM) accumulation in golf course putting greens. Our objectives were to determine: (i) if hollow-tine cultivation is more effective than solidtine cultivation at managing OM and water infiltration, (ii) if venting methods are effective at managing OM and water infiltration, and (iii) if venting alters or interacts with effects of earlyo...

Root-knot nematodes represent one of the most important plant pathogens in Pomegranate cultivation regions. By studying structure plant-parasitic community inhabiting rhizosphere fields, it was found that

Actinobacteria (actinomycetes) have been received much attention, as these bacteria pro‐ duce a variety of natural drugs and other bioactive metabolites. The distribution of acti‐ nomycetes in various natural habitats, including soil, ocean, extreme environments, plant, lichens and animals, is described. The collection and pretreatment of test samples from different sources, design principle of...

Studies on breeding Anopheles albitarsis and association with rice growth in irrigated paddy fields were carried out during the rice cultivation cycle from December 1993 to March 1994. This period corresponded to the length of time of permanent paddy flooding. Breeding occurred in the early stage up until five weeks after transplantation when rice plant height was small. That inverse correlatio...

Introduction. Erysiphe cichoracearum /Ec/ is the predominating powdery mildew species on cucurbits in the Czech Republic (5). Its occurrence and spreading on cucurbits can be influenced not only by virulence, but also by aggressiveness of isolates within natural pathogen populations. Both forms of pathogenicity have an impact on plant cultivation and protection and should be considered in resis...

“Hemp” refers primarily to Cannabis sativa L. (Cannabaceae), although the term has been applied to dozens of species representing at least 22 genera, often prominent fiber crops. For examples, Manila hemp (abaca) is Musa textilis Née, sisal hemp is Agave sisalina Perrine, and sunn hemp is Crotolaria juncea L. Especially confusing is the phrase “Indian hemp,” which has been used both for narcoti...

The difficult cultivation of the saffron plant (Crocus Sativus L.) make the spice of the same name made from its dried stigmas very valuable. It is estimated that some 75,000 blossoms or 225,000 hand-picked stigmas are required to make a single pound of saffron, which explains why it is the world's most expensive spice. The aim of this study was to identify ways of increasing the fertility and ...

The business dynamics of the agricultural sector generally call for a system of calculation and cost management that goes beyond output assessment and profit determination, and coordinates a tool that supports the decision-making process, thus facilitating the evaluation of different cultivation techniques, varieties and so on. Accordingly, this paper proposes using a cost model based on activi...

In this paper we presented a method for the preparation and characterization of glutathione-coated near infrared (NIR) QDs (CdSeTe/CdS) with core-shell structure. The preparation method is based on surface modification of hydrophobic core/shell CdSeTe/CdS by glutathione, which makes the QDs water-soluble and stabilized in aqueous solution. The particles were further added to cultivation solutio...

We report that an endophytic filamentous fungus species of the genus Diaporthe isolated from Cinchona ledgeriana (Rubiaceae) produces Cinchona alkaloids (quinine, quinidine, cinchonidine, and cinchonine) upon cultivation in a synthetic liquid medium. This study provides evidence that Cinchona alkaloids are produced not only in Cinchona plant cells, but also in the endophytic microbe cells, and ...
