The most cultivated crop in the Netherlands: Onion
Did you know that onions are the most cultivated crop in The Netherlands? and that it is the most widely cultivated species of the genus Allium worldwide? This crop is an herbaceous bulbous plant that is cultivated for bulb production either as biannual or perennial, depending on the cultivation conditions. Onions are among the most widely adapted vegetable crops that can be grown under a wide ...

Advantages of heating mats in seed germination
Advantages of heating mats in seed germination Germinator and heated seedbed. Is seed germination uneven and inconstant? Every time you try to germinate seeds then the seedlings do not germinate or eventually dry up. You should know that not everyone has a green thumb or the right equipment. So what do you do? You give up, just like any inexperienced and hopeless gardener would. But it’s ...

cheap 50 72 128cell trays wholesale supplier
Due to the need for higher temperature, it is necessary to sprinkle some warm water on the leaves regularly. Plants placed in a dry environment can put a layer of wet small gravel in the flower pot to promote the growth of plants. Seedlings are planted from March to April in spring, or preferably from September to October in winter. Sowing before the frost season. In winter, please manage ...

Method of composting chicken manure for garden
Chicken manure, duck manure, cattle manure and other animal manure can be recycled through composting, and then made into organic fertilizer for use in the garden. Chicken manure compost is not only environmental protection, to solve the problem of pollution, but also conducive to the growth of garden plants. Different from the fertilizer products made by professional organic fertilizer ...

How LED and HPS Lighting affects air and leaf temperature
How LED and HPS Lighting can affect air and leaf temperature: The Effects of Convective Heat vs. Radiant Heat As growers are educating themselves more on different lighting technologies, we have been faced with questions many times over about what effects different light sources have on temperature and crop production; what is the difference between Convection Heat and Radiant Heat? Anyone ...

AminoA+ Update and Autumn Recommendations 2016
AminoA+ Update With harvest 2016 coming to a close and also the first year of our commercial sales of AminoA+ we thought we should review the results and also make some recommendations based on this years’ experience. Yields OSR and Winter Barley yields were reportedly generally 30% down on 2015 levels this is undoubtedly a results of lack of sunlight in the early summer. (Two ...

Effect of the salinity stress and arbuscular mycorhizal fungi (AMF) on the growth and nutrition of the Marigold (Calendula officinalis)
In order to evaluate the effect of the Arbuscular mycorhizal fungi (AMF) on Calendula officinalis, an experimental has been carried out in term of salinity stress in totally randomized Factorials in shahrood. The samples were cultivated in tested sandy loam soil. This experiment were conducted in hub seedling (pot) method with four salinity treatment in 1.5-3.5-5.5-7.5 (dSm-1) concentration, two ...

Evaluating exposure and potential effects on honeybee brood (Apis mellifera) development using glyphosate as an example
This study aimed to develop an approach to evaluate potential effects of plant protection products on honeybee brood with colonies at realistic worst‐case exposure rates. The approach comprised two stages. In the first stage, honeybee colonies were exposed to a commercial formulation of glyphosate applied to flowering Phacelia tanacetifolia with glyphosate residues quantified in relevant ...

SOYPOD: a model of fruit set in soybean
The soybean [Glycine max (L.) Merr.] plant matches its reproductive potential to environmental conditions by adjusting the number of fruits and seeds that it produces. This adjustment is an important, but not well understood, part of the yield production process. Developing a model of fruit set will contribute greatly to a better understanding of the determination of fruit number and yield. The ...

Pollinator effects on genotypically distinct soybean cytoplasmic male sterile lines
Poor seed-set limits potential for soybean hybrid seed production. The objective of this study was to evaluate effects of different pollinators on the rate of seed set in three soybean cytoplasmic male sterile (CMS) lines, JLCMS9A, JLCMS82A, and JLCMS89A. The following five treatments were applied under net room isolation-conditions: (i) insecticide application and release of alfalfa leafcutter ...

Efficacy of herbicide seed treatments for controlling striga infestation of sorghum
Witchweed (Striga spp.) infestations are the greatest obstacle to sorghum [Sorghum bicolor (L.) Moench] grain production in many areas in Africa. The objective of this study was to evaluate the efficacy of herbicide seed treatments for controlling Striga infestation of sorghum. Seeds of an acetolactate synthase (ALS) herbicide–tolerant sorghum hybrid were treated with two ALS-inhibiting ...

Sowing and flowering delays can be an efficient strategy to improve coexistence of genetically modified and conventional Maize
The coexistence between genetically modified (GM) and non-GM maize (Zea mays L.) fields is subjected to regulation in several countries. A strategy to reduce cross-pollination from GM to non-GM fields was evaluated, on the basis of reducing the flowering coincidence by sowing at separate times. The trial included narrow plots in which transgenic maize was sown before, simultaneously, and after ...

Agronomic performance of different pea cultivars under various sowing periods and contrasting soil structures
Yield variability of spring pea (Pisum sativum L.) in farmers' fields is mainly due to soil compaction at sowing and abiotic stresses during the reproductive period. Winter peas flower earlier, and thus should be less sensitive to abiotic stress at the end of the cycle, but because of their sensitivity to frost they must be sown late in autumn when soils are very wet. Pea breeders are working on ...

Model-based approach to quantify production potentials of summer maize and spring maize in the north China plain
The North China Plain (NCP) belongs to the major maize (Zea mays L.) growing areas in China. Maize yields have increased steadily since the 1980s, but in recent years average yields have stabilized around 5000 kg ha–1. The objective of this study was to quantify the production potential of summer and spring maize in the NCP. For this purpose the CERES-Maize model was calibrated and validated. The ...

Pesticides in the European Union
There has been a sharply falling trend in the total volume of sales of agricultural pesticides in the EU between 1991 and 1995. But this was reversed in 1996. From 1991-1995, EU sales of pesticides, measured by weight of active ingredients (ai), fell by 13%. They then rose by 6% between 1995 and 1996 to stand at 299,826 tonnes ai. But this still put them nearly 8% below the 1991 figure. The use ...
