Variation in Yield Gap Induced by Nitrogen, Phosphorus and Potassium Fertilizer in North China Plain
A field experiment was conducted under a wheat-maize rotation system from 1990 to 2006 in North China Plain (NCP) to determine the effects of N, P and K on yield and yield gap. There were five treatments: NPK, PK, NK, NP and a control. Average wheat and maize yields were the highest in the NPK treatment, followed by those in the NP plots among all treatments. For wheat and maize yield, a signif...
Results We present global planting date patterns for maize, spring wheat and winter wheat (our full, publicly available data set contains planting and harvesting dates for 19 major crops). Maize planting in the northern mid-latitudes generally occurs in April and May. Daily average air temperatures are usually c. 12–17 °C at the time of maize planting in these regions, although soil moisture of...
Mixed cropping is practised widely in developing countries and is gaining increasing interest for sustainable agriculture in developed countries. Plants in intercrops grow differently from plants in single crops, due to interspecific plant interactions, but adaptive plant morphological responses to competition in mixed stands have not been studied in detail. Here the maize (Zea mays) response t...
A field experiment was conducted to observe the influence of a cover crop (winter wheat, Triticum aestivum L.), and a perennial weed (dandelion, Taraxacum officinale Weber ex Wigg.), on vesicular-arbuscular mycorrhiza (VAM) inoculum potential, soil aggregation, and maize yield after one season. Mycorrhizal colonization of maize roots was higher following the autumn planting of either winter whe...
Two origin of starch – maize and wheat were tested by using four non lactating cows with rumen and duodenal Tcannules in the experiment. Cr2O3 was used as a marker of nutrient flow to the duodenum. Cows were fed diets consisting of, %: forage 70, maize and/or wheat meal 27 and/or 29, soyabeanmeal 2 and vitamix S 1, on dry matter basis. Starch origin did not affect ruminal fermentation significa...
Maize and wheat are main field crops on arable lands in Croatia. According to the data of the State Bureau for Statistics (Statistical Yearbook 2011) in the five-year period (2006-2010) mean used agricultural land in the category arable land and gardens in Croatia was 867123 ha. Mean harvested areas of maize (298412 ha) and wheat (176794 ha) occupied 55% of used arable land of the country. Majo...
Inflorescences of the tribe Triticeae, which includes wheat (Triticum sp. L.) and barley (Hordeum vulgare L.) are characterized by sessile spikelets directly borne on the main axis, thus forming a branchless spike. 'Compositum-Barley' and tetraploid 'Miracle-Wheat' (T. turgidum convar. compositum (L.f.) Filat.) display noncanonical spike-branching in which spikelets are replaced by lateral bran...
Wang Shengfeng,Xu Jianxin,Yang Shuqin,Jia ping (North China University of Water Resources and Electric Power, Zhenzhou, P. R. China) Email:[email protected] Abstract:Winter wheat and summer maize were important grain crops in China,and winter wheat-summer maize continuous cropping was the main tillage method in north China.According to field experiment datas, Jensen models of winter wheat and...
BACKGROUND Lower Saxony (Germany) has the highest installed electric capacity from biogas in Germany. Most of this electricity is generated with maize. Reasons for this are the high yields and the economic incentive. In parts of Lower Saxony, an expansion of maize cultivation has led to ecological problems and a negative image of bioenergy as such. Winter triticale and cup plant have both shown...
Comparison of the genetic map of maize chromosome 9 with maps of wheat chromosomes has revealed a high degree of colinearity between maize chromosome 9 and the group 4 and 7 chromosomes of wheat. The order of DNA markers on the short arm and a proximal region of the long arm of the genetic map of maize chromosome 9 is highly conserved with the marker order on the short arm and proximal region o...
