drought stress is the most important environmental constraint contributing to grain yield instability of maize(zea mays l.). evaluation of maize genotypes under different stresses would be useful for identifying genotypes that combine stability with high yield potential for stress-prone areas. this study was conducted to estimate grain yield stability of maize hybrids and to identify hybrids th...

this research covered three villages in kura local government area of kano state. the study described the socio-economic characteristics of maize producers and their production techniques and also determined the profitability and resource use efficiency in the maize production. structured questionnaires were used for primary data collection and 40 small scale producers were purposively selected...

The present study has made an attempt to discuss the effects of exchange rate volatility and price expectation on maize imports in Iran from 1980 to 2013. In doing so, using the EGARCH technique for time series econometrics, price volatility variables for both exchange rate and final price have been calculated, and the time series for these variables have been extracted. Additionally, in regard...

genetically modified (gm) foods hold the key to ending hunger and malnutrition in africa.   due to the increasing number of gmos cultivation and delay in the approval of biosafety law in nigeria, it has become necessary to screen maize products in order to determine the identity of the consumed daily foodstuffs. in this study, dna extraction from raw and processed maize foods sold commercially ...

1.はじめに CGで現実感のある画像を生成する技術は、いかにして物体を 忠実に表現するかの技術である。物体を特徴付ける要素として は、大きく分けて、物体の形状と、物体表面の色情報や光学属 性などの表面属性がある。物体の表面属性を表現する場合、一 般的には、バンプマッピングなどのさまざまなマッピング手法 がとられている。CGデザイナがマッピングに利用できる素材と しては、市販の CD-ROM やインターネット経由で入手できる素 材集、およびテクスチャ生成のプログラムから出力されるデー タなどがある。 本報告で取り扱う石畳を表現する場合、CGデザイナが路面の 敷石を1つ1つモデリングして表現することが理想ではある が、大変な労力を要するため現実的ではない。一方、石畳の写 真素材を路面にマッピングして表現することも可能であるが、 以下のような問題が生ずる。 ・テクスチャ全体として凹凸が激し...

The hfarerirds Science Cimrion Index w on CD-ROM, a new specialty index launched by the Institute for Scientific Information’@, is discussed. The index contains searchable author abstracts,

intercropping systems compared to monoculture systems can more efficiently use the existing resources which ultimately will lead to increased plant performance. therefore, to evaluate the benefits of intercropping maize and beans and assess its impact on yield and yield’s component, an experiment was conducted in factorial design with randomized complete block design in three replication, in 20...

The aim of this study was to assess the effects of strip cropping and different weed control methods on the yield and yield structure of dent maize, narrow-leafed lupin and spring oat. A split-plot design with four replications was conducted in 2008-2010. The following factors were analysed in the experiment: I. Cultivation method – sole cropping and strip cropping; II. Weed control method ...
