Maize (Zea mays L.) is an important food security crop in Ethiopia. However, low soil fertility and the use of haphazard nitrogen (N) fertilizer with little attention to rate timing N application constrain productivity. Therefore, field experiments were conducted during 2019 2020 cropping seasons investigate response maize different rates timings. The treatments consisted six (0, 23, 46, 69, 92...

Spatial monitoring of the sowing date plays an important role in crop yield estimation at the regional scale. The feasibility of using polarimetric synthetic aperture radar (SAR) data for early season monitoring of the sowing dates of oilseed rape (Brassica napus L.) fields is explored in this paper. Polarimetric SAR responses of six parameters, relying on polarization decomposition methods, we...

Deep-sowing is an effective measure to ensure seeds absorbing water from deep soil layer and emerging normally in arid and semiarid regions. However, existing varieties demonstrate poor germination ability in deep soil layer and some key quantitative trait loci (QTL) or genes related to deep-sowing germination ability remain to be identified and analyzed. In this study, a high-resolution geneti...

The article discusses the impact of machine-tractor unit (MTU) undercarriages during soil cultivation and agricultural crops. With a movement row-crop units across field, MTU propellers repeatedly compact soil. This negatively affects production seedlings, growth development plants, yield In this regard, these studies are purposed at determining compaction effects on conducting an agroecologica...

The field research was carried out at the Látókép AGTC KIT research area of the University of Debrecen in EasternHungary, on the area of the aeolain loess of the Hajdúság. We examined the effects of the sowing time on the phytopathogenic characteristics and yield production by applying various fertilizer treatments on two different sunflower genotypes (NK Ferti, PR64H42) in 2012 and 2013. We ap...

1 We present results from a long-term sowing experiment conducted in nutrient-poor savanna grassland in eastern Minnesota. We examine the effects of a one-time seed addition of 23 grassland species on plant community dynamics and structure over eight growing seasons. 2 Our goals were to: (i) test the importance of seed availability in regulating plant colonization dynamics and species richness;...
