Rapeseed (Brassica napus L.) is one of the oilseed crops in the temperate regions and is adapted to different climate conditions. This crop can have an important role in production of vegetable oil, and providing appropriate soil fertility can increase its seed and oil yield. In order to investigate the effect of N, P, K, Fe, Zn and Mn on seed yield and other agronomic traits of rapeseed, an ex...

With the increases of cropland area and fertilizer nitrogen (N) application rate, general N balance characteristics in regional agroecosystems have been widely documented. However, few studies have quantitatively analyzed the drivers of spatial changes in the N budget. We constructed a mass balance model of the N budget at the soil surface using a database of county-level agricultural statistic...

Sunflower (Helianthus annuus L.) can have an important role in vegetable oil production. Also, appropriate soil fertility is necessary to obtaine higher seed yield and quality of the crop. This experiment was conducted to investigate the effect of fertilizer treatments of macro and micronutrients on seed yield and other agronomic traits in sunflower. The effects of thirteen fertilizer treatemts...
