| This study was based on a long-term field trials of three different vegetable cropping systems (organic, low-input and conventional) in greenhouse which was initiated in 2002 at Quzhou Experimental Station of China Agricultural University, Hebei Province. The apparent nitrogen budget which equals to N input (nitrogen of fertilizer, transplants and irrigation) minus N output (nitrogen of the eggplants) was compared to provide the reference for the development of high yield and sustainable cropping system. The main conclusions were as follows: The total input of nitrogen in the organic, low-input and conventional systems was 1 150 kg·hm2, 1 182 kg·hm2 and 1 433 kg·hm2, respectively. The total nitrogen uptake by plants was 178 kg·hm2, 135 kg·hm2, 116 kg·hm2,... |
