Effects of biochar amendment and reduced irrigation on growth, physiology, water-use efficiency and nutrients uptake of tobacco (Nicotiana tabacum L.) on two different soil types

Xuezhi Liu et al.

Summary: Biochar has shown beneficial effects in agricultural production, and the addition of WSB combined with PRD may be a promising practice to synergistically improve tobacco yield, quality, and WUE by improving soil hydro-physical properties and nutrients bioavailability.

Effects of irrigation, nitrogen forms and topping on sun cured tobacco

Dursun Kurt et al.

Summary: The genetic potential, ecological conditions, and cultural practices play a significant role in determining tobacco yield and quality. The study focused on the effects of irrigation, nitrogen forms, and topping stages on the agronomic and chemical characteristics of oriental tobacco. Results showed that topping treatments can increase nicotine content in tobacco plants, while nitrogen forms and irrigation levels also impact the chemical composition.

Participation of urea-N absorbed on biochar granules among soil and tobacco plant (Nicotiana tabacumL.) and its potential environmental impact

Lin Zhang et al.

Summary: Overusing nitrogen fertilizers can have severe environmental impacts in agricultural fields. Utilizing biochar-based nitrogen fertilizers can increase crop yield and improve nitrogen use efficiency while reducing environmental harm. Coating biochar with straw powder can further enhance the retention of supplied urea-N in the root-zone, leading to better soil nitrogen accumulation and uptake by plants.
