Abstract
A field trial was conducted to determine the effect of nitrogenenriched biochar on soil water content plant’s photosynthetic parameters and grain yield of spring wheat at the Dingxi Experimental Station during the 2014 and 2015 cropping seasons Results showed that biochar applied with nitrogen fertilizer at a rate of 50 kg ha–1 of N BN50 increased soil water content in the 0–30 cm depth range by approximately 40 32 and 53 on average at anthesis milking and maturity respectively compared with zeroamendment CN0 Stomatal conductance and net photosynthetic rate after the BN50 treatment increased by approximately 40 to 50 compared to CN0 Soil water content and photosynthetic traits also increased in other treatments using straw plus nitrogen fertilizer but to lesser extent than that of BN50 Grain yields were highest 1905 and 2133 kg ha–1 in 2014 and 2015 respectively under BN50 From this biochar appears to have a potential for its use with Nfertilizer as a costeffective amendment for crop production in semiarid environments
