Abstract

Microwave (MW) soil heating has been shown to deplete the soil weed seedbank and increase crop productivity. However, the impact of MW soil heating on the nutritive value of crops is unknown. In this study, two field trials were conducted to evaluate the effect of pre-sowing MW soil treatment with a duration of 60 s and an untreated control, which were assigned in a randomized complete block design with five replicates at two locations, on the yield and nitrogen (N) accumulation pattern of rice crops. At Jerilderie site, soil heating at up to 70–75 °C significantly (p ˂ 0.09) increased the rice biomass yield by 43.03% compared with rice biomass yield in untreated soils, while at Dookie site ..
