| Abstract:
A field experiment was conducted focusing on the effects of biochar on quantity characteristics of Black Seed (Nigella sativa L. ) under water deficit conditions. The experimental design was split plot factorial in a randomized complete block design with three replications. Three levels of irrigation (I1: 100%, I2: 70% and I3: 40% of water irrigation requirement) were assigned as main plots and the combination of three levels of biochar (B1: 0, B2: 10 and B3: 20 t. ha-1) and two levels of chemical fertilizers (F1: without and F2: with chemical fertilizer) were allocated as sub plots. Results were shown that seed number per plant and seed weight per plant significantly increased by 10 t. ha-1 biochar application compared with 20 t. ha-1. Chemical fertilizer significantly affected the yield components of black seed except 1000-seed weight. The interaction between biochar, chemical fertilizer and water requirements significantly affected the seed yield and biological yield. The result revealed that the application of 10 t. ha-1 biochar plus 70% water irrigation requirement and using chemical fertilizer (I2B2F2) produced the highest seed yield and biological yield (1365 and 5776 kg. ha-1, respectively). Application of biochar combined with chemical fertilizers could improve soil nutrient and water availability conditions and increased the yield of black seed.
