Abstract
          A field experiment was conducted at Gemmeiza Agricultural Research Station, Agric. Res. Center, El- Gharbia Governorate during  two successive winter seasons (2011/2012 and 2012/2013) to study the effect of natural sources of phosphorus (Phosphorien and Rock phosphate) at three levels (50, 75 and 100 %) of the recommended dose (RD) and foliar application of Super Mex or Power Mix on some vegetative growth parameters, seed yield, fixed oil yield and chemical compositions in seeds of black cumin (Nigella sativa L.) plant.
The obtained results revealed that :
1- The highest values of plant height, capsules number/plant, seeds number/capsule, capsules weight/plant, 1000-seed weight, seed yield and fixed oil yield were achieved from the treatment of 50 % (Phosphorien plus Rock phosphate) + 50 % NPK in both seasons, while 75 % (Phosphorien plus Rock phosphate) resulted in the highest plant dry weight and  chemical constituents content.
2- Spraying with Super Mex (RD) + 50 % NPK resulted in the highest values of vegetative growth characters, seed yield, fixed oil of percentage, yield and chemical constituents in comparison with the foliar spray of Power Mix (RD) and the control treatments in both seasons.
3- The interaction treatment of 75 % (Phosphorien plus Rock phosphate) + Super Mex + 50 % NPK augmented values of plant height, capsules number/plant, seeds number/capsule, capsules weight/plant, 1000-seed weight, seed yield, fixed oil yield and chemical constituents in both seasons, while  Phosphorien plus Rock phosphate (50 %) induced in the highest plant  weight.
