The effect of farmyard manure (FYM) at 10, 15 and 20 m 3 /fed. Effective microorganisms (E.M.) and/or vitamin E or vit. B1 treatments on oil production (essential oil % and essential oil yield/plant and /fed) and chemical components (photosynthetic pigments content and NPK %) were investigated during 2015/2016 and 2016/2017 at Samalot region (El-Byaho village)-Minia Governorate and Laboratory of ornamental plants, Fac. of Agric., Minia Univ. All treatments of FYM statistically increased oil production as well as chemical components as compared with control. The high level of FYM was more effective in this concern. The treatments of E.M. + vit. B1 followed by E.M. + vit. E, then mineral NPK (full dose) gave the best results in increasing all previous traits. Supplying cumin plants with FYM at 20 m 3 /fed. in combination with E.M. + vitamins (B1 or E) or FYM at 15 m 3 /fed. plus E.M. + vit. B1 resulted overall the highest values of the previous traits.
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.
The effect of farmyard manure (FYM) at 10, 15 and 20 m 3 /fed E.M. and/or vitamin E or vit. B1 treatments on vegetative growth (plant height, number of branches/plant and dry weight of herb/plant), yield (number of umbels/plant, fruit yield/plant and /fed) of cumin plant were investigated during 2015/2016 and 2016/2017 at Samalot region (El-Byaho village)-Minia Governorate and Laboratory of Ornamental Plants, Fac. of Agric., Minia Univ. All treatments of FYM statistically increased vegetative growth characters and fruit yield as compared with control. The high level of FYM was the most effective in this concern.

Supplying cumin plants with FYM at 20 m 3 /fed in combination with E.M. + vitamins (B1 or E) or FYM at 15 m 3 /fed plus E.M. + vit. B1 resulted overall the highest values of the previous traits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
