Seventy five weaned NZW rabbits were used in growthtrial while, fifteen adult bucks were used in digestibility trials. The rabbits were divided into 5 similar and equal groups.  The 1st group fed control (CO) diet without medicinal plants, while those in the 2nd, 3rd, 4th and 5th groups were fed the pelleted diet containing 3% rosemary, 3% marjoram, 1.5% ginger root and 2.5% mixture (1%, 1% and 0.5%) of these medicinal plants, respectively. Daily body weight gain, feed conversion and dressing percentage improved (P<0.05) by 11.63, 1.73 and 3.01% due to rosemary diet; 17.83, 22.66 and 4.01% due to marjoram diet; 15.70, 11.35 and 3.51% due to ginger diet and 22.56, 7.53 and 3.51 % due to mixture diet, respectively. Digestibility coefficientsof DM, OM, CP and EE were increased (P<0.05) by 9.10, 6.36, 6.57 and 11.69 % due to rosemary diet; 7.61, 6.66, 7.18 and 11.50 % due to ginger diet and 7.41, 6.06, 6.14 and 9.61 % due to mixture diet, respectively. The digestibility coefficients of CF and NFE were not significantly affected by supplemented medicinal plants. The nutritive values of TDN increased (P<0.05) by 6.78 % due to rosemary diet. From an economic point of view, diets supplemented with marjoram, ginger and mixture medicinal plants could be used efficiently in feeding growing NZW rabbits can reduce production costs. Conclusively, the medicinal plants, Rosemary (Rosmarinus officinalis), Marjoram(Origanum majorana), Ginger root (Zingiber officinale) and their mixture could be added to NZW rabbit diets to improvegrowth performances traits and digestibility of nutrients under arid and semiarid conditions their addition within the limits recorded in this study is practically applicable, safe and beneficial.    }, keywords = {Rabbits,medicinal plants,rosemary,marjoram,Ginger,Growth,carcass,digestibility}, url = {https://jpd.journals.ekb.eg/article_42124.html}, eprint = {https://jpd.journals.ekb.eg/article_42124_249c85df9c40ce6e1402df7ef1eedff0.pdf} } @article { author = {Mohamed, Ghalia}, title = {STUDY ATITTUDE TOWARDS AGRICULTURE AMONG STUDENTS OF THE FACULTY OF AGRICULTURE IN OMAR El- MUKHTAR UNIVERSITY}, journal = {Journal of Productivity and Development}, volume = {21}, number = {1}, pages = {19-53}, year = {2016}, publisher = {Zagazig University.

During the present study an efficient in vitro protocol has been standardized viz, callus production from seedling explants. Best callus production from seedling explants was obtained on MS medium supplemented with 0.5mg/l NAA +0.05/1BA. Callus was also obtained when MS medium was fortified with 1mg/1NAA+0.5mg/1BA, 1mg/1 (2, 4D+0.5 mg/1BA and 3mg/l PCIB. But the percent culture response on these concentrations was lesser. The lowest amount of callus was found to be on MS medium containing 1mg/l PCIB 9(1) callus amount. Callus of explants were grown on half MS media gave the significant highest value (3641) of phenolic content, followed by callus of free-growth regulators MS medium (3509.5). While the lowest value (7) was observed with callus obtained from seedling cultured on MS medium contained 1 mg/1 2, 4-D+ 0.5 mg/1K. Conclusively, the Ammi visnaga callus formation can be obtained from different concentrations of growth regulators. The growth regulators also had a significant impact on the amount of callus produced.The efficiency of callus formation depended on the hormone concentrations and the proportion between NAA and BA. The best results were achieved on the medium containing 1mg/lNAA and 0.05mg/lBA.

Measured traits were number of leaves, plant height, leaf chlorophyll reading, leaf area, early and total yield, number of fruits, average number of fruit and N, P, and K percentage content of the fourth leaf. The results show that these vegetative growth parameters, yield and leaf chemical contents responded and positively significantly to using perlite: peat-moss under this investigation.
