Governorate to evaluate the productivity and quality of some Russian parsley varieties by using organic farming practices. Compost manure was added to the soil at three rates of 10, 15 and 20 m 3 /feddan. Seeds of different flat-leaf parsley varieties were sown (local, Leaf Breeze, Legendary Hero and Leaf Sandwich). The results showed that the increase in organic fertilization rates led to an increase in herb yield and its quality characters (chlorophyll pigment content in the leaves and essential oil yield). Despite the superiority of local variety in herb productivity, its quality parameters were low, while vegetative yield of foreign varieties was marked by high quality specifications (high chlorophyll content and essential oil yield). There were differences in constituents of essential oil between varieties. The response of plants to organic fertilization treatments was varied according to variety type. The best of the Russian varieties was Legendary Hero variety fertilized with 15 m 3 compost/feddan.
field experiment with split-plot design was laid out to investigate the effect of organic fertilization, foliar spray of yeast and their interaction on productivity and active constituents of three-lobed sage plants under Siwa Oasis conditions. The main plots included two compost manure levels of 10 and 20 m 3 per feddan. The sub-plots included foliar spray of active dry yeast concentrations of 0, 5 and 10 g /liter. The interaction effect proved that the highest compost manure level at 20 m 3 per feddan combined with foliar spray of the highest yeast concentration at 10 g/liter gave significantly maximum increments in vegetative growth parameters, yields of herb and essential oil as well as a higher 1,8-cineole constituent content in the volatile oil over control treatment, which recorded the lowest parameters.
ield research was conducted on Hyssop (Hyssopus officinalis L.) plants in the Mariout region, North of Egypt during the two successive seasons of 2020 and 2021. The purpose of the study is to determine the optimum space, chemical fertilization, and their interactions on the biomass yield. The research was set compatible to a split-plot design technique. The inter spacing was 30 and 50 cm, while the subplots had chemical fertilization at three levels: full dose NPK, 2/3 NPK, and 1/3 NPK. The used chemical fertilizers (full dose of NPK) were: 450 kg ammonium sulphate (20.5% N) + 300 kg calcium superphosphate (15.5% P2O5) + 150 kg potassium sulphate (48% K2O)/feddan. The results of the two cuts revealed that cultivation at a narrow spacing of 30 cm and adding a full dose of NPK recorded the significant highest production of herb and essential oil yield in the total area. The extracted oil contained pinocamphone (31.61-57.63%) and αpinene (20.47-49.88%) as principal compounds. Cultivation at 30 cm space and adding the full dose of NPK also improved the pinocamphone concentration in the essential oil better than other treatments.
his work was carried out during the two successive seasons of 2012/2013 and 2013/2014 to study the effect of different planting locations on three-lobed sage (Salvia fruticosa Mill.) plants. The experiment was conducted at three different locations in newly reclaimed lands as follows: El-Qantara Sharq (North Sinai Governorate), El-Maghara Village (North Sinai Governorate) and Siwa Oasis (Matrouh Governorate). The results indicated that all herb quantity and quality parameters were varied according to location and harvesting time. The best location for cultivation of this plant was El-Maghara location, which recorded the highest herb quantity parameters (number of cuts per season, fresh and dry weights of herb per plant or per feddan) as well as the highest herb quality parameters (essential oil yield per plant or per feddan with a suitable content of 1,8 cineole compound as the main chemical constituent of the oil), followed by El-Qantara Sharq location and then Siwa Oasis location.
Governorate to study the effect of organic fertilization and foliar spray with active dry yeast on growth, seeds yield and chemical constituents of Sinapis alba L. seeds. The experiment was carried out in split plot design. The main plots were consisted of three application levels of organic fertilization of 3, 6 and 9 ton compost per feddan. The sub-plots included foliar spray of active dry yeast at three concentrations (0, 3 and 6 g/liter). The interaction effect indicated that the application of the highest compost manure level of 9 ton/fed with foliar spray of the highest yeast concentration of 6 g/liter led significantly to the highest increments in plant height, dry weight per plant, number of siliquae per plant, seeds yield per plant and per feddan, fixed oil yield per plant and furthermore increased total protein content in the seeds over control treatment. Erucic acid was the main dominant fatty acid in fixed oil composition.
