Effect of Organic Agriculture on Productivity of Some Russian Parsley Varieties Under North Sinai Conditions

Abstract

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.

Response of (Petroselinum sativum Hoffm.) To Organic, Bio-Fertilizer and some Foliar Application

“…Our results agreed, with the findings reported by Toaima et al; and (2018) on parsley, Azzaz et al;(2009) on fennel, (2012), Shirkhodaei et al; and Abdollahi et al;(2016) on coriander, Badran et al; on fennel, El-Sayed et al;(2017) on dill and El-Tarawy et al; on Caraway Essential oil analysis GLC analysis of parsley essential oil samples for the second season plants from the different treatments was illustrated in Table ( 6) and Figures (1&2). Twelve components were identified, most of them were hydrocarbons with low values compared to the oxygenated ones those had the high values.…”

“…In the same manner, on Syrian Cephalaria (Cephalaria syriaca) reported that total chlorophylls contents influenced by organic and biofertilization . Jahanshahi et al; on dill and Toaima et al; on parsley revealed the same observations.…”

“…The positive effect of organic and bio fertilizers on parsley vegetative growth characters may be due to that, the mixed application of different sources of fertilizers influences trace elements (Zn, Fe and Cu) uptake optimally, has useful effects on soil physical and chemical properties and leads to maximum plants quality with a good source of nutrients (Rahimi et al;Darzi, 2012 ). Also, Toaima et al;2014 on parsley, Khalil et al; 2008 on Fennel and Salvia reported that, the increase in organic fertilization rates significantly increased the vegetative growth and quality characters plants.…”

“…Many researchers pointed out efficacy of organic manures and biofertilizers on increasing the plant vegetative growth and yield and recommend that completely or partial replacement of NPK mineral fertilization like Toaima et al; and (2018) Dealing with the effect of different FYM rates, biofertilizers and their interaction treatments on number of umbels/plant, seed yield/plant, seed index and essential oil percentage in both seasons data were shown in Table (5) The results revealed that the previous yield characters were significantly affected by the different FYM doses in both seasons. The largest number of umbels per plant (15.27 and 16.33), heaviest seed yield/plant (13.57 and 14.74 g), 1000-seed weight (2.17 and2.36g) and essential oil percentage (3.72 and 4.32%) in the two seasons, respectively were of 6 t./fed treatment plants followed by 4 t./fed plants.…”

“…Many researchers achieved best growth, yield, oil percentage and yield and constituents when used organic manures and different biofertilizers for several medicinal and aromatic plants, like (Toaima et al; and (Tursun et al; on parsley, 2018) on parsley, ( Patel et al;2010) and (Badran et al; on fennel, on Fennel and Salvia, (El-Tarawy et al; on Caraway.…”
