200-120 kg/hectare on plant growth, green pod yield and it's components and the nutritive values of pea seeds cv. Master-B. The results showed that adding 22.5 m 3 /hectare caused a highest values of pea plant growth, i.e. plant height, number of leaves and dry weight of leaves, green pod yield of peas and its components, i.e. number of pods/plant, average pod weight, both of total green pod yield per plant and per hectare and number of seeds per pod, as well as the nutritive values of pea seeds, i.e. T.SS., ascorbic acid and total soluble sugars percentages. The highest values of different characters above mentioned were obtained by applying pea plants with 150-200-120 kg NPK fertilization per hectare. The interaction between organic manure at 22.5 m 3 cheep manure/hectare) and NPK fertilization (150-200-120kg/hectare), increased in most cases, growth parameters, green pod yield and its components of peas as well as the nutritive values of seeds. Conclusively, it could be concluded that the best treatment for high pea plant growth, green pod yield and its components as well as nutritional values of seeds were 22.5 m 3 cheep manure /hectare),150-200-120 kg / hectare NPK fertilization levels, and followed by the interaction between 22.5 m 3 cheep manure /hectare with 150-200-120 kg/hectare NPK fertilization.

Two field experiments were carried out at the Farm of Al-Zawia Zone-Libya in the winter seasons of 2006/2007 and 2007/2008 to study the effect of two microorganisms (Rhizobium bacteria and yeast fungi) and nitrogen fertilization (100kg/hectare urea, 46.5%N) on plant growth, green pod yield and its components, quality of pods and nutritive value of pea seeds, cv. Master-B. The experiment was included 8 treatments, i.e., control, dry yeast, rhizobuim, urea, yeast + rhizobium, yeast + urea, rhizobuim + urea and yeast + rhizobium + urea. The obtained results showed that the triple treatment of dry yeast, rhizobium and urea fertilization, being the most effective on increased plant growth (plant height and number of leaves/plant), green pod yield and its components (and number of pods/plant ,total green pod yield per plant and per hectare), quality of pods (pod length and number of seeds per pod) and the nutritive value of pea seeds (P and K-contents of seeds). In addition, there are no significant differences between the treatment of rhizobium + urea and dry yeast + rhizobium on average pod weight in the two growing seasons of study and on pod diameter in the first season only. In most cases, the triple treatment was the best on the most of studied characters, followed in descending order by rhizobium + urea and dry yeast + rhizobium. The lowest values of all studied characters was obtained by the control treatment. Conclusively, it could be concluded that the best treatments for high pea plant growth , green pod yield and its components , quality of pods and chemical contents of seeds (nutritive value) were yeast + Rhizobium + urea , followed by Rhizobium + urea , and yeast + Rhizobium.

The present experiment was carried out in greenhouse during 2018/2019 and 2019/2020 seasons to determine the effects of substrates media / combination and macro and micro nutrients within irrigation water. Uniform runners of strawberry cv. chandler were selected and planted in 12 and 13 th October 2018 and 2019 seasons, respectively, at a distance of 20 cm x 20 cm in 1m x 1m beds filled with eight different growing media combinations viz, sand (100%), peat moss (100%), vermiculite (100%), perlite (100%), peat moss: vermiculite (50% :50%), peat moss : perlite (50% :50%), vermiculite : perlite (50% :50%), and peat moss: vermiculite: perlite (33.3%: 33.3% : 33.3%) with three replications.The plants were irrigated at 1-2 days interval through micro drip irrigation during the initial stages and through drip irrigation during fruiting stages, while the treatments of macro and micro-nutrients dose of fertilizers were applied through fertigation using soluble fertilizers. The irrigation water was included two treatments, i.e. top water used as control, and fertilizer water which included macro and micronutrients, (%) i.e. N-P -K -Ca -Fe -Zn -B -Cu and Mn (

The present investigation was carried out during the two successive seasons of 2018/2019 and 2019/2020 at Abo El-Matameer, Behairah Governorate, Egypt to study the effect of seven treatments a foliar application, i.e. control (spray with water only), dry yeast at 2g/L, dry yeast at 4 g/L, urea at 0.5%, urea at 1.0%, urea at 1.5%, and urea at 2% on growth, yield and chemical content of lettuce plants.The experiment was arranged in a randomized complete blocks design in three replications. The obtained results are summarized as follows:Using urea and dry yeast extract levels as a foliar spray on vegetative growth characters, i.e. root length, head length, number of leaves/head, length and width of leaf, diameter of head , fresh and dry weight of head, pigments content ,chemical contents and head yield of lettuce and its components were significantly increased compared to the control treatment. The highest values of these characters of lettuce were recorded by using 1% urea, in both growing seasons. This treatment was followed by the treatments of dry yeast extract at 4 g/L, dry yeast extract at 2 g/L, and urea at 0.5%, respectively.Conclusively: It can be concluded that the treatment of 1% urea gave the best results on all characters of head lettuce. Key words: Head lettucefoliar spray with urea and dry yeast extract INTRODUCTION:Head lettuce (Lactuce sativa L.) is the world's most used salad crop. It is one the important leafy vegetable crops which are eaten fresh and is a major and extensively grown cool season vegetable best adapted to temperate locations (Rubatzky and Tamaguchi, 1997). It is taken as synonym of salads and contains about 6 -19% mineral elements on the dry weight basis. It is

Two field experiments were carried out in 2000 and 2001 seasons at the Experimental Farm (Cockle Park Farm) of the Faculty of Agriculture, Newcastle University to evaluate some cultivars of peas, i.e. Maro, Focus, Quasar and Flare, by studying of their growth characters, yield and its components as well as their photosynthetic activity. The results showed that Flare or focus had a higher growth rate of plant length and number of vegetative nodes, while Flare or Quasar, showed higher growth rate of both fresh weight of stem and tendril as well as total dry weight. In addition, green pod yield and its components of pea, i.e. number of pods/plant, number of seeds/plant, pod length and pod thickness were significantly increased in Maro or Focus. Moreover, focus had a greater photosynthetic activity on bottom leaves than the other studied pea cultivars at the first age (71 days from sowing) and the second age (93 days from sowing), while, Maro had a greater photosynthetic activity in the third age (100 days from sowing). On the other hand, on top leaves, cv flare in the first age, had a greater photosynthetic activity and cv Quasar in the second ones, had a good photosynthetic activity. On the contrary, at the third age, the different cultivars not appeared any clear promotion in characters of photosynthetic activity, i.e.e ref, delta e, c ref, delta c, Q leaf, U. Ci, E, 9s and A. Conclusively, it could be concluded that focus had a higher growth rate ,green pod yield and its components of pea, photosynthetic activity on bottom leaves at the first age and the second age.
