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

“…However, in Spencer et al (1983) no method for preparing an effective yeast extract is given. Farrag et al (2016) followed the method of Ono et al (1991), where Yeast Peptone Glucose (YPG; 2% glucose, 2% peptone, and 1% yeast extract) medium was used for the propagation of yeast cells. The growth temperature was 30 °C.…”

This review focuses on yeast suspensions applied with the aim to enhance nutritional content of agricultural products. Seventy one publications were studied, and their details summarized in tables, according to the following plant groups: 1/ arable plants, 2/ vegetables, 3/ medicinal and ornamental plants. It was found that the experimental designs in these papers were inconsistent in most cases and, regardless to plant species used, the concentration of yeast extract, time of application, and repetitions of the treatment were fundamentally different, making evaluation of the methodologies difficult. However, all studies agreed in the positive impact of yeast extracts on nutritional parameters. Therefore, it is advisable to perform further studies to clarify the relationship of individual nutritional parameters to spraying dose, timing and repetition of yeast application.

“…Flores-Félix et al 2013, used a biofertilizer inoculated with Rhizobium leguminosarum and found a nitrogen concentration of 37.2 g kg -1 in plant tissue of romaine lettuce. Farrag et al (2016) tested different doses of conventional fertilizer along with a foliar fertilizer and recorded a concentration of 43.3 g kg -1 for this nutrient. Resende et al (2009) observed that N doses higher than 120 kg ha -1 N applied to lettuce resulted in an increase in the N concentration.…”

Curly lettuce development, nutrient absorption and salinization tolerance in response to an aerobic biofertilizer produced from agro-industrial residues

Biofertilizers stimulate natural processes to increase and benefit nutrient absorption, abiotic stress tolerance and increased yield when applied to plants. The production of biofertilizers from organic residues is a sustainable way to reduce these materials through recycling. The aim of this work was to define the biofertilization management based on concentrations and doses using a non-commercial aerobic biofertilizer on three newly emerged Brazilian lettuce cultivars. Consequently, this study will help to improve organic lettuces yields in the country. The experiments were conducted in a greenhouse. The soil used for cultivation was a clayey Rhodic Ferralsol. Due to the high electrical conductivity (EC) observed in the biofertilizer a first experiment was conducted to determine the optimum concentration (0%, 5%, 10%, 15%, 20% and 100%) for the three lettuce cultivars (BRS Leila, BRS Lélia and BRS Mediterrânea). After finding the best concentration, a second experiment was developed to estimate the optimum dose of the biofertilizer based on the nitrogen requirement (N) for this crop (0 kg ha-1 of N, 50 kg ha-1 of N, 100 kg ha-1 N, 150 kg ha-1 N and 200 kg ha-1 N). The experimental design was completely randomized (DIC) with a factorial scheme. The results showed that 5% concentration of biofertilizer presented better results for the development of BRS Mediterrânea and BRS Lélia. BRS Leila presented better development when fertilized with the 10% biofertilizer concentration. The dose of 150 kg ha-1 of N allowed a better development of lettuce and greater supply of nutrients to the plants.
