Effect of Foliar Application of Yeast on Yield and Seed Quality of Some Rice Cultivars

Abstract

and 2013 seasons to study the effect of 5 concentrations of dry yeast (Saccharomyces cervisia) i.e. 0, 2, 4, 6 and 8 g/L as foliar application at 25, 55 and 85 days after sowing on growth characters, yield and its components of Giza 178, Sakha 105 and Sakha 106 rice cultivars. The produced seeds obtained from the field experiment were investigated under Laboratory condition to study seed quality characters) seed, seedling vigor and its health) at Seed Technology Research Unit in Mansoura, Egypt. Results revealed that Giza 178 cv. was significantly thumping as compared with other studied cultivars in all studied characters of both growth and yield components. Maximum growth and yield components were produced from foliar spraying with 6 or 8 g/L dry yeast where show enhancement in heading date, plant height, number of tillers, and increased dray matter, number of panicles, panicle length, 0111 grain weight and grain yield with high significant in both seasons. The data of seed and seedling vigor test showed that Giza 078 cv. gave the highest values of normal seedlings (GP), speed germination (SG), seedling length (SL), while Sakha 011 cv. gave the highest values of dry weight followed by Sakha 016 cv. as compared with other cultivars. On the other hand, foliar spraying with 6 or 8 g/L dry yeast were the best treatments of seed and seedling vigor as compared with control and other concentrations of dry yeast and also decreased abnormal seedlings and seed rot percentages with significant effect. Seed health test recorded thirteen fungus species were associated with seeds of three cultivars under study. Giza 178 cv. was the less values of total fungi, followed by Sakha 016 and Sakha 011 cvs. Alternaria padwickii showed maximum values presented on seeds of three cultivars followed by Bipolaris oryzae, A. longesima, Fusarium semitectum, A. tenuis, F. graminearum and Sarocladium oryzae … et. The beneficial effects of yeast lead to lower the number of seed-borne fungi with increasing concentration from 2 to 8 g/L especially pathogenic fungi which caused reduction to seed and seedling vigor of rice. It could be recommended that use of foliar spray with dry yeast (S. cervisia) at 6-8 g/L at 25, 11 and 85 days after rice sowing gave the highest values of yield, yield components and next enhanced seed, seedling vigor and lower numbers of seed-borne fungi associated with rice seeds(seed quality

Enhance Sunflower Productivity by Nitrogen Fertilizer Sources and Antioxidants Foliar Application under Sandy Soil Conditions of Toshka Region

“…Treating plants with various substances including A 3 , A 2 and A 4 produced about (16.25 and 23.03 %), (9.38 and 14.47 %) and (8.75 and 13.16 %) more seed yield than untreated plants (A 1 ) in 2017 and 2018 seasons, respectively. Dewedar and Ibrahim (2016) found that foliar application of dry yeast on rice gave the highest values of yield and yield components. The positive effect of yeast extract upon seed yield attributed to the early vigorous growth of sunflower plants (Tables 4 and 5) Results presented in Table (6) showed that spraying sunflower plants with some compounds caused significant promotion of seeds quality of sunflower, i.e., , oil yield, oil %and protein% particularly in yeast extract (A 3 ) treated plants to about (27.72 and 28.94 %), (10.11 and 4.75 %) and (13.79 and 12.29 %) above the control value during the two growing seasons, respectively.…”

Integrated biofertilization using yeast with cyanobacteria on growth and productivity of wheat

“…On the other hand, yeast acts as biological stimulator to growth due to production of growth promoting substances, and has high ability to make active association with the non-leguminous crops such as rice, sugar beet and wheat [24,25]. Foliar spray using yeast (Saccharomyces cerevisiae) increased rice yield components, improved seed quality and decreased seed-borne fungi [24].…”

“…The yeast species Saccharomyces cerevisiae is an ecofriendly and natural biological stimulator for plant growth. Previous reports elucidated the high efficiency of yeast extract to increase plant growth, yield components and grains quality of different crops such faba bean [23], rice [24], sugar beet [25] and maize [26]. As a result, the development of biofertilizers using a combination of two or more microorganisms such as cyanobacteria-bacteria or bacteria-bacteria has been found to enhance wheat height, dry weight, and grains yield [16,17,21,27].…”

Effect of Micronutrients Application and Spraying Yeast Extract on Yield and Yield Components of Wheat (Triticum aestivum L.)

“…Yeast (Saccharomyces cerevisiae) is a living organism (fungi) that contains many important nutrients for plants such as iron, calcium, magnesium, potassium, nitrogen, sodium, phosphorus, zinc and silicon (Table 2). It is rich in growth regulators such as gibberellins and oxins (De Wedar & Ibrahim, 2016). It was found that AYE increase vegetative growth such as plant height and leaf area (Ezz El-Din & Hendawy, 2010).…”
