Potential Use of Bio-Fertilizer and Stimulating Growth Compounds to Promote Rice Productivity

Abstract

Giza 179 Egyptian rice cultivar was grown at Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt, in 2014 and 2015 seasons; to study the influence of Cyanobacteria and Azospirillum as bio-fertilizer, foliar spraying with solution of simulative compounds (ascobein , humic acid and water) and three nitrogen levels (100%, 75% and 50% of the recommended chemical nitrogen fertilizer,69 kg N fed-1) on growth, yield attributes, yield and grain quality. The results show a positive effect of chemical N rate, biofertilizer and simulative compounds on crop growth rate (CGR), panicle numbers m-2 , 1000-grain weight, chemical ccompositions into milled grain such as protein and nitrogen content as well as grain and straw yields. Combination of 75% of chemical nitrogen fertilizer along with any biofertilizer or stimulating compounds were statistically at par with any combination containing the recommended nitrogen fertilizer (100% N) in the most of previous characters. Thus, it concluded that the application Cyanobacteria or Azospirillum with ascobien with humic acid as stimulating compounds as well as 75% of the recommended nitrogen dose could be used successfully to achieve optimum grain yield of Giza 179 Egyptian rice cultivar with saving 25 % of N fertilizer.

Evaluation of New Egyptian Japonica Green Super Rice Varieties Under Fertilization and Plant Spacing

“…When compared to other dosages, N330P72K120 or N165P36K60 had the maximum yield. The best conditions of all nutrients in the soil and the optimum growing environment for rice development and production may be achieved with balanced fertilization and prescribed dosages (Elekhtyar, 2007;Mantovani, et al, 2017;Sorour et al, 2018). Rice grain and straw yields were improved by using the ideal levels of chemical NPK fertilizers (El-Kramany et al, 2010;Elekhtyar, et al, 2016).…”

Effect of Foliar Application of Phosphorus, Zinc, and Silicon Nanoparticles along with Mineral NPK Fertilization on Yield and Chemical Compositions of Rice (Oryza sativa L.)

“…Nano fertilizer application promoted the growth, development, and antioxidant activity in rice and has the potential to improve crop production and plant nutrition [78][79][80]. The application of nanoparticles to plants can be beneficial for growth and development due to their ability for greater absorbance and high reactivity [13,81,82]. In general, when different nanoparticles could be applied on plant leaf surfaces in foliar feeding, they can enter through the stomata pores moving towards various plant tissues [83].…”

Effect of Plant Growth-Promoting Rhizobacteria and Cyanobacteria on Physico-chemical and cooking characteristics of Giza 179 rice grains

“…Azospirillum and Bacillus as PGPR may enhance rice biomass, root length, and NPK absorption (Kumar and Dangar, 2013;Elekhtyar et al, 2021). Germination, protein and amino acids, vitamins and nitrogen as well as other necessary components can be increased by 20 to 30 percent by increasing the number of microbes (Sorour et al, 2018;Mikael et al, 2021). Many types of cell wall components can be improved by microorganisms using enzymes such as enzymes that break down protein into amino acids (Lugtenberg et al, 2017).…”

“…Plant growth-promoting rhizobacteria and inorganic nitrogen fertilizer improve germination, seedling health, nitrogen absorption, grain production and grain quality when combined with inorganic nitrogen fertilizers. (Elekhtyar, 2016;Sorour et al, 2018).…”
