Effect of Using Agro-fertilizers and N-fixing Azotobacter Enhanced Biofertilizers on the Growth and Yield of Corn

Effect of Azotobacter on Growth and Yield of Maize

“…The lowest benefit of 0.3 % increase in yield by Azotobacter inoculation was obtained in the treatment applied with recommended dose of chemical fertilizer and Azotobacter inoculation over the recommended chemical fertilizer applied treatment. This result was in line with the Peng et al (2013), they concluded that Azotobacter chroococcum inoculation with maize seeds not only economically most efficient at lower doses of N but also saved N when applied in combination with FYM. Biari et al (2008) also found positive effect of Azotobacter application on maize grain yield increase at organic field condition.…”

“…Similarly, the highest stover yield (11.9 t ha -1 ) and lowest stover yield (3.83 t ha -1 ) were seen with the same treatments which produced highest grain yield and lowest grain yield. Peng et al (2013) also reported the positive effect of manure and Azotobacter application on maize biomass. The stover and grain yield were highly correlated in the experiment (not shown).…”

Effect of GA3 and Growing Media on Seedling Vigour and Physiological Parameter of Custard Apple (Annona squamosa L.)

“…It might be due to role of nitrogen enhancing persistence and longevity of LA, which is a key factor in terms of photosynthesis productivity of the plants, that assimilates higher amount of photosynthates production and if the mobilization is proper to the sink, it will enhance the economic productivity. The findings are supported by Peng et al, (2013). The effect of GA 3 had significant effect on Leaf Area Index and Leaf Area Duration Significantly maximum Leaf Area Index (1.11) and Leaf Area Duration (9715.76) were noted under 400 ppm (G 2 ).…”

The influence of foliar fertilization with nitrogen, sulphur, amino acids and microelements on spring wheat

“…Today, fertilizer manufacturing industry is highly specialised and advanced in this particular field and the range of foliar fertilizers manufactured is very broad. Positive influence of foliar fertilization with the recommended nutrients and biostimulants -N, S, amino acids and microelements on plant physiology was proved (Kalajia et al, 2014;Skwierawska et al, 2016) and was done field experiments with different plants (Brar, Kaur, 2006;Staugaitis, Petrauskienė, 2006;Peng et al, 2013;Mekdad, Rady, 2016). However, when applying foliar fertilization, soil and its agrochemical properties should be considered.…”

“…Fertilization through leaves with amino acids, microelements and sulphur influences plants favourably and increases the productivity of spring barley (Staugaitis, Petrauskienė, 2006;Pranckietienė et al, 2015), sugar beet (Mekdad, Rady, 2016), potatoes (Brar, Kaur, 2006), maize (Peng et al, 2013) and vegetables (Bundinienė et al, 2007). The experiments indicated that the productivity of spring wheat was increased by foliar fertilization with nitrogen, potassium and zinc fertilizers (Guenis et al, 2003;Zafar et al, 2016).…”
