Impact of Livestock Manure, Nitrogen and Biofertilizer (Azotobacter) on Yield and Yield Components Wheat (Triticum Aestivum L.)

Abstract

Integrated nutrient management strategies involving chemical and biologic fertilizer is a real challenge to stop using the high rates of agrochemicals and to enhance sustainability of crop production. In order to study the effects of livestock manure, chemical nitrogen, and biologic (Azotobacter) fertilizers on yield and yield components of wheat, an agricultural experiment in the form of split factorial design with three replications was conducted in Elam region, Iran. The aim of this research was assessment of the effects of these fertilizers separately and in integrated forms; and setting out the best fertilizer mixture. The results showed that treatment with livestock manure, Azotobacter and chemical nitrogen increased plant height, biological and grain yield. Using livestock manure and Azotobacter increased biologic yield through increase in plant height which cause to increase in grain yield without any significant changes in harvest index and other yield components, but the use of chemical nitrogen caused an increase in plant height, No. of spikelete/spike, No. of grain/spike, one thousand grain weight and harvest index, biologic and grain yield. In the light of the results achieved, we may conclude that using livestock manure and chemical nitrogen fertilizer together with the Azotobacter had the maximum impact on yield; and that we can decrease use of chemical fertilizers through using livestock manure and biologic fertilizers and to reach to the same yield when we use only chemical fertilizers.

Biofertilizer (EM-1) effect on growth and yield of three bread wheat cultivars

“…This is maybe due to the increase in the number of spikes per square meter and the number of grain per spike (Tables 6 and 7). These results were similar to the Al-Juboory et al Esmailpour et al (2013) who confirmed the response of wheat to spraying with biofertilizer. Ibaa99 cultivar which had three times of EM-1 spraying gave the highest grain yield (4.11 and 4.58 ton*ha -1 ).…”

“…The best yield was obtained using EM-1 in the concentration of 1:500. Esmailpour et al (2013) noticed that using biofertilizer Azotobacter had led to an increase in grain yield of wheat (3,360 kg*ha -1 ) in comparison to the control (2,839 kg*ha -1 ). Ghaderi-Daneshmand et al (2012) found that using biofertilizer (biophospor and nitroxin) had led to significant differences in grain numbers per spike, and grain weight compared to the control, which eventually increased the final yield, in addition to the decreasing of the environmental pollution.…”

Effect of Different Nutrient Solubilizers on the Productivity and Economics of Grain Oat (Avena fatua L.)

“…On contrary, this result was confirmation of report by Singh et al (2005). These results were also confirmed by Esmailpour et al (2013), Mirshekari and Kauchebagh (2013). The current experiment finding was also in favour of results of synergistic effect of biofertilizers with chemical fertilizers on increasing the test weight of grains.…”

Influence of Mineral, Biological and Organic Nitrogen Fertilizer Regimes on Two Bread Wheat Cultivars Under Sandy Soil Conditions

“…Soil microorganisms are important components in the natural soil subecosystem because not only can they contribute to nutrient availability in the soil, but also bind soil particles into stable aggregates, which improve soil structure and reduce erosion potential (Shetty et al, 1994). Many authors have shown the positive effect of bio-fertilizers (Azotobacter and Azospirillum) on wheat (Ahmed et al, 2011;Abd El-Lattief, 2012;Esmailpour et al, 2013;Mohamed et al, 2013;Taher et al, 2013).…”

“…Sugar cane filter mud is a good source of available N when applied to soil and its application cane reduce the amount of fertilizer nitrogen required for optimum crop yield and play a role in decreasing the pollution effect of excessive N mineral fertilizer in soil (Arafat et al, 1997 andYassen et al, 2002), The use of organic fertilization had a positive effect on wheat where led to increased plant height, biological and grain yields (Abd El-Lattief, 2008;Abejehu, 2009;Ozturk et al, 2012;Esmailpour et al, 2013;Youssef et al, 2013;Zahoor, 2014).…”
