Organic and Inorganic Nitrogen Fertilization Effects on Some Physiological and Agronomical Traits of Chickpea (Cicer arietinum L.) in Irrigated Condition

Abstract

The effects of seed inoculation with Rhizobium and inorganic nitrogen fertilization on some physiological and agronomical traits of chickpea (Cicer arietinum L.) cv. ILC 482, were investigated at the Experimental Farm of the Agriculture Faculty, University of Mohaghegh Ardabili. The trial was laid out in split plot design based on randomized complete block with four replications. Experimental factors were mineral nitrogen fertilizer at four levels (0, 50, 75 and 100 kg urea ha -1 ) in the main plots, and two levels of inoculation with Rhizobium bacteria (with and without inoculation) as sub plots. N application and Rh. inoculation showed positive effects on physiological and agronomical traits of chickpea. The highest value of leaf RWC was recorded at 50 kg urea ha -1 what was statistically in par with 75 kg urea ha -1 application, while the usage of 75 kg urea ha -1 showed the maximum stem RWC. The maximum CMS was obtained from application of 75 kg urea ha ) and Rh. inoculation. Application of 75 kg urea ha -1 was statistically in par with 100 kg urea ha -1 in all of these traits. The results pointed out that some N fertilization (i.e. between 50 and 75 kg urea ha -1 ) as starter can be beneficial to improve growth, development, physiological traits and total yield of inoculated chickpea.

Yield and quality attributes with seasonal variation in Napier Bajra hybrid (Pennisetum purpureum × Pennisetum glaucum) under different nitrogen environments

“…Highest plant height (72.6 cm) was recorded at 100 kg N/ha doses while lowest (64.9 cm) at 50 kg N/ha doses. Increase in plant height with nitrogen fertilization of (0-180 kgN/ha), (0-30 kgN/ha) and (0-100 kgUrea/ha) also observed by other workers in pearl millet (Ayub et al, 2009), cowpea (Hasan et al, 2010) and Chickpea (Namvar et al, 2013) respectively. Among N sources, maximum plant height (cm) was observed with ammonium sulphate (69.9) application as compared to urea (68.4) and KNO 3 (68.0) treated plants (p>0.05).…”

Organic and inorganic fertilizer application enhances the effect of Bradyrhizobium on nodulation and yield of peanut (Arachis hypogea L.) in nutrient depleted and sandy soils of Ethiopia

“…These responses of grain yields to organic fertilizer are consistent with other studies on peanut such that there was a significant increase in peanut production by organic input enriched by fly ash (Burgos et al 2006). The benefits of organic fertilizer and inorganic fertilizer application in combination with rhizobia on the agronomic productivity of food legumes have been previously reported in chickpea (Namvar et al 2013;Shahzad et al 2013). The present results are also in accordance with the findings of Shahzad et al (2013) who demonstrated a significant increase in soil nutrients including available P by organic matter application.…”

Effects of <i>Rhizobium</i> Inoculation and Phosphorus Fertilizer Rates on Growth, Yield and Yield Components of Chickpea (<i>Cicer arietinum L.</i>) at Goro, Bale Zone, Oromia Regional State

“…It might be due to effective rhizobium strain increase leaf area which was being associated with more reproductive nodes. Similar results indicated that number of pods per plant was significantly affected with Rhizobium inoculation in chickpea [13,14]. These researchers noted that number of pod per plant was increased by 8.69 % more pods per plant than non-inoculated plants.…”
