“…Chickpeas, like other legumes, create a nitrogen-fixing symbiosis with mycorrhizal bacteria (Hungria and Kaschuk, 2014). Many studies have shown that inoculating chickpea with beneficial bacteria improves growth indices and grain output, as well as seed quality (Pathak et al, 2017).…”

Since the introduction of laser leveler for land leveling in agriculture, farming community has been discussing the comparative role of different leveling implements in enhancement of crop growth and yield. Therefore, this study was conducted to determine the performance of chickpea (Cicer arietinum L.) crop under three leveling implements, including planker, iron blade and laser leveler. The research was carried out at the “Students’ Experimental Farm” of the Department of Agronomy, Sindh Agriculture University, Tandojam, Sindh, Pakistan, during winter season of 2021-22. The field experiment was thrice replicated in Randomized Complete Block Design (RCBD, factorial) on a net area of the plot (9 m2) per replication of each treatment, a total of 81 m2 per treatment. The results showed that land leveled under T3 (Laser leveler) resulted maximum growth and yield traits such as days to 50% germination (18.0), days to 50% flowering (47.53), days to 50% pod formation (77.53), plant height (72.63 cm), pods plant-1 (71.8), seed index (193.33 g), biological yield (4226.66 kg ha-1), grain yield (2550.0 kg ha-1) and harvest index (59.64 %), followed by T1 = Leveling with planker. While the minimum results recorded in T2 = Leveling with iron blade for all parameters. Therefore, land should be leveled with laser leveler to achieve the higher seed (grain) yield per unit area because it ensures uniform distribution of water, fertilizer, and ease in field operations.

“…Its tolerance to cold, drought, salinity and fires has enabled it to be classified among the most forest species used in the reforestation of arid and semi-arid zones (Derkaoui et al, 2016;Kheloufi et al, 2019). In addition, this hardy competitive legume species is nodulating with a vast number of Rhizobium strains, fixing atmospheric nitrogen (Amrani et al, 2010;Pathak et al, 2017). Furthermore, the species can establish a symbiotic partnership with many soil arbuscular mycorrhizal fungi (AMF).…”

The present study aims to evaluate the effects of the exotic shrub Acacia cyanophylla Lindl. on soil fertility by studying 1) its ability to modify the soil physicochemical composition, 2) its contribution to the soil mycorrhizal potential and its impact on the richness and diversity of the arbuscular mycorrhizal fungi (AMF) community in the rhizospheric soil (RS), and finally 3) its atmospheric nitrogen fixation potential. The physicochemical analysis of the RS has shown that soil invasion by A. cyanophylla has a beneficial effect on its fertility; this advantage is demonstrated by the increase of the organic matter and the nutrient contents (N, P, K, Na, Ca) in the RS. Furthermore, the roots of this shrub exhibited broad AMF colonization, which confirms its high mycotrophic aspect. Four differentiated morphotypes of mycorrhizal spores were isolated from the RS of A. cyanophylla by use of the wet sieving method. In addition, the most probable number method showed that A. cyanophylla was capable of dramatically increasing the mycorrhizal potential of the soil. Indeed, more than 1,213 infectious propagules per one hundred grams of soil were detected in the RS of A. cyanophylla. Moreover, A. cyanophylla roots showed a significant presence of nodules indicating an active atmospheric nitrogen fixation. Counting revealed the presence of at least 130 nodules in the root fragments contained in 1 kg of soil. In conclusion, the biological invasion of sand dunes by the exotic shrub A. cyanophylla exhibited beneficial effects on the soil’s chemical composition and functioning, the activity of rhizobacteria in fixing atmospheric nitrogen, and phosphate bioavailability under the action of the native AMF community.
