“…Furthermore, choosing a suitable site based on agro-climatic and soil zoning should be seriously considered. The zoning maps in the semi-arid regions should be based on rainfall, temperature, absolute minimum temperature, evapotranspiration, soil texture, soil erosion, nutrient availability in soil, soil depth, soil water holding capacity, and physicochemical properties of soil (Nabati et al, 2020). However, the deficiency of some micronutrients such as zinc and iron are still evident in L2, improving the quality of seeds with the use of micronutrient fertilizers also confirms this point.…”

Biostimulants have been defined as substances or materials extracted from plants, which have the capacity to beneficially modify plant growth. Chickpea (Cicer arietinum L.) is an annual legume of the family Fabaceae and it is a rich source of vitamins, minerals, dietary fiber, and protein. Two field experiments were conducted in Northwestern Iran (L1: Maragheh and L2: Hashtroud) to determine the effects of farmyard manure (FYM) application (0 and 20 t/ha) and foliar application of bio-stimulants and chemical nutrients (acid salicylic, acid ascorbic, riboflavin, silicon dioxide nanoparticles, micronutrients, and distilled water as control) on nutritional characteristics of chickpea seeds. Results showed that there is a significant difference between seed quality of plant grown in two locations and the highest content of fatty acids (stearic acid, oleic acid, linoleic acid, linolenic acid), nitrogen, phosphorus, starch, and protein were recorded in seeds harvested from L2. Also, foliar application of micronutrient and silicon dioxide nanoparticles significantly increased dietary fiber, ash, starch, protein percentage. Concentrations of mineral nutrients (N, P, Fe, and Zn) significantly increased with the foliar application of micronutrients. Spray of acid salicylic and acid ascorbic increased the percentage of unsaturated fatty acids in both locations. Furthermore, the highest amount of flavonoid and crude oil was achieved by foliar spray of acid salicylic, silicon, and riboflavin. Although foliar spray of bio-stimulants and chemical nutrients improved seed quality in both locations, their positive effects were more pronounced in L2 where the soil and climate condition were partially better than L1. Overall, the best performance for major compounds of chickpea seeds was achieved by foliar spray of acid salicylic, micronutrients, and silicon dioxide nanoparticles in the FYM treatment. The present study indicate that improving the soil conditions is essential before foliar treatments.

“…3.4 Impact of land use on erosion Nabati et al (2020) utilized climatic, soil, and topographic variables to determine suitable areas for agriculture in Lorestan province. They found that only 19.88% of the province is suitable for irrigated agriculture and 54.2% for rainfed agriculture.…”

Floods cause great damage to ecosystems and are among the main agents of soil erosion. Given the importance of soils for the functioning of ecosystems and development and improvement of bio-economic conditions, the risk and rate of soil erosion was assessed using the RUSLE model in Iran’s Lorestan province before and after a period of major floods in late 2018 and early 2019. Furthermore, soil erosion was calculated for current and future conditions based on the Global Soil Erosion Modeling Database (GloSEM). The results showed that agricultural development and land use change are the main causes of land degradation in the southern and central parts of the study area. The impact of floods was also significant since our evaluations showed that soil erosion increased from 4.12 t ha-1 yr-1 before the floods to 10.93 t ha-1 yr-1 afterwards. Field surveying using 64 ground control points determined that erodibility varies from 0.17 to 0.49% in the study area. Orchards, farms, rangelands and forests with moderate or low vegetation cover were the most vulnerable land uses to soil erosion. The GloSEM modeling results revealed that climate change is the main cause of change in the rate of soil erosion. Combined land use change-climate change simulation showed that soil erosion will increase considerably in the future under SSP1-RCP2.6, SSP2-RCP4.5, and SSP5-RCP8.5 scenarios. In the study area, both natural factors, i.e. climate change and human factors such as agricultural development, population growth, and overgrazing are the main drivers of soil erosion.

“…Soil structure is partly responsible for the configuration of the pore network in the soil, which in turn determines the permeability of soil to air, water, and agricultural chemicals, as well as the ability of soil to store water. Together, these factors can create a suitable environment for the growth of crops (Nabati et al 2020;Kurshid, Iqbal, Arif, & Nawaz, 2006.…”

Field experiments were conducted to investigate the effects of residue and tillage on growth and yield of melon. Tillage treatments included conventional tillage (using a moldboard plough and two passes with a disk harrow), minimum tillage (one pass with a disk harrow), and no tillage (NT). Residue treatments included the application of 0%, 30% and 60% residue. Yield and yield components were obtained for all treatments. Tillage significantly affected yield and its components (P ≤ 0.05). The maximum FWPP (2.678 kg), NFPP (6.799), D (18.49 cm), L (45.93 cm), S (12.51%) and RUE (2.470) and yield (16.17 t/ ha) were recorded in the conventional tillage treatment. Also, maximum FWPP (2.192 kg), NFPP (5.353), D (16.66 cm), L (39.52 cm) and yield (12.83 t/ha) were observed in the 30% residue treatment. In terms of the interaction effects, maximum FWPP (2.850 kg), NFPP (6.790), D (20.71 cm), L (53.53 cm) and yield (17.09 t/ha) were obtained in the conventional tillage + 30% residue treatment. Therefore, the use of a moldboard plough followed by two passes with a disk harrow, in concert with 30% residue treatment, were maximizing the yield Almost all growth indicators had the optimum values in the conservation tillage treatments.
