Deficiencies of zinc, manganese and iron are common in calcareous soils of arid and semiarid regions due to their reduced solubility alkaline conditions. However, sustainable crop production is essential for growing population. Sulfur fertilizers can increase micronutrients availability by decreasing soil pH. In order to investigate the influence of nano-chelated essential metals (Zn, Mn, Fe) and sulfur application (zero and 40 kg ha-1) an experiment was carried out in Maragheh, northwest of Iran. Phenological development, morphological and agronomic traits significantly responded to both factors. Results revealed that application of sulfur fertilizer considerably increased morphological traits such as ground cover, stem diameter, plant height and capitulum diameter. Mean comparison between nano-chelated metal showed that the highest value for seed yield and yield components (number of the capitulum per plants, seed number per capitulum and seed weight) was achieved through the application of nano-chelated Zn. The best performance was related to combined application of sulfur and nano-chelated Zn which was followed by nano-chelated Fe. Seed oil content was only affected by nano-metals, so the highest value was obtained by application of nano-chelated Zn. Overall our finding revealed that integrated application of sulfur and essential metals, especially Zn, is required to grow safflower successfully on calcareous soils. The efficiency of nano-chelated fertilizers can be noticeably increased by balanced nutrient management in semi-arid regions.

The catalogue contains the results of protein content assessment in seeds of 216 common bean (Phaseolus vulgaris L.) accessions from the VIR plant genetic resources collection. The data of a long-term study with mean values of characters for each accession are presented. The study of main agronomic characters in the accessions was conducted from 2004 through 2018 in the experimental fields at Astrakhan Experiment Station of VIR. The accessions are described employing eight morphological and agronomic characters important for breeding practice. This catalogue is intended to serve as a tool in source material selection for further breeding process. It may prove helpful for plant breeders and grain legume experts.

Effects of row spacing, blended fertilizer rates, and varieties on some agronomic traits of chickpea were evaluated with the objective of investigating response of Kabuli and Desi type chick pea varieties to blended fertilizers rates and interrow spacing. The study was done using split plot design interrow spacing as a main plot, and fertilizer and variety as a subplot, where three row spacings (20 cm, 30 cm, and 40 cm) were assigned to the main plot while the factorial combination of four blended (NPSB) fertilizer rates (0 kg/ha, 50 kg/ha, 100 kg/ha, and 150 kg/ha) and representative of Kabuli and Desi type chickpea varieties such as Arerti and Mariye, respectively, were assigned to the subplot. Main effect of interrow spacing did not show significant difference on many studied agronomic parameters. Similarly, main effect of blended fertilizer rates and varieties did not reveal a significant difference for the studied parameters. However, significant differences were obtained on phenology, yield components, and yield for the varieties. Blended fertilizer rates utilized in Tselemti District did not show differences in most of studied traits. Reasonable row spacing of 20 cm for both types of chickpea could be used for the studied area.

Abstract Essential oils (EO) of several plant species have the potential to combat plant and fungal diseases. However, the effects of Achillea millefolium EO on the development of common bean (Phaseolus vulgaris L.), is still unknown. Moreover, its effect on N2-fixing bacteria, and in general on soil properties has not been studied yet. A greenhouse trial was set up to evaluate both the influence that Achillea millefolium EO and the inoculation with three different Rhizobium strains have on the bean plant and on the chemical and microbiological properties of an agriculturally used Cambisol. Non-inoculated pots were used as control. Our findings showed a decrease in bacterial colony forming units due to EO application and an increase following the Rhizobium inoculation compared to the control. The EO application decreased soil basal respiration and activities of dehydrogenase, urease, β-glucosidase and acid phosphatase. Such effects were stronger with higher oil concentrations. Moreover, the treatments combining Rhizobium inoculation with EO showed a positive effect on nodulation and plant height. Overall, the combined application of Achillea millefolium EO and rhizobia works as an efficient biocide that could be applied in organic agriculture without hampering the activity of nodule-forming N-fixing bacteria and the development of common bean.

Farmers in Northern Ethiopia integrate legumes in their cropping systems to improve soil fertility. However, biological nitrogen fixation (BNF) potentials of different legumes and their mineral nitrogen (N) and phosphorus (P) demands for optimum BNF and yields are less studied. This study aimed to generate the necessary knowledge to enable development of informed nutrient management recommendations, guide governmental public policy and assist farmer decision making. The experiment was conducted at farmers’ fields with four N levels, three P levels, and three replications. Nodule number and dry biomass per plant were assessed. Nitrogen difference method was used to estimate the amount of fixed N by assuming legume BNF was responsible for differences in plant N and soil mineral N measured between legume treatments and wheat. The result revealed that the highest grain yields of faba bean (2531 kg ha−1), field pea (2493 kg ha−1) and dekeko (1694 kg ha−1) were recorded with the combined application of 20 kg N ha−1 and 20 kg P ha−1. Faba bean, field pea and dekeko also fixed 97, 38 and 49 kg N ha−1, respectively, with the combined application of 20 kg N ha−1 and 20 kg P ha−1; however, lentil fixed 20 kg ha−1 with the combined application of 10 kg N ha−1 and 10 kg P ha−1. The average BNF of legumes in the average of all N and P interaction rates were 67, 23, 32 and 16 kg N ha−1 for faba bean, field pea, dekeko and lentil, respectively. Moreover, faba bean, field pea, dekeko and lentil accumulated a surplus soil N of 37, 21, 26 and 13 kg ha−1, respectively, over the wheat plot. The application of 20 kg N ha−1 and 20 kg P ha−1 levels alone and combined significantly (p < 0.05) increased the nodulation, BNF and yield of legumes; however, 46 kg N ha-1 significantly decreased BNF. This indicated that the combination of 20 kg N ha−1 and 20 kg P ha−1 levels is what mineral fertilizer demands to optimize the BNF and yield of legumes. The results of this study can lead to the development of policy and farmer guidelines, as intensification of the use of legumes supplied with starter N and P fertilizers in Northern Ethiopian cropping systems has the multiple benefits of enhancing inputs of fixed N, improving the soil N status for following crops, and becoming a sustainable option for sustainable soil fertility management practice.
