Pepper cultivation is one of the vegetables that are widely produced in the world. The use of mycorrhiza in sustainable agriculture can be an environmentally friendly and economical agriculture strategy. The purpose of the study; is to investigate the effect of mycorrhiza inoculation on plant growth development, yield and mycorrhizal dependency. The hypothesis to be tested is; inoculation of mycorrhiza increases pepper plant growth parameters. The experiment was established as a pot experiment under greenhouse conditions in February 2018 and harvested in April 2018. BT 16-90 F1 pepper (Capsicum annuum L.) species seeds were used with mycorrhiza Claroideoglomus Etunicatum and without mycorrhiza inoculation with three replications. Before harvesting, plant height and leaf diameter were measured. At harvest, the dry and fresh weights of the root and shoot were measured. In addition, some of the root morphological properties (like root diameter, root length, root surface area and root volume) were determined by using WinRhizo program. In addition, mycorrhizal root infections were determined. Mycorrhizal dependency was calculated by using dry matter data. Research findings showed that mycorrhizal inoculation increased pepper plant root, shoot fresh and dry weight, plant height, and leaf diameter. In addition, the root length of the plants with mycorrhiza inoculation (as 3921 cm pot-1) was higher than without mycorrhiza (with 1945 cm pot-1) treatments. The pepper plant has a high mycorrhizal dependency (71.9%) with Cl. Etunicatum inoculation. The results shown that Cl. Etunicatum inoculation increased pepper plant growth and development. Also, the pepper plant is a highly mycorrhiza-dependent plant.

Field studies were conducted on carbonate chernozem in Vojvodina Province of Serbia during two seasons of maize growing to adjust nutrient management practices when fertilizers are broadcasted and incorporated into the soil before sowing. The experimental scheme included six fertilization treatments: T1 (zero fertilizer control), T2 (N156P64K64, farmer fertilizer practice), T3 (N100P60K60), T4 (N100P60K60S36), T5 (N100P80K60), and T6 (N100P80K60S48). Nitrogen application practice was found to be excessive, while phosphorus application practice was found to be insufficient. Phosphorus application rate of 80 kg P2O5 ha-1 was found to be rational when the soil test for phosphorus was very low or low. Sulfur (S) application improved grain yield in higher yield conditions, whereas soil containing 3.9–4.0% of organic matter (OM) could meet crop S requirements in lower yield conditions of 5 t ha-1 and below. It is assumed that S application to maize in the southern Pannonian Plain in Serbia may be limited to 36 kg S ha-1.

Anthracnose fruit-rot samples were randomly collected from 95 chilli farms grown in different hotspot regions from following states. Survey was conducted during Kharif 2020 from Andhra Pradesh, Karnataka, and Tamil Nadu, while during Kharif 2021 from Maharashtra, Madhya Pradesh, and Chhattisgarh. Samples were analyzed based on morphological characters. After morphological characterization of collected samples, it was confirmed that 80 fields were infected alone with C. capsici, 7 fields were infected alone with C. gloeosporioides while 8 fields were mixed infected with both C. capsici and C. gloeosporioides. Anthracnose infection mainly affects chilli at red fruit stage. Morphological characterization of collected samples from the surveyed region revealed that Colletotrichum capsici and C. gloeosporioides were the major species infecting chilli while Colletotrichum capsici was the predominant species. As C. capsici is predominant species causing Anthracnose, we need anthracnose resistant source at least against C. capsici. Resistant source against both C, capsici and C. gloeosporioides will be a boon for breeders to strengthen disease resistance

: Irrigation scheduling is the use of water management strategies to prevent over-application of water while minimizing yield losses due to water scarcity or drought stress. The experiment was conducted in Odo Shakiso district at a farm during the 2020/21 and 2021/22 irrigation seasons with the aim of determining the optimal irrigation schedule for yield, yield component and water productivity of onions based on the available soil moisture depletion levels. The experiment was performed in RCBD with three replicates randomly assigned to experimental plots with treatments. Five available soil moisture depletion levels (20% ASMDL, 40% ASMDL, 60% ASMDL, 80% ASMDL and FAO recommended ASMDL) were used for treatment. Results from two years of research showed that different levels of available soil moisture had a significant impact (P<0.05) on bulb diameter, bulb weight, unmarketable onion yield, marketable onion yield, and water productivity. However, different soil moisture depletion did not show a significant difference in plant height. The highest onion diameter (4.25 cm) and marketable onion yield (363.9 qt/ha) was recorded at 60% ASMDL. The highest water use efficiency at marketable onion yield (9.487 kg/m 3 ) was also achieved at 60% ASMDL, which was statistically comparable to the FAO-recommended ASMDL treatment. On the other hand, the minimum water use efficiency (6.234 kg/m 3 ) was recorded at 40 percent ASMDL. Therefore, based on the results of the current experiment, it is recommended to use 60% ASMDL under a furrow irrigation system for onion cultivation in areas around Shakiso and similar agro ecologies as it is the best option to increase yield and water use efficiency for onion production.

Livelihoods diversification strategies are one means of meeting the overgrowing world population’s food demand. This study identified household-level determinants of livelihood diversification strategies and its impact on food security status in North Shewa, Oromia, Ethiopia. Both primary and secondary data about the 2021/22 production year were collected for this study. Primary data was collected from 400 smallholder farmers that were collected using a simple random sampling technique. Descriptive statistics and econometric models were used for data analysis. Looking into the estimated coefficients, the results indicate that livelihood strategy is significantly influenced by fourteen explanatory variables. Agro ecology, sex, family size, farm size, economic active member, training, credit access, livestock holding, education level, experience in farming, irrigation experience, media, distance from the market were significant variables that affect the household livelihood strategy status. Impact evaluation estimated result indicated that participation of farming with non-farming livelihood diversification strategies increases farm household food security status by 25% while, participation in farming with off farming and farming with both non-farming and off farming livelihood diversification strategies increases households' food security status by 43 and 37% respectively over non-diversified households at a 1% probability level. This study indicated that there is room to improve rural households’ level of food security status using more of the aforementioned socio-economic variables. Therefore, policymakers should give due emphasis to the identified variables and improve the livelihoods of rural households.
