COVID-19 pandemic has made the future uncertain for many in general, but students in particular because institutes suddenly shutting down, while this new transition has hit everyone differently. Still, it has left significant pressure on the students specifically. This pandemic has changed the ways of living - financially, physically, emotionally, and mentally. This study analyses the impact of COVID-19 on students' mental health. It covers the globe, how they have been dealing with it, and which coping mechanisms worked best for them during this time. The study also discussed how different financial backgrounds had left a different psychological impact on the students. The methodology adopted utilizes all the previous research and their data, which helped us determine the most worked solution vs the least worked solution. In addition to literature, data from UNICEF about education and COVID-19 are utilized to determine the adverse impact of COVID-19. This study has also briefly touched on the impact of remote learning on students' mental health and how students have coped with this sudden yet uncertain new change. The research has come up with some proven solutions for students to perform better academically during this uncertain time without compromising their mental health.

Aquaculture systems and technologies are growing industries in many countries with high environmental and socio-economic advantages. Afghanistan, a landlocked country in South Asia with diverse geographic and ecological features, reported the lowest fish consumption rate (just above 2 kg per capita). After conflicts and instability in Afghanistan, aquaculture and fisheries sectors revived slowly, followed by a rapid production and demand increase in the last four years. However, Afghanistan can demonstrate with a long history of fishery and agriculture productions in the past, but the post-conflict and stability efforts are minimal. Therefore, Afghanistan's aquaculture and fisheries sectors are conventional and require more effort to study and propose viable solutions aligned with today’s technological and sustainability requirements. Adequate and historically documented information about Afghanistan's aquaculture and fisheries activities are pretty limited. This study covers previous aquaculture initiatives, establishes a thematic review of the current situation based on little available information, and follows by a foresight outlook of the future trends.  Besides, it presents the essential factors associated with production-efficient aquaculture and fishery systems in light of economic and production performance indicators. These indicators are briefly discussed that contribute to system planners and practitioners in decision-making and optimizing economic and operational efficiencies. Besides of studying Afghanistan aquaculture and fishery sectors, the basic criteria for successful small scale aquaculture are also presented that can be counted as one of the recent compositions of the subject in terms of scholarly managed information within an exhaustive insight.

Onion botanically named Allium cepa L. is a major crop of Alliaceae family. It is one of the largest commercially grown vegetables in the world including Afghanistan. This crop originated from Afghanistan and large number of its wild varieties are observed in the country. Local variety named Safid e Paisaye was selected for this investigation due to its capacity of longer storage and higher demand in the market. Very less research efforts are made to improve its bulb quality and share in the market. This investigation is carried out at Kabul university agriculture research farm in coordination with Amity University Uttar Pradesh, to study the effect of land management and planting date on bulb physical properties of onion. The parameters studied in this investigation include bulb width (cm), length (cm), thickness (cm), geometric mean diameter, arithmetic mean diameter, shape index, sphericity, roundness, ellipsoid ratio, frontal surface, cross sectional area, total area, number of scales, equatorial firmness (Kg/cm²) and polar firmness (Kg/cm²). The data is collected using required tools and was analyzed using R statistical analysis software. The results showed significant effect of planting date on physical properties of onion bulb. The first planting date (10^th May) recorded the largest bulb width (6.95 cm), length (4.42 cm), thickness (6.75 cm), geometric mean diameter (5.91 cm), arithmetic mean diameter (6.04 cm), frontal surface (24.26 cm²), cross sectional area (28.84 cm²) and total area (110.63 cm²). The same planting date recorded the lowest values for bulb shape index (0.64) and sphericity (0.85). Land management practices did not have significant effect on physical properties of onion bulb. None of the studied factors had significant effect on bulb roundness, ellipsoid ratio, number of scales, equatorial firmness and polar firmness. Conclusions: early planting of Safid e Paisaye onion seedlings can increase bulb size and improve bulb physical characteristics. This also helps to maintain the flat and round shape of onion bulb. Land preparation method and plough depth do not have significant influence on physical properties of onion bulb.

The Zero Energy Cool Chamber (ZECC) is the needed evaporative cooling system introduced as one of the economical small scale on-farm storage in Afghanistan for enhancing the shelf life of tomato and other fresh crops. Tomato is one of the highest value crops, and due to excellent flavor, higher juice, and pulp content of tomato fruits of “Pearson” variety makes it further valuable. Hence, this study aims to understand the effect of ZECC and postharvest treatments on shelf life and quality of tomato’s fruits harvested at turning and light red colors’ stages. Fruits were treated with different concentrations of CaCl₂ and mint leaf extract solutions and kept in both ZECC and ambient storages. The shelf life of tomato fruits extended up to 29 days under T₄ (turning color fruits + 6% CaCl₂ + ZECC). Under the same treatment, the highest firmness as 840.0 grcm^-2   and the lowest PLW, Decay Losses and TSS were recorded as 1.80%, 0.0% and 4.40⁰ brix, respectively; on the 20^th day of the storage. The lowest shelf life under T₁₁ (Light red color fruits + distilled water dip + Ambient condition) was about 8 days. As a result, the ZECC as an evaporative cooling system significantly enhanced the shelf life and maintained the quality of tomato fruits harvested at the turning color stage treated with 6% CaCl_2.

Tomato (Lycopersicon esculentum Mill) is one of the important commercial high value crops of Afghanistan. Among the different local varieties grown in Afghanistan, the “Pearson” variety is most popular because of its good commercial value due to its uniform globe shape and medium to large size. The study is conducted to understand the effects of different harvesting stages and postharvest treatments on the shelf life and postharvest quality of tomatoes (Pearson variety) stored under the Pusa Zero Energy Cool Chamber (ZECC) at the research farm of Agriculture Faculty, Kabul University. This is the first time that ZECC is introduced in Afghanistan for enhancing fruit shelf life. The standard dimension ZECC was built with 165 x 115 x 67.6 cm dimensions. After harvesting tomatoes at different maturity stages (Turning, Pink, and Light red color stages), fruits were precooled, graded, and treated with different concentrations of CaCl₂ and mint leaf extract solutions. Thereafter, the tomatoes were placed in plastic baskets and stored in the Zero Energy Cool Chamber. During storage period, Total Soluble Solids (TSS, ⁰brix), pH, firmness (gr cm^-2), shelf life, pericarp thickness (mm), fruit volume (cc), and fruit density were recorded. Two factorial CRD design was considered with harvesting stages as the first factor and postharvest treatments as the second factor. The data revealed that the shelf life of tomatoes was extended up to 29 days under T₂ (turning color fruits treated with 6% CaCl₂) and followed by T₈ (turning color fruits treated with 6% CaCl₂ + 6% mint Leaves extract) up to 28 days. Under T₂, quality parameters such as TSS and pH increased from 3.85%brix and 2.85 to 4.4 ⁰brix and 3.4, respectively. Firmness, pericarp and volume decreased from 1750 grcm^-2, 0.75cm and 135 cc to 840 grcm^-2, 0.67cm and 127 cc, respectively. At the last observation, density remained unchanged (1.00 gr/cc).  In conclusion, tomatoes harvested at the turning-color stage treated with 6% CaCl₂ and followed by 6% CaCl₂ + 6% mint leaves’ extract had a significant effect on the enhancement of shelf life and quality of tomatoes under ZECC condition.

Onion (Allium cepa L.) is among the most cultivated vegetable crops in the world. Afghanistan is thought to be the origin as several local and wild varieties are found in different parts of the country. Safid e Paisaye is a local variety grown in central parts of Afghanistan in the Ghorband valley. This variety has long storability and high market demand among restaurants in the region, but little research has been done to increase the quality and its availability to the market to increase its market share in Afghanistan. Conducted under supervision of Amity University Uttar Pradesh, Noida, India, at Agriculture Faculty Research Farm of Kabul University, this investigation looks at plough depth, land preparation methods, and planting date on quality and yield of onion bulb; it also studied other cultural practices including irrigation and fertilization dose and frequency. The parameters studied in this investigation include neck diameter (cm), bulb diameter (cm), neck to bulb ratio, bulb weight (gr), bulb volume (cm³), bulb density (gr/cm³), Total Soluble Solids (TSS) (Brix), firmness (Kg/cm²), marketable yield (MT/Ha), and total yield (MT/Ha). The data revealed that planting date has significant influence on bulb quality and yield of onion. The highest bulb diameter (6.95 cm), bulb weight (121 gr), bulb volume (128 cm3), marketable yield (32.54 MT/Ha), and total yield (34.24 MT/Ha) and the lowest neck to bulb ratio (0.04) were recorded for the first planting date (seed sown in nursery on 10 March - seedlings planted in field on 10 May). Land preparation methods only had significant influence on marketable yield; the highest marketable yield (26.90 MT/Ha) was recorded for flat bed land preparation method. Plough depth had no significant influence on onion quality and yield. Bulb density, TSS,and firmness were not significantly influenced by factors studied in this investigation. Conclusions: early sowing and planting of onion variety Safid e paisaye can significantly increase yield and productivity. Flat bed land preparation method is more suitable for higher productivity of onion variety Safid e Paisaye as compared to raised beds.
