Cyclic Causation of Conflict and Mental Illness in Selected Tigrigna and Amharic Novels
(Mekelle University, 2025-04-28) Haftu Kahsay Brhanu
This study aims to investigate the cyclic causation of conflict and mental illness in purposively selected Tigrigna and Amharic novels. Specifically, the study was made to identify mental illnesses portrayed in the novels, to show how conflict causes mental illness and vice versa, and to examine the dialectic causal development of internal and external conflicts. It is a qualitative study which employed textual analysis as a method and causal pluralism as a theoretical framework. The causation in conflict is framed by BHN model while the causation in mental illness is framed by BPSS model. The finding shows that unmet basic human needs lead characters to conflict and thereby to various mental illnesses which in turn cause conflicts. It is also found out that intrapersonal, interpersonal and intergroup conflicts result in compromised basic human needs which trigger various mental illnesses. In all the texts under study, family background and relationship is the center of many of the problems that cause the conflicts which lead to mental illnesses like stress, anxiety, conduct disorder, PTSD, narcissistic personality disorder and schizophrenia. Moreover, migration, envy, conspiracy, sexual violence and substance abuse are also found to the major triggers of conflict and mental illness in the texts under study. It is concluded that the ways one perceives himself/herself, understands the family problems, handles conflicts significantly determine the cyclic causation of conflict and mental illness. The study also implies that fictional representation of victim’s life is found to be conducive to portray the cyclic causal relation between conflict and mental illness due to the rich potential of literary works to express the whole person in a plotted manner. The fact that most of the problems that cause conflict and mental illnesses emerge from within the family indicates that a lot is needed to be done to improve the quality of life at family level. All the important aspects of health (biological, psychological, social and spiritual) are strongly related to family relationship. Thus, it is only when a family is changed that changes at communal, societal and national levels could be realized. Finally, I would like to indicate to those who conduct their studies on serious human concerns like conflict and mental illness to utilize the rich potential of literary works like novels so as to address multifaceted problems in a holistic manner. Further studies also need to be done on other genres of literature

Effect of mulching types and varieties on growth, yield and quality of tomato (Solanum lycopersicum L.) in Raya Azebo, southern zone of Tigray
(Mekelle University, 2025-02-01) Tsirha Gidey
Tomato (Solanum lycopersicum L.) is the most significant vegetable crops in the Solanaceae family and one of the most widely consumed fruit vegetables in the world valued for nutritional benefits and economic impacts. However, the cultivation of tomatoes faces various agronomic challenges including low soil fertility, water stress, soil erosion and weed competition, which can adversely affect plant growth and over all yield. The experiment was conducted under irrigation condition from March–July 2024 at Mekelle University, agricultural research and innovation centre Mekoni site, Southern Tigray to evaluate the best mulching types and to screen tomato varieties based on their growth, yield performance and resistance to diseases. It was done in a randomized complete block design with three tomato varieties (Roma VF, Gelilama and Melka shola), three mulching types (white plastic, black plastic, grass) and with as no mulch. Data on plant height, number of primary branches per plant, weed density, soil moisture, disease incidence and severity, fruit diameter, fruit number per plant, total yield per plant, average fruit weight, total yield, marketable yield, unmarketable yield, total soluble solid (TSS) and fruit texture were collected and analysed using GENSTAT, 15th edition. The Duncan’s multiple range test was used to compare between treatment means using a significance level of α = 0.05. The findings showed that strong interactions between mulching types and tomato varieties, while both black and white plastic mulches improved yield and quality parameters. Black plastic mulch appeared the most effective in weed suppression, moisture retention,. In regards to the varieties, Gelilama appeared the most resilient and productive under various mulch conditions, while it may be more prone to disease, its potential for higher economic return due to greater yield fruit quality could make it a viable option for grower, whereas Melka Shola demonstrates high fruit numbers. Based on the current study, white plastic mulch with Gelilama variety is an effective strategy for enhancing tomato yield. However further research on the interaction of drip irrigation with mulching and both breeding and management practices can be conducted to explore its efficiency on tomato production and disease management practices.

THE EFFECT OF IRRIGATION INTERVALS ON GROWTH, YIELD AND YIELD TRAITS OF ONION (Allium cepa L.) VARIETIES IN RAMA ADIARBAETE, TIGRAY, ETHIOPIA
(Mekelle University, 2025-02-01) Kidane Gebresamial Gebrekidan
Onion (Allium cepa L.) is one of the most important vegetable crops in Ethiopia which is used almost daily as a spice and vegetable in the local dish. It is a shallow-rooted crop that requires frequent irrigation to achieve a high yield. Inconsistent or suboptimal irrigation regimes can lead to yield variability among onion varieties. This study was aimed, to investigate the effect of irrigation intervals on the growth and yield traits of onion (Allium cepa L.) varieties and determine optimal irrigation intervals for maximizing crop and water productivity. The experiment was conducted at Rama Adiarbaete, central zone of Tigray, Ethiopia. Split plot design was used to conduct the experiment; by considering four irrigation intervals (5, 8, 11 and 14 days) assigned in the main plot and three onion varieties (Bombay red, Adama red and Red creole) assigned in the sub-plots with three replications. The climatic data of Rama Adiarbaete wereda was taken from Adwa meteorological station. Water requirements of onion were computed using the cropwat model 8.0. The results showed that the onion Bombay red variety irrigated at 5 day interval produces higher marketable bulb yields (12.23 t ha-1), harvest indexes (80%) and water productivity (3.52kg m-3) than Adama red and Red creole. In addition to this, at 8 day irrigation intervals, Bombay red scored the highest harvest index (75.30%), marketable bulb yield (11.05 t ha-1) and water productivity (3.097kg m-3) which was followed by Adama red variety (71.88%, 10.43t ha-1, 2.96kg m-3) respectively. According to the economic analysis, also Bombay red irrigated at 5 days interval resulted in 443% MRR over Bombay red irrigated at 8 days interval and residually ranked first. This could be due to the higher marketable yield of Bombay red when irrigated at 5 days intervals. Therefore, farmers in the study area and similar location should have to use 5 days irrigation interval and use the Bombay red variety when there is accessible labor. However, when there is limited availability of labor in the study area, they have to irrigate the Bombay red variety every 8 days interval for higher productivity and profitability. In case of the scarcity of Bombay red seeds, farmers could use Adama red onion seeds as an option in the study area. The findings should be refined further by taking up multi season data and by measuring soil water characteristics in multi locations.
