Sim-Sim (Sesamum Indicum L.) bio-Ash efficacy determination on tomato (Solanum Lycopersicum) shelf life in Central Uganda
Nankuta, Dorothy; Murongo, Marius Fabian; Kalanzi, Keefa; Tumwizere, Collins
Introduction - Tomato (Lycopersicon solanum) is a vegetable crop which belongs to a family Solanaceae and is dicotyledonous
plant.Despite its nutritional, economic, and health value, tomato production is hampered by post-harvest losses,
which limit the longevity of storage and the number of high-quality products available to customers. This study
investigated the effect of sim-sim (Sesamum indicum L.) bio-ash efficacy determination on tomato (Solanum
lycopersicum) shelf life in central Uganda. The specific objectives of the study were: to determine the effect of
different rates of sim-sim ash on decay incidence and weight loss of tomatoes stored at room temperature, to
assess the effect of sim-sim ash and their effect on textural characteristics (hardness, softness soggy and spoilt) of
tomatoes stored at room temperature and to examine the effect of different rates of sim-sim ash on the sensory
attributes (half ripe and full ripe) for the tomatoes stored at room temperature. An experiment was conducted at
the Faculty of Agriculture of Uganda Martyrs University in Nkozi Sub County, Mpigi district during the months of
March-July 2022 cropping season. A
Methodology - An experimental design used was completely randomized design (CRD) in the study with four treatments. The
factors studied included 0.5kg (P2), 1.0kg (P3) and 1.5kg (P4) of sim-sim bio-ash and control (P1) in which tomatoes
were stored for a period of 55 days. Different parameters were assessed, decay incidence, weight loss, hardness,
softness, sogginess of tomatoes and number of spoilt tomatoes, half ripe and full ripe tomatoes .Data collected
was subjected to statistical technique of analysis of variance (ANOVA) at (P<0.05) to ascertain the Fishers
probability (Fpr), grand mean, Least signifi-cance differences (L.S.D and percentage co-efficient of variations (%
CV). Means were compared using the least significance difference best (L.S.D) and was analysed using Genstat a
statistical package version 14.
Results & Discussion - The results of the study indicated that there were highly significant differences (P<0.001) recorded with the
different rates of sim-sim bio ash on decay and weight loss of tomatoes, The results indicated that 1,5kg of sim
sim ash gave the lowest percentage decay of 79% and lowest weight loss. Further the results revealed that 1.5kg
of sim sim ash gave the lowest number of soft, soggy and spoilt tomatoes but with the highest number of hard
tomatoes. Finally 1.5kg of sim sim ash gave the highest number of full ripe tomatoes and lowest number of half
ripe tomatoes during the storage period.
Conclusion - Basing on the results of the study ,It was also concluded that storing tomatoes in 1.5kg of sim-sim ash
gave the lowest percentage decay and weight loss, increased number of hard tomatoes and reduced number of
soft, soggy, spoilt tomatoes as well as increasing tomato ripening faster than the other counter parts
treatments. Therefore farmers are recommended to store tomatoes in 1.5kg of sim-sim ash.

Introduction - The cultivated tomato, (Solanum lycopersicum L.) is the world’s most highly consumed vegetable due to its status as
a basic ingredient in a large variety of raw (Wu et al., 2022), cooked or processed foods. It belongs to the family
Solanaceae, (Lima et al., 2022) which includes several other commercially important species. Tomato is grown
worldwide for local use or as an export crop. In 2014, the global area cultivated with tomato was 5 million
hectares with a production of 171 million tons (Camara et al., 2022), the major tomato-producing countries
being the People’s Republic of China (hereafter “China”) and India (FAOSTAT, 2017). Tomatoes can be grown in a
variety of geographical zones in open fields or greenhouses, and the fruit can be harvested by manual or
mechanical means (Masetti et al., 2020).
Methodology - he researcher used a Completely Randomized Block Design which was a plan, strategy and investigation
structure in a certain element, so this was used as a tool for obtaining the answers to research questions and
problems. This was used in obtaining an operational plan in executing a few required steps for completing the
research and ensures that the chosen research design was as sufficient and adequate as possible for seeking the
authentic findings, answering the objective of the study and pointing sharply on research questions. The
treatment which was replicated into three different quantities; this treatment was eucalyptus ash under
measurements of 0.5g, 1g and 1.5g and the control where no ash was added to the tomatoes.
Results & Discussion - Analysis of variance showed that different quantities of eucalyptus ash based storage media significantly
(P<0.05) influenced decay percentage in stored tomatoes (Table 2 and Figure 4). The results indicated that the
first two weeks of storage and data collection, tomatoes stored in the different eucalyptus ash based storage
media showed no significant differences (P<0.00) in decay percentage. The results also indicated that the
different eucalyptus ash based storage media and control gave the same decay percentage of 0.00% in week
one and week two. This could be attributed to the fact that in the first two weeks, tomatoes had not fully under
gone physiological changes which can lead to rotting. On another hand, in the first two weeks of storage,
tomatoes had not yet started losing water to the surrounding which could favor microbial attack. The results
indicated that tomatoes stored in 1.5kg of eucalyptus ash gave the lowest significant (P<0.00 and <0.003) decay
percentage of 7% and 79% in week three and eleven of data collection respectively. The results further indicated
that there were no significant differences in same weeks among tomatoes stored in1.5kg of eucalyptus ash for
instance in week three and four which gave a decay percentage of
Conclusion - It was concluded that 1.5 kg of eucalyptus ash gave the lowest decay of tomatoes, this further gave the lowest
weight loss and also the lowest level of softness of the tomatoes.

Introduction - Cooked bananas, also known as matooke, are the main source of food in Uganda’s Central, Western, and Mt.
Elgon regions. Recently, the production of bananas has been seriously threatened by numerous pests and
illnesses. Nematodes and banana weevils are major pests, and bacterial infections and panama wilt are the most
common diseases. There hasn’t been sufficient research that address women’s engagement in the usage of
biorationals in the study area. A study that was conducted in the Central Ugandan districts of Masaka and Mpigi
assessed the extent to which women used biorationals to treat pests and diseases that affects bananas, as well
as farmers’ assessments of how efficient these treatments were.
Methodology - Using both quantitative and qualitative data, social economic approaches were applied. A structure
questionnaire and key informant interviews were used. A logistic model was used to determine the farmers’
perceptions of the effectiveness of biorationals in getting rid of banana weevils. The survey’s sample size was 144
house-holds, or one hundred forty-four. Organic farmers were identified using snow ball sampling, while the
remain-ing farmers were chosen using a random sampling technique. The sample was chosen using an
undisclosed population sampling method
Results & Discussion - According to the logistic model, women were more likely than men to consider biorationals to be effective.
Knowledge (awareness) of the product played a key role in farmers’ perception of and use of biorationals goods.
Farmers with a secondary education embraced and evaluated the usage of biorationals as being extremely
important
Conclusion - According to this approach, women’s participation, farmers’ training in banana production, and the usage of
livestock products are all crucial issues that need to be addressed in order to increase the use of biorationals in
banana production.

Introduction - This study compared the efficacy of sisal (Agave sisalana) and sweet thorn (Acacia karroo)ethno-medicinal extracts
on prevalence of selected pests and diseases in Assila F1 tomato variety was carried out in order to provide
cheap and safe alternative in controlling tomato pests and diseases.
Methodology - A 13x13m complete randomized block design with nine replicates was used to determine the prevalence of tomato
pests and diseases. The assessment was done at organic demonstration site of Uganda martyrs university using
three treatments; sisal extracts, sweet thorn extracts and control. Healthy tender leaves of sisal and sweet thorn
were harvested and 10kgs of each treatment were measured and chopped into small piece, crushed then 5litres
water was added. The prepared mixtures were then shaken and sprayed uniformly onto the tomato plants in the
plots to which they were assigned to at a 4 days interval starting from one to eight weeks 8interval after
transplanting for 8 times. Meanwhile control plants were not sprayed. Each replicate had 20 plants and 10 plants
were selected for data collection in each replicate. Agronomic traits were evaluated by measuring plant height,
stem girth,leaf length,leaf width, leaf length using ametre rule. Final fruit yield was measured by weighing mature
tomatoestomatoes. Pests were assessed as follows; whiteflies were assessed by counting the adult white flies.
Aphids were assessed using a pest scoring scale of 0-5;African bollow worm is assessed using a scoring scale of
1-5. Disease severity was assessed as below; early blight and late blight severity was assessed using ascale of
1-4 .Bacterial spot severity was scored using the scale of 1-6 and then powdery mildew severity was estimated
using a disease scoring scale of 0-5. The analysis of variance (ANOVA) at(P<0.05) was carried and means were
compared using LSD.
Results & Discussion - The results of the study indicated thet there was significant (P<0.05)diferences recorded between sisal and sweet
thorn ethno medicinal extracts for pest prevalence. The lower mean for white flies (0.78), tomato fruit borer (1.3)
and aphids (0.86) and red spider mites(0.3) prevalenece score were recorded for sisal ethno medicinal extracts
than sweet thorn extracts but lower than the control plots. There was significant differences (P<0.05) observed
between of application of sisal and sweet thorn ethno medicinal extracts for disease prevalence. The lower mean
for early blight (1.1), late blight (1.6), bacterial spot (1.1)and powedery mildew severity (1.8) severity scores were
recorded for sweet thorn ethno-medicinal extracts than sisal extracts but lower than the control plots. The results
of the study revealed that application of sisal extracts significantly (P<0.05) increased plant height, stem girth, leaf
length, leaf width and final fruit yield. Application of sisal and sweet thorn ethno- medicinal extracts significantly
(P<0.05) showed an effect on the yield components and yield of tomatoes. The higher final
