Abstract

A study to Evaluate the performance of different varieties of potato was conducted in Daulichaur, Bajhang from February to June, 2021. Six commonly grown potato varieties namely Cardinal, Janakdev, Khumal rato-2, Khumal Ujjwol, MS 42.3 and Bajhang local were used for the study. An experiment was conducted in Randomized Complete Block Design (RCBD) with 6 treatments replicating 4 times each. The data on plant height, number of main stems per hill, number of leaves, and canopy diameter were taken at different days after planting (DAP) and the data on number and weight of tubers were taken after harvesting of potato. Data entry and analysis was done in MS-Excel and R-Studio. Significant variation among the varieties in terms of plant height, main stem per hill, canopy diameter and leaves number per plant was observed. Number of stems per hill was found maximum (3.88) and minimum (1.63) on Bajhang local and Janakdev respectively. Plant height is found maximum on Janakdev (42.75 cm) and minimum on Khumal rato-2 (21.45 cm). The maximum (40.90) and minimum (27.55) number of leaves per plant was recorded on Khumal Ujjwol and Cardinal while maximum and minimum canopy diameter was observed on Bajhang local (40.90 cm) and Khumal rato-2 (36.12 cm). Similarly, yield and all the yield attributing parameters was found significant at 5% level of significance. Highest number of tuber per plant was observed on Bajhang local (17.25) and lowest number of tuber per plant was observed on Khumal rato-2 (8.25) in which highest number of marketable size tuber per plant (>25g) was recorded on Khumal Ujjwol (12.05) and lowest number of marketable size tuber per plant (<25g) was recorded on Khumal rato-2 (5.75) but variation among the varieties in case of unmarketable tuber per plant was non-significant. Highest tuber weight per plant (485.50g) and lowest tuber weight per plant (306.25g) was recorded from Khumal Ujjwol and MS 42.3 respectively. The highest tuber yield was recorded from Khumal Ujjwol (40.45 t/ha) and lowest from MS 42.3 (25.52 t/ha).

Abstract

Human intestinal parasites are among the most common infectious diseases worldwide. This study was conducted to determine intestinal parasites prevalence and risk factors in the study area. A total of 350 consented inmates aged 18->60 years participated in the study. Stool samples were screened using wet preparation and formol ether concentration method. An overall prevalence of 48.8% was recorded for intestinal parasite, which was significantly (p< 0.05) high among females. Five species of intestinal parasite were identified. The most common identified was hookworm (95, 33.5%), while the least was Trichuris trichiuria (33, 11.6%). Age group 51-60 years recorded the highest infection (63.33%) among the males, while age group 18-20 years had the least (25.0%). Age groups 51-60 and >60 years recorded 100% infections among the females. Of the 171 infections recorded, 97(56.7%) had single infection, while 74(43.3%) had multiple infections. Questionnaire analysis showed that inmates who have been in the prison for years were more parasitized. Inmates who deworm monthly, yearly and not at all accounted for 64.2%, 78.7% and 39.2% infections respectively which was significant (p< 0.05). The study revealed the prevalence of intestinal parasitic infections in the inmates. Improved healthcare and awareness is highly recommended inside the facility.

Abstract

The efficacy of the plant powder of Alchornea cordifolia was evaluated under laboratory conditions against the larvae of the leather beetle Dermestes maculatus which is a major fish pest that cause serious damage when left uncontrolled. The experiment was in concentrations of 0g, 1.0g, 2.0g, 2.5g, 3.0g admixed with 15g of smoked fish powder; while all the treatment containing 0g were without plant powder which served as control, all the treatment were in triplicates. Newly emerged (0 - 72 hours old) larvae of D. maculatus were introduced. Evaluation of the potency of the plant powder was based on larvae mortality and the adult emergence. The weight losses in fish muscle in the treated and untreated samples were compared as index of fish damage during storage. The result showed that higher plant powder concentration were significantly (P<0.05) effective in killing larvae stage of the insect as well as the larvae at 1st and 2nd weeks after infestation (WAI). Adult emergence was significantly (P<0.05) inhibited in the treated fish and weight loss due to insect infestation was greatly suppressed by the higher dosage rate of the plant powder compared to control. The findings showed that efficiency of A. cordifolia leaf powder is dosage dependent and is capable of controlling the larval stage of D. maculatus in smoked fish (Clarias gariepinus) during storage. It is therefore recommended that plant could be used by poor resource fish farmers, processors and marketers in protecting smoked-dried fish against D. maculatus during processing, transportation, marketing and storage.

Abstract

Some important information on the population biology and stock assessment of African moony fish (Monodactylus sebae) was scrutinized based on monthly length frequency data collected from New Calabar River, Nigeria from February 2020 to March 2021. The estimated von Bertalanffy growth parameters were growth performance index 2.91 per year, asymptotic length (L∞) and growth curvature (K) were 36.54 cm and 0.61yr-1 respectively. The estimated theoretical age at birth (to) and longevity for the assessed fish species were 0.55 years and 2.91 years, respectively. The total mortality (Z), natural mortality (M), fishing mortality (F), for M. sebae were 1.87 year-1, 1.23 year-1  and 0.64 0.64 year-1 respectively. The length at first capture (Lc) was 8.56cm. The exploitation rate (E) and maximum exploitation rate (Emax) were calculated as 0.34 and 0.36 respectively. The recruitment pattern occurs throughout the year, with only one recruitment peaks in May with 19.9 % recruits. Biological reference points: Emsy which depicts exploitation rate producing maximum yield of a cohort indicated that, the exploitation rate which maximizes yield per recruit produced values of Emax was 0.36 while E50 was 0.23 for M. sebae indicates that the current exploitation rate was below the maximum sustainable yield, indicating that this stock was underexploited

Abstract

Abstract Over the years, the use of agrochemicals has been one of the reasons for resistance of mosquitoes to insecticides, a negative trend that has been on the increase. This study was carried out to determine the effect of Azadirachta indica (neem) seed extract on the larvae and adult Anopheles mosquitoes in Nasarawa Local Government Area of Nasarawa state as a possible alternative to already existing insecticide against the parasite. The research was carried out at the insectary laboratory of Nasarawa state university Keffi. Impregnated papers of neem seed oil were used for adult Anopheles mosquitoes and the larviciding effect was also determined. Adult Anopheles mosquitoes exposed to impregnated papers of neem seed extract at different concentrations of 20%, 40%, 80% and 100% showed 5%, 29%, 66% and 91% respectively. Mortality rate was recorded at 24h of exposure with LC50 (Lethal concentration) of 4.45ml. The larvae were also exposed to different concentration of neem seed extract of 1%, 4%, 8% and 10% for 72h and the mortality rate was 100% with LC50 value (Lethal concentration) of 4.16ml. This implied that adult Anopheles mosquitoes will required more of the extract to achieve 100% mortality than larvae. Using Azadirachta indica (neem) seed extract as an anti-mosquito agent was more effective on the larvae of Anopheles mosquitoes than the adult Anopheles mosquitoes.

Abstract

Biochar is a thermal decomposition product known to mitigate climate change and a supplement to enhance soil fertility. The fine-grained, highly porous structure of biochar makes it a popular choice in environmental research. This study aims to assess the Physico-chemical properties and morphological changes in the biochar prepared from feedstocks: sawdust, sugarcane bagasse, and soapnut pith of Sapindus trifoliatus, native to the foothills of Western Ghats, Kerala, at a temperature of 300 oC and 600oC with 30 minutes residence time. The pyrolytic temperature and feedstock type may affect the yield, ash content, volatile matter (VM), fixed carbon (FC), and nutrient composition of biochar. The selection of these two factors is critical before proceeding with charring. The efficiency of biochar was determined through proximate, ultimate, and morphological characterizations. The pH of high-temperature biochar (sawdust biochar, sugarcane bagasse biochar, and soapnut pith biochar prepared at 600oC) was more alkaline (≥7) compared with low-temperature ones. The char yield was highest at 300oC, whereas the fixed carbon was limited. The VM/FC ratio of SDB600 at 1.09±2.3 represents the highest aromaticity and long-term stability. Therefore, SDB600 can be recommended for soil supplementation purposes. The macrospores were uniformly distributed throughout the biochar surface. Sugarcane bagasse pyrolyzed at 600oC (SBB600) possessed the minimum pore diameter (0.87-9.17µm), with the highest surface area; so that it could be an optimum habitat for soil microbiota as well as a suitable adsorbent for environmental remediation applications. The study suggests that biochar made from these ligno-cellulosic feedstocks is a sustainable tool and a value-added product for environmental management.

Abstract

Grouper is one of the demersal fish groups that are abundant in Indonesian marine waters. In addition, the high market demand for this fish has also increased its main production technique as an export product. One example of a product from this fish is fish fillet which still leaves waste. Offal is an example of a by-product of grouper which is underutilized so that it is of low value in the market and as a resource. The high protein content of fish offal can be used as a raw material in the manufacture of protein hydrolysates which of course require the role of proteolytic enzymes. Bromelain enzyme which is a proteolytic enzyme that is protease. This study aims to determine the effect of the bromelain enzyme concentration obtained from pineapple crude extract on the quality of the protein hydrolyzate of grouper offal. The experimental design used in this study was a Factorial complete randomized design with different enzyme concentrations (4, 6, 8, 10). and 12%) and the difference in water bath time (4, 6, 8, and 10 hours). The results showed the bromelain enzyme concentration had a very significant effect on the yield and degree of hydrolysis of snapper offal, and observations of the proximate results showed the potential utilization of hydrolyzed protein of fish offal as a food source.
