Specifically, the objectives of this study were set out to: examine the socioeconomic characteristics of sampled maize farmers and to evaluate the costs and returns of maize production in the study area. A simple random sampling technique was adopted and used in selecting one hundred fifty (150) maize farmers in the area of study. Data were analyzed using descriptive statistics and gross margin. The study shows that the majority 68.7% were full-time farmers with an average mean of 31 years of age and about 30.96 years of farming experience. The majority (85.3%) were male farmers and only 15.3% of the respondent had no formal education with an average land holding of 1.39 hectares.  The analysis of farm budgetary technique shows and reveals that maize (Zea mays) production in the area of study is a profitable enterprise with a gross margin of ₦72,413.05 and net farm income (NFI) of ₦46,412.25. The coefficient of gross ratio was 0.50; this implies that 50% of the gross income of maize went to offset total farm costs. The net farm income of naira invested was 0.69 and the operating ratio was 0.59. A gross ratio of less than 1 is always desirable for farm business. The study recommends among other things that farmers should strengthen themselves financially by forming cooperative groups whereby members could have access to loans at a very low rate and farm inputs could be purchased in bulk to be shared among members at a reduced.","PeriodicalId":92332,"journal":{"name":"Asian journal of agriculture and food science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43501930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The levels of food security of households in Al-Balqa Governorate were studied. Food consumption score was estimated by frequency of consumption of food group by household within 7 days. Based on answers from the head of household a food insecurity scale was measured. Coping strategies index was valued to be consistent with that of the World Food Programme. Some of factors affecting proportion of expenditure out of total income on food were examined using a multiple linear regression model. The percentage of food expenditure out of total household income, food consumption score, food insecurity scale for each participant, and index of coping strategies with changes related to food deficiency were estimated. Food insecurity scale, age and income of household accounted for 21% of total expenditure. The relationship between food insecurity scale and age and income of households with total expenditure on food had a medium value of 47%. The effect of food insecurity, age, and income was significant on a proportion of total household expenditure on food with negative regression coefficients. The study concluded that households are characterized by an average level of food security, degree of food consumption is acceptable, a measure of food insecurity for each participant is low and marginal, and food security status of household is of second degree.","PeriodicalId":92332,"journal":{"name":"Asian journal of agriculture and food science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42262334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In experiment no. 2, we applied xylazine (2 mg/kg, i.m.) and ketamine (20 mg/kg, i.m.). In experiment no. 3 we used diazepam (1 mg/kg, i.m.), xylazine (2 mg/kg, i.m.) and butorphanol (0.2 mg/kg, i.m.). In experiment no. 4, we administered xylazine (2 mg/kg, i.m.) and butorphanol (0.2 mg/kg, i.m.) to piglets. We applied the mentioned drug combinations intramuscularly in the area of ​​the neck muscles. Subsequently, in each of the experiments, we performed epidural anesthesia using 2% lidocaine, in a dose of 1 ml/40 cm of body length.\u0000After putting the animals under anesthesia, we recorded breathing and pulse frequencies, body temperature and checked reflex responses at time intervals. We performed a zero blood collection before the application of the first drug, the first collection after anesthesia and then a second collection the next day, in order to determine the hematological profile. From the conducted experiments, we assessed the relationship of the used combinations of substances to the course and depth of anesthesia and, according to the hematological profile, we evaluated the effect of these substances on specific hematological parameters.\u0000We recorded the longest duration of anesthesia in the first experiment when one of the piglets had disappeared pedal reflexes even after 90 minutes. On the contrary, the shortest anesthesia was during the third experiment, when all piglets reacted 60 minutes post-lidocaine. During experiments 1 and 3, we noticed a significant drop in body temperature compared to the reference values. In a short time interval after the lidocaine administration, the reflex of the pelvic limbs completely disappeared in all tested subjects in each of the experiments.  In experiment no. 3, at time 5 minutes post lidocaine administration, the nasal reflex and the reflex of the forelegs were also negative in all animals. In all tested subjects, 30 minutes after the epidural anesthesia was performed, we observed a negative reflex of the pelvic legs during the second and third trials.

The postproduction losses using different models of RCH were established following a randomized complete block design with two replications and these were compared with the traditional method of harvesting and threshing rice. Partial budget analysis was employed to determine the benefits derived by farmer-adopters using the data gathered from a one-shot cross sectional survey involving 448 respondents. Results of the field experiments revealed that postproduction losses with the three models of RCH did not differ significantly, ranging from 1.19% to 1.76% of the total yield.  Comparing the harvesting-threshing losses in using RCH and the traditional method, the use of RCH significantly reduced harvesting-threshing losses by 1.02 percentage points. Prevention of postharvest loss was more pronounced during the wet season harvest at 1.54 percent. From the point of view of the farmer-adopters, the use of RCH lowered harvesting costs by PhP 3,908.60/ha/ and gained additional PhP 718.40/ha for losses prevented by using RCH. Thus the farmer-adopter could potentially gains additional benefit of PhP 4,627.00/ha/cropping season. With these, the use of RCH has the potential to enhance rice competitiveness by lowering the production cost and preventing paddy loss by PhP1.12/kg or 9.56% of the current production cost. ","PeriodicalId":92332,"journal":{"name":"Asian journal of agriculture and food science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42796726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
