Accordingly, a field experiment was carried out in Salinity Management and Research Center, Soil Resource Development Institute, Batiaghata, Khulna during Kharif-1 season of 2021 to investigate the effect of different types of mulches on soil salinity and yield of pumpkin. The experiment includes three treatments viz. no mulch (control), straw mulch and mulching paper. The experiment was carried out in Randomized Complete Block Design with four replications. Soil salinity was recorded at 30 days intervals. All mulching materials effectively reduced the salt accumulation in the root zone. After three months of seed sowing, the highest soil salinity (11.32 dS/m) and lowest soil salinity (6.24 dS/m) were found at no mulch (control) and mulching paper treatment respectively in the month of May. Mulching treatments markedly increased the growth and yield attributes of pumpkins. The highest value of three growth parameters i.e., fruit length (26.92 cm), fruit diameter (94.09 cm) and fruit size (2037 cm2) was found on mulching paper as compared to control. Again, the highest flesh thickness (3.94 cm), fruit weight (4.73 kg) and yield (31.18 t/ha) were recorded at mulching paper treatment whereas the lowest yield (16.68 t/ha) was found at no mulch (control). The results revealed that the use of mulching paper decreased salinity and also increased the yield of pumpkin in saline soil. These findings suggest that the application of mulching paper not only reduces soil salinity but also increases the yield of pumpkins.","PeriodicalId":298912,"journal":{"name":"Asian Journal of Agricultural and Horticultural Research","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127179739","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}

Additionally, efforts were undertaken to identify the challenges marginal farmers faced in attaining household food safety. Due to this, the study was carried out in three randomly chosen villages in the Rajbari district's Baliakandhi upazila. In these three communities, out of 500 marginal farmers, 26% of the populace was randomly selected. Data was acquired through direct interviews with marginal farmers between January 5 and February 20, 2009. The majority of marginal farmers (51%) fell into the medium group in terms of the contribution of farming enterprises to domestic food safety, while 37% fell into the low category. More over half of the family's food requirements were still unmet by the farming operations, which only met 40% of them annually. The biggest percentage of age (42%) of the four farming enterprise categories came from crops alone. Among the ten traits of the marginal peasants, the size of the farm and the yearly family income were positively connected, whereas the size of the family, the annual nutritional demands of the family, and cropping intensity practiced were negatively correlated. The remaining traits were not significantly correlated with how much farming operations contributed to household food security. Lack of suitable land for farming, poor training facilities, and ignorance of various facets of better farming enterprises were the main challenges marginal farmers faced in achieving household food security.","PeriodicalId":298912,"journal":{"name":"Asian Journal of Agricultural and Horticultural Research","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133852889","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}

Scores from the pre-and post-tests for the pupils were submitted to a quasi-experimental design. While the students in the control group were taught the same concepts using the traditional method, the students in the experimental group learned agricultural concepts through computer-assisted instruction (CAI). The traditional mode of instruction included lectures, group discussions, and question and answer sessions. The study's results demonstrated that pre-service teachers who received CAI performed better than their counterparts who received traditional classroom teaching.

However, information on farmer’s knowledge about tomato diseases to warrant pesticide usage is scanty. Further, there is information gap on disease predisposing factor such as varietal choice and seed source. This study assessed the tomato farmers’ socio characteristic, varieties grown, seed source and knowledge of selected foliar fungal disease among tomato farmers in agro-ecological zones (AEZs) of Kirinyaga County. A cross sectional survey design that in cooperated purposive sampling and snowballing approaches was adopted in the study. Data were collected from 120 tomato farmers using structured questionnaires. A chi square (Ӽ2) test was used to examine the association between different variables at α= 0.05 using SAS version 9.4. No significant association (p > 0.05) was observed between gender of farmers and AEZ. Nonetheless, there were more men (83.33%) than women (16.67%). Terminator F1 variety was popular among farmers (25%). No significance (p > 0.05) association was observed between source of tomato planting material and AEZs. However, Agrovet was a popular seed source among farmers (40%). The reasons for choosing a particular tomato variety was significantly (p < 0.05) associated with the AEZ with 40.83% of farmers preferring tomato varieties with good marketability traits such as fruit size. Farmers’ knowledge of causative agent of early blight, late blight and Septoria leaf spot was significantly (p < 0.05) associated with AEZs. The source of farmer’s knowledge on tomato foliar fungal diseases was not significantly (p > 0.05) associated with AEZ. However, farming experiences was a popular source of knowledge (51.67%) among farmers. Inability of some farmers to identify tomato diseases negates the efforts on disease management in tomato production in Kirinyaga County. Therefore, measures such as coordinated education on tomato diseases is necessary to empower farmers on disease causes and identification to enhance disease management and improve tomato yields in Kirinyaga County in Kenya.","PeriodicalId":298912,"journal":{"name":"Asian Journal of Agricultural and Horticultural Research","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121274209","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}

Nwankwo","doi":"10.9734/ajahr/2022/v9i430157","DOIUrl":"https://doi.org/10.9734/ajahr/2022/v9i430157","url":null,"abstract":"Physic nut (Jatropha curcas) is a bio-fuel and multipurpose crop that can be used to produce biodiesel, biogas and latex. The toxic substances – curcin and diterpenoids in raw Jatropha leaves and seeds can scare grazing animals away and this suggests the possibility of using the plant as live fence to curb cattle menace which is one of the major constraints facing crop production in Sub-Saharan Africa especially in Nigeria. Despite its nutritive, medicinal and economic values, Jatropha is one of the most neglected crops in Nigeria and in sub-Sahara Africa at large. There is often loss of vigour of Jatropha seedlings due to high seed oil content which results in rancidity and weak seedling growth. An experiment was conducted at Enugu State Polytechnic, Iwollo, Enugu state, Nigeria to determine the appropriate nursery media towards improving the production of Jatropha curcas in sub-Saharan Africa. Four nursery media viz: 3:2:1; 1:2:1; 0:0:1 and; 1:0:0 of top soil, organic manure and river sand respectively, were evaluated. The experiment was laid out in Completely Randomized Design (CRD) with three replications. Data on emergence percentage, seedling height, number of leaves per seedling and seedling girth were collected and analyzed using Analysis of variance (ANOVA) for CRD. The treatment means with significant differences were separated using least significant difference at 0.05 probability level. The results showed that there was no significant difference (p>0.05) among the treatments in emergence percentage of Jatropha curcas. However, there were significant differences (p<0.05) among the treatments in seedling height and stem girth with the highest values obtained in 1:2:1 of top soil, poultry droppings and river sand, respectively and the least in 0:0:1 of top soil, poultry droppings and river sand, respectively. It could be concluded that the use of 1:2:1 of top soil, organic manure and river sand, respectively significantly improved seedling growth of Jatropha curcas compared to the other treatments and could therefore be recommended for Jatropha curcas nursery for improved production of the crop in sub-Sahara Africa.","PeriodicalId":298912,"journal":{"name":"Asian Journal of Agricultural and Horticultural Research","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131416437","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}
