In this study three sowing dates (T1 = Mid-January, T2 = Early February and T3 = Mid- February) were tested against three soybean varieties (NARC-I, NARC-II and Rawal) in CRD with four replicates. The results revealed that the effect of sowing dates on seed germination percentage was non-significant (p>0.05) but significant (p<0.05) on rest of the growth, yield and other quality traits of soybean. Similarly, varietal effect on all the growth, yield and its contributing traits were significant (p<0.05). Apart from germination percentage (79.79, 80.33, 81.35 %), significant difference between Mid-January, Early February and Mid-February sowing was determined for plant height (46.89 cm), pods plant-1 (74.79), pod length (4.90 cm), seed weight plant-1 (6.15 g), total biomass weight plant-1(22.91 g), harvest index (26.95 %), number of nodules plant-1 (15.09), root length (8.90 cm), protein content (44.11 %) and oil content (23.64 %), respectively. In case of soybean varieties, NARC- I, NARC-II and Rawal showed significant variation for seed germination (85.35 %), plant height (49.68 cm), pods plant-1(82.07), pod length (5.15 cm), seed weight plant-1 (6.27 g), plant biomass weight plant-1 (23.16 g), harvest index (28.33 %), number of nodules plant-1 (15.87), root length (9.36 cm), protein content (43.36 %) and oil content (23.99 %), respectively. It was concluded that sowing of soybean in first fortnight of February resulted in optimistic results in relation to seed weight plant-1. Too early (Mid-January) or too late (Mid-February) sowing showed similarity (p>0.05) for pods plant-1 and seed weight plant-1. Insignificant (p>0.05) difference between early February and mid- February sowing was observed for pod length, harvest index, nodules plant-1 and root length. On the basis of overall performance, variety NARC-I ranked 1st, NARC-II ranked 2nd and Rawal ranked 3rd; while interactive effect of NARC-II × Early- February sowing maximized seed weight plant-1; while variety Rawal × Early-February sowing resulted in maximum biomass weight. Similarly, interaction of variety ‘NARC-II’ × Mid-February sowing resulted in highest protein content; while interactive effect of variety ‘NARC-II’ × Early-February sowing resulted in highest oil content.","PeriodicalId":497825,"journal":{"name":"Open access journal of agricultural research","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207089","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}

{"title":"The Chloroplast Genome Sequence Characteristics Analysis of Berberis diaphana Maxim","authors":"Ping Li","doi":"10.23880/oajar-16000317","DOIUrl":"https://doi.org/10.23880/oajar-16000317","url":null,"abstract":"Berberis diaphana Maxim (B. diaphana), an important medicinal deciduous shrub, is narrowly endemic to China. In the present study, the complete chloroplast (cp) genome of B. diaphana was sequenced and analyzed. The complete cp genome of B. diaphana is 166, 225 bp in length, presenting a quadripartite structure comprising a large single copy region (LSC 73, 596 bp), a small single copy region (SSC 18, 656 bp), and a pair of inverted repeats regions (IRa/ IRb: 36, 954 bp each). The genomewide GC content was 38.07%, LSC made up 32.59%, SSC made up 32.59%, and IR made up 41.02%. The genome encodes 144 genes, including 99 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. A total of 98 simple sequence repeats (SSRs) was identified. Codon usage analysis showed that the genome tended to use codon ending in A/U. Phylogenetic relationships of 20 species inferred that B. diaphana is sister to Berberis weiningensis. The genome comparison revealed that there is a wide variability of the junction sites, and there is higher divergence in the SSC and IRa/ IRb regions than in LSC regions. This study identified the unique characteristics of the B. diaphana cp genome, which will provide valuable information for further studies as well as molecular identification approaches for this important medicinal plant.","PeriodicalId":497825,"journal":{"name":"Open access journal of agricultural research","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207090","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}

{"title":"Climate-Smart Avocado Farming: A Community-Based Approach to Enhance Adaptation and Resilience","authors":"Simon C Kipchumba Rop","doi":"10.23880/oajar-16000312","DOIUrl":"https://doi.org/10.23880/oajar-16000312","url":null,"abstract":"The purpose of the study was to promote climate-smart avocado farming among smallholder farmers using a community-based multistakeholder platform. Climate-smart avocado farming aims to increase production, and food security, and reduce risks from erratic weather patterns, aligning with sustainable development goals and enhancing agricultural adaptability. Avocado smallholder farmers and other stakeholders formed a multistakeholder platform to address climate-smart practices and adaptation requirements. Data was collected from a random sample of stakeholders using questionnaires. Descriptive statistics and binary logistic regression examined factors motivating farmers to join the platform. A logistic regression model was applied to test the relationship between farmers' expected benefits and participating in multi-stakeholder platform activities. The results indicate that avocado farming activities increased as follows: production, and marketing of improved avocado seedlings (19.2%), market information (18.26%), avocado quality and market promotion (18.92%), access to financial services (19.14%), and capacity building in avocado as a climate-smart practice (16.5%). Farmers' participation in multi-stakeholder planning is related to their anticipated social, material, and economic benefits. Higher levels of social and economic rewards resulted in more participation in the joint planning stage (OR = 1.454). Higher levels of predicted economic rewards increase participation (OR = 1.776). The study revealed that capacity building for integrating avocado as a climate-smart practice positively impacts smallholder avocado farmers' farming systems. For farmers to better adapt to climate change and build resilience, the government, investors, and practitioners are necessary. Modifying policies and programs for climate adaptation is essential. The study supports expanding the multi-stakeholder approach for smallholder farmers in promoting climate-smart agricultural innovation and contributes to enhancing Agricultural Innovation System in rural setup.","PeriodicalId":497825,"journal":{"name":"Open access journal of agricultural research","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207761","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}
