To increase the productivity of the crop and support farmers, the development of yield and disease-resistant varieties is an important activity. Thus, the purpose of this study was to examine genetic variability and associated agronomic traits among field pea genotypes. A total of 49 field pea genotypes were evaluated at Bekoji in 2020 using a simple lattice design. Analyses of variance were performed on the morpho-agronomic data collected. Most traits were significantly different among genotypes, except pod per plant, pod length, and seed per pod. Variations in genotypes for grain yield ranged from 412 to 4498 kg ha-1. EH 010011-3, EH 05048-5, and EK 08017-3 were the genotypes with the most yield advantage over Bursa (3714.0 kg ha -1), with yield advantages of 21.11, 1.13, and 1.19%, respectively, over the highest yielding check variety. Genotype EH 010011-3 showed the highest mean grain yield of 4498 kg/ha. Phenotypic coefficients of variation ranged from 2.33% for days to maturity to 29.40% for thousand seed weights, whereas genotypic coefficients of variation ranged from 2.20% to 24.31% for days to maturity. In general, the estimated broad sense heritability ranged from 63.85% for harvest index to 89.21% for days to maturity. The genetic advance as a percentage of mean ranged from 4.28% for days to maturity to 42.16% for grain yield. The study showed that field pea genotypes exhibit reasonable genetic variation, which could be used to develop breeding programs.","PeriodicalId":415976,"journal":{"name":"Asian Journal of Research in Crop Science","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115312881","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}

Ralstonia solanacearum causes a devastating bacterial wilt that is wide-spread throughout tropical environments that has been difficult to control with chemicals and African cultural practices in poor regions of the world. This study was initiated to determine the inhibitory effect of methanolic root extract of Senna didymobotrya and Moringa oleifera seed extracts on growth and development of R. solanacearum. The study was conducted both in the Laboratory and in the green house in Maseno from where S. didymobotrya and M. oleifera specimens used were collected from the University Botanic Garden, dried under shade for 30 days, before being ground into a fine powder. 1000 grams of the plant powder was later transferred into a conical flask and covered with 250mls of methanol. Filtration was done and the extracts concentrated. Ten diseased tomato plants showing bacterial wilt symptoms earlier collected from Maseno, Mariwa, Seme and Holo all within Kisumu county (Kenya) were cut to obtain plant sections (0.5–1cm) that were later plated onto Triphenyltetrazolium chloride media. Bacteriostatic activity of the extracts was determined by the disc diffusion method on Mueller Hinton agar. In vivo evaluations were conducted in a green house using tomato seedlings. Data collected was subjected to analysis of variance and means separated were compared using least significance difference (P≤ 0.05). Both plants extracts showed inhibitory activity against R. solanacearum pathogen (M. Oleifera; 8.5 and S. didymobotrya 9.2). Based on the outcome of this study, S. didymobotrya is recommended as a potential botanical agent suitable for future trials and use in the control of R. solanacerum by tomato farmers in Maseno region Kisumu county.","PeriodicalId":415976,"journal":{"name":"Asian Journal of Research in Crop Science","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116121355","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}

Fourteen field pea (Pisum sativum L.) advanced genotypes were evaluated at Arsi zone for two years (2014-2015) main cropping season across eight environments using randomized complete block design with four replications. There was a significant difference (P<0.001) in grain yield based on genotype, year, location, and the interaction of (G x L, Y x G). In this study, genotypes responded differently to different environments and at different times of the year. There was a range between 3509 kg/ha (G6) and 2809.5 kg/ha (G12) for the highest and the lowest mean grain yields. According to the mean and stability view of the GGE biplot, G6 followed by G1 was the most productive genotype in all environments except E5 and E6, while G5, G12, and G9 were the least productive. Based on the polygon view, five sectors were formed, and genotypes G13, G8, G6, G3, and G5 won. The G6 was an ideal choice in terms of mean yield and stability (high mean yield and adaptable). It was considered desirable to have genotypes G1, G4, and G3 closest to an ideal genotype. In most environments, G6 is a more adaptable genotype than any other genotype, making it a more suitable genotype for commercial production.","PeriodicalId":415976,"journal":{"name":"Asian Journal of Research in Crop Science","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128706144","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 objectives of this study were therefore, to; i) assess the effectiveness of push-pull technologies in controlling Spodoptera frugiperda infestation in maize ii) cluster the technologies into distinct sets, and iii) identify the variables with high discriminating influence among clustered push-pull technology sets. \u0000Place and Duration of Study: The research was undertaken in Chilanga district, Zambia during the 2021/ 22 cropping season. \u0000Methodology: The experiment was laid as a randomised complete block design (RCBD) with three replications and 6 treatments. Four push –pull combinations and the two controls (Negative and Positive). Maize was used as a test crop. Data on Spodoptera frugiperda incidence was collected at weekly intervals for a period of 5 weeks and at harvest from maize crop. Analysis on measured variables was computed using analysis of variance (ANOVA) and principle component analysis (PCA), a multivariate tool. \u0000Results: Significant differences were obtained on all measured variables except harvest index with regards to push- pull treatments main effects (P =0.05). The evaluation of treatments using principal component analysis showed that push - pull treatments clustered into four sets, arising from a phenotypic variation explained of 89.1%. \u0000Conclusion: This study revealed Pearl millet/ Marigold push-pull treatment as the best performing treatment with a mean maize test yield value of 7.2 tons per hectare. For variables: number of damaged leaves, injury score leaves, egg batch, biomass with cobs, shelling %, plant height and grain yield were identified as important at differentiating the performance of push pull technologies.","PeriodicalId":415976,"journal":{"name":"Asian Journal of Research in Crop Science","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122415890","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}
