Objectif : La présente étude vise à une meilleure connaissance du niébé vert par l’évaluation des performances agronomiques de douze (12) variétés. Méthodologie et résultats : Les variétés ont été évaluées par douze (12) variables quantitatives dans un dispositif en bloc de Fisher avec trois (3) répétitions à l’INERA/Kamboinsé en 2018. L’étude a montré l’existence d’une grande variabilité agronomique au sein des variétés étudiées. Des corrélations positives et significatives ont été aussi observées entre les variables. L’Analyse en Composante Principale (ACP) des variables a permis d’identifier la date 50% floraison, le SPAD, la date niébé vert, la date 95% maturité, le nombre de graines par gousse, le poids gousses, le poids graines, le poids fanes, le rendement graines et fanes comme les paramètres les plus pertinents qui discriminent les variétés. La meilleure variété a été le niébé baguette grimpant qui possédait une date niébé vert (50 jours) et une maturité (63 jours) précoce. Conclusion et application des résultats : La variété IT83S-872 a été identifiée comme très productive en termes de gousses (77 gousses). La variété Komsaré a obtenu un rendement en graines (2,72 t/ha) et en fanes (3,20 t/ha) très appréciables. Cependant, la variété IT85F-2887 s’est montrée exceptionnelle, car en plus d’avoir une date de niébé (50 jours) vert et une maturité précoce (65 jours), elle a présenté un bon rendement en graines (2,63 t/ha) et le meilleur rendement en fanes (3,67 t/ha). Ces variétés précoces, productives en graines et en fourrage pourront être des substituts du haricot vert et contribuer efficacement à l’amélioration de la production du niébé au Burkina Faso.

Methodology and results: The varieties were evaluated in a randomized complete block design (RCBD) with three (03) replications using 12 quantitative variables at the Kamboinsé research station 2018. The study revealed the existence of important agronomic variability within the studied varieties. Positive and significant correlations were also observed between variables. Principal Component Analysis (PCA) identified days to 50% flowering; the chlorophyll content (SPAD); days to vegetable cowpea; days to 95% maturity; number of seeds per pod, pods weight, seeds weight, fodder weight, seeds yield and fodder yield as the most relevant parameters. The best variety was niébé baguette grimpant, with the earliest days to vegetable cowpea (50 days) and days to maturity (63 days). Conclusion and application of results: The variety IT83S-872 has been identified as the highest pods productive (77 pods). The variety Komsare recorded a very appreciable seeds (2.72 t/ha) and fodder (3.20 t/ha) yield. However, the variety IT85F-2887 was exceptional, in addition to its earliness for days to vegetable cowpea (50 days) and days to maturity (65 days), it recorded the best seeds (2.63 t/ha) and fodder (3.67 t/ha) yields. These early maturing, high seeds and fodder producing varieties, could substitute common beans and effectively contribute to the improvement of cowpea production in Burkina Faso. Key words: Vegetable cowpea, agronomic performance, fodder, Burkina Faso.

Yard long bean (Vigna unguiculata var. sesquipedalis L.) is one of the important leguminous vegetables in Bangladesh. However, yield of this vegetable is much lower in Bangladesh compared to other yard long beangrowing countries. Therefore, it is crucial to improve the yield of this vegetable. In the present study, genetic variability, heritability, character association and genetic diversity were evaluated on randomized complete block design with three replications among seven-yard-long bean genotypes. The genotypes were significantly variable for the studied characters. High genotypic and phenotypic coefficient of variation was observed in number of pods per plant and pod yield per plant. Accordingly, high heritability together with high genetic advance in percent of mean was observed in number of pod per plant, pod diameter and hundred seed weight. The correlation studies revealed that pod yield per plant showed significant positive correlation with number of seed per pod, number of pods per plant while significantly negative correlation with days to marketable harvest at both genotypic and phenotypic level. Path analysis revealed days to first flowering, days to maturity, number of pods per plant, pod weight and number of seeds per pod had direct positive effect on pod yield per plant. The studied genotypes were clustered into 3 groups with highest of inter-cluster distance between cluster I and III while lowest between cluster II and III. The genotypes of cluster I exhibited higher mean performance while lower in cluster III for important traits including pod yield per plant.

 Two parents with contrasting characters were used, viz; Gd2002SPSN.29 and Ziraa-9 described as (P1) and (P2) respectively. They were selected from the sesame breeding program, Gedarif Research Station, ARC, Sudan. In season 2004 the two parents were crossed to produce F1 hybrid. In season 2005 parents and their F1 were grown. Part of the F1 was selfed to produce F2 and the other part was back crossed to both parents to produce Bc1 and Bc2 progenies. In season 2006 the parents (P1, P2), and their F1and F2 and back crosses (Bc1, Bc2) populations were evaluated in a randomized complete block design with three replicates. A wide range of variability was exhibited for most of the characters. The highest seed yield was obtained by the BC2 (714 Kg.ha-1), while the lowest was obtained by the BC1 (286 Kg.ha-1). Considering the nature and magnitude of gene action, improvement of days to 50% flowering, days to maturity, plant height, number of branches plant-1, height to first branch, height to first capsule, capsule length and 1000-seed weight could be achieved through simple pedigree method while hybrid breeding would be most effective for seed yield plant-1 and seed yield.ha-1International Journal of Environment Volume-4, Issue-3, June-August 2015Page: 111-120

The caper plant is widespread in Sicily (Italy) both wild in natural habitats and as specialized crops, showing considerable morphological variation. However, although contributing to a thriving market, innovation in caper cropping is low. The aim of the study was to evaluate agronomic and production behavior of some biotypes of Capparis spinosa L. subsp. rupestris, identified on the Island of Linosa (Italy) for growing purposes. Two years and seven biotypes of the species were tested in a randomized complete block design. The main morphological and production parameters were determined. Phenological stages were also observed. Analysis of variance showed high variability between the biotypes. Principal component analysis and cluster analysis highlighted a clear distinction between biotypes based on biometric and production characteristics. Production data collected in the two-year period 2007–2008 showed the greatest production levels in the third year following planting in 2005. In particular, biotype SCP1 had the highest average value (975.47 g) of flower bud consistency. Our results permitted the identification of biotypes of interest for the introduction into new caper fields. Further research is needed in order to characterize caper biotypes in terms of the chemical composition of the flower buds and fruits.

Yam (Dioscorea spp.) is a valuable food security crop in West Africa, where 92% of the world production occurs. The availability of quality seed tubers for increased productivity is a major challenge. In this study, minitubers weighing 1, 3, and 5 g produced from virus-free single-node vine cuttings of two improved yam varieties (Asiedu and Kpamyo) growing in an aeroponics system were assessed for suitability in seed production at a population of 100,000 plants ha−1. A 3 × 2 factorial experiment with randomized complete block design and three replications was set up during the cropping seasons of 2017 to 2019 at the International Institute of Tropical Agriculture Research Station in Kubwa, Abuja, Nigeria. Results showed field establishments of 87%–97.8%. Yields differed with minituber size, variety, and cropping season; the highest was 31.2 t ha−1 in 2019 and the lowest, 10 t ha−1 in 2018 from 5 and 1 g Kpamyo minitubers, respectively. The estimated number of tubers produced per hectare by 1, 3, and 5 g minitubers was 101,296, 112,592, and 130,555, with mean weights per stand of 159.2, 187.3, and 249.4 g, respectively. We recommend using less than 6 g minitubers for seed yam production due to their high multiplication rates.

We investigated the interaction between genotype by trait, and an experiment was conducted at the University of Debrecen. Two maize cultivars, FAO340 and FAO410, were studied in a randomized complete block design with four replications. This experiment was applied to the six fertilization treatments. Fertilizer levels were NPK0 (control) (N:0, P2O5:0, K2O:0), NPK1 (N:30, P2O5:23, K2O:27), NPK2 (N:60, P2O5:46, K2O:54), NPK3 (N:90, P2O5:69, K2O:81), NPK4 (N:120, P2O5:92, K2O:108), and NPK5 (N:150, P2O5:115, K2O:135). The first principal component showed 54.24%, and the second principal component showed 20.75%, which explained the total squares interaction using the AMMI model in the case of the FAO410 hybrid. As regards the FAO340 hybrid, the first principal component showed 58.18%, and the second principal component showed 18.04%, explaining the total squares interaction using the AMMI model in the FAO410 hybrid. In the GGE biplot on FAO410, the first and the second principal components covered 91.20% of the total data in this analysis. Accordingly, the desirable treatment was NPK5, followed by NPK4, NPK2, NPK3, NPK1, and NPK0. NPK4 and NPK5 had the most desirable treatments for the number of seeds per row, chlorophyll, weight of 1000 seeds, and stem diameter in the case of the FAO410 hybrid.

Abstract Development of maize hybrid for tidal swampland was initiated by selecting and combinate some superior line genotypes that tolerate to the restrictions in target environment. This study aimed was to evaluate the capability of ten maize lines result of selection on tidal swamp acid sulphate soils to obtain GCU, GCA, and heterosis values based on parental yield averages. The experiment has consisted of ten fine line genotypes which have selected in 2019 at the tidal swamp. Each parent was crossed in half-diallel combination, resulting in 46 entries, including the inbred parents. The entries were planted in a randomized complete block design with three replications. The research was conducted on Bajeng Research Station Experiment 5°18’S and 119°30’E from September 2020 to January 2021. The result shows that GCA ability and SCA ability was significant to yield in the form of grain (15% moisture content), the number of ear per plot, ten ear weight, ten corncob weight, ear harvested weight, 1000 seeds weight, plant height, ear length and the number of seed per ear. Grain yield of W6xW9 crosses obtains the highest value of 9.36 tha−1, non-significantly different to hybrid check P35 (9.35 tha-1). The highest GCA value in the grain yield character was obtained on W9 parental line (0.64**). The highest SCA was obtained on the crossing of W7 x W8 (2.61). The highest heterosis value was revealed in W5 x W10 hybrid (4.80). However, W7 x W8 crossing heterosis value was 2.34, indicate that a high SCA effect did not usually generate high heterosis. To perform high heterosis value, W10 was good as female parental.

A field study was conducted at Tennessee State University's research station to evaluate the effect of hardwood bark mulch on the winter survival of garden mums. A randomized complete block design was used. Cultivars used were adorn, encore, grandchild, jackpot, legend, minnautumn, minnwhite and triump. At the end of the flowering season the tops were removed leaving a four inch stubble in the mulch. The number of mum plants that resumed growth the following spring were counted for each cultivar. There was a difference in the winter survival of the different cultivars as well as a significant difference in the mulch treated and the control. Grandchild and jackpot were most cold hardy followed by encore, minnwhite, minnautumn, triump, legend, and adorn. Grandchild and jackpot with four inches of hardwood bark mulch had an 88 percent survival while the control had a 44 percent survival. Adorn. had a 51 percent survival with four inches of mulch and a 20 percent survival in the control. This data shows that hardwood bark mulch holds a great potential for providing excellent winter protection for garden mums.

The experiment on evaluation of open pollinated genotypes of Yard long bean (Vigna unguiculata ssp. sesquipedalis) was conducted during summer season of 2016 and 2017 at Horticulture Research Division, Khumaltar Lalitpur to assess the variability in the genotypes and yield potentiality for commercial production. The experiment was laid out in Randomized Complete Block Design with three replications. Six genotypes viz. Great Wall 01, Great Wall 02, Great Wall 03, Great Wall 04 and Great Wall 08 were compared with Khumal Tane. Observations were recorded on fresh pod yield and yield attributing parameters. The plant vigor and plant uniformity score (1-5 scale) was not found significantly different among the tested genotypes. The highest number of pods per plant (46) was observed on the variety Great Wall 03 and the lowest number of pods (33) on Great Wall 01 followed by Khumal Tane (39). The fresh pod yield was noted the highest with Great wall 03 (24 t/ha) followed by Great Wall 2 (19.4 t/ha). The lowest yield was observed with Khumal Tane (12.7 t/ha). Likewise, Great Wall 03 was found tender whitish with green color when it matures and spongy type of fruit with mid early maturity (85-95 days) along with long harvesting period of 30-35 days. Although Great Wall 02 scored 4.7 in plant uniformity (1-5 scale) and 4.4 in plant vigor (1-5 scale) it was characterized as thick fleshy and whitish green color at maturity with smooth straight type flesh having early maturity (70-80 days) which could gain the demand of the market early compared to most popular Khumal Tane. Thus, among all genotypes Great Wall 03 and Great Wall 02 were recorded best for further evaluation and recommendation.
