Kireçli Toprakta Börülcenin Fide Gelişimi Üzerine Vermikompost ve Mikoriza Uygulamalarının Etkileri

Organic matter has a positive effect on the uptake of nutrients in the soil. The increase in mycorrhizal activities in the soil causes an increase in the activities in the rhizosphere region. Vermicompost is among the most useful organic fertilizers that can be added to the soil in recent years. Soil microflora is capable of realizing the return of mineral substances. Akkız cowpea variety was used in the study: The experiment was carried out as a viol study with 3 replications according to the randomized blocks trial design. In the study, seedling development was achieved by mixing vermicompost (0, 15, 30 and 45%) with and without mycorrhiza in a soil containing 16% lime into the viols in order to develop seedlings. Sufficient minerals have been applied to the plants for their growth. Seedlings were harvested when they were 40 days old, and seedling measurement parameters and macronutrients in plant leaves were checked. As the amount of vermicompost increased, it caused an increase in the above-ground fresh and dry weights, root fresh and root dry weights of the seedlings. As the organic fertilizer mixture increased, the nitrogen, phosphorus, potassium and magnesium concentrations of the plant leaves increased. The addition of mycorrhiza to the rearing medium has led to different results in the investigated characteristics. Addition of increasing organic fertilizer ratios in the study, Organic fertilizer and bacteria application of cowpea cultivars were effective in increasing the development of plants in calcareous soils.

Agromorphological Evaluation of 44 lines of Mung Bean (Vigna radiata (L.) Wilczek) Introduced in Burkina Faso

Mung bean (Vigna radiata L. Wilczek) is an important annual legume which is well suited to dry areas, like Burkina Faso where it is still an orphan legume. The present study was conducted to evaluate 44 mung bean genotypes introduced in Burkina Faso and to determine genetic diversity in this collection using both quantitative and qualitative traits. A field experiment was conducted in an augmented bloc design with three blocks and an extraearly maturing cowpea variety as check. Data were recorded on six (06) quantitative traits and seven (07) qualitative traits. For qualitative traits, diversity was revealed in four parameters including hypocotyl’s color, seed coat color, pods and stem pubescence. Significant genetic variability was revealed among genotypes for all the quantitative characters. Phenotypic coefficient of variation (PCV) was higher than Genotypic coefficient of variation (GCV) for all characters studied indicating the influence of environmental effect on the characters. The GCV and PCV estimates were high for number of pods per plant followed by plant height and hundred seeds weigh. The high heritability coupled with high genetic advanced as percent of mean observed for these traits suggest an important genetic gain in genetic improvement for these characters. The genetic diversity observed was grouped into five clusters. Mungbean lines were grouped into four clusters and the cowpea variety used as check crop in this trial was clustered apart. This genetic diversity, both qualitatively and quantitatively, will help enrich local biodiversity in terms of legumes in general and mung bean in particular and constitutes an important basis for a future mungbean breeding program.

A Comparative Study between Cowpea Variety C-152 and Local Variety in Tumakuru District (Karnataka), India

Pulses are the second important group of crops after cereals, providing high dietary protein (20 to 25%), along with rich supplement of calcium and iron. They play an important role to enhance soil fertility through biological nitrogen fixation and also pass on the benefits to associated non legume and subsequent crops. In Handanakere area farmers cultivate local varieties which are low yielding. A field experiment was conducted in the farmers’ fields to know the performance of C-152 cowpea variety with local cowpea variety. The results indicated that C-152 has performed better compared to local varieties in growth and yield parameters. Higher income is generated by the cultivation of C-152 cowpea variety.

Protein quality of autoclaved cowpea varieties as influenced by anti-nutritional factors

One hundred and ten (110) weanling male winstar strain rats were used to determine the protein efficiency ration (PER) and net protein ration (NPR) of five cowpea samples. PER ranged from 1.06 in IT 81D-1137 to 1.91 in 1784E-1-108 while values in autoclaved samples ranged from 1.55 in IT81D-1137 to 2.78 in 1784E-1-108. for NPR, raw samples gave values that ranged between 2.44 and 3.57 in 1781D-1137 and 1784E-1-108 respectively. Autoclaved samples gave NPR values that ranged from 2.72 to 4.47 in IT 8ID-1137 and IT84E-1-108 respectively. In the raw and autoclaved cowpea diets, trypsin inhibitor, lectin and tannic acid were negatively correlated with PER and NPR while HCN and phytic acid had positive relationship with these indicators of protein quality. In autoclaved samples cowpea variety IT84E-1-108 had the highest PER and NPR values showing that it would support growth to a reasonable extent.

In this study, the effects of on 20 April, 5 May, 20 May, 5 June, 20 June, 5 July and 20 July sowing times application in Kahramanmaras and Sanlıurfa conditions on the quality criteria of Simal cowpea variety were researched. The experiment was established in 2015 as a randomized trial design with four replications. The pod length, number of grain of each pod, dry hay weight, moisture ratio, oil ratio, protein ratio and starch ratio characteristics of Simal variety (Vigna sinensis L.) were investigated. At the end of the research, it was noted that the number of grain of each pod, dry hay weight, the moisture ratio, the oil ratio, the protein ratio of cowpea, in terms of the locations, sowing times and locationxsowing time interactions were significantly different. It was determined that the length of pod is insignificant in terms of sowing time, and starch ratio was significantly showed differs in terms of location and location x sowing time interactions. The grain number of each pod, the weight of dry hay, the moisture ratio, the fat ratio, the protein ratio, starch ratio of cowpea were reported varieties from 7 to11.37 unit, from 361 to 1631 kg da, from 10.87 to 13.44%, from 1.28 to 2.11%, from 22.81 to 25.45%, from 42.11 to 49.77% respectively. As a result, it was observed that the characteristics of the cowpea investigated were affected by the environmental conditions.

Pests and Diseases Associated with Yam Bean (Pachyrhizus erosus) Cultivation at Farmers’ Levels in the Central Region of Benin

Roots and tubers are one of the most important crops that provide food security in West Africa. Thus, Pachyrhisus erosus with its various potentials, is planned to be introduced in Benin to improve the nutritional quality of the population. Prior to that, this study aimed at assessing pests and disease of P. erosus in the agroecological conditions in the central parts of Benin. Conducted at experimental field in Savè during two consecutive years, experiments were laid in a completely randomized block design with 4 replications and three treatments including EC 533 and EC Kew cultivars of P. erosus and cowpea variety named Kpodji-Guèguè. Results showed that the major pests collected from P. erosus namely Ootheca mutabilis, Medythia quaterna, Piezotrachelus varium, Megalurothrips sjostedti and Brevipalpus phoenis were not so far reported in it. Compared to cowpea, pest’s infestation and their damages were lower on P. erosus. Infestation severity on leaves and the percentage of perforated green pods ranged from 0.7% to 3% against 0.8% to 88.9% and from 12.5% to 16% against 57.2% to 64% respectively on P. erosus and cowpea. Cercospora disease caused by Cercospora canescens and yam bean leaf blight caused by an unknown fungus were observed. Cercospora disease affected cowpea and P. erosus while yam bean leaf blight affected only P. erosus. This study provides additional data on pests and diseases associated with P. erosus worldwide and alerts farmers regarding their management.

Effects of interaction between cowpea variety and the application of plant powders on Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae) infestation of stored cowpea seeds

An integrated pest management scheme involving seed resistance and the application of powder of Cymbopogon citratus, Alstonia boonei, Hyptis suaveolens, Azadirachta indica, Loranthus braunii and Lycopersicum esculentum as protectant against the seed bettle, Callosobruchus maculatus (Fabricius), was evaluated in the laboratory at ambient temperature (29±3°C) and relative humidity (65±5%). Six resistant cowpea accessions selected from previous studies were treated with the six plant powders at 1.25% w/w in a 6×7 factorial arrangement fitted into a completely randomized design with five replicates. Seed treatment with any of the six plant powders on six accessions resulted in significantly higher adult mortality, lower oviposition rate, adult emergence inhibition, lower seed damage and higher seed germination over the control, Protection ability of the plant powders was influenced by the cowpea accessions used.
