The experimental design was a randomized complete block with three replicates. The treatments included; Poultry manure (PM), Moringa leaf (ML), NPK fertilizer (NPKF), NPK fertilizer + Moringa leaf (ML+ NPKF), poultry manure and Moringa leaf (ML+PM), and control (C). At 2 weeks after planting (WAP), PM, NPKF, and ML+PM gave okra plant height of 3.74 cm, 3.98 cmand 3.82 cm, respectively, which were higher than 2.7 cm for C. While ML gave the highest plant height of 4.05 cm, which was higher than other treatments. Of all the treatments, ML+PM gave the highest fruit weight of 1.343 t/ha and differed (P &lt; 0.05) from the rest of other treatments; while C had the least fruit weight of0.199 t/ha. ML+PM, NPKF, and ML+ NPKF gave total fruit number per plant of 47, 44 and 36 respectively, which differed (P &lt; 0.05) to other treatment and the C gave the least fruit number of 15.67 per plant. The results showed that the application of PM+ML improved the growth and yield of okra, hence poultry manure and moringa leaf should be used instead of NPK fertilizer, which can also lower the cost of production.</p> 2020-01-13T00:00:00+00:00 ##submission.copyrightStatement## http://journalajrcs.com/index.php/AJRCS/article/view/30085 Identification and Abundance of Fruit Fly Species Responsible for Fruit Drop of Sweet Orange (Citrus sinensis L. Osbeck) in Benue State, Nigeria 2020-04-05T21:26:53+00:00 S. O. Atanu samonaanu@gmail.com B. C. Echezona K. I. Ugwuoke <p><strong>Background and Objective: </strong>Citrus is one of the most important and among the top ten widely cultivated fruits in Nigeria. It is produced more in the Guinea and Sudan Savanna zones of the country with Benue State having the highest annual production. In the South of Savanna region of Africa, particularly in Nigeria; despite the economic, nutritional and health benefits of citrus, limited research work has been carried out on the identification and control of fruit flies of economic importance to the crop. The objectives of this study are to identify and determine the abundance of the fruit fly species responsible for fruit drop of citrus in Benue State, Nigeria.</p> <p><strong>Materials and Methods: </strong>Fruit fly identification was done through fruit culture experiment carried out in the College of Agronomy Teaching and Research Farm, Federal University of Agriculture, Makurdi in October 2014 and October 2015.The experiment was a 2 x 3 factorial in a completely randomized design with four replications. The two factors were Zones (Zone A and B) and Varieties (Ibadan Sweet, Valencia and Washington Navel). Ten naturally infested orange fruits from four randomly selected citrus trees of each variety in each zone were weighed and placed in each plastic rearing box with dimension 39 x 27 x 26 cm containing sterilized moist soil securely covered with 1 mm mesh net for pupation and adult insect emergence. Emerged adults were killed using Mobil insecticide (Cyphenothrin), counted, sexed and stored in specimen bottles with 70% alcohol for preservation and later identification.</p> <p><strong>Results: </strong>Fruit fly species identified from citrus fruit culture were:<em> Bactrocera invadens</em> (Drew), <em>Ceratitis capitata</em> (Weid) and <em>Dacus bivittata</em> (Biggot).&nbsp; <em>Bactrocera invadens</em> were the most abundant species and accounted for 63.70% in Washington navel and 63.10% in Valencia in 2014 and 2015 respectively. The varieties showed no significant differences (p&gt;0.05) on the abundance of <em>Ceratitis capitata</em> and<em> Dacus bivittata</em> in 2014. In 2015 however, Ibadan Sweet variety showed significant difference (p &lt; 0.05) on the abundance of<em> Ceratitis capitata</em> (28.30%) when compared with other varieties (15.8%) each.</p> <p><strong>Conclusion:</strong> Fruit fly species responsible for citrus fruit drop in Benue State were <em>Bactrocera invadens</em> (Drew), <em>Ceratitis capitata</em> (Weid) and <em>Dacus bivittata</em> (Biggot) with<em> Bactrocera invadens</em> (Drew) recorded as the most abundant species.</p> 2020-03-27T00:00:00+00:00 ##submission.copyrightStatement## http://journalajrcs.com/index.php/AJRCS/article/view/30086 Farmers' Indigenous Knowledge Practice for Crop Protection: A Case Study of Ant Protection on Teff (Eragrostis teff) Crop in North Wollo, Ethiopia 2020-04-06T02:52:52+00:00 Chanie Derso diribkassaw@gmail.com <p>The study was conducted under selective Kebeles in Kobo district of North Wollo Zone in the North eastern part of Amhara Regional State, Ethiopia. Although farmers have imperative experience with indigenous knowledge to reduce and eliminate the effect of ant over teff crop, there is no any research document reported with this regard. Thus, the aim of this research is to explore farmers' indigenous knowledge on ant protection on teff crop. To do so, descriptive research design was adopted. From 400 farmers in selected kebeles, a total of 200 household farmers in five kebeles, 40 in each, were selected using purposive sampling techniques. In-depth interview with their culture, custom and in comfort and survey were used to collect both quantitative and qualitative data. Then, the quantitative data were analyzed using IBM SPSS and the qualitative information was also summarized properly. Based on the analyzed data, the highest percentage of respondents (44.5%) were between the ages of 30-50 years while the lowest percentage (24%) of respondents found below the age of 30 years and the remaining percentage were above the age of 50. According to the interviewed data and survey results, farmers have used DDT (98%), ash (82%), herbal mulching (100%), burning on nest (38%), damping nest (64%). In general, this research tried to reveal the non chemical methods of indigenous knowledge used in the protection of teff crop. So that, it is better to investigate the chemical nature and the adverse effect of the above mentioned plant species on ant and need to scale up into industrial production.</p> 2020-04-01T00:00:00+00:00 ##submission.copyrightStatement##
