A population of 467 program directors was identified. Four hundred-sixty email addresses were functional. A convenience sample of 167 responded to an online survey about perceived barriers to using distance education for program delivery.</p> <p><strong>Results:</strong> Program directors responded about perceived barriers to using online, distance education as part of educational delivery for academic programming. Concerns included lack of quality of coursework, and students; along with lack of adequate equipment for offering distance education teaching, faculty workloads and lack of release time.</p> <p><strong>Conclusion:&nbsp; </strong>While distance education is a viable solution for offering diagnostic, didactic program content, perceived and real barriers to its use are impacting workforce development, especially in rural, health care and educational deserts.</p> Reed Brooks, Jodi Olmsted ##submission.copyrightStatement## Thu, 16 Sep 2021 00:00:00 +0000 Field Evaluation of some Molecules for Management of Brevicoryne brassicae Linnaeus in Cauliflower, Brassica oleracea L var botrytis <p>The present study was conducted at Research Farm of ICAR- Research Complex for Eastern Region, Patna, Bihar during <em>rabi</em> 2020-21. Eight insecticides were evaluated against aphid<em>, Brevicoryne brassicae </em>in cauliflower and found that all insecticidal treatments were significantly superior over untreated control, in reducing the population of aphid however; significant differences existed among the various treatments. Flubendiamide20% WG @ 0.4gm/l was found most effective followed by lufenuron 5.4% EC @ 1ml/l and others showed intermediated effects in reduction of aphid population. The least effective treatments were neem oil and diafenthiuron in reducing the population of <em>B. brassicae</em>.</p> Ritesh Kumar, Md.

Fruits <p>Some physical properties of palmyrah fruit were investigated in this study. The average values of major, medium, minor and geometric mean diameters of fresh whole palmyrah fruit were 11.54,10.45, 9.85 and 10.64 cm respectively at 47.34 % (w.b) moisture content whereas that of palmyrah nut were 8.59, 7.35, 4.99 and 6.79 cm respectively at 8% (w.b) moisture content. Sphericity, surface area and aspect ratio were found to be 91.94%, 359.17 cm2 and 0.90 for fruit and whereas that of nut were 79.19%, 145.16 cm<sup>2</sup> and 0.86 respectively. The average mass of the individual palmyrah fruit and nut was 927.78 and 248.10 g whereas bulk density was 525.92 and 693.0 kg/m<sup>3</sup> respectively. The coefficient of static friction on mild steel, glass and plywood surfaces were 0.27, 0.21 and 0.25 for palmyrah fruit and 0.36, 0.28 and 0.27 for nut respectively. The angle of repose of palmyrah fruit and nut were 30.77 and 44.03 respectively.</p> P. C. Vengaiah, S. Kaleemullah, M. Madhava, A. Mani, B.

Sustainable farming techniques seem to be the bridge between climate change and food security.</p> <p><strong>Aims:</strong> To evaluate knowledge and practices of sustainable agriculture within smallholder farmers in the Bamenda Highlands, by identifying methods of pest and disease control, soil preservation options, and their different tillage practices, i.e., conventional versus sustainable practices.</p> <p><strong>Study Design:</strong> Using a questionnaire survey.</p> <p><strong>Place of Study:</strong> Bamenda Highlands, Cameroon.</p> <p><strong>Methodology:</strong> A sample of 175 smallholder farmers (25 from each of the seven administrative divisions) were questioned about their tillage, soil preservation, crop protection, and knowledge of sustainable farming practices. Data collected were analysed and summarised to obtain frequencies and percentages. Pearson Product Moment Correlation (PPMC) was used to test for significant relationships between the pairs of variables (age, level of formal education, sex, some tillage and soil preservation practices).</p> <p><strong>Results:</strong> Out of the 161 farmers who returned the answered questionnaire, 111(68.9%) agreed to have knowledge of sustainable farming but yet 158(98.1%) were still involved with conventional unsustainable practices such as tillage with the formation ridges, and 150(93.2%) used mineral fertilizers and pesticides. Crop rotation 102(64.2%), intercropping 110(68.3%), and legume integration 124(78.0%) were the most used sustainable farming practices. Sex (r=0.419, <em>P</em>=0.000), age (r=0.450, <em>P</em>=0.000), level of education (r=0.430, <em>P</em>=0.000), no till (r=0.19, <em>P</em>=0.016), crop rotation (r=0.158, <em>P</em>=0.040), and intercropping (r=0.227, <em>P</em>=0.045) all showed significant positive relationships with knowledge of sustainable farming at α=0.05.</p> <p><strong>Conclusions:</strong> Sufficient knowledge and capacity development on sustainable farming may decrease usage of unsustainable farming practices, hence improving the adoption of sustainable farming practices.</p> Christian Tegha Kum, Aaron Suh Tening, Martin Ngwabie, Cornelius Tsamo ##submission.copyrightStatement## Mon, 20 Sep 2021 00:00:00 +0000
