Problem: Workforce shortages in the diagnostic fields of health care prompted conducting a study about possible barriers or influences about using distance education for didactic delivery.

Methods: A cross-sectional study design was used. 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.

Results: 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.

Conclusion:  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.

The present study was conducted at Research Farm of ICAR- Research Complex for Eastern Region, Patna, Bihar during rabi 2020-21. Eight insecticides were evaluated against aphid, Brevicoryne brassicae 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 B. brassicae.

DOI: 10.9734/cjast/2021/v40i2431500

Background: Climate change inflicts negative consequences on food production especially on smallholder farms needed to achieve food security. Sustainable farming techniques seem to be the bridge between climate change and food security.

Aims: 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.

Study Design: Using a questionnaire survey.

Place of Study: Bamenda Highlands, Cameroon.

Methodology: 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).

Results: 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, P=0.000), age (r=0.450, P=0.000), level of education (r=0.430, P=0.000), no till (r=0.19, P=0.016), crop rotation (r=0.158, P=0.040), and intercropping (r=0.227, P=0.045) all showed significant positive relationships with knowledge of sustainable farming at α=0.05.

Conclusions: Sufficient knowledge and capacity development on sustainable farming may decrease usage of unsustainable farming practices, hence improving the adoption of sustainable farming practices.

The study was conducted to analyze the influence of yield and economic viability of tomato (Solanum lycopersicum Mill) under varietal replacement demonstration in Bhagalpur District, Bihar, India during Rabi 2018-2019. Varietal adoption demonstrations were conducted on tomato by the active participation of the farmers. The improved technologies consist disease resistant variety (Kashi Vishesh), balanced fertilizers (Soil test based) application and integrated pest and disease management, etc. (All the recommended practices were provided to the selected farmers. The data related to the cost of cultivation, production, productivity, gross return and net return were collected as per scheduled and analysed. Results of the study revealed the higher yield in the demonstrations was recorded (498 q/ha) as compared to farmers practice traditional adopted by the farmers (396 q/ha). The percentage increase in the yield over farmer’s practice 25.75 was recorded. The technology gap, extension gap and technology index were computed 132 q/ha, 102 q/ha and 20.95% respectively. The demonstrated field gave higher net return Rs. 4, 02,000/- and B: C ratio and incremental demonstrated B: C ratio is 1: 4.12 and 1: 5.18 respectively. The result of the study indicated the gap existed in the potential yield and demonstration yield is due to soil fertility and weather conditions. Present results clearly show that the yield and economics of tomato can be boost up by adopting recommended technologies.

Maize (Zea mays L.) is the third most important cereal crop after wheat and rice. Improving maize production is considered to be one of the most important strategies for food security in the developing countries. The farmers in Kandi areas usually grow their own saved seed which comprises of composites and landraces due to which maize production in the area suffers due to low productivity. Considering this scenario, a number of hybrids were developed in order to improve yield and productivity in order to enhance their income. Hence evaluating the performance of hybrid maize genotypes in terms of yield in specific agro ecology is very crucial for horizontal expansion. The study was aimed to conduct the preliminary evaluation of 12 maize hybrids to determine their grain yields. The hybrids were ranked according to their superiority in yield over check.

An experiment using twenty genotypes of chickpea (Cicer arietinum L.) was conducted during Rabi season of 2019-2020, to find the genetic diversity using D2 statistics. The experiment was laid out in randomized block design with three replications at the experimental field of Himgiri Zee University, Dehradun. The observations was recorded on  nine quantitative characters where five randomly selected plants were taken the average was computed while the traits days to 50 % flowering and days to 100 % maturity was taken from plot basis. Results revealed that the genotypes were grouped into 4 clusters where Cluster-I had fifteen genotypes and cluster II had three genotypes while one genotype each was present in cluster III and IV. The seed yield per plant contributed maximum towards genetic diversity (32.00 %) followed by plant height at maturity (14.00 %) and number of secondary branches (9.00 %). The maximum intra cluster distance was found in cluster II (164.691) indicating that the 15 genotypes including in the cluster II were most divergent. However, maximum inter cluster distance was noticed between cluster I and cluster II (313.247) which could be used in hybridizing program.

The Red Mud has focused through major industrial and scientific research in industrial waste valorization. Red mud is the discarded produce of alumina extraction processes from its parent the bauxite ore. Its high alkalinity causes it to be kept in large quantities, resulting in increased deforestation. Annually, it is estimated that 64.2 MMT of red mud wastes are formed around the world, and India produces about 9MMT with less hope of being reused, posing a serious threat of pollution and contamination of both soil, ground water and the environment. Large numbers of research have shown that this bauxite solid waste can be refurbished to make construction bricks, pavement tiles, ceramic materials, but no full large-scale benign re-utilization have been made. The intent of the research is to probe in to the applications of red mud in the construction and various sectors, giving emphasis on Indian context. Other researchers' observations were considered and analyzed in terms of environmental, economic, and technical feasibility to fulfill zero waste demand due to red mud.
