Abstract

A study on the control of watermelon pests was conducted in the Western region of Cameroon. The trial was laided on a randomized complete block design with three replications at the University of Dschang farm from December 27, 2019 to April 10, 2020 (dry season). The treatments were T1 (control plot), T2 Biotrin (Abamectin 5% at 375ml/ha), T3 Antario (Bacillus thuringiensis  1.4%+ abamectin 0.1% at 375g/ha), T4 Neem oil (0.3 to 1% Azadirachtin) at 7l/ha, 400 H2O/ha) and T5 (Emamectin benzoate 50g/kg, 250g/ha). Pest abundance, leaf infestation rate, plant growth parameters, and yields were assessed weekly from 26 days after sowing to three weeks before harvest. The results showed that Aphis gossypii (Hemiptera: Aphididae) the major pest (39.54±7.15) and Bemisia tabaci (Hemiptera: Aleyrodidae) (1.64±0.16) the second host infested watermelon. The peak of the leaf infestation rate is 20.97% at 40 DAS. The number of aphids was higher at 54 DAS (71.34±26.30) and for whiteflies at 68 DAS (2.83±0.54). The effect of the treatments was significant (P>0.05) for all parameters. The control plot was more infested with the highest mean leaf infestation rate, number of Aphids and whiteflies respectively 29.6± 2.30%; 158.03±29.59; 1.04±0.20 than Biotrin less attacked (4.11 0.89%; 2.21±0.4; 0.89±0.2). Biotrin, neem oil, Antario, and Emacot are comparable for all parameters. In summary, the lowest yield was obtained in the control plot (35.71±2.66t/ha) but was not significantly different (P˃0.05) from those of the other plots. Biotrin, neem oil, and Antario are bioinsecticide alternatives for Emacot and they should be applied before the 40DAS.

Research Paper | Extreme weather events and their impact on urban crop production By INNSPUB Journals

Mr. Asnath Alberto Malekela and Mrf. Pius Yanda from the institute of the Faculty of Arts and Social Sciences. The Mwalimu Nyerere Memorial Academy, Dar es Salaam, Tanzania. and Centre for Climate Change Studies, University of Dar es Salaam, Dar es Salaam, Tanzania wrote a research paper entitled “Extreme weather events and their impact on urban crop production: A case of Kinondoni District, Tanzania”. This article was published by the International Journal of Agronomy and Agricultural Research | IJAAR, under the publication of the International Network For Natural Sciences | INNSPUB.

Abstract

Extreme weather events are anticipated to increase the existing challenges and generate new combination of vulnerabilities, especially in developing countries. The agricultural sector is the most vulnerable due to overreliance on unpredictable rainfall. This study examined the impact of extreme weather events on urban crop production and its adaptation strategies applied by the farmers. Secondary data were collected through literature survey and primary data were collected using structured interviews, observations and focus group discussions. A total of 108 crop farmers were interviewed in two wards of Kinondoni District. The Statistical Package for Social Sciences (SPSS) version 20 was used to analyze the data and Pearson Chi-square was used to test the statistical significance between variables. The study observed that, farmers perceived extreme weather events including floods (39%), extreme temperatures (36%), and drought (25%). These extreme weather events affected negatively crop production leading damaging of crops and low yields (38%), outbreak of crop pests and disease (38%), drying of water sources (20%), and loss of soil fertility (4%). Crop farmers used various adaptation strategies such as crop diversification (28%), the use of pesticides (23%), changing of cropping patterns and planting calendar (16%), irrigation practices (18%) and replanting (10%). The study recommends for adoption of new farming systems such as vertical farming systems for better output with the use of limited water and land resources.

Seedlings characters of wheat as affected by soaking | Research Paper by IJAAR

Mr. AA Kandil, AEM Sharief, and Mr. WAHE Abido from the Agronomy Department, Faculty of Agriculture, Mansoura University, Egypt, and Mr. SRHA El-Bardisy from the Ministry of Agriculture and Land Reclamation, Egypt wrote a research paper entitled Seedlings characters of wheat as affected by soaking with chitosan and proline under salinity stress. This research was published by the International Journal of Agronomy and Agricultural Research | IJAAR, under the publication of International Network For Natural Sciences | INNSPUB. At the end of the research, they concluded that “From obtained results in this study it could be concluded that for maximizing seedlings characters of bread wheat Shandaweel 1 cultivar under salinity stress, it could be recommended to soaking with the mixture of chitosan at the rate of 0.75 or 0.50% and proline at the rates of 13 or 9mM for 6 h.” Let’s get some knowledge about it.
