Consumer preference is a consumer attitude towards a product choice. The needs and desires of consumers are very varied and can change because of the factors that influence consumers in choosing products. This study aims to analyze consumer preferences and what attributes are considered by consumers in making decisions to choose processed fish products. This research was conducted at Bandar Djakarta Restaurant, Summarecon, Bekasi City in February - March 2021. Primary data collection techniques used accidental sampling of 30 respondents, while secondary data was obtained from Bandar Djakarta Bekasi, FPIK Unpad Library and Unpad Public Library. The analytical tool used to determine consumer preferences is the measurement of attitudes using the Likert scale and the attribute analysis tool that is considered in product selection, namely the Chi Square analysis. Based on the results of the analysis of the level of consumer preference at the Bandar Djakarta Restaurant, it shows that the most preferred processed product is shrimp. The attributes that are considered in purchasing processed shrimp products are consecutively good taste, low price, and easy to find, high nutrition and family preference at the same level.

The study has analyzed effects of extreme flooding on output of selected root and tuber crops in Anambra State, Nigeria for the period of 1990-2019using secondary data collected on cassava, yam and sweet potato output from the agricultural production survey of Anambra State Agricultural Development Programme and annual averages of rainfall from the Nigeria Meteorological Agency inAwka station. Data collected were analysed by using multivariate simple linear regression and trend analysisin linear trend analysis and line graph. Results respectively showed an increasing trend in output of cassava, yam and sweet potato within the researched period with a depression in output of cassava and yam in 2014 and 2015. The regression results showed that coefficients of determination (R2) values of yam output were (0.620), cassava output (0.560) and sweet potato (0.580), which implied that 63%, 56% and 58% changed in output of roots and tuber crops accounted for rainfall within the research period. Specifically, rainfall (0.002) was positively related to yam output at (p<0.05). This implied excessive amount of rainfall resulting flooding, which influenced the output of production of yam. Rainfall (-0.015) and (-0.003) were negatively related to output of cassava and sweet potato at 5% probability level, which indicated extreme rainfall translating into flooding, which adversely affected the output of cassava and sweet potato in this area. The result of the tested hypothesis showed that extreme flooding had significant negative effects on output of roots and tuber crops in the researched area. Based on results, it was concluded that extreme flooding deleteriously affected output of root and tuber crops in Anambra state, Nigeria. Therefore, farmers were advised to change their crop production technologies including time of planting to suit changes in rainfall pattern in order to avert their adverse effects.

Most suitable sowing date and high yielding varieties are the primary agricultural practices to enhance production and productivity of chickpea. Hence, a field experiment was carried out to evaluate the effect of sowing dates on yield and yield components of chickpea varieties in the main cropping season of 2019 at Toke Kutaye, Ethiopia. Treatments consisted of four sowing dates (September 4th, September 14th, September 24th, and October 5th) and four kabuli varieties of chickpea; namely Dube (standard check), Dalota, Teji and Ejere. The experiment was laid out in split plot design using factorial arrangement with three replications where sowing date treatments were assigned to the main plots and varieties to sub plots. Dalota variety produced the highest number of pods (79.7) per plant. the main effects of sowing date and varieties were significantly different on biological yield. Highest biological yield (3776.9 kg ha-1 and 3761 kg ha-1) were recorded from September 24th and September 14th sown plots, respectively. Among varieties tested, the highest biological yield (3723.8 kg ha-1) was obtained from local variety. Highest grain yield (2415.4 kg ha-1) was recorded from plots sown on September 14th whereas Dalota variety produced highest grain yield (2051.25 kg ha-1). In case of harvest index, highest (67.9% and 59.6%) was recorded from September 14th sown plots and Dalota variety, respectively. Therefore, Dalota variety and September 14th sowing date emerged as best among all tested treatments and could be recommended for chickpea production in the study area.

An experiment was conducted at Entomology field laboratory, Bangladesh Agricultural University, Mymensingh during the rabi season of 2019-2020 to investigate the incidence of aphid and whitefly on chilli and effect of some biorational and new generation insecticides for controlling those insects. The presence of aphids was first identified on 2nd week of January at the vegetative stage of the chilli plant with the density of 2.34 per leaf. Then a gradual increase and a subsequent decrease were observed in the aphid population. The population density was reached to the peak level by first week of February with the mean number of 16.69/leaf. Thereafter, the population decreased in a gradual manner and reached to the minimum level by the end of 3rd week of March. In case of whitefly, similar trend of incidence but comparatively lower incidence was recorded from seedling to fruiting stage. On the other hand, five biorational and new generation insecticides were evaluated against these insects in field condition. All tested insecticides were found very effective except Shurter 505 EC (Cypermethrin + Chlorpyriphos) regarding reduction of aphids and whitefly populations, curled leaf development and increases of yield of green chillies. Among rest of the four insecticides, the Imixam 70WDG @ 0.30 g/L water (Imidacloprid + Thiamethoxam) was found most effective that was significantly followed by 0.20 g/L. This findings was closely followed by Gain 20 SL (Imidacloprid), Lumectin 10WDG (Lufenuron + Emamectin Benzoate) and Biotrin 0.5% (Matrine) respectively considering all the parameters studied.

Protected farming is one of the innovations used by farmers to control pests and climatic conditions and therefore improve yield of vegetables. However, these structures also provide an ideal environment for biotic factors such as insect pests and diseases. In this study, a survey of 60 farmers was conducted to determine the types of vegetables cultivated under protected structures, insect pests and management practices employed by farmers using structured questionnaires. Data was analysed through descriptive statistics using Statistical Package for Social Sciences (SPSS). The results showed that most farmers grew tomato, cabbage, swiss chard, rape and peppers. Farmers considered insect pests as the major constraint to vegetable production. The most important insect pests found infesting farmers’ vegetables were aphids (Aphis gossypii), tomato leafminer (Tuta absoluta), bagrada bug (Bagrada hilaris) and cutworm (Agrotis ipsilon). To manage these pests, farmers relied heavily on chemical pesticides which are dangerous to them and to the environment. It is therefore important to develop an integrated pest management plan that farmers can use to reduce use of pesticides.
