Field experiment conducted from November 2021 to April 2022 on farmers' fields in Sukamulia, East Lombok, Indonesia, aimed to determine the growth and yield response of chili (Capsicum frutescens L.) to treatment with Paclobutrazol concentrations and phosphorus fertilizer doses during the rainy season. The factorial experiment was arranged in a randomized block design with three blocks and two treatment factors, namely Paclobutrazol concentrations (0, 50, 100 and 150 ppm) and phosphorus fertilizer doses (0, 30, 60 and 90 kg/ha P2O5). Data were analyzed using ANOVA and Tukey's HSD at 5% significance level. The results showed that Paclobutrazol concentration significantly decreased growth rates of plant height and the doses of P fertilizer increased the number of productive branches per plant. However, the interaction between the treatment factors had a significant effect on flower initiation and fruit weight per plant, with the highest chili fruit yield, i.e. 549.5 g/plant, was obtained on chili plants receiving treatment combination of 150 ppm Paclobutrazol concentration and P-fertilizer dose of 90 kg/ha P2O5. This treatment combination also resulted in the earliest flower initiation (at 42.2 days after planting).

In the face of climate change, the optimization of crop diversification policy in Côte d'Ivoire must go through research and promotion of crops of interest that require little water, including Aloe vera. However, in view of its slow growth in nursery, the improvement of growth substrate fertility by the supply of nutrients is necessary. Thus, this study aims at assessing the effects of six organic matter formulations on Aloe vera growth in nursery. To this end, a completely randomized block experimental design comprising six treatments and three replications was carried out. The amendments tested were cow dung, chicken droppings, charcoal, banana tree stems and ripe plantain and dessert bananas. The results showed substrate pH variability (6.67 to 7.87) depending on the amendments. Leaf emergence speed increased with cow dung from the 80th day after planting. Similarly, the highest number of leaves was obtained with cow dung (9.33 leaves). With 22.89 cm in average length and 1.65 cm in average width, the leaves generated with cow dung were also the longest and widest. This study showed that cow dung promotes rapid Aloe vera growth in nursery.

Rice production in East Java has decreased, which is related to climate change. Uncertain climate results in a shift in planting time. Climate projection scenarios are a solution to see future climatic conditions. One of the analyses used is the water balance. This study aims to study the water balance to determine the rice (Oryza sativa L.) planting time shift based on climate projection scenarios. The research was conducted from March to July 2022 in four districts of East Java. The materials used are average rainfall data and average temperature data for 2000-2020, climate projection data from the CNRM-CM5 and HadGEM2-ES models for 2025-2050, field capacity data, and permanent wilting point data. This study uses a selected sampling technique and the location is chosen as one of the rice production centers in East Java. This research uses exploratory descriptive analysis, statistical descriptive analysis, and the Thornthwaite and Mather method of water balance analysis. The research results show a shift in the planting time of rice plants in four districts in East Java for the years 2025-2050. Malang District experienced a change in the planting time of rice plants of 2 basics, Gresik District experienced a shift in the planting time of rice plants of 2-6 basics, Banyuwangi District experienced a change in planting time of 3-5 basics of rice and Pasuruan District experienced a shift in planting time of rice plants of 1-4 basics.

This work was aim to evaluate the pathogenicity and the level of aggressiveness of ten strains of Fusarium oxysporum f. sp. elaeidis (Foe) on palm oil seedlings susceptible to vascular wilt. For this purpose, the radial growth, sporulation and the morphological characteristics of ten strains of Foe from the farm palm of the Cameroon Development Corporation (South-west) were studied in vitro. In addition, 500 oil palm seedlings susceptible to vascular wilt and aged 5 months were distributed in a randomized complete block device, and inoculated with said strains. External symptoms of Fusarium wilt were observed on those seedlings and the correlation between these parameters was also investigated. The data collected in prenursery did not establish a significant difference in the aggressiveness of the isolates. However, regarding the pathogenicity, 7 strains have shown a high pathogenicity. As for the radial growth, strain F presented fastest growth was 8.12 cm in diameter, unlike the strainI whose growth was the lowest is 3.98 cm in diameter. The C strain is one that is abundantly sporulated126,5x105spores/ml; however, isolates B and J do not sporulate. No correlation was detected between the different parameters. But, considering the results obtained, the F and I strains could be the most aggressive and can potentially be used to test the timber yard of the specialized Centre for oil palm research of La DIBAMBA to select the most resistant to vascular wilt.

Microgreens are a new class of vegetables that are harvested within 7-21 days after sowing, have a lot of nutritional potential and are a new trend in the food industry. One type of microgreens that is grown commercially is broccoli. The nutrients in broccoli microgreens are 4-6 times more than mature plants, contain good vitamin C, and contain antioxidants that can help protect the body from the harmful effects of free radicals. Cultivating microgreens requires the right planting medium and nutrients to support plant growth. The research objective was to obtain the interaction between the types of growing media and the nutrients used to increase the growth and yield of broccoli microgreens. This research was carried out from October to November 2022 at the Greenhouse of the Faculty of Agriculture, Andalas University. The study was a two-factorial experiment in a completely randomized design (CRD) with 3 replications. The first factor is several types of planting media, namely soil, cocopeat, and rock wool. The second factor consisted of several types of nutrition, namely AB mix and young coconut water. Observational data were analyzed using statistical analysis of variance test F. If F Count treatment is greater than F Table 5% then it will be continued with the DNMRT test at 5% level. The results showed that there was an interaction between the type of growing media and the nutrition given to the growth of broccoli microgreens. The use of rock wool growing media and AB mix nutrition gave the best response for the observed parameters of seedling height, number of leaves, fresh weight, and chlorophyll content. The results of the antioxidant analysis carried out when harvesting broccoli microgreens gave a red color change when given HCl, whereas if NaOH was added drop by drop there was no blue color change. So it can be concluded that broccoli microgreens contain betacyanin.

Climate change is currently posing a challenge to social cohesion in rural communities in Côte d'Ivoire, given the social upheavals it has caused. In Ouangolo, for example, the perfect cohabitation between Fulani herders and indigenous farmers is gradually being called into question by the adverse effects of climate change. The small hydraulic dams are drying up, creating social divisions as a result of conflicts of interest over their control. It is this issue that this study addresses. It is based on a qualitative approach and requires the use of Alain Touraine's sociological action theory. In the end, it emerged that climate change has led to a reduction in Ouangolo's water resources, to the point where the last water points are now the subject of covetousness between the local farmers and Fulani herders. Each party wants to preserve its access to water resources. The Peulhs, observing the partial or total occupation of the grazing and ox-grazing areas around the dams that they own, make the animals cross into the cultivated areas, destroying everything in their path. This does not leave the locals indifferent. They express their indignation. So, in a context where these watering holes have become an existential issue for these populations, there is a risk of major confrontation over control of the water. In Ouangolo, conflict is a recurring phenomenon between these two players.

The purpose of this study is to use the Landsat satellite image of Dongguan from 2005 to 2021, combining the dimidiate pixel model and stochastic matrix method, to calculate the vegetation coverage grade and land use type area, express the urbanization process with construction land, and analyze the relationship between the temporal and spatial evolution characteristics of vegetation coverage and urbanization expansion. The results indicate that: (1) The overall distribution of vegetation coverage is consistent, showing a spatial distribution characteristic of "high in the east, low in the west, and lowest in the north". (2) During this period, the overall coverage area of medium low, medium, and medium high vegetation decreased, while both low and high vegetation coverage areas increased. (3) The area of construction land has increased significantly, with the increased built-up area coming from bare land, followed by vegetation and water bodies. (4) The spatio-temporal evolution characteristics of vegetation coverage are closely related to urbanization expansion. This study can provide reasonable scientific data support and an effective decision-making basis for evaluating the regional ecological environment, construction, and urban development of Dongguan City.

Tractor fuel consumption is a vital parameter in management of farm machinery. Parameters affecting tractor fuel consumption in litres per hectare(L/ha) during ploughing operation in Uyo was investigated. The study was conducted at the University of Uyo teaching and research farm, Uyo in Akwa Ibom State, Nigeria. The soil in the study location was characterized as clay loam. Effects of operation parameters on fuel consumption for ploughing operation were investigated using One-Way Repeated Measures Analysis of Variance. The findings of the study indicate that at ˂0.05 significance level, operation parameters had significant effect on tractor fuel consumption during ploughing operation. The study had identified factors affecting tractor fuel operation during ploughing operation in the study location.

The objective of the current study was to evaluate the effect of adding different levels of ginger extract in the formulation of camel sausage. Four treatments were investigated: T1 control and the other treatments (T2, T3 and T4) were treated with 5, 10, and 15 % ginger extract (v/w). Chemical, physical, sensory properties and histological examination were evaluated. Sausages treated with ginger extract had higher moisture, lower fat content and no significant differences in protein content. Collagen content was significantly increased in treated cooked sausages. Fat and moisture retention significantly increased in camel sausage treated with ginger extract. The addition of ginger extract significantly improved the color and shrinkage measurements. A Light micrograph of camel sausage treated with 10% ginger extract exhibited severely broken muscle fibers and severely destructed connective tissue. Sausage treated with 10% ginger extract recorded the highest score for texture, tenderness and overall acceptability.
