Abstract

Climate changes, rising warmth, drought, and CO2, are now seriously influencing agriculture. In this study, four separate greenhouses (labeled GH1, GH2, GH3, and GH4) were built with plastic roofs and walls, except GH1, which had three walls with mesh to evaluate the impact of temperature stress on growth, biomass, and yield of rice variety IR50404 under different temperature regimes. The control treatment group was grown ambient, next to these greenhouses. GH1, GH2, GH3, and GH4’s temperatures were from 0.9 oC to 3.1 oC higher than the ambient (as control). Carbon dioxide concentrations in GH2, GH3, and GH4 were recorded higher than the ambient, from 34.1 ppm to 48.2 ppm. Total vegetative dry matter was reduced from 15.9% to 20.5%, while grain yield declined from 20.8% to 24.6% when the mean temperature increased from 2.9 oC to 3.1 oC. High temperature or a combination of high-temperature stress with elevated CO2 concentration reduced the grain yield and total vegetative dry matter.

Abstract

The study was carried out to assess the yield performance of groundnuts grown on ridges and non-ridges by communal farmers of ward 8 in the Guruve district of Mashonaland Central province, Zimbabwe. Interviews, surveys, questionnaires, and observation methods were used for data collection. A sample of 60 respondents was selected from a list of groundnut farmers in the ward. The results showed that 43% of the respondents were growing groundnuts on ridges, while 57% of the respondents were growing groundnuts on non-ridges. No farmers used both farming practices. The results showed that more yield per hectare was obtained by farmers who used ridged farming practices than nonridging techniques. The area planted with groundnuts varied significantly (P<0.001) with the farming practice (ridging and nonridging) and the farming seasons. The rate of adoption of the ridging farming technology was affected by the age of the household head, level of education of the household head, sex, and age of the household head. More females participated in the growing of groundnuts than their male counterparts. In conclusion, groundnut yield was comparatively higher on ridged farming technology than on non-ridging technology; farmers are encouraged to plant groundnuts on ridges to cherish the highest production benefits. However, more training is needed for farmers to take upon new farming technology and regard groundnuts as a cash crop rather than a women's crop as well as to improve the household income.

Abstract

The botanical insecticide nanoemulsion is a pesticide having an oil phase and aqueous phase that spontaneously emulsify and range in size from 20 to 200 nm. Bio-combi extracts frequently contain intricate combinations of active ingredients that may work in concert to increase bioactivity. The goal of the study was to develop the optimal nanoformulation and investigate the physiological effects of a synergistic nanoemulsion made from Tephrosia vogelii leaves and Piper aduncum fruit extracts as a substitute pesticide for Spodoptera frugiperda larvae. Low-energy spontaneous emulsification with a magnetic stirrer was used to create nanoemulsions, which were then subjected to a toxicity and food absorption test. Malvern's Zetasizer Nano (ZN), which was used to analyze the insecticidal nano formulae for PSA, revealed that the particle sizes for the 1:1, 3:1, and 1:5 ratios were 204 nm, 4724 nm, and 97 nm, respectively. Only the 1:5 formula, which is classified as a nanoparticle, met the standards for a nanoemulsion and produced S. frugiperda mortality of 82.34% at a concentration of 0.56%, and the LC25, LC50, and LC95 values were 0.1, 0.22, and 1.59%, respectively. The analyzable results demonstrated that the mixed nanoemulsion was additive at the LC50 value was 0.95 while the LC95 value was 0.70%, meaning only marginally synergistic

Abstract

The bacterial species Xanthomonas axonopodis pv allii (Xaa) is an important pathogen causing leaf blight in shallots. The use of botanical pesticides with nanoemulsion formulations has become a common alternative. This study aims to determine the characteristics and optimum concentration of the mixture of essential oil of Piper aduncum and fragrant Cymbopogon nardus waste. Nanoemulsion formulations are made using spontaneous emulsification methods. Besides, testing Bacillus thuringiensis strain MRSNR3.1 and its secondary metabolites toxicity against Xaa was carried out by the diffusion method using paper discs to determine the diameter of the inhibition zone. The results demonstrate that all four concentrations, 1%, 2.5%, 5%, and 7.5%, could control Xaa bacteria. A concentration of 1% is considered more optimal than the other three   concentrations in bactericidal effects against Xaa, as manifested in the formed clear zone (diameter of 3.17 cm). Besides, Bacillus thuringiensis strain MRSNR3.1 and its secondary metabolites were also effective againstXaa after four days of incubation with inhibition zones of 3.04 ± 0.44and 2.21 ± 0.28, respectively. Hence, it is concluded that nanoemulsion at 1% concentration and Bacillus thuringiensis strain MRSNR3.1 have  bactericidal properties that can be used to control Xaa

Abstract

The rice harvesting process has progressed a lot. Farmers used to harvest simply using a sickle and a simple thresher machine, while nowadays, they are using the latest harvest machine, called Combine Harvester. Technological developments should enable farmers to gain more significant benefits, such as higher production, a shorter processing time for harvesting, and lower costs incurred during harvesting. This study aims to describe the characteristics of farmers who use Combine Harvester technology and farmers who use Thresher harvesting technology. This study also compares the costs of rice harvesting and production of both farmers in lowland rice farming in Kenagarian Kambang Barat, Lengayang Sub-District, Pesisir Selatan District. The farmers sampling chose as many as 30 farmers purposively for each of those using a Combine Harvester and Thresher, so the total number of farmers to be interviewed was 60. The data analysis method used in this study is the analysis of the average difference test of the independent sample Z-test model. The research finds that farmers' main reasons for using the Combine Harvester were faster harvesting times and less labor. While the main reason for farmers using the Thresher was that its cost is considered the same if using a Combine Harvester machine. Moreover, the research indicates a significant difference in the cost of harvesting and producing rice using both harvesting machines. The harvesting cost of the Combine Harvester was lower than Thresher, which was Rp. 3,543,149 and Rp. 4,385,543 respectively. The difference in harvesting cost of these two harvesting machines was Rp. 842,394. Furthermore, the rice production using the Combine Harvester is higher than the thresher harvesting machine, which was 5,312 Kg/Ha/MT and 5,089 Kg/Ha/MT, respectively, with a difference of223 kg

Abstract

Food loss is a worldwide concern, especially the losses from the fresh tubers because of their quick rottenness during post-harvest without proper preservation. Meanwhile, the tuber is an excellent source of carbohydrates that can be used in a broad range of food and other industries. Therefore, creating added-value products from crops has been considered an intriguing idea for decades in order to reduce this matter and also can utilize raw materials from agriculture. This research aimed to determine and evaluate the effects of starch addition from Jicama on the characteristic of peel-off gel masks. Five different formulations were made with increased starch concentration at 1%, 2%, 3%, and 4%, and a control sample was formulated without adding starch. Organoleptic, spreadability, homogeneity, irritation, viscosity, pH, peeling time, and antibacterial and antioxidant activity were parameters in evaluating gel formulations. The best formula showed a homogenous consistency, there was no irritating reaction, and it had the highest sensory point from the panellist. The acidic degree and viscosity were 5.53 and 32867 cPs, respectively, which adhered to the Indonesian National Standard (SNI 2007) for facial skin products; the gel had good spreadability, and the peeling time was less than 30 minutes. Moreover, the gel presented an active antibacterial activity against Staphylococcus aureus; and antioxidant activity. According to the results, Jicama is recommended for application in making good quality peel-off gel mask products at 4% concentration.

Abstract

It is very important to use adaptation technologies in crop fields to mitigate the adverse effect of increasing temperature and limited amount of water on crop growth and yield. Application of Super Absorbent Polymers is one of the technologies which can be used to overcome the impacts. This study was conducted at the Open University of Sri Lanka, during the period of 2019 to 2021. Experimental design consisted with three factors, i.e. temperature conditions (32-33 0C and 35-360C), irrigation intervals (3days, 5days and 8days) and application of Zeba (Super Absorbent Polymers) (2g of Zeba and with not Zeba). Treatments were arranged in Complete Randomized Design with three replicates. Growth and yield parameters of chilli were collected and statistical analysis of the data (ANOVA) was performed using Three-Factor Factorial Design and compared for the significance by using a Revised Least Significant Difference  test at p=0.05. According to the results, Zeba positively influences to mitigate the adverse effect of increased temperature and water stress condition imposed by longer irrigation interval. Under ambient temperature condition, treatment with Zeba, three day irrigation interval showed the highest yield of chilli. However, the yield of that crop was not significantly different from the treatments with five day irrigation interval and eight day irrigation interval under ambient temperature condition with Zeba. Therefore, due to the no significant difference, treatment with Zeba and eight day irrigation interval can be named as the best cost-effective treatment which can be used to cultivate with limited amount of water under ambient temperature condition. Under increased temperature condition, treatment with Zeba, three day irrigation interval showed the highest yield. However, it is not significantly different from the treatment of five day irrigation interval, with Zeba under increased temperature condition. Therefore, under increased temperature condition, irrigation interval can be extended up to five day when plants were treated with Zeba.
