Abstract:
Agricultural researchers in developing countries were not able to give much attention on the adoption studies of agricultural technologies until the period of Green Revolution. These technologies are disseminated in rural farming community by agricultural extension professionals to boost farm efficiencies and productivity. This paper presents the systematic review of methods employed by previous researchers in studying agricultural technology adoption with special reference to rice. The review focuses on the study of rice technologies adoption in the Philippines and other related studies conducted by a Filipino author in other countries in the Asian Region. From 391 adoption studies identified, 22 papers were selected and included in the review. These papers were retrieved from Scopus database. This review revealed that papers focused on studying the adoption of rice cultivation practices employed quantitative techniques. Institutional factors were found to critically influence the decision-making of the farmers to adopt production technologies.

Abstract:
Ethiopia is one of the most populated countries in Africa. Agriculture employs over 70% of the population. It is dominated by small-scale farmers who practice rain-fed mixed farming by using traditional technology, adopting a low input and low output production system. As a result, it is vulnerable to adverse weather conditions. Cereal crops provide food for majority Ethiopians, so most agricultural transformation plans prioritize increasing cereal crop productivity. However, about five million people experience food insecurity each year and require support. Population growth, environmental degradation, conflict, and climate change are the most serious threats to nation’s food security. In a time when the food supply cannot keep up with population expansion, there is a need for holistic solutions to development-related issues such as food insecurity, malnutrition, and poverty. Despite Ethiopia being a center of origin and diversity for several food crops, the potential benefits of underutilized indigenous crops are yet not exploited. However, they can play a significant part in human nutrition, income, and medicinal value. As a result, crop diversification may be the best choice for achieving household food security. One way to help nation’s food systems diversify is to include more orphan crops. Even though a small portion of the country’s land is dedicated to underused crops, more than 20% of the population relies on them for food. Orphan crops, such as enset, which can feed 100 million people, can help to attain food security in Ethiopia. As a result, promoting and researching these crops is the most sustainable strategy for lowering and managing poverty and food insecurity in Ethiopia.

Abstract:
Plantain marketing offers great profit-making, yet it is unclear if these have translated to more profits, making it imperative to examine the drivers of plantain marketing. Primary data collected with structured questionnaire in purposive 2-staged random sampling were analyzed using net marketing income, marketing margin, marketing efficiency and multiple linear regression models. Plantain marketing was mainly done by married educated women, averaged 40 years of age, belonging to households averaging 6 persons. Net monthly profit of $63.51 (₦26,050.38), average marketing margin of 30.84% and marketing efficiency of 35.06% were returned. Suggesting plantain marketing is profitable and viable but largely inefficient. Cost of plantain and marketing experience were positively significant (p≤0.05). Plantain marketing faced constraints like seasonality of plantain, inadequate finance, price fluctuations, high transportation costs, bulkiness, spoilage/breakage and high plantain costs. Plantain marketers should form/join cooperatives to obtain low-interest loans, mitigate marketing costs and enjoy economies of scale.

Abstract:
Though Bench Sheko and Sheka zones have great potential for dairy production in Ethiopia, the majority of dairy producers’ could not get benefit from the sector in a sustainable way due to the low market participation problem. Hence, this study was designed to analyze determinants of market participation by dairy producers’ in Southwestern Ethiopia. Data from 160 sampled dairy producers were employed and analyzed by using the probit model. The model result shows the ownership of crossbreeds, utilization of improved livestock feeds and size of dairy cows’ ownership affect market participation decisions significantly and positively. While the number of children below six years and distance from the market is the significant factors determining the likelihood of dairy market participation negatively in southwestern Ethiopia. Therefore, demonstrations of improved livestock breed through supplying improved bulls and artificial insemination technologies, demonstration of improved livestock forages and concentrates through training, and organizing dairy marketing cooperative and dairy products collection centers are suggested to improve the market participation in the study area.

Abstract:
This study examined the farmer’s perception on climate change and adaptation strategies to mitigate the adverse effect of climate change in the agricultural sector of Gujarat. It used farm level information of 400 farmers who were purposely selected from 8 districts. Thereupon, linear, non-linear and log-linear production function models were used to examine the impact of climate change, farmer’s adaptation strategies and technological change on agricultural production in Gujarat. The descriptive and empirical results specify that adaptation strategies (i.e., change in showing time of crops, mixed cropping pattern, irrigation facilities, application of green and organic fertilizer, hybrid varieties of seeds, dampening of seed before planting, climate tolerate crops, organic farming and technology) have a positive impact on agricultural production. Thus, farmer’s adaptation strategies are useful to mitigate the negative impact of climate change in the agricultural sector. Maximum temperature and minimum temperature, precipitation and rainfall have a negative impact on agricultural production. However, the impact of these factors seemed positive in the agricultural sector when farmers apply aforementioned adaptation strategies in cultivation. Family size, education level of farmers, annual income of farmers, arable land, irrigated area, cost of technology, appropriate technology and financial support from government have a positive contribution to increase agricultural production in Gujarat.

Abstract:
Border-rows effect is an important research content of intercropping system. Milk vetch-rape intercropping is one of the typical intercropping patterns in southern China. However, research on the border-rows effect is very little, which has affected the application and popularization of the milk vetch-rape intercropping system. In this study, two field experiments were conducted from 2018 to 2020. The effects of monoculture, intercropping and different border-rows on agronomic traits and yield of rape were studied. The results showed that milk vetch had a significant effect on the first border-row of rape. The first border-row of rape diameter of root and secondary effective branch number is significantly higher than second and third border-row, and the rape yield per plant in the first border-row of intercropping milk vetch was 135%, 328%, 257% and 147% higher than that in the second, third, fourth and fifth border-rows respectively. The intercropping with milk vetch enhanced the number of pods per plant in first border-row by increasing the agronomic traits of rape, such as plant height, stem diameter, primary effective branch number and secondary effective branch number. In conclusion, intercropping milk vetch significantly improved the agronomic traits of the first and second border-rows rape, increased the yield of rape. So it is recommended that milk vetch intercropping with two rows rape, which has important guiding significance for the application and promotion of milk vetch-rape intercropping in the future.

Abstract:
In order to develop the suitable planting mode of maize in red soil dryland, improve the related plant and ear characters of maize, promote high quality and high yield, and improve economic benefits. The experiment was conducted in the Science and Technology Park of Jiangxi Agricultural University from May 13, 2020 to October 18, 2020 and from May 5, 2021 to October 7, 2021. Taking maize as the control, three intercropping treatments of maize intercropping soybean, maize intercropping peanut and maize intercropping sweet potato were set up to compare their effects on agronomic characters such as plant height, stem diameter and ear width of maize and yield. The results showed that the plant height and ear height of maize intercropping soybean reached the maximum in two years, with plant height of 208.9 cm and 191.9 cm, ear height of 80.2 cm and 58.4 cm, respectively. The ear length and grain number per row of intercropping treatment were better than that of monoculture treatment. The ear length of maize intercropping and soybean reached the maximum, which were 16.5 cm and 19.0 cm respectively, and the grain number per row was also higher than that of other treatments. The yield of maize intercropping soybean was the highest, 42.1 kg and 43.5 kg respectively in two years. Compared with monoculture, intercropping can improve stem diameter, ear height, ear length, grain number per row and other ear traits, so as to improve corn yield, among which maize intercropping soybean is the best. The results of grey correlation showed that ear length and plant height had a great influence on maize yield. The comprehensive analysis shows that the use of maize intercropping soybean model is conducive to achieve high quality and high yield.

Abstract:
In order to explore the effects of Chinese milk vetch and rape mixed sowing on rice yield and soil fertility, and select the best planting mode, five different ratios of Chinese milk vetch and rape mixed sowing were designed to study the effects of different ratios on rice yield, soil physicochemical properties and soil fertility in 0-10 cm, 10- 20 cm and 20-30 cm layers. Grey correlation analysis of soil nutrient and yield was carried out by using grey system theory. The influence of different soil layers on soil chemical properties was greater than physical properties. The effect on shallow soil is greater than that on deep soil. Mixed sowing of Chinese milk vetch and rape improved soil comprehensive fertility in all soil layers, and rice yield was the highest in 2M2R treatment. pH value had the greatest effect on actual rice yield, followed by available potassium. Therefore, mixed sowing of Chinese milk vetch and rape could significantly increase the yield of early rice and soil nutrient content, and the pattern of “1/2 Chinese milk vetch +1/2 rape-early rice-late rice” had the best effect.
