This study was borne out of the fact that rice farming and cattle rearing are predominant in the northern parts of Nigeria. But there have been increasing conflicts between farmers and herdsmen particularly in north-central. To address this problem, this study empirically looked at the nexus between sensitization on gains from paddy grazing and farming practices in rice production. Data were collected from three hundred and twenty respondents with the aid of a structured interview guide and field survey. It was found that instead of using organic manure, Urea (55%) and NPK (36.9%) fertilizers were applied on the rice farms. Most (89.4%) of the respondents were not sensitized on the benefits of paddy grazing to the dairy cattle, environment, and soil. Results of the t-test indicated that no significant difference existed in the farming practices for rice production in Niger and Benue States (t = 8.9). The level of sensitization on paddy grazing correlates with the farm practices of the respondents (r = 0.69). This study concluded that respondents did not aware that paddy grazing could lead to increased rice and milk production.

Technological development and climate change dictate farming practices, which can directly affect irrigation water requirement and supply. In this article, the water supply reliability (WSR) of 62 major Korean agricultural reservoirs was comprehensively evaluated for varying climate and farming practices. Field surveys identified the recent divergence from standard rice farming practices and a 45-year daily weather data set (1973–2017) was examined to understand the phenomenon of climate change. Effective rainfall increments mitigated the imminent surges in rice irrigation water requirements driven by warming-led accelerated crop evapotranspiration rates; therefore, climate change marginally influenced the WSR of selected reservoirs. The transplanting period and associated water consumption were the primary deviations from standard rice farming practices. A significantly prolonged transplanting period seriously compromised the WSR of agricultural reservoirs and the maximum number of unsafe reservoirs was detected for a 24-day increase in the transplanting period. A watershed/irrigated area ratio of less than 2.5 was the lower threshold below which all the reservoirs had unsafe WSR regardless of the climate change and/or farming practices. Recent variations in farming practices were the primary cause of reservoir failure in maintaining the WSR.

Tidal swamplands are considered the national food security platform in Indonesia. Residues from the excessive chemical input used in the rice production affecting the environment, farmers’ health, and the safety of the product. Similarly, one can expect that excessive chemical use in tidal swamplands can also threaten rice production system sustainability. This study aimed to assess and identify factors influencing the sustainability of rice farming practices in tidal swamplands of South Sumatra, Indonesia. A survey was carried out to obtain information through direct interviews with 150 farmers in Muara Telang, South Sumatra, Indonesia. The Indonesia rice check was employed as indicators to assess the sustainability of rice farming practices in tidal swamplands. A percentage index was to categorize the sustainability status. A regression analysis with the Tobit model was applied to identify factors influencing the sustainability of rice farming practices. The result showed that the average sustainability index was 25.53%. It indicated rice farming practices in tidal swamplands tend to be unsustainable. The significant factors influencing the sustainability of rice farming practices were farmer’s education and household size. A policy recommendation is proposed to enhance the implementation of sustainable agriculture practices by the rice farmers in tidal swamplands.

The study examined factors affecting rice farming practices of rural farmers in Ogun and Niger States, Nigeria. Three hundred and twenty  respondents were selected through multistage sampling procedure. Frequency distribution, percentages and mean, student’s t-test and regression analysis were used for data. All analysis was done at 5% level of significance. There was a significant difference in the farm practices of the rice farmers in Niger and Ogun States (t = 8.39, p ≤0.05). Factor affecting rice farming practices was determinants of rice production output (β = -0.13, p ≤0.05). There was difference in the farming practices of rice farmers in Ogun and Niger States. Agricultural extension services, particularly, in Ogun State should expedite action in organizing training that can facilitate adoption of better farming practices in order to increase rice production and income generation for the rice farmers, while government and input suppliers should make fertilizers available and affordable. Keywords: factors affecting farming practices; rice production; rural rice farmers;

The research aimed to account for the rice technologies practiced by farmers of Canavid and Dolores, Eastern Samar. These two municipalities are considered as the rice major product owns of Eastern Samar. It sought to determine the degree of adoption of modern and indigenous rice technologies and to identify the problems met by the farmers in using said technologies. A total of 57 farmers served as respondents. Percentage, means, ranks and ranges were used to analyse the data. The mean age of the respondents was 54.94 years old with intermediate as the highest educational attainment with 5.43 years of formal schooling. Majority were married with 17.68averageyearsof farming. The average farm size was 1.26 has. The respondents prepared their rice field by trampling, use of native seeds and by winnowing basket in cleaning the palay with a weighted mean score of 2.04, 2.5, and 2.23 respectively. Results also revealed that 71.05 percent were unsuccessful and 28.93 percent were successful or highly motivated while majority of the modern rice farmers were considered successful or highly motivated (67%). Lack of knowledge and skills about rice farming, farm implements, and limited capital were the problems met by farmers.
