“…Finally, the socio-economic constraints were poor infrastructures, cost of inputs being high, inadequate inputs, credit problems, lack of trainings, and lack of information. According to Ndiiri et al (2013), weed menace, high labour requirement for weeding, non-availability of weeders, and poor land drainage were the major constraints that rice farmers faced in their production. Haldar et al (2012) estimate that the most pressing constraint facing rice farmers is difficulty in undertaking management practices.…”

The study assessed rice farmers' access to credit and constraints in rice production in the Tolon District of Ghana. A total of 140 rice farmers were sampled for the study using multi-stage sampling technique. The probit model was used to estimate the factors that affected rice farmers' access to credit. The Kendall's coefficient of concordance was used to assess the constraints in rice production. The results of the study revealed that majority of the rice farmers accessed credit from family and friends and invested the credit into non-agricultural activities. The probit result revealed that age, marital status, member of farmer based organization, extension visit, record keeping and farm income were the significant variables that influenced rice farmers' access to credit. The results also revealed that high cost of inputs and pest were the most pressing institutional and technical constraints in rice production, respectively. The study recommends that credit should be converted to physical inputs and other services and delivered to farmers to help minimize credit diversion from the farm sector. Rice farmers should be encouraged to form farmer groups and keep records of farming activities considering the fact that it positively influenced farmers' access to credit. Subsidies should be provided on farm inputs. Effective ways of eliminating pest on rice fields should be developed since it was a major challenge facing the rice farmers in their production.

“…To use succinct, somewhat technical language, SRI practices enable farmers to produce more productive phenotypes from given genotypes, from both improved or unimproved varieties, as has been documented in numerous studies (e.g. [25][26][27][28][29][30][31][32][33]). …”

“…An increase in rice production worldwide by 60% or more is also urgently required to be able to meet the world's food demand from approximately 10 billion people by 2025 (Fageria, ). And because paddy agriculture is the largest water consumer of the agricultural sectors, reduced water use in paddy fields is essential to cope with imminent water shortage due to both inefficient water use and the lack of available water resources (Barah, ; Ndiiri et al ., ; Jung et al. , ).…”

Paddy fields comprise the single largest land use in Korea, occupying nearly 60% of arable land, consuming about 56% of the nation's water supply, and discharging a significant amount of agricultural non‐point source (NPS) pollution to public waters. Rural water resources conservation, the improvement of irrigation water productivity (IWP) and the reduction of NPS pollution from paddy fields are important issues in Korea. To quantify the issue, a field‐size rice‐plot study was conducted for 3 years comparing the treatment of a system of rice intensification (SRI) irrigation management and a conventional practice (CT). The SRI reduced the irrigation requirement at field level by 50% compared to the CT. The IWP of the SRI improved by an average of 94% over that of the CT. The average reductions of the NPS pollutants by SRI was 44.4% (BOD), 38.6% (SS), 35.3% (CODMn), 28.3% (CODCr), 23.8% (TN) and 36.3% (TN). The SRI treatment was concluded to have contributed to healthy rice plant growth, improvement of IWP and reduction of agricultural NPS pollution from paddy fields, which could significantly conserve rural water resources and improve water quality in Korea.
