The study was conducted in Puri District of Odisha, India along with the introduction of a new technology Alternate Wetting and Drying (AWD) in Rabi 2015. AWD was a very low cost water saving technology and farmers were made aware about it in the selected study area in nine villages, three in each three blocks of Puri district. The selected 144 farmers, 16 from each village who had adopted AWD were interviewed through a pretested interview schedule. 15 variables were taken to assess the socioeconomic profile of the farmers. The variables were quantified in terms of frequency and percentage. Respondents were categorized with respect to variables like social participation, cosmopoliteness, mass media exposure, extension participation, extension contact, progressiveness and scientific orientation on the basis of mean score and Standard Deviation The study revealed that majority (57.63%) of respondents belonged to middle aged category, maximum of 44 respondents (30.5%) having primary level education, majority (68%) of the respondents were marginal farmers, majority (78%) of respondents had high level of social participation, there was homogeneity among extension participation, average annual income, extension contact, mass media exposure, social participation and heterogeneity among all other variables.

In Pakistan's arid agricultural landscape, this 4-year (2020–2023) study on silty loam soil examined the relationships between sowing methods, irrigation practices, rice yield and water productivity. Using a randomized split block design, no tillage (NT) with alternate wetting and drying (AWD) and a furrow-irrigated narrow bed (NB) emerged as being consistently competitive, showing potential for sustainable rice cultivation. Key findings indicate that AWD significantly enhances water productivity (11–35%) and increases yield (2–10%) compared to conventional practices. Drip-irrigated wide beds (WBs) conserve substantial amounts of water (73%) but may compromise rice yield (4–47%). This study provides valuable insights into the dynamic outcomes and distinct performance trends of different rice varieties. The results suggest a potential maximum yield increase of 2–22% through optimized practices, and replacing rice may increase yield by 25–231%. Conversely, the selection of improper irrigation schedules and sowing methods for the given soil and crop conditions may lead to a yield reduction of up to 47% in high-yielding rice varieties. These findings may help to establish a foundation for further research investigating informed decision making for sowing and irrigation methods. The potential scalability of the identified technologies and further in-depth simulation strategies across diverse agroecological zones in Pakistan holds promise for widespread adoption, enhancing the sustainability of rice farming in the region.
