9pgs, This study was conducted to identify the agricultural extension needs of women farmers and to assess the impact of their participation in agricultural extension programs on vegetable production in the area. A sample of 145 women farmers from five Grama Niladhari (GN) divisions of the DS division was randomly selected for the study. Data were collected from a researcher administered survey and analyzed using descriptive statistics and a regression analysis. As per the results, a significant number of the women farmers have
participated in most of the extension and training programs. However, some of them haven’t registered in the farmer organization present in the area. Agricultural extension agents of the area have focused on dissemination of more information regarding modern farming technologies, organic farming, application of agrochemicals and fertilizers, and improving market systems. The majority of women farmers have
used the knowledge received from the extension programs in vegetable farming activities. Furthermore, there is a significant and positive relationship between participation in extension programs by women farmers and an increase in vegetable production. Therefore, encouragement of women farmers to register in the farmer organization, provision of timely important extension service to them, organizing training programs, and workshops to disseminate agricultural information are crucial to further enhancement of vegetable production in this area.
8 pages, via Online journal, The use of tomato (Solanum lycopersicum) grafting is gaining traction across the United States, but small-scale growers face the challenge of creating optimum postgrafting healing conditions. The practice of blocking light for a period of 2 to 4 days while maintaining high humidity is commonly recommended for healing grafted tomato transplants; however, research is exploring alternatives to this practice. The present study investigated a low-input healing method for grafted tomato transplants with a specific focus on light and the use of propagation heat mats to regulate substrate and healing chamber air temperatures during the 7-day healing process. We hypothesized that 4 days of light exclusion and the use of propagation heat mats would improve grafted tomato transplant survival and growth. ‘Cherokee Purple’ was used as the scion and ‘RST-04-106-T’ was used as the rootstock. The whole plot factor was heat [propagation mats set at 80 °F (heat) or no propagation mat (no heat)] and the subplot factor was light exclusion (0, 4, or 6 days of dark). The highest survival rate among treatments was 97% in 0 days of dark with no heat treatment; survival decreased to 84% in 4 and 6 days of dark with no heat treatments. The plant survival rate was 96% with 0 days of dark and heat treatment; however, the survival rates were 63% and 45% for the 4- and 6-day dark treatments, respectively. The scion stem diameter was largest for transplants grown in 0 days of dark, but there was no difference in stem diameter due to heat treatments. There were no differences among scion or rootstock biomasses due to heat or light treatments. These results demonstrate that propagation mats set at 80 °F to regulate the substrate temperature were detrimental to grafted transplant survival under extended periods of light exclusion. However, this finding creates the basis to explore lower levels of substrate temperature modification. Our work also indicates that light exclusion may not be necessary for healing grafted tomato plants regardless of root-zone temperature treatments. Future work should examine the interactions of various substrate and air temperatures under full light conditions and their effects on grafted tomato transplant survival and growth. This work contributes to the ongoing research of how to optimize low-input healing methods that may be readily adopted by small-scale tomato growers.
