Methods: Researcher managed and farmer implemented trails (RMFITs) constituted under randomized block design having five treatments with four replications were conducted at two farmers’ fields under Jaipur conditions. During 2016-2019, Farmer-Managed and Farmer Implemented Trials (FMFITs) in Gujarat and Rajasthan with Farmer-Managed Trials (FMTs) in Haryana, Tamil Nadu, Telangana, and Maharashtra were also conducted. Result: Sulkhania Bajra was superior in both grain (30.6 q/ha) and fodder (63.q/ha) yield as compared to the checks and was characterized by distinct long earheads (64.95 cm), higher plant height (193.13 cm) wit...

Benefit cost ratio is an important factor influencing the decision for adoption of a new variety ... more Benefit cost ratio is an important factor influencing the decision for adoption of a new variety in any new location. Farmers have been playing an instrumental role in ensuring food security by developing highly productive varieties which are also adapted to various (a)biotic stresses. Promotion and adoption of such varieties in new locations is required to provide profitable livelihood and to meet the growing demand of food crops. In order to determine the adoption of two such farmers’ developed varieties- DRK and Indrasan, a study was conducted in nine districts of Odisha and Chhattisgarh states during 2016, using the benefit - cost ratio (BCR) as the key parameter for decision making. Structured questionnaire and cost-benefit analysis approach were used for collecting the data and analysis. The highest benefit-cost ratio (BCR) of 2.26 was recorded in case of farmer’s variety DRK followed by Mahamaya (1.30), Swarna (1.12) and Indrasan (0.81). The variety DRK fetched 41.2 percent h...

Indigenous veterinary medications had provided necessary relief to farmers in regions where accessing quality services from conventional veterinary institutions were limited. This dynamic knowledge system needs to be strengthened, shared to younger generations for sustenance and adoption. A research study was initiated to involve farming communities in experimentation towards control of worm infestation, a framework to recognize custodians of knowledge and to share ways to scale up validated grassroots technologies. Most programs visualize generation of technology at research stations and envisage models to share to farmers. However evidence of originating technologies from farmer’s field based on creative knowledge of society and involving experimentation spirit of community has been limited. During the study efficacy of two indigen...

The aqueous and oil-based crude formulations were tested at two different concentrations each, in comparison with chemical, botanical and untreated control. Both the crude formulations were effective in the management of green leafhopper and white backed plant hopper in a dose-dependent manner, however, the aqueous formulation was more efficacious as compared to the oil-based formulation. These herbal formulations are an eco-friendly, cost-effective and safe alternative to chemical control measures for the management of paddy pests and can easily be incorporated in the integrated pest management (IPM) programs for the control of sucking pests in Paddy.

M astitis is a disease of economic importance causing havoc in dairy sector throughout the world.... more M astitis is a disease of economic importance causing havoc in dairy sector throughout the world. National mastitis control program envisages minimizing spread of infection, protecting mammary gland tissue and curtailing entry of pathogens through teat orifice. Farm productivity has been limited with lack of appropriate technologies to meet location specific requirements (Kadivendi et al., 2015). Periodic assessment of milk is important to know the health status of udder (Syed et al., 2009). Dairy farmers differ in undertaking risk, seeking alternative source of employment and level of motivation in any region. The enhanced occurrence of coagulase negative staphylococci (CNS) is cause of concern (Reyher and Dohoo, 2011; El-Jakee et al., 2013). Incidence of subclinical mastitis (SCM) upto 50% in cows was reported in different regions (Gianneechini et al., 2002; Alhussien et al., 2015). In India, SCM occurs forty times more than clinical form with annual economic loss of Rs. 4365.32 crore (NAAS, 2013; Bhanderi et al., 2014). These findings reflect that SCM needs to be given adequate attention (Abrahmsen et al., Short Communication Abstract | Mastitis is an ailment of economic importance affecting livestock worldwide. Several initiatives have been initiated globally through investment of highly skilled human resource along with unconstrained financial support. The nature of disease, cost of medication, difficulties in reaching out to needy livestock population and accessibility to diagnostic facilities are main impediments. Innovations from creative individuals in similar setting can address such difficulties better. Hence, listening to farming communities will enhance the scope of intervention and leverage experimental learning in society. Indigenous livestock system sustained by outstanding traditional livestock holders can complement efforts of scientific community. Appreciating the role, mainstreaming of indigenous veterinary medications has been revitalized. However, successful evidence of communities' role in bringing out suitable researchable issues, and response to meet, share and discuss with them were limited. The study illustrates successful outcome to bring desired attention in this area. During this engagement with civil society a novel innovative medicine coded AHP/BSD/SCM in treatment of sub-clinical mastitis was evaluated and was found effective. A specific research question posed by indigenous healer provided different perspective to control mastitis. This research study offers art of engaging different stakeholders to construct a meaningful situation for expressing and implementing creative, affordable technologies. It highlights the role of society in sharing a solution that has been collectively preserved by them and essential direction to formal system.

There were six treatments viz., control, FYM @ 25 t ha -1 , 1⁄2 NP, 1⁄2 NP + K, NP and NP + K and from each treatment soil samples were collected in the years 1980, 1990 and 2000 analysed for active, passive and slow pools. The data were analysed for correlation, regression and path co-efficient statistical tools. The pools of soil organic matter concentrate as soil organic carbon under the treatments application of FYM @ 25 t ha -1 followed by NP + K treatment in the year 1990. In the context of active pools of SOM, maximum of water soluble carbon and water soluble carbohydrates were recorded under FYM application @ 25 t ha -1 in the years 1990 and 2000, respectively. Vigorous flush o...
