    Comparative Economic and Gender, Labor Analysis of Conservation Agriculture Practices in Tribal Villages in India
    Lai, Cynthia; Chan, C.; Halbrendt, Jacqueline; Shariq, L.; Roul, P.; Idol, Travis; Ray, Chittaranjan; Evensen, Carl (International Food and Agribusiness Management Association (IFAMA), 2012)
    Marginal land use and subsequent natural resource degradation is a common issue among tribal villages in the Kendujhar district of India. In this study, Conservation Agriculture (CA) technologies at an experimental site, specifically the practices of intercropping and minimum tillage, were compared to conventional tillage practices of three tribal villages (145 households total) in this district. The impacts of CA implementation on gender, labor, and economic (yield and profitability) factors compared to conventional tillage practices were evaluated and used to make recommendations for future policy initiatives.
  • A comparative study of conservation agriculture production systems (CAPS) for tribal people of Odisha, India

    Tribal farming in Kendujhar district of Odisha, India is primarily based on traditional shifting cultivation which is becoming unsustainable - resulting in natural resources degradation, reduced production efficiency, and threatened food security. As maize (Zea mays L.) was the primary field crop grown by the tribal farmers, maize-based Conservation Agriculture Production Systems (CAPS) were taken as an innovative approach for conserving resources, enhancing productivity and sustaining livelihood through minimum soil disturbance, permanent organic soil cover, and adoption of diversified crop rotation. An on-station experiment was conducted in Kendujhar during June 2011 to March 2012 to estimate the effect of CAPS on yield and soil properties. The experiment was laid in a split plot design with four treatments and three replications. The treatment combinations comprised of two factors each at two levels: tillage (minimum and conventional), and cropping system (maize and maize+cowpea (Vigna unguiculata)). The maize seed yield both in conventional and minimum tillage were comparable, though it was highest in maize+cowpea under minimum tillage (5610 kg/ha). Maize+cowpea intercropping produced comparable seed yield (4955 kg/ha) to that of sole maize cropping (4825 kg/ha). As cowpea was an additional output without any reduction in maize seed yield and had high market value, maize+cowpea intercropping under minimum tillage recorded a highest net profit of $655/ha. Though there was no significant effect of CAPS on soil properties in the experimental year, it can be assessed over multiple years.
  • Effect of maize based Conservation Agriculture Production Systems (CAPS) under tribal farming situations of Odisha in India
    Idol, Travis; Pradhan, Aliza; Roul, Pravat K.; Mishra, K. N.; Halbrendt, Jacqueline; Evensen, Carl; Ray, Chittaranjan; Chan-Halbrendt, Catherine (Madison, WI: American Society of Agronomy, Crop Science Society of America, Soil Science Society of America, 2012)
    A summary of 2011-2012 trial plot results in terms of yield and profitability. Tillage and intercropping had no significant effect on maize yield (4890 kg ha 1) in the first year. The highest maize yield was recorded in maize+cowpea under minimum tillage (5610 kg ha 1). Economic return in case of intercropping was 38% higher than that of sole cropping, across both the tillage types. Though there was no significant effect of CAPS on soil properties in the first experimental year, trends were positive for soil pH, bulk density, and soil carbon.

    An integrative approach for introducing conservation agricultural practices to tribal societies in India
    Halbrendt, Jacqueline; Lai, Cynthia; Chan-Halbrendt, Catherine; Idol, Travis; Ray, Chittaranjan; Evensen, Carl; Roul, Pravat K. (Honolulu Hawaii: University of Hawaii, Department of Natural Resources and Environmental Management, 2011)
    Small-holder farms in rural India struggle with reduced maize yields due to traditional farming methods. The introduction of modern conservation agriculture practices can provide higher yields and household income while boosting soil productivity. This poster abstract presents the results of CAPS implementation on experimental plots in tribal villages located in the Indian state of Odessa.

    Halbrendt, Jacqueline; Lai, Cynthia; Chan-Halbrendt, Catherine; Idol, Travis; Ray, Chittaranjan; Evensen, Carl; Roul, Pravat K. (2011)
    This poster introduces the Long Term Research Activity (LTRA) 11, a research activity within the SANREM CRSP program during Phase IV. The objectives of this LTRA are to introduce and promote Conservation Agriculture practices at the tribal and household level in Odisha, India, and monitor the economic, environmental, and social impacts.
