Agriculture Systems

Since the conservation agriculture (CA) is spreading across the globe, information on weed dynamics and their management under CA is needed. Here, an attempt has been made to summarize the recent research on weed dynamics and their management aspects in the CA systems. Changes in patterns of tillage, planting systems, and other management strategies can alter the soil environment and lead to shifts in weed populations. Weed patterns and populations are not always stable but vary with location, crop, and herbicides use. However, in many long-term conservation management studies, a general increase in perennial weeds and grass species has been observed. No tillage increased the weed population during first season and there after decreased. Residue has significantly reduced the number of weed species and population compared to conventional agriculture systems. The development of low-dose of non-selective pre and selective post emergence herbicides, and transgenic crops has greatly improved the feasibility of CA systems.DOI: http://dx.doi.org/10.3126/ije.v3i4.11733 International Journal of Environment Volume-3, Issue-4, Sep-Nov 2014Page: 91-100

Abstract Conservation Agriculture (CA)-based Sustainable Intensification (CASI) practices in this study comprised minimum soil disturbance, permanent soil cover, intercropping of maize and legumes, and use of improved crop genotypes and fertilizers, and were tested on-farm in different agroecologies in northern and eastern Tanzania. The results for six consecutive years of study indicate increased adoption of CASI practices compared to the baseline year (2010). The major impacts of these practices were reduced production costs, labour savings and overall increased crop and land productivity. The average area allocated to improved maize-legume (ML) intercrop rose during the project period by 5.28 ha per household, of which 15% was under complete CASI practices. Adoption trends show that, on average, 6.5% of adopters across the study and spillover communities started adoption in the 2nd year and about 14% of farmers adopted the practices over the next 3-5 years. Demographic and human capital (family size, education, age and farming experience), on-farm CASI demonstrations, farmer to farmer exchange visits, social capital (farmers' group or a cooperative), access to input and output markets (improved seeds, herbicides, fertilizers, insecticides and equipment) and food security were found to have positive and significant effects on adoption of a range of CASI practices. These results suggest continued and long-term efforts in investments in demonstrations, institutionalizing CASI practices in NARS, and good links to input and output markets, including appropriate machinery, are necessary to achieve sustained adoption.

Abstract The Conservation Agriculture (CA) system promoted by Total LandCare (TLC) and the International Maize and Wheat Improvement Center (CIMMYT) is based on 14 years of experience grounded on the principles of minimum soil disturbance, good soil cover and crop associations. The platform to promote CA in Malawi was to build a strong base of knowledge about best practices through an innovative non-linear research-extension approach. Long-term on-farm trials were conducted in multiple sites across Malawi to compare yields and labour inputs of CA with conventional ridge tillage on the same footing. Results showed the superiority of CA in terms of maize and legume yields with significant savings in labour and resilience to climate change. The results provided the basis to upscale CA although adoption was lower than expected. Key challenges included: (i) lack of exposure and training; (ii) conflicting extension messages; (iii) misconceptions about inputs and tools for CA; (iv) resistance to change unless CA is clearly seen to be a better practice; (v) fears about controlling weeds, pests and diseases under CA; and (vi) perceptions that increased termites and earthworms are harmful to soils and crops.

Given the potential of long term intervention to positively influence speech/language and psychosocial domains, a treatment protocol was developed at the Stroke Comeback Center which addresses communication impairments arising from chronic aphasia. This article presents the details of this program including the group purposes and principles, the use of technology in groups, and the applicability of a group program across multiple treatment settings.
