Transitional pathways towards input reduction on French field crop farms

Abstract: Reducing the use of pesticides and fertilizers in agriculture has become a key issue in many European countries. How have farmers engaged in this type of process modified their practices and in what respect can this help to design pathways for reducing the use of inputs? To answer this question, we developed a methodology for analysing farmers' trajectories, tracing the dynamics of change towards reduced use of inputs (fertilizers and pesticides) throughout a farmer's career, based on the notion of agronomic-coherence phases (input intensive, rationalized, integrated crop management for one crop, for several crops, integrated production and organic farming). Applying this framework to a sample of 20 field crop farmers in Champagne Berrichonne (Indre, France) allowed us to identify three main types of transitional pathway. These pathways differ with regard to the sequence of the different agronomic-coherence phases, and to performance in terms of input use during the last phase. We also identified key transitional practices which play a pivotal role in the transition from one phase to another. We discuss the role of learning features in the path dependency. In terms of agricultural sustainability, this study contributes to agricultural extension and to the design of transitional pathways towards less input-dependent cropping systems.

Organic farming in India: a vision towards a healthy nation

Abstract: Food quality and safety are the two important factors that have gained ever-increasing attention in general consumers. Conventionally grown foods have immense adverse health effects due to the presence of higher pesticide residue, more nitrate, heavy metals, hormones, antibiotic residue, and also genetically modified organisms. Moreover, conventionally grown foods are less nutritious and contain lesser amounts of protective antioxidants. In the quest for safer food, the demand for organically grown foods has increased during the last decades due to their probable health benefits and food safety concerns. Organic food production is defined as cultivation without the application of chemical fertilizers and synthetic pesticides or genetically modified organisms, growth hormones, and antibiotics. The popularity of organically grown foods is increasing day by day owing to their nutritional and health benefits. Organic farming also protects the environment and has a greater socio-economic impact on a nation. India is a country that is bestowed with indigenous skills and potentiality for growth in organic agriculture. Although India was far behind in the adoption of organic farming due to several reasons, presently it has achieved rapid growth in organic agriculture and now becomes one of the largest organic producers in the world. Therefore, organic farming has a great impact on the health of a nation like India by ensuring sustainable development.

Food security of small holding farmers: comparing organic and conventional systems in India

Abstract: This study compared farm production, crop yield, input cost, and income in organic and conventional farming systems in three states of India: Uttarakhand, Madhya Pradesh, and Tamil Nadu. The results showed that organic farming reduced the input cost without affecting the net margin in all three states. Total food production was found to be comparable for the two systems in two of three states. While yield of rice and wheat generally was lower under the organic systems, yield from intercropping food crops was generally higher. The number of agro-ecological methods and percentage of farms practicing different agro-ecological methods were higher under organic systems than conventional systems. These results suggest that organic farming has the potential to improve food security of small farmers by reducing indebtedness due to the lower cost of production without affecting total farm production and farm income.

Elucidating the apparent maize tolerance to weed competition in long-term organically managed systems

Abstract: In a long-term cropping systems trial comparing organically and conventionally managed systems, organic maize production sustained crop yields equal to conventional methods despite higher weed levels. In 2005 and 2006, an experiment nested within the trial was conducted to gain insight into this apparent crop tolerance to weed competition. Density of mixed weed species was experimentally manipulated to achieve a broad range of weed infestation levels. Under standard management conditions, all cropping systems produced equivalent maize yields, even though weedy plant biomass in the organic treatments was between fourfold and sevenfold greater than in the conventionally managed maize. Increased yield capacity, evidenced when plots were maintained weed-free, and enhanced crop competitiveness, were the main pillars of this apparent crop tolerance to weed competition in the organic systems. Increased soil resource availability and a faster relative crop growth rate in the organic systems probably contributed to these factors, which play an important role in buffering crop fitness during years of less than ideal weed control. Simultaneously, the experiment illustrated the poor efficacy of mechanical weed management in the organic systems, which is the main reason organic maize did not out-yield conventional maize under standard management conditions
