This study is very essential based on the study area, so I have frame some objective like to ascertain the reasons for shifting from inorganic to organic cultivation, to study the type, pattern and levels of use of manures, fertilizers and plant protection measures and the cost involved under both the type of farming, to compare the yield, market prices and returns of organic products with that of inorganic products, to enumerate the problems of organic product growers.
economies and facilitate their integration into national economies. For example, there will always be locations where certain crops cannot be grown sustainably or economically using the current range of organic methods. 0000046496 00000 n
We have compiled knowledge about how things grow and why some growing methods might be preferred over other methods.
The organic crop rotation reaches about 57% (8.3 Mg ha−1 yr−1) of the DM yield, about 66% (163 kg ha−1 yr−1) of the N removal and roughly 56% (3741 kg ha−1 yr−1) of the C fixation of the conventional crop rotation. © 1997 SCIThe importance of nitrogen (N), weeds, and water as yield-limiting factors was evaluated over a 4-year period in tomato cropping systems under conventional, low-input, and organic management.
123 pp. The model has been applied in the experimental farm Scheyern in southern Germany, which had been divided into an organic (org) and a conventional (con) farming system in 1992. sequence (Dobbs and Smolik, 1996; Drinkwater et al., 1998; Edwards, 2007).
productivity and nitrogen balance across agroecosystems do not account
National Program on Organic Production (NPOP), India described Organic Farming that “Organic Farming is a system of farm design and management to create an eco-system which can achieve sustainable productivity without the use of artificial external inputs such as chemical fertilizers and pesticides.” level of protection of human, animal and plant life and health is not being India is an agrarian country.
The model couples the balancing of C, N and energy fluxes with the target to estimate the climate-relevant CO2, CH4 and N2O sources and sinks of farming systems.

In another definition Food and Agriculture Organization (FAO) suggested the following: “Organic agriculture is a unique production management system which promotes and enhances agro-ecosystem health, including biodiversity, biological cycles and soil biological activity, and this is accomplished by using on-farm agronomic, biological and mechanical methods in exclusion of all synthetic off-farm inputs”.

In Scheyern, C sequestration has set in under organic management (+0.37 Mg ha−1 yr−1), while humus depletion has been recorded in the conventional system (−0.25 Mg ha−1 yr−1).Greenhouse gas emissions (GGEs) due to fuel consumption and the use of machines are nearly on the same level in both crop rotations.
I am using only diploid annual Helianthus wild species for diversification As per the definition of the United States Department of Agriculture (USDA) study team on organic farming is as follows: “organic farming is a system which avoids or largely excludes the use of synthetic inputs (such as fertilizers, pesticides, hormones, feed additives etc.)
The results were converted into CO2 equivalents using its specific global warming potential (GWP). The traditional Ladakh agriculture is unique and representative of Himalayan agriculture and its conservation of old land races of cultivated plants, especially of barley and alfalfa, is of global importance. groundwater over a 5-year period (Drinkwater et al., 1998). Performance measures including the numbers of fruit, branches, leaves, plant height, days to first flowering and days to 50% flowering at 20.00, 17.67, 176.33, 73.33 cm, 70.43 and 78.00 were all better (higher or lower) in treated tomato plants than untreated set.
and nitrogen cycling,.
principles for organic agriculture there, because the organic movements have not previously decided to formulate such a set of principles (there are some recent examples though, which we will present below).

The objectives of environmental, social, and economic sustainability are the fundamentals of organic farming (Stockdale et al.). Crop production with the use of alternative sources of nutrients such as crop rotation, residue management, organic manures …
promotes and enhances biodiversity, biological cycles and agro-ecosystem health.organically farmed land in the USA, which is just 0.23%.
Nutritional studies in humans and experiments which used holistic methods of analysis are also included. Results indicated that N availability was most important in limiting yields in the organic system and water availability was more important under conventional management. Organic systems explained 1.1 The principles of organic farming Organic farming is underpinned by a set of guiding principles, drawn up by the International Federation of Organic Agricultural Movements (IFOAM). unimportant. 0000002787 00000 n
