In recent times organic farming is attaining popularity among farmers, policymakers as well as researchers. According to the field trials conducted across the globe and of course in India, organic farming is much successful in the case of vegetables, oilseeds, and fruit crops. But in the case of nutrient exhaustive crops like cereals, the yield reduction even after many years of organic farming has been reported by many studies.
Other than the slow nutrient availability, what is the possible reason for the yield reduction in cereals under organic farming?
Hello Amrit,
this is a very interesting technical question of general importance. As an inorganic chemist I'm certainly not an expert in this field, but I do know that organic yields are virtually always lower than conventional yields. For an interesting analysis of this problem, please have a look at the following potentially useful link in whch it is shown that these yield differences are highly contextual, depending both on system and site characteristics:
