Abstract
The Permanent manurial trial (PMT) in rice was established at RARS Pattambi in 1972 and is being conducted continuously in the same field with eight treatments of varying nutrient management options. The objective of the experiment was to study the effect of long term application of fertilizers and manures on growth and yield of the plant and monitoring of soil quality. The PMT experiment with 44 years of cropping history revealed the superiority of integrated nutrient management with 50 Per cent NPK along with 50% FYM over the sole use of fertilizers. The use of fertilizers alone or ammonium sulphate alone did not produce sustainable yields in the long run indicating the need for balanced application of nutrients and integration of organic and inorganic sources of plant nutrients for sustainable yields.
