Tillage and nutrient management as quality improver in fodder oat under oat-paddy cropping system.

A field experiment was conducted at forage field situated at College of Veterinary Science and Animal Husbandry, campus of BAU Ranchi (Jharkhand) to study the effect of tillage and nutrient management on oat- paddy cropping system during 2011 and 2012. It is clear from the graph that the content of N (at second cut) and B (at both the cuts) in forage oat were maximum under conventional tillage. Ca and Fe content were higher under zero tillage. Contents of P and K under conventional tillage were significantly higher compared to minimal and zero tillage. Uptake of N, P, K and Fe by forage oat was significantly higher under conventional tillage as compared to minimal tillage and zero tillage. Crude protein and crude fiber recorded under zero tillage at both the cuts remained at par with conventional tillage but significantly superior to minimal tillage. Further, crude fat and NFE contents under zero tillage were significantly higher compared to minimal as well as conventional tillage. With regards to nutrient levels, 125 % RDF recorded maximum content and uptake of all the nutrients. Nutrient levels negatively responded on crude fat and NFE while, crude protein and crude fiber were positively correlated
