ABSTRACT
A pot culture experiment was conducted at green house, Department of Soil Science and Agricultural Chemistry, Agricultural College, Bapatla during 2013-2014 to study the influence of aquatic weed composts (Ipomoea and Eichhornia) and FYM with various levels of fertilizers nitrogen on yield and nutrient uptake of rice. The results revealed that application of 75 per cent RDFN + 25 per cent substitution of nitrogen through aquatic weed composts resulted significantly higher drymatter production, grain and straw yields and uptake of macro and micronutrients by rice over application of 160 kg N ha-1 through urea alone (T1- 100% RDFN).
Key words :
Eichhornia compost, FYM, Grain yield, Ipomoea compost, Nutrient uptake.
