Abstract

A field experiment was conducted at the farm of Tamil Nadu Agricultural University, Coimbatore during kharif season (Spring) to study the effect of eco-friendly management practices on quality characteristics of transplanted lowland rice. Rice CO(R) 48 was used as a test variety. The experiment was laid out in randomized block design (RBD) with three replications and nine treatments which are T1 –100 % N through dhaincha + balance P and K through inorganic fertilizers, T2 – 50 % N through dhaincha + balance N, P and K through inorganic fertilizers, T3 –100 % N through vermicompost + balance P & K through inorganic fertilizers, T4 –50 % N through vermicompost + balance N, P and K through inorganic fertilizers, T5 –100 % NPK (150 : 50 : 50 kg ha-1) through inorganic fertilizers, T6 –100 % NPK through inorganic fertilizers + 12.5 t farmyard manure, T7 – 100 % NPK through inorganic fertilizers + 6.25 t dhaincha, T8 – 100 % NPK through inorganic fertilizers + 5 t vermicompost, T9 – Control. The results revealed that higher quality characteristics of rice including physical parameters (grain length, grain breadth and L/B ratio), chemical parameters (moisture, protein, carbohydrate, amylose, fat and fibre) and cooking quality were obtained with application of 100 % N through dhaincha + balance P & K through inorganic fertilizers followed by application of 100 % NPK through inorganic fertilizers + 6.25 t dhaincha and it was par with application of 100 per cent NPK through inorganic fertilizers + 5 t ha-1 vermicompost and 100 per cent NPK through inorganic fertilizers + 12.5 t farmyard manure. Lower quality characteristics of rice were registered in absolute control.

Keywords: Dhaincha, FYM, rice, quality characteristic and vermicompost.
