Response of winter rice (Oryza sativa) t~~nitrogen, phosphorus and potassium fertilization on Godavari Alluvials

Abstract

A field experiment was carried out with ha) and P,O, (0, 40 and 80 kgha) and 2 rice (Oryza sativa L.) during the winter levels of K,O (0 and 40 kglha), replicated 4 seasons of 1987--88 and 1988--89 at times. Three additional treatments (absolute Maruteru. The soil was clay loam (Vertic control, No Po KJ were also included in each chromusterts) of medium fertility (organic replication. Seedlings of 25 days (IR 64) carbon 0.58%, available P 18 kglha, were transplanted at a spacing of 15 cm x 15 available K 30kgha) with pH 6.9. The trial cm on 9 and 10 December respectiveIy in was laid out in a partially confounded design both the years and harvested on 28 March. with 3 levels each of N (40, 80 and 120 kg1 One-third of N and entire dose of P and K Table 1.
