RESPONSE OF PIGEONPEA GENOTYPES OF DIFFERENT MATURITY DURATION TO RADIATION USE EFFICIENCY UNDER RAINFED CONDITIONS OF ANDHRA PRADESH.

A field experiment was carried out during kharif 2014-15 with 22 medium and 21 mid early duration pigeonpea genotypes on clay soil under rainfed conditions at Regional Agriculture Station, Lam, Guntur. The experiment was laid out in randomized block design replicated thrice to know the response of different duration pigeonpea genotypes to radiation use efficiency (RUE). The results indicated that among medium duration seven genotypes viz., Co6, NTL740, PDKV1942, RVKT 297, AKTM 10-12, LRG151 and GJP1304, among the mid early group six genotypes viz., PRG 200, CRG 140, PT 417-8-2-1-2, PT0012, AKT 12-01 and PRG 305 utilised maximum radiation use efficiency and attained higher yield per ha.see more
