Abstract
A field experiment was eondueted to study the response of uharif pop sorghum
genotypes to FYM and mineral fertilizers in black soil under rainfed conditions at Main
Research Station, Dharwad during rainy season of 2000. The experiment was laid out in
randomized block design with 15 treatments.
Application of RDF (80 : 40 : 40 kg N : : Kp ha-1) + FYM (5 t ha-1) to
the genotype Inamhongal -1 has recorded higher leaf area and LAI at 120 DAS (48.60
dmVplant and 5.40, respectively). Higher total dry matter (TDM) production (184.65 g/
plant) was recorded at harvest with RDF + FYM application. Higher dry matter
accumulation in leaves (42.10 9/plant), stem (88.86 g/plant) and ear (69.1 g/plant) was
recorded at 120 DAS with the RDF + FYM treatment. Highest peduncle length was
noticed with the Inemhongal-lboth at 120 DAS and at harvest (21.8 and 31.5 em,
respectively).
Inamhongal-1 has recorded higher ear head length and girth (27.7 and 12.4
em, respectively). Grain number per ear head was higher with application of RDF +
FYM to Inamhongal-1 genotype (1432.3). Grain weight per plant, test weight and number
of raehes per ear head were higher with the genotype Inamhongal-1. Grain yield was
higher (1356 kg/ha) with Inamhongal-1 and was lower with Uppinbetageri-1 (910 kg/
ha). Stover yield was also higher with Inamhongal-1 (24.5 t/ha) but was lower with
Gadag-1 (9.5 t/ha). Gadag-1 genotype has recorded higher 111 (0.107), maximum protein
per cent in grains (7.55) and higher uptake of N,P and K (116.2, 25.1 and 154.3 kg/ha,
respectively). Combined application of RDF + FYM recorded higher available N, P2O5,
KjO and organic carbon at harvest (156.62,26.27,265.65 and 0.617, respectively) in the
soil.
Application of 50% RDF + FYM recorded higher popping percentage,
expansion volume of pop and flake size (78.00, 17.89 ml/g and 0.44 ml, respectively).
Protein per cent in pop was higher with lnomhongal-1 (7.40). Net returns were higher
with Inamhongal-1 holh in case ol giains and pops (Rs. 21063/ha and Rs. 30463 /ha,
respectively) with the application of RDF + FYM.
