Abstract/Description: | Field investigations were made ar the Directorate of Oilseeds Research, Rajendranagar, Hyderabad, during rabi 1995-96 on DSH-130 and on DSH-129 during 1996-1997 and 1998-1999 on alfisols to assess the effect of plant densities (45 x 20 cm, 45 x 30 cm and 45 x 40 cm) and fertilizer levels (recommended dose of 40-40-20 kg NPK/ha, RDF+FYM 5t/ha; 50% RDF+FYM 5t/ha; 150% RDF and 200% RDF) on the certified safflower hybrid seed production in a randomized block design with 3 replications under irrigated situations. it was observed that maximum DSH-129 hybrid seed yield of 1228 kg/ha and 465 kg/ha was obtained in 1996 and 1998, respectively with a spacing of 45 x 30 cm, although the variations between different spacings were not discernible. Likewise spacing did not significantly influence the yield of DSH-130 during 1995-96. Significant interaction between spacing and fertilizer on the yield of pollen parent showed that sowing at 45 x 30 cm in conjunction with application of 200% recommended dose of fertilizer (80-80-40 kg NPK/ha) offerd significantly greater yield than the rest in 1996-97. Application of 200% recommended dose of fertilizer resulted in maximum hybrid seed yield, as well as male parent yield of DSH-129 during both the years, though the variations were not significant. The test weight of hybrid seed was not significantly influenced either by plant densities or fertilizer. |
