Determination of growth and yield performance of various spring planted sunflower (Helianthus annuus L.) hybrids under agro-ecological conditions of Sargodha,Pakistan.
An experiment was conducted at the research area of University College of Agriculture, University of Sargodha during spring season of 2010 to study the growth and yield performance of various sunflower hybrids (Hysun-33, Hysun-38, S-278, SF-187, Pioneer64A93FH-314 and FH-337). Randomized Complete Block Design (RCBD) was used, having four replications; with each subplot of size 2.60x6 m.Thc results indicated that hybrids differed significantly in all studied traits except days to emergence and number of plants m-2. Days taken to flower completion and to maturity of crp were more in hybrids Hysun-38, Hysun33, where as Hybrids FH-337 and S-278 completed their flowering and reached to maturity in minimum number of days. Taller plants were attained by plots sown with hybrids Hysun-33 and Hysun-38, whereas dwarf plants were observed in SF-187 and S-278.Maximum head diameter was found in S-278which was statistically significant than rest of the hybrids. Highest number of achenes head1 and 1000- achene;s weight was noted by Hybrids S-278 and Hysun-33while hybrid FH337 gave minimum number of achenes head1 and lowest 1000-achenes weight Significant variation was also observed in achenes yield among the various hybrids under study. Maximum grain yield was produced by hybrid S-278(2735kg ha1) followed by hybrid Hysun-33 (2542 kg ha1) while Hybrid FH-337 showed minimum achenes yield (1650kg ha-1). Significant increase of 65％ was observed in the achenes yield ha of hybrid S-278 when compared with hybrid FH-337.lt is concluded that the hybrids S-278 and Hysun-33 showed high yield and were best adapted to the climatic conditions of Sargodha.
