A field experiment was conducted at the experimental farm, College of Agriculture, Abu-Ghraib, Baghdad, Iraq during the period from mid. of March 2012 to mid. of July 2014 to investigate the effects of plant growth regulators and foliar application stages on ovules abortion, seed set and its germination of two alfalfa cultivars. Layout of the experiment was R.C.B.D. arranged in split-split plot with three replications. Cultivars (local and hamedan) were assigned as a main plot and foliar application stages (vegetative growth, flower buds emergence, 50% flowering and 80% flowering) were assigned as sub-plots, while growth regulators (Alar, Ethephon, Naphthalene acetic acid(NAA) and control treatment) were assigned in the sub-sub-plots. Result showed that there were no significant differences between cultivars in all traits. Foliar application of NAA increased No. of ovules per floret (9.11) compare with other treatments, but it was not significantly different compare with Alar. In 1st and 2nd seed crop, plants sprayed with Alar at flower buds emergence stage gave highest seed set (5.17, 6.93) respectively. Percentage of ovules abortion significantly influenced by growth regulaters, folair application stages and their interaction. Since, foliar application of Alar at beginning of flower buds emergence reduce % of ovules abortion (30.89). In general, plants sprayed at vegetation growth stage increased % of seed germination. It was clear from this study that more than 40% of ovules were aborted, this may be one of the reasons for reduction of seed yield in alfalfa, therefore, we recommended to do more researches in this field in order to know the causes of ovules abortion.

A field study was conducted at the experimental farm, College of Agriculture, Abu-Ghraib, Baghdad, Iraq during the period from mid. of March 2012 to mid. of July 2014 to investigate the effects of plant growth regulators and foliar application stages on seed yield and it’s components of two alfalfa cultivars. Layout of the experiment was R.C.B.D. arranged in split-split plot with three replications. Cultivars (local and hamedan) were assigned as a main plot and foliar application stages (vegetative growth, flower buds emergence, 50% flowering and 80% flowering) were assigned as sub-plots, while growth regulators (Alar, Ethephon, Naphthalene acetic acid (NAA) and control treatment) were assigned in the sub-sub-plots. Result showed that there were no significant differences between local cult. and c.v Hamadan in seed yield and it’s components except 1000 seed weight. Foliar application of growth regulators at flower buds emergence significantly increased No. of racemes per stem and No. of seed per pod, therefore it produced highest seed yield (450 kg/ha) as a mean of two seasons. In 1st seed crop, there were significant interaction between cultivars and foliar application stages on seed yield since local cult. gave highest seed yield (479.6 Kg/ha) when it spraying at flower buds emergence stage with an increasment 14.5% compare with hamedan C.V. foliar application alar significantly increased No. of seeds per pod and seed yield in both season , but it was not significantly different than NAA. Since, increasment in seed yield compare with ethephon and control treatment reach (25.4, 18.3), (18.8, 17.7) in 1st and 2nd seed crop respectively. as average for two seasons, higher seed yield (565 Kg/ha) can be obtained from sowing local cultivar and foliar application of alar when the stand reaches at flower buds emergence stage.

Standardization of the crop regulation practices is vital for spike and corm yield maximization in gladiolus (Gladiolus hybrids Hort.). Hence, a field experiment was conducted in factorial randomized block design with three replications at Annamalai University, Annamalai Nagar, during 2019 with the objective to maximize the spike and corm yield of gladiolus by growth regulators and leaf regulation practices done after spike harvest. The gladiolus cv. Sarala was tested with 15 treatment combinations comprising growth regulator treatments of corms viz., 100ppm GA3(G1), 150ppm GA3(G2), 100ppm IAA(G3), 150ppm IAA (G4), and Control(G5)and leaf regulation practicesviz.,harvesting spike leaving all leaves (L1), harvesting spike with three leaves (L2), and clipping leaves at 20cm above the base (L3). The results revealed that the growth regulator treatments, given to corms significantly influenced the growth, flowering, and spike yield of gladiolus. Corm soaking treatment of GA3@150 ppm evinced the best treatment in respect of growth, flowering, and spike yield of gladiolus. Though, the effect of leaf regulation practices on growth and flower yield were insignificant, but their influence in corm yield was significant. The interaction of growth regulator soaking of corms with leaf regulation practices significantly influenced the spike and corm yield. The maximum spike (1.01) and corm yield (1.94) were observed with Corm soaking of GA3@150ppm and harvesting of spikes with three leaves. Leaf regulation by clipping of leaves at 20 cm above the base (L3) had negative influence on corm growth when compared to harvesting of spikes leaving all leaves (L1). The maximum corm diameter (3.25cm) and corm weight (25.4g) were observed with 150 ppm GA3 and harvesting spikes with three leaves. The least corm diameter (2.08cm), number of corms per plant (1.22) and corm weight (17.3g) were recorded with control treatment with cutting leaves at 20cm above the base.
