Abstract
The paper explains possible outcomes in physical parameters of sunflower growth when irrigated by foliar spray of different concentrations of lemongrass aqueous leaf extract. Germination period begins from 48th hour and lasts up to 72nd hour in which vigor seems to be highest in 1% samples. The observed average time period employed by seeds to germinate and the vigor of the treated seeds show significantly (p<0.1 and p<0.05 respectively) different pattern in the early period of germination than the later hours. Seedling growth is determined indicating highest growth in 0.5% and 1% samples in all evaluated parameters. After seedling establishment, plants gained maturity where potential of growth is weakly significant (p<0.1), relatively greater in 0.5% and 1% samples as indicated in their growth parameters i.e., root/shoot length, root/shoot dry weight and shoot length/leaf area. Growth correlation slightly declines in 2% and 3% samples. Lemon grass treatment found effective for germination and growth of sunflower plants in lower concentration hence can be utilized for better yield of sunflower crops and capable to minimize the use of other hazardous chemical fertilizers.
