Ethanol, methanol, chloroform, petroleum ether and aqueous extracts of leaves of Parrotia persica were evaluated for antibacterial activity. The zone of inhibition varied from 13 to 22 mm. The highest inhibittion was obtained with methanol and ethanol. Chloroform and petroleum ether extracts did not show any activity. The minimal inhibitory concentration (MIC) value of the methanol extract for the test bacteria ranged between 3.12 and 6.25 mg/ml and that of ethanol extract ranged between 6.25 and 12.5 mg/ml. The results scientifically validate the use of this plant in the traditional medicine of Iran.

A field experiment was conducted at the research farm college of Agriculture, Dapoli (Ma- harashtra) during rabi season of 1982, to study the effect of different levels of N, spacing and intercrops on the growth, yield and quality of sunflower, Cv.Ec 68414. The results revealed that under the prevailing agro-climatic conditions of konkan, a dose of 60 kg.ha'' N was found suitable for sunflower crop during rabi season. Since the response to N was graded and significant, there is scope to increase a dose of N beyond 60 kg.ha. A sunflower crop can be sown at the distance of 30 x 30 cm or 45 x 30 cm. Though the intercrops viz; Indian bean (Dolichos lablab L.) and blackgram (Phaseolus mungo L.) were found compititive with the main crop of sunflower, the total productivity due to these crops was increased substantially.
