  This study was conducted to assess the influence of season on rooting ability of olive cuttings during the year 2000-2001. Leafy semi-hard wood cuttings were taken from 10 years old olive tree of cultivar "Leccino". The length of cuttings ranged from 10 to 12 cm, with at least 3 to 4 leaves/cutting. The cuttings were collected at fortnightly interval commencing from 15th February to Ist April, 15th July to Ist November and 15th October to Ist December, 2000. The basal portion of the cuttings were treated with talcum powder containing 0.3% Indolebutyric acid (IBA). The treated cuttings were planted in coarse sand in fiber glasshouse under mist. The maximum temperature and relative humidity in fiber glasshouse was 25 to 35 ° C and 75 to 85% respectively. The highest rooting percentage (82%) was obtained in spring season cuttings on 15th February which was significantly higher than those obtained on the other times of the year. The other times of the years showing promise were 15th July and Ist March, where 70 and 65% of rooting was obtained respectively. The cuttings planted on Ist April produced significantly higher number of roots/cutting (13.5) than rest of planting period of the year. The higher plant survival percentage (90 to 93%) was observed in the cuttings planted during 15 Oct to Ist December.

  Eleven advanced lines/cultivars of pea were tested for yield and resistance against powdery mildew under natural conditions of infection. All the lines were found to be resistant while the local cultivars (Climax and PF-400) proved highly susceptible. Significant differences were observed between the yield of local cultivars and those of the advanced lines. Advanced lines out yielded local cultivars. However, the lines 91-1, 91-3 and 91-2 were outstanding with yields of 22.9, 21.6 and 19.6 tones ha-1 respectively.

  Density fluctuation of trapped fruit flies male, Dacu zonatus was studied through out two consecutive years and effect of abiotic factors on its trapping was investigated in peach orchard. Three traps were placed in the peach orchard on Ist September 1995. The trapping of males continued from 8th September to 8th December, 1995. During 1996, the trapping continued from 6th September to 22nd November. No male was trapped from mid of December to end January during 1995-96 and end of November to Ist week of March, 1996-97. From February to April, mean number of males caught per trap was very low. The month of May, June and July were found as the period of high trapping during 1996, while the same was observed in the month of June and July during 1997. All abiotic factors contributed significantly towards increasing/decreasing fruit fly catches. Mean maximum and minimum temperature, rainfall had a positive and highly significant correlation with mean number of males per trap. Mean relative humidity was the only factor, which had a negative and significant correlation.
