  Observation on number of leaf hoppers per leaf of different cultivars of brinjal crop was recorded. The cultivars Purple long, Nepali and Neelum were found quite resistant to leaf hopper. The varieties Sigatoka beauty and Sitara were found as moderately susceptible while Chayat, Greek, Local Gool, Violetta, Sciliana, Prospara and Violetta lunga were found to be the most susceptible cultivars. The variety Purple long had minimum mean leaf hoppers per leaf and gave highest yield than other cultivars. Although the variety local gool was found most susceptible yet gave yield at par with resistant cultivars like Nepali and Neelum.

  Twenty three exotic and one local cultivar of chillies were tested in an observational trial during 1998. Out of these 9 selected cultivars/lines PBC-581, PP 9656-15, BS-96, MI-2, PBC-534, Korean, PBC-386, PP 9656-6, and NARC-IV were further evaluated for yield, green and red fruit characteristic in a replicated trial during 2000. PBC-581 (17.33 t/ha) and PP9656-15 (16.04 t/ha) gave highest green fruit yield followed by BS-96 and MI-2 whereas, the local cultivar NARC IV produced the lowest yield (3.68 t/ha). Data regarding fruit size, color, position, bearing habit and pungency were also recorded. Maximum weight loss due to drying of red chilli fruit was observed in BS-96, whereas the lowest weight loss (68.72%) was recorded in cv. Korean.

  Eight pea cultivars namely, lincoln, napolitano, piccolo, P. alberto, caravella, rondo, S. gennaro and climax were evaluated for their performance with regard to seed yield. Cultivar rando produced the maximum number of pods (18.8), while caravella produced the minimum number of pods (8.8) per plant. The maximum 1000-seed weight was recorded in S. gennaro (319.0 g) followed by caravella (286.3 g), piccolo (274.3 g) and napolitano (271.7 g). The seed yield in various cultivars ranged from 1.43 to 1.91.

  The effects of seedling/set size and planting times on bulb yield and quality in onion cultivar Phulkara were studied during autumn season 2000. The bulbs of seedlings and sets were graded in three sizes of 2.5, 3.5 and 4.5 mm diameter and 7.5, 12.5 and 17.5 mm diameter, respectively and were sown on 15th August and Ist September, 2000. Highest mean marketable bulb yield (21.2 tha-1) was obtained using 17.5 mm diameter size sets and seedling with 4.5 mm diameter bulbs. However, the crop sown with 17.5 mm diameter sets on 1st September, produced significantly highest marketable bulb yield of 24.6 tha-1 and also gave highest percentage of doubles (17.9 %). Sets with 17.5 mm diameter though produced highest percentage of doubles but also gave highest marketable bulb yield and are therefore recommended for planting autumn season crop in first week of September.

  An experiment was designed to study the morphological and yield behavior of nine exotic and one local cultivar of tomato under Islamabad conditions. Characters studied were time required to flowering, fruit setting, fruit ripening, yield/plant and yield ha-1. Significant difference in the parameters except days to maturity were observed which could be attributed to inherited differences among cultivars. Cultivar marmande (TMV) took significantly minimum time (65.0 days) to ripen followed by S. marzano which ripened in 72.3 days. Cultivar polefemo ripened late (91.7 days) followed by marmande which took 88.7 days to ripen. Cultivars marmande TMV and marmande out yielded other cultivars with 64.29 and 62.99 t ha-1, respectively while poor yield was obtained in S. marzano (14.90 t ha-1).

  Efficacy of two weedicides at recommended rate i.e., pendimethalin (liter ha -1) and oxadiazon (0.8 liter ha -1) was tested and compared with weed free (manual hoeing) and weedy control. Single application of any of above weedicide was not sufficient to obtain yield equal to weed free treatment. Application of pendimethalin and oxadiazon were effective in controlling weeds initially for 80-90 days. Highest bulb yield (10 ha -1) was found in weed free treatment followed by oxadiazon (5.293 ha -1), pendimethalin (4.043 ha -1). Lowest bulb yield was found in weedy control.

  The study was conducted to examine the effect of set size on bolting, bulb yield and quality in onion cultivar ‘Phulkara’ during autumn season 2001. Highest percentage of bolting (31.1 %) and doubles (69.4 %) was recorded in large sets of 29 mm diameter. In large size sets (29 mm diameter) bulbs matured in minimum time (134.5 days). Highest marketable bulb yield (26 t ha-1) was obtained with 17 mm diameter set followed by 20 and 23 mm diameter yielding 22.9 and 20.0 t ha-1, respectively. Large size sets (26 and 29 mm diameter) produced significantly higher un-marketable bulb yield of 13.9 and 14.9 t ha-1, respectively.

  The performance of eight tomato hybrids was studied under plastic tunnel for number of days to flowering and maturity, number and weight of fruit per plant, single fruit weight and yield. The sequential pickings in tomato hybrids started in second week of December 1991 and finished in the last week of March 1992. The cultivars parana and turquesa matured earlier taking 95.25 and 98.75 days, respectively. The cultivar turquesa with maximum fruit weight plant-1 exhibited the highest yield of 20.45 kg m-2 followed by fortara, royesta and jacinto yielding 19.55, 18.92 and 18.30 kg m-2, 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.

  Seven exotic chilli (Capsicum frutescens) cultivars, NARC-4, 9656-06, 9656-15, PBC-386, PBC-534, PBC-581 and Korean were evaluated for different yield parameters including number of fruits per plant, fruit weight per plant, single fruit weight, fruit size and yield per hectare. A potential line PBC-386 was found the highest yielding with 14.5 t ha-1 of fresh fruit. It was followed by PBC-534 and 9656-15 yielding 11.9 and 10.1 t ha-1, respectively while Korean seemed to be the poorest yielder with only 4.2 t ha-1 of fresh fruit.
