  Four cultivars of garlic namely, G.S-1, Lehson Ghulabi, Chinese and Italian (local and exotic) were evaluated for yield and yield components during 2000-2001. The cultivar “Italian” took significantly longer time (216 days) to reach 50% neckfall than rest of cultivars which took 179 to 199 days. The average bulb weight in cv. Chinese was significantly higher than rest of cultivars which ranged from 27-35g. The cultivar “Chinese” was found to be high yielding with 11.6 tones bulb yield per hectare which was 3.4, 2.3 and 1.6 times higher than G.S-1, Italian and Lehson Ghulabi, respectively.

  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.

  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.

  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.

  Population dynamic of leaf hopper (Amrasca biguttula biguttula) on brinjal crop and effect of abiotic factors on its dynamic were studied. The leaf hopper started the activity soon after transplanting. The serious activity was noticed from 21st May to 6th August. The highest leaf hopper number per leaf was found as 12.96 + 0.93 on 9.7.96. Mean maximum and minimum temperature were found as positively and significantly correlated with population change. Relative humidity and rainfall was found as negatively and non-significantly correlated with population fluctuation. Sunshine was also positively but non significant correlated factor.

  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).
