SUMMARYIn the Kathmandu valley of Nepal radish (Raphanus sativus) plants had an average often branches, each with 155.2 ± 18.3 flowers, 14.1 ± 1.3 mm in diameter. Flowers opened in the morning and remained open for two to three days. Flowering began in the first week of March and lasted for one month. Apis cerana workers foraged on radish plants for 11.5 hours each day, from 06.40 h (26 min after sunrise) to 18.30 h (18 min after sunset) with peak foraging between 11.00 h and 14.00 h. At 09.00, 12.00 and 15.00 h respectively, workers averaged 4.3, 5.3 and 12.8 s per flower, visited 8.0, 9.0 and 5.0 flowers per minute and collected 11, 10 and 7 mg of pollen. Most workers collected either pollen or nectar, but 4–7% collected both nectar and pollen during the same foraging trip. Pod set, number of seeds per pod, seed weight and germination for radish plants caged with an A. cerana colony were 45%, 42%, 45% and 73% greater, respectively, than for open-pollinated plants. Plants with insect visitors excluded ha...

SUMMARYIn the Kathmandu valley of Nepal, cauliflower (Brassica oleracea var. botrytis) and cabbage (Brassica oleracea var. capitata) plants had averages of 7 branches with 600 flowers and 12 branches with 94 flowers, respectively. Flower diameter was 14.9 mm in cauliflower and 13.8 mm in cabbage. The yellow flowers of both crops opened in the morning and remained open for two to three days; the total flowering period of each crop lasted for about one month, with cauliflower beginning in mid-February and cabbage in mid-March. Apis cerana colonies were caged individually with plants of the target crops. Bees started foraging on cauliflower and cabbage at c. 07.00 h and 06.30 h, respectively, and ceased flight activity at c. 18.00 h and 18.30 h, respectively. Foraging on cauliflower started at ambient temperatures of 7°C. Peak foraging activity was between 11.00 h and 13.00 h for each crop. The duration of individual foraging trips was 26.9 min for cauliflower and 23.9 min for cabbage. Visits to individual f...

Women account for more than 70% of the world's poor and many depend on subsistence agriculture and forest products for their livelihoods. However, they are facing difficulties to access markets and obtain a fair share of the value of the products they collect or produce. In Nepal, the level of inequality has risen among lower caste people and women despite an overall decline in poverty. Making market information available to both men and women, building alliances for collective bargaining with traders, and strengthening linkages with external service providers are the key elements in the paper impacting to increase income of women; women's empowerment through changes in traditional gender roles; and social capital. The paper identifies challenges to the institutionalisation of this approach, which is needed to maintain functional alliances and linkages among the producers, traders, and processing companies, and to increase women's control over the productive resources.

Agriculture is the main source of livelihoods for a majority of population living in the rural areas of the Hindu KushHimalayan (HKH) region. While two per cent of its rural population depends entirely on agriculture, a large majority i.e., 91 percent depend on it for making 30-50 per cent of their livelihoods. The agricultural land resources in mountain areas are limited and landholding size is small. About 90 percent of the faming households cultivate less than one hectare of land each. Moreover agricultural land resources in many areas are marginal in productivity. Therefore, many farming households in mountain areas are not able to produce enough food to ensure year round food security for their families.

Apple orchards are one of the major attractions in hills and contribute to farmer's economy. However, due to climatic variations and poor pollination, quantitative and qualitative production is still not been achieved. Research has indicated that honey bees are significant pollinators for temperate fruit crops by influencing fruit setting pattern and reducing premature fruit drop. For assessing the value of pollination services in apple orchards through Apis cerana, specific study has been undertaken in two different orchards in Nainital district of Uttarakhand. The comparative study has been made which revealed that the fruit setting was significantly higher in orchard having pollination services from bees than control site where the pollination was dependent on available natural pollinators. These studies suggested that for enhancing the productivity and improving the quality of apple fruits, pollination services through bees is of significant value.
