The study examines the association between HRM practices and organisational citizenship behaviour (OCB) in Nepalese commercial banks. Quantitative in nature, the study is based on a questionnaire survey method administered on 360 employees sampled from 9 commercial banks: both private and foreign joint venture banks. The OCB level -measured by dimensions of helping behaviour, courtesy and sportsmanship -among the bank employees was found to be at moderate level. No significant variation was found between overall OCBs of managers of both foreign joint venture and private commercial banks. OCB was found to have significant association with the bank employees' ethnicity and length of service, but no association with their gender. The studied HR practices of organisational climate and HR training and development have significantly positive relationship with OCB, while employee empowerment has negative impact on OCB. Out of four HR practices considered for the study, HR training and development was found to be the strongest predictor of OCB.

A field experiment was carried out at research field of Lamjung Campus, Nepal during September 2015 to February 2016 to assess the response of cauliflower (Brassica oleracea L. var. botrytis) to different combination of nitrogenous fertilizer with Azotobacter. 6 treatment with 4 replications were laid out in Randomized Complete Block Design. Phosphorous and potassium was applied full does in all the treatments with chemical fertilizer. It was recorded that the application of recommended doses of nitrogen along with the bio-fertilizer significantly increased morphological characters and yield as compared to other treatments. Besides, the stem diameter was non-significant to the different treatments. It was followed by the full dose of NPK without azotobacter and then 50% nitrogen with azotobacter, which was statistically at par with 25% nitrogen with azotobacter, followed by FYM + Azotobacter. Curd yield along with all the morphological characters were seen lowest in control. Cauliflower curd yield at recommended dose of nitrogen did not significantly differ with the curd yield recorded at half of recommended dose of nitrogen with azotobacter. The finding demonstrated a saving of 50% of nitrogen where it can be substituted with the application of bio-fertilizer to increase the yield and morphological character.
