Ten commonly cultivated cultivars of tomato (Solanum lycopersicum L.) in Nepal were tested in a plastic tunnel and in the field for their susceptibility to Pseudomonas syringae pv. tomato, the causal agent of bacterial speck. Four of the ten cultivars were local and six were hybrids. The leaves of each cultivar were sprayed with P. s. pv. tomato both in the tunnel and in the field. The genotypes exhibited a considerable variation in response to infection, with the disease severity index (DSI) varying from 1.80 to 4.25 in the field and from 1.10 to 4.20 in the tunnel. The cultivars Thims 16, C.L. and Spectra 737 were the least susceptible in the field, with DSI values of 1.80, 2.05 and 2.25, respectively; while in the tunnel all the local cultivars (C.L., Panjabi, B.L. and Lapsi Gede) showed very low susceptibility, with respective DSI values of 1.10, 1.20, 1.65 and 2.30. In the field, the most susceptible cultivar was Lapsi Gede (DSI=4.25) and in the tunnel the most susceptible was NS-719 (DSI= 4.20). Source

Human urine, rich in plant nutrients, is a readily available fertilizer but limited information is available about the best use of human urine in crop production. A field experiment was carried out in Kathmandu, Nepal during the year 2011 to evaluate the fertilizer value of human urine in different combination and compare the value with compost, urea and their combinations based on plant performance. The experiment was laid out in Randomized complete block design (RCBD) consisting of eight treatments with three replications. Each treatment was fixed to a supply of 100kgNha-1. California Wonder, a popular open pollinated sweet pepper (Capsicum annuum L.) variety was selected as an experimental crop. The highest plant height (54.7cm), number of fruits per plant (9.1), and fruit yield per plant (553.9gplant-1) were recorded with the plants fertilized with human urine in combination with compost. Human urine supplemented with 50kgPKha-1 gave highest fruit weight (67.2g) and fruit diameter (5.5cm). Plants fertilized with the combination of human urine and compost showed better growth and yield compared to the application of fertilizer sources alone. The results indicated that the human urine performs better when used in combination with compost, and can be used as a promising fertilizer source in sweet pepper production. © 2013 Elsevier B.V.

Several surveys were carried out during three consecutive years (2007-2009) on the major crops cultivated in different districts of Nepal, in order to verify the possible presence of diseases caused by bacteria. The monitoring was carried out twice a year, in spring and autumn. During the survey we observed a wide range of bacterial diseases of plants. Most of the diseases were observed for the first time while others had been reported previously. Among the bacterial diseases observed for the first time, the most important were olive knot, bacterial speck of tomato, crown gall of plum, soft rot of potato, bacterial spot of tomato, and bacterial spot of cucurbits. Outbreaks of black rot were observed in different Brassica fields. Among the other widespread diseases, the most important were bacterial leaf blight of rice, citrus canker, citrus greening, bacterial wilt of tomato, potato, pepper, and eggplant, halo blight of bean, and bacterial pustule and bacterial blight of soybean. Attempts to explore the source of introduction of these pathogens, their spread, and yield losses caused were made together with recommendations for control measures. Source
