It appears in almost all wheat growing areas and causes severe yield loss every year. A study was conducted at Regional Agriculture Research Station (RARS), Tarahara, Sunsari during 2004-05 and 2005-06 wheat growing seasons to elucidate role of nitrogen in wheat genotypes for management of the disease. Field experiment was laid out on split plot design with three replications. Four doses of nitrogen in six different promising genotypes were tested. Nitrogen levels higher than 50 kg ha -1 significantly reduced disease severity and increased grain yield in all genotypes but there was no significant differences in grain yield in the first year. In the second year, grain yield difference among the genotypes was significant. Area under disease progress curve(AUDPC) was not significant between two doses 100 and 150 kg ha -1 . The wheat genotypes showed different reactions to disease. Genotype BL 2047 had the lowest incidence of disease followed by BL 1887, whereas BL 2217 had the highest incidence of the disease. Genotype BL 2196 produced the highest grain yield (2172 kg ha -1 ) and the lowest grain yield was obtained in Bhrikuti followed by BL 2089. These results suggested that fertilizer should be applied in soil at balanced dose 100:50:50 N:P 2 O 5 :K 2 O kg ha -1 . Growing relatively resistant genotypes with the balance dose of fertilizers can reduce foliar blight severity in wheat. Nepal Agric. Res. J.

A post-harvest study on ripening of banana was carried out at Regional Agriculture Research Station, Khajura during winter season of 2005 to find out the effect of different materials in ripening of banana and study about shelf-life period. Dipping fruits in Kripone 2.56 ml per liter of water (ethephone 1000 ppm) for five minutes was found effective for banana ripening. Those fruits treated with ethephone 1000 ppm started to soften in three days and became ready to consume in five days with shelf-life of eight days. Fruits treated with 'Asuro' ( Adhatoda vesica ) started to become soft in five days where as fruits treated with 'Koiralo' ( Bahunia veriagata ) became soft in four days. By using these indigenous plant materials, we can prolong shelf-life of fruit by 2-3 days more than the Kripone-treated fruits. Use of ripe banana fruit also found effective to hasten ripening the banana with excellent taste. However, the shelf-life was relatively short (8 days). It is difficult to ripen the banana in winter without using any ripening materials. In untreated control, only 33% fruits started to become soft after 7-9 days of storage and were ready to consume in nine days. Rest 66% fruits were remain as such up to 11 days then after fruit started uneven softening ie some portion became soft and other portion remained hard. After 14 days fruits became black without softening and got spoiled. Overall percent weight loss was found 6.0 to 10.7 from initial to end of shelf-life period. Nepal Agric. Res. J.

A survey was carried out to study the productivity of wheat and compare the production between traditional and RCT method of cultivation. Altogether 31 farmers were interviewed with semi-structured questionnaires. Model used to estimate the productivity for both the methods was significant (p < 0.01) which explained 96 and 97 per cent variation due to independent variables under study in wheat production of traditional and RCT method, respectively. Farmers used 160 kg seed/ha in traditional method while in RCT method it was 122 kg/ha. Similarly, they applied 148 and 137 kg nutrients as a total of nitrogen, phosphorus and potash in traditional and RCT method, respectively. Average production of wheat grain in traditional and RCT method was 2456 and 2714 kg/ha giving average gross margin of Rs 16750.00 and Rs 23301.00/ha, respectively. This revealed 10 per cent reduction in total costs and 29 per cent increase in return by RCT method. Nepal Agric. Res. J.

It is grown in different cropping patterns in both Khet and Bari land conditions. A total of 207 accessions of barley landraces collected from various locations of Jumla were studied for agromorphological characteristics in Khumaltar and Jumla. Data on eight qualitative and five quantitative traits in 2-m row plot were recorded to assess diversity among the landraces. Bhuwali, Chawali, Lekali and Pawai were four farmer-named traditional barley varieties under cultivation in Jumla. A range of variability was observed among the accessions of barley landraces. All accessions are six-row covered barley possessing rough awns and whitish-brown grains. These landraces exhibit a range of variation in growth class, spike density and rachilla hair length. Lekali and Pawai are adapted to the high-altitude area of Jumla. Cluster analysis of measured data under on-farm and on-station conditions indicated five distinct clusters. Three principal components explained 84.3% and 60.2% of the total variation from on-station and on-farm, respectively. Nepal Agric. Res. J.

The study was carried out in Nasikasthan Sanga of Kavrepalanchok district of Nepal. Soil samples were collected from fields under improved conventional practice. Samples were taken at 0-15 and 15-30 cm depths and were analyzed for various physico-chemical properties to compare the fertility status of the soils under both the practices. Altogether 68 farmers were interviewed to have information on farming practices and information pertinent to improved soil management practice being adopted by them. Results from soil physico-chemical analysis showed higher fertility of soils under improved practice in terms of more favorable pH level, contents of exchangeable bases, available phosphorus and soil organic matter compared to prevailing conventional soil management practice. Moreover, majority of the farmers believed that soil fertility and physical condition of their upland soils had improved and that the productivity of major upland crops had also increased after the adoption of improved soil management practice. Improved practice could play an important role in the sustainable management of upland soils in the mid hills of Nepal. It is however, desirable to conduct long-term research to further ascertain the effect of the practice on soil fertility of different soil types and land uses. Nepal Agric. Res. J.

The experiments consisted of an open pollinated variety (OPV) 'Deuti' and hybrid 'Gaurab' in different row combinations (50% hybrid + 50% OPV, 75% hybrid + 25% OPV, 75% OPV + 25% hybrid plus their pure stands). The results showed that Gaurab (yellow, flint type) and Deuti (white, semi- flint type, selected from CIMMYT's material ZM 621) did not vary significantly in grain yield and yield components. There was no effect of mixed row culture between the OPV and hybrid for grain yield and yield attributes. A bivariate correlation coefficient between agronomic traits and ear traits indicated that there was a positive relation among these traits. However, a positive and highly significant (r = 0.766**) relationship between ear fill and ear length was observed while a very weak relation (r = 0.096*) between grain weight/ear and ear height was also noticed suggesting taller the ear height lower the grain yield/ear and vice versa. The findings of the study support that plant height and ear height were weakly related with other ear traits; nevertheless, these were highly related to grain weight/per plant. To cope with stalk lodging problem and to attain higher grain yield these varieties are equally potential and recommended to grow under Dukuchhap conditions. Nepal Agric. Res. J.
