“…The present results are in agreement with the reports of various researches who found that growing tomatoes under protected structure during the rainy season reduced the incidence and severity of late blight by creating unfavorable environmental conditions for the infection, growth and development of the disease (Bowen and Kratky, 1982;Palada et al, 2003;Kratky, 2006;Pandey et al, 2006;Srinivasan, 2011;Wani et al, 2011;Kelley et al, 2014). In this regard, some…”

Tomato production is not common during main rainy season, especially in sub-humid climatic conditions like in Bahir Dar. Therefore, an experiment was conducted to study the production potential of tomato using rainshelter and management practices during the 2013 rainy season (June-October) in Bahir Dar. The experimental treatments were laid down in split-plot-design at three replications, where with and without plastic rain-shelter were assigned as main plots and management practices (fungicide and stalking) as sub-plots. The results revealed that tomatoes grown in protected structure were significantly (P<0.01) longer (100.5 cm), had more branches (8.9) and flowered earlier (49.1 days) than those grown under open field condition with the mean values of 50.9 cm, 6.3 and 54 days, respectively. Incidence and severity of late blight and yield of tomatoes were also influenced significantly by growth conditions, management practices and their interactions. Tomatoes grown under rain-shelter structure produced significantly higher total fruit yield (31.3 t ha -1 ) and exhibited low disease incidence (16.7%) and severity indexes (26.7%) on leaves and as well as on fruits with the mean values of 22.4% and 37.9%, respectively. Similarly, sprayed and staked tomatoes produced the highest marketable (35.2 t ha -1 ) and total (41.8 t ha -1 ) fruit yields and exhibited significantly lower late blight incidence and severity. In rainshelter structure, the management practices had similar effects on both disease and yield parameters, where higher yield and lower late blight incidence and severity were generally observed. In open field condition, however, only sprayed and staked tomatoes exhibited lower late blight incidence (23.3%) and severity (24%) on leaves and fruits with the mean values of 39% and 40%, respectively. The highest marketable yield (36.4 t ha -1) obtained from such tomatoes in open field condition was statistically similar with the yield obtained from the corresponding treatment in rain-shelter structure (34.1 t ha -1 ). Generally, the present findings showed that rain-shelter technology reduced incidence of late blight and thus it can be used as alternative technology for the production of tomato during the rainy season in and around Bahir Dar. Moreover, tomato can also be produced in open field using improved management practices such as staking and spraying with appropriate fungicides against late blight and similar diseases. Further research is required to select tomato varieties suitable for rainshelter technology as well as to optimize frequency of pesticide applications as their application may have residual effect on fresh vegetables like tomato.

“…Though tomato is best suited to the Tarai, in low and mid hills, it is becoming increasingly attractive for cash generation in the high hills also (Pandey & Chaudhary 2004). Since, tomato supply from Tarai is constrained by high temperature, low fruit set, low flowering, bacterial wilt etc (Pandey et al 2006), tomato produced from mid June to November months in the hills (400-1800m) fetches higher market price ranging from Rs. 20 to Rs.…”

Plastic house technology and arrival of hybrid varieties have increased the possibility of tomato cultivation in rainy season in high hills. An experiment was conducted to assess the performance of tomato varieties under plastic house for two consecutive years from 2009 to 2010 at National Commercial Agriculture Research Program (NCARP), Pakhribas (1750m), Nepal. The experiment consisted of eight tomato varieties namely, All Rounder, Bishesh, Dalila, Manisha, Srijna, Suraksha, Trishul and US-04 laid out in a randomized complete block design with three replications. The varieties differed significantly for all observed traits. The highest marketable yield was recorded from All Rounder (86.6 t ha-1) followed by Srijana (80.8 t ha-1). Srijana took the shortest period for flowering and harvesting with an average of 37 and 77 days after transplanting respectively. This was also the tallest variety (268.7 cm) with more clusters (36.23) per plant. However, the highest average single fruit weight was recorded from Manisha (61.94g), and the largest fruit size in US-04 with a diameter of 5.78 cm. Based on yield parameter, the varieties All Rounder and Srijana are recommended for commercial cultivation under plastic house conditions.DOI: http://dx.doi.org/10.3126/njst.v12i0.6473 Nepal Journal of Science and Technology 12 (2011) 17-22

“…Pandey et al reported that the highest number of fruits (6.8) was produced by NSITH-162 whereas the lowest number of fruits (5.5) was produced by BL-410 [11]. The highest number of cluster (38.4) was produced by NSITH-162 whereas the lowest number of cluster (14.8) was produced by Avinash-2 among the four varieties Avinash-2, NSITH-162, LTH-61 and BL-410 [12][13][14].…”
