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
The total of thirteen different avocado (Persea americana Mill.) genotypes were collected for evaluating the fruit characteristics in the laboratory of Agricultural Research Station, Pakhribas during November 2017. The fully matured fruits from the farmer's field at Patle, Dhankuta were collected. The criteria for selecting the genotypes were fruit weight, fruit length, fruit diameter, seed weight, pulp weight, pulp to fruit ratio and the seed weight percentage. The result suggests the potentiality of the genotypes PAKAV002 and PAKAV010 in most of the evaluated characters as compared to the tested genotypes. The genotypes PAKAV008 and PAKAV007 were disliked as they have 32.59% and 28.39% of seed weight to the total fruit weight. The genotypes PAKAV002 and PAKAV010 had the average fruit weight ranging (307.1 g and 346.8 g), maximum of pulp to fruit ratio 62.34% and 56.97%. Similarly, genotypes PAKAV010 (11.425%), PAKAV013 (11.96%) and PAKAV002 (14.47%) had low seed weight to the total fruit weight which is regarded important factor for avocado selection and evaluation. This result shows that the genotypes PAKAV002 and PAKAV010 should be further evaluated for fruit characteristics and the quality.
Background: Onion is an economically important bulbous vegetable crop widely cultivated in India. Onion produced in West Bengal can only partially meet up its domestic need and thus extremely depends upon supply from other Indian States during lean period. Bringing more area under cultivation with improved varieties can boost the production and productivity of onion in West Bengal. The present situation leads to explore the scope of onion cultivation in non-traditional area. The objective of the study was to know the production and storage performance of onion varieties under Coastal Saline Zone of West Bengal, with the greater aim to explore this non-traditional onion growing area in future.Methods: Sixteen short day onion varieties were evaluated in Rabi 2014-15 and 2015-16 in Ramkrishna Ashram KVK, Nimpith following Randomized Block Design with three replications. Eight field parameters, three laboratory parameters and four storage parameters were studied. Result: Enough variation was noticed for different growth, yield, quality and storage attributes among the onion cultivars. The bulb yield, bulb weight, bulb equatorial and polar diameter was ranged from 62.8 to 124.5q/ha, 38.9 to 78.5 g, 32.5 to 47.6 cm and 34.7 to 47.3 cm respectively. The average TSS and pyruvic acid content was noted 12.7 ºBrix and 11.2 µmol/g respectively. After six month of storage in ambient condition, average PLW, rotting, sprouting and total losses was found 33.6%, 24.8%, 1.3% and 59.7% respectively. Among the varieties, Sukhsagar followed by Arka Niketan registered minimum storage losses of 20% and 35.1% at the end of storage period. Onion variety, Sukhsagar, Agrifound Light Red, Bhima Shakti, NHRDF Red-2, Pusa white Flat and NHRDF Red-3 were identified as top performers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
