    Study on potato (Solanum tuberosum L.) based crop sequences under rainfed mid-hill condition of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2009-07) Kipgen, Chinpilhing; Uniyal, S.P.
    To evaluate eight potato based crop sequences viz., potato-carrot, potato-turnip, potato- radish, potato-cauliflower, potato-cabbage, potato-broccoli, potato-pea and potato-amaranthus, an investigation was carried out at Vegetable Science Research unit of Hill Campus Ranichauri (G. B. Pant University of Agriculture & Technology), Tehri Garhwal (Uttarakhand) during spring-summer (potato), rainy (carrot, turnip, radish, cauliflower, cabbage) and rainy-autumn (broccoli, pea and amaranthus) season, 2008. The experiment was laid out in Randomized Complete Block Design with three replications. During the study, the yields of individual crops were recorded and based on selling prices, potato equivalent yield (PEY), production efficiency (PE), land use efficiency (LUE) and economics of the sequences were worked out. In order to assess the residual effect of first crop (potato) on subsequent crops of the sequences, soil analysis to different soil parameters (pH, organic matter, available N, P, and K) was also performed. Findings of the investigation revealed that amongst eight sequences, potato-radish proved the best in respect to potato equivalent yield (626.66 qha-1) and net profit (Rs. 1,35,241.70 ha-1). This sequence had recorded an additional net income of Rs. 90,700.70 ha-1 over the conventional sequence, potato-amaranthus. In addition, the other sequences which showed higher profitability in the investigation were potato-cabbage (Rs. 1,07,041.70 ha-1), potato-broccoli (Rs. 1,04,175.00 ha-1), potato-carrot (Rs. 91,375.00 ha-1) and potato-pea (Rs. 85,191.66 ha-1) in decreasing order. Based on the overall performance, it can be concluded that under the prevalent climatic/ cultivation conditions of mid hill rainfed Uttarakhand, potato-radish is the most profitable/suited sequence, hence, recommended for farmer‟s commercial cultivation.

    Studies on interspecific hybridization in brinjal (Solanum melongena L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-06) Karmakar, Pradip; Singh, Y.V.
    The present investigation was conducted during autumn winter season of 2005-06 and 2006-07 at Vegetable Research Centre of Gobind Ballabh Pant University of Agriculture and Technology, Pantnagar, U.S Nagar, Uttarakhand. The experiment was designed to study the crossability relationship among the two commercial cultivars Pant Rituraj, Pant Samrat and wild relatives viz. Solanum gilo, S. aethiopicum and S. khasianum; morphology of the parents and their hybrids and to screen these genotypes against shoot and fruit borer, jassid, phomopsis blight and bacterial wilt. The experiment was laid out in randomized block design with three replication. The findings of the present investigation revealed that cultivated species Solanum melongena was cross-compatible with S. gilo and S. aethiopicum despite the parthenocarpic fruit set in the cross with S. gilo. Morphological variation was observed in the F1 hybrids from their respective parents, while the cross S. melongena cv. Pant Rituraj x S. aethiopicum showed morphology of S. aetiopicum. Among the parents S. khasianum was recorded as resistant to shoot and fruit borer, jassid, phomopsis blight and bacterial wilt; S. gilo showed resistant to shoot and fruit borer, jassid and phomopsis blight while S. aethiopicum was found as promising resistance source against bacterial wilt. Among the F1 hybrids, crosses involving S. gilo as one of the parent showed high level of resistance against shoot and fruit borer, jassid, phomopsis blight but the crosses of S. aethiopicum were ratted as resistant to bacterial wilt. Successful gene transfer from these wild relatives is possible through back cross except from S. khasianum which needs the support of Biotecnological tools.

    Effect of genotypes, environment and their interactions on growth, yield and yield attributes in chilli (Capsicum annuum L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-07) Arora, Indu; Singh, Durvesh Kumar
    An experiment involving twenty four genotypes of chilli and three created environments (E0 – No spray, E1 – Single spray on NAA @ 40 ppm and E2 – Double spray of NAA @ 40 ppm) was carried out during spring summer season of the year 2006 at Vegetable Research Centre, Pantnagar to determine the best genotypes, suitable environment and their interactions for higher production. Out of the three environments, E2 was found better for red ripen fruit yield, number of fruits/plant, 100-seed weight, seed : husk ratio, minimum incidence of disease viz., anthracnose and leaf curl virus whereas, E1 performed better for fresh and dry weight of shoots/plant, fruit length, fruit periphery, weight of fruits/plant, number and weight of seeds/fruit. Significant variations were observed for all the 18 characters. Among genotypes viz., G23 (PC-2062), G24 (PC-2064) and G22 (PC-2057) produced significantly more number of fruits/plant and G20 (PC-7) followed by G21 (PC-56) and G2 (Co-4) performed better for weight of fruits/plant. Genotypes G23 and G21 produced 110.26 and 71.60 per cent higher yield over check variety Pant C-1, respectively. Longest fruits (13.59 cm) were obtained in G20 (PC-7) whereas higher TSS value (16.77°B) were recorded in G2 (Co-4). More number and weight of seeds/fruit were recorded in G22 (PC-2057). Out of all the 72 interactions, G23 E1 was found better for number and weight of fruits/plant whereas, G23E1 (254.42 q/ha), G22E1 and G2E2 produced higher red ripen fruit yield over rest of the interactions. Each genotypes produced variable results under different environments and for different characters. However, the G23 (PC-2062) produced highest fruit yield under single spray of NAA @ 40 ppm followed by PC-2057 whereas, (Co-4) produced higher yield under double spray of NAA (E2).

    Effect of growing medium and seedling age on the performance of tomato (Lycopersicon esculentum Mill.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-06) Khan, Swati; Srivastava, B.K.
    An investigation was carried out during winter season of 2004-05 at Vegetable Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar, district Udham Singh Nagar (Uttaranchal) to study the effect of growing medium and seedling age on the performance of tomato cv. Pant T-3. Treatments comprising of three growing media (M1 – Vermiculite + Perlite + Compost, 1:1:3; M2 – Sand + Soil + FYM, 1:1:2; M3 – Rice bran + Vermicompost, 1:2) and five seedling age (A1 – 15 days, A2 – 20 days, A3 – 25 days, A4 – 30 days, A5 35 days) were tested in all possible combinations. The observations were recorded on growth characters, maturity parameters, yield and yield attributes and quality characters. The results portrayed that growing media and seedling age individually or in combinations, influenced the growth, production and quality of tomato. The overall, evaluation indicated that the growing media containing Vermiculite + Perlite + Compost (1:1:3) followed by Sand + Soil + FYM (1:1:2) proved best. Out of 5 seedling ages, the oldest 35 days gave superior performance than in late November planting. The M1 × A5 combination was found best performer compared to any other media × age interaction. The rice bran + vermicompost media was not found good due to compacting nature of rice bran. Amongst different seedling ages, the 15 days age proved to be too tender to establish in the field.

    Effect of date of planting and spacing on the performance of broccoli (Brassica oleracea var. italica D. C.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-06) Singhal, Preeti; Srivastava, B.K.
    The present investigation was carried out during winter season of 2004-2005 at Vegetable Research Centre of G.B. Pant University of Agriculture & Technology, Pantnagar, District Udham Singh Nagar (Uttaranchal) to study the effect of date of planting and spacing on growth and production of broccoli. Treatments comprising of five dates of planting viz., 1 October, 15 October, 30 October, 14 November and 29 November and three spacings viz,. 45 × 30 cm, 45 × 45 cm and 45 × 60 cm, were tested in Factorial Randomized Block Design with the three replications. The observations were recorded on growth characters, maturity parameters, yield and yield attributes, quality characters and shelf life. The results portrayed that date of planting and spacing individually or in combinations, influenced the growth and production of broccoli. Amongst the dates of planting, 15 October and amongst the spacings the narrowest one i.e., 45 × 30 cm gave the highest yields. Although the average head size was best in the 15 October planting done at 45 × 60 cm spacing but looking at the larger yield difference and reasonably optimum head size, the planting on 15 October at 45 × 30 cm spacing was rated best. The correlation studies showed positive correlation of yield with plant height, stalk length, length of longest leaf and equatorial and polar diameter of the head.

    Studies of heterosis and combining ability in tomato (Lycopersicon esculentum Mill.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-07) Kamal Veer; Bandyopadhyay, B.B.
    The present investigation was conducted during summer season 2003-04 at G.B. Pant University of Agriculture and Technology, Hill Campus, Ranichauri with fifteen diverse genotypes of tomato cultivars and their 56 F1‟s crosses involving 7 lines and 8 testers. The experiment was conducted in the Randomized Block Design with three replications at mid high hill (2000 above msl) of Ranichauri. Suitable agronomic practices were employed for maintaining normal growth and development of plant. Variability genetic parameters, correlation, combining ability and heterosis were examined out for fourteen characters viz. days taken to germination, days taken to first flowering, number of flowers per plant, number of flower nodes, number of fruits per plant, number of leaves per plant, leaf area, average fruit weight, fruit length, fruit diameter, pericarp thickness, TSS, Ascorbic acid, marketable fruit yield. Analysis of variance revealed that significant differences existed for all traits among genotypes. Correlation study suggested that selection in favour of early germination at control condition on seed bed and number of fruits per plant could increase marketable fruit yield in tomato cultivar. Analysis of variance for combining ability showed that considerable variation existed in five characters viz., days taken to germination, number of fruits per plant, leaf area, fruit length and marketable fruit yield. On the basis of gca effect three lines viz. Sioux, AC-1036 and Pant Bahar were identified as good general combiner. One cross combination viz. Sioux x AC 870 was identified from sca effect, which involved one of the best gca lines (Sioux) as a parent in the cross. Heterosis study revealed that Sioux x AC 807 registered significant positive high values for number of fruits per plant and marketable fruit yield. It may be concluded that Sioux x AC 807 was identified as the best suitable high yielding promising genotypes for the mid high hill and rainfed condition of Uttaranchal state.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-06) Bisht, Bhawana; Singh, M.P.
    Eleven varieties of cucumber were evaluated in randomized block design the three replications at Vegetable Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar (Uttranchal). The experiment was conducted in winter season of 2004-2005. The objectives of the investigation were to evaluate promising open pollinated and hybrid varieties of cucumber in a naturally ventilated polyhouse for their earliness, off season and total yield potential and quality attributes to screen out the best and high yielding varieties of cucumber specially suited for protected cultivation. The observation on eighteen characters related to plant growth, flowering, maturity, yield and quality were recorded. The eleven varieties had a wide range of variation for most of the characters under study, similarly, the nature and extent of correlations among various characters varied. The high and positive correlation was obtained between number of primary branches per plant, number of nodes on main shoot and yield. Varieties Poinsette, Rani and Tripti were found to be promising in respect of sensory evaluation. The varieties Poinsette, Phule Shubhangi, US 6125, Rani, Tripti and Pant Kheera-1 were found giving satisfactory performance but the former two were most outstanding for a number of characters under polyhouse condition.
