    Seed germination studies in bitter gourd (Momordica charantia L.)
    (CCSHAU, 2010) Narender Kumar; Partap, P.S.
    Seed germination study of bitter gourd varieties Pusa Do Mausmi and Pusa Vishesh under laboratory and field conditions using eight chemicals and three seed soaking durations was carried out in March and August, 2009. Analysis of variance revealed highly significant differences among the treatment effects for different characters in both the varieties for respective seed soaking durations. Test weight of sampled seeds was 17.99g (Pusa Do Mausmi) and 16.96g (Pusa Vishesh). In both sets of experiments varieties differed for all the characters in respective seed soaking durations under laboratory and field conditions where some interactions were also significant. The laboratory seed germination and seedling field emergence for both the sets of experiments and all the three seed soaking durations were found similar but field emergence was lesser than laboratory seed germination in all the treatments investigated. In both the sets of experiment GA3 50ppm followed by KCl (1%) and ZnSO4 (1%) gave significantly higher seed germination then the canal water control treatment in both the varieties. Pusa Vishesh had better germination than Pusa Do Mausmi, however, field emergence was at par in both the varieties. Field emergence (%) and field emergence index were recorded maximum with GA3 50ppm/boron 25ppm and or GA3 50ppm/KCl (1%) and KNO3 (1%) and ZnSO4 (1%). It was lowest with canal water and IBA 75ppm. The other associated parameters of seed quality i.e. seedling length (root/shoot), seedling fresh/dry weight, seed vigour index-I and II were also influenced by the chemical treatments and followed almost the same pattern as of seed germination and seedling field emergence.Seed soaking duration of 12h was better than 24 and 36 h seed soaking.The seed germination, field emergences/index, seedling size, and seed vigour index were reduced with aging of the seeds. The patterns of field emergence, which showed non-to-multi peaks was not consistent for the chemical response, seed soaking duration and also for the crop season. GA3 50ppm, KCl (1%) and KNO3 (1%) with 12h seed soaking appeared most promising for enhancing seed germination/field emergence of bitter gourd varieties.

    Effect of biofertilizers and organic manures on seed yield and quality of fenugreek
    (CCSHAU, 2010) Chaudhary, Rajesh; Tehlan, S.K.
    The field experiment entitled “Effects of biofertilizers and organic manures on seed yield and quality of fenugreek” was conducted at Research Farms, Department of Vegetable Science and laboratories of Department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar during rabi season of 2008-09. The results revealed that application of biofertilizers, organic manures and their combinations significantly influenced the growth, yield and quality parameters of fenugreek except days taken to 50 percent flowering. Seed inoculation with Rhizobium alone or in combination with PSB statistically produced non significant increase in yield over control. However, seed inoculation with Rhizobium along with application of different organic manures was found superior over PSB in term of growth, yield and quality parameters of fenugreek. Similarly, application of organic manures along with seed treatment with biofertilizers (Rhizobium or Rhizobium + PSB) perform better than sole application of organic manures. The treatment combinations viz. Rhizobium + PSB + farmyard manure, Rhizobium + farmyard manure and Rhizobium + PSB + vermicompost produced higher seed yield with better quality which were at par with recommended dose of NPK.

    Effect of nitrogen levels and plant spacing on yield of bottlegourd cultivars
    (CCSHAU, 2011) Mukesh Kumar; Nand Kishore
    The present study entitled “Effect of nitrogen levels and plant spacing on yield of bottle gourd cultivars” was carried out at the Research Farm and Laboratory of Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during the rainy season, 2008. The experiment was laid out in a split plot design with three replications having four levels of nitrogen (50 kg/ha, 62.5 kg/ha, 75 kg /ha, 87.5 kg/ha in main plots), two plant spacing (60 cm and 75 cm) and two cultivars (variety GH-22 and hybrid HBGH-35) in sub plots, thus making a total of sixteen treatment combinations. The plot size per treatment was 15 m2 (2 raised beds of 2.5×3m). The analysis of variance revealed that the differences between nitrogen levels were found highly significant for all the characters except fruit length, fruit diameter and early fruit yield per vine, where the differences were only significant. Differences between plant spacing were highly significant for all the characters except days to first female flower appearance, fruit length, vine length, average fruit weight and fruit yield per vine whereas, the difference in branches per vine was only significant. The differences between cultivars were highly significant for all the characters except fruit length, however, fruit diameter and early fruit yield per vine were only significant. All interactions were not significant for all the characters. First female flower appeared earliest and at lowest node along with first fruit picking with 50 kg nitrogen/ha and 60 cm plant spacing. Maximum fruit length ,fruit diameter, vine length, average fruit weight, fruiting period and number of fruits per vine were recorded with 75 kg nitrogen/ha and 75 cm plant spacing in both the variety and hybrid. Maximum branches per vine, early and fruit yield per vine and dry matter content of fruit were recorded with 87.5 kg nitrogen/ha and 75 cm plant spacing in both the cultivars. The maximum total fruit yield (q/ha) was harvested from 87.5 kg nitrogen/ha with 60 cm plant spacing in both the variety GH-22 and hybrid HBGH-35. The treatment with 87.5 kg nitrogen/ha and 60 cm plant spacing both in hybrid and variety resulted the highest net returns and fetched 21.53% and 19.13% increase in the net returns over recommended packages.

    Assessment of seed quality of okara in summer and rainy season (Ablemoschus esculentus (L) monech )
    (CCSHAU, 2010) Chaudhary, Surjeet; Dhankhar, S.K.
    Seed quality plays an important role in the crop establishment and overall performance of the crop. With an array of possible viability and vigour tests available, appropriate procedure to evaluate seed performance is a very difficult job but a necessity. Keeping this aspect in view present investigation was carried out to evaluate seed quality of three varieties of okra and comparative efficacy of seed viability and vigour test as predictor of field emergence. Seeds of three varieties seeds obtained from summer and rainy season crop were subjected to various viability and vigour tests with four replications and observations were recorded on standard germination, dehydrogenace activity, tetrazolium test, seedling length, speed of germination, test weight, standard germination after accelerated ageing, seed density, seed vigour, seedling dry weight, field emergence and seedling establishment. Results revealed that, among varieties tested, Varsha Uphar was significantly superior to Hisar Naveen and BB-1 in all above quality parameters. The seeds obtained from rainy season were superior from the seeds obtained from summer season. All the parameters were significantly correlated with field emergence (except dry weight of seedling, seed density and dehydrogenace activity). The electrical conductivity was significantly and negatively correlated with field emergence. Standard germination followed by vigour index-II showed highest reliability for prediction of field emergence. Correlation coefficient analysis and regression analysis revealed that viability and vigour parameters like standard germination, seed vigour, tetrazolium test, seedling length and electrical conductivity can be used as reliable predictor of field emergence in okra.

    Effect of seed rate and spacing on seed yield and its quality in fenugreek (Trigonella foenum-graecum L.)
    (CCSHAU, 2011) Vats, Rohit; Rana, M.K.
    The experiment entitled Effect of seed rate and spacing on seed yield and its quality in fenugreek (Trigonella foenum-graecum L.) was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during winter season of 2009-10. The seed material used for the investigation was a released variety Hisar Suvarna (HM-103). The experiment comprising five levels of seed rate (14, 16, 18, 20 and 22 kg/ha) and three levels of row spacing (20, 30 and 40 cm) was laid out in a factorial randomized block design with three replications and plot size 3×2.4 m. Five competitive plants were selected randomly from each experimental treatment to record data on various parameters, which were influenced significantly by various levels of seed rate and plant row spacing. Seed rate showed significant improvement in all the growth, yield and seed quality parameters. The value for the number of branches per plant, days to 50% flowering, days to maturity, number of pods per plant, pod length, number of seeds per pod, number of seeds per plant, test weight, germination percentage and seed vigour index-I was recorded utmost and the electrical conductivity of seed leachates least with a seed rate of 14 kg/ha. However, the value for plant height at 60 and 90 days after sowing and at harvest, average internode length, seed yield per plot and per hectare, biological/Stover yield per plot and per hectare, seed recovery percentage and harvest index was recorded maximum with seed rate 22 kg/ha. Different row spacing had a significant influence on growth, seed yield and its quality parameters. The maximum value for plant height at 60 and 90 days after sowing and at harvest and average internode length was recorded with a row spacing of 20 cm. However, the number of branches per plant, days to 50% flowering, days to maturity, number of pods per plant, pod length, number of seeds per pod, number of seeds per plant, seed yield per plot and per hectare, biological/Stover yield per plot and per hectare, seed recovery percentage, harvest index, test weight, germination percentage and seed vigour index-I were recorded maximum and the electrical conductivity of seed leachates least with a row spacing of 40 cm. Interaction of various levels of seed rate with different row spacing showed remarkable variation for growth, seed yield and its quality parameters except germination percentage and electrical conductivity. Significantly highest value was registered for number of branches per plant, days to 50 per cent flowering, number of pods per plant, pod length, number of seeds per pod, test weight and seed vigour index-1 treatment combination T1S3, i.e., seed rate 14 kg/ha and row spacing 40 cm. The treatment combination T5S3, i.e., seed rate 22 kg/ha and a row spacing of 40 cm, was found to be the best with respect to seed yield per plot and per hectare, biological/Stover yield per plot and per hectare, seed recovery percentage and harvest index.

    Characterization of fenugreek genotypes/cultivars by field and laboratory techniques
    (CCSHAU, 2011) Sengupta, Debabrata; Malik, T.P.
    A study was conducted on “Characterization of fenugreek cultivars/genotypes by field and laboratory techniques” to identify ninety four genotypes under study by plant morphological traits, chemical tests for variety identification and preparation of schimatic diagram on the basis of useful traits having wide variation. Plant morphological characters like plant growth habit, leaf tip, number of pods per plant, yield per plant (g) were found to be the most important diagnostic characters for cultivar identification in fenugreek. Some seed morphological characters like test weight, seed colour, seed luster and seed size were also found helpful to differentiate the fenugreek cultivars. The genotypes were also categorized on the basis of field emergence, day to 50% flowering, plant height, number of primary branches, number of secondary branches, leaf margin pigmentation and leaf serration. However, these traits cannot be reffered as reliable traits for identification of genotypes due to their limited genetic variation. The differential response of fenugreek genotypes to different chemical tests such as phenol test, modified phenol test-A, modified phenol test-B, and potassium hydroxide test was found to be very effective for genotype identification. The schematic diagram on the basis of some important morphological traits has higher resolution in terms of differentiating among genotypes. The schematic diagrams based on seed and chemical test are also very useful for identification of genotypes. Field keys were prepared for each and every genotypes on the basis of some highly heritable characters with wide variability. This field keys has a pivotal role to identify genotypes in the field without any use of coastly chemicals and are fairly comparable with their results. However, for more precise and accurate identification the modern biotechnological tools like DNA finger printing and molecular marker techniques can also be exploited.

    (CCSHAU, 2011) Ishwar Kumar; Baswana, K.S.
    The experiment entitled “Effect of different planting dates and cultivars on growth and yield of potato” was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during winter season of 2009-10. The experiment comprising of five planting dates (30 September, 10 October 20 October, 30 October and 10 November) and four cultivars (Kufri Pukhraj, Kufri Bahar, Kufri Badshah and Kufri Pushkar) was laid out in a split–plot design with three replications keeping net plot size 3.6x3.6 m. Ten competitive plants were selected randomly from each experimental treatment to record data on various parameters, which were influenced significantly by different planting dates and cultivars. The per cent plant emergence at 14, 18 and 22 DAP, plant height, leaf area index, number of tubers >50-75 g grade, total number of tuber/m2, weight of tuber >50-75 g and >75 g grade and total tuber yield , marketable yield were statistically higher with 20 October planting. However, the value for number of stems per hill, number of leaves per stem, leaves weight per hill, weight of tubers >75 g was recorded were maximum with 30 October. The stem weight per hill, number of tubers with up to 25 g and 25-50 g weight of foliage, grades were highest with 10 November and number of tuber >75 g grade with 10 October planting. Different cultivars exhibited significant difference growth and yield parameters except at 26 and 30 DAP. The maximum value for per cent plant emergence, number of tubers up to 25 g, >25-50 g, 50-75 g and >75 g grade, total number of tubers/m2, weight of tubers up to 25 g, and >50-75 g grade, total tuber yield, marketable yield were maximum with cultivar Kufri Pushkar. However, plant height, number of leaves per stem, leaves weight per hill, stem weight per hill, leaf area index and weight of foliage with cv. Kufri Badshah, number of stems per hill, weight of tuber >75 g grade with cv. Kufri Bahar and Harvest index in Kufri Pukhraj. Interaction effect of planting dates and cultivars showed remarkable variation for growth and yield parameters except per cent plant emergence at 26 and 30 DAP. Significantly highest value was registered for per cent plant emergence at 14 DAP, plant height at 45 DAP, number of leaves per stem, leaf area index with planting on 20 October, stem weight per hill, weight of foliage on 10 November with cv. Kufri Badshah. However, plant emergence at 18 and 22 DAP, number of tubers of >50-75 g grade, weight of tubers up to 25 g and >50-75 g grade, total tuber yield, marketable yield on 20 October, number of tubers of >75 g grade and total number of tuber/m2 on 10 October, plant height at 60, 75 and 90 DAP, weight of tubers >25-50 g on 30 October and number of tubers up to 25 g, >25-50 g and >75 g grade on 10 November with cv. Kufri Pushkar. Similarly, Kufri Pukhraj had significantly highest value for number of stems per hill on 20 October and harvest index with 30 September planting. However, Kufri Bahar on 20 October planting showed maximum value for weight of tubers >75 g grade.

    Study on genetic variability in tomato
    (CCSHAU, 2011) Verma, Anand; Partap, P.S.
    The present investigation entitled “Study on genetic variability in tomato” was carried out at Research Farm and Laboratories of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during spring summer season of the year 2010. The analysis of variance exhibited highly significant genotype differences in the material indicating a wide range of variability existing for all the fruit yield and quality characters investigated. The genotypic and phenotypic variances were observed high for fruit yield per plant followed by plant height, average fruit weight, number of fruits per plant and fruit diameter. Similarly, both the coefficients of variation were recorded highest for average fruit weight followed by fruit yield per plant, plant height, number of fruits per truss, number of fruits per plant, fruit diameter and number of flower clusters per plant, while of medium magnitude for rest of the characters and lowest for days to 50% flowering. In general, the higher magnitude of phenotypic variances as well as coefficients of variation then the respective genotypic estimates suggesting good influence of environment in the expression of the traits studied. The estimates of heritability in broad sense ranged from 53.55% for days to 50% flowering to maximum high of 99.33% for plant height followed by fruit diameter. And for all other characters these estimates were above 90%. The estimated values of expected genetic advance for the characters studied followed the same pattern as that of components of variance. These were recorded high for average fruit weight (124.56) followed by fruit yield per plant (101.16), plant height (69.69), number of fruits per truss (68.94), number of fruits per plant (62.99), fruit diameter equatorial and number of flower clusters per plant. While these estimates were in average range for fruit diameter (polar), number of flowers per cluster, number of branches per plant, T.S.S., acidity and ascorbic acid. Hence simple selection appeared effective for improvement of most of these traits. The plant height was observed positively correlated with number of branches per plant, number of flowers per cluster, and number of fruits per truss, and negatively with fruit diameter. The number of branches per plant in turn was found positively associated with number of flowers per cluster, number of fruits per truss, whereas branches per plant exhibited negative association with number of flower clusters per plant, fruit diameter and fruit yield per plant. Flowers cluster per plant exhibited positive correlation with number of fruits per plant, while its relationship besides that with the number of branches per plant, was also found negative with number of flowers per cluster, number of fruits per truss and average fruit weight. Days to 50% flowering were found positively correlated with fruit diameter average fruit weight and fruit yield per plant. The flowers per cluster beside its positive correlation with plant height and branches per plant also expressed positive correlation with number of fruits per truss and number of fruits per plant, while it had negative relationship with flower clusters per plant, fruit diameter and average fruit weight. Number of fruits per truss also had the same trend of relationship as observed for flowers per cluster. The fruit diameter recorded positive correlation with average fruit weight and fruit yield per plant whereas it had negative significant correlation with number of fruits per plant, plant height, branches per plant, flowers per cluster and fruits per truss. The average fruit weight was found positively correlated with fruit yield per plant fruit diameter and days to 50% flowering and its relationship was in negative direction with number of fruits per plant, flower clusters per plant, flowers per cluster and number of fruits per truss. The number of fruits per plant showed positive association with flower clusters per plant, flowers per cluster and fruits per truss and on the other hand negative association with fruit diameter and average fruit weight. The path coefficient analysis depicted that average fruit weight followed by number of fruits per truss and flower clusters per plant contributed maximum directly to yield. Plant height, flowers per cluster and fruits per plant via fruits per truss, days to 50% flowering; fruit size via average fruit weight; flower clusters per plant via branches per plant, and fruits per truss via flowers per cluster contributed indirectly toward yield. Hence, these traits could be considered for improvement in tomato through selection.

    (CCSHAU, 2011) Ahlawat, Sachin; Baswana, K.S.
    The experiment entitled “Effect of irrigation levels through micro-sprinklers on growth and yield of potato” was conducted at Research Area Hi-Tech Greenhouse, Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar during winter (rabi) season of 2009-10. The experiment comprising of five irrigation levels (6 mm, 8 mm, 10 mm, 12 mm of 10 mm CPE and control at 40 mm furrow irrigation) and two cultivars (Kufri Bahar and Kufri Badshah) was laid out in a split–plot design with four replications keeping net plot size 3.6 x 3.6 m. Ten competitive plants were selected randomly from each experimental treatment to record data on various parameters, which were influenced significantly by different irrigation levels and cultivars except in weight of tubers of >50-74g grade where cultivar showed non significant difference. The per cent plant emergence at 15, 20, 25 and 30 DAP, plant height at 45,60,75 and 90 DAP, number of stems per hill, number of leaves per stem, leaves weight per hill, stem weight per hill, leaf area index, weight of foliage, number of tubers >25-50 g, >50-75 g and >75 g grade, total number of tuber/m2, weight of tuber >25-50 g, >50-75 g and >75 g grade and total tuber yield, marketable yield were significantly higher at 12 mm of 10 mm CPE level of irrigation applied through micro-sprinkler irrigation. However, number of tubers up to 25 g grade and weight of tubers up to 25 g grade were maximum at 10 mm of 10 mm CPE level of irrigation. Both the cultivars exhibited significant difference for growth and yield. The maximum value for per cent plant emergence at 15, 20, 25 and 30 DAP, plant height 45, 60, 75 and 90 DAP, number of leaves per stem, leaves weight per hill, number of stems per hill, stem weight per hill, leaf area index and weight of foliage, number of tubers up to 25 g, >25-50 g, 50-75 g and >75 g grade, total number of tubers/m2, weight of tubers up to 25 g, >25-50 g, >50-75 g and >75 g grade, total tuber yield, marketable yield were maximum with cultivar Kufri Badshah. However, harvest index was observed maximum with cultivar Kufri Bahar. These observations showed that Kufri Badshah responded more to micro-sprinkler irrigation. Interaction effect of irrigation levels and cultivars showed remarkable variation for growth and yield parameters except for per cent plant emergence at 30 DAP. Maximum plant emergence was registered at 15, 20, 25 and 30 DAP, plant height at 45, 60, 75 and 90 DAP, number of leaves per stem, leaf area index, stem weight per hill, weight of foliage, number of tubers of >50-75 g grade, number of tubers of >75 g, total number of tuber/m2 grade, weight of tubers >25-50 g grade, >50-75 g grade and >75 g grade at 12 mm of 10 mm CPE level of irrigation with cv. Kufri Badshah. However, number of tubers up to 25 g grade and weight of tubers up to 25 g grade was found maximum at 8 mm of 10 mm CPE irrigation level in Kufri Badshah. Kufri Badshah produced higher total and marketable yield than Kufri Bahar at 12 mm of 0 mm CPE applied through micro-sprinkler irrigation.
