    Effect of Bio-vita on tomato production
    (CCSHAU, 2007) Anil Kumar; P. S. Partap
    The present investigation entitled “Effect of Bio-vita on Tomato Production” was carried out at Vegetable Research Farm CCS H.A.U., Hisar during 2004-05 to study the effect of fertilizers, Bio-vita granules and Bio-vita liquid spray levels on tomato CV. Hisar Arun (Sel-7). Data were recorded on flowering, fruit yield and quality characteristics. Earliest flowering and more number of flowers per cluster and fruits per truss were recorded in 75% of RDF+ application of Bio-vita granules @ 20kg/ha + one Bio-vita liquid sprays at early bloom stage of tomato plants. Fruit set was early under treatment 50% of RDF+ without Bio-vita granules + 1 Bio-vita liquid spray at first fruit set stage of tomato plants. Highest fruit set percentage (75.4%) was recorded under the treatment 75% of RDF+ without Bio-vita granules + two Bio-vita liquid sprays (one at pre-bloom and one at early bloom stages of tomato plants). The number of fruits per plant was maximum (36.2) in treatment 75% of RDF + application of Bio-vita granules @ 20kg/ha + three Bio-vita liquid sprays (one at pre-bloom, one at early bloom and one at first fruit set stages). Maximum number and weight of A-grade fruit was observed in treatment 100% RDF+ Bio-vita granules @ 20kg/ha + three Bio-vita liquid sprays (one at pre-bloom, one at early bloom and one at first fruit set stages), while number of B-grade fruit was obtained in 50% RDF+ Bio-vita granules @ 20kg/ha + one Bio-vita liquid spray at first fruit set stage. The maximum number and weight of C-grade fruit was recorded in 100 % RDF + Bio-vita granules @ 20kg/ha + two Bio-vita liquid sprays (one at pre-bloom and one at first fruit set stages). Average fruit weight was significantly influenced by Bio-vita granules and Bio-vita liquid spray levels. It was observed highest (53.5g) in treatment 100% RDF+ Bio-vita granules @ 20kg/ha + two Bio-vita liquid sprays (one at pre-bloom and one at early bloom stages). The application of Bio-vita granules and Bio-vita liquid spray significantly increased the fruit yield. Maximum fruit yield per plant (1.8 kg), per plot (108.6 kg) and per ha (434.4q) was recorded in treatment 75% RDF+ Bio-vita granules @ 20kg + three Bio-vita liquid sprays (one at pre-bloom, one at early bloom and one at first fruit set stages). Total soluble solids and acidity of fruits were not affected significantly by application of different treatments. Ascorbic acid was slightly influenced by application of Bio-vita, seaweed extract. It was found maximum (26.7) in treatment of 50% RDF+ no granules + three Bio-vita liquid sprays (one at pre-bloom, one at early bloom and one at first fruit set stages). The gross returns ranged from Rs.83520 to Rs.173760/ha. The benefit to cost ratio also varied from 0.54 to 2.15. The highest net returns of Rs.118487 was realized from the treatment 75% of RDF + application of Bio-vita granules @ 20kg/ha + three Bio-vita liquid sprays (one at pre-bloom, one at early bloom and one at first fruit set stages). It was followed closely by Rs.116053 from the treatment 50% of RDF+ without Bio-vita granules + 3 Bio-vita liquid sprays (one at pre-bloom, one at early bloom, and one at first fruit set stages). Similarly, there were five other important treatments for higher returns. It was concluded that for increasing tomato production the use of both formulations of Bio-vita as a source of nutrients, for stimulating the utilization of other plant nutrients to fullest extent, and saving on the cost of chemical fertilizers by reducing their requirement for the crop will prove a very helping venture for the farmers. The study needs further confirmation of these results at farmer fields on commercial lines.

    Effect of explants and media combinations on plant regeneration in different genotypes of tomato
    (CCSHAU, 2007) Jammihal, Shivanand N.; Rana, M.K.
    The investigation was carried out on “Effect of explants and media combinations on plant regeneration in different genotypes of tomato” in the Department of Biotechnology and Molecular Biology, Chaudhary Charan Singh Haryana Agricultural University, Hisar during the year 2006 and 2007. Development of protocols for in vitro selection would provide new advances for the production of stress tolerant cultivars in tomato. The seedling of tomato cultivars Hisar Lalima (Sel.18) and Hisar Anmol (H-24) were used as planting material in the present studies. Hypocotyls and cotyledons were used as the source of explants, which were obtained from 25 to 30 days old seedlings grown under aseptic conditions. These explants were cultured on MS medium supplemented with different concentrations of BAP and kinetin in combination with IAA and IBA 0.2 mg/l. Two media, i.e., MS basal fortified with BAP 2.5 mg/l + IAA 0.2 mg/l and kinetin 2.5 mg/l + IAA 0.2 mg/l showed the maximum shoot formation and number of shoots per explant among all 24 different media combinations. The cotyledon explants were found to be more efficient in producing shoot formation. Among 24 treatments, the MS basal containing BAP 2.5 mg/l + IAA 0.2 mg/l for hypocotyls and MS basal supplemented with kinetin 2.5 mg/l + IAA 0.2 mg/l for cotyledons was found the best for days to shoot formation, percent shoot formation and number of shoots per explant. The regenerated shoots produced roots (100%) in both the cultivars Hisar Lalima and Hisar Anmol on MS medium containing IAA 0.2 mg/l, and were successfully hardened and transferred to the screen-house conditions.

    (CCSHAU, 2007) Sanjay Kumar; Dhankhar, S.K.
    A field experiment was conducted to study the effect of boron and zinc on fruit yield of okra [Abelomoschus eleculentus (L.) Moench]" at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar in sandy loam soil under semi-arid conditions during rainy season of 2006-07. Five levels of zinc sulphate (0, 10, 20, 30 and 40 kg/ha) and four levels of borax (0, 5, 10 and 15 kg/ha) along with recommended dose of NPK (100:50:50 kg/ha) were applied in the soil as basal dose before sowing the seeds. The crop was sown in 2.8x2.5 in size plots at a spacing of 60 cm between rows and 30 cm between plants in a randomized block design with 3 replications. The soil application of zinc sulphate as source of zinc and borax as source of boron significantly influenced all the characters under study. Plant height, number of branches per plant, fruit length, fruit diameter, average fruit weight and fruit yield were recorded maximum with treatment combination of zinc sulphate 40 kg/ha and borax 15 kg/ha. The protein content of okra fruits increased with the increased level of zinc sulphate and borax as well, and the maximum content of protein was found with the highest levels of zinc sulphate (40.0 kg/ha) and boron (15.0 kg/ha) application in soil independently and in combination. Combination of zinc sulphate (30 kg/ha) and. borax (15 kg/ha) increased the contents of chlorophyll 'a', chlorophyll ‘b’ and total chlorophyll to its maximum. The fruit yield demonstrated highly significant positive correlation with all the growth and yield contributing attributes.

    Effect of extracts of medicinally important spices on shelf life of tomato
    (CCSHAU, 2008) Sadananda, G.K.; Rana, M.K.
    The present investigation entitled “Effect of extracts of medicinally important spices on shelf life of tomato” was carried out in post harvest laboratory of the Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar during the year 2007. The fruits of tomato hybrid Dev-5031 harvested at green mature and turning stage keeping small pedicel intact were used as experimental materials. The spices extracts used were fenugreek seed extract, ajowain seed extract, turmeric extract, bael leaf extract, ginger extract, basil leaf extract, each at 2 and 5%, control without dipping and control with water dipping. The fruits were dipped for 10 minutes in spices extracts prepared as per treatment and the treated fruits were surface dried and then packed in cardboard boxes lined with newspaper. The tomato fruits of both green mature and turning stage showed minimum value for physiological loss in weight, decay loss, specific gravity and total soluble solids when treated with 5% bael leaf extract, whereas, the maximum value was recorded with control fruits without water dipping. The highest value for fruit firmness, fruit acidity and ascorbic acid content was observed with the treatment 5% bael leaf extract. However, the lowest value was recorded with control fruits without water dipping. Chlorophyll content of tomato fruits decreased with the increase in storage period irrespective of treatments and stages, this was highest in fruits treated with 5% bael leaf extract, but in case of control fruits without water dipping, it was recorded minimum. During the entire storage period, the tomato fruits showed an increasing trend for sugars, carotenoid and lycopene content in both mature green and turning stage. The minimum value for sugars, carotenoid and lycopene content was noticed in fruits treated with 5% bael leaf extract, whereas, the maximum value for sugars was observed in control fruits without water dipping. Higher value for organoleptic test in both mature green and turning stage fruits was noticed with 5% bael leaf treatment, but control fruits without water dipping showed significantly lower value for organoleptic test score. The fruits of both mature green and turning stage treated with 5% bael leaf extract showed high market acceptability for longer period as compared to control and other spice treatments. The tomato fruits of both mature green and turning stage treated with 5% bael leaf extract could be stored with minimum post-harvest quality loss when compared with other treatments.

    (CCSHAU, 2009) Shetty, Anoop A.; Rana, M.K.
    The experiment entitled “Effect of gibberellic acid on growth, yield and seed quality of ajowain (Trachyspermum ammi L.)” was conducted during winter season of 2007-08 at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar. The seed material used for the investigation was a local genotype HAJ-18. In the present experiment, four different gibberellic acid concentrations including control (0, 50, 75 and 100 ppm) were sprayed at four different stages of crop growth (five-leaf, juvenile, flowering and initial seed setting stage). Sixteen treatment combinations laid out in Randomized Block Design (factorial) were replicated thrice making total of 48 plots. Gibberellic acid application showed significant improvement in all the growth, yield and seed quality parameters over control except electrical conductivity. The best results for plant height at harvest, number of branches per plant at harvest, average node length at harvest, days to 50 per cent flowering, dry weight per plant at harvest, number of umbels per plant, number of umbellets per umbel, number of seeds per umbel, number of seeds per umbellet, biological yield, stover yield, seed yield, harvest index, germination percentage, seed vigour index and test weight were recorded with the application of gibberellic acid at 100 ppm concentration. Stages of application of gibberellic acid had a significant influence on growth, yield and quality parameters except electrical conductivity. The maximum values for plant height at harvest, number of branches per plant at harvest, average node length at harvest, days to 50 per cent flowering, dry weight per plant at harvest, number of umbels per plant, number of umbellets per umbel, number of seeds per umbel, number of seeds per umbellet, biological yield, stover yield, seed yield and harvest index were recorded with the application of gibberellic acid at juvenile stage. The maximum values for germination percentage, seed vigour index and test weight were observed with the gibberellic acid application at flowering stage. Interaction of gibberellic acid concentrations with stages of application showed remarkable variation. Interaction of gibberellic acid 100 ppm applied as foliar spray at juvenile stage was found to be the best with respect to all growth, yield and quality parameters except electrical conductivity and harvest index. The best result for harvest index was observed with the interaction of gibberellic acid 75 ppm applied at flowering stage. Electrical conductivity showed a non-significant variation for different concentrations of gibberellic acid, stages of application and also interaction effect.

    (CCSHAU, 2009) Suresh Chand; Batra, V.K.
    The present investigation entitled “Effect of transplanting dates and bio-fertilizer on growth, yield, and quality of tomato cv. Hisar Arun” was conducted at Vegetable Research Farm and Laboratory of CCS Haryana Agriculture University, Hisar to find out the effect of transplanting dates and bio-fertilizer treatments on growth, yield and quality on tomato. The experiment was laid out in Randomized block design with three replications having a plot size of 3x2.70 m. Observations were recorded on vegetative growth, flowering, fruit yield and quality characters. Results indicated that transplanting dates and bio-fertilizer treatments significantly influenced plant height, number of primary branches per plant, days to 50% flowering, days to 1st harvesting, average fruit weight, number of fruits per plant and fruit yield (q/ha). Maximum fruit yield (356.7q) was recorded when the seedlings were xx transplanting on Ist January which was followed by D1 (Ist December).Both the treatments were found statistically at par with each other but significantly superior to transplanting D3 (Ist February). In bio-fertilizer treatment when combined with inorganic fertilizers, B7 (Azotobactor + 100% of recommended N+ recommended P2O5& K2O kg/acre) gave maximum number of fruit per plant and fruit yield (362.2q), which was, closely followed by treatment B4 (Azospirillum + 100% recommended N + recommended P2O5& K2O kg/acre).Both the treatment were found statically at par with the treatment B6 and B3. Among the quality parameters pericarp thickness, total soluble solids, ascorbic acid and fruit acidity were significantly influenced by the transplanting dates and bio-fertilizer treatments.
