    Impact of plant growth regulators on growth, yield and quality of guava (Psidium guajava L.) cv. Hisar Safeda in winter season
    (CCS HAU, Hisar, 2022-07-15) Pravesh Kumar; Manender Singh
    The present investigation was carried out to study the “Impact of plant growth regulators on growth, yield and quality of guava (Psidium guajava L.) cv. Hisar Safeda in winter season” in the Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2021-22. The experiment comprised of ten different foliar treatments with three replications and were laid out in randomized block design (RBD) to assessed the effect of plant growth regulators on growth, yield and quality of guava. The results revealed that all the plant growth regulator treatments at different concentrations had significantly influenced yield, fruit development and quality parameters over absolute control. Among different treatments, for yield parameters, T6 (NAA at 100 ppm) performed better in terms of fruit set (56.73 %) whereas, T9 (GA3 at 100 ppm) observed better for fruit retention (59.85 %), fruit drop (40.17 %), no. of fruits per plant (364.52) and yield (65.49 kg/plant). Furthermore, for fruit development parameters, T9 (GA3 at 100 ppm) was found better in terms of diameter of fruit (7.23 cm), length of fruit (7.20 cm), average fruit weight (179.67 cm), average seed weight (3.21 g), fruit volume (179.22 cc). Moreover, for quality parameters, T6 (NAA at 100 ppm) performed better in terms of TSS (14.53 oB), acidity (0.31 %), TSS/Acid ratio (46.87) and sugar content i.e. total sugar (7.84 %), reducing sugar (4.63 %) and non-reducing sugar (3.21 %) while, T9 (GA3 at 100 ppm ) recorded better for pectin content (0.98 %), firmness of fruit (6.08 kg/inch) and ascorbic acid content (196.59 mg/100g pulp). However, parameters i.e. specific gravity and days to maturity were observed non-significant means all the treatments at different concentration were not significantly influenced these traits.

    Effect of floral preservatives and growth regulators on post harvest quality and vase life of tuberose
    (CCSHAU Hisar, 2022-08) Nasima; Sonu Kumari
    The present investigation entitled "Effect of floral preservatives and growth regulators on post harvest quality and vase life of tuberose” was carried out at laboratory of Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year of 2022. Fifteen treatment combinations consisting of seven chemicals viz., sucrose (2% and 4%), citric acid (250 mg/l and 350 mg/l), silver nitrate (25 mg/l and 50 mg/l), aluminium sulfate (150 mg/l and 300 mg/l), gibberellic acid (100 mg/l and 150 mg/l), benzyal adenine (100 mg/l and 150 mg/l) and salicylic acid (100 mg/l and 150 mg/l) along with control (distilled water) were used in Completely Randomized Design with three replications. The vase solution of 4% sucrose + 150 mg/l salicylic acid (SA) was found promising in terms of number of opened florets per spike, percentage of opened florets per spike, freshness index, spike weight at wilting of 3rd floret, floret diameter, vase life and water uptake. This treatment was also found significant in reducing number of unopened florets per spike, water loss/water uptake ratio, physiological loss in weight and proximal end browning. However, the minimum days to opening of 3rd floret and number of florets open at a time was recorded in 4% sucrose +300 mg/l aluminium sulfate treatment.

    Influence of bio- inoculents in combination with organic manures on fresh on seed germination and seedling growth of fresh and aged seeds of guava
    (Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-09) Reenu devi; Reenu devi; Sharma, Jeet Ram; Sharma, Jeet Ram
    The present investigation was carried out to study the effect of pre-sowing treatments on seed germination and seedling growth of guava (Psidium guajava L.) in the Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2021-22. The experiments comprised of 15 different pre-sowing treatments viz, T1 (control), T2 (Sand + FYM), T3 (Sand + FYM + PSB), T4 (Sand + FYM + Azotobacter), T5 (Sand + FYM + VAM), T6 (Sand + FYM + PSB+ Azotobacter), T7 (Sand + FYM + PSB + VAM), T8 (Sand + Vermicompost), T9 (Sand + Vermicompost), T10 (Sand + Vermicompost + PSB), T11 (Sand + Vermicompost + Azotobacter), T12 (Sand + Vermicompost + VAM), T13 (Sand + Vermicompost + PSB + Azotobacter), T14 (Sand + Vermicompost + PSB + VAM), T15 (Sand + FYM + PSB + Azotobacter + VAM) with three replications in fresh and aged seeds of guava laid out in open field condition. Pre-sowing treatments significantly influenced seed germination and seedling growth of guava. Among different pre-sowing treatments, T15 (Sand + FYM + PSB + Azotobacter + VAM) performed best in terms of germination percentage, minimum no. of days taken for germination, maximum vigour indexes (vigour index- I and vigour index- II), maximum height of seedlings, Girth of seedling, maximum no. of leaves per seedling, maximum leaf area, maximum chlorophyll content, maximum fresh and dry weight of leaves, maximum fresh and dry weight of shoots, maximum number of roots, maximum root length, maximum fresh and dry weight of roots, maximum nitrogen, phosphorus and potassium content in leaf and soil in case of fresh and aged seeds of guava.

    Effect of pruning on fruit production of ber (Ziziphus mauritiana) cv. Umran
    (Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-07) Vinay; Murari Lal
    The present investigation entitled, "Effect of pruning on fruit production of the ber (Ziziphus mauritiana) cv. Umran" was conducted in the orchard of village Chang district Bhiwani of Haryana during the year 2021-2022. The experiment was planned using randomized block design (RBD). Four distinct degrees of pruning intensities (T1= 0%, T2= 25%, T3= 50%, and T4= 75%) were applied on the ber trees. Maximum plant shoot length, the diameter of the shoot and leaf area were observed in (T4) severe pruning, followed by (T3) moderate pruning. Plant spreading increases with control (T1) and decreases with (T4) severe pruning. As pruning severity increased, the fruit yield decreased compared to (T1) control (218.17 kg/plant). Trees pruned up to 50% pruning intensity (T3) had greatest fruit weight (34.88 g) and fruit size in terms of pulp weight (33.08 g), fruit length (44.03 mm) and fruit diameter (37.26 mm). Severe pruning reduced stone weight (1.63 g) over control. The pulp stone ratio was highest in (T3) moderate pruning (18.50). T.S.S., ascorbic acid, and T.S.S. acidity ratio was maximum under severe pruning (75%) and decreased as pruning intensity increased. Acidity and specific gravity have no major impact on pruning.
