    (Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-12) Saini, Poonam; Rana, G.S
    The experiment entitled “Studies on nature of fruit drop, yield and quality of Kinnow mandarin” was conducted at the experimental orchard, Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2019-20 and 2020-21 to find out the best concentration of foliar application of growth regulators, nutrients and fungicides in improvement of growth, yield, quality and nutrient status of leaves. There were eighteen treatments, i.e., 2,4-D 10 ppm, 2,4-D 15 ppm, GA3 15 ppm, GA3 20 ppm, Urea 1%, Urea 1.5%, Zinc Sulphate 0.5%, Zinc Sulphate 0.75%, Bavistin 1000 ppm and their combinations with three replications by taking one replication per plant on 9-year-old Kinnow plants. The foliar application of growth regulators, nutrients and fungicides treatments and their combinations had significant effect on fruit drop, growth, yield and quality of Kinnow mandarin. Foliar application of 2,4-D 15 ppm + Urea 1.5% + Zinc Sulphate 0.75% + Bavistin 1000 ppm in Kinnow mandarin recorded lower June fruit drop in the order of 13.65% and 15.77% during 2019-20 and 2020-21, respectively and pre-harvest drop in the order of 25.65% and 34.21% during 2019-20 and 2020-21, respectively as compared to control. The growth parameters i.e., plant spread, trunk diameter, leaf area, fruit retention and leaf chlorophyll content were found maximum with foliar application of 2,4-D 15 ppm + Urea 1.5% + Zinc Sulphate 0.75% + Bavistin 1000 ppm. Plant height, fruit length, fruit breadth and fruit weight were effectively improved by foliar application of GA3 20 ppm + Urea 1.5% + Zinc Sulphate 0.75% + Bavistin 1000 ppm. Foliar application of 2,4-D 15 ppm + Urea 1.5% + Zinc Sulphate 0.75% + Bavistin 1000 ppm was significantly improved number of fruits per tree and yield. Kinnow mandarin fruits sprayed with 2,4-D 15 ppm + Urea 1.5% + Zinc Sulphate 0.75% + Bavistin 1000 ppm resulted in 27.42% and 30.64% higher yield during 2019-20 and 2020-21, respectively as compared to control. Kinnow fruit quality in terms of TSS, acidity, TSS/acid ratio, ascorbic acid, juice content, rag content, peel content and peel thickness were significantly affected by foliar application of 2,4-D 15 ppm + Urea 1.5% + Zinc Sulphate 0.75% + Bavistin 1000 ppm. Number of seeds per fruit and seed weight were not significantly affected by foliar application. Maximum leaf N, Zn, S and Fe were recorded with foliar spray of 2,4-D 15 ppm + Urea 1.5% + Zinc Sulphate 0.75% + Bavistin 1000 ppm, however leaf P and K were not significantly affected by foliar application of plant growth regulators, nutrients and fungicides.

    (CCSHAU,HiSAR, 2020-08) Reddy, Gajjala Chandra; Goyal, R.K
    A field experiment entitled “Effect of biofertilizers in combination with nitrogen, phosphorous and organic manure on growth, yield and quality of strawberry cv. Winter Dawn" was conducted during the year 2017-18 and 2018-19 at hi-tech greenhouse of the Department of Horticulture, CCS Haryana Agricultural University, Hisar. The investigation composed of three experiments viz., (i) effect of biofertilizers in combination with nitrogen on growth, yield and quality of strawberry, (ii) effect of biofertilizers in combination with phosphorous on growth, yield and quality of strawberry and (iii) effect of organic manure in combination with biofertilizers on growth, yield and quality of strawberry. The experiment-I comprised of four levels of nitrogen, i.e., 0, 80, 100 and 120% recommended dose of nitrogen (RDN) and two biofertilizers viz., Azotobacter and Azospirillum. Nitrogen levels and biofertilizers in combination had significant influence on growth parameters such as plant height, spread, number of leaves, crown diameter and fresh and dry weight of plants. The maximum fruit yield parameters and quality traits were recorded with 100% RDN along with biofertilizers. The leaf NPK content was recorded higher in 120 and 100% RDN along with biofertilizers than control treatment. The experiment-II comprised of four levels of phosphorous, i.e., 0, 80, 100 and 120% recommended dose of phosphorous (RDP) along with two biofertilizers, i.e., vesicular- arbuscular mycorrhiza (VAM) and phosphate solubilizing bacteria (PSB). All the possible combinations of phosphorous and biofertilizers were found to have significant influence on vegetative growth, yield and quality parameters of strawberry. The minimum number of days taken to first flowering, maximum fruit weight, size and fruit yield per plant were recorded with 100% RDP along with VAM. TSS and ascorbic acid were noted maximum with combined application of 120% RDP and biofertilizers. The leaf NPK content was significantly higher in 120% RDP along with biofertilizers than the control treatment. The experiment-III comprised of nine treatments, viz., T1: Sand: FYM (3:1), T2: Sand: FYM (2:1), T3: Sand: Vermicompost (3:1), T4: Sand: Vermicompost (2:1), T5: Sand: FYM (3:1) + Azotobacter, T6: Sand: FYM (2:1) + Azotobacter, T7: Sand: Vermicompost (3:1) + Azotobacter, T8: Sand: Vermicompost (3:1) + Azotobacter and T9: Control (Sand). The results indicate that manure in combination with Azotobacter treated plants had better vegetative growth, yield and quality than the control.

    (CCSHAU, Hisar, 2021-08-12) Reetika; Dalal, R.P.S.
    The present investigation was carried out at screen house of the Department of Horticulture, CCS Haryana Agricultural University, Hisar for the two consecutive years during the year 2018-19 and 2019-20 to study the response of citrus rootstocks to salinity. The experiment was laid out in CRD with three replications comprising of nine citrus rootstocks (viz. Rough lemon, Cleopatra mandarin, Pectinifera, Rangpur lime, Alemow, Volkamer lemon, NRCC-3, NRCC-4 and CRH-12) and five salinity levels (viz. control (0.07), 2.5, 4.0, 5.5 and 7.0 dS m-1 NaCl salinity level). The data were recorded on germination parameters of 3-month-old seedlings and growth, chemical and physiological and biochemical parameters of one-year old seedlings. The results of the experiment indicate that the salinity had a significantly negative influence on most of the recorded parameters. The maximum potential of citrus rootstocks of 3-month-old seedlings in respect of the minimum number of days taken for seed germination (14) with Pectinifera and the higher number of seedlings emerged per seed (1.70) in Cleopatra mandarin, a greater number of leaves per plant (27) in Rangpur lime and seed germination (%) was observed maximum (82%) in Volkamer lemon in control (0.07 dS m-1). The minimum reduction in seedling height (39.7%), stem diameter (14.9%), fresh and dry shoot (37.7 and 28%) and fresh and dry root biomass (21 and 26.9%), respectively over control was observed in Rangpur lime, followed by Volkamer lemon and CRH-12. However, minimum reduction (42.8, 41.3 and 18.5%) in plant height, root length and stem diameter were observed in Volkamer lemon and minimum decline in leaf area and number of healthy leaves per plant (61.6 and 48.5%), in fresh (54.6, 52.1 and 49.1%) and dry (48.9, 48.7 and 54.7%) leaf, stem and root biomass, respectively over control was recorded in Rangpur lime, followed by Volkamer lemon and CRH-12. The reduction in growth parameter was less up to 4.0 dS m-1, afterwards there was sharp decline in the above recorded parameters. The maximum accumulation rate of Na+, Cl- and SO42- and the minimum accumulation of Ca2+, Mg2+ and K+ content at 7 dS m-1 when compared with control was recorded in leaves (65.0, 60.7, 36.1, 27.6, 20.3 and 36.4%) and roots (56.5, 56.5, 31.8, 29.0, 20.7 and 29.5%), respectively of Rangpur lime, followed by Volkamer lemon. At 7 dS m-1 salinity level, the highest leaf (12.43, 17.45 and 12.65) and root (12.15, 17.42 and 12.42) proline, glycine betaine and total soluble carbohydrates (μg g-1, μmol g-1 and mg g-1 DW), respectively was recorded in Rangpur lime. Similarly, synthesis of leaf (18.38, 58.27 and 3.46 Units mg-1 protein min-1) and root (18.38, 58.61 and 3.69 Units mg-1 protein min-1) SOD, CAT and APX, respectively enhanced abruptly at 7 dS m-1, however, minimum reduction in chlorophyll stability index (17.2%), leaf and root relative water content (18.7 and 18.9%) and relative stress injury (32.0 and 33.0%), respectively was noticed in Rangpur lime at 7 dS m-1, in addition, the minimum leaf and root MDA (8.46 and 8.12 μmoles g-1 DW) and H2O2 content (907.6 and 876.59 moles g-1 DW), respectively was also recorded in Rangpur lime at 7 dS m-1. It is further concluded that among all rootstocks, Rangpur lime, followed by Volkamer lemon and CRH-12 were found superior with relatively less reduction at 7 dS m-1 over control, however, Cleopatra mandarin, followed by Rough lemon and NRCC-3 exhibited a moderate response with comparatively less reduction, whereas, Pectinifera, followed by Alemow and NRCC-4 were found inferior which showed relatively high reduction at 7 dS m-1 over control in respect of germination, growth, chemical and physiological and biochemical parameters at seedling stage.
