    Effect of planting time on growth and flowering of Oriental lily varieties under polyhouse
    (CCSHAU,HiSAR, 2021-07) Rana, Naveen; Malik, Arvind
    The present investigation was conducted at Agri-tourism Centre, CCSHAU, Hisar (Haryana) during 2019-2020 to study the effect of planting time on growth and flowering of Oriental lily varieties under polyhouse. The evaluation of varieties for a particular region is an important process in order to screen the potential cultivars for any specific region. Along with varieties, planting time significantly affect the crop production. Therefore standardization of planting time is very important to get a good growth and excellent quality of cut flowers. The present investigation laid out with five Oriental lily varieties (Casa Blanca, Calexico, St. Andrews, Profundo, Donato) along with three planting time (10th October, 24th October and 8th November) and observation were recorded for various vegetative, flowering and bulb parameters. The data recorded for different parameters were statistically analyzed by OPSTAT-CCSHAU, Hisar (Haryana) software (Sheoran et al., 1998) as per standard procedure for two factor analysis and reported that out of the three planting time, the Oriental lily planted on 10th October performed better results in terms of maximum plant height, number of leaves, leaf length, leaf width, number of flowering bud per plant, flower bud length, flower bud diameter, flower diameter, stem length, stem diameter, number of bulblets per plant, weight of bulb per plant, diameter of bulb and minimum days of bulb sprouting. However, the maximum percentage of sprouting and minimum days to emergence of first flower bud, days to color change of first flower bud, days to opening of first flower bud was recorded in crop planted on 8th November. Among the varieties, St. Andrews performed overall best with respect to highest percentage of bulb sprouting, plant height, leaf length, leaf width, flower bud length, flower bud diameter, flower diameter, stem length, stem diameter, number of bulblets per plant, weight of bulb per plant and diameter of bulb.

    (CCSHAU, Hisar, 2021) Sonu Kumar; Manender Singh
    An experiment was conducted at Guava Demonstration Centre, Bhuna (Fatehabad) and laboratory work was carried out at Dept. of Horticulture and Dept. of MBB&B, CCS Haryana Agricultural University, Hisar during rainy and winter season 2020-21. Fifteen varities having a wide range of variability in growth, fruit, qualitative traits and genetic variation were studied. Results showed that the significant variation was found in case of tree growth habit, leaf and fruit morphological parameters among different varieties. Maximum values for growth characteristics such as foliage density, fruit length, fruit diameter and fruit weight was found in KG Guava. Most of the varieties had spreading type of growth habit, decussate type of phyllotaxy, oblong type leaf shape, dark green colour of leaf, round type of fruit shape, smooth surface of fruit, yellowish green fruit skin colour and creamy-white color of fruit pulp. KG Guava had maximum foliage density and minimum in L-49 in both season. KG Guava had maximum fruit length and minimum in Lalit in both season. Fruit diameter and weight was maximum in KG Guava and minimum in Allahabad Safeda in both rainy and winter season. TSS and TSS-acidity ratio had maximum in Hisar Safeda and minimum in Arka kiran in both season. Hisar Saeda had minimum titratable acidity and maximum in Arka kiran in both season. L-49 had maximum ascorbic acid and minimum in aishwarya in both rainy and winter season. In molecular characterization, Out of 40 primers 5 primers with no amplification among selected guava varieties and all 35 amplified primers were showed polymorphism. Diversity analysis detected a total of 117 alleles ranging from 2 to 7 alleles with an average of 3.34 per locus. The polymorphic information content had an average value of 0.59 across all 15 varieties with the range of 0.08 in mPgCIR251 to 0.84 in mPgCIR255. The primer mPgCIR236 can be used to distinguishe Pant Red from other varieties. Clustering of varieties distinctly separated into two major groups and PCA (2D and 3D) further showing results according to the clustering in Dendrogram. In population structure analysis the all varieties were grouped into two population and all were categorized as pure population. MAJOR ADVISOR

    Performance of ber (Ziziphus mauritiana Lamk.) cultivars under semi- arid conditions of Haryana
    (CCSHAU, Hisar, 2021-09) Hardeep; Mukesh Kumar
    A research study was carried out at the experimental orchard of CCS Haryana Agricultural University, RRS, Bawal (Rewari), Haryana on ber cultivars planted at 7×7 m in RBD. These cultivars have wide range of variability in growth, flowering, fruiting and qualitative traits. Growth parameters such as plant height, trunk girth and plant spread were recorded maximum in Kaithli while, minimum plant height in Chhuhara, plant spread and trunk girth in Narendra Ber Selection 2. The growth habit of all the cultivars was upright, semi-erect or spreading, while the leaf shape was oval, obovate, cordate or ovate. Ber cultivars may also be classified by to the intensity of pubescence on the lower side of the leaf, either smooth, sparsely tomentose or densely tomentose. Maximum leaf fresh and dry weight was recorded in Umran and chlorophyll content in Gola. Superior to half-inferior ovary was observed in all the cultivars. Anthesis occurred in forenoon in some cultivars whereas, in afternoon in others. Dehiscence time was observed from 1 to 3 hours in different culitvars. Thorn shapes was observed curved and alternate curved in all the cultivars. Date of initiation of flowering to end of flowering, flowering duration, time taken from flowering to fruit setting, time taken from fruit setting to fruit maturity varied as 16 August to 31 October, 49-62 days, 16-21 days and 128-151 days, respectively. Mature fruit colour varied as greenish-yellow, yellowish and yellowish-green. The maximum fruit length (4.67 cm) was recorded in Chhuhara and maximum fruit width (3.69 cm) was found in Narendra Ber Selection 1. Fruit weight, pulp weight, specific gravity, stone length, stone weight varied as 16.90-29.43 g, 15.72-26.95 g, 0.98-1.08, 18.16-28.30 mm, 1.07-2.48 g, respectively. The maximum stone length and stone width was recorded in Chhuhara and Narendra Ber Selection 1, respectively, whereas minimum stone length and stone width was rercoded in Narendra Ber Selection 2 and Kaithli, respectively. Pulp/stone ratio, fruit set per cent ranged as 7.54-188.77 and 10.70-19.35, respectively. Fruit firmness in mature fruits was soft, medium and hard. Difference in fruit maturity group was also recorded viz. early, mid and late and yield of different cultivars varied from 24 to 48 kg/plant. Pulp TSS, ascorbic acid, titratable acidity and TSS/acid ratio varied as 15.30 to 20.72ᵒB, 88.7-94.7 mg/100 g pulp, 0.32-0.38% and 42.5-64.8, respectively. Gola and Kaithli were found susceptible in fruit fly infestation and Kaithli was recorded highly susceptible to powdery mildew whereas, Gola, Umran and Chhuhara were found susceptible and others were resistant to powdery mildew. Fruit cracking was also found in Gola and Narendra Ber Selection 1 whereas, frost injury was observed in Chhuhara.

    The study entitled, “Effect of seed priming on germination and seedling growth of bael (Aegle marmelos Corr.)” was conducted during 2020-21 at the Nursery and Laboratory, Horticulture and Microbiology, Regional Research Station Bawal, CCS Haryana Agricultural University with objective to study the effect of seed priming with bio-inoculants and chemicals on germination and seedling growth in bael. There were 15 treatments of seed priming i.e. control, IBA @ 100 ppm for 24 hours, IBA @ 50 ppm for 24 hours, GA3 @ 100 ppm for 24 hours, GA3 @ 50 ppm for 24 hours, NAA @ 100 ppm for 24 hours, NAA @ 50 ppm for 24 hours, KNO3 @ 1 per cent for 24 hours, hot water for 30 minutes, Azotobacter (HT 54) for 30 minutes, Trichoderma viride for 30 minutes, Rhizobium (CK 16) for 30 minutes, PSB (P 36) for 30 minutes, nitric acid for 3 minutes, sulphuric acid for 3 minutes. Among different seed priming treatments, gibberellic acid @ 100 ppm for 24 hours performed best in term of germination (83.3 %), seedling length (12.2 cm), maximum dry weight per seedling (153.2 mg), vigour index I (976) and II (12256). Maximum seed viability (90%), was recorded with GA3 @ 100 ppm for 24 hours) and KNO3 @ 1.0% for 24 hours. However shortest germination time (12.7 days) was recorded with sulphuric acid for 3 minutes in agar medium at 28 ⁰C under laboratory conditions. The performance of seed priming treatments under nursery conditions was recorded best in gibberellic acid soaking @ 100 ppm for 24 hours, it resulted into highest germination (74.07%), seedling height (20.69 cm), inter-nodal length (2.83 cm), number of leaves/plant (20.75), leaf area (39.55 cm2), fresh weight of roots (12.20 g), dry weight of roots (4.88 g), fresh weight of shoots (31.55 g) and dry weight of shoots (9.12 g). Maximum seedling diameter (6.04 mm) and survival per cent (96.47%) were recorded in KNO3 @ 1 per cent for 24 hours and IBA @ 100 ppm for 24 hours respectively. Days to emergence of seedling was recorded minimum (6.00 days) in sulphuric acid for 3 minutes, however, it was recorded highest in control.
