The present investigation was carried out at Horticultural Research Centre, Sardar Vallabhbhai Patel University of Agriculture and Technology, Modipuram, Meerut to study the “Effect of foliar application of nano nitrogen (urea) and chelated zinc on growth, flowering, fruiting, yield and quality parameters of guava (Psidium guajava L.) under western Uttar Pradesh conditions”. The experiment was conducted in a Factorial Randomized Block Design with 16 treatments viz. T1- control, T2- nano N 1.5 ml, T3- nano N 3.0 ml, T4- nano N 4.5 ml, T5- chelated Zn 0.4%, T6- nano N 1.5 ml + chelated Zn 0.4%, T7- nano N 3.0 ml + chelated Zn 0.4%, T8- nano N 4.5 ml + chelated Zn 0.4%, T9- chelated Zn 0.8%, T10- nano N 1.5 ml + chelated Zn 0.8%, T11- nano N 3.0 ml + chelated Zn 0.8%, T12- nano N 4.5 ml + chelated Zn 0.8%, T13- chelated Zn 1.2%, T14- nano N 1.5 ml + chelated Zn 1.2%, T15- nano N 3.0 ml + chelated Zn 1.2%, T16- nano N 4.5 ml + chelated Zn 1.2% and 3 replications during the year 2021-22 and 2022-23. Treatments were applied by foliar spray thrice, one before flowering, second at full bloom and the last spray at the time of fruit set. Different parameters i.e. shoot length (cm), shoot diameter (cm), number of leaves per shoot, number of flowers per shoot, fruit set %, fruit drop %, fruit retention %, fruit length (cm), fruit diameter (cm), fruit weight (g), fruit volume (cc), specific gravity, TSS (˚Brix), acidity (%), TSS : acidity ratio, vitamin C (mg/100 g), pectin (%), total chlorophyll (mg/g FW), total carotenoid (mg/g FW), total sugar (%), reducing sugar (%), non-reducing sugar (%), yield per tree (kg), yield per hectare (q/ha) were recorded during the experimental period. There was significant effect of nano nitrogen (urea) and chelated zinc on growth, flowering, fruiting, yield and quality parameters of guava cv. Lalit. The study revealed that combination of nano nitrogen (urea) @ 4.5 ml/tree and chelated zinc @ 0.8% recorded maximum increase in all the mentioned parameters. Among the doses of nano nitrogen (urea) applied, nano nitrogen (urea) @ 4.5 ml/tree performed the best and nano nitrogen (urea) @ 3.0 ml/tree was also found to be at par. Also, the single doses of chelated zinc applied, chelated zinc @ 0.8% recorded the best findings and chelated zinc @ 1.2% was found to be at par with it. Chelated zinc was found to perform best under quality parameters of guava where internal fruit characteristics was concerned as well as in flowering and fruiting characteristics of guava. It can be concluded foliar spray with combination of nano nitrogen (urea) (4.5 ml/tree) and chelated zinc (0.8%) when applied thrice performs best under western Uttar Pradesh conditions.

    Genetic Fidelity Assessment of Strawberry (Fragaria ananassa Duch.) using Morpho-Physio-Biochemical and Molecular Markers
    (SARDAR VALLABHBHAI PATEL UNIVERSITY OF AGRICULTURE AND TECHNOLOGY, MEERUT- 250110 (U.P.),, 2023-08) VIBHU PANDEY; Dr. Arvind Kumar
    ABSTRACT Name: Vibhu Pandey Id. No.: 4218 Major: Fruit Science Minor: Genetics & Plant breeding Degree: Ph.D. (Hort.) Fruit Science Department: Fruit Science Advisor: Dr. Arvind Kumar Thesis title: “Genetic Fidelity Assessment of Strawberry (Fragaria ananassa Duch.) Using Morpho-Physio-Biochemical and Molecular Markers.” This investigation on the “Genetic Fidelity Assessment of Strawberry (Fragaria ananassa Duch.) Using Morpho-Physio-Biochemical and Molecular Markers.” was carried out in the College of Horticulture. The cultivated strawberry (Fragaria x ananassa Duch.) a hybrid between the 'scarlet' or 'virginia' strawberry (Fragaria virginiana Duch.) and the pistillate South American strawberry (Fragaria chiloensis L. Duch.) is a dicotyledonous, perennial low growing herb grown in most arable regions of the world (Debnath, 2013). Conventionally, strawberry is propagated by runner seedlings but the conventional way of production is not adequate to meet the commercial demand (Ara et al., 2013). The tissue culture technique has been exploited in strawberry to meet the current demand. Tissue cultured plants and conventionally grown plants are tested for establish genetic stability with the help of ISSR markers. Different combinations of PGRs were evaluated for various Callus, shooting and rooting parameters. Callus formation study in MS media supplemented with 2,4-D and BAP was conducted and minimum days taken for callus induction 16.77±0.56 was recorded under 3.0mg/l 2,4-D + 2.0mg/l BAP, callus development percentage was highest 86.67±5.77 which was recorded under the treatment 3.0 mg/l 2,4-D + 2.0 mg/l BAP, weight of callus 1570.73±73.11 mg was recorded under 3.0 mg/l 2,4-D + 2.0 mg/l BAP and Maximum surface area (1504.65±22.93 mm2) of callus was recorded under 3.0 mg/l 2,4-D + 2.0 mg/l BAP. The earliest shoot initiation in 11.07±0.37 days was recorded under SNP 1.0 mg/l, BAP 1.5 mg/l, KN 1.5 mg/l and NAA 0.1 mg/l in MS media and found best among the treatment used in the study. Maximum number of shoots (11.07±0.37) under the combination SNP 1.0 mg/l, BAP 1.5 mg/l, KN 1.5 mg/l and NAA 0.1 mg/l, the highest length of shoot (4.21±0.17 cm) was recorded under the treatment SNP 1.0 mg/l, BAP 0.25 mg/l, KN 0.25 mg/l and NAA 0.1 mg/l, maximum number of leaves per explant (12.24±0.52) was recorded under SNP 1.0 mg/l, BAP 1.5 mg/l, KN 1.5 mg/l and NAA 0.1 mg/l and the maximum shoot regeneration percentage (100.00±0.00%) was recorded under SNP 1.0 mg/l, BAP 1.5 mg/l, KN 1.5 mg/l and NAA 0.1 mg/l. The In vitro regenerated shoots were transferred to the rooting media and earliest root induction (9.21±0.31 days) was observed under SNP 1.0 mg/l, NAA 2.0 mg/l and BAP 0.2 mg/l combination. The root induction percentage (96.67±5.77%) in MS media enriched with SNP 1.0 mg/l, NAA 1.0 mg/l and BAP 0.2 mg/l, maximum number of roots (8.03±0.42) was observed under SNP 1.0 mg/l, NAA 1.0 mg/l and BAP 0.2 mg/l and the highest length of root (3.75±0.46) found in media enriched with combination of NAA 3.0 mg/l and BAP 0.2 mg/l. Biochemical analysis using fruit of the conventionally grown plant showed highest total phenolic content (286.00±33.67 mg GAE/ 100 gm fresh weight), total flavonoid content (484.37±59.10 mg QE/100 gm), total vitamin c content (68.88±8.11 mg / 100 gm fresh weight) and antioxidant activity DPPH (88.43±10.79 % of inhibition) than in in vitro raised plants. A large number of plants can be produced under in vitro aseptic conditions, but there is always a danger of producing Soma clonal variants by tissue culture technology. Thus, the genetic fidelity of micro-propagated plantlets were evaluated using ISSR marker and most of the in vitro and mother plants were highly similar in their genetic constituents.
