    Mustard green (Brassica juncea L.) is a popular green vegetable grown in the plains and hills of Northern India. It is a rich source of vitamins, minerals, and protein. The present investigation was conducted during Rabi-2021 at the Vegetable Research Block, College of Forestry, Ranichauri, V.C.S.G. Uttarakhand University of Horticulture and Forestry in Mustard Green (var. Local and UHF VR 12-1) with an aim to study the effect ofmicrobial inoculants and inorganic chemicals on growth, yield, yield contributing traits and disease suppression in two varieties of mustard green (Brassica juncea L.) under protected structure and open field conditions in mid hills of Uttarakhand. The experimental data for field studies were laid out in RBD comprising nine treatments and one Control, while laboratory studies were evaluated using a CRD comprising six treatments and Control. In field under open and protected structure conditions, bio-agents (Trichoderma asperellumTh-14, Pseudomonas fluorescens Psf-12, and Bacillus subtilisBs-2), fertilisers (Sulphur and Boron), and the fungicide (Ridomil Gold) were used. The treatments under laboratory conditions were comprised of Bio-agents (Th-14, Psf-12 and Bs-2), fertilizers (Boron and Sulphur) and the fungicide Ridomil Gold through the mode of application of seed treatment only for recording seed quality parameters. To study the effect of colonization of bioagents on nutritional composition of pre-colonized FYM and non- colonized FYM, three bioagents namely Th-14, Psf-12 and Bs-2 were used and non-colonized FYM served as Control for the comparative studies. The treatment T4 (Seed bio-priming with Th-14 + FYM pre-colonized by Th-14+ one drenching at 45 days of transplanting with Th-14) recorded the highest plant height, chlorophyll content, leaf length, leaf width, number of leaves per plant, leaf yield, plant height, number of branches per plant, number of siliquae per plant, length of siliqua, and seed yield followed by T7, whereas Control, in both open and protected conditions, recorded the lowest.Similarly, T4 (Seed bio-priming with Th-14 + FYM pre-colonized by Th-14+ one drenching at 45 days of transplanting with Th-14) also showed minimum disease incidence (Damping off and Alternaria blight) and disease severity (Alternaria blight) followed by T9 whereas Control revealed maximum disease incidence and severity. In laboratory studies, maximum first count per cent, germination per cent, root, shoot and seedling length, seedling fresh and dry weight, vigour index-I and II were found when seeds were treated with T1 (Seed treatment with Trichoderma asperellum Th-14) when compared to other treatments and Control.In the study related to the nutritional composition of pre-colonized FYM and non-colonized FYM, organic carbon, nitrogen, phosphorous, and potassium content were found to be maximum in Trichoderma asperellumTh-14 pre-colonized FYM and minimum was reported in Control. From the present investigation, it may be concluded that, seed treatment with Trichoderma asperellumTh-14 improved all the seed quality parameters in both the studied varieties of Vegetable Rai. The application of seed bio-priming with Trichoderma asperellumTh-14 + FYM pre-colonized by Th-14 was found to be the most effective and promising for enhancing growth, yield and resistance to damping off and Alternaria blight disease in Brassica juncea under both open and protected structure conditions. The nutritional composition was found to be enhanced in FYM pre-colonized with Trichoderma asperellum Th-14. When compared to open and protected conditions, the protected condition offered the best results as all the studied growth, physiological and yield parameters performed well under protected conditions. Disease incidence and severity of Alternaria blight were high in open field environments, whereas disease-free circumstances existed in protected settings. The variety UHF VR 12-1 was found best with respect to all the studied traits when compared with the local variety under present materials and environmental conditions.

    Response of wheat (Triticum aestivum L.) to foliar application of nano-nitrogen.
    (College of Forestry, Ranichauri Campus, V.C.S.G. Uttarakhand University of Horticulture and Forestry, 2022) Uniyal, Suchita; Kumar, Ajay (Dr.)
    The world’s one-third population is dependent on wheat Triticum aestivum L. for their food requirement. It contains higher protein than the other major grains. The indiscriminate use of fertilizers (Urea, D.A.P and M.O.P) are resulting in nutritional imbalances in soil, environmental hazards and a rise in production costs. Conventional nitrogenous fertilizers, can be lost or rendered inaccessible to plants by processes such as leaching, NH3 volatilization, denitrification, immobilization, and fixing in the soil solids as NH4-N which results 30-40 % fertilizer use efficiency. Therefore, to increase the nitrogenous fertilizer use efficiency and reduction of their ill effects there is need to use nano-nitrogen. Therefore, to access the response of wheat to foliar application of nano-nitrogen, the field and lab experiments were planned. The treatments comprised of T1- RDN (60:30:20 kg/ha), T2- 75 % RDN, T3- 50 % RDN, T4- RDN + nN (T), T5- RDN + nN (F), T6- RDN + nN (T+F), T7- 75 % RDN + nN (T), T8- 75 % RDN + nN (F), T9- 75 % RDN + nN (T+F), T10- 50 % RDN + nN (T), T11- 50 % RDN + nN (F), T12- 50 % RDN + nN (T+F), T13- nN (T), T14- nN (F), T15- nN (T+F), were evaluated in randomized complete block design with two replications at REC, Gaja during the rabi season 2020-2021. The seed quality parameters of harvested wheat seed were accessed in lab in complete randomized design with four replications. The significantly higher plant growth parameters and seed yield were recorded in 75 % RDN + nN (T) (2ml/litre water) than the RDN (60 kg). The treatment 75 % RDN + nN (T) and 75 % RDN + nN (T+F) gave 26 % and 11 % more grain yield, respectively as compared to the RDN. The maximum B:C ratio (2.9: 1) was also registered with 75 % RDN + nN (T). The seed quality attributes like germination percentage, seedling fresh weight, seedling dry weight, vigour index I and II, speed of germination, germination percentage in cold test and water sensitivity test were recorded significantly higher in 75 % RDN + nN (T+F) than the RDN. Based on the present experiment, 75 % of RDN (60 kg) + nN (T) @ 2ml/litre water might be beneficial for higher seed yield and quality of wheat under rainfed condition of mid hills of Uttarakhand.

    Potential of fluorescent pseudomonads isolates on growth, yield, yield contributing traits and providing resistance against major endemic diseases in finger millet (Eleusine coracana L.)
    (College of Forestry, Ranichauri Campus, V.C.S.G. Uttarakhand University of Horticulture and Forestry, 2021-03) PETWAL, HIMANI; Rawat, Laxmi (Dr.)
    Finger millet is a seeded annual cereal which belongs to the grass family, Poaceae. It is gluten-free, high incalcium and iron, having excellent malting qualities and can be stored for up to two years. Like many othercrops,fingermilletissubjectedtovariousproductionconstraintsincludinglackofimprovedvarieties,traditional production practices and diseases. Several bacterial, fungal and viral diseases have been reported asmajor production constraints of which blast, cercospora leaf spot (CLS) and brown leaf spot (BLS) are mostdreaded in mid hills of Uttarakhand. To avoid losses, farmers resort to indiscriminate applications of plantprotection chemicals that also harm the ecosystem and lead to resistance build-up in the phytopathogens.Therefore, alternative eco-friendly strategies need to be evolved and put in place. Little is known about theimpact of introduced indigenous beneficial rhizobacteria on the rhizosphere microbiota, growth promotion anddiseasesuppressioninfingermillet.Therefore,thepresentstudywasundertakentoidentifycompetentrhizobacteria having promising plant growth promotion efficiency and biocontrol activity against major endemicdiseases in Ragi. A total of 50 rhizospheric pseudomonads were isolated from different minor millets, andthereafter characterized biochemically. Many isolated fluorescent pseudomonds were identified as good HCNproducer, siderophore producer and P-solubilizer. Further, all the isolates were evaluated for their antagonisticactivity against the three major pathogens using dual culture assay viz., Pyricularia grisea, Cercosporaeleusinisand Drechsleranodulosum, of which 12 isolates viz., Rani Psf-7, 13, 19, 24, 27, 31, 35, 39, 45, 47, 48 and 50showed maximum per cent inhibition against all the three tested pathogens. Among all the isolates, Rani Psf-13exhibited maximum per cent inhibition with 85.87 % towards Pyriculariagrisea, 86.00 % inhibition towardsCercosporaeleusinisand86.12%inhibitiontowardsDrechsleranodulosumfollowedbyRaniPsf-50with 85.62 %, 85.75 % & 85.62 % inhibition towards Pyricularia grisea, Cercosporaeleusinisand Drechsleranodulosum,respectively. Out of fifty isolates, twelve putative fluorescent pseudomonads when applied through seed treatment performedbest with respect to planting value parameters in finger millet when compared to untreated control by blotterpaper method. However, among all the tested isolates, Rani Psf-13 performed best with respect to seed qualityattributes viz., first count (46.33 %), standard germination per cent (100 %), root length (9.87 cm), shoot length(6.87cm),seedlinglength(16.73cm),seedlingfreshweight(0.250g),seedlingdryweight(0.103g),andvigourindex-I (1673.33) andII (10.33). The present study also investigated the effect of all the putative twelve isolates under field conditions forassessmentofmorpho-physiologicaltraitsanddiseasemanagementinfingermillet(var.PRM-2).Evaluationunderfield conditions revealed that different pseudomonads isolates suppressed the target diseases significantly whenappliedasseedtreatmentalongwithtwofoliarsprays.Alltheselectedisolatesexhibitedasignificantenhancement in plant growth and yield parameters. Maximum number of effective tillers plant-1 (3.89), plantheight (91.80 cm), ear length (8.86 cm), 1000 grain weight (3.42 g), and grain yield plot-1 (0.551 kg) wasrecorded in treatment T2 (Rani Psf-13) while, minimum was observedin T13 (untreated control). Thus, it isconcluded that seed treatment (10 g/kg seeds) and two foliar sprays (10 g/litre water) with Rani Psf- 13 was found bestin improving growth, yield, yield contributing traits and providing resistance against major endemic diseases infinger millet under present experimental materials and conditions.

    (College of Forestry, Ranichauri Campus, V.C.S.G. Uttarakhand University of Horticulture and Forestry, 2021) ANAMIKA; Rawat, Deepa (Dr.)
    One soil less petri plate bioassay and a green house experiment in germination trays was carried out at College of Forestry, Ranichauri, Tehri Garhwal, Uttarakhand during 2019-2020 to investigate the effect of NaCl seed priming on germination and seedling growth of legumes under soil application of pine needle biochar. The study consisted of twelve treatments in viz; control (T1), 4% NaCl priming (T2), 6% NaCl priming (T3), 10 t/ha biochar (T4), 30t/ha biochar (T5), 50t/ha biochar (T6), 4% NaCl priming + 10t/ha biochar (T7), 4% NaCl priming + 30t/ha biochar (T8), 4% NaCl priming + 50t/ha biochar (T9), 6% NaCl priming +10t/ha (T10), 6% NaCl priming + 30t/ha biochar (T11) and 6% NaCl priming + 50t/ha biochar (T12). Complete Randomized Design was applied for analysis of data under lab and green house experiments. In the preliminary investigation under soil less petri plate bioassay, the growth parameters i.e germination %, first count, speed of germination, relative growth index and mean daily germination in ricebean, and faba bean whereas, highest speed of germination was recorded in lentil which showed significantly higher values with the treatment containing 4% NaCl priming (T2). The combination of pine needle biochar @ 10 t/ha with 4 % NaCl (T7) seed priming under soil less bioassay in petri plates showed significantly higher root length, shoot length, seedling length, fresh weight of seedlings, dry weight of seedlings, vigour index I and vigour index II in ricebean and lentil. In faba bean the NaCl seed priming with 6 % solution along with 10 t/ha pine needle biochar (T10) recorded significantly higher root length, shoot length, seedling length, fresh weight of seedlings, dry weight of seedlings, vigour index I and vigour index II in faba bean. In green house experiment under germination trays, 4% NaCl priming with 10 t/ha biochar (T7) recorded significantly higher germination percentage, root length, shoot length, seedling length, fresh and dry weight, vigour index I, vigour index II, NPK concentration and their uptake at 20 DAS in ricebean. Similar results were obtained for lentil with the exception of germination percentage which did not show significant variation among the values for different treatments. In case of faba bean, 4% NaCl priming with 50 t/ha pine needle biochar (T9) recorded higher root length, seedling length, fresh and dry weight, vigour index I & II and NPK content and their uptake at 20 DAS whereas, highest germination percentage was recorded with application of 4% NaCl priming under 30 t/ha pine needle biochar (T8). The results obtained in the present study concluded that the NaCl seed priming at lower concentration i.e 4 % solution improved the germination and seedling development of legumes viz. ricebean and lentil when used with application of 10 t/ha pine needle biochar whereas 4 % NaCl seed priming with 50 t/ha biochar has improved most of the seedling growth parameters in faba bean. However; for the conformity of these results and standardization of priming doses with pine needle biochar, long term field experiments are required to be conducted.

    (College of Forestry, Ranichauri Campus, V.C.S.G. Uttarakhand University of Horticulture and Forestry, 2021) SINGH, SUDEEP; Rawat, Deepa (Dr.)
    The present investigation was conducted during Rabi season 2019-20 in glass house and laboratory of department of Seed Science and Technology, College of Forestry, Ranichauri, V. C. S. G. Uttarakhand University of Horticulture and Forestry, Bharsar, Pauri Garhwal, Uttarakhand. The experiments were conducted with twelve treatments on different varieties of two crops i.e three varieties of wheat (VL-829, HD-2967, HD-3086) and barley (PRB-502, PRB-701, PRB-501) each. Four doses of corn cob biochar (control, 10 t/ha, 20 t/ha and 30 t/ha) were administered under the study and three experiments (viz. i. Soil less petri-dish bioassay, ii. Experiment in germination trays iii. Pot experiment) were laid in two factorial Completely Randomized Design. Under the first experiment on soil less petridish bioassay a preliminary investigation was performed which showed that for wheat, germination % and speed of germination were higher for HD-3086 (V3). The varieties V1 and V2 showed higher Vigour index I and II, respectively. Among the varieties of barley, PRB- 501 (V3) was recorded with significantly higher germination %, root length, seedling fresh weight and dry weight and vigour index II. The biochar doses significantly decreased the germination and growth parameters in wheat and barley varieties under soil less petri-dish bioassay. In the second experiment for estimation of germination and seedling growth in soil and biochar mixture with different doses of corn cob biochar in germination trays, the germination %, root length, shoot length, seedling length, fresh weight and dry weight of seedlings, seedling vigour index I and II were found to be significantly increased under B1 (10 t/ha biochar) in both the crops. In terms of varieties, wheat variety V3 showed significantly higher germination %, root shoot ratio and vigour index II while highest root length, shoot length, seedling length and vigour index I was recorded for V1 (VL-829). The seedling fresh weight and dry weight was recorded to be significantly higher for V2 (HD 2967). In case of barley varieties, variety V3 showed significantly higher shoot length, seedling fresh weight, dry weight and vigour index II and vigour index I was noted higher for variety V2 (PRB-701). Under the pot experiment, the wheat variety V2 exhibited highest number of leaves at 90 DAS and at plant harvest, highest uptake of N and P in grain along with highest grain yield. The barley variety V2 was recorded with maximum grain and straw yield along with maximum P uptake in grain and straw. Among the doses of biochar, B1 (10 t/ha biochar) showed comparatively more increase in germination, yield and other parameters than control and higher doses of biochar. The results of the present investigation showed that in the wheat and barley crops, wheat variety HD-3086 and barley variety PRB-501, responded more affirmatively to corn cob biochar in terms of seed germination and seedling growth whereas highest grain yields were recorded for wheat variety HD-2967 and barley variety PRB 701. The corn cob biochar at lower rate i.e 10 t/ha was found to be more effective than higher doses.

    EVALUATION OF SEED VIGOUR TESTS TO PREDICT THE FIELD EMERGENCE POTENTIAL OF FINGER MILLET AND BARNYARD MILLET VARIETIES
    (College of Forestry, Ranichauri Campus, V.C.S.G. Uttarakhand University of Horticulture and Forestry, 2021-01) RAWAT, ABHA; Kumar, Ajay (Dr.)
    Vigour is one of the important characteristic of seed quality. No vigour test is likely to perform best to all crops. The vigour test should be crop specific and very little information is available about the vigour test for finger millet and barnyard millet. The experiments on vigour tests viz., physical, physiological and biochemical tests were conducted in CRD (Complete Randomized Design) with four replication. There was six treatments consist of six varieties, three each of finger millet (PRM-1, PRM-2 and VL-352) and barnyard millet (PRB-903, VL-207 and PRJ-1). All vigour test experiments procedure was followed as per standard guidelines. The field experiment consist of six treatment (T1 PRM-1, T2 PRM-2, T3 VL-352, T4 PRB-903, T5 VL-207 and T6 PRJ-1) was laid out in the RBD (Randomized Block Design) with four replication. The field emergence, seedling establishment and field emergence index was recorded during the field experiment. The data were analyzed statistically to find out the result of the study in laboratory and field conditions. Finger millet variety PRM-2 and PRB-903 of barnyard millet were recorded significantly higher test weight, seed density, first count, final count, standard germination, seedling shoot length, seedling root length, total seedling length, seedling fresh weight, seedling dry weight, seedling vigour index I, seedling vigour index II, speed of germination, relative growth index, paper piercing test, cool germination test, mean daily germination, radical emergence, accelerated ageing test and electrical conductivity than VL-352 of finger millet and VL-207 of barnyard millet. Similarly, in field study PRM-2 and PRB-903 were recorded significantly higher field emergence, seedling establishment and field emergence index. The field emergence was correlated with different vigour test viz. test weight, final count, standard germination, seedling vigour index I and relative growth index in both finger millet and barnyard millet. The highly positive and significant correlation was found in test weight(r= 0.859** in finger millet and r= 0.807** in barnyard millet) and seedling vigour index I (r= 0.990** in finger millet and r= 0.999** in barnyard millet) with field emergence. On the basis of the study it could be concluded that PRM-2 of finger millet and PRB-903 of barnyard millet were more vigorous. The seedling vigour index I and test weight could be considered to predicting the field emergence of finger millet and barnyard millet.

    (College of Forestry, Ranichauri Campus , V.C.S.G. Uttarakhand University of Horticulture and Forestry, 2017-07) Uniyal, Ankita; Khanduri, V. P. (Dr.); bhim jyoti (Dr.), (Co-advisor)
    The present investigation was conducted during Kharif, 2015 at Research Block, Department of Crop Improvement, V. C. S. G. Uttarakhand University of Horticulture and Forestry, College of Forestry, Ranichauri Campus, Tehri Garhwal, Uttarakhand. The 34 diverse genotypes of rice bean including four checks varieties viz., PRR-1, PRR-2, and RBL-1and RBL-6 were evaluated in Augmented Design with four replications. Observation were recorded for field and seed quality parameters. Field parameters were recorded for days to 50 per cent flowering, days to maturity, plant height (cm), pod length (cm), number of pods per plant, number of primary branches, number of seeds per pod, 100 seed weight (g) , seed yield per plant (g) and number of clusters per plant. The seed quality parameters were recorded for speed of germination (%), standard germination (%), root length (cm), shoot length (cm), seedling fresh weight (g), seedling dry weight (g), moisture content (%) and accelerated ageing test. The data was analyzed for estimation of mean, range, coefficients of variation, heritability and genetic advance, correlation coefficients. The genotypes RBL-1, PRR-1, IC-341986 and PRR-2 exhibiting high mean performance for seed yield and their component. High magnitudes of phenotypic and genotypic coefficient of variation were noticed for plant height, 100 seed weight and number of pods per plant. High estimates of heritability coupled with high genetic advance as per cent of mean were observed for clusters per plant, 100 seed weight, plant height and pods per plant. Seed per pod exhibited very strong positive association with pod length, pods per plant, clusters per plant and plant height at phenotypic and genotypic level. From this study it is suggested that genotypes viz RBL-1, PRR-1, IC-341986 and PRR-2 can be utilized for improving the yield of rice bean genotypes.
