    Isolation, screening and evaluation of arbuscular mycorrhiza for the management of tomato wilt caused by Fusarium oxysporum f. sp. lycopersici
    (Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-11) Sarita; Narender Singh
    Investigations were carried out on isolation and screening of arbuscular mycorrhiza on tomato wilt cause by Fusarium oxysporum f.sp.lycopersici.Samples for the investigation were collected from the tomato fields of COA, Bawal and its adjoining area and the vegetable farm of Hisar (also adjoining area) for collection of rhizosphere soils of tomato for isolation of mycorrhizal spores. Among all these samples total of 20 isolates (HM-1 to BM-10) were selected for further study. Mycorrhizal fungi were maintained on wheat (Triticum aestivum) and pearl millet (Pennisetum typhoides). In soil, the sporocarp population was highest in Glomus fasciculatum (8774), while mycorrhizal colonization was more in Glomus mosseae (96.1 %) among all the treatments. Effect of the mycorrhizal species (Glomus fasciculatum, Glomus mosseae, Glomus intraradices and Glomus hoi) and isolates (HM-1 to BM-10) were observed on growth parameters (plant height, fresh shoot weight and fresh root weight), mycorrhizal per cent colonization and sporocarp number and NPK content of tomato plants and found that all the treatments were significantly superior as compared to uninoculated control. Maximum plant height (48.4cm), shoot weight (14.63g) and root weight (4.53g) were found in isolate BM9. Hence, isolate was selected for further experiments. A negative effect was observed on the viability of different mycorrhizal species (Glomus mosseae, Glomus fasciculatum, Glomus hoi and Glomus intraradices) uncoupled from the host. After 7 months of shoot removal minimum and significant lowest viability was observed in Glomus intraradices (35.4 %) and the maximum was in Glomus mosseae (40.1 %) (2020). During 2021, minimum and significant lowest viability was observed in Glomus intraradices (32.9 %) and the highest in Glomus hoi (39.2 %). Maximum mycorrhizal population (Mycorrhizal colonization and sporocarp number), plant growth parameters (plant height, fresh weight of shoot and fresh weight of root and dry weight of shoot and dry weight of root), Mycorrhizal inoculation effect and mycorrhizal dependency was found in onion which was sequential crop after tomato as compared to without sequential crop rotation. Effect of different treatments on wilt intensity of tomato was observed in screen house conditions and maximum wilt intensity was found in Fusarium oxysporum (75.27 %) inoculation followed by Fusarium oxysporum→ Mycorrhiza (52.47 %). Wilt disease of tomato was most effectively managed (61.30 %) by combinational application of mycorrhiza, vermicompost, FYM and spent mushroom substrate mushroom substrate recession of decreased total soluble proteins and sugars and boost of total phenol was noted in F. oxysporum inoculated plants.

    Impact assessment of arbuscular mycorrhiza on chilli wilt caused by Fusarium oxysporum f. sp. capsici
    (CCSHAU, 2019) Sarita; Rakesh Kumar
    The present study was conducted to evaluave the impact assessment of arbuscular mycorrhiza on chilli wilt caused by Fusarium oxysporum f.sp. capsici. Surveys in different district of Haryana was conducted during 2017 - 2018 for mycorrhizal colonization (%), sporocarp number in soil and wilt intensity in the chilli and found that mycorrhizal colonization (per cent) ranged from 1 - 17.3 per cent and sporocarp number in soil ranged from 9 - 130. wilt intensity ranged from 0.5 - 7.9. The mycorrhizal per cent colonization and sporocarp number in soil were highest in Mahendragarh district (Ateli 17.3 % and 130 respectively), followed by Fatehabad district (Dani Binja Lamba 13.1 % and 91 respectively) and lowest in Hisar district (11.5% and 69 respectively). The maximum wilt intensity was recorded from the Fatehabad district (Bhuna, 7.9), followed by Mahendragarh (Silarpur, 7.3) and minimum from Hisar (Kharar-Alipur, 5.2). Three Glomus species were tested on chilli. Maximum plant growth parameters (Plant height, Root length, Dry weight of root and shoot), SPAD chlorophyll content, per cent mycorrhizal colonization and sporocarp number was maximum in Glomus intraradices, when 400 spores were inoculated followed by Glomus mosseae and Glomus fasciculatum. The maximum per cent disease control (57%) was recorded when F. oxysporum + G. intraradices + T. harzianum were inoculated. For the management of chilli wilt G. intraradices and T. harzianum were used with different combination. For the management of chilli wilt G. intraradices and T. harzianum were used with different combination. Maximum plant growth parameters (Plant height, Root length, Dry weight of root and shoot), SPAD chlorophyll content and NPK content was in triple inoculation (F. oxysporum + G. intraradices + T. harzianum) and minimum in F. oxysporum at 90 DAT. Different mycorrhizal species may differ in their ability to control the disease. For the desirable effect on plant growth and inducing resistance to pathogens, suitable host symbiont combination has to be found. The use of mycorrhizal fungi an effective method for disease control, mainly root and soil borne disease.

    Physiological responses for salinity tolerance in Indian mustard (Brassica juncea)
    (CCSHAU, 2017) Sarita; Sandooja, J.K.
    In this study, 15 genotypes of Brassica juncea namely RH0673, RH0725, RH1462, RH1470, RH1472, RH1501, RH1504, RH1507, RH1512, RH1514, RH1520, RH1535, RH8812, RH9304, and RH0305 which have unknown response to salinity were screened for the selection of salinity tolerant genotypes. Seeds of these genotypes were raised in plastic trays having 3kg soil saturated with 0, 8, 10, 12 and 14dSm-1 salinity salts with water. On the basis of this experiment, genotypes RH0725 and RH1512 were salinity tolerant whereas, genotypes RH1520 and RH8812 were susceptible to salinity. These four genotypes were sown in pots having 5kg dune sand saturating by 0, 8, 10 and 12dSm-1 salinity salts with water, for further investigation of physiological responses. Salinity stress affected all physiological parameters. Some physiological parameters like total chlorophyll content, chlorophyll fluorescence, photosynthetic rate, transpiration rate, protein content etc reduced due to salinity applications both at vegetative and flowering stage. However, some parameters like electrolyte leakage, MDA content, total soluble sugars antioxidant enzymes (CAT and POX) activity increased by all salinity levels both at vegetative and flowering stage. Yield and yield attributes such as no. of siliqua/plant, no. of seeds/siliqua and 1000 seeds weight were also reduced by all levels of salinity. Under salinity, minimum reduction in photosynthetic rate, total chlorophyll content, transpiration rate, total soluble proteins etc and maximum increase in osmolytes such as total soluble sugars, proline content etc were observed in genotype RH1512. So, genotype RH1512 performed very well under all salinity levels. So, it is concluded that, genotype RH1512 was more salinity tolerant where RH8812 was comparatively more sensitive towards salinity.

    Consumption pattern of maize and development of supplementary foods from QPM (Quality Protein Maize)
    (CCSHAU, 2007) Sarita; Kawatra, Asha
    The present study was undertaken to study the consumption pattern of maize in maize growing districts of Haryana i.e. Karnal and Ambala, development of supplementary food products from QPM and normal maize and to study nutritional composition of developed food products for diversifying the utilization of maize. A total of 200 families were selected from both the districts for conducting survey. A well structured questionnaire was prepared and information was collected on socio-economic status, dietary habits, food consumption pattern, maize utilization pattern i.e total production, household consumption use as animal feed, market surplus, cropping pattern, form of maize consumption etc. Various supplementary food products were developed from whole maize grains/grits/flour. They included products like Bakli, Poori, pulao, shakarpara, Dalia, Burfi, Vada and Sevian (extruded product). All the developed products were organoleptically evaluated. The results of the organoleptic evaluation of all the developed products indicated that all the products were organoleptically acceptable to the panel of judges. All products prepared by replacing cereals or legume ingredients (30:70 ratio) were also found to have more acceptable sensory values. Nutritional evaluation of acceptable products revealed that Protein, fat and Ash content of maize based sweet products like burfi, Shakarpara were observed to be higher in QPM based products than normal maize products. Crude fibre content of these products prepared from normal maize was highest and lowest in QPM based products. Contents of Starch and non reducing sugar were observed to be higher in normal maize based sweet products than QPM based products. All dietary fibre constituents were higher in QPM based traditional sweet products then those based on normal maize. It was found that preparation of various supplementary products viz. burfi, shakarpara, bakli, dalia, poorie, vada, sevian etc. from maize in combination with other cereals and legumes resulted in better nutritional profile. Therefore, replacement of wheat flour, Bengal gram flour, and refined wheat flour with maize flour for preparing various products in the diet may be beneficial. Keeping in view of the nutritional profile of QPM, the development of these products will not only diversify the uses of maize but will also be beneficial for human health especially in combating malnutrition. There is need to popularize the supplementary food products based on maize among the housewives so that they include these preparations in their daily dietaries. The increased utilization of maize will help in improving the production of maize which may indirectly help in improving the economic standards of farmers. The study also provides scope to make efforts for commercialization of the maize based products through self help groups and food industries etc.
