Isolation and characterization of lactic acid bacteria from ethnic fermented sour beverages (neeragaram) using traditional red rice varieties

Paper ID- AMA-02-09-2022-11656

Neeragaram (fermented sour beverage) is a traditional energy drink of Tamil Nadu and is considered to contain a variety of beneficial bacterial species. The purpose of this study was to isolate and identify bacteria from samples of ethnic fermented sour beverages, particularly lactobacillus species. The red rice varieties of Tamil Nadu have been chosen for developing the beverages. The samples were ADT 43 as control beverage, mapillai samba as treatment 1 and karungkuruvai as treatment 2 for developing fermented sour beverages. Three bacterial isolates, Isolate 1, Isolate 2 and Isolate 3 were isolated from fermented sour beverages and identified using morphological and biochemical assays. The two isolates were gram-positive, non-motile, round-shaped bacteria. The isolated bacteria were examined with multiple media including Mannitol Salt Agar, MacConkey Agar, EMB Agar, TSI Agar, Simmons Citrate Agar, Urea Agar, BSA, and Starch Agar with Catalase assay for biochemical characterization. Both morphologically and biochemically, the isolates have been identified as Leuconostoc mesenteriodes. By using the disc diffusion method as well as twelve different antibiotics, the isolates were further evaluated for their antibiotic sensitivity. Three of the antibiotics aztreonam, ampicillin and penicillin were all resistant to the isolated bacteria, whereas four of the drugs imipenem, ciprofloxacin, rifampicin and doxycycline were all susceptible. According to this study, it can be concluded that Leuconostoc mesenteriodes could be found in the ethnic fermented sour beverages which acts as a probiotic source to heal many stomach-related disorders.

Impact of weather variables on development of charcoal rot disease in different sowing dates of sesame

Paper ID- AMA-02-09-2022-11655

Sesame (Sesamum indicum L.) is an economically important oilseed crops worldwide. Charcoal rot disease incited by Macrophomina phaseolina (Tassi) Goid. is one of the most destructive disease of sesame and causes heavy losses annually. Environmental factors play an important role for development of disease at different growth stages of the crop. Weather factors play a major role in activation, growth and multiplication of the pathogen and subsequently disease development. Time of pathogen attack and progression of disease in relation to prevailing weather conditions is necessary for prediction of disease occurrence and their management. Epidemiological studies showed the onset of charcoal rot varied in sesame varieties HT 1 during different dates of sowing. Among three dates of sowing, the maximum disease incidence was recorded in early sown crop followed by mid sown and minimum in late sown crop in consecutive two years. The quantitative relationship between charcoal rot disease progressions and weather factors on sesame varieties during different dates of sowing revealed that disease incidence was positively correlated with maximum temperature, evaporation and sunshine hours.

Productivity, Profitability and Water Use Efficiency of Sweet corn (Zea mays L. saccharata) as Influenced by Irrigation Scheduling

Paper ID- AMA-01-09-2022-11652

This field study was conducted at Research Farm of AICRP for Dryland Agriculture at College of Agriculture (RVSKVV), Indore (MP) during the rabi 2019-20 and 2020-21. Irrigation scheduling (IW: CPE) consisted three different level viz., 0.6 IW: CPE, 0.8 IW: CPE and 1.0 IW: CPE with 6 replications in Randomized Block Design (RBD). Irrigation was applied through drip system having inline emitter of 4 lph (Litre per hour). Results revealed that among the irrigation scheduling, 1.0 IW: CPE recorded the taller plants (188.70 cm), maximum dry matter/plant (179.50 g) and number of leaves/plant (12.70) which was followed by 0.8 IW: CPE. Similarly, irrigation at 1.0 IW: CPE recorded the highest values of number of cobs/plant (2.67), cob length (29.5 cm) and weight of cob without husk (311.90 g) followed by 0.8 IW:CPE and 0.6 IW:CPE. 1.0 and 0.8 IW: CPE scheduling increased green cob yield by 10.9 and 9.3 per cent over 0.6 IW: CPE scheduling. Among the irrigation scheduling, 0.8 IW: CPE gave maximum net returns of ₹255796/ha and B:C ratio of 5.73. The maximum WUE (38.41 kg/ha-mm) followed by 47.32kg/ha-mm and 57.70 kg/ha-mm were observed in 1.0 IW:CPE, 0.8 IW:CPE and 0.6 IW:CPE, respectively. Harvested rainwater in the farm pond can be used for high remunerative crops i.e. sweet corn for obtained the better profit. Hence, it is concluded that for getting higher production and net returns from rabi sweet corn can be achieved by adopting proper irrigation scheduling from harvested rainwater.

Soil And Leaf Macro-Nutrients Status In Mango (Mangifera indica L.) cv. Dashehari Orchards Under Samba District Of Jammu Region

Paper ID- AMA-30-08-2022-11647

Based on uniformity in respect of age and tree vigor, 22 representative orchards were selected and “Dashehari” variety of mango was selected for study. Soil (0-30, 30-60 and 60-90 cm depths) and plant (leaf) samples collected from mango orchards were analyzed for physico-chemical properties (pH, EC, OC) and macro-nutrients (N, P, K, Ca, and Mg, S). The Organic carbon contents were medium to high. The per cent coefficient of variations found high in soil and plants could be due to variations in parent material and orchard management practices. Electrical conductivity was positively and significantly correlated with Potassium, Calcium and Magnesium and Organic carbon with Calcium and Magnesium. Available Phosphorus exhibited positive and significant relationship with their respective leaf nutrient contents. Soil samples were collected from three depth of soil viz., 0-30cm, 30-60 cm and 60-90 cm and analyzed for various physico- chemical properties and nutrient status. Leaf and fruit samples were also collected from the same orchards and analyzed for nutrient content, quality parameters and yield. These mango orchards have shown variation in soil pH 6.24-7.42, Electrical conductivity 0.05-0.27 ds/m, Organic carbon (0.21-1.90 %) from surface layer 0-30 cm, pH 6.30- 7.46 and 6.33-7.48, Electrical conductivity 0.04- 0.25ds/m and 0.03-0.24 ds/m and Organic carbon (0.18- 1.86 %) and (0.15-1.84%) from the sub- surface layer 30-60 cm and 60-90 cm. Nitrogen (107.10-298.26), (75.60-282.63) and (57.80-280.15) kg ha-1 from the surface and sub- surface of the soil layers. Phosphorus (7.60-22.90), (6.90-20.00) and (6.20-18.42) kg ha-1 Potassium (95.10-224.23), (90.00-217.19) and (79.34-210.00) kg ha-1 Calcium (4.02-6.35), (4.00-6.32) (4.00-6.29) [c mol (p+) kg]-1 from the soil depth 0-30, 30-60 and 60-90 cm, Magnesium (2.18-3.32), (2.16-3.28) (2.14-3.28) [c mol (p+) kg]-1 and Sulphur (12.60-19.74), (10.40-17.90) and (9.80-16.95) kg ha-1. The leaf nutrients ranged Nitrogen (1.10-2.22%), Phosphorus (0.11 -0.21%) Potassium (0.19-0.41%), Calcium (1.8-2.24 %), Magnesium (0.42-0.82 %) and Sulphur (0.04-0.25 %) respectively.

Residual pattern of imidacloprid and its metabolites in different soil types

Paper ID- AMA-29-08-2022-11645

Continuous and ever-increasing use of imidacloprid for the control of sucking pests, chewing beetles and soil insects, leads to diverse tribulations in the environment. The metabolites formed after degradation may have greater insecticidal and mammalian toxicity. The degradation studies in soil are very imperative to study the evaluation of pesticides and its metabolic products in the environment. Due to very limited information regarding dissipation behavior and its metabolic degradation of imidacloprid in soil, the present study was undertaken to estimate the dissipation pattern of the parent compound imidacloprid and its metabolites in different types of soil. Different types of soil i.e. sandy loam, loamy sand and clay loam soil were collected from different geographical locations of Punjab. Each type of the soil samples were treated with different concentrations of imidacloprid i.e. 100, 200 and 400 mg/kg. The samples were maintained at 25 ± 2°C in laboratory. After 7 days of treatment with 100 mg/kg imidacloprid, the total residues of imidacloprid and its metabolites for sandy loam, loamy sand and clay loam soil was reported to be 65.39, 68.96 and 69.99 mg/kg, respectively. Sandy loam soil type showed greater dissipation behaviour of imidacloprid followed by loamy sand and clay loam soil. Even after treatment with high doses of imidacloprid, traces of metabolites residues such as 6-chloronicotinic acid, nitroguanidine, olefin, nitrosimine, urea and 5-hydroxy were detected.
