Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    An experiment was conducted to analyze the general soil properties, status of available macronutrients (N, P K and S) and to study the relationship between soil properties and macronutrients. Soil samples (0-15cm depth) were collected from 80 different location of Almora district of Uttarakhand. Different methods of analysis of soil were employed to know the availability of N, P, K and S. Available Nitrogen was analyzed by alkaline KMnO4 method, available phosphorus by Bray’s method, AB-DTPA method, Mehlich-3 method and Morgan method, available Potassium was analyzed by Ammonium acetate, AB-DTPA, Mehlich-3 and Morgan methods and Available Sulphur was analyzed by CaCl2 method. The color of soil samples of entire study area were, grayish brown, brown, light brown, weak red, dark brown, pale brown, light yellowish brown, light olive brown, olive yellow, olive grey, light yellowish brown, pale olive, olive grey, reddish grey and dark grey brown. The soil texture of entire study area was from coarse texture to medium texture. Soil was found to be acidic with soil pH and EC ranging from 5.15 – 6.97 and 0.012 - 0.952 dSm-1 with overall mean value of 6.26 and 0.186 dSm-1, respectively. The soils were medium to high in organic carbon content and ranged from 0.09- 1.90% with overall mean value of 0.99%. The percent organic matter content in soils ranged from 0.16- 3.27% with overall mean value of 1.71%. The percent calcium carbonate content in soils of entire study area ranged from 1.07 – 2.96% with mean value of 2.03%. The available nitrogen in soils ranged from 99.10 - 244.61 kg ha-1 with overall mean of 148.33 kg ha-1. The available phosphorus content extracted by Bray’s method, AB-DTPA method, Mehlich-3 method and Morgan method ranged from 12.43 – 22.35 kg ha-1, 11.64 - 63.62 kg ha-1, 21.35 – 55.93 and 20.13– 69.16 kg ha-1, respectively. Available potassium content ranged from 78.18 – 317.52 kg ha-1, 114.38-296.60 kg ha-1, 90.64-164.74 kg ha-1 and 97.39 - 197.57 kg ha-1, when extracted by Ammonium acetate, AB-DTPA, Mehlich-3 and Morgan methods respectively. The soil available Sulphur ranged from 10.19 - 90.58 kg ha-1 with mean value of 38.26 kg ha-1. No significant correlation was found between soil properties and macronutrients in 18 location soils. At 62 locations, Organic Carbon had significant and positive correlation with available N. and S. In sixty two location soils also showed positive and significant correlation with available nitrogen and potassium with soil pH and EC. On the basis of calculated nutrient indices, the soils under study were found to be low in extractable nitrogen, low to medium in extractable phosphorus, low to high in extractable potassium, low in calcium carbonate and high in sulfur content.

    Phytochemical examination and evaluation of pesticidal activities of Globba sessiliflora Sims (Zingiberaceae) Oleoresins
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-08) Verma, Bhawna; Ravendra Kumar
    The present study was aimed to analyse the phytochemical nature and to evaluate pesticidal activities of the oleoresins from aerial part (GSAO) and rhizomes (GSRO) of Globba sessiliflora Sims. The plant material was collected in the month of July, 2021 from Kausani, Bageshwar, Uttarakhand. The oleoresins were prepared by cold percolation method and percent yield obtained were 3.7% and 3.3% for GSAO and GSRO respectively. Both the oleoresins varied greatly in composition, the major compounds identified in GSAO were methyl linoleate (18.2 %), methyl palmitate (17.1%), β-pinene (10.5%) and phytol (10.4%), while the major compounds present in GSRO were γ-sitosterol (22.1 %), 8(17),12-labdadiene-15,16-dial (18.6%), methyl linoleate (4.9%) and methyl palmitate (4.4%). The different pesticidal activities of oleoresins were performed using standard protocols. The nematicidal activity tested against Meloidogyne incognita demonstrated higher mortality in case of GSRO than GSAO. GSRO also showed more inhibition of hatching of the eggs of Meloidogyne incognita. The oleoresins GSAO and GSRO were also tested for their insecticidal activity against the insects mustard aphid, Lipaphis erysimi (second instar nymphs) and castor hairy caterpillar, Selepa celtis (second stage larvae). In case of mustard aphid, more insecticidal activity was observed for GSRO (LC50= 154.8ppm) than GSAO (LC50= 263.0ppm), while in case of castor hairy caterpillar, more insecticidal activity was observed for GSAO (LC50= 346.7.0ppm) than GSRO (LC50= 398.1ppm). The herbicidal activity of GSAO and GSRO was assessed against radish seeds (Raphanus raphanistrum subsp. sativus) for the effects on different growth parameters such as percent germination, coleoptile length and radical length. Significant herbicidal activity was shown by both the oleoresins but more effective activity was shown by GSAO (IC50=166.4ppm) than GSRO (IC50=249.6ppm).

    Dissipation studies of Boscalid (a carboxamide fungicide) in soils of different textures
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-09) Butola, Adarsh; Srivastava, Anjana
    Boscalid [2-chloro-N-(4'-chlorobiphenyl-2-yl) nicotinamide] is a carboxamide fungicide used in variety of food crops and turf grasses. It comes under the SDHI group of fungicides which inhibit the enzyme succinate dehydrogenase ubiquinone (complex II) which is an important enzyme for energy production in respiratory chain. The dissipation studies of boscalid was performed in different textural soils at 1 and 2 μg g-1. The method of extraction of boscalid residue from soil was validated by following QuEChER’S (Quick, Easy, Cheap, Effective, Rugged and Safe) method and the quantitative analysis was done by HPLC (High performance liquid chromatography). Recovery study of boscalid was performed at two concentration of 1 and 2 μg g-1 and the recoveries obtained ranged from 80.59% to 98.97% in two soils. The dissipation rate of boscalid did not vary much in the two soils. At lower application rates (1μg g-1) boscalid dissipated to 96.12% and 97.23% upto 21st day and was below detectable limit (BDL) on 28th day at lower concentration of 1μg g-1 in both the soils. At higher application rates (2μg g-1) boscalid residue persisted upto 28th day with dissipation upto 98.24% and 98.18% in both the type of soils. It was BDL on 35th and 60th day of fungicide application. Dissipation of boscalid occurred in a single distinct phase following first order kinetics. The half life of boscalid ranged from 4.66 and 4.16 days in soil samples A and B at 1 μg g-1 and 5.22 and 4.73 d in both the soils at 2 μg g-1 application rates. Boscalid is used in various vegetable, field crops and turf grasses for controlling fungal diseases and decreasing the economic damage but since it does not persist in subtropical soils it can be safely applied at recommended dosage in crops and soils.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2022-06) Upadhyay, Pringal; Ravendra Kumar
    The present study aimed to investigate the chemical variation in essential oils composition and evaluation of biological properties of Strobilanthes species. Strobilanthes species viz. S.pentastemonoides (Nees), S. glutinosa (Nees), S. angustifrons C. B. Clarke, T. Anderson, S. attenuata (Wall. ex Nees) Jacq. ex Nees and S. tomentosa (Nees) J.R.I.Wood were collected in the month of August-January (2019–2021) at flowering stage from different location of Kumaun region, Uttarakhand. Essential oils were extracted by hydro-distillation using Clevenger type apparatus. Essential oils yield (% v/w) was found to vary from 0.006 to 0.01% in different Strobilanthes species. Essential oils isolated from different Strobilanthes species were analyses by GC-MS to check the chemical variations. Biological activities (in vitro antioxidant, anti-inflammatory and anti-diabetic) were also performed for different Strobilanthes species essential oils by using reported protocols. Fenchyl acetate was the marker molecule of Strobilanthes glutinosa oil, collected from Kill, Pithoragarh (SGPEO) and Strobilanthes angustifrons oil, collected from Kausani, Bageshwar (SABEO) in variable amount, respectively. Guaiol was the dominant constituent of Strobilanthes pentastemonoid oil, collected from Sirkuch of Pithoragarh (SPPEO) and Strobilanthes attenuta essential oil, collected from Saktipur, Champawat (SACEO) in different amount, respectively. Labda-7,13 diene-15-ol (51.84%), a diterpenoid molecule was identified as the major secondary metabolite in Strobilanthes tomentosa essential oil, collected from Kainchi Dham, Nainital (STNEO). The antioxidant activity was performed by three different methods which include DPPH radical scavenging activity, H2O2 scavenging activity and metal chelating activity. BHT and Na2-EDTA were used as standard antioxidants. Antioxidant activity of SPPEO, in terms of DPPH scavenging activity (IC50=15.32 μL/mL) and metal chelating activity (IC50= 23.29μL/mL) was found to be higher than those of the others. In terms of H2O2 scavenging activity, the highest antioxidant activity was observed for SACEO (IC50 = 21.83μL/mL). The in-vitro anti-inflammatory activity was performed by using denaturation of egg albumin protein method. Diclofenac sodium was the standard for anti-inflammatory activity. Among all tested samples, STNEO showed high anti-inflammatory activity with an IB50 value of 9.6±0.57 μL/mL. The antidiabetic activity was analysed by α-amylase inhibition assay. Acarbose was used as standard antidiabetic agent. STNEO showed significant α-amylase inhibition an IC50 value of 30.15±1.96 μL/mL. In conclusion, results revealed that all the studied essential oils possess good to moderate antioxidant, anti-inflammatory and antidiabetic properties at different dose levels, and this could be due to the differences in the composition and concentration of biological active compounds.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-07) Rahul; Srivastava, Anjana
    Nowadays, understanding the impact of the pesticide exposure is an important concern for the consumers. Chilliis the commonly used vegetable which is highly exposed to pesticide usage. The current study is aimed at investigating the effectiveness of different decontamination treatments for removal of nine commonly applied pesticides on Chilli crop. The Chilli samples were subjected to nine decontamination treatments namely washing with running tap water, soaking in lukewarm water (50-60°C), soaking in solutions of 1% NaCl, 5% NaHCO3,2% CH3COOH,0.01% KMnO4and commercial decontaminants like Veggie clean, Nim wash, and Arkaherbi wash for ten minutes every time. The extraction of all the pesticides in Chilli crop was done through QuEChER’S method and analysis of acephateand it’s metabolite methamidophos, acetamiprid, carbendazim, imidacloprid, tebuconazole, and thiamethoxamwas done by HPLC-UVwhereas that of chlorpyrifos, cypermethrin, and profenofos by GCECD. In Chilli, the results indicated that soaking in 2% acetic acid solution was significantly superior to the rest of the treatments to decontaminate all the pesticides (>50%) except profenofos when compared with other treatment solutions, whereas treatment with 1% NaCl solution proved to be the next best treatment in removal of different pesticides. Amongst commercial decontaminant solutions washing with Nim wash removed the highest percentage of pesticide residues from Chilli fruits. Acephate and it’s metabolite methamidophos, tebuconazole and carbendazim could be decontaminated well by the use of 0.01% KMnO4 solution, wherein the percent removal ranged between 79-91.37%. Similarly cypermethrin, acetamiprid, imidacloprid, chlorpyrifos and thiamethoxam residuescould be dislodged on soaking in 2% acetic acid solution ranging from 60.98 to 89.43%.Profenofos could be decontaminated to the maximum extent by dipping in commercial decontaminants like Nim wash (68.81%) and Veggie clean (68.41%) solutions where as it could be washed off only slightly by the other decontaminant solutions. The study confirms the use of simple cost-effective household solutions, to reduce the commonly applied harmful pesticides from Chilli.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-10) Neel, Shila; Srivastava, Anjana
    Now a days understanding the impact of the pesticide exposure is an important concern for the consumers. Okra and chilli are the commonly used vegetables which are highly exposed to pesticide usage. The current study is aimed at investigating the effectiveness of different processes for reduction of four commonly applied pesticides on okra and chilli crops. The okra and chilli samples were subjected to seven decontamination treatments namely washing with running tap water, soaking in lukewarm water (50-60°C), soaking in 1% NaCl, soaking in 5% NaCl, soaking in 5% CH3COOH, soaking in 5% NaHCO3 and soaking in 0.01% KMnO4. The extraction of all the pesticides in both the crops (quinalphos, profenophos ethion and lambda-cyhalothrin was done through QuEChER’S method and analysis by GC-ECD. In okra, results indicated that soaking in 5% Acetic Acid solution for 10 minutes followed by washing using tap water was more effective in reducing all pesticides tested in comparison to other treatment solutions, whereas in chilli, the treatment of soaking in 5% NaCl solution for 10 min., resulted in the maximum removal of all the pesticides in comparison to the rest of the decontamination treatments. Lambda-cyhalothrin was reduced in higher amounts by all the decontamination processes but the highest removal (97.96%) was by soaking in 5% Acetic acid. In okra the magnitude of reduction of quinalphos, profenophos, ethion and lambda-cyhalothrin was observed in the range of 48.0-95.3, 34.3-87.6, 64.2-97.8, and 40.1-97.1 percent respectively, likewise, in chilli, the magnitude of reduction of quinalphos, profenophos, ethion and lambda-cyhalothrin was observed in the range of 13.11-86.55, 7.00-92.98, 10.73-96.34 and 59.99-97.96 percent respectively. The study confirms the use of simple cost-effective household solutions, to eliminate harmful pesticides from okra and chilli crops.
