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.

    Soil test crop response based fertilizer requirement in combination with fym and biofertilizers for wheat
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-12) Phutela, Sanjam; Gautam, Poonam
    Field experiments were conducted as per technical programme of AICRP on STCR in B2 block of Norman E. Borlaug Crop Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar, (290 N latitude, 79 0 28’ E longitude and 243.84 meters above MSL), in rabi season 2018-19 to work out soil test crop response based fertilizer requirement in combination with FYM and biofertilizers for targeted yield of wheat. Prior to test crop experiment, a soil fertility gradient experiment was conducted during kharif 2018 by dividing the experimental field into three equal strips and applying graded doses of fertilizer nutrients and exhaust crop rice was grown to create soil fertility gradient artificially. Test crop wheat was grown during rabi2018-19, after dividing each strip in 24 plots (21 treatments + 3 controls). Wheat crop response to selected combinations of three levels of organics (0, 5 t FYM ha-1 and 5 t FYM ha-1+Bf ), four levels of nitrogen (0, 75, 150 and 225 kg N ha-1), four levels of phosphorus (0, 30, 60 and 90 kg P2O5 ha-1) and four levels of potassium (0, 20, 40 and 60 kg K2O ha-1) in strips of varied fertility was studied. The value of soil organic carbon, alkaline KMnO4-N, Olsen’s-P and NH4OAc-K ranged between 0.559 to 0.824 percent, 112.90 to 238.34 kg ha-1, 10.60 to 27.79 kg ha-1 and 90.16 to 164.64 kg ha-1, respectively before the test crop experiment on wheat. Grain yield of wheat varied from 10.23 to 57.95 q ha-1. Total uptake of N, P and K by wheat ranged from 18.45 to 160.68 kg N ha-1, 2.21 to 18.05 kg P ha-1and 16.24 to 121.97 kg K ha-1. Nutrient requirement to produce one quintal grain yield of wheat was 2.42 kg N, 0.278 kg P and 1.89 kg K. Per cent contribution of N, P and K from soil was 17.62, 18.21 and 19.14, respectively. Per cent contribution of N, P and K from FYM was 20.11, 13.62 and 32.31, respectively. Whereas from FYM + Bf it was 25.31, 15.48, and 39.20, respectively. Per cent contribution of N, P and K from fertilizer was 48.73, 34.73, 212.50, respectively. Per cent contribution from combined use of fertilizer and FYM was 49.12, 37.10 and 218.59 for N, P and K, respectively. Per cent contribution of N, P and K from applied fertilizer with FYM +Bf was 62.32, 38.88 and 266.68, respectively. Fertilizer nutrient prescription equations for targeted yield of wheat were developed without FYM, with FYM and with FYM +Bf and it was found that for a particular yield target fertilizer nutrient requirement decreased with increasing soil test values, however for a particular soil test value nutrient requirement increased with increasing yield targets. Application of FYM or FYM+ biofertilizer reduced the fertilizer nutrient requirement for the crop. The findings of present study may be used for fertilizer nutrient prescription for wheat in similar type of soils and climate after its verification at farmer’s fields.

    Influence of different agroforestry tree species on soil properties and their potential for carbon sequestration in tarai region of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-11) Melkani, Suraj; Singh, Veer
    A field study was carried out during 2019-2020 at Agroforestry Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, to study the influence of different agroforestry tree species on soil properties and their potential for carbon sequestration in tarai region. The experiment comprised of nine agroforestry tree species viz., Anthocephalus cadamb, Pterospermum acerifolium, Delonix regia, Terminalia chebula, Chukrasia tabularis, Dillenia indica, Bambusa vulgaris, Lagerstroemia indica and Pithecellobium dulce along with a control in randomize block design with three replications. Soil samples were collected prior to the commencement of the monsoon season at 0-15 and 15-30 cm depth. All soil properties were significantly affected by the tree plantations and except bulk density, pH and electrical conductivity of soil all other parameters decreased at 15-30 cm depth of soil compared to 0-15 cm. There was slight decrease in the pH of soil under tree covers, whereas no appreciable change in EC was observed. Compared with control (fallow land), all the soil properties found to be improved under different tree covers at both the depths. Among the different agroforestry tree species, Bambusa vulgaris planted soil showed the higher values of most of the soil properties however lowest values were found under other tree species. Different agroforestry tree species stored 47.18-101.77, 2.39-6.43 and 19.10-35.21 kg ha-1 more available N, P and K, respectively, over the fallow land at soil surface layer where maximum accumulation was found with Bambusa vulgaris for available N and Anthocephalus cadamba for available P and K. Very labile carbon fraction was observed about four and two times higher than less labile and labile and non labile carbon fraction, respectively, where highest amount of non labile carbon fraction was obtained under Dillenia indica plantation soil while other carbon fractions under Bambusa vulgaris plantation at both soil depths. Soil microbial biomass carbon, soil organic carbon content, SOC stock, carbon sequestration rate were higher under Bambusa vulgaris which was 45.08-149.21 μg g-1 of soil, 0.52-3.08 g kg-1 soil, 0.66-3.55 Mg C ha-1 and 0.098-0.586 Mg C ha-1 yr-1, respectively, more than other treatments. Compared to the initial level of 16 years back, available N, P and K, soil organic carbon content and SOC stock in terms of per cent were found to increase and was in the order of available P > SOC content > available N > available K > SOC stock. All the correlations between the soil properties in general were observed as significant. Highest significant positive and negative correlations were observed between SOC and SOC stock (0.991**) and soil bulk density and available N (-0.955**), respectively. Therefore, it is evident from the present study that agroforestry is a suitable land-use system in improvement of soil carbon storage, carbon sequestration as well as for the overall improvement of soil health through improvement in soil properties. The adaptation of Bambusa vulgaris in the agroforestry plantation system in tarai region may be beneficial.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-10) Saini, Vibha; Singh, Sobaran
    A field experiment was conducted during the year 2019-20 at D7 plot of Norman E. Borlogue Crop Research Centre of The G.B. Pant University of Agriculture and Technology, Pantnagar (290 N latitude and 79029’ E longitude), as per the technical programme of All India Coordinated Research Project on Soil Test Crop Response Correlation. The experiment was conducted in two phases. In the first phase soil fertility gradient was developed by dividing experimental field into three strips and applying graded doses of fertilizers in them (Strip I (no fertilizer), Strip II ( recommended fertilizer doses) and Strip III ( double to that of recommended fertilizer doses) and growing of exhaust crop of Sorghum. In the second phase i.e. next season test crop Mustard (Brassica juncea L.) was grown by dividing each strip in 24 plots having 21 treatments and 3 controlled plots. Response var. Pant Rya-20 of selected combinations of three levels of FYM (0, 5 and 10 t ha-1), four levels of nitrogen (0, 90, 120 and 150 kg ha-1), four levels of phosphorus (0, 40, 60 and 80 kg P2O5 ha-1) and four levels of potassium (0, 20, 40 and 60 kg K2O ha-1) at different fertility levels of mustard were studied. The values of the Alkaline KMnO4 extractable N, Olsen’s P and neutral normal Ammonium Acetate extractable K in the experimental field ranged between 67.2 to 128.8 kg ha-1 , 33.75 to 101.95 kg ha- 1 and 108.86 to 292.88 kg ha-1, respectively. The total nitrogen, phosphorus and potassium content of grain in experimental field ranged from 2.56 to 3.08, 0.56 to 0.91, 0.44 to 0.90 percent, respectively. The total nitrogen, phosphorus and potassium content in stover ranged from 1.26 to 1.99, 0.04 to 0.37, 0.39 to 1.17 percent, respectively. The total N, P and K uptake of mustard ranged between 81.13 to 147.62, 11.41 to 72.36 and 29.15 to 76.61 kg ha-1, respectively. In the present investigation the total grain yield ranged from 8.67 to 17.78 q ha-1 and total stover yield from 30.78 to 70.66 q ha-1.The percent protein content and oil content of experimental field ranged from 18.3 to 30.09 and 18.98 to 42.09, respectively. The nutrient requirement for production of one quintal of grain yield of mustard was found to be 8.03 kg nitrogen, 1.29 kg phosphorus and 3.49 kg potassium. Percent contribution of nitrogen, phosphorus and potassium was 113.6, 26.8 and 22.9, respectively, from soil, whereas from other sources as FYM was 26.8, 36.4 and 7.4 percent, respectively. Percent contribution of nitrogen, phosphorus and potassium without FYM was 15.0, 24.7 and 55.7, respectively and with conjoint use of chemical fertilizer with FYM was 15.1, 28.2 and 60.8 percent, respectively. Fertilizer prescription equations developed with the help of basic data with FYM were FN = 52.96 T – 7.49 SN – 1.77ON, FP2O5 =10.54T – 2.18 SP – 2.95 OP, FK2O = 6.93T – 0.46 SK – 0.12 OK and without FYM were FN = 53.24 T –7.53 SN, FP2O5 = 12.00 T – 2.48 SP, FK2O = 7.58 T – 0.49 SK. Coefficient of quadratic multiple regression (R2) was found good fitted (0.579**) between total grain yield, soil test values, added fertilizers and interaction between soil and fertilizer. Maximum response to mustard obtained at 120 kg N, 40 kg P2O5 and 20 kg K2O ha-1. The grain yield of mustard was significantly correlated with applied N (0.477**), P (0.558**) and K (0.397**) and with the uptake of nitrogen (0.348**), phosphorus (0.307**) and potassium (0.493**). There is no consistent trend on protein and oil content by application of fertilizer. Findings from present study can successfully utilized for the larger parts of Tarai region of Uttarakhand as effective guide for efficient and balanced fertilizer recommendation to mustard.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-12) Pant, Chayan; Dwivedi, G.K.
    A field study was carried out during 2019-2020 at Medicinal & Aromatic Plants Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, to study the physico-chemical and biological properties of soils, carbon pools and carbon stock under selected multipurpose tree species in Mollisol of Tarai region of Uttarakhand. The experiment comprised of ten agroforestry tree species viz., Tejpatta(Cinnamomum tamala), Arjun(Terminalia arjuna), Bael(Aegle marmelo), Sindhuri(Bixa orellana), Bakain(Melia azedarach), Baheda(Teminalia belliricica), Kadamb(Neolamarckia cadamba), Rudraksh Elaeocarpus ganitrus), Pakad(Ficus virens), Harad(Terminalia chebula) along with a control in randomize block design(RBD) with three replications. Soil samples were collected in the month of September - October at 0-15 and 15-30 cm depth. All soil properties were significantly affected by the tree plantations bulk density was lower under agroforestry system as compared to control. There was slight decrease in the pH of soil under tree covers, whereas no appreciable change in EC was observed. Compared with control (no tree land), all the soil properties found to be improved under different tree covers at both the depths. Different agroforestry tree species stored, 169.25 to 196.13, 11.72 to 22.48 and 157.52 to 173.19 kg ha-1 higher available N, P and K, respectively, over the control at soil surface layer where maximum accumulation was found with Tejpatta for available N and Kadamb for available P and Baheda for K. Very labile carbon fraction was observed to be higher than labile and less labile and non labile carbon fraction, respectively. Under MTP based agroforesty soil microbial biomass carbon, soil organic carbon content, SOC stock, which were 286.59 to 255.06 μg g-1 of soil, 0.81 to 0.92%, 15.46 to 17.10 Mg C ha-1, respectively, higher than other treatments. Significant and positive correlation was observed between organic carbon and biological properties. All the correlations between the soil organic carbon and carbon fraction were significant and positive except non labile fraction which had significant and negative value of correlation coefficient. Therefore, it is evident from the present study that multipurpose tree species based agroforestry is a suitable system for improvement of soil in terms of carbon sequestration, microbial biomass and enzymes as well as availability of the nutrients for overall improvement of soil health thus this system is recommended for bioremediation of the waste and degraded lands in different agroclimatic regions.

    Characterization of biochars and use of a biochar as source of macronutrients
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-09) Saxena, Abhishek; Srivastava, P.C.
    A pot experiment was conducted in the nethouse of Department of Soil Science, G.B.P.U.A.&T., Pantnagar to study the effect of graded levels of chemical fertilizers and biochar on dry matter yield, nutrient concentration and uptake by Oat (Avena sativa L.) and soil properties. Treatments imposed were combination of three fertilizer doses (0, 75 and 100% RDF) and five rates of biochar application rates (equivalent to 0, 0.5, 1.0, 2.5 and 5.0 t/ha)in a two factorial completely randomized design with three replications. The experiment was carried out by selecting Fodder Oat (variety UPO 212) crop which was harvested sixty days after sowing. The present study revealed that application of 100% RDF and 5 t/ha biochar gave the higher dry matter yield of the fodder Oat crop. The application of the fertilizer doses although increased the N concentration in plants but it was declined by increasing the biochar dose. Phosphorus concentration in the plant was however unaffected by the application of biochar. Both the biochar and fertilizer application significantly increased the K concentration in plants. Total uptake of N, P and K by plants were the highest under the treatment receiving 100% RDF + 5 t biochar/ha. The soil after the experiment showed lower pH and elevated EC on fertilizer and biochar application. The soil organic C also showed a significant rise only by the application of the biochar doses. Soil extractable N was found to increase significantly with fertilizer application and higher biochar doses only. The biochar application failed to influence soil extractable P content. Soil extractable Kincreased significantly with the application of high biochar dose. Thus, biochar can be considered as a good soil amendment to be used conjointlywith fertilizers which can supplement the crop yield and improve the soil quality.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-09) Prajapati, Aashish; Pachauri, S.P.
    An investigation was carried out to analyze the general soil properties and extractable macro- (N, P, K, Ca, Mg, S) and micro-nutrients (Zn, Cu, Fe, Mn, B, Mo) in the soils of Tehri Garhwal district and to study the relationships between general soil properties and soil extractable nutrients. Surface (0-15 cm) soil samples (n= 300) were taken from the nine developmental blocks of Tehri Garhwal. In the soils of Tehri Garhwal district, the soil texture was ranging from sandy loam to silty clay loam, soil pH (1:2 soil- water suspension) varied from 4.55-8.17, electrical conductivity (EC) ranged from 0.099-0.931 dSm-1 and soil organic carbon content varied from 3.09-10.68 g kg-1 soil. Alkaline KMnO4 extractable N varied from 123.2-226.8 mg kg-1soil, Olsen’s and Bray’s extractable P content ranged from 9.6-92.1 mg kg-1 soil. 1 N Neutral ammonium acetate extractable K, Ca and Mg varied from 44.5-296.7 mg kg-1 soil, 50 - 3550 mg kg-1 soil and 30 - 1560 mg kg-1 soil, respectively. Calcium chloride (0.15%) extractable S varied from 6.8-58.1 mg kg-1 soil. The DTPA extractable Zn, Cu, Fe, Mn varied from 0.20-16.30 mg kg-1 soil, 0.25-11.03 mg kg-1 soil, 0.39-78.0 mg kg-1 soil and 0.29-61.37 mg kg-1 soil, respectively. Hot water soluble B ranged from 0.30-3.60 mg kg-1 soil and ammonium oxalate (pH 3.3) extractable Mo varied from 0.07-0.52 mg kg-1 soil. The correlation study between soil properties and nutrient content revealed that soil pH had a significant and positive correlation with K, Ca, S, Zn, Cu and B. Soil EC had shown a significant and positive correlation with P, K, S, Zn, Cu and B. Soil organic carbon had a significant and positive correlation with N and P. According to the calculated nutrient indices (N.I.), the soils of Tehri Garhwal district were medium in extractable N, but high in rest of the nutrients (P, K, Ca, Mg, S, Zn, Cu, Fe, Mn, B and Mo).
