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.

    Comparision of STCR and GRD approach for fertilizer recommendation in maize (Zea mays L.) - wheat (Triticum aestivum L.) crop rotation in North Western India
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-10) Sandeep Kumar; Shrivastava, Ajaya
    A field experiment was started since 2018-19 in the D7 block of Norman E. Borlaug Crop Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar. This thesis work is presented for the year 2021-22, on a comparison of soil test crop response and the GRD approach for fertilizer recommendation in maize–wheat crop rotation. For this experiment a hybrid maize variety (P3401) grown in the kharif season of the year 2021 and a wheat variety (HD 2967) grown in the rabi season of the year 2021-22. The experiment was carried out with three replications and nine treatments in a randomized block design and used treatments were control (T1), GRD (T2), STCR target yield (inorganic mode) (T3), STCR INM mode (T4), 75% STCR dose of N (inorganic mode) + green manure (T5), 50% STCR dose of N (inorganic mode) + green manure (T6), 75% RDN + green manure (T7), 50% RDN + green manure (T8) and FYM + green manure + urd intercropping (T9). It was observed that the residual impact of green manure (Sesbania) was seen only on the wheat crop during the kharif season because the crop was grown on-site, cut and incorporated into the soil during this time period only. There was only intercropping of urd between the rows of maize crops. The grain and straw yields for each plot were recorded after harvest. The plants and soil samples were collected at the end of each cropping season and analyzed according to standard methods. The experiments revealed that both inorganic fertilizers and organic manures (FYM and green manure incorporation) had no significant impact on soil pH and EC. STCR-based approach improved the mineralization of nitrogen, the extraction of phosphorus and the extraction of potassium from the soil. There was a variation in the maize yield between 29.33 q ha-1 and 57.47 q ha-1 during kharif 2021. Wheat grain yields ranged from 28.61 q ha-1 to 49.39 q ha-1 during rabi 2021-22. The crop had higher grain yields and nitrogen, phosphorus and potassium uptake after using 100% STCR-based fertilizers with FYM @ 10 t ha-1. A higher percentage of target yield was also achieved under the STCR INM approach than under NPK alone. STCR-based treatment that included STCR INM and 75% STCR dose of N + green manure had improved soil properties. It was concluded from the present experiment that fertilizer recommendations based on the Soil Test Crop Response approach combined with organic manure assist in the management of nutrients and reduce the use of excessive fertilizers, which restores soil fertility, maintains soil health and environmental quality by reducing excessive fertilizer consumption

    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Negi, Avantika; Gangwar, S. P.
    The field study was carried out with maize crop at Norman E. Borlaug Crop Research Centre, G.B.P.U.A &T, Pantnagar during the year 2021-22 in the Department of Soil Science, Pantnagar. The experiment was laid in Randomized Block Design (RBD) and the treatments were T1: 5 kg Zn ha-1 through soil application, T2: 10 kg Zn ha-1through soil application, T3: 2.5 kg Zn through soil application + FYM 5 t ha-1, T4: 1 % Zn at knee height stage through foliar spray, T5: 1 % Zn at knee height and silking stage through foliar application, T6: Zn solubilizing bacteria solution (IFFCO - @ 3 ml Kg-1 seed) and T7: Control. The study revealed that, amongst various method of zinc application, the soil application of ZnSO4 @ 2.5 kg ha-1 along with the application of FYM (T3) and application of Zn solubilizing bacteria solution through seed treatment (T6) showed positive impact on the crop growth, yield attributing characters (with increment of 36 % zinc content in plant over control) and yield of maize crop. The yield increment in the treatment T3 and T6 were 20 % and 16 % over control. The soil application of ZnSO4 @ 2.5 kg ha-1 along with the application of FYM (T3) showed positive impact in terms of soil zinc status. The soil earlier deficient in zinc was found sufficient after harvest in terms of zinc with 33 % over control The uptake of macro as well as micro nutrient was enhanced with the treatment of soil application of ZnSO4 @ 2.5 kg ha-1 along with the application of FYM. The soil physical properties were remained unaffected with the graded levels of zinc application at various stages. The greatest net monetary returns, and benefit cost ratio were observed with soil application of Zn solubilizing bacteria solution through seed treatment (T6). The foliar application of zinc at various growth stages (treatment T4 and T5) also showed less significant (over T3 and T6) but better results over basal application of ZnSO4 (Treatment T1 and T2).

    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-07) Soni, Chhavi; Paul, Jai
    A field experiment was conducted during kharif season of 2021 at Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) for evaluation of ten rice genotypes (CNN-1,CNN-2,CNN-3,CNN-4,CNN-5,BCV-1,RASI,VARADHAN,MTU1010, T193) under varying nitrogen levels (Control, 50 % N, 100 % N). Treatments were tested in Split Plot Design with three replications keeping nitrogen levels in main plots and genotypes in sub plots. Different levels of nitrogen significantly influenced different soil properties including available nitrogen, available phosphorus , available potassium, nitrogen fractions ( ammonical and nitrate nitrogen) and total nitrogen at surface and subsurface depths of soil. Application of nitrogen at 100 % RDN resulted in significantly higher grain and straw yield over all other nitrogen levels. Similarly, significant height of plants, number of tillers m-2 at all stages of crop growth, 1000 grain weight, total nitrogen, phosphorus and potassium uptake were also found to be increased significantly up to 100 % N. The nitrogen use efficiency which includes agronomic use efficiency, partial factor productivity, physiological efficiency and recovery efficiency also found to be higher under 100 % N treatment than that of 50 % N and control. Among rice genotypes in subplot RASI recorded highest ammonical, nitrate nitrogen, total nitrogen at both depths of soil. Similarly, highest grain, straw and biological yield over other genotypes was recorded under RASI followed by CNN-4. RASI genotype also recorded higher number of tillers m-2 at maturity and highest 1000 grain weight which ultimately resulted in higher grain yield. Similarly, maximum uptake of N, P and K in grain and straw was also recorded in genotype RASI followed by CNN-4. The agronomic use efficiency, partial factor productivity and recovery efficiency was also recorded highest under RASI. From the results of this experiment, it has been concluded that different rice genotypes performed better under 100 % RDN in comparison to 50 % RDN and control. The 100 % RDN showed its superiority to improve availability of NPK, fractions of nitrogen, crop yield, uptake of nutrient and nitrogen use efficiency, while RASI followed by CNN-4 showed superiority over others in relations to soil properties, growth, yield and nitrogen use efficiency under study.

    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-08) Arya, Shreyshi; Manisha, Rani
    The experiment was conducted at N.E. Borlaug Crop Research Centre of G. B. Pant University ofAgriculture and Technology, Pantnagar, Uttarakhand during Rabi season of 2021-22 to study on saving of water, soil properties and yield in pea (Pisum sativum L.) with the use of surfactant and different nutrient inputs. Five treatments viz control (T1), vermicompost + irrigation (T2), NPK + irrigation (T3), vermicompost + irrigation with surfactant (T4) and NPK + irrigation with surfactant (T5) were tested in field condition and water use studies were done under three water table regimes W1 (30 ± 1.5 cm), W2 (60 ± 1.5cm) and W3 (90 ± 1.5 cm) in lysimeters. It is clear from the results that the treatment of vermicompost + irrigation with surfactant (T4) resulted in maximum plant height (37.0 cm), number of branches per plant (13.3), number of pods per plant (4.7), pod length (8.3 cm), number of grains per pod (8.3) and yield of green pods (110.1 q/ha) in field condition. Maximum soil organic carbon content (0.76 %), available nitrogen (254 kg/ha), infiltration rate (32.1 mm/hr) and lowest bulk density at 0-20cm (1.18 Mg/m3) and 20-40 cm (1.30 Mg/m3) were also observed under treatment T4. However, available phosphorus (21.42 kg/ha), potassium (154.80 kg/ha) and EC (0.15 dS/m) were recorded maximum under T5 treatment. The application of vermicompost and irrigation with surfactant positively influenced the yield of vegetable pea and important soil physical & chemical properties. In Lysimeter, all yield attributes and yield of vegetable pea were recorded maximum (98.29 q/ha) under the water table depth of W1 (30 ± 1.5 cm). The highest WUE of 33.41 kg/ha/mm was recorded under W3 followed by W2 (27.05 kg/ha/mm) and then W1 (26.36 kg/ha/mm).

    Water use efficiency, yield, nutrient uptake by spring maize (zea mays l.) and soil properties under different tillage and mulch practices in mollisols
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Bhatt, Kirti; Singh, Veer
    A field study was conducted in the spring seasons of 2021 at the N. E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar to study the effect of tillage and mulch practices on water use efficiency, yield, nutrient uptake by maize and soil properties in Mollisols. The experiment comprised of three tillage practices viz., conventional tillage (CT), zero tillage (ZT) and half ridge slope planting (RSP) in the main plots, while the two mulch treatments viz., no mulch and maize straw mulch applied @ 6 t ha-1 in the sub-plots tested in factorial randomized block design with 3 replications. Results showed that tillage practices significantly affected the growth, yield attributing characters, yield, nutrient uptake and soil properties. However, mulch application had significant impact on all soil properties and growth and some yield attributing characters. Among different tillage practices, maize grown on the half slope of the ridge recorded higher values of growth, yield attributes and yield of maize over other tillage practices. However, zero tillage sustained the favourable condition for most of the soil properties. Soil properties like bulk density, water stable aggregates, water holding capacity, mean weight diameter, organic carbon, mineralizable N, extractable K were higher from 6.2-7.6,4.1- 20.2, 15.3-22.3,10.5-24.9, 5.0-16.6, 7.7-29.6 and 0.5-2.4%, respectively, under ZT than CT and half RSP. However, half RSP treatment increased soil porosity, electrical conductivity and extractable P while soil pH in CT. Soil organic carbon at surface soil was 0.70 g kg-1 in ZT against 0.65 and 0.54 g kg-1 in RSP and CT, respectively. The maximum 100 grain weight (36.86 g) and grain yield (7084 kg ha-1) were produced under RSP due to the higher root weight, later emergence of tassel and silk, water use efficiency (WUE) and nutrients uptake. As compared with no mulch, application of mulch yielded 3.04% more grain yield by increasing 6.1% WUE. The combined effect of tillage and mulch practices in general non-significantly affected the growth, yield attributing characters, yield, nutrients uptake and soil properties. However, adaptation of ZT along with mulch improved the soil properties while RSP with mulch gave higher growth, yield attributing characters and grain yield (7130 kg ha-1). The saving of water was found in order of ZT with mulch (32.74%) followed by RSP with mulch and ZT without mulch (24.55%) and least under CT with mulch (8.18%). In all tillage and mulch combinations, soil organic carbon and available nutrients were found to be positively correlated with grain yield while maximum negative and significant relationships were noticed between bulk density and grain yield (-0.987*).Water use efficiency, in general had significant correlations with most of the soil properties. Application of half ridge-slope planting with mulch for growth and productivity of spring maize while zero tillage with mulch to sustain soil properties are most beneficial and can be recommended for further study of spring maize in tarai region of Uttarakhand and other sites with similar soils and climate.

    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-07) Sharma, Reeba; Gautam, Poonam
    Present study was carried out to evaluate soil health under rhizospheric and non rhizospheric zone of different fruit crops: litchi, guava, mango, pear, jackfruit, peach, plum and fallow land by collecting representative soil samples (0-20 cm depth) during Rabi 2020-2021 from Horticulture Research Center, G. B. Pant University of Agriculture and Technology, Pantnagar (29.5° N latitude, 79.3° E longitude and 243.84 MSL altitude), District U.S. Nagar (U.K.). The soil samples were analyzed for the determination of various physical, chemical and biological properties using standard procedures to work out different soil health indices: structural stability index, soil organic carbon storage, biochemical index, deterioration index, soil health index and soil quality index. Results revealed that different soil properties varied significantly under different fruit crops and soil zones. Noted range of soil properties was from 1.43 to 1.54 Mg m-3 bulk density, 31.25 to 56.30 % water holding capacity, 6.53 to 7.76 pH, 1.36 to 2.09 % organic carbon, 130.1 to 232.1 kg ha-1 available nitrogen, 21.40 to 50.46 kg ha-1 available phosphorous, 148.3 to 333.5 kg ha-1 available potassium, 0.888 to 2.27 mg kg-1 available zinc, 2.28 to 8.34 mg kg-1 available copper, 0.825 to 2.68 mg kg-1 available manganese, 7.32 to 25.72 mg kg-1 available iron, 3.31 to 6.09 x 108 cfu g-1soil total microbial population, 161.38 to 474.59 μg TPF g-1 soil 24h-1dehydrogenase, 2.64 to 4.40 mg urea g-1 soil 24h-1 urease and 139.37 to 243.76 μg PNPg-1 soil h-1 total phosphatase activities under different fruit crops. On the basis of soil health evaluation indices under rhizospheric and non rhizospheric zone of different fruit crops it was found that 1. Low risk of soil structural degradation under litchi and guava orchards (7.68 and 7.16%, respectively) 2. High soil organic carbon storage and biochemical activities under litchi orchard (59.62 Mg C ha-1 and 1498.6, respectively) 3. No deterioration under fruit orchards soil than fallow land 4. High soil health under litchi (82.50%), mango (77.50%) and guava (72.50%) fruit crops 5. High soil quality under litchi (5.07), mango (4.91) and guava (4.73). Better soil conditions were observed under rhizospheric zone than non rhizospheric zone of different fruit crops. Soil health and soil quality was also found better under fruit crops soil as compared to fallow land. Thus, an overall superiority both in terms of soil nutrient status and soil stability under fruit orchards over fallow land indicated that inclusion of horticultural crops may be an effective strategy to maintain soil sustainability and improve crop productivity.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2022-01) Bisht, Swapnil; Jai Paul
    The present experiment “Effect of Conjoint Use of Organic and Inorganic Sources of Nutrient on Soil Properties, Yield and Nutrient Uptake in Rice Crop” was carried out during kharif season of 2020 at Norman E. Borlaug Crop Research Centre of the Govind Ballabh Pant University of Agriculture and Technology, Pantnagar. The experiment was laid in RBD and replicated three times with eleven treatments. The conjoint use of inorganic and organic fertilizer for short duration influenced significantly the soil properties and crop yield. The soil aggregate stability and bulk density ranges from 16.47 to 20.83% and 1.25 to 1.35 Mg m-3, respectively. Experiment findings indicated that the conjoint use of inorganic fertilizer with organic sources significantly influences aggregate stability and non-significantly influences the bulk density. Also, the soil pH and EC ranged from 7.09 to 7.45 and 0.297 to 0.338 dSm-1, respectively, indicated that the conjoint use of organic and inorganic sources significantly influence soil pH and EC. The content of organic carbon, available N, P and K improved significantly over the control. The content of organic carbon, available N, P and K ranged from 0.51 to 1.19%, 232.48 to 345.74 kg ha-1, 6.61 to 30.71 kg ha-1 and 151.33 to 208.85 kg ha-1, respectively. The soil carbon fractions i.e. C-frac1, C-frac2, C-frac3 and C-frac4 and soil organic carbon stock improved significantly in all treatments over the control and the treatment (T6), receiving 75% wheat residue + 25% RDF + Pusa decomposer resulted significantly higher carbon fractions and organic carbon stock values than others. The treatment (T10) having 100% RDF + FYM @ 5 t ha-1 + Zn + B was found best among all the treatments which improves the crop yield, nutrient use efficiencies, nutrient status of soil and maintain soil fertility level. It is concluded from this study that the conjoint use of inorganic fertilizer and organic sources significantly improves the soil physical and chemical properties, nutrient status, crop yield and nutrient use efficiencies for long term.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2022-06) Adhikari, Rupal; yagi, Arvind Kumar T
    The present experiment “Effect of varying sources and levels of boron on potassium, calcium and magnesium uptake and yield of rice (Oryza sativa L.). was carried out during the kharif - 2021 at the E1 block of Norman E. Borlaug Crop Research Centre of the Govind Ballabh Pant University of Agriculture and Technology, Pantnagar. Two sources of boron, borax and boric acid at 0.11% and 0.22% levels of B were applied through foliar sprays at 30 DAT and 60 DAT. The experiment was laid in RBD and replicated three times with ten treatments. The initial soil sample had 0.40 mg kg-1 B, 145.45 mg kg-1 Ca and 12.5 mg kg-1 Mg. The foliar spray of borax and boric acid at different levels significantly increased the dry matter accumulation, crop yield and yield attributes. The content and uptake of B, K, Ca and Mg also, significantly improved over the control on application of different sources and levels of B. The maximum B uptake in grain and straw (16.00 g ha-1 and 63.13 g ha-1); K uptake in grain and straw (17.63 kg/ha and 161.27 kg/ha) and Ca uptake in grain and straw (4.08 kg ha-1 and 21.90 kg ha-1) were observed in treatment T6 (0.22% B through borax source with two sprays). Whereas, maximum Mg uptake in grain and straw (2.36 kg ha-1 and 15.57 kg ha-1) was observed in treatment T7 (0.11% B through Boric acid with one spray). The treatment (T6 ) having 0.22% B (Borax) with two sprays, in general, was found best among all the treatments which improved the dry matter accumulation, crop yield, yield attributes, nutrient content and nutrient uptake in rice crop. It is thus concluded from this study that the use of varying sources and levels of boron significantly improves the crop yield, yield attributes, nutrient content and nutrient uptake in rice crop.

    Effect of sulphur and boron on nutrient uptake and yield of urd bean-toria grown in mollisol
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2022-07) Maurya, Rajani; Pachauri, S.P.
    A field experiment on “EFFECT OF SULPHUR AND BORON ON NUTRIENT UPTAKE AND YIELD OF URD BEAN-TORIA GROWN IN MOLLISOL” was conducted at E1 block of Norman E. Borlaug Crop Research Centre, during Kharif and Rabi Season of 2021-22 and laboratory work was conducted in micronutrient laboratory, Department of Soil Science, College of Agriculture, G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand. The soil of the experimental site was sandy loam in texture with pH of 6.85 and EC of 0.22 dSm-1, medium in organic carbon (0.51 %), low in mineralisable nitrogen (184.98 kg ha-1), medium in available phosphorus (10.96 kg ha-1) and potassium (190.40 kg ha-1). It was sufficient in available S (11.40 ppm), DTPA extractable Fe (13.27 ppm), Mn (4.26 ppm), Cu (0.56 ppm) and Zn (0.57 ppm) but it was deficient in hot CaCl2 extractable B (0.385 ppm). The experiment was laid in randomized block design, with 3 levels of boron (0, 1 and 2 kg B ha-1) and 4 levels of sulphur (0, 20, 40 and 60 kg S ha-1) and there were 4 replications of each treatment. Urd bean (cv. Pant Urd 31) and a residual crop of Toria (cv. Uttara) were taken as test crops. Recommended dose of fertilizers were applied for both, Urd bean as well as Toria crop, as basal application. Basal doses of abovementioned boron and sulphur levels were applied only to Urd bean crop and its residual effect was seen in succeeding Toria crop. Application of B at 1 kg ha-1 and 2 kg ha-1, significantly, increased grain yield of Urd bean crop by 11.58 % and 19.47 %, respectively, as compared to control. These boron doses were also significant in enhancing nutrient (S, B, Fe, Mn, Cu and Zn) uptake by Urd bean crop, as compared to control. Residual effect of these boron doses, also, significantly increased grain yield and nutrient (S, B, Fe, Mn, Cu and Zn) uptake of succeeding Toria crop, as compared to control. Application of S at 20 kg ha-1, 40 kg ha-1and 60 kg ha-1 significantly increased grain yield of Urd bean crop by 11.05 %, 20 % and 17.89 %, respectively, as compared to control. These sulphur doses were also significant in enhancing nutrient (S, B, Fe, Mn, Cu and Zn) uptake by Urd bean crop, as compared to control. Residual effect of these sulphur doses, also, significantly increased grain yield and nutrient (S, B, Fe, Mn, Cu and Zn) uptake of succeeding Toria crop, as compared to control. Since, there is no significant difference between 1 kg B ha-1 and 2 kg B ha-1 and also between 40 kg S ha-1 and 60 kg S ha-1, with respect to grain yield and nutrient uptake of Urd bean-Toria crops, application of B at 1 kg ha-1 and S at 40 kg ha-1 is advisable. Post-harvest fertility analysis of soil revealed that there was improvement in nutrient status of soil.
