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.

    Effect of varying levels of boron and sulphur on yields and nutrient uptake of linseed and sunflower grown in a mollisol
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-12) Bungla, Prerna; Pachauri, S.P.
    The laboratory and greenhouse experiments were conducted in the micro-nutrient Laboratory and net house of Department of soil science, College of agriculture, GBPUAT, Pantnagar in the year of 2018-2019 to study the leaching behavior of B and S in the presence of either nutrient in soils of varying textures. In pot culture experiment, the effect of B and S application on yields, nutrient concentration and uptake of B and S by linseed and a residual crop of sunflower. Two soils of different textures i.e. sandy loam and clay loam were collected from different depths (0-15, 15-30, 30-45, 45-60 and 60-90 cm) in NBCRC, Pantnagar. These soil samples were packed depth-wise in plastic pipes of 1 inch diameter and 110 cm length. All columns were packed with slightly moist soil at natural bulk density. The lower most pipe was covered with a perforated polythene sheet tied with tight rubber band. Boron and S sources were added as borax and ammonium sulphate (2 mg B kg-1 and 60 mg S kg-1) to the uppermost layer of soil. Soil columns were subjected to 6 cm irrigation at specified time intervals. Boron and sulphur were analyzed in the percolated water samples every 24 h until leaching stopped. Relatively higher amounts of B were lost from the sandy loam soil than clay loam soil and S application delayed the leaching loss of B in sandy loam soil. The kinetics of B and S losses in both the soil could be satisfactorily accounted by a first order kinetics. Pot culture experiment was laid out in a factorial completely randomized design with combinations of six levels of boron (0, 0.5, 1.0, 1.5, 2.0 mg B kg-1 soil and 2 foliar sprays of 0.2% borax at 30 and 45 DAS) and six levels of sulphur (0, 10, 20, 30, 40 and 60 mg S kg-1 soil) with three replications. Linseed (cv. Neelum) and a residual crop of sunflower (cv. Shresta) were taken as test crops and all the treatments were basally applied to linseed only. Two foliar sprays of 0.2% borax were done in sunflower crop at 30 and 45 DAS. The highest total dry matter (6.45 g pot-1), seed yield (2.30 g pot-1), stover yield (4.16 g pot-1), S concentration, B uptake and S uptake was observed under a treatment combination receiving 2 mg B and 60 mg S kg-1 soil. The highest B concentration in seeds and stover of linseed was observed under a treatment combination receiving foliar spray of B and 60 mg S kg-1 soil. The highest total dry matter (48.81 g pot-1), seed yield (13.69 g pot-1) and stover yield of sunflower (35.12 g pot-1) was recorded under a treatment combination receiving 2 mg B and 60 mg S kg-1 soil applied to linseed crop. The highest B concentration in seeds and stover and highest concentration of S in stover of sunflower was noted under a treatment combination receiving foliar spray of B in sunflower and 60 mg S kg-1 soil applied to linseed crop. The highest B uptake of sunflower was recorded under a treatment combination receiving two foliar sprays of 0.2% borax and 60 mg S kg-1 soil applied to linseed crop. The highest S uptake by sunflower was observed under a treatment combination receiving 2 mg B and 40 mg S kg-1 soil applied to linseed crop.

    Comparison of STCR approach with general recommendation of fertilizer method in maize (Zea mays L.)- mustard (Brassica juncea L.) crop rotation grown on mollisol of tarai region of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-11) Mahara, Prashant; Gangwar, S.P.
    A field experiment was conducted during 2020-21 at D7 Block of Norman E. Borlaug Crop Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar. The experiment consisted of two trials, viz. hybrid maize var. (P3401) grown in kharif season in the year 2020 and hybrid mustard var. (PR20) grown in rabi season in the year 2020-21. The experimental site was divided into 7 treatments and 3 replications, for a total of 21 plots in randomized block design (RBD).The treatments comprised of control, farmer practices, general recommended dose, targeted yield with varying levels of nitrogen, phosphorus, potassium and in few treatments farm yield manure (FYM).The aim of this experiment was to compare the STCR approach with general recommendation of fertilizer method in maize-mustard crop rotation. Response of maize and mustard crop to both the approaches were compared as soil fertility status, yield, nutrient uptake and economic impact. The experiment revealed that the chemical properties viz. pH, EC, organic carbon, available nitrogen, phosphorus and potassium was significantly affected due to fertilizers and FYM application and recorded maximum in treatment T7 i.e., target yield + 5t ha-1 FYM in both crops. The nutrient uptake and yield were also found significantly higher in T7 as compared to general recommendation dose (GRD) and control. The cost of cultivation and gross return were maximum in treatment T7 in both maize and mustard crop. But the net return was maximum in treatment T5 in both the crops. The benefit cost ratio in maize crop was highest in treatment T5 i.e., target yield 2 (50 q ha-1) which was 5.27, while in case of mustard crop, the highest benefit cost ratio 3.88 was recorded in treatment T4 i.e., target yield 1 (15 q ha-1). From this experiment it has been concluded that integrated use of NPK fertilizer with FYM based on STCR approach not only gave higher maize and mustard yield but also improve and sustain the soil fertility. But from the economic point of view the treatment with inorganic fertilizers alone perform better.

    Use of STCR approach for optimization of integrated nutrients recommendation to obtain better growth and yield of urd (Vigna mungo L.) grown in mollisols of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-10) Choudhury, Priyanka; Srivastava, Ajaya
    A field experiment was conducted during 2019-2020 at the D7 Block of Norman E. Borlaug Crop Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar. The aim of this conducted experiment under AICRP-STCR was to develop fertilizer adjustment equation for computing required nutrient doses to achieve targeted yield of Urd. Response of urd to the selected combination of three levels of FYM (0, 5 and 10t ha-1), four levels of each of Nitrogen (0, 10, 20 and 30kg ha-1), Phosphorus (0, 25, 50 and 75kg ha-1) and Potassium (0, 15, 30 and 45kg ha-1) were studied. Organic carbon, available nitrogen, phosphorus and potassium status of the experimental plot was studied. It was found that to produce one quintal of urd grain 3.24 kg of nitrogen, 0.79 kg of phosphorus and 2.73 kg of potassium were needed. Percent contribution of N, P and K was 26.77, 17.44 and 21.27 from soil, 66.94, 41.21 and 51.64 from chemical fertilizer solely, 10.25, 7.23 and 5.86 from FYM and 92.37, 65.72 and 52.77 from combined use of fertilizer along with FYM. Using the basic parameters like NR, Cs, Cf, Cfym per cent, fertilizer adjustment equations were developed. Using the soil test value, fertilizer nutrient value, interaction between soil and fertilizer as independent variable and yield as dependent one, multiple regression equation was developed and coefficient of determination (R2) was calculated. The R2 value (0.8517**) found highly significant. Post harvest soil test values of nitrogen, phosphorus and potassium were predicted based on the values of soil testing, fertilizer nutrients, yield and nutrient uptake. Based on the findings of above mentioned experiment, efficient fertilizer management can be done for urd to obtain targeted yield under a range of soil test value in Mollisol of Uttarakhand. Resource poor farmers could also fetch good profitability by applying fertilizers based on this site specific target yield concept.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-08) Durgude, Shubham Anil; Shri Ram
    Synthesis of nanocomposites, characterization and pot culture studies were conducted for evaluate of mesoporous nano silica (mNs) and reduced graphene oxide (rGO) based nanocomposites of iron (Fe) and zinc (Zn) with rice and wheat crops in zinc deficient alluvial soils belonging to the mollisols of sub-Himalayan region. This greenhouse experiment includes fifteen treatments consisted T1:Absolute control, T2: Control / NPK – Zn, - Fe (no zinc & iron applied), T3:NPK + ZnSO4 ( 20 Kg/ha) + FeSO4 (5 kg/ ha) Basal (Silica/Graphene applied in maximum quantity), T4: NPK + 10 ppm Zn (mNs) + 1 ppm Fe (mNs) Foliar, T5:NPK + 20 ppm Zn (mNs) + 3 ppm Fe (mNs) Foliar, T6: NPK + 30 ppm Zn (mNs) + 5 ppm Fe (mNs) Foliar, T7:NPK + 1 ppm Zn (mNs) + 0.5 ppm Fe (mNs) Soil application, T8:NPK + 2 ppm Zn (mNs) + 1 ppm Fe (mNs) Soil application, T9:NPK + 5 ppm Zn (mNs) + 2 ppm Fe (mNs) Soil application, T10: NPK + 10 ppm Zn (rGO) + 1 ppm Fe (rGO) Foliar, T11:NPK + 20 ppm Zn (rGO) + 3 ppm Fe (GO) Foliar, T12:NPK + 30 ppm Zn (rGO) + 5 ppm Fe (rGO) Foliar, T13:NPK + 1 ppm Zn (rGO) + 0.5 ppm Fe (rGO) Soil application, T14:NPK + 2 ppm Zn (rGO) + 1 ppm Fe (rGO) Soil application and T15:NPK + 5 ppm Zn (rGO) + 2 ppm Fe (GO) soil application in completely randomized block design (CRD) with three replications. Synthesis and characterization of nanocomposites conducted in Nanotechnology unit, College of Basic Science and Humanities, G.B Pant University of Agriculture and Technology, Pantnagar and Indian Institute of Technology, Bombay (Maharashtra) respectively. The characterization revealed successful synthesis of wanted nanocomposites through physico-chemical dimensions with average particles size ranging between 30-80 nm. Seed germination study showed that different exposure levels of nano iron and zinc recorded remarkable increase in seed germination and vigour in rice and wheat. Application of mesoporous nano silica and reduced graphene oxide i.e. @30 ppm Zn + 5 ppm Fe showed better results as compared to all treatments. The column study revealed the slow release properties of prepared nanocomposites as compared to conventional fertilizers (iron sulphate and zinc sulphate). The mesoporous nanosilica based nanocomposites showed comparatively extended (slow) release pattern during 100 consecutive days of application as compared to conventional fertilizers of iron and zinc. In greenhouse studies, growth parameters, yield contributing characteristics, yields and nutrients uptake by rice and wheat crops were significantly higher with iron and zinc application as foliar through mesoporous nanosilica @ 30 ppm zinc and 5 ppm of iron over conventional fertilization. Application of @ 30 ppm zinc and 5 ppm through mesoporous nanosilica as foliar application recorded 53% increase rice yield and 20% increase wheat yield as compared to conventional fertilizer application of ZnSO4 and FeSO4. Significant increase in soil available zinc was observed with application of iron and zinc nanoparticles through mNs @ 5 ppm of zinc and 2 ppm of iron as basal application. Soil microbial population viz. bacteria, fungi and actinomycetes were significantly higher with application of iron and zinc nanoparticles through mNs @ 5 ppm of zinc and 2 ppm of iron as basal application. Dehydrogenase activity got severely reduced with application of nanoparticles of iron and zinc @ 5 ppm of zinc and 2 ppm of iron though reduced graphene oxide (rGO) as basal application. The quality of rice and wheat grains found increased positively in terms of test weight, total protein in rice and gluten in wheat with application of nanoparticles of iron and zinc @ 30 ppm zinc and 5 ppm through mesoporous nano silica (mNs) via foliar mode. The macronutrient viz. NPK use efficiency along with fertilizer use efficiency of iron and zinc nanofertilizers found significantly increased with application of nanoparticles of iron and zinc @ 30 ppm zinc and 5 ppm through mesoporous nano silica (mNs) as foliar when compared with conventional fertilizer application. Thus use of nanomaterials for making nanocomposites of iron and zinc are helpful to increase crop productivity along with grain and soil quality.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-09) Mubashir Sadiq V; Shri Ram
    Synthesis of nanocomposites, characterization and pot culture studies were conducted to evaluate mesoporous nano silica (mNs) and reduced graphene oxide (rGO) based nanocomposites of urea on wheat crop on foot hill alluvial soils. This greenhouse experiment includes thirteen treatments consisted T1-Absolute control, T2-N30 (Urea) P60 K40 , T3-N60 (Urea) P60 K40 ,T4-N90 (Urea) P60 K40 , T5-N120 (Urea) P60 K40 , T6-N30 (Urea-mNs) P60 K40 , T7-N60 (Urea-mNs) P60 K40, T8-N90 (Urea-mNs) P60 K40, T9-N120 (Urea-mNs) P60 K40, T10-N30 (Urea-rGO) P60 K40, T11-N60 (Urea-rGO) P60 K40, T12-N90 (Urea-rGO) P60 K40 and T13-N120 (Urea-rGO) P60 K40 in completely randomized block design (CRD) with three replications. Synthesis and characterization of nanocomposites conducted in Nanotechnology unit, College of Basic Science and Humanities, G.B Pant University of Agriculture and Technology, Pantnagar and Indian Institute of Technology, Bombay (Maharashtra) respectively. The characterization revealed successful synthesis of wanted nanocomposites through physicochemical dimensions with average particles size ranging between 20-50nm. Seed germination study showed that different exposure levels of urea nanocomposites recorded remarkable increase in seed germination. In germination study & green house experiment, application of 120 kg N/ha through ureamNs and 60 kg N/ha through urea-rGO showed maximum crop yields and nutrient uptake by wheat. Growth parameters, yield contributing characters, yields and nutrients uptake of wheat were significantly higher with application of urea-mNs @ 60, 90 and 120 kg N/ha and urea-rGO @ 30 and 60 kg N/ha over conventional fertilization (120 kg N/ha through urea). Application of 120 kg N/ha urea-mNs recorded 17 % and 15 % increase in grain and straw yield of wheat, respectively as compared to conventional fertilizer application of urea. Significant increase in available nitrogen in soil was observed with application of urea-mNs @ 60, 90 and 120 kg N/ha and urea-rGO @ 30 and 60 kg N/ha, similarly soil microbial population, bacteria, fungi and actinomycetes were significantly higher with application of urea-mNs @ 60, 90 and 120 kg N/ha and urea-rGO @ 30 and 60 kg N/ha compared to conventional urea fertilization. In contrast, higher doses of nitrogen @ 90 and 120 kg N/ha applied through urea-rGO resulted in poor seed germination, growth, crop yields, nutrient uptake, available nutrients, microbial population and dehydrogenase activity in soil in comparison to the same doses of nitrogen applied through urea-mNs. Application of urea-mNs and urea-rGO @ 60 kg N/ha recorded statically at par grain and straw yield with 120 kg N/ha applied through urea. Thus use of nanomaterials for making nanocomposites of urea is helpful to increase crop productivity along with grain and soil quality and application of 60 kg N through nanocomposites can replace the urea application for 120 kg N/ha in wheat crops.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-10) Mohammad Nowmaan; Singh, Ajeet Pratap
    A field experiment was conducted during spring season of 2020 with objective to study the effect of different sources of zinc and methods of application on growth, yield, content and uptake of zinc on sweet corn. Sweet corn variety F1 HYBRIB MEETHI grown on silty clay loam soil at N. E. B. Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand. The experiment consisted of 8 treatments with 3 replications in a randomized block design (RBD) viz., T1 (Zn-EDTA 2 FS-0.5%), T2 (ZnSO4 2 FS-0.5%) T3 (Zn-EDTA 1 FS-0.5%), T4 (ZnSO4 1 FS-0.5%), T5 (7.5 kg/ha Zn as ZnSO4), T6 (5.0 kg/ha Zn as ZnSO4), T7 (2.5 kg/ha Zn as ZnSO4) and T8 Control (No Zinc) and recommended dose of N, P and K was applied as basal dose while Zn was applied as per treatments. All the treatments significantly affected growth, yield attributing parameters, content and uptake of zinc in sweet corn. Zn-EDTA (2 FS-0.5%) treatment showed significant result with maximum plant height (125 cm), dry matter accumulation (86.5 g/plant), cob length (18.70 cm), cob girth (15.5 cm), no. of grain rows/cob (16.3), no. of grains /row (39.6), no. of grains/cob (645.4) and individual cob weight (174.5 g), husked cob yield (13968 kg/ha) and dehusked cob yield (10848 kg/ha), green fodder yield (17938 kg/ha), dry yield (husked cob, dehusked cob and green fodder) with 10476 kg/ha, 7594 kg/ha and 7175.20 kg/ha respectively. pH, EC, O.C., available N, available P, available K, days to 50% tasseling and silking, plant population/ha and no. of cobs/ha remained non significant. Zn-EDTA (2 FS-0.5%) treatment showed significant result with Zn (28.42 mg/kg) in corn cob, zinc accumulation in plant (20 mg/kg), zinc uptake by sweet corn plant (147.60 g/ha) and Zn uptake in sweet corn cob (212 g/ha). DTPA extractable soil zinc (1.12 ppm) were found in T5 (7.5kg Zn as ZnSO4/ha). From present study, findings revealed that zinc is needed for the growth of sweet corn in tarai region of Uttarakhand. Zinc applied as foliar application of Zn-EDTA (2 FS-0.5%) at 40 DAS and 65 DAS increased the growth and productivity of sweet corn. It also increased the zinc content in sweet corn. Foliar application of zinc will play a beneficial role for the farmers community by increasing the yield and also ensure their nutritional security.

    Economizing fertilizer nitrogen in wheat (Triticum aestivum L.) by nano formulation application
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-09) Singh, Meenal; Tyagi, A.K.
    An investigation on the effect of foliar application of Nano N on wheat at reduced N levels was carried out at N. E. B. C. R. C. of G.B. Pant University of Agriculture and Technology, Pantnagar in 2019-20. The experiment was designed in RBD with nine treatments, consisting of three levels of N (100, 75, and 50% N of the recommended dose) and foliar spray of Nano N (single and double sprays). Grain yield was found to decrease with decreasing N levels. However, two foliar sprays of Nano N compensated the difference in grain yield in lower level of applied N in 75% treatment. At 50% N level, foliar spray of Nano N failed to maintain the yield level as equal to 100 % N. Single spray was found to increase the grain yield in the treatments supplied with low levels of N, but two sprays found more increment in grain yield. The total N removed by harvested part of wheat significantly decreased with decreasing N levels. Foliar spray of Nano N had no significant effect in treatment with 100 % N level but at 75%N, foliar spray of Nano N significantly increased total N removed by harvested part of wheat. A significant increase was also observed at 50% N level accompanied with two foliar sprays. Soil dehydrogenase, acid phosphatase, alkaline phosphatase activities and microbial biomass carbon decreased with decreasing levels of N. Two foliar sprays of Nano N increased dehydrogenase, acid phosphatase, alkaline phosphatase activities while, it decreased urease activity in soil at both 40 and 75 DAS. Overall, reduction in N levels accompanied with foliar spray of nano nitrogen showed a significant increase in available N, available K, microbial biomass carbon, acid phosphatase, alkaline phosphatase and total N uptake.

    Soil test crop response based site specific integrated nutrient management in mungbean
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-08) Isha; Gautam, Poonam
    Field experiments were carried out as per the design and plan formulated by AICRP on STCR in the D7 block of Norman E. Borlaug Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar (29o N, 79o26’ E, and 243.84 metres above the mean sea level) to work out soil test crop response based site specific integrated nutrient management in mungbean. Prior to the test crop experiment, a soil fertility gradient stabilizing experiment was conducted during rabi 2019-20 by splitting the experimental field into three equal plots. Graded levels of fertilizer nutrients were applied and exhaust crop wheat was grown to create soil fertility gradient artificially. Test crop mungbean (var. Pant Mung 5) was grown during kharif 2020, after dividing each plot into 24 sub-plots (21 treated + 3 control). Response of mungbean to different combinations of varying levels of nitrogen (0, 10, 20 and 30 kg N ha-1), phosphorus (0, 25, 50 and 75 kg P2O5 ha-1), potassium (0, 15, 30 and 45 kg K2O ha-1) and FYM (0, 5, 10 t ha-1) was assessed. Laboratory experiments were also conducted to evaluate seed quality parameters of mungbean using selected combinations of varying doses of fertilizer nutrients with and with out FYM. Before the test crop experiment on mungbean, the soil test value of organic carbon, alkaline KMnO4-N, Olsen's-P, and NH4OAc-K in the entire experimental field varied from 0.702 to 0.995 percent, 112.90 to 225.79 kg N ha-1, 14.58 to 23.80 kg P ha-1, and 112.90 to 276.64 kg K ha-1, respectively. Grain yield of mungbean lied within the range of 4.58 to 14.33 q ha-1. Total N, P and K uptake by mungbean varied between 31.03 to 96.51 kg ha-1, 3.84 to 12.54 kg ha-1 and 17.83 to 49.15 kg ha-1, respectively. Production of one quintal of mungbean grain required 6.72 kg N ha-1, 0.883 kg P ha-1 and 3.52 kg K ha-1, respectively. Soil contributed 28.06, 24.73, and 13.19 percent of N, P and K, respectively. FYM contributed 5.94, 3.18, and 7.21 percent of N, P and K, respectively. Fertilizer contributed 113.22, 15.1, and 39.52 percent of N, P and K, respectively. While, fertilizer in combination with FYM contributed 135.01, 18.85, and 55.84 percent of N, P and K, respectively. Soil test crop response based site specific prescription equations for targeted yield of mungbean were developed with and without FYM and it was found that with specific yield target fertilizer N, P and K requirement decreased with increasing soil test values, however for a specific soil test value, fertilizer N, P and K requirement increased with increasing yield target. Application of FYM reduced fertilizer nutrient requirement for the crop. Maximum response in terms of grain yield and protein yield was observed with the medium dose of nitrogen (20 kg N ha-1), phosphorus (50 kg P2O5 kg ha-1) and potassium (30 kg K2O kg ha-1). Improvement in majority of seed quality parameters of mungbean with varying dose of nutrients (keeping other two nutrients doses constant) was observed with 20 kg N ha-1 with FYM @ 10 t ha-1 ,75 kg P2O5 ha-1 with FYM @ 10 t ha-1 and 30 kg K2O ha-1 with FYM @ 5 t ha-1. Therefore, based on monetary capacity of farmers, findings of the current investigation may be used for fertilizer nutrients prescription for mungbean in similar soil and climatic conditions after its verification at farmer’s field.

    Vegetable pea (Pisum sativum L.) production and soil health influenced under varying irrigation and nutrient management practices in mollisols
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-08) Rajput, Aashu; Raverkar, K.P.
    The investigation was carried during 2020-2021 to study the vegetable pea (Pisum sativum L.) production and soil health influenced under varying irrigation and nutrient management practices in Mollisols. Field experiment was conducted during Rabi season - 2020 at Norman E. Borlaug Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar. The experiment comprised of two irrigation methods (drip and flood) and six different nutrient management combinations, which were replicated three times in Split plot design. Drip irrigation method recorded significantly higher values of symbiotic and physiological traits (nodule number, chlorophyll content, leghemoglobin content and relative water content), growth attributes (plant height, total dry matter accumulation, root dry matter, root shoot ratio and root weight density), yield attributes (pods/plant, individual pod weight, grains/pod and shelling percent), pod yield, nutrient content and uptake, gross and net returns and B:C ratio as compared to flood irrigation. There was no significant difference in soil organic carbon, available N, P and K but dehydrogenase activity was significantly higher under drip irrigation. Irrigation water use efficiency, water and economic water productivity was also higher under drip irrigation (0.087 t/hamm and Rs. 1235/ mm, respectively) compared to flood irrigation. Nodule number, chlorophyll content, leghemoglobin content, total dry matter accumulation, root dry matter, pods per plant, individual pod weight, grain/pod, grain weight per pod, pod length, shelling percent, pod yield and stover yield, N, P, K content and uptake soil pH, EC, OC, available N, P, K, and dehydrogenase activity, gross and net returns and B:C ratio were significantly impacted due to different nutrient management practices. Treatment RDF + FYM @2.5 t/ha + Vermicompost @ 1t/ha recorded higher pod yield, soil organic carbon, economic water productivity and water use efficiency (12.41 Mt/ha, 1.05%, Rs 1075 /mm and 0.066 t/ha-mm, respectively). It can be deduced from the study that integrated nutrient management practice (RDF + FYM @2.5 t/ha + Vermicompost @ 1t/ha) under drip irrigation has great potential to enhanced the growth and yield attributes, pod yield, nutrient content, soil parameters, irrigation water efficiency and confer the economic benefits to the stakeholders. The outcomes of the study also clearly demonstrated the potential of drip irrigation with integrated nutrient management practice (RDF+ FYM @2.5 t/ha + Vermicompost @ 1t/ha) to sustain and improve the soil health under vegetable pea.
