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.

    Response of rhizospheric management on soil health and nutrient use efficiency in wheat (Triticum aestivum L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-02) Arvind Kumar; Singh, Vijay Pal
    A field experiment entitled "Response of rhizospheric management on soil health and nutrient use efficiency in wheat (Triticum aestivum L.)" was conducted during rabi seasons of 2017-2018 and 2018-19 in the D-3 block of Norman E. Borlaug, Crop Research Centre (CRC) of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, District, Udham Singh Nagar (Uttarakhand). The experiment was conducted with 19 treatment combinations and 3 replications in a factorial randomized block design. The treatments were consisted of 3 different placement methods viz: Deep placement, surface application and Band placement, Six nutrient management options viz: 100% RDF (150:60:40 kg/ha NPK), 75% RDF (112.5:45:30 kg/ha NPK), 75% RDF +Vermicompost (2 q/ha), 75% RDF +Vermicompost (2 q/ha) +PSB (10 kg/ha), 75% RDF + Poultry manure (2 q/ha), 75% RDF + Poultry manure (2 q/ha) +PSB (10 kg/ha) with one absolute control. Results suggested that among the different placement methods; Deep placement performed significantly better over rest of the treatments in all the growth, yield attributing characters, yield parameters and soil health parameters. However, it was at par with Band placement. Among the nutrient management treatment, 75% RDF + Vermicompost+ PSB found to be significantly superior to the rest of the nutrient management options. It was also found at par with 100% RDF and 75 % RDF+ Poultry manure+ PSB. Absolute control plot recorded the lowest improvement in growth, yield attributes, yield and soil health. Combined application of Deep placement and 75% RDF+ Vermicompost +PSB or 75% RDF + poultry manure + PSB was found to be the best treatment as they resulted in yield enhancement and improvement in soil health. It also showed economical effectiveness compared to other treatments. Considering widespread low nutrient use efficiency of fertilizers, rhizospheric manipulation with fertilizer placement and nutrient management approach can help in improving both productivity and soil health along with a reduction in the rate of fertilizers. The addition of organic matter into the soil maximized the rhizospheric efficiency and nutrient use efficiency of wheat.

    Effect of different tillage and earthing up practices on performance of maize crop (Zea mays L.) in tarai region of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-10) Nath, Anil; Malik, Naresh
    The present study was carried out during Kharif season of 2017 and 2019 at Norman E. Borlaug Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, district Udham Singh Nagar, Uttarakhand, India representing the Tarai belt of Uttarakhand to study the effect of different tillage methods and earthing up practices on growth, productivity, profitability and nutrient use efficiency of maize crop. The soil of the experimental site was silty clay loam having soil pH 7.19, organic carbon 0.70 % and 233.9, 20.7 and 212.4 kg/ha available N, P2O5 and K2O, respectively. The experiment was laid out in split plot design with 15 treatment combinations. There were 3 tillage methods i.e. conventional tillage, minimum tillage and deep tillage in the main plot and 5 earthing up practices i.e. earthing by pant fertilizer band placement cum earthing machine, earthing by earther, manual earthing, earthing by cultivator and no earthing in the sub plots. The experiment was replicated thrice and maize crop was gown as per recommended package of practices. The different tillage methods had significant effect on growth, yield attributes, yield, N, P and K content and its uptake and economics of maize crop. Significantly higher values of growth attributes of maize were recorded in deep tillage treatment. The deep tillage recorded 9 % higher grain yield as compared to conventional tillage treatment and 20 % higher as compared to minimum tillage. It has also recorded significantly highest value of gross return, net return and B:C ratio as compared to conventional and minimum tillage. The different earthing up practices has also significantly affected the growth, yield attributes, yield, N, P and K content and its uptake and economics of maize crop. The significantly higher values of growth attributes of maize were recorded in treatment earthing by pant fertilizer band placement cum earthing machine. The treatment earthing by pant fertilizer band placement cum earthing machine recorded 9.25 % higher grain yield as compared to earthing by earther, 20.65 % higher than manual earthing, 22 % higher than earthing by cultivator and 36 % higher than no earthing treatment. It has also recorded significantly highest value of gross return, net return and B:C ratio as compared to other earthing up treatments. The nutrient use efficiency of maize was also higher in deep tillage and earthing by pant fertilizer band placement cum earthing machine treatment. It is therefore concluded that maize crop may be grown under deep tillage treatment along with earthing up by pant fertilizer band placement cum earthing machine for higher productivity, profitability and nutrient use efficiency in Tarai region of Uttarakhand and also be replicated in whole Indo Gangetic plains of India.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-09) Arya, Anita; Singh, V.K.
    A field experiment was conducted during the rabi season of 2017-18 and 2018-19 at N. E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) to study the ‘Influence of Altering Plant Rectangularity by Varying Plant Spacing on the Performance of Chickpea Varieties in Late Sown Conditions of Uttarakhand Tarai. The soil of the experimental site was silty clay loam in texture being medium in available nitrogen (315.2 and 321.6 kg/ha), high in available phosphorus (26.6 and 27.8 kg/ha), medium in available potassium (261.2 and 267.3 kg/ha), and high in organic carbon (0.83 and 0.87 %) contents with neutral in reaction (pH 7.30 and 7.46) in 2017-18 and 2018-19, respectively. The experiment consisting of 12 treatments, having three chickpea varieties (PG 186, PG 4 and PG 5) and four rectangularities viz; 0.16, 0.33, 0.50 and 0.66 with a constant row spacing of 30 cm were set out in randomized block design with three replication. Results revealed that different varieties of chickpea were brought significant effect on plant height, number of branches, number of leaflets, plant spread, dry matter accumulation, CGR, number and dry weight of nodules, days taken to 50 per cent flowering and maturity, yield attributes, grain yield, straw yield, biological yield, protein yield, N, P, K uptake by crop and economics of crop growing. Varieties had no significant effect on plant population, mortality percentage, RGR, protein content and N, P, K content in grain and straw. Chickpea variety PG 5 outyielded remaining varieties in terms of all these parameters. Different plant spacings/rectangularity had significant effect on plant population, mortality percentage, plant height, number of branches, plant spread, dry matter accumulation, CGR, number and dry weight of nodules, yield attributes, grain yield, straw yield, biological yield, protein yield, N, P, K uptake by crop and economics were influenced significantly, but had no significant effect on plant number of leaflets, RGR, days taken to 50 per cent flowering and maturity protein content and N, P, K content in grain and straw. The crop sown on 5 cm (0.16) plant spacing/ rectangularity in general, proved to be the best proposition in boosting the yield attributes, and the grain and protein yields of the chickpea in late sown condition. Interaction of chickpea varieties and plant spacing/ rectangularity also had significant effect on dry matter accumulation per plant, pods per plant, 100 grain weight, grain yield per plant, grain, straw and biological yield per hectare, protein yield and total N, P, K uptake by crop. The net return as well as B: C ratio remained higher with sowing of chickpea variety PG 5 at plant spacing/ rectangularity of 5 cm (0.16) in tarai region of Uttarakhand especially for late sown conditions.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-09) Ardeep; Negi, M.S.
    The present investigation was conducted during 2018-19 and 2019-20 at Medicinal Plants Research and Development Centre (MRDC) of G. B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar (Uttarakhand) India, to study the impact of spacing and NPKS management on growth, yield and quality of basil (variety CIM saumya) and subsequent residual effect on mustard crop. The experimental soil was sandy clay loam in texture, neutral in reaction, medium in organic carbon, low in available nitrogen and high in available phosphorus, exchangeable potassium and available sulphur. The experiment was laid out in split plot design (SPD) with three replication having three spacing (40 X 40, 50 X 40 and 60 X 40 cm) as main plot treatment and six NPKS levels (100:60:40:0 (RDF), 100:60:40:20, 100:60:40:40, 120:60:40:0, 120:60:40:20 and 120:60:40:40 kg NPKS ha-1, respectively) as sub plot treatment in basil (Ocimum basilicum) experiment. After the harvest of basil crop mustard crop was grown on residual fertility of basil crop with different varieties (Kranti, PR 20 and NRCHB 101) as main plot treatment and residual fertility of basil crop as sub plot treatments with one recommended dose of fertilizer (RDF) which replaced RDF of basil crop. The spacing of 40 X 40 cm along with 120 kg nitrogen, 60 kg phosphorus, 40 kg potassium and 40 kg sulphur per hectare gave higher growth, herbage yield, essential oil yield and benefit: cost ratio in basil crop compared to other spacings and NPKS levels. Succeeding mustard crop, gave higher number of siliquae per plant, number of seeds per siliqua, length of siliqua, 1000 seed weight, seed yield and stover yield with the application of recommended dose of fertilizers which was on a par with the residual fertility level of 120 kg N+60 kg P2O5+40 kg K2O+40 kg S ha-1 of basil. On the basis of present study, it can be inferred that basil crop performed better when grown at a spacing of 40 X 40 cm along with the application of 120 kg nitrogen, 60 kg phosphorus, 40 kg potassium and 40 kg sulphur per hectare. The yield of mustard variety NRCHB 101 was found higher compared to Kranti and PR 20 when grown on residual fertility of basil crop. The system productivity of basil - mustard cropping system was higher under 40 X 40 cm spacing of basil along with application of 120 kg nitrogen, 60 kg phosphorus, 40 kg potassium and 40 kg sulphur fertilizers per hectare. Thus, for higher profitability of basil - mustard cropping system, growing of basil (Ocimum basilicum) at a spacing of 40 X 40 cm along with the application of 120 kg nitrogen, 60 kg phosphorus, 40 kg potassium and 40 kg sulphur fertilizers per hectare can be recommended for betterutilization of nutrients in Ocimum basilicum crop and harnessing the residual effect on mustard crop.

    Response of kharif maize (Zea mays L.) to differential placement of fertilizer doses and potassium splitting
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-07) Pandey, Deepak; Bhatnagar, Amit
    A field experiment was conducted during the kharif season 2016 and 2017 at the Norman E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar to examine the effect of differential fertilizer placement, potassium splitting and nutrient doses on maize. The experiment consisting of two K split (100% as basal and 50% as basal + 50% at earthing up), eight nutrient doses (75-75-75, 75-75-100,75-100-75, 75-100-100, 100-75-75,100-75-100, 100-100-75 and 100-100-100 per cent of recommended NPK) under differential fertilizer placement depths (50% fertilizers at 10-12 cm and 50% in furrows at 5 cm depth) along with a farmers’ practice treatment (100% recommended NPK dose and furrow application of fertilizers at 5 cm with whole K as basal) was laid out in factorial randomized block design with three replications. The recommended dose of nutrients was 150:60:40 kg N:P2O5:K2O/ha. Planting geometry was 75 cm × 20 cm and crop was grown as per recommended practices. The soil of the experiment site was silty clay loam in texture having medium organic carbon (0.71%), low available nitrogen (234.9 kg/ha) and medium available P (20.7 kg/ha) and K (212.4 kg/ha) contents with neutral pH (7.2). Split application of K had significant impact on growth parameters, yield attributes and yield over its 100% basal application. It resulted in 6.1 and 4.7 per cent increase in grain yield over 100% basal application during 2016 and 2017, respectively. Application of K in splits also fetched higher gross return, net return and B:C ratio than its basal application. Application of 100% NPK being on par with all the nutrient doses in which 100% N was used with either 75 or 100% P and K, produced significantly more growth parameters and yields than the lower doses. Average increment in grain and stover yields under 100% NPK dose was 40.6 and 33.1, respectively over 75% NPK. Economics of cultivation viz. gross return, net return and B:C ratio were also found significantly higher under 100% recommended NPK dose which was at par with 100% N +75% PK, 100% NK+ 75% P and 100% NP+ 75% K. Crop performance in terms of growth, yield attributes and yield was also found significantly higher under differential fertilizer placement with and without K split application than farmers’ practice. Research findings of this study revealed that splitting of potassium in two equal parts i.e. 50% basal and 50% at earthing up in kharif maize is the better option against its whole application in basal in terms of productivity, profitability and nutrient use efficiency under silty clay loam soils of Pantnagar. Differential placement of fertilizers (50% in root zone at 10-12 cm and 50% in seed zone in furrows at 5 cm) can help in saving of 25% recommend dose of P and K.

    Effect of seed invigoration techniques on crop establishment, yield and storability of late sown wheat varieties
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-02) Sharma, Rashmi; Pandey, Sunita T.
    In the present investigation, laboratory and field experiments were conducted in which laboratory experiment was performed at Seed Physiology lab, Department of Agronomy, College of Agriculture and field experiment was carried out at Breeder Seed Production Centre of G.B. Pant University of Agriculture and Technology during Rabi season 2018 and 2019 in a factorial randomized block design with three replications. The seeds of ten late sown wheat varieties (UP 2565, DBW 71, UP 2526, PBW 550, UP 2425, PBW 226, UP 2338, UP 2554, PBW 343, UP 2572) were screened on the basis of their physical, physiological and biochemical seedling vigour parameters. Three varieties i.e. UP 2565, UP 2425 and UP 2338 were categorized high vigour, medium vigour and low vigour respectively. Selected varieties were treated with six seed invigoration techniques i.e. untreated, magnetic field of 100 and 200 mT for 1 hour, hydro-priming for 12 hours, thought energy through BK RYM for four hours and air plasma for 6 minutes. Seeds were stored in polylined cloth bag and seed quality in terms of physiological, biochemical was measured at the interval of 45 days until germination percentage of each treatment declined upto 80%. Same varieties treated with invigoration techniques sown in field to study their growth and development parameters. Under storage, all the three late sown varieties resulted in non-significant increment in seed quality parameters among each other while seeds treated with invigoration techniques performed better than untreated seeds. Plasma treatment and MF 200 mT and hydro-priming improved germination per cent, speed of germination, seedling length, seedling dry weight and vigour of seeds significantly over all the other seed invigoration techniques including control. These particular techniques also improved and maintained cell wall integrity of seed surface and viability of seeds throughout the storage indicated through EC of seed leachate and dehydrogenase activity. Water imbibition, mobilization efficiency and amylase activity enhanced due to plasma and MF 200 mT seed treatment. Seed quality declined due to progression of storage time but both of these techniques resulted in slower drop of seed quality in comparison to untreated seed. In field condition, higher emergence as well as growth parameters was registered in medium vigour variety UP 2425 and plasma, MF 200 mT and hydro-priming techniques. Yield attributes and yield increased significantly under medium vigour variety UP 2425 while in case of seed invigoration techniques, Plasma, MF 200 mT and hydropriming performed well over other techniques including control. Intensity and duration of exposure of seed invigoration techniques vary crop to crop and require proper optimization for seed quality enhancement.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-07) Sirazuddin; Singh, V.Pratap
    Field experiments entitled “Rice Residue Management for Wheat under Different Tillage Systems in Indo-Gangetic Plains (India)” were conducted in D-2 block of Norman E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) during 2017-18 and 2018-19. The objectives of the investigation were to study effect of tillage systems and residue loads on the growth and productivity of wheat, weed species and biomass, properties of soil and energy consumption and economics of different treatments. Field experiments were laid in strip plot design with three tillage systems viz. conventional tillage, reduced tillage and zero tillage systems in vertical strip and three residue loads viz. no residue, 3 and 5 t/ha in horizontal strips and replicated thrice. Rice variety (Narendra Dhan 359) and wheat variety (UP 2628) were used during the study. Tillage systems and residue loads did not influence emergence count and plant height of wheat significantly during both the years. CTW recorded higher plant dry matter and root growth of wheat than ZTW. Tillage systems did not affect number of spikes/m2, length of spike, number of grains per spike, grain weight/spike and 1000-grain weight significantly during both the years. Residue load of 3 t/ha being at par with no residue recorded significantly more number of grains/spike than 5 t/ha during both the years. ZTW recorded comparable grain as well as system grain yield with CTW and RTW. Residue load did not influence the grain and system grain yield significantly during both the years. In the first year, CTW and RTW recorded more population of all major BLWs than that of Phalaris minor. In second year, in tilled plots Phalaris minor dominated BLWs. In ZTW, Coronopus didymus was the most dominating weed species during both the years. The total weed dry matter was the lowest with ZTW in both the years. Tillage system ZTW recorded the higher bulk density and soil moisture than RTW and CTW. Residue load did not influence the bulk density and soil moisture significantly. ZTW recorded 9.11 and 6.19% higher organic carbon stock than CTW and RTW, respectively. ZTW and 5 t/ha residue load recorded the highest dehydrogenase activity in soil. ZTW saved 59.5% fuel against CTW. ZTW consumed 73.77% less mean energy compared to CTW. Combination of ZTW with 3 t/ha residue load recorded higher energy use efficiency, energy productivity and lesser specific energy. ZTW incurred 33.56 and 29.79% lower cost of cultivation than CTW in the first and second year, respectively. Management of rice residue i.e. 3 or 5 t/ha, involved 8.97 and 8.08% more cost of cultivation than no residue in the first and second year, respectively. Tillage practice ZTW and treatment no residue recorded higher system B: C ratio than respective controls.

    Agronomic biofortification of bread wheat (Triticum aestivum L.) with zinc
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-09) Praharaj, Subhashisa; Singh, Rohitashav
    A field experiment entitled “Agronomic biofortification of bread wheat (Triticum aestivum L.) with zinc” was conducted during rabi season of 2017-2018 and 2018-19 in the E-2 block of Norman E. Borlaug, Crop Research Centre (CRC) of G.B Pant University of Agriculture and Technology, Pantnagar, District, Udham Singh Nagar (Uttarakhand). The experiment was conducted with 12 treatments and 3 replications in a randomized block design. The treatments consisted of different zinc fertilization practices which includes the following: T1 (control) , T2 (soil application @ 25 kg ZnSO4.7H2O) , T3 (Nutri priming with 0.3% ZnSO4.7H2O), T4 (T2+T3), T5 (foliar application of 0.5% ZnSO4.7H2O), T6 (foliar application of 0.5% ZnSO4.7H2O + 1% urea), T7 (T2+T5), T8 (T3+T5), T9(T4+T5), T10 (T2+T6), T11 (T3+T6) and T12 (T4+T6). Results suggested that the treatments where zinc was applied through soil application, alone or in combination with other application methods (T2, T4, T7, T9, T10, T12) performed significantly better over rest of the treatments in all the growth, yield attributing characters and yield parameters. However there was no significant difference among these (T2, T4, T7, T9, T10, T12) treatments. Foliar application and nutria-priming treatment was ineffective in bringing significant improvement in growth, yield attributing characters and yield of the crop. Foliar application was very effective in improving grain zinc concentration. Soil application was also effective in improving grain zinc concentration, however they were less effective than foliar application. Combined application of soil and foliar application (T2 + T5 or T2+T6) was found to be the best treatment as they resulted in yield enhancement and grain zinc enrichment. Combined application of soil and foliar application also showed higher benefit cost ratio compared to other treatments. Considering widespread zinc deficiency in soil as well as human diet, agronomic biofortification approach can help in improving both productivity and grain zinc concentration of wheat. This will help in addressing the issue of hunger and malnutrition to a great extent.

    Effect of seed priming and foliar nutrition on yield and seed quality of timely and late sown wheat (Triticum aestivum L.) crop
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-07) Reena; Verma, Omvati
    The present investigation was carried out during rabi season of 2016-17 and 2017-18 at Norman E. Borlaug Crop Research Centre, Govind Ballabh Pant University of Agriculture & Technology, Pantnagar. The experiment was laid out on wheat variety UP-2565 in spilt plot design with three replications. Main plot treatments consisted of two date of sowing viz. timely (Nov 28) and late (Dec 28) and seed priming treatment consisted of seed priming with 2.0% KCl for 12 hours and non primed seed. Sub plot treatment consisted of foliar spray of nutrients viz. 0.5% ZnSO4, 0.5% CaCl2, 0.5% KNO3 and 2.0% urea along with no spray treatment. Foliar sprays were done at maximum tillering and 80% flowering stages. The results revealed that delay in sowing from Nov 28 to Dec 28 resulted significant reduction in grain yield (22.9 and 24.0% during 2016-17 and 2017-18, respectively). Late sown crop experienced significantly higher canopy temperature, lower relative water content and nitrate reductase activity recorded at 15 days after anthesis. Commencement of phenological pahses viz. days to booting, heading, anthesis and physiological maturity occurred earlier in late sown wheat crop as compared to timely sown crop. Nutrient uptake was also significantly reduced in late (Dec 28) sown crop than timely (Nov 28) sown crop. Seed quality in terms of germination, seedling length, seedling dry weight, seedling vigour index, dehydrogenase and alpha amylase activity reduced in produce of late sown wheat crop, whereas, seed protein content was significantly higher in late sown wheat crop. In contrast to this, starch content was higher in timely sown wheat in comparision to late sown wheat. Among seed priming treatments, 2.0% KCl for 12 hours significantly improved field emergence, speed of emergence and plant stand per square metre upto 30 days of sowing. Thereafter, seed priming had no significant effect on crop growth, yield, nutrient uptake and seed quality. Among foliar spray, urea spray @ 2.0% and ZnSO4 @ 0.5% recorded higher grain yield and seed quality in comparision to other foliar treatments. In general foliar application of nutrients particularly urea increased nutrient uptake by the wheat crop. Foliar spray of 2.0% urea in timely (Nov 28) sown crop was found most effective combination to improve quantity and quality of seed. It was also the most remunerative treatment giving the highest net return with B: C ratio. Though, foliar spray of nutrients was less effective in late (Dec 28) than timely (Nov 28) sown wheat, foliar treatment in late sown wheat significantly improved the yield over no spray. Foliar spray of 2.0% urea in late sown wheat recorded maximum grain yield which was at par with spray of 0.5% ZnSO4 in late and no spray in timely sown wheat crop. Thus, foliar spray of urea @ 2.0% and ZnSO4 @ 0.5% at maximum tillering and 80% flowering stage were economically more effective for both the sowing dates and can compensate the yield and quality loss
