Significant Research Achievements: Contributions on nitrogen balance in soil-plant systems have lead to better understanding for (i) enhancing nitrogen use efficiency in rice-wheat cropping system (ii) fertilizer nitrogen related environmental pollution, and (iii) integrated nutrient management. Initiated in early seventies, work on nitrate pollution of groundwater revealed that N fertilizers used as per recommended practices contributed very little to nitrate enrichment of groundwater. These findings along with work on heavy metals supported the cause of achieving sustainability in crop production systems through fertilizer usage. Research on losses of N from soil-plant system has provided basis for enhancing fertilizer N use efficiency and avoiding possible pollution of the environment from fertilizers and helped in formulating more efficient fertilizer management practices for rice and wheat grown in coarse textured soils of north-western India where farmers apply large doses of N fertilizers. Recent work on scheduling fertilizer N to rice and wheat through need based fertilizer applications using leaf colour chart has provided a breakthrough in economizing fertilizer N usage. Contributions in understanding the basic and applied aspects of integrated management of fertilizers, animal manures, green manures and crop residues have provided scientifically sound directions for achieving not only sustainable yields in rice-wheat system but also for maintaining soil fertility for the future generations. Employment history: A. Job title: Assistant Soil Chemist (equivalent to Assistant Professor) in the All India Coordinated Agronomic Research Project of the Indian Council of Agricultural Research at Punjab Agricultural University, Ludhiana. April 1976 to July 1979 Working with a team of soil scientists and agronomists planned and conducted several field experiments on efficient management of fertilizers and manures in crop rotations based on wheat, corn, rice and legumes. Major research activity revolved around studying the leaching of nitrate beyond the root zone of the crops grown in a fixed rotation and how nitrate leaching influenced groundwater pollution. Other important area of research was monitoring of soil quality parameters in plots of long-term field experiments based on different fixed crop rotations and receiving varying amounts of nutrients through fertilizers and organic manures. B. Job title: Assistant Soil Chemist at Punjab Agricultural University, Ludhiana in joint International Fertilizer Development Center (IFDC)/ICAR project - Fate and Efficiency of Experimental Nitrogen Fertilizer Sources in Rice/Wheat. July 1979 to June 1984 Along with Dr JC Katyal worked in close collaboration with IFDC scientists - - Drs PLG Vlek, ET Craswell and RJ Buresh to conduct field and laboratory experiments to study the efficiency and pathways of nitrogen applied as urea, ammonium sulphate, urea supergranules and urea treated with urease and nitrification inhibitors. Field experiments were conducted using 15N -labeled fertilizer materials. It was convincingly proved that supergranule urea was a poor alternative to ordinary urea for rice grown in non-traditional highly percolating soils and thus, as such this source was not introduced in north-western India. It was demonstrated that a breakthrough in increasing the use efficiency on urea can be achieved by imparting slow release characteristics in the granules of urea. In field experiments using 15N labeled fertilizers, it was proved that urea N applied to irrigated wheat grown in coarse textured soils was lost from the soil-plant system by ammonia volatilization rather than leaching and nitrification-denitrification. Confirming that urea N transported to a depth in the soil with irrigation water is protected from loss via ammonia volatilization, it was recommended that urea should be top dressed just before an irrigation event. C. Job title: Visiting Commonwealth Research Scholar at AFRC Institute for Grassland and Animal Production, Hurley, Berkshire / the University of Reading, Reading, UK. January 1985 to January 1986 Worked with late Dr JC Ryden and Professor A.Wild and studied the interaction effects of soil organic matter and moisture on the rate of denitrification under field situations. Relationships between different forms of organic carbon readily available to denitrifiers and potential denitrification losses were also investigated for field moist and air dried soils under grassland and arable cropping.
In the project - Chemical, Physical and Biological Studies in Waterlogged Soils duties include planning and conduct of field and laboratory experiments to find means and ways to efficiently manage nitrogen fertilizers and organic manures including green manures in rice based crop rotations. Dose, time, method of application and source of fertilizer and fate and efficiency of nitrogen applied to rice through bulky organic manures were studied during initial years. Transformations of nitrogen in submerged soils as these are related to fertilizer use efficiency and losses of N applied to wetland rice also constituted an important part of our investigations. Our research has clearly demonstrated that green manuring offers an opportunity to achieve long-term sustainability in crop production systems by reducing external inputs and improving quality and quantity of internal resources. The finding that the yield of rice from N in green manure incorporated in amounts comparable to N supplied by urea equals or surpasses yields from urea should have far reaching positive effects on the adoption of green manures in the years to come; provide farmers can ensure sufficient accumulation of N by green manure crops. On the basis of our work on green manuring in rice-wheat system and integrated use of organic manures and fertilizers, we could win in 1995 the most prestigious Rafi Ahmed Kidwai Memorial Prize of the Indian Council of Agricultural Research. An exhaustive review on green manuring of rice contributed in Advances in Agronomy was the first review ever published in the prestigious journal from the Punjab Agricultural University and sixth from India. A FAO Bulletin on green manuring for soil productivity improvement was also published in 1994. In recent years, emphasis has been on sustainability and productivity issues related to nutrient management in rice-wheat system. Need based fertilizer N management is being worked out using chlorophyll meter. So as to ensure sustainability of the highly productive rice-wheat system, fate and efficiency of fertilizer nitrogen is being studies in conjunction with crop residue management. Field experiments using 15N labeled fertilizer were conducted in close collaboration with Dr. K.F. Bronson, Soil Fertility Specialist at International Rice Research Institute, Philippines to study fertilizer N management in crop residue amended soils under rice-wheat system. In collaboration with Drs. A. Dobermann and KF Bronson, resin capsules are being used to study the nutrient supplying capacity of soils in plots of long-term fertility experiments. During January/February 1998, worked as a consultant in Soils and Water Sciences Division of IRRI to write papers jointly with Drs. Dobermann and Bronson on these aspects. Continuing the collaboration with IRRI, perfected the technology for real time nitrogen management in rice based on Leaf Color Chart in the Punjab, India. Presently, collaborating with Drs. R. Buresh , J.K. Ladha and V. Balasubramanian of IRRI to work on different aspects of sustainability of rice-wheat cropping system. In particular, emphasis is on efficient management of rice residues and nitrogen fertilizers in rice-wheat system. From 2003 onwards associated with PAU/CSIRO/NSW Agriculture ACIAR -funded bilateral research project entitled; 'Permanent raised beds for sustainable rice-wheat and alternative cropping systems in NW India and Australia' to work on simulation modeling aspects of the project. Recently initiated work on UDAID funded project: Accelerating the tillage revolution in the Indo-Ganges basin- Fostering adoption of resource conservation technologies to promote economic growth, resource conservation and food security- Part II: Green seeker sensors for efficient nitrogen management. This project involves calibration of Green Seeker sensor for managing nitrogen fertilizers on rice-wheat cropping systems. G. Job Title: ICAR National Professor at Punjab Agricultural University, Ludhiana. May 2006 to May 2012 To work on the project entitled: Plant-need based nitrogen management in rice and Wheat to work out need based N management options using leaf colour chart and optical sensors. The project aims to work out strategies to enhance fertilizer nitrogen use efficiency in irrigated rice and wheat beyond that achieved through blanket fertilizer recommendations followed over large regions. The underlying philosophy in the project is to devise a combination of anticipatory (preventive) and responsive (during the growing season) decisions to apply fertilizer so as to achieve a congruence between crop uptake of nitrogen (determined by seasonal yield potential) from all sources which include fertilizer, soil, organic manures, residual effects of previously applied fertilizers and manures, crop residues and any atmospheric deposition. For in-season management of fertilizer nitrogen, crop-based approaches ranging from simple tools such as a leaf color chart (LCC) to chlorophyll meters (such as SPAD meter) and optical sensors (such as GreenSeeker hand-held optical sensor) are being used to deal with uncertainties in the prediction of the seasonal crop nitrogen demand as well as nitrogen supply from sources other than fertilizers so as to fine-tune both nitrogen rates and timing of fertilizer nitrogen applications. Salient achievements from the project so far are:
Nature of this job is like a consultant. While working on decision support system for need based fertilizer management in wheat, writing reviews on fertilizer management related issues. Yüklə 250,58 Kb. Dostları ilə paylaş:
