Research Details

(i)  Evaluation of non-traditional economic plants under salt stress condition:

Wasteland area is estimated to be about 557.66 lakh ha (16.96 %) in India. Out of that, 6.31 lakh ha area is under saline and sodic condition. Uttar Pradesh is the largest state of the country having 2.13 lakh ha area under saline and sodic soil, which is equal to 33.8 % of the total saline and sodic lands in India (NRSC, 2019). Salt tolerant varieties of some non-traditional crops, which can produce the valuable products under salt stress conditions are experimented for economic utilization of sodic lands. Some non-traditional crops are being evaluated for cultivation in the sodic land with their nutrient management practices. There is a need to study the proposed crops under sodic lands. Some economic plants and their varieties like, Ghritkumari (Aloe vera L.),  Kalmegh (Andrographis paniculata), Ashwagandha (Withania somnifera L.), Satavar (Asparagus racemosus), Tuberose (Polianthes tuberosa L.), Marigold (Tagetis erecta L.),  Gladiolus (Gladiolus communis L.) and Turmeric (Curcuma longa L.) are under evaluation with different levels of sodicity for optimum yield and quality.

Ongoing Project- To identify the potential Aloe species for cultivation in normal and salt affected soils (CSIR-FBR-MLP-0044)

In view of multifarious uses, the demand of the products of the Aloe species is increasing worldwide. Many Aloe sp. are available in the country, but their quality is not standardized for their economic utilization. Nutrients profiling in gel, juice and biochemical compounds of Aloe spp. cultivated under normal and different categories of salt affected soils shall be identified. Potential Aloe species shall be identified for specific quality parameters i.e. vitamins, enzymes, minerals, amino acids etc. Critical limits (Exchangeable Sodium Percentage-ESP) of Aloe species shall be identified for cultivation in salt affected soils.

Ongoing Project- Effect of arsenic on secondary metabolites of ginger (Zingiber officinale) and determination of critical limit in the soil for their cultivation (ICMR-RA)

Medicinal plants cultivated in arsenic contaminated regions may pose health issues in consumers. Ginger (Zingiber officinale Rosc.), a medicinal plant, has been widely used in herbal medicines worldwide. India is the largest producer of ginger and contributes approximately 45% of the world annual ginger production. In West Bengal, Koraput and Kondhamalis districts are the main pocket for ginger production and also a prone area of arsenic contamination. The presence of toxic metals in medicinal plants imposes serious health issues. Thus, it is important to investigate the chemical profile of ginger for protecting human health against arsenic hazard. Low arsenic accumulating ginger variety with high medicinal properties will be screened for safer human consumption.  

(ii)  Soil organic carbon fixation/sequestration:

In recent years, the status of soil organic carbon (SOC) has deteriorated considerably due to long periods of continuous cultivation with chemical fertilizers. The major consequence of the decrease in SOC in soil resulted lower agricultural productivity with direct negative effect on food quality and security. Soil organic carbon  plays a key role in nutrient cycling and help in improving soil structure, nutrient availability and water holding capacity, aeration and workability. We are working for developing modules on the optimum organic carbon levels for optimum yield and quality of the crops and also to identify the suitable tree species for improvement in organic carbon status and quality of the soil under cultivated land use systems in sub-tropical climatic conditions specially for Indo-Gangetic plains of the country with the aspect of carbon sequestration potential to mitigate the problems of climate change.

(iii)  Soil and plant nutrients profiling for optimum yield and quality of the plant:

General recommendations of the nutrient management for crops are not considered suitable for optimum yield and quality of the crop, which is generally practices by the farmers. The Site Specific Nutrient Management (SSNM) is the present need of the development of package of practices for the specific crops in a particular soil condition. Integrated Nutrient Management (INM) is the judicious combination of organic, inorganic and bio-fertilizers. Therefore, we are working on SSNM, INM and organic farming for the non-traditional economic plants.

(iv)  Skill Development/ Outreach Programmes/ Extension Activities:

We organize ‘Skill Development Programme’ on “Soil & Water Testing Lab Analyst” under ‘Agriculture Skill Council of India (ASCI)’ through ‘National Skill Development Council (NSDC)’. Under the extension activities, popularization of soil testing and fertilizer recommendation for the crops, sodic land reclamation and its nutrient management package, selection of the crops/ plants for different sodicity levels, enrichment of the soil carbon pools by various land use practices through training and demonstration.  

Significant achievements

  • Standardized the site specific nutrient management (SSNM) package for Turmeric (Curcuma longa) and package of practices of Kalmegh (Andrographis paniculata Wall. Ex Nees) for cultivation under salt affected soils, organic farming.
  • Successfully evaluated the Coriander (Coriandrum sativum), Ashwagandha (Withania somnifera (Linn.) Dunal) and Kalmegh (Andrographis paniculata Wall. Ex Nees) and determined the critical limit for cultivation in sodic soil.
  • Identified the practices for soil carbon sequestration under cultivated land use systems.
