The study has been conducted in the plains and undulating terrains of Uttarakhand to evaluate the performance of geospatial tools in identification and delineation of potential sites for Bamboo plantations. ENVI-4.8 image processing software was used over LANDSAT-ETM+/TM imageries to generate land use/land cover map. The various climatic and soil t...

The present study has been conducted to identify suitable potential areas for willow plantations under wastelands of Haryana. Weightage of climate and soil parameters have been assigned as per the optimal growth requirements of different tree species in Haryana. Station wise weather data have been collected from various sources to generate climatic...

ICAR-Indian Institute of Wheat and Barley Research annual report presents the salient achievements for the year 2017-18

Full Paper Link: https://www.sciencedirect.com/science/article/pii/S1470160X18301389 India’s geography, monsoon dependency and weather anomalies place wheat production prospects and sustainability at crossroads across agro-ecologies owing to its vulnerability. An attempt has been made to track the vulnerability in wheat producing regions for clima...

In the present study, combination of NDVI and decadal weather variables was used to develop spectral-meteorological models for district-level wheat yield prediction for US Nagar district of Uttarakhand during 2005-06 to 2014-15. Cloud free crop season's images of LANDSAT-TM/ETM+/OLI satellite for a period of ten years (2006-2015) of path 145 and ro...

Agriculture is a primary occupation and has been more intensified to feed the growing population, which has resulted in adverse effects on different production components, especially soil health. Soil is the substratum required to support the plants grow and ultimately human life; for sustainable agriculture it is necessary to have a holistic soil...

The 2017: 11 (1) edition of the Newsletter presents the salient research findings on various aspects of wheat & barley crops, awards and other accomplishments from ICAR-IIWBR.

Preponderantly, wheat and barley production is a biological and societal activity which is guided by several factors including policies and weather aberrations across states. Hence, there are a lot of risks and uncertainties associated with farming leading to spatial vulnerability particularly for an agrarian economy like India which depends on mon...

Climate change is a serious concern affecting the wheat production prospects. In the recent past, yield sensitivity to climatic variables has been noticed and it has to be addressed in the perspective of climate smart farming. The present study has tracked the perception of farmers on climate change and sensitivity to crop yield. Perception of the...
