Article
Full-text available
Pigeonpea (Cajanus cajan (L.) Millsp.) is grown globally for its protein-rich seed. However, low availability of soil zinc (Zn) adversely affects the seed yield of pigeonpea. The present study was therefore conducted to assess the Zn efficiency of pigeonpea genotypes based on seed yield and seed Zn uptake efficiency. Field experiments were conducte...
Article
Low zinc (Zn) availability in various agricultural soils including Vertisols adversely affects wheat production. The variations among the wheat genotypes to produce high grain yield and Zn uptake under low Zn supply were investigated to find out the Zn-efficient genotypes. Twenty-five different wheat genotypes were evaluated in the field with two l...

Deficiency of zinc (Zn) in soils and crops of the world is established fact. There is need for application of Zn application and growing Zn-efficient crop genotypes to tide over the situation. However, information pertaining to application of Zn to Zn-efficient and Zn-inefficient crop genotypes grown in field condition on plant enzyme (wherein Zn i...
Book
This is the training manual of SAARC Regional Training Program ‘Mass breeding and culture techniques of catfishes’ conducted at ICAR- Central Institute of Freshwater Aquaculture (ICAR-CIFA), Bhubaneswar, India during 16-21 July 2018. The training was jointly organized by the SAARC Agriculture Centre (SAC), Dhaka, Bangladesh, ICAR-Central Institute...

Emerging micronutrient deficiencies in different soils of the world is a threat for sustainability of agriculture. As distribution of micronutrients in soil varies spatially, site‐specific management of micronutrients by delineating regional zones (RZs) is an effective strategy for precision agriculture. The current investigation was performed to d...

Agricultural land degradation due to nutrient deficiencies is a threat to agricultural sustainability. As nutrients availability is influenced by soil heterogeneity, climatic conditions and anthropogenic activities; hence, delineation of nutrient management zones (MZs) based on spatial variability could be an effective management option at regional...

Full-text available
Zinc (Zn) and iron (Fe) are essential for plants as well as humans and animals who consume plant produce. Zinc and Fe pose critical nutritional issues as their deficiencies cause severe impairment of animal/ human health. Most of the nutrients required for animal/ human come from plants through soil and low concentration of Zn/ Fe in plant produce...
Article
Full-text available
Content of micronutrients and their ability to supply to crop vary widely depending upon soil types, nature of crops grown, ecology and agro climatic variability. Total levels of micronutrients are rarely indicative of plant availability, hence, rational management of micronutrient fertility and toxicity requires an understanding of how plant-avail...
Article
Full-text available
Soil microbial population, dehydrogenase activity and chemical properties of soil under different doses of farmyard manure (FYM), leaf compost and vericopmpost were examined at the research farm of the Indian Agriculture Research Institute (IARI), New Delhi, India during 2008-09 and 2009-10. Results indicated the higher value of microbial populatio...

Full-text available
Micronutrient deficiency is major constraints in crop production as well as crop quality. The deficiency of micronutrients in soils leads to lower micronutrient content in edible plant parts and thereby causing a health problem in animal and human beings. Level of micronutrients in soils is determined by geologic substrate and subsequent geochemica...
