Nutrient use efficiency is a measure of how efficiently plants use the available
mineral nutrients to produce economic produce. Improving nutrient use efficiency
is very much essential under current scenario besides an understanding of the
nutrient dynamics in soil-plant system.”Enhancing nutrient use efficiency:
Concepts, methods, and management interventions” is a comprehensive book
which has a compilation of topics related to enhancement of nutrient use
efficiency of various crops and cropping systems. Although it depends on the
ability to plants to take up the nutrients from the soil, management practices
have a key role to intervene the use efficiency. This book has 27 chapters
written by eminent researchers in the field and addresses multifaceted
approaches to enhance the nutrient use efficiency. Improving nutrient use
efficiency is a prerequisite to reducing production costs in the wake of escalating
cost of agricultural inputs in farming besides minimizing environmental
contamination. Soil physical management is the foremost strategy to enhance
the nutrient use efficiency. Hand held devices are popular among the farmers
for nitrogen management in rice in several parts of the country, besides slow
release nitrogenous fertilizers. Experiences from Long term fertilizer
experiments and soil test crop response correlation are of immense use to
understand the nutrient dynamics in soil and in turn designing practices for
higher use efficiency. Besides describing the concepts and methods of nutrient
use efficiency, management practices for dry land crops and cropping systems,
cereal based cropping systems, rainfed pulses based cropping systems, soybean
based cropping systems, sugarcane based cropping systems, cotton based
cropping systems, tobacoo and oil seed based cropping systems, rapeseedmustard
based cropping systems and spices based cropping systems are also
dealt in this book and would serve as a resource guide for enhancing nutrient
use efficiency in various crops and cropping systems
