Integrated and Site-Specific Fertilizer Application Role in Rice-Wheat Cropping System

Abstract

Introduction Rice (Oryza sativa L.)-wheat (Triticum aestivum L.) is one of the world's largest agricultural production systems. Intensive farming techniques, unbalanced application of chemical fertilizers without proper review of soil nutrient status, poor soil management and high-yielding crop varieties have resulted in a substantial decrease in soil organic matter (SOM) and crop productivity over the past decades. [1, 2]. A useful strategy to feed the rapidly growing population is to increase the unit area production by using existing agricultural area and resources [3]. This can be accomplished by growing improved crop varieties [4], site specific way of fertilizer application [5], integrated

“…However, the use of inhomogeneous mixtures with a complex composition of mineral fertilizers or pyrethroids can cause irreparable harm not only to various varieties of cultivated plants but also affect the state of the ecosystem. For example, the quality of the soil, its microflora, harm the animal world and human health [4,5]. Note that the toxic properties of some mixed components for special purposes [6] impose certain restrictions on experimental studies of the conditions for their effective mixing.…”
