Distributions of different zinc (Zn) forms in seven blocks of rice-wheat growing soils of Jammu region were studied. Understanding the Zn distribution in soil is important for efficient and effective management of the fertilizers recourses and to achieve a higher productivity rate. Sequential extrac[r]

Phosphorus is a major limiting factor for plant growth particularly in the tropics and subtropics areas. It play an important role in many biochemical process viz., energy storage and transfer, cell division, cell enlargement and several other processes in plants. The availability of P to plants is[r]

In this study, the propanil degrading activity of A. baumannii DT isolated from soil (Oanh et al., 2020) was investigated under extreme conditions, in natural water and in soil.

A study was carried out to assess the available nutrient status in soils of Kumbhi block under Lakhimpur (Kheri) district (U.P.). In that context 60 soil samples were collected from the different locations of Kumbhi block. Collected soil samples taken for laboratory analysis and analyzed the physico[r]

which allows rapid absorption of ultraviolet radiation. The photocatalytic activity of TiO2 means that it can be used to produce easy-to-clean surfaces, for air/water purification, deodorization, and sterilization [4-8]. These multiple applications mean that environmental distribution is inevitable.[r]

A field experiment was conducted during Kharif season 2015. The results of the study indicated the application of phosphorus up to 40 kg P2O5 ha-1 recorded significantly higher number of pods per plant, number of seeds per pod and seed and straw yield, nitrogen, phosphorus and potassium uptake in se[r]

In this respect, soil FDA is an important indicator of soil microbial activity and biological health of soil. The aim of this research was to assess the effects of crop residue retention and P fertilization on FDA activity in soil.

Wheat (Triticum aestivum L.) production is often affected due to micronutrient status in soil. Micronutrient deficiency in soil including Boron is very much prominent in India, due to prevalent environmental and soil conditions (viz., wide variation in soil pH, organic matter, salt stress, supply of[r]

A field experiment was conducted at Instructional Farm, Rajasthan College of Agriculture, Udaipur during Kharif 2013 to study the effect of phosphorus rich compost on yield, nutrient uptake and nutrient status in soil after harvest of maize.
