EFFECT OF DIFFERENT SOURCES AND LEVELS OF POTASSIUM ON GROWTH, YIELD AND CHEMICAL COMPOSITION OF FABA BEAN PLANTS [PDF]

Journal of Soil Sciences and Agricultural Engineering, 2016
A pot experiment was undertaken out door at the farm of Faculty of Agric. El-Mansoura Univ. during the winter season of 2014 to investigate the effect of different sources of potassium fertilization on vegetative growth, chemical composition and yield of

Potassium distribution in soil profiles under no-tillage system [PDF]

Revista Brasileira de Ciência do Solo
Potassium (K) vertical mobility in soils has often been overestimated and used as a rationale for recommending the broadcast application of this nutrient in fertility management programs, especially in soils with low cation exchange capacity (CEC).

Impact of Fractional Calculus on Correlation Coefficient between Available Potassium and Spectrum Data in Ground Hyperspectral and Landsat 8 Image

Mathematics, 2019
As the level of potassium can interfere with the normal circulation process of biosphere materials, the available potassium is an important index to measure the ability of soil to supply potassium to crops.

Effects of steam sterilization on soil abiotic and biotic properties

Soil Organisms, 2020
Experiments under natural conditions are becoming increasingly important to investigate the impacts of global change on biodiversity and ecosystem functioning, but field experiments are not always feasible. Climate or biodiversity chamber experiments can

Spatial variability of soil potassium and its relationship to land use and parent material

Soil and Water Research, 2017
Information on the spatial distribution of plant nutrients is a prerequisite to predict their behaviour and to monitor the fertility in a watershed. This study was conducted to evaluate variations of plant available potassium (PAK) and non-exchangeable ...

Potassium mobilization and plant growth promotion by soil bacteria isolated from different agroclimatic zones of Odisha, India

Acta Agriculturae Slovenica, 2021
Potassium is essential for plant metabolism; improves immunity to stress and increase crop productivity. Soil contains insoluble form of potassium, which is unavailable for plant absorption.

Effects of dual mulching with wheat straw and plastic film under three irrigation regimes on soil nutrients and growth of edible sunflower

Agricultural Water Management, 2023
Mulching is an important practice to reduce soil water loss and improve productivity in agriculture. To investigate the influence of dual mulching with crushed wheat straw padding and plastic film combined with different irrigation amounts on soil ...

Available plant nutrients in soil as influenced by planting methods and herbicidal treatments

Open Agriculture, 2019
Rice (Oryza sativa L.)-wheat (Triticum aestivum L.) is the predominant cropping system of North Indian region. Due to continuous following of rice-wheat cropping system every year, weed infestation particularly in wheat, has emerged a major problem ...
