“…After titration, excess solution was drained off and the roots were then washed repeatedly and dried in an oven at 80°C over night and weighed out in the morning after cooling in desiccators. Cation exchange capacity (CEC) was calculated and expressed as milliequivalents per 100 g (meq 100 g −1 ) of dry plant roots (Chamuah & Dey 1982).…”

A field experiment was carried out in the summer seasons of 2010-2012 at north eastern hilly region of Jharnapani, India, to evaluate the effect of sowing dates, seed rates and integrated nutrition on productivity, profitability and nutrient uptake of summer mungbean. Experimental results revealed that 5th April sown crop recorded significantly higher growth attributes, yield, and economics than 15th April sown crop. This was mainly because of the fact that almost all the yield attributing characters were favourably influenced because of early sowing and, therefore, yield increased. Similarly, 5th April sown crop resulted in higher cation exchange capacity (CEC) of roots, root N content, nitrogenase activity (NA), total uptake of N, P, K and protein yield than the 15th April sown crop. Higher yield and economics were found with seed rates of 35 kg ha −1 , whereas CEC of roots, root N content and NA were higher at 20 kg ha −1 . Application of 50% RDF (recommended dose of fertilizer) + 50% RDN (recommended dose of nitrogen as vermicompost) + PSB (phosphate solubilizing bacteria) produced significantly higher growth attributes, yield and economics of mungbean.

The low availability of phosphate is due to fixation by Al and Fe at acid pH, making it unavailable to plants. These problems can be overcome through the utilization of soil microbes and Arbuscular Mycorrhizal Fungi (AMF) that can associate with corn plants. This study aims to determine the effect of indigenous microbes and arbuscular mycorrhiza on phosphate nutrients. The experiment used a nested design with three factors. The first factor is land use, consisting of inceptisol moorland soil and inceptisol forest soil. The second factor is soil sterilization consisting of sterile and non-sterile. The third factor is mycorrhiza, consisting of non mycorrhiza and mycorrhiza inoculation. The results showed that land use had a significant effect on total P, potential P, Al oxide, and Fe oxide. However, it did not significantly affect available P, P uptake, and root CEC. Soil sterilization and mycorrhiza inoculation significantly affected available P, total P, potential P, P uptake, Al oxide, Fe oxide, and root CEC. The treatment interaction significantly affected all parameters, except P uptake and root CEC. However, there was a negative relationship between Al and Fe oxide content on available P and P uptake. The best phosphorus response was non sterile forest inceptisol soil with mycorrhizal inoculation.

“…Rice roots were sampled at 50 days after transplanting (DAT) to determine root CEC using ammonium acetate as an extractant [30]. About 1 gram of fresh root sample was dipped twice into standard 1 N ammonium acetate solution for 150 seconds with 100 ml of each solution.…”

The presence of excessive salt around root system disrupts water and nutrient uptake by root, causes inhibition of plant growth resulting in low plant yield. Arbuscular mycorrhizal (AM) symbiosis known for its mutualism towards plant by enhancing plant root growth. This study examined how AM symbiosis improved root growth and yield of rice plant under different salinity levels. The experiment was conducted in the screenhouse of Faculty of Agriculture, Universitas Gadjah Mada which arranged in a Randomized Complete Block Design (RCBD) with two factors. The first factor was rice plant that applied with and without arbuscular mycorrhizal inoculum. The second factor was four salinity levels at 0 dS m-1 (non-saline), 2.5 dS m-1, 5 dS m-1, 7.5 dS m-1. The results showed that the increase of salinity level treatment was followed by increasing of root Na content, resulting in decreasing of root growth as well as plant yield. Higher colonization rate in mycorrhizal plant than non-mycorrhizal plant caused two-fold increase in root cation exchange capacity (CEC). Under salinity, roots of mycorrhizal plant became longer and thicker, also root fresh weight did not decrease compared to non-mycorrhizal plant. By having higher root CEC and more extensive root, mycorrhizal plant was able to alleviate yield loss under 7.5 dS m-1 salinity stress.
