Abstract

Application of nitrogen (N) fertilizers to increase crop yield is a worldwide practice, which also has a positive influence on the soil organic carbon (SOC) increase. This study was carried out to investigate the dynamics of SOC and its fractions under different levels of N fertilization in wheat grown inceptisols of Northeast India over a period of 2 years. For the purpose of this study, fertilizer treatments with five N levels (40, 60, 72, 80, and 100 kg N ha−1) were applied in randomized block design. Increased SOC particulate organic carbon (POC), humic acid carbon, and fulvic acid carbon were recorded under application of higher N. Stability of SOC as indicated by E4/E6 ratio and microbial biomass carbon (MBC) was higher on application of 72 kg N ha−1. Among the SOC fractions, POC and MBC respond rapidly to different N fertilization rates. Available N and phosphatase activity increased while pH and urease activity (UA) decreased as a function of applied N fertilizer levels. Nitrogen fertiliza...

Abstract

High temperature has a deleterious effect in productivity of cool season crops like potato. This study was conducted to assess the efficacy of soil management practices to high-temperature tolerance in potato. Two popularly grown potato cultivars of northeast India, Kufri megha and Rangpuria, were sown under optimal and high-temperature conditions with soil application of inorganic nutrients (N, P, K, Ca, Zn), organic amendment, i.e. farm yard manure (FYM), and straw mulch. This integrative soil management practice showed significant positive influence on membrane integrity, chlorophyll content, total soluble sugars and superoxide dismutase activity of potato plant. Higher tuber bulking rate and tuber yield in both optimal and high-temperature situation was recorded under these soil applications. Kufri megha performed better with the application of Ca and Zn along with straw mulch, while Ca with farm yard manure substantially improved restore yield in Rangpuria. Application of CaSO4 and ZnSO4 (20 ...
