“…AM fungi influence microbial population and activity and consequently nutrient dynamics in the soil through the release of organic compounds [6,7]. AM fungi may directly or indirectly contribute to soil C and N dynamics and it could be source of different soil enzymes required for biochemical reactions [8,9]. These reports indicating that soil enzymatic activities, such as dehydrogenases and phosphatases are increased by AM fungal inoculation [10].…”

The present study assessed the effect of Arbuscular mycorrhizal fungi on nutrient uptake and soil enzyme activity of tobacco rhizosphere under parasitic weed stress condition. The experiment was carried out in Orobanche infested soils of Belagavi district during 2018-19. During the investigation different inoculation methods of Arbuscular mycorrhizal fungi were screened for their ability to improve the nutrient uptake and soil enzyme activity i.e. (pre inoculation of nursery seedlings; direct soil application and the combination of both). The present experimental results revealed that soil enzyme activities like dehydrogenase, phosphates and urease activity was highest in treatments received planting of pre colonized tobacco seedling with STD AMF along with soil application at the time of planting and second highest was recorded in the treatment received pre colonized UASDAMFT plus soil application. Furthermore nutrient uptake like N, P, K and micronutrients were found to be the highest in the plots received mycorrhization compare to the rhizosphere of non mycorrhized plants. In mycorrhizosphere the activity of mycorrhizal fungi and other beneficial microorganisms could be a source for different soil enzyme needed for biochemical reaction in the plant rhizosphere.

“…Hence difficult to suppress these parasitic weeds under field conditions. Thus an integrated approach is needed for the management of these parasitic weeds like cultural practices, crop rotation, host plant resistance, chemical and biological treatments [2,3,4,5]. Hence, there is a need to develop a comprehensive and ecofriendly management system for their control.…”

An investigation was carried out to evaluate the methods of application of AMF cultures in the management of Orobanche viz., planting of pre colonized tobacco seedling; soil application and the combination of both. The experiment was carried out in Orobanche infested soils of tobacco growing areas of Belagavi district. The results of the present investigations have revealed that the treatment received STD AMF had reduced the emergence of Orobanche (1.33 plot-1) compared to UASDAMFT (1.67 plot-1) and UASDAMFS (2.89 plot-1). The results with respect to different methods of applications of AMF on Orobanche numbers revealed that planting of pre colonized tobacco seedling plus soil application at the time of planting suppressed the Orobanche emergence (0.00 plot-1) compared to planting of pre colonized seedlings (1.67 plot-1) and direct soil application of AMF cultures at the time of planting (4.22 plot-1).The results pertaining to the interactive effect between mycorrhizal cultures in conjunction with the methods of application of AMF cultures significantly reduced the population of Orobanche with the treatment received planting of pre colonized seedling along with soil application of UASDAMFT, UASDAMFS and STD AMF recorded zero emergences of Orobanche at 60 DAP. However, the highest numbers of weeds were recorded in uninoculated control (68.67plot-1). Furthermore, mycorrhizal parameters like spore count and percent of root colonization were found to be the highest in the plots received mycorrhization in the form of pre-colonization and soil application with STD AMF at the time of transplanting in the main field compared to uninoculated control.
