COMPARATIVE ANALYSIS OF CITRIC ACID PRODUCTION BY Aspergillus niger USING DIFFERENT MEDIA | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

To investigate high yield citric acid producers other than citrus fruits, Aspergillus niger was used for submerged citric acid synthesis. For a comparative investigation of higher yielding substrates, rice and potato extracts were used as substrates. The changes in citric acid output were tracked using different amounts of Sucrose, Glucose, and Nitrogen supplementation. The concentration of citric acid generated was determined by titrating citric acid extracted from various mediums. The objective of the comparison study was to determine the ideal requirements for a greater yield of citric acid production. This research could help with large-scale industrial manufacturing of citric acid, which is one of the most widely used organic acids.

Phytophthora infestans (Mont.) de Bary (Peronosporales: Pythiaceae): A REVIEW OF LIFE HISTORY, EVOLUTIONARY STATUS OF PATHOGEN, HOST RANGE, MATING TYPES, SYMPTOMOLOGY, DISEASE CYCLE, MEANS OF DISPERSAL, EXTENT OF LOSSES, AND MANAGEMENT | Journal of Global Agriculture and Ecology

Solanum tuberosum L. (Solanales: Solanaceae) is one of the world’s most frequently grown food crops, producing roughly twice as many calories per hectare as rice and wheat. It is regarded as the most significant food crop, with high nutritional value. There are several diseases that impact potato crops, but late blight caused by Phytophthora infestans (Mont.) de Bary is the most common. This disease has the potential to utterly devastate a potato crop in a short period of time. As a result, it was necessary to review the various aspects of P. infestans (Mont.) de Bary, including its life history, evolutionary status, symptomology, disease cycle, means of dispersal, extent of losses, and disease management using conventional/commercial fungicides and plant extracts/non-conventional methods.

REACTION OF POTATO VARIETIES/LINES AGAINST (PVY) UNDER NATURAL FILED CONDITIONS AND CONFIRMATION OF THE FIELD RESULTS THROUGH ELISA | Journal of Global Agriculture and Ecology

A reduction in potato area and productivity has been documented as a result of a variety of variables, the most important and harmful of which is PVY. This illness can cause yield losses of up to 80%. Because no chemical exists to combat viral plant diseases, the only way to deal with the problem is to generate resistant types through conventional or molecular breeding techniques. For the availability of resistance sources, we investigated locally produced potato lines in natural field circumstances. Twenty-seven lines/varieties were cultivated in natural field settings and tested for the presence or absence of resistance to PVY using an ELISA kit. No line/variety was found to be immune in a field study, which was validated by an ELISA test. PVY resistance was found in four lines/varieties: Lady Rosetta, Crusier, FD 69-1, and FD 35-36, while two lines/varieties were moderately resistant and 21 lines/varieties were severely vulnerable to PVY.

EFFECT OF DIFFERENT WEED MANAGEMENT PRACTICES ON YIELD OF POTATO IN CHATTOGRAM HILL DISTRICTS OF BANGLADESH | Asian Journal of Plant and Soil Sciences

A field experiment using potato was conducted in 2017-2018 at farmer’s fields in the three hill districts of Chattogram, Bangladesh, to examine the influence of different weed management strategies on potato yield. T3 (Hand weeding + Mulching= Two hand weeding was done in 30 DAT and 90 DAT and straw mulching was done in 30 DAT and continued up to harvesting) had the highest weed control efficiency and marketable tuber yield, followed by T4 (Herbicide =Apply paraquat in 30 DAT and 60 DAT @ 851 g a.i. ha-1), T2 (Mulching= Straw mulch were done in 30 DAT and continued up to T6 unweeded control treatment yielded the lowest yield. As a result of the experiment’s findings, we now have a fantastic potential to use hand weeding and mulching in combination to deal with the labour shortage and reduce cultivation costs in Chattogram’s hill areas..
