Tomato cultivation in Northeast India faces a formidable challenge from late blight, caused by Phytophthora infestans (Mont.) de Bary. Field experiments conducted during 2021–2023 have shed light on effective management strategies. Among these, copper oxychloride at 0.25% emerged as the most effective treatment, closely followed by copper hydroxide...
During the experimental trial, it was observed for the first time that the king chilli and tomato were infested by root knot nematode. Showing the general
symptom of patchiness, yellowing of leaves and wilting of infested plants as well as the typical symptom of root knots/galls formation with the presence
of egg masses attached to it. Morphologi...
Eight tomato germplasms were evaluated against late blight disease under natural epiphytotic conditions.

weaving different items. This study was conducted in Hayuliang, Metengliang
and Goiliang Circle of Anjaw district,...
Since ancient time, different methods of storage for locally produced goods have been practised using traditional methods in India. Although, difference in techniques of storage are result of difference in knowledge of cultures, their attentiveness to geographic and climatic conditions. "Shezing" is the local storage method for Chow Chow in Anjaw-d...
