ABMA Industries, based in Dalkhola, West Bengal, India, seems to be involved in the trade and processing of agricultural products like maize, rice, and makhana. Here's a breakdown of the items they deal in:

1. Maize: Maize (also known as corn) is a versatile cereal crop that is widely grown across India. It is used in various food products, animal feed, and industrial applications. Maize is a staple in many households, especially in rural areas, and is also used to make products like corn flour and cornmeal.
   
   

2. Rice: Rice is one of the most important food crops globally and is a staple diet for millions of people in India. West Bengal is one of the largest rice-producing states in India, so ABMA Industries could either be involved in milling, processing, or trading rice for consumption or export.
   
   

3. Makhana (Fox Nut): Makhana, also known as fox nut, is a popular snack in India, especially in the northern and eastern parts. It’s also used in traditional dishes like makhana kheer and has health benefits, as it's rich in protein, fiber, and antioxidants.
   
   

If ABMA Industries is involved in the processing and trading of these products, they could be a key player in the local and regional agricultural supply chain, potentially serving both domestic and international markets.
