Moong, also known as green gram or maash, is a round, olive green legume that's high in protein, calcium, potassium, and iron. It's a warm-season crop that grows quickly in tropical and subtropical conditions, and can be sown in summer and autumn. Moong can grow in a variety of soils, but prefers well-drained loams or sandy loams with a pH of 5 to 8. It's also somewhat tolerant of saline soils
