Redgram, blackgram, greengram and bengalgram are pulse crops found in AP district crop lists. Their names can appear in English or local usage; “gram” alone is ambiguous, so read the qualifier. Pulses supply protein and can fit rainfed or post-paddy systems depending on the crop and local conditions. Some pulse crops are legumes that contribute to soil nitrogen processes, but a field's fertiliser recommendation still requires testing and agronomic advice.

Guntur's district page lists multiple pulses, while Ananthapuramu includes redgram. Prakasam's planning page identifies crop-estimation surveys for redgram, blackgram, greengram and bengalgram. These are official evidence that the crops matter to statistical reporting. An exam may ask which item is an oilseed rather than a pulse: groundnut is usually classified as an oilseed in crop statistics despite its legume botany. The classification context matters.

Worked example: Pulses can fit rotations or mixed systems and can affect soil nutrient dynamics. An exam that asks whether a pulse is a cereal should be answered by crop class, not its local market price. The exact area under a pulse changes by season and rainfall. If a crop-estimate table lists 'total pulses', check whether it includes several species before comparing it to one named crop.

Active recall: Classify redgram, blackgram and groundnut as used in AP crop statistics.
