Limited land makes crop choice a question of space before it is a question of price.
Farmers in the Sujalam Sufalam programme tested a structure known locally as machan: a raised frame carrying a climbing crop such as bitter gourd, with turmeric or ginger occupying the ground layer beneath. Rather than giving the plot to one crop, they ran two over the same period.
Seventy farmers used the method across ten acres.
The intended efficiencies were specific: one irrigation serving two layers, shared labour and fertility operations, and separation of the climbing crop from some ground-level pests. Water use was reported at half that of general practice, with claimed improvement in quality and quantity and modelled per-acre income figures.
The defensible change is the adoption of an experimental arrangement at collective scale. Building the structure, choosing compatible crops, timing two cycles and managing shade and water are all farmer judgement, and seventy farmers took on that work and that risk.
Because they were observing across many plots, they could actually compare whether the second crop justified the material and the labour.
DEHAT facilitated the exposure, the demonstration and the technical discussion. It did not grow anything. The farmers built and maintained the systems, dealt with pests and weather, and decided whether the method suited their holdings. Plot size, structure cost, irrigation access, market timing and crop failure would have produced very different results across the ten acres.
Machan appears again in recent individual farm records, which is the point: this is where the shared practice base was formed.
One irrigation serving two crop layers, on land that could not get any bigger.
Collective Experiments Produce Comparable Data
Seventy plots running the same system is a trial. One demonstration plot is a photograph.
