Abstract/Description: | Indigenous rainguage (Rolu) (IR) is one of the Indigenous technical knowledge, which helped the farmers in quantifying rainfall approximately for farm operations. It is a mortar made of granite with a hole of 22.5 cm f and 2000 ml capacity. Depending upon the depth of water received in the hole of IR, the amount of rainfall received can be known and farm operations can be carried out. To standardize IR, validation of IR was done in three on-farm conditions and two research farms of CR1DA, Rangareddy district. Andhra Pradesh for three years and a correction factor was derived as 0.48. Some refinements were also carried out during this process like making a barrier surrounding the hole and creating an outward slope on the periphery of IR to avoid overflow, splash and human interferences. It is concluded that when the IR is >l/2 to full, all the farmers (100%) are proceeding to sow crops like sorghum +pigeonpea and castor for 2–7 days and 3–6 days respectively. If the rain is filled to 1/4th to 1/2 of the volume of the hole, they are carrying the operation of sowing for 1–2 days. Intercultural operations like weeding, topdressing were earned out for 2–4 days when IR is filled to >l/2 to 3/4th depth and about 6–8 days when IR is >3/4th to full depth. |
