SYSTEM OF PLANT INTENSIFICATION (SPI) CULTIVATION

SPI is one of the improved methods of cultivating ragi and dryland paddy by maintaining minimum distance between the plants. Planting two seeds per hill at adistance of every feet can be called SPI method of cultivation. The main purpose of this SPI method is to reduce the quantity of seeds used for cultivation, to increase the number of tillers, simplify weeding and obtain a higher grain and fodder yield.

High yield of the crop is assured. Drought tolerance can be achieved by reducing population. It is very easy for weeding. Tender Ragi and paddy receive very good sunlight because of wider space between the seedlings making the plants very strong and healthy. Only one to two kilos of seeds are required to cultivate one acre of land. In general we can say that the farmer has many advantages in the SPI method but it takes some extra effort for cultivation.
