Lora/GSM Based Solar Powered High Efficient Drip Irrigation System for Coffee Farm

The introduction of irrigation reduces the percentage of dried flowers (stars) from 57% to less than 5%, with some percentages practically negligible (Rena / Maestri, 1987 and Thomaziello, 1999). When the productivity results of non-irrigated, irrigated and fertigated coffee were compared, there were increases of 66% and 123% in the irrigated and fertigated zones respectively (Antunes). According to Mantovani (2003), the irrigation of coffee plants is recommended for most coffee-producing regions in Brazil.

The need for irrigation stems not only from the water shortage, but also from the annual mean temperatures. With temperatures below 18o C, irrigation is necessary with an annual water shortage of 150 mm. With temperatures between 18ºC and 24ºC the water shortage is more damaging. In these cases irrigation is recommended with water shortage of 100 mm.

In 2003 it was estimated that 8-10% of the Brazilian coffee plantations — a total of 200,000 Ha — were already being irrigated. This irrigation took place mainly in the states of Espiritu Santo (60-65%), Minas Gerais (20-25%) and Bahía (10-15%).
