Study of meteorological drought and its impact on rainfed paddy productivity in Gunungkidul Regency

Gunungkidul Regency is known as an area that often experiences drought. On the other hand, Gunungkidul Regency is also the regency with the highest amount of rice production in the Special Region of Yogyakarta Province. Rainfed paddy farming is the most widely developed type of paddy in Gunungkidul...
