Figure 4From: Supporting food security in the 21st century through resource-conserving increases in agricultural productionResistance to biotic and abiotic stresses based on alternative crop management: two adjacent rice paddy fields in Crawuk village, Ngawi district, East Java, Indonesia, after they were both hit by a brown planthopper (BPH) attack and then by a tropical storm in June 2011. Paddy field on left, planted with an improved rice variety (Ciherang) and using inorganic fertilizer and agrochemical protection, gave almost no yield because of BPH burn and lodging. From the field on the right, 1,000 m2 in area, planted with an aromatic unimproved variety (Sinantur) and having organic SRI management, 800 kg was harvested, a yield of 8 tons/ha.
