“…2 In the RD farming method, in general, rice paddies supply food for ducks and provide fertile grounds for rice cultivation. 3 Raising ducks in rice paddies helps to reduce insect outbreak risks, while weeds and planting density are controlled. 4 In addition, the use of artificial fertilizers and pesticides can be reduced, and soil nutrient levels can be increased by duck excrement.…”

BackgroundTo maintain rice production and increase revenue, rice‐duck (RD) farming is a contemporary ecological cycle technology that has been widely used in Asia. However, due to the clustering activity of duck flocks, the consequences of long‐term rice‐duck farming on rice growth at different scales are still unknown. Here, we studied rice‐duck farming at several different treatments (CK: conventional rice farming, RD1: 667 m2, RD2: 2000 m2, and RD3: 3333 m2).ResultsThe results demonstrated that the maximum tillers, effective spikes, dry matter accumulation and lodging index of rice under rice‐duck farming were significantly decreased by 17.9%, 9.8%, 14.8%, and 17.8%, respectively, which ultimately caused a significant decrease in yield of 10.6%. However, rice‐duck farming significantly increased root oxidation activity and the earbearing tiller rate of rice by 25.5% and 11.1%, respectively, and improved yield stability. For different scales of rice‐duck farming, the lodging resistance index of RD1 was significantly lower than that of RD2 and RD3 by 10.0% and 15.2%, respectively, whereas the root oxidation activity and dry matter accumulation of RD2 were significantly higher than those of RD1 and RD3 by 11.1%, 4.7%, 8.6% and 5.1%, respectively. For rice yield, there was no significant difference among the different scales.ConclusionThis long‐term experiment helped elucidate the complicated effects of rice‐duck farming at different scales on the growth and yield of rice. It is also critical to consider the economic advantages of different scales of rice‐duck farming to assess the impact of this system more thoroughly.This article is protected by copyright.

Retrospection of Outbreaks of Spodoptera mauritia Boisduval in NER India: The Solution Lies in Ecological Engineering, Not in Insecticides

Rice cultivation in North East India is organic by tradition; however, the recent outbreaks of the rice-swarming caterpillar, Spodoptera mauritia Boisduval, have compelled rice-farmers to use synthetic insecticides. The outbreak in 2016 affected more than 56,768 ha of winter rice in 28 districts of Assam. About 25,545–42,576 L insecticide was applied in the state to combat the outbreak. This is one of the highest insecticide loads ever to be added to the rice ecosystem of Assam. Such a load, if added repeatedly with the reoccurrence of outbreaks, may affect the innate resilience of the rice ecosystem in the long run. In this paper, the outbreak of RSC has been analysed from an ecological perspective in order to replace the existing policy of exclusive dependence on insecticide. The review will help the researchers, extension workers and policy makers of the rice producing countries, more specifically in Asian countries, which together account for more than 91% of the world’s rice production.
