Rice polyculture is the cultivation of rice and another crop simultaneously on the same land. The practice exploits the mutual benefit between rice and organisms such as fish and ducks: the rice supports pests which serve as food for the fish and ducks, while the animals' excrement serves as fertilizer for the rice.
While rice is growing: Ducks eat pests (e.g. brown planthoppers) in the crop; they stir water, limiting weeds, and manure the rice. Surface must be even; water depth must suit ducks; young ducks best as they don't nibble rice leaf tips.

The System of Rice Intensification (SRI) is a farming methodology that aims to increase the yield of rice while using fewer resources and reducing environmental impacts. The method was developed by a French Jesuit Father Henri de Laulanié in Madagascar [ 1 ] and built upon decades of agricultural experimentation.
Rice-fish systems were traditionally low maintenance, growing additional animal protein alongside the staple food, rice. [3] The space used for fish-rice systems in China grew from 441,027 hectares (1,089,800 acres ) to 853,150 hectares (2,108,200 acres) and the production increased dramatically, going from 36,330 tonnes to 206,915 tonnes ...
What it took to build rice fields from the swamps over such a vast area, Wiggers said, isn’t fully appreciated. And the size of the successful rice growing operations also reveal the farming and ...
Direct seeded rice (DSR) [2] [3] is a practice of sowing paddy which involves planting rice seeds directly into the field, instead of the traditional method of growing seedlings in nurseries and then transplanting them into the fields. This method significantly reduces the demand for labor, one of the major costs associated with rice farming.
