Yield and Quality of Rice under the Effects of Digestate Application

As a major measure to handle livestock manure, digestate is the by-product during biogas production in anaerobic fermentation. Digestate can be returned cropland as replacement for chemical fertilizer regarding its cost-effectiveness and rich nutrient content. However, optimal rates of substitute have not been validated academically. A field study on nine treatments no fertilizer, at different was conducted investigate effects substituting with digestate. The results revealed that replacing liquid did significantly affect rice growth maximum number seedlings, plant height, tiller numbers, spikelets ear length, grains per spike, grain yields. improvements were found spikelet area second third backward leaves, yields, quality when solid combined. Furthermore, taking inputs, growth, yield, into consideration, applying 150 t ha−1 75 combined 15 suggested venue.
