Abstract

Organic fertilizers have been used in agriculture to improve soil fertility, promote plant growth and protection which improves crop productivity. A field experiment was conducted in order to study the effect of organic fertilizers (compost and its water extract) on growth and yield of organic barley production. The results achieved showed that either compost (T3) or dual application with compost water extract (T4) as biofertilizers increased most yield parameters including straw yield as well as biological yield, number of grains per spike and grain income. With respect to photosynthesizing pigments, the application of T3 and T4 increased chlorophyll a, chlorophyll b, total chlorophyll as well as carotenoid content compared to control plants (T1). Nutrient uptake of barley plant, but not grain, also increased under T3 and T4 treatment. This suggests a promoting effect of compost on barley plant growth, development and productivity, as well as nutrient content. Overall findings indicate the effectiveness of compost and its extract application in significantly improving yield performances of barley crop under a field organic farming system. This indicates that compost and its extract could be used as organic fertilizer for barley cultivation under organic farming condition. Real-time PCR analysis showed differential expression of 24 candidate genes such as NRT1, NRT2, AMT and PHT involved in N and P metabolism in barley leaves and roots. This suggests that these genes may play various functions and control the uptake, transport, reduction, assimilation and translocation of nitrate, ammonium and phosphorus in barley vegetative organs.
