Date palm waste compost promotes plant growth and nutrient transporter genes expression in barley (Hordeum vulgare L.)

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