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

Proteomic Analysis of Barley (Hordeum vulgare L.) Leaves in Response to Date Palm Waste Compost Application

“…This could be due to the compost richness in easily assimilated available substances, providing carbon, nitrogen, phosphorus, and potassium to soil [ 13 ]. The positive effect of compost amendment on barley growth has been also demonstrated by other studies [ 9 , 14 ] who reported that compost application increased plant height and dry biomass. Furthermore, barley plants which received 30 t ha −1 of date palm waste compost showed higher photosynthetic pigment (Chla, Chlb, Chlt and carotenoids) concentrations when compared to the non-amended barley plants.…”

“…Several studies reveal that application of date palm waste compost could be used as an efficient organic fertilizer for growth, yield and quality of crop plants such as barley [ 9 ], alfalfa [ 11 ] and tomato [ 12 ]. Compared with untreated soil, the date palm waste compost application significantly improved vegetative activity of the barley plant which is evaluated as shoot length and shoot dry weight.…”

“…Experimental treatments were organised in random blocks design (each experimental plot size was 3 m length × 2 m width) with 3 repetitions per treatment as the following: (T1) unamended soil (control) and (T2) soil amended with 30 t ha −1 of date palm waste compost. Based in our previously finding, date palm compost at moderate dose (30 t ha −1 ) showed highly beneficial for barley plant growth and yield [ 9 ]. Physical, chemical and biological properties of the date palm leaf compost used in this study are presented in Table 5 .…”

“…Recently, application of date palm waste compost has positively affected plant growth, biomass accumulation, plant development, yield and yield components of barley crops under a field organic farming system [ 9 ]. Moreover, barley plant growth promotion due to compost application as biofertilizer was associated with the expression of different genes involved in nutrient uptake and transport in both root and leaf tissues, indicating their potential role in increasing nutrient uptake, assimilation and translocation capacity of barley plant under organic fertilizers [ 9 ]. It is therefore important to gain a better understanding regarding the positive effect of date palm compost on the growth of barley using omics approaches for delineating molecular mechanisms of biological processes.…”

Effects of Date Palm Waste Compost Application on Root Proteome Changes of Barley (Hordeum vulgare L.)

“…Under drought stress conditions, several studies have reported positive effects of compost incorporation to increase the water-retention capacity of soil, which may lead to an increase in growth and yield in crops such as canola [ 9 ] and wheat [ 10 ]. In this context, the application of date palm waste compost at 30 t ha −1 induces the expression of nutrient transporter genes in roots of barley, which leads to improved macronutrient uptake by the plant and then promotes plant growth, plant development, yield and yield components of barley grains [ 11 ]. Furthermore, the use of compost in agriculture stimulates plant immunity against pathogens, leading to a higher crop yield.…”
