Poultry Manure and Humic Acid Foliar Applications Impact on Caraway Plants Grown on a Clay Loam.

Abstract

A field experiment was conducted at the Experimental Farm, Fac. of Agric., Al-Azhar Uni., Assiut, Egypt during two successive winter seasons of 2013/14 and 2014/15 to study the effect of poultry manure application (PM) and foliar application of humic acid (HA) on caraway plants growth and its yield constituents as well as some soil properties. Split plot design with three replicates was used. Four levels of PM (0, 10, 20 and 30 m 3 /fed) that were side banded in one dose before sowing and the recommended dose (RD) of NPK fertilizers were assigned to the main plots. Four humic acid levels (0, 1, 2 and 3 ml/L) as foliar application were allocated to the sub-plots. The results indicated that poultry manure, humic acid and recommended NPK dose treatments significantly increased vegetative traits (plant height, number of branches, and dry weight) of Caraway plants compared to untreated ones and could be arranged due to these increases in the order of poultry manure > recommended dose > humic acid. The highest values of vegetative traits, fruit and volatile oil yields in both season were recorded at highest level of both PM and HA (PM3HA3) followed by the recommended NPK dose with the highest level of HA (RDHA3) and then at the highest level of PM with the medium level of HA (PM3HA2). Moreover, poultry manure application, foliar application of humic acid and the recommended NPK dose significantly increased N, P, K, Fe, Mn and Cu contents of Caraway plants. Increasing the applied level of poultry manure or humic acid showed a positive effect on the soil organic matter content. The soil salinity (EC) were positively affected with using these studied materials since the EC of the soil increased with all treatments. On the other hand, the application of poultry manure or humic acid had a negative effect on the soil pH.

Effect of Foliar Spray with Proline and Humic Acid on Productivity and Essential Oil Content of Chamomile Plant Under Different Rates of Organic Fertilizers in Sandy Soil

“…Data illustrated in Table 3 show the effect of chicken manure and farmyard manure(FYM) combined with proline (Pro) and humic acid (HA) foliar spray on vegetative growth of Matricaria chamomilla L. during 2017 -2018 and 2018-2019 seasons. Mean comparisons revealed that addition of ChM at 20 m 3 fed -1 combined with HAfoliar spray at150 mgl -1 were the most effective treatments on both plant height (cm) and number of branches for both seasons, respectively(78.00, 79.33 and 24.00, 24.66).These results are in harmony with those found by (Awad, 2016) on caraway plants reported that the highest values of vegetative traits in both seasons were recorded at highest level of both poultry manure (PM) and humic acid (HA) followed by the recommended NPK dose with the highest level of HA.…”

“…Also, (Awad, 2016) on caraway plants found that increasing the applied level of humic acid or poultry manure recognized a positive influence on yields of fruit and volatile oil.…”

“…Also, Refs. [46][47][48] reported that the HA was effective in the evapotranspiration, gas exchange, and leaf uptake of nutrients. Nonetheless, VSC caused a greater increment of Pb (110%) in El-Madabeg soil.…”

Influence of different NPK fertilization levels and humic acid rates on growth, yield and chemical constituents of roselle (Hibiscus sabdariffa L.)

“…Humic acids are molecules that regulate many processes of plant development including macro and micro nutrient adsorption (Atiyeh et al, 2002). Furthermore, Awad (2016) suggested that foliar application of humic acid significantly increased N, P and K contents of caraway plants compared to untreated plants. Meanwhile, Bajeli et al (2016) showed that Japanese mint plants fertilized with organic manures recorded the highest values in volatile oil percentage compared to control.…”
