Effect of poultry manure on the yield and nutriments uptake of potato under saline conditions of arid regions

Abstract

In hot arid lands, soil salinity, irrigation with brackish waters and the massive use of mineral fertilizers are major constraints for the development of potato cropping. The current field experiment was conducted in the Sahara Desert of Algeria in order to highlight the effect of organic fertilization on the improvement of potato production and the increase of plant salt-stress tolerance. The variation of yield production parameters and nutritional status of plants were evaluated through a split-plot design including six increasing rates of poultry manure (PM) (0, 20, 30, 40, 50, 60 mt/ha) tested in three experimental sites with increasing salinity levels: low saline soil (electrical conductivity 'EC' = 0.9 dS/m), saline soil (EC = 2.2 dS/m) and high saline soil (EC = 5.9 dS/m). The results revealed a significant and proportional increasing of all studied yield parameters (number, seize and yields of tubers) with the increase of PM rates compared to the control. The effect of the interaction (PM × salinity level) showed that the highest yield (44.55 mt/ha) was recorded in plots treated with 60 mt/ha of PM in high saline soils. The assessment of nutritional status at flowering stage of potato plants demonstrated that concentrations of K+ and N increased while Na+ concentrations decreased, in both leaves and roots, as PM rates increasing, principally beneath high salinity level. Our findings suggest the dose of 60 mt/ha of PM is an optimal amount producing the best tuber yields under saline conditions in arid soils.

Effect of Irrigation with Diluted Seawater on Coriander Growth and Soil Properties of Sandy Soil Amended by Chicken Manure and Biochar

“…Other investigators reported that organic fertilization enhanced salt tolerance of some vegetable crops under saline conditions. In this regard, Oustani et al, (2015) revealed a significant and proportional increasing of all studied yield parameters of potato with the increase of poultry manure rates compared to the control under saline conditions. Chicken manure mineralized faster than alternative animal manure; hence it releases its nutrients for plant uptake and utilization rapidly.…”

Behavior of some Local and Foreign Tomato Hybrids under Organic Fertilization and High Salinity Water Conditions in El- Arish-North Sinai

“…as well as total fruit yield (A+ B ton per fed.). In this respect (Oustani et al, 2015) found that the improvement of yield parameters of potato following fertilization with high rate of PM (60 m 3 ha -1 ) could be attributed to the improvement of both soil moisture retention and potentials of nutrient supply with macro and micro nutrients for the sandy soils., i.e. which it is the experiments site.…”

“…Application of ChM with high rates 150 and/or 120 kg N fed -1 which gave the highest values for most studied traits compared to addition of the same rates from cow manure in both seasons. (Oustani et al, 2015) on potato plant, found that the application of poultry manure at rate of 60 m 3 ha -1 produced the highest averages in all yield parameters i.e., number of tubers per plant, tuber size per plant, tuber yield per plant, and total tuber yield per ha -1 compared to adding of PM at rates of 20, 30, 40, and 50 m 3 ha -1 .,They also referred in their findings that the average of Na + contents measured in both potato leaves and roots proportionally and significantly decreased with the increase of PM rates.…”

“…in both seasons, However, The Local Eyeon hybrid was more responses to the high rates (150 Kg N fed -1 from ChM) this could give superiority for using local Eyeon hybrid under saline irrigation water, as well as the high rate of ChM, may stimulate the local Eyeon hybrid for saline water tolerance, this may be due to the content of organic fertilizer (ChM) from organic matter, macro and micro nutrients compared to cow manure content as shown in Table 3., in addition, the role of organic fertilizers for improvement of soil properties. (Oustani et al, 2015) reported that application of organic manures decreased the adverse effects of salinity on the potato yield.…”

Effect of Water Regime on Growth Performance of Durum Wheat (Triticum Durum Desf.) During Different Vegetative Phases

“…For the improvement of irrigated WP in wheat crops under the arid and semi-arid conditions of North Africa, it is proposed to: (i) apply three to four irrigations at the appropriate time of the growth season; (ii) control weeds; (iii) apply suitable doses of fertilizer. In this context, biofertilizer is demonstrated to offer better yields and resilient adaptation to plants grown under water and salinity stresses compared to mineral fertilizer (Boudjabi et al, 2015(Boudjabi et al, , 2018Oustani et al, 2015). Nakhforoosh et al (2016) consider that WP is a component of crop resistance to water stress which determines the yield.…”
