Response of potatoes planted in Gypsifrious soil to organic, biological and mineral fertilization

Abstract

This experiment was conducted during the growing season 2021, the spring bloom, in the AL-Falluja date palm research station province fellow Horticulture board/Ministry of Agriculture. To study the effect of organic fertilizer and inoculation on P. pseudomonas bacteria and fungi. Trichoderm harzanium and mineral fertilizer in the growth and yield of potato variety Burren, the experiment included three factors, the first factor, adding two levels of fermented organic fertilizer 10 tons hectares of sheep waste (C1) and without addition of organic fertilizer (C0) As for the second factor, it included the addition of biological fertilizer (Pseudomonas and Trichoderma bacterial vaccine): without adding the vaccine B0 + adding the bacterial vaccine Pseudomonas B1 + adding the fungal vaccine Trichoderma (B2) and the addition of a mixture of the bacterial Pseudomonas vaccine and the fungal Trichoderma vaccine (B3), and the third factor was the addition of three levels of mineral fertilizer, which is 50 % of the recommended fertilizer (M50) and 75% of the fertilizer recommendation (M75) and the addition of the fertilizer recommendation 100 % (M100) and the results of the study are summarized as follows: The use of organic fertilizer led to a significant increase in growth characteristics and yield of potatoes as a result of the addition of fertilizer aleudwiu Treatment O1 gave the highest rate of the studied traits, number and weight of tubers, which amounted to 7.91 tubers. plant-1 and 78.03 g. Plant-1 and the yield of one plant is 634.9 g.Plant-1, and the total yield is 36.91 mg.h-1 The total marketable yield 35.53 mcg ha-1. There was a significant increase in the growth characteristics and yield of potato plants due to the addition of bio-fertilizer, as it gave the interaction treatment between Pseudomonas bacteria and Trichoderma (B3). The highest rates in the studied traits, as the number and weight of tubers, reached 9.11 tubers. plant-1 and 86.22 g. Plant-1 and the yield of one plant is 796.0 g. plant-1 The total yield is 39.03 mcg ha-1 and the total marketable yield is 37.71 mcg ha-1. The addition of the fertilizer M100 led to a significant increase in the growth characteristics and yield of the plant Potatoes, as the number and weight of tubers reached 8.10 tubers: plant-1 and 76.88 g. Plant-1 and the yield of one plant is 634.9 g.plant-1, total yield 36.26 mcg ha-1, total marketable yield 35.05 mcg ha-1. The double and triple interactions increase the results in growth characteristics, chemical content, growth characteristics and yield Keywords: potatoes, organic fertilization, bio fertilization, mineral fertilization, yield.
