“…Organic fertilizers also act to form organic acids, which reduce the degree of soil interaction in the plant rhizosphere. This is thought to act to increase the preparation and availability of necessary nutrients such as N and P, and these results are on the one hand consistent with El [6]. Adding organic fertilizer to the soil increased nitrogen and raw phosphorus in the soil.…”

This study aimed to coexist with salinity by using water of different salinity in the presence of decomposed animal manure. Experiments were conducted at the Agricultural Station/Agricultural Research Office in Iraq to study different water types in the presence of increasing animal organic fertilizers. Nutrient preparation and barley plant growth and production. The experiment was conducted in the design (RCBD) The results showed the superiority of 35 t ha−1 of animal organic fertilizer as the nitrogen and phosphorus availability EC in the soil was 45.11, 25.68 mg kg−1, and 3.99 dS m−1. The 35 t ha−1 organic fertilizer treatment also had better characteristics (plant height, 1000 grain weight, grain yield, biological yield), (66.15 cm, 43.88 grains, 2.96 μg ha−1, and 10.99 μg ha−1) was given each. Comparison with control treatment. Irrigation water treatment resulted in a mixture of 3.3 dS m−1, which was higher than 6.5 dS m−1 for saline water treatment and lower than 1.4 dS m−1 for sweet water treatment. There were no significant differences in all the characteristics, and the values of (nitrogen and phosphorus availability, EC, weight of 1000 grains, grain yield, biological yield) were (36.89, 20.99 mg kg−1, 63.05 cm, and 38.58). cereals, 2.74 and 9.65 µg ha−1, respectively).

“…Additionally, in the absence of adequate potassium fertilization, significant soil K deficiency occurs [15]. Halillat [21] and Belaid [22] have shown that potassium fertilization has a favorable effect on agronomic behavior, including certain characteristics of durum wheat, such as yield and thousand-grain weight.…”

Investigating the Potassium Fertilization Effect on Morphological and Agrophysiological Indicators of Durum Wheat under Mediterranean Rain-Fed Conditions

It is well known that balanced and optimal mineral fertilization (i.e., nitrogen, phosphorus, and potassium) can increase yield and improve wheat quality. However, there is little scientific knowledge on the specific effect of potassium (K) fertilization on the morphological and qualitative characteristics of rainfed durum wheat under Mediterranean conditions, especially in the context of Algerian agriculture. Therefore, the main objective of this study is to provide crucial information on this important type of durum wheat mineral nutrition for farmers and researchers working in similar areas. The field study was conducted in the Northern Algerian region of Mitidja during the 2020/2021 and 2021/2022 growing seasons. The effect of K fertilization was evaluated within five contrasted rates of K: 0 kg k2O ha−1, 100 kg k2O ha−1, 200 kg k2O ha−1, 300 kg k2O ha−1, and 400 kg k2O ha−1, which were applied on one of the most commonly cultivated cultivars of durum wheat (Simeto). Results showed that increasing potassium levels had a positive and significant impact only on grain yield, spike length, spike neck, and dry matter. Hence, the highest grain yield of durum wheat (2.58 t ha−1) was demonstrated under low K application (100 kg k2O ha−1). This rate leads to an increase in grain yield by more than 0.6 t ha−1, as compared to the unfertilized control. Moreover, the thousand-grain weight of durum wheat was significantly increased by 4.11 g and 1.96 g, respectively, under low and moderate (200 kg k2O ha−1) K-fertilization, as compared to the control. In terms of grain yield quality, low K application provides an increase of 1.21% in protein content as compared to that measured under the control treatment. The major finding confirmed that both growth and yield indicators of durum wheat were globally optimized under low K application. Based on grain yield and evaluated agronomic traits, this research revealed that an applied K rate of 100 kg k2O ha−1 is recommended as the most effective dose to maximize durum wheat yield and quality under Algerian sub-humid conditions.
