“…Total dry matter yield during that season showed a numerical increase in yield but was not significant ( P > 0.05). Rannnah et al (1984), Haby and Leonard (2005), and Kheirkhah et al (2016) reported positive impacts of B on alfalfa production. However, our data showed B fertilization did not influence total yield of alfalfa in either year.…”

Core Ideas Boron (B) application increased petiole B in irrigated alfalfa but did not impact yield and quality. Low initial soil B is not a reliable measure of the need to amend with B using foliar application of irrigated alfalfa in Montana. Diagnosing signs of B deficiency coupled with in‐season petiole B analysis may be of better value to the producers. A boron (B) deficient soil may negatively impact irrigated alfalfa (Medicago sativa L.) plant tissue sufficiency, thereby compromising yield and quality in a short‐season environment such as Montana. The objective was to determine the impacts of B fertilization on irrigated alfalfa yield and quality in 2015 and 2016 at Creston and Dillon, MT on fine sandy loam and silt loam soils, respectively. The initial soil B levels at the Creston and Dillon sites were 0.2 and 0.8 ppm, respectively. The study was conducted as a randomized complete block design with five B levels: (1) 0; split applications of (2) 0.50, (3) 1.00, (4) 2.00; and a one‐time application of (5) 2.00 lb/ac in four replications. Full doses of Treatment 5 and half the dose of Treatments 2–4 were applied in early spring at a 3‐inch regrowth height. The other half dosage of Treatments 2–4 was re‐applied at a 3‐inch plant height after the first cutting. A liquid 10% B AgriSolutions was foliar‐applied as B fertilizer. All the cuttings were performed at 10% bloom. Application of B increased (P < 0.05) plant B concentration at both locations. Boron fertilization increased (P < 0.05) crop yield for the second cutting in 2015 at Dillon but did not influence all of the other seasonal cuttings nor total yields for either year or location. No significant effect of B on forage quality was observed. This research suggests foliar B fertilization based on a low B soil test is not beneficial for irrigated alfalfa producers in Montana.

“…Weeds are a suitable host for insect pests and compete with plants for nutrient absorption; thus, weed removal reduces the population of the EAW, Hypera brunneipennis 12 . Calcium super phosphate, potassium sulphate and microelements spraying play an important role in nutrition of the plants 13 . Therefore, farmers should use these treatments and safety insecticides to reduce both the population density of the EAW, Hypera brunneipennis , to get healthy plants and preserving the environment.…”

BACKGROUND: The Egyptian alfalfa weevil, Hypera brunneipennis causes damage on different parts of alfalfa plants. Therefore, four agricultural treatments are carried out included calcium super phosphate addition (15.5% P 2 O 5 ), potassium sulphate addition (50% K 2 O), microelements spraying and hand removing of weeds to reduce the population of the Egyptian alfalfa weevil and increase both the final yield and obtain a healthy plant. RESULTS:The treatment of calcium super phosphate (15.5% P 2 O 5 ), potassium sulphate (50% K 2 O), microelements spraying and hand removing of weeds gave less infestation of Egyptian alfalfa weevil [4.38 and 4.89 (larvae and adults/m 2 )] and the highest total fresh (70.08 and 74.52 ton/feddan), dry yield (19.37 and 19.70 ton/feddan) and plant height yield (60.00 and 61. 17 cm) in first and second seasons, respectively, with significant differences compared with the other treatments and the untreated check. Also, the same treatment gave the highest net benefit over untreated check 29.06 and 31.93 (thousand L.E./feddan) and net benefit/costs ratio/feddan (1.77 and 2.22) in first and second seasons, respectively. CONCLUSIONS: Good agricultural treatments of calcium super phosphate addition (15.5% P 2 O 5 ), potassium sulphate addition (50% K 2 O), microelements spraying and hand removing of weeds play an important role in obtaining a healthy plant, reducing Egyptian alfalfa weevil infestation, and increasing total fresh yield, total dry yield, and plant height of alfalfa.

“…Microelements perform specific roles in plant metabolism, influence the enzymatic reactions, the physicochemical properties of the plasma colloids, and the use of nutrients (such as nitrogen, phosphorus, and potassium). Among microelements, the most important in the alfalfa exchange processes are cobalt and molybdenum (Walworth & Summer, 1990;Kheirkhah et al, 2016). In the case of a decreased content of cobalt in the fodder (less than 0.07 mg/kg of dry weight), the productivity of farm animals reduces sharply, along with the weight gain and the milk yield.…”

“…Cobalt deprivation may further cause severe disease in the cattle that is called pining, which affects cattle. The cattle lose appetite, and overall weakness is observed; the hairs become rough and hard; the content of hemoglobin in the blood decreases since cobalt is contained in vitamin B 12 and is involved in hemoglobin formation (Gorkovenko, 2012;Kheirkhah et al, 2016). Microelements are important for forming the symbiotic apparatus in terms of nitrogen fixation; they stimulate the activity of nodule bacteria (Chuyanova, 2016).…”

The effect of phosphorus fertilizer on the yield of new alfalfa cultivars Kokorai, Osimtal, and Kokbalausa has been identified after the introduction of P 0 , P 150 , and P 200 (active substance) with nitrogen N 60 , potassium K 70 , microelements (cobalt (Co), molybdenum (Mo)) on the three noted phosphorus backgrounds. Increasing the dosages of phosphorus increases the yield of the green mass of the three cultivars on various backgrounds without the introduction of any other types of fertilizers on average by 126.6% with P 150 , and by 35.9% with P 200
