Productivity of the Green Mass of New Alfalfa Cultivars Depending on the Effect of Macro- and Microfertilizers on Various Phosphorous Backgrounds

Abstract

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

Effect of the Biological Preparation Phytop 8.67 on the Quality and Yield of Rice in Saline Soils

“…As a result, the application of mineral fertilizers of biological origin, where the most important are the latest micro fertilizers, provides at least half of the resulting total yield growth (Dzhamantikov et al, 2018;Toktarbekova et al, 2020;Ivanov et al, 2021).…”

Productivity of indigenous alfalfa (Medicago sativa) cultivar depending on agricultural practices on sierozem soils in South Kazakhstan

“…Alfalfa stimulates recovery of soil fertility and structure, protects sloping land from water erosion and prevents soil salinization on irrigated areas (Massaliyev et al, 2015) Yield of alfalfa under rainfed production depends mainly on the soil moisture available from rainfall. Alfalfa is one of the best preceding cover crop in a crop sequence for all crops and is included in all types of crop rotations recommended for rainfed areas in South Kazakhstan Province (Toktarbekova et al, 2020). Alfalfa gives rich harvest of hay and seeds for four years of its life-cycle, followed by a decrease in yields caused by strong thinning of herbage and infestation from ephemeral weeds.…”

Genetic Diversity of Perennial Wild Species of Alfalfa Subgenus Falcago (Reichb) Grossh. in Kazakhstan and Their Involvement in the Breeding

“…The wild alfalfa species are used to create source material for alfalfa breeding for adaptability to drought, resistance to diseases, saline soils, and winter conditions using their germplasm based on their hybridization with the cultivated M. sativa L. species (Humphries et al, 2021;Krasteva, Uzundzhalieva, & Ruseva, 2012;Toktarbekova, Meiirman, Yerzhanova, Abayev, & Umbetov, 2020). Their use is associated with studies in the following areas and stages: (1) collecting wild-growing alfalfa species at the level of their ecotypes and studying them in the cultivation conditions in the introduction nurseries for isolating the initial forms; (2) surveying the proposed territory through a local expedition for identifying introgressive (hybrid) forms in the formbuilding process arising from free hybridization in the foci of their joint growth.…”
