Effect of Liquid Organic Humate Fertilizer Humustim on Chemical Composition of Spring Forage Pea

Abstract

Effect of liquid organic humate fertilizer Humustim on chemical composition of aboveground biomass, root biomass and grain of spring forage pea was studied at the Institute of Forage Crops, Pleven, Bulgaria (2002Bulgaria ( -2004. Presowing treatment of seeds and treatments during vegetation were applied. The treatment with Humustim increased content of crude protein, macro elements and water-soluble carbohydrates in the aboveground biomass of plants. The highest content of crude protein (13.69%) and water-soluble carbohydrates (8.40%) was found for presowing treatment with Humustim at the dose of 1.2 L/t seeds + one treatment during vegetation. Applying of Humustim decreased crude protein content in roots from 5.0% to 17.8%. Treatment with Humustim had no effect on crude protein content in grain and increased water-soluble content (from 3.3% to 10.0%) and Са (from 11.1% to 77.8%). Better growth and development of spring forage pea were observed after treatment with Humustim-plant height and root length increased.

“…Setaria splendida Stapf which is harvested at 45 days and fertilized with liquid organic fertilizer mixed with water at a ratio of 1: 1 has provided levels of dry matter that can be accounted for by 15 [5,25]. The nitrogen content of traditional market liquid organic fertilizer wastes contributes to existing results [4].…”

“…The negative impact of traditional market organic waste can produce tangible benefits. The advantage of using liquid organic fertilizer in agricultural activities is that the nutrients are easily absorbed by plants and are easy to use [4]. Setaria splendida Stapf is one of the superior feed plants for ruminant livestock sources favored by livestock [5].…”

Ways to increase the productivity of crop rotation in the forest-steppe conditions of the European part of Russia

“…The provision of expanded reproduction of soil fertility in modern conditions is becoming decisive not only in preserving the potential of the land, but also in the constant growth of production of ecologically clean grain, fodder, vegetables and other agricultural products [1][2][3][4][5][6].…”

The effect of growth regulator Tytanit dose on Medicago x varia T. Martin and Trifolium pratense L. yield and nutritional value

“…The solution for this state of affairs is integrated farming, which can reduce use of chemical products in plant-growing technologies, replacing them with biostimulants and other substances. Therefore, new effective methods and environmentally friendly solutions are needed to improve the health and quality of plants ( Ilieva and Vasileva, 2013 , Janas et al, 2013 , Serrano et al, 2004 , Szparaga et al, 2018 , Kocira et al, 2019 , Vasileva et al, 2017 ). One of such biostimulants is Tytanit ( Godlewska and Ciepiela, 2018 , Malinowska and Kalembasa, 2012 , Radkowski and Radkowska, 2013 , Radkowski et al, 2015 , Wadas and Kalinowski, 2017a ), the active ingredient of which is titanium (Ti).…”
