Impact of lime and NPK fertilizers on yield and quality of oats on pseudogley soil and their valorisation

Abstract

In order to determine the effect of fertilization, environment, and their interactions on the yield and oats yield components. Five fertilization treatments (T1-control, T2-80 kg N ha-1, T3-120 kg N ha-1, 80 kg P2O5 ha-1 and 80 kg K2O ha-1, T4-N120P80K80 + 5 t ha-1 of lime and T5-N120P80K80 + 5 t ha-1 of lime + 30 t ha-1 of farmyard manure) were examined during three growing seasons in Kraljevo location in Western Serbia. Grain yield (GY), 1000 grain weight (TGW), hectolitre weight (HW), plant height (PH), panicle length (PL), number of grains per panicle (NGP) and protein content (PC) were analysed. The aim of the study was to determine the effect of organic and mineral fertilization and calcification on the yield and oats yield components. On average, for all fertilizer variants, during the three-year trial, the highest yield of oats 3802 kg ha-1 was obtained in the fertilizer variant with the combined application of NPK fertilizers, lime and manure. Positive highly significant correlation, during in the study trial were found between yields with PH, PL and NGP. Negative and highly significant dependencies were found between protein content with GY, PH and NGP. The results of these studies indicate the importance of rational introduction of adequate quantities of fertilization, calcification and humization in order to make oats as profitable as possible in the agro-ecological conditions in Pannonian Environments.

Analysis of Climate Elements in the Northeastern Region of Croatia for the Purpose of Determining Irrigation Requirements of Maize and Soybean on Drained Soil

“…The present results confirm the statement of many authors that the traits analyzed, and their correlations are genetically determined but are strongly modified by the nutrient status of the environment and weather conditions (Djekic et al, 2014;Lakic et al, 2018;Rajicic et al, 2020aRajicic et al, , 2020b.…”

Influence of amelioration on the productivity of alfalfa on acid soil types vertisols

“…Long-term inadequate application of mineral fertilizers can also significantly affect soil acidity . Also, long-term use of urea contributes to soil acidification (Popović et al ., 2019;Rajičić et al ., 2020) . The problem of acid soils is significantly important for soils in southern Serbia .…”

“…Taking into consideration the fact, that acid soils cover an increasing part of agricultural land, the production capacity is significantly reduced . Reduced intake of organic matter combined with the increasing use of exclusively mineral (nitrogen) fertilizers have also contributed to the more intensive process of soil acidification over the past decades (Đekić et al ., 2014;Jelić et al ., 2017;Gudžić et al ., 2019;Terzić et al ., 2019;Rajičić et al ., 2020) . Soil acidity affects crop sprouting, early germination, and total biomass production, that is, the production of dry matter of roots and aboveground parts (Zhang et al ., 2004(Zhang et al ., , 2006 .…”

“…Numerous researches in our country, as well as throughout the world, indicate that adequate application of lime materials in combination with organic and mineral fertilizers is the most efficient way to eliminate unfavourable production properties of those soils with poor physical and chemical properties (Jelić et al ., 2013;Rajičić et al ., 2020) . There is an increasing need for the determination of fertilization and cultivation systems that will be adapted to both the soil and climatic conditions of all production areas with acid lands (Stevović et al ., 2010;Đekić et al ., 2014;Jelić et al ., 2015;Terzić et al ., 2018;Gudzic et al ., 2019;Popović et al ., 2019;Biberdzic et al ., 2020;Rajičić et al ., 2020) .…”

“…In the structure of the total used agricultural land of the Republic of Serbia, intensive ways of using of arable soil prevail (Karapandžin and Bošnjak, 2014), thus affecting the additional impact on soil resources which is reflected in the loss of organic matter, soil compaction and deterioration . The application of large amounts of mineral fertilizers and pesticides, which are considered environmental pollutants, as well as the poor management of crop residues and insufficient application of organic fertilizers, makes soil degraded and its fertility significantly decreased (Đekić et al ., 2014;Jelić et al ., 2017;Gudžić et al ., 2019;Popović et al ., 2019;Terzić et al ., 2019;Rajičić et al ., 2020) . The above-mentioned reasons require changes in traditional agriculture activities, which will lead to a reduced negative impact on the environment .…”
