Influence of Pre-Sowing Application of Mineral Fertilizers, Root and Foliar Nutrition on Productivity of Winter Tritical Plants

Abstract

The purpose of the research was to develop and scientifically substantiate the system of nutrition of winter triticale crops to optimize their production process and increase plant productivity in the Northern Steppe of Ukraine. The highest number of grains in the ear of the main and lateral stems of winter triticale was in the variants where foliar nutrition with a mixture of carbamide, magnesium sulfate and complex fertilizer Ferkrystal Summum during the 31st and 39th microphases and the variants where the third foliar nutrition during the 73-th microphase on the background of root application of ammonium nitrate at a dose of 150 kg/ha was conducted. In these variants, the number of grains in the ear on average over the years and variants for pre-sowing fertilization was 40.6 and 40.0 pieces, respectively, which is 11.2 and 11.5%, respectively, more than in the control. Carrying out three foliar nutrition with a mixture of carbamide, magnesium sulfate and complex fertilizer Fercrystal Summum on the background of root nutrition of ammonium nitrate during the 22nd microphase provided an increase in grain weight from the ear and lateral stems of winter triticale compared to the control (application of ammonium nitrate at the dose of 150 kg/ha on frozen thawed soil) by 0.24 and 0.23 g, respectively, or by 14.8 and 15.4%. The studied variants of pre-sowing application of mineral fertilizers significantly affected the parameters of productive plant stand (the number of plants and lateral productive stems), while nutrition provided significant changes in the parameters of grain productivity of winter triticale plants.On the basis of the researches, during winter triticale cultivation, the farms in the Northern Steppe of Ukraine are recommended to carry out pre-sowing application of ammophos (N 12 P 52 ), to apply ammonium nitrate (N 50 ) for roots in the 22nd microphase in spring and carry out two foliar nutrition in the 31st and 39th microphases with a mixture of carbamide (N 10 ), hepatic magnesium sulfate (1.5 kg/ha) and complex water-soluble fertilizer Ferkrystal Summum.

Impact of Different Nutrient Management Strategies for Nitrogen, Phosphorous and Potassium Uptake and Availability in Chilli (Capsicum annuum var. annuum L.)

“…The increase in available N in soil could be due to conjoint application of NPK, biofertilizer and organic inputs. The presence of vermicompost might have resulted in release of more nitrogenous substances in the soil and might have increased the efficiency and effectiveness of soil to hold the nutrients as reported by [21,22]. Mixing of N fertilizer with organic manures might have reduced the nitrogen losses, improved the fertilizer use efficiency thus, increasing the availability of N. Similar results were also reported by Singh et al [23,24,15].…”

“…A cursory glance at the data in Further, it was also observed that all treatment combination at 75% NPK level and 100% NPK (T1) and natural farming practice showed nonsignificant among themselves for available K in post-harvest soil. The available K content increased due to addition of organic manure and biofertilizers along with NPK which helped in the release of unavailable form of potassium to available form in the soil solution and increased the potassium content in the soil [21]. The beneficial effect of vermicompost and farm yard manure on available K may be ascribed to the direct potassium addition to the potassium pool of the soil besides the reduction in potassium fixation and its release due to interaction of organic matter with clay particles [25].…”

Chisel Tillage Under Spring Barley in the Forest-Steppe

“…Treatment methods had a different effect on crop weed infestation. This is confirmed by Bielashov et al (2022) and Kuts et al (2021). For example, in the tillering phase of barley during ploughing, the number of weeds was 9.8 pcs•m -2 when the N 30 P 30 K 30 fertilizer was applied and 11.1 pcs•m -2 when the N 60 P 30 K 30 fertilizer was applied.…”

Ecological safety of sunflower seeds in the conditions of agricultural intensification

“…According to O. Bielashov et al (2022), the use of phytoremediation properties of sunflower should be balanced, since the absorption of pollutants by sunflower plants, their accumulation and entry into the food chain can cause various human diseases. Y.…”
