Effects of fertilisers on pulse crop productivity and nitrogen assimilation on acid soil

Abstract

This research aimed to compare the productivity of three species of pulse plants (Vicia faba L., Pisum sativum L., Lupinus angustifolium L.) in acidic sandy loam soil and to determine the influence of NPK (N0P0K0, N0P27K73, N30P27K73) fertilisers on grain yield and nitrogen assimilation. The experiments were conducted Voke Branch of Lithuanian Research Centre for Agriculture and Forestry (Baltic Sea region, 54°33'49.8''N, 25°05'12.9''E) in 2016–2018. Fertilisation with PK increased the grain yield of Vicia faba L. and Pisum sativum L. (P < 0.05) and had no effect on the yield of Lupinus angustifolium L. (P > 0.05). Nitrogen fertilisers only increased the yield of Pisum sativum L. grain, reduced the yield of Lupinus angustifolium L. grain and did not affect Vicia faba L. The chlorophyll concentration in the leaves was significantly dependent on the species of plant. In acidic soil, Vicia faba L. and Lupinus angustifolium L. assimilated similar amounts of total nitrogen in the grain – 146.8–230.0 and 160.1–220.5 kgN/ha, respectively. Pisum sativum L. nitrogen assimilation was lower – 93.0–128.8 kg N/ha. The assimilation of total nitrogen in Pisum sativum L. was stimulated by the application of P27K73 and N30, and in Vicia faba L. – only by fertilisation with PK.

Dry matter production, nitrogen yield and estimation of nitrogen fixation of legumes on vertisols of the Ethiopian highlands

“…For soil fertility improvement, legumes play an essential role in the farming systems of resource-poor farmers. On the other hand, improving drainage increases nutrient efficiency and availability ( Tripolskaja and Asakaviciute, 2019 ). However, growing legumes during the long rainy season can reduce biomass productivity and nutrient uptake ( Arduini et al., 2019 ).…”

“…Positive and negative N balances were detected, with significant differences between crop types, P application, land preparation methods, and over years. Climatic factors, soil management practices, and soil mineral N in the soil determine the N balance in a system ( Tripolskaja and Asakaviciute, 2019 ; Sainju, 2017 ; Sainju et al., 2017 ). Soil nitrate, crop characteristics, dry matter yield, and the N harvest index can also influence the N balance.…”

Characterization of Vertisols Fertility Status and Their Implications on Chickpea (Cicer arietinum L.) Farming in Semi-Arid Areas of Itigi District in Tanzania

“…Chickpea, just like other agricultural produce, benefit farmers in meeting quality protein requirements and enhance the potentiality of the agricultural sector through its ecological significance through assimilation of soil nitrogen and reduction of the excessive use of mineral fertilizers [5]. Legumes including chickpea improve soil productivity when cereals are grown on the same field after their harvest [6].…”
