“…The effect of growth environment on lucerne productivity is often reported (e.g. Lamb et al 2014, Chmelíková et al 2014, however, observed CR effect could not be simply contributed to climate and is probably also connected with soil conditions. In contrast to CR 4, the CR 0, 1, and 2 with warmer climate (8.5-9.5°C), similar precipitation (500-550 mm), and usually more fertile soils (Chernozems, Luvisols) provided yield between CR 3 and 4.…”

The aim of this study was to investigate the impact of used technology and environmental condition on lucerne dry matter yield in the regional conditions. During a three year period (2011)(2012)(2013), the investigation was based on management survey in 27 farms in the Czech Republic. Climate conditions significantly influenced yield in some interaction with soil where only combination of dry climate and less fertile soil conditions reduced forage yield. The single soil effect was not significant for forage yield. Applied technology was influenced by both environment and farm characteristic (such as farm size and cow's milk performance) which together significantly explained about 40% of variability of used technological properties. From all investigated technological properties, only cultivation of lucerne in mixture with grasses consistently increased forage yield therefore should be considered as important factor for modelling forage farm yield in the regional conditions.

“…To describe the production potential of each sampling plot, background information on the total yield and the average biomass of below‐ground organs in the upper 30 cm soil layer from Chmelíková et al (2014) were added to Table 1. The three cuts contributed with 45%, 36%, and 19% to the total herbage yield.…”

“…The aim of this study was to investigate T. pratense plant traits in grass–legume mixtures during a complete growing season under field conditions of organic farming. Simultaneously, a study under the same conditions and with the same investigation method was carried out on alfalfa ( Chmelíková et al, 2014). This provides the opportunity to discuss the two most important legume species with respect to their suitability for different soil conditions.…”

Grass–legume mixtures are suitable for crop rotations in organic farming. However, seasonal development of below‐ground organs of Trifolium pratense in mixtures and on different soils was neglected. We asked (1) how the diameter of the root neck, the maximum order of branching as well as (2) the nodule traits are affected by locality and time, and (3) how above‐ground plant traits of red clover vary in space and time. Red clover was investigated in grass–legume mixtures in the first year of vegetation. Five sites in S Germany were sampled at the day of cut at the end of May, the beginning of July, and at the end of August, respectively. Under similar climatic conditions root traits (diameter of the root neck, order of root branching, size of nodules, and proportion of senescent nodules) differed with soil conditions and time within the season. Root diameter increased during the season. Higher sand content fostered root branching and branched roots developed more nodules. Thinner roots had more active nodules (pink). Root diameter and non‐active senescent (green) or moribund (brown) nodules increased at the end of season. Nodule activity differed more according to season than to soil conditions. The number of nodules per plant (12.5–19.5) decreased from May to August. Cylindrical nodules were found on 85–100% of the plants and branched nodules only on 0–25%. The height of plants was lowest in May and increased in July. The mean number of stems per plant (3.3–6.3) was highest in August. Understanding red clover traits and N2 fixation is interesting scientifically as well as agronomical. Organic and conventional farmers can both benefit of our findings.

“…Low P and K soil fertility reduced fibre concentrations in the forage (Lissbrant et al 2009) as well as persistence and productivity (Berg et al 2007). As was highlighted by Chmelíková et al (2015), holistic analysis including above-and belowground traits should be used for the evaluation of fodder crops. Therefore, further research is warranted to identify the influence by which long-term fertilization…”

Effects of direct fertilization on lucerne (Medicago sativa L.) forage yield have been widely investigated; however there is a lack of published studies investigating the long-term effect of indirect application of mineral and organic fertilization. The main objective of the present research was therefore to investigate differences in forage yield under different combinations of mineral (6 treatments) and organic (3 treatments) fertilization over the past 8 years of long-term experiment conducted since 1955 in Ruzyně. Long-term absence of fertilization provided average annual dry matter yield of 8.64 t/ha. Indirect application of single manure or slurry significantly increased yield to 9.68 and 9.37 t/ha, respectively. Absence of mineral fertilization provided yield of 9.23 t/ha across organic fertilization and an inconsistent effect of the increase of indirectly applied nitrogen (N) rate was observed. The highest yields over 10 t/ha were observed at treatments where combinations of organic fertilization with higher rates of N, phosphorus (P) and potassium (K) were applied. The trend for yield reduction was observed under increasing N rates within identical P and K fertilization. This research has shown that indirect effect of fertilization should be considered together with stand age when lucerne forage yield is evaluated.
