Abstract:

Fodder galega (Galega orientalis Lam.) is a forage legume that has been grown in Estonia for almost forty five years. Pure galega is known to be persistent, high-yielding crop and rich in nutrients, in particular crude protein (CP), neutral detergent fibre (NDF) and acid detergent fibre (ADF). Galega is usually grown in a mixture with grass in order to optimize its nutrient concentration, increase dry matter (DM) yield and improve fermentation properties. The trial plots were established on a typical soddy-calcareous soil. There are certain grass species suitable for the mixture. In this study galega mixtures with reed canary grass cv. ‘Marathon’, timothy cv. ‘Tika’, red fescue cv. ‘Kauni’ and festulolium cv. ‘Hykor’ were under investigation in three successive years (2013–2015). In order to increase competitiveness of grasses and the yield of the first cut, two N fertilization levels were used: N0 and N50 kg ha-1. Two cuts were carried out during the growing season in all three years. The total dry matter yield varied from 9.1 to 12.8 t ha-1. The NDF concentration in the DM varied from 495−559 g kg-1. Both DM-yield and NDF were dependent on the year, mixture, cutting time and fertilization. Nitrogen fertilization (N50 kg ha-1) favoured grass growth and reduced the role of galega in the sward.

Abstract:

Abstract Different sowing rates, row spacing, optimal and reasonable mixtures of herbicides were investigated for the seed production of the Estonian fodder galega Gale (Galega orientalis Lam.). The control of dicotyledonous weeds with herbicides is well justified in the year of sowing because the control remains insufficient in the years of seed production. However, the control of weeds in the years of seed production diminishes the expenditures for seed gathering, drying and cleaning. The control of couch grass is necessary to avoid ergot sclerotia in seed production and gives good results in the years of seed harvesting. The average seed yield of fodder galega was 259 kg ha-1 Desicant Basta 150 SL (glyfosinate-ammonium 158 g l-1) with rate of 1.0 l ha-1 was used before seed harvesting in order to dry the green parts of plants, to favour uniform ripening and to diminish the losses in seed harvesting, which gave an extra yield of 35%. Due to a higher competative ability of weeds, it is expedient to use a bigger sowing rate in the ecological farming, i.e. 10 kg ha-1.

Abstract:

The fluorescence measurement in situ of various developmental levels of leaves and various cultivars of fodder galega (Galega orientalis Lam.) was carried out at the Research Station of the Lithuanian University of Agriculture. The object of the investigation was to evaluate the differences of fluorescence of galega cultivars Vidmantai, Laukiai, Melsviai and a breeding number L04–4. The estimation of fluorescence efficiency characterizes the intensity of photosynthesis indirectly and is related to biosynthesis. The yield of the synthesized biomass was also determined. The most intensive fluorescence yield value of the 2nd and the 3rd leaf ranks and plants was determined at the flowering stage in situ. The indices of fluorescence (fluorescence in steady–state light Ft and maximal fluorescence Fm, quantum yield of electron transport Y and electron transport rate ETR) were smaller in a lower leaf rank and in more old leaves of the galega cultivars tested. All quantities of the investigated fluorescence indices statistically significant (P = 0.95) decreased and reached the minimal value both of the older leaves (the 4th–the 6th leaf ranks) and of the youngest (the 1st rank) leaves in comparison with the peak values of the 2nd and the 3rd leaf ranks of all investigated cultivars. It was established that a strong and statistically significant parabolic curvature (0.78145 ≤ η ≤ 0.97385) of different leaf ranks depend on fluorescence indices Ft, Fm and Y/ETR with a leaf rank predomination by 60.3–86.0, 67.2–84.9 and 62.8–94.8% respectively.
