The Effect of Meat and Bone Meal (MBM) on the Seed Yield and Quality of Winter Oilseed Rape

Abstract

The aim of a two-year field experiment conducted in north-eastern (NE) Poland was to evaluate the effect of meat and bone meal (MBM) applied without or with mineral nitrogen (N) on seed yield, thousand seed weight (TSW), protein yield, fat yield, fatty acid profile and glucosinolate (GLS) concentrations in winter oilseed rape. Five treatments were compared: MBM applied at 1.0, 1.5, 2.0 Mg ha−1, inorganic NPK, and a zero-N check. The first two MBM plots and the NPK plots received supplemental inorganic N to provide a total of 158 kg N ha−1. The yields of winter oilseed rape were highest in the treatment with mineral (NPK) fertilization. All plots receiving MBM yielded equally to each other but greater than the unfertilized check. Winter oilseed rape accumulated significantly more protein in seeds in the NPK treatment than in the 1.5 Mg ha−1 MBM + 40 kg N ha−1 treatment. The crude fat content of seeds was significantly higher in the 1.5 Mg MBM ha−1 + 40 kg N ha−1 treatment, compared with the NPK treatment and the 1.0 Mg MBM ha−1 + 79 kg N ha−1 treatment. Oleic, linoleic, and α-linolenic acids accounted for nearly 90% of total fatty acids in rapeseed oil, and the average ratio of linoleic acid to α-linolenic acid was 1.81:1. Fertilization had a minor influence on the proportions of fatty acids, which were considerably affected by adverse weather conditions.

The Effect of Meat and Bone Meal (MBM) on Crop Yields, Nitrogen Content and Uptake, and Soil Mineral Nitrogen Balance

“…Nogalska and Załuszniewska [18] analyzed macronutrient (N, P, K, Ca, and Mg) concentrations in winter oilseed rape seeds and straw and their uptake by aboveground biomass (two-year means). Załuszniewska and Nogalska [19] determined seed yield, thousand seed weight, protein yield, fat yield, fatty acid profile, and glucosinolate concentrations in winter oilseed rape (two-year means). In the present study, data on winter oilseed rape (seed yield, straw yield, N content and uptake) were subjected to one-way analysis of variance (ANOVA) separately for each year (Section 2.7), similarly to data on maize and winter wheat, which were grown in a six-year crop rotation system on the same 20 plots; plot size was 20 m 2 (4 m × 5 m).…”

“…Long-term field experiments produce the most reliable results in terms of soil chemism and productivity, i.e., the yield and quality of agricultural crops. Some of the results relating to winter oilseed rape have already been published [18,19], as mentioned in the Materials and Methods section (Section 2.3). A research article describing the P content of plants and soil is currently being prepared for publication.…”

The Effect of Meat and Bone Meal (MBM) on Phosphorus (P) Content and Uptake by Crops, and Soil Available P Balance in a Six-Year Field Experiment

“…This study is part of long-term research (a six-year field experiment) investigating the influence of MBM on yield components, the chemical composition of crops, and selected properties of soil. The results regarding the yield and quality of winter oilseed rape [13,14]; the yields and N content of silage maize, winter wheat, and oilseed rape; and soil N balance [15] have already been published.…”

Seed Coating with Biowaste Materials and Biocides—Environment-Friendly Biostimulation or Threat?

“…To obtain PHs on the industrial scale, these materials are subjected to chemical, thermal and enzymatic hydrolysis [14]. It is worth noticing that animal collagen recently became an object of scientific interest due to its practical application allowing reduction in mineral fertilization and disposal of animal-processing wastes [11,15,16]. It was showed that PHbased biostimulants can improve agricultural production and satisfy global demands for environment-friendly crop management practices [17,18].…”
