Produkcja materiału szkółkarskiego na Podkarpaciu w ostatnich latach wykazuje tendencję wzrostową i w 2012 roku wynosiła ponad 3,8 mln sadzonek drzewek owocowych. Problem biomasy odpadowej z produkcji rolniczej i szkółkarskiej jest zagadnieniem o tyle istotnym, że każdorazowo zachodzi konieczność utylizacji odpadów. Nie w każdym przypadku jest to możliwe do zrealizowania w formie nawozu naturalnego. Zawsze jednak możliwe jest wykorzystanie energetyczne. Celem pracy była analiza energetyczna biomasy odpadowej powstałej z produkcji różnych gatunków drzewek owocowych. Przeprowadzono badania laboratoryjne, dotyczące kaloryczności poszczególnych gatunków podkładek do produkcji drzewek owocowych, a także zawartości popiołu oraz pierwiastków (C, H, N i S) w ich składzie chemicznym. Dokonano również oceny wydajności biomasy z 1 ha badanych gatunków podkładek po czopowaniu.

Production of nursery material in Podkarpackie Region in the last years has shown an increasing tendency and in 2012 amounted to over 3.8 million of fruit trees seedlings. The issue of waste biomass from agricultural and nursery production is significant since each time there is a need of waste disposal. Not in each case it is possible to carry out in the form of natural fertilizer. However, the use for energy purposes is always possible. The objective of the paper was energy analysis of waste biomass from production of different types of fruit trees. Laboratory tests concerning calorific value of particular species of stocks for production of fruit trees and on the content of ash and elements (C, H, N and S) in their chemical composition were carried out. Assessment of biomass yield from 1 ha of the investigated types of stocks after tenoning was carried out.

The potato (Solanum tuberosum L.) is one of the four major crops in Poland. In 2013 the area used for potato cultivation in Poland reached 270 thousand hectares. Among the important factors influencing the potato yield and quality are: soil cultivation and protection of plants. One of the most essential factors affecting the potato yield and quality is fertilization. The aim of the field trials carried out in 2014 on experimental potato plots was to determine the effect of dr Green foliar feed nutrients on plant health and on potato quality and yield (Jelly variety). The results of the studies and observations revealed that the application of Dr Green Ziemniak, Dr Green Start and Dr Green Energy foliar feeds favourably affected the quality, yield and structure of Jelly potato tuber crop.

Ziemniak (Solanum tuberosum L.) jest jedną z czterech najpopularniejszych roślin uprawnych w Polsce. Wielkość produkcji ziemniaka w 2013 roku w kraju wynosiła ponad 270 tysięcy hektarów. Istotnymi czynnikami kształtującymi wielkość i jakość plonów ziemniaka są między innymi uprawa roli i ochrona plantacji. Jednakże do najważniejszych czynników mających podstawowe znaczenie w kształtowaniu ilości i jakości uzyskiwanego plonu ziemniaka jest nawożenie. Celem przeprowadzonych w 2014 roku doświadczeń mikropoletkowych było określenie wpływu nawożenia dolistnego technologią Dr Green na zdrowotność roślin oraz na jakość i wielkość plonu ziemniaka odmiany Jelly. Uzyskane wyniki badań i przeprowadzonych obserwacji wykazały, że dolistna aplikacja nawozami Dr Green Ziemniak, Dr Green Start oraz Dr Green Energy korzystnie wpłynęła na jakość, wielkość i strukturę plonu bulw badanej odmiany ziemniaka.

The essence of the seed preparation process is the treatment of seed to protect plants against soil pathogens or seed-borne pathogens, as well as against pests attacking plants. Seed fertilizers are mineral fertilizers containing nutrients that, when applied to seed during seed preparation, become readily available to the developing root system during germination and initial plant growth. The purpose of this work was to evaluate the effect of Dr Green Prime seed fertilizer on energy and germination ability of wheat. Within the work wheat seeds in 5 variants were analysed, e.g., with the application of Dr Green Prime seed fertilizer, seed dressing A and fungicide A. The most kernels have germinated in the variant that has been treated with seed dressing A and Dr Green Prime. Only a small level of mould infestation or absence of the infestation was observed for seeds treated with seed dressing A. Aside from germination energy, ability and the level of infestation with moulds, the cotyledons and roots were weighed 12 days after the start experiment. The greatest mass of cotyledons and roots was observed for treatment with seed dressing A and Dr Green Prime 5.5 and 1.7 g, respectively.

Mechanical damage occurring during harvest, transportation or on various stages of processing of fruit and vegetables (in particular ground cucumbers) may lead to spoiling and disqualification of final products. Therefore investigations have been conducted to determine the cucumber’s resistance to mechanical damage and possible water loss in the raw material, as well as to enable the selection of best cucumber varieties suitable for processing. The goal of the conducted research was the determination of the impact of the cucumber variety, ozonation and the composition of the brine with the addition of probiotic bacteria on the mechanical properties and the microbial status of the final product. Mechanical properties were determined using a Zwick/ Roell Z010 machine and the data on the microorganisms were collected using Trypicase soy agar and MALDI TOF MS Biotyper. Other bacteria were detected using Man, Rogosa, and Sharpe agar media. The results indicate that a pre-ozonation or the addition of the probiotic both have a positive impact on the mechanical properties of the investigated product after the souring procedure. It was concluded the impact of both procedures on the puncture strength of final product was dependent on fruit variety.
