Agricultural activities play a vital role in providing essential human sustenance, yet concurrently generate biomass waste, necessitating careful management to prevent environmental pollution. This study emphasizes the significance of proper agricultural waste management to prevent the underutilization of livestock excrement and the indiscriminate burning of crop residues, thereby ensuring food and health security, as well as sustainability in agriculture. The decomposability of agricultural wastes offers an opportunity to harness valuable products that furnish essential nutrients for plants, enhancing soil porosity, aeration, and water availability. Oyster mushroom baglog (OMB) containing wood sawdust, rice husks, and bran presents an environmental challenge when improperly handled in post-cultivation. This mismanagement can lead to pollution and unpleasant odours, and attract pests and diseases. This research explores the potential of composting OMB, incorporating animal manure, to produce composted materials suitable as a growth medium for crops. The study investigates four different compost compositions derived from OMB, evaluating their effectiveness in cultivating sweet corn (Zea mays sacharata Sturt) with a focus on determining the composition that yields optimal results for the Bonanza F1 variety. Four distinct treatments were examined: OMB without added animal manure (Ko), OMB with chicken manure (Ka), OMB with cow manure (Ks), and OMB with goat manure (Kk). The treatment involving the addition of chicken manure (Ka) to the OMB demonstrated superior effectiveness in terms of both vegetative growth and sweet corn yield. This study provides valuable insights into sustainable agricultural practices, highlighting the potential of composted materials from oyster mushroom waste to enhance sweet corn cultivation.

The authors determined the accuracy and reliability of yielding models by using the values of two differently obtained indices – the leaf area index (LAI) obtained through direct surface measurements, and the normalized difference vegetation index (NDVI) obtained through spatial remote sensing of crops. The study based on the drip-irrigated sweet corn yielded the data obtained in the field experiment held in the semi-arid climate on darkchestnut soil in the South of Ukraine. The suitability of the LAI and NDVI for the simulation of sweet corn yields was estimated by the regression analysis of the yielding data by correlation (R) and determination (R2) coefficients. Additionally, mathematical models for the crop yields estimation based on the regression analysis were developed. It was determined that LAI is a more suitable index for the crop yield prediction: the R2 value was 0.92 and 0.94 against 0.85 for the NDVI-based models.I It was determined that it is better to use the LAI values obtained at the stage of flowering, when R2 averaged to 0.94, and the NDVI-based models does not depend on the crop stage (the R2 was 0.85 both for the flowering and ripening stages of the plant development). The combined NDVI-LAI model showed that there is no necessity in the complication of the LAI-based model through introduction of the remotely sensed index because of insignificant improvement in the performance (R2 was 0.94 and 0.92).

W pracy oceniano dynamikę zmian średniej zawartości cukru w ziarnie kukurydzy cukrowej w zależności od terminu zbioru. Badania przeprowadzono dla trzech odmian kukurydzy cukrowej (Bonus, Boston, Jubilee). Dynamikę zmian średniej zawartości cukru analizowano na podstawie oszacowanych funkcji regresji. Z uwagi na to, że pomiary uzyskane dla poszczególnych terminów zbioru kukurydzy nie spełniały założeń wymaganych w zwykłej regresji, do wyznaczenia i porównania zależności regresyjnych wykorzystano wielozmienną metodę krzywych wzrostu wskazując odmianę najbardziej pożądaną z punktu widzenia konsumenta.

The paper contains the evaluation of the dynamics of changes in average sugar content in grain corn, depending on harvest date. The research was carried out for three cultivars of grain corn (Bonus, Boston, Jubilee). The dynamics of changes in average sugar content in grain corn has been analysed on the basis of estimated regression functions. Due to the fact that the measurements obtained for each harvest date did not meet the assumptions required for ordinary regression, the multivariate growth curves method was used to determine and compare regression dependences, showing the most desirable corn variety from consumer's point of view.

W przeprowadzonym eksperymencie zaobserwowano wzrost stopnia odziarnienia i udziału ziarna całego oraz spadek ziarna uszkodzonego i pozostałością rdzenia wraz z opóźnianiem terminu zbioru kolb. Badania wykazały, że pozyskiwanie ziarna kukurydzy cukrowej na cele konsumpcyjne metodą omłotu, po uprzednim jego zmrożeniu, jest możliwe zarówno dla kolb zbieranych w terminach o wyższej jak i o niższej wilgotności ziarna.

Completed experiment allowed to observe increasing degraining level and share of whole grain, and decreasing share of damaged grain and core residue with cob harvest being delayed. The research has proved that acquiring sweet corn grain for food production purposes using threshing method, after having frozen it, is possible for cobs gathered according to the schedule and characterised both by higher and lower grain humidity.

W badaniach przyjęto trzy warianty nawożenia oraz cztery poziomy stosowania dawek azotu (O - obiekt kontrolny, 60, 90 i 120 kg N/ha). Określano wielkość plonu kolb kukurydzy cukrowej dla trzech supersłodkich odmian, tj. Golda, Candle i Helena, w zależności od wielkości dawki azotu i sposobu jego aplikacji. Badano także wpływ nawożenia azotem na zawartość sacharozy w ziarnie kukurydzy cukrowej dla przyjętych odmian. Stwierdzono znaczne zróżnicowanie zarówno wielkości plonu kolb, jak i zawartości sacharozy w ziarnie kukurydzy cukrowej, w zależności od dawki azotu i sposobu jego stosowania dla poszczególnych odmian kukurydzy.

The investigations focused on analysis of nitrogen fertilization impact on both corn ear crop and quality characters of sweet corn. There were assumed three variants of fertilization measures and four levels of nitrogen rates (0 - control level; 60; 90 and 120 kg N/ha). The sweet corn ear crop was determined for three super-sweet varieties: Golda, Candle and Helena, according to nitrogen rate and method of application. There was also assessed nitrogen fertilization impact on sucrose content of the sweet corn varieties under study. Significant differences were discovered as regards both - ear corn crop and sucrose content in sweet corn conditioned by nitrogen rate and method of application used for respective corn variety.

Badania wpływu wybranych parametrów pracy obcinarki na proces cięcia ziarna kukurydzy cukrowej określano na stanowisku badawczym. Pomiary prowadzono przy prędkości obrotowej głowicy nożowej w zakresie 1600 do 2560 obr*min-1 i zmiennej średnicy rozstawu noży tnących w granicach 25 do 35 mm. Prędkość podajnika kolb była stała i wynosiła 0,31 m*s-1. Analiza statystyczna uzyskanych wyników badań wykazała, że zmiana prędkości obrotowej głowicy tnącej oraz średnicy rozstawu noży wpłynęły istotnie na wzrost jakości procesu odcinania ziarna oraz zmniejszenie współczynnika nierównomierności cięcia.

The investigations of influence of chosen parameters of cutter work on process of cut of sweet corn kernels were defined on investigative stand. The measurements were led near rotational speed of knife head in range 1600 to 2560 obr*min-1 and the variable of diameter of span knives cutting in interval 25 to 35 mm. The speed of feeder of cobs was solid and carried out 0,31 m*s-1. Statistical analysis of got results of investigations shew that they had influenced the change of rotational speed of cutter head as well as diameter span knives on growth of quality of process indeed the parting the grain as well as decrease the coefficient of inequality of cut.
