The effect of pig manure fermented by larvae of house flies on the yield parameters of sunflowers (Helianthus annus L.)

Abstract

The effect of fermented pig manure processed on a bed of wooden shavings and fermented for seven days by larvae of house flies on the yield parameters of sunflowers have been investigated on Haplic Luvisol in the pot trial realized in vegetative cage placed on the territory of SAU in Nitra. The experiment consisted of six treatments (0, NPK, Manure1, Manure2, Manure3, Veget). Treatments 0, NPK, and Veget were compared with the treatments Manure1, Manure2, and Manure3, i.e. with fermented manure applied at doses of 4, 6, and 8 t . ha−1.The results showed that application of fermented manure resulted in statistically significant greater stem thickness, higher leaf chlorophyll content, composites and harvest yield of seeds. The plants appeared healthy. Increasing the doses of fermented manure resulted in greater harvest yield of achenes and fat content in them. The dose of 4 t . ha−1 of fermented manure has proven to be insufficient.Out of the tested doses of 4, 6 and 8 t . ha−1 of fermented manure the highest achene yield has been achieved at the dose of 8 t . ha−1 but it was lower than the yield of the treatments fertilized by NPK fertilizers or Veget. From the viewpoint of achene yield quality (fat content) out of six variants the best parameters were achieved with the treatment where fermented manure at the dose of 8 t . ha−1 was applied.The gathered data point towards the applicability and usefulness of manure processed by larvae of flies in agronomy. It is of note, that the manure fermentation period can be significantly shortened, whereby reducing the storage difficulties.

The impact of vermicompost application on the yield parameters of maize (Zea mays L.) observed in selected phenological growth stages (BBCH-SCALE)

“…This is confirmed by the correlation coefficients between the thickness of the stalk and the plant heights measured in the individual phenological growth stages (Table 5). This find does not correspond with the knowledge of Kováčik et al (2010), who found Table 6, is obvious that the application of vermicompost, either alone or together with mineral fertilizer, had a significant influence on phytomass yield taken in growth stage BBCH 16 and on the total chlorophyll content (Chl a + b).…”

Role of Black Soldier Fly (<i>Hermetiaillucens)</i> Larvae Frass Bio-fertilizer on Vegetable Growth and Sustainable Farming in Sub-Saharan Africa

“…The frass application has positively impacted plant growth [55]. Focusing on frass quality in detail, concluded that frass nutrient levels should be high enough for a fertilizing effect, but there is still a lack of understanding of how frass practically affects soil fertility and plant growth [48].…”

Nutritional value of frass from black soldier fly larvae, Hermetia illucens, in a channel catfish, Ictalurus punctatus, diet

“…However, when compared to animal proteins, plant feedstuffs have lower protein content, unbalanced essential amino acid profiles, lower palatability, the presence of antinutrients (e.g. phytates, gossypol, tannins and lectin) and competition with other food‐feed industry sectors (Gatlin et al, ; Glencross, Booth, & Allan, ; Kováˇcik, Kozánek, Takáˇc, Galliková, & Varga, ).…”
