Biometric and physiological indicators of feed peas designed for green manure

Nikolai Dinev, Ivanka Mitova

Резюме: Using “green manure” is an alternative way to keep the soil in good conditions throughout the year. By using legumes, additional enrichment with available nitrogen compounds is achieved. The aim of the study is to establish the combined influence of soil and leaf fertilization on the development,
nutrient uptake and yield of forage peas. Indicators of economic importance have been measured to determine the suitability of the application - yield, nutrient content, nitrate content. It shows the relationship of climatic conditions with ontogenetic development. It has been established that the yields obtained are directly dependent on the fertilization applied. Plant nutrition with leaf fertilizers leads to the highest yield. Nitrogen and potassium content correlates with applied fertilizer rates, whereas phosphorous lacks differences between fertilization systems. The application of foliar fertilizers leads to a reduction of the nitrate content compared to soil fertilization. The data warranted the use of fodder peas as a sealing culture in sustainable farming system
