THE EFFECT OF BIOLOGICAL AND NANOFERTILIZERS ON COWPEA ( VIGNA UNGUICULATA L.) YIELD, QUANTITATIVE AND QUALITATIVE TREAITS IN THE SOUTHERN IRANIAN CLIMATE

Biological and nano fertilizers are alternative supplements to chemical security for the sustainability of agricultural production. This study is present investigate effect biological on quantitative qualitative yield cow pea during two crop years (2018-2019 2019-2020) in research farm South Agricultural Research Education Center Kerman province, Iran. experiment was carried out factorial designs randomized complete blocks with 16 treatments 3 repliation, studied factors include four levels (control, zinc amino chlate, aminoalexin, bio20) chelates boron chelate, potassium chelate iron chelate). The results showed that there no significant difference between terms all traits. While use nanochelates increased characteristics cowpea. In other words, lowest amount traits related cowpea absence chelate. Based obtained results, application bio20 fertilizer along or caused a increase general, according experiment, it found fertilizers, especially Bio20 Aminoalexin, improvement quality characteristics. positive aminoalexin improving significantly higher when used together chelates, which likely due various plant metabolic processes. It includes osmotic regulation, increasing chlorophyll, photosynthesis. Therefore, interaction biofertilizers (Bio20) (iron potassium) seed by 50% compared control (no use).
