Impact of foliar nutrition on morphological growth of mungbean (Vigna radiata) under guava (Psidium guajava) based agri-horti system

Abstract

A field experiment was carried out during the kharif season 2022 at Agroforestry Research farm, Rajiv Gandhi South Campus, Banaras Hindu University, Varanasi (Uttar Pradesh). The trial included 10 treatments, each reproduces three times in a Randomized Block Design. The study evaluated the effects of Recommended dose of fertilizers (RDF) N 18 P 48 K 24 , 2% neem coated urea, and foliar application of 4 ml L -1 nano urea, 0.5% zinc (ZnSO 4 ), and 0.2% boron, on Mungbean growth parameters during pre-flowering and pod development stages,. The data was recorded at 20 DAS, 40 DAS, and at harvest stage and revealed the outcomes with characteristics i.e., plant height (46.4 cm), number of branches (5.3), number of trifoliate leaves (6.9), number of root nodules (4.7), and dry matter accumulation (42.3 g) was highest in RDF + nano urea 4 ml L -1 + 0.5 % Zn + 0.2 % B twice at pre-flowering and pod development stage in treatment T 10 . Guava a 10 year old tree with an average height (5.85 m), canopy diameter (5.60m), stem girth (0.97 cm), and crown length (4.93 m). The study sought to determine how these foliar nutrients affect the overall growth and development of Mungbean plants under the specified conditions.
