Abstract

An experiment was conducted at research farm of Rajiv Gandhi South Campus, Barkachha, Mirzapur situated in eastern Uttar Pradesh during winter (rabi) season of 2021–22 with the objective to study the response of nitrogen, phosphorous, sulphur doses and urea foliar spray on lentil growth attributes, yield attributes, yield and economics under guava + lentil based agri-horti system. Results revealed that the higher growth, yield attributes, yield, net monetory returns and benefit-cost ratio were recorded under N_23.5+P₆₀+S₄₀ which was at par with N₂₀+P₅₀+S₃₀. In case of varied doses of foliar spray of urea, foliar spray of 2% urea at pre-flowering stage fb 2% urea at pod initiation stage recorded significantly higher growth, yield, yield attributes and economics which was at par with foliar spray of 2% urea spray at pre-flowering stage. Moreover, between the sowing of the lentils and the harvest, the guava's growth attributes were also increased. Therefore, under rainfed conditions of Vidhyan region of eastern Uttar Pradesh, application of nitrogen, phosphorus and sulphur @20, 50 and 30 kg/ha as basal application along with foliar application (spray) of 2% urea at pre-flowering stage (45 DAS) to lentil crop was found to be better option for higher profitability under guava plantation.
