Demonstration and Evaluation of Impact of Nitrogen Fertilizer on Growth and Yield Attributes of Okra (Abelmoschus esculentus L.) in Local Field Conditions of Dera Ghazi Khan

Abstract

A research trial was conducted at farmer’s field Mouza Kotla Shafi near Dera Ghazi Khan during kharif season 2020. Urea as a source of N applied at different doses (0, 40, 80, 120 and 160 kg ha^-1) using okra (Abelmoschus esculentus L.) as a test crop. The experiment was laid out in Randomized Completely Block Design (RCBD) with three replications under local field conditions. Urea was applied in split doses along with basal dose. Growth and yield were tributes such as plant height, number of fruits per plant, fruits fresh weight and fruit yield were determined. Application of N @ 160 Kg ha^-1 showed maximum improvement in growth and yield attributes compared to all other levels of N. Okra fruit fresh weight, yield and plant height showed maximum values of 15.31 g, 5915.4 Kg ha^-1 and 79.25 cm under N application @ 160 Kg ha^-1, respectively.
