Effect of integrated nutrient management on yield and economics of okra in an inceptisol

A:PS

Okra (cv. Parbhani Kranti) plants were treated with NPK (40:50:30 kg/ha) alone, NPK + micronutrients (MNS; soil application of FeSO4 at 50 kg/ha and ZnSO4 at 25 kg/ha, or foliar spraying of FeSO4 at 1.0% and ZnSO4 at 0.5%) or foliar and soil application of stranes microfood (SMF, 750 and 25 kg/ha, respectively), or NPK + micronutrients or stranes microfood + composted coir pith (CCP, 25 t/ha basal applications) and Azospirillum (2 kg/ha) in a field experiment conducted at Thekkupalayam, Coimbatore, Tamil Nadu, India [date not given]. Highest yields were recorded from NPK + SMF and MNS foliar treatments + CCP and Azospirillumand the lowest yield among the treated plants was recorded from the single NPK treatment (14.98 t/ha). The increase in yield over the single NPK treatment due to the addition of foliar sprays of SMF, MNS, and SMF and MNS with CCP and Azospirillum were 22.0, 20.0, 38.0 and 35.0%, respectively. Highest income (Rs. 20912/ha) and benefit cost ratio (11.3) was recorded from the foliar application of SMF + CCP + Azospirillum followed by foliar applications of MNS + CCP + Azospirillum (Rs. 18937/ha and 10.2, respectively).
