Effect of organic nutrients on morphological, yield attributes of okra under southern eastern Rajasthan

Abstract

A field experiment was conducted during Kharif seasons of 2022 and 2023 at Organic Block, Agricultural Research Station, Ummedganj, Kota, Rajasthan, to assess effect of various liquid organic nutrients sources on growth, yield and economic feasibility of okra. The experiment was layout in randomized block design with 3 replications, comprised 10 treatments: (T0) Control, (T1) Vermiwash spray (10%) at 30, 45 and 60 DAS, (T2) Jeevamrut (500 litres/ha) at sowing and 30, 45, and 60 DAS, (T3) Cowurine spray (10%) at 30, 45, and 60 DAS, (T4) Panchgavya spray (5%) at 30, 45, and 60 DAS, (T5) Amritpaani (500 litres/ha) at sowing and 30, 45, and 60 DAS. The results of two-years revealed that the combined application of Jeevamrut 500 litres/ha at sowing +Amritpaani at 500 litres/ha at sowing, Panchgavya (5%) and Vermiwash (10%) at 30, 45, and 60 DAS significantly increased the number of fruits per plant and number of flowers compared as to control. This treatment also shortened the days to first flowering and expanded the leaf area relative to the control. Yield per plant and hectare was also higher, respectively both years and pooled analysis. Gross return and net returns was also gained. Hence, in this findings suggest that the integrated use of liquid organic manures with FYM can be an effective organic option to enhance growth and yield of okra.
