Abstract

An experiment was Carried out at farmer’s field in Sivapuri village, Chidambaram taluk, Cuddalore district, Tamil Nadu during January-April, 2023 to examine the effects of fertilizer andorganic carbon source with foliar spray of nano zinc and seaweed extract on growth and yield of red bhendi (Kashi Lalima var VROR 157). Kashi Lalima is a red okra variety released by IIVR, Varanasi, in 2019. The fruits are reddish-purple in color and exhibits tolerance to yellow vein mosaic disease and okra leaf curl virus. Red-fruited okra has received much attention from consumers due to its appealing color and health-promoting constituents. The experiment was laid in randomized block design (RBD) with three replications. The treatments included,T1 - control, T₂ - 100 % RDF, T3 – 100 % RDF + nano zinc @ 0.1 % (3 times FS), T4 - 100 % RDF + SWE @ 2.5 % (3 times FS), T5 – 100 % RDF + OCS @ 2.5 t ha-1, T6 - 100 % RDF + OCS @ 5.0 t ha-1, T7 - 100 % RDF + OCS@ 2.5 t ha-1+ nano zinc @ 0.1 % (3 times FS), T8 - 100 % RDF + OCS @ 5.0 t ha-1 + nano zinc @ 0.1 % (3 times FS), T9 - 100 % RDF + OCS @ 2.5 t ha-1 + SWE @ 2.5 % (3 times FS), T10 - 100 % RDF + OCS @ 5.0 t ha-1 + SWE @ 2.5 % (3 times FS). The result showed that treatment T8 - 100 % RDF + OCS @ 5.0 t ha-1 + nano zinc @ 0.1 % (3 times FS) was the most effective exhibiting better growth, yield, yield attributes and quality characters.
