Effect of Nanochitosan and Biocapsules on Growth, Yield and Quality of Red Okra (Abelmoschus esculentus L. ) Var. Kashi Lalima

Abstract

An experiment on okra was conducted throughout August to Nov 2021, in Horticulture Research Field, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, and Technology & Sciences Prayagraj (U.P) India. The results of the investigation, concerning the performance of Nanochitosan and Biocapsule within the 9 treatment of Red Okra i.e. t0 control (NPK): 100:50:50 Kg/ha, T1 Biocapsule 250 ppm, T2 Biocapsule 500 ppm, T3 Nanochitosan 50 ppm, T4 Nanochitosan 100 ppm, T5 Nanochitosan 50 ppm + Biocapsule 250 ppm, T6 Nanochitosan 50 ppm + Biocapsule 500 ppm, T7 Nanochitosan 100 ppm + Biocapsule 250 ppm, T8 Nanochitosan 100 ppm + Biocapsule 500 ppm. The seed was obtained from source of IIVR Varanasi. To find out the best performance in terms of growth, yield and quality the experiment was conducted in randomized block design, where each treatment replicated thrice. The results from the current investigation concluded that the treatment T6 (Nanochitosan 50ppm + Biocapsule 500 ppm) was recorded with maximum number of fruits (20.37 fruits/plant), with average fruit weight (14.22 gm), and also average fruit yield (143.13 q/ha) with Benefit cost ratio of 2.88 whereas in terms of quality the treatment T8 (Nanochitosan 100ppm and Biocapsule 500 ppm) was recorded with maximum TSS (3.94⁰Bx) and the treatment of T7 (Nanochitosan 100 ppm and Biocapsule 250 ppm) was recorded with maximum Ascorbic acid (21.38 mg/10 0g).
