Effect of plant densities and Cycocel on leaf, chlorophyll content, yield and quality attributes of okra (Abelmoschus esculentus (L.) Moench) Cv. Parbhani Kranti

Abstract

An experiment was conducted at College of Horticulture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, during 2018 to know the effect of different plant densities (60 x 30 cm, 60 x 25 cm, 40 x 30 cm and 40 x 25 cm) and foliar application of cycocel (0, 400, 600 and 800 ppm) on various leaf, chlorophyll content, yield and quality attributes of okra. Experiment was laid in Factorial Randomized Block Design with three replications during summer season under shadenet house. The observations on leaf, chlorophyll content, yield and quality attributes were recorded during investigation. Results revealed that the significant effect of spacings on leaf area, chlorophyll-b, total chlorophyll, fruit yield per hectare and vitamin-C. Whereas, cycocel levels were found significant for the traits like leaf area, chlorophyll-b, fruit yield and vitamin-C. In case of interaction effects the characters like chlorophyll-b, total chlorophyll and fruit yield found significant performance. Remaining traits were not showned any significant influence under the experiment. The important characters like chlorophyll-b(84.06 mg-100g), total chlorophyll (173.17 mg-100g) were performed significantely maximum found better in spacing at 60 x 30 cm without the application of cycocel. However, these characters were at par with the spacing at 60 x 30 cm with the application of cycocel at 400 ppm. The highest fruit yield per hectare (16.13Mt) was noticed at spacing at 40 x 25 cm with the application of cycocel at 600 ppm. However, it was at par with the spacing at 40 x 25 cm with the foliar application of cycocel at 800 ppm. It is inferenced that the significantly highest fruit yield with maximum vitamin-C were found with planting density at 40 x 25 cm with the foliar application of cycocel at 600 ppm in okra at 30 and 45 DAS.
