RESPONSE OF PECHAY (Brassica rapa L.) TO DIFFERENT SOURCES OF ORIENTAL HERBAL NUTRIENT (OHN) FORMULATIONS AGAINST CABBAGE WEBWORM (Crocidolomia pavonana, Fab.)

This experiment was conducted to evaluate the response of Pechay (Brassica rapa L.) to different sources of Oriental Herbal Nutrient (OHN) formulations against Cabbage Webworm (Crocidolomia pavonana, Fab.) from February 2019 to April 2019. This experiment was carried out using Randomized Complete Block Design (RCBD) with five treatments and three replications. The treatments were as follows: Ti - Control (Base OHN - garlic + onion + ginger); T2 - (Base OHN - garlic + onion + ginger) + chili; T3 - (Base OHN - garlic + onion + ginger) + neem leaves; T4 - (Base OHN - garlic + onion + ginger) + turmeric; T5 - (Base OHN - garlic + onion + ginger) + chili + neem leaves + turmeric. The results of the study revealed significant effects of the foliar application of different Oriental Herbal Nutrients (OHN) formulations on plant height, length of petioles, plant weight, weight of marketable plants, weight of non-marketable plants and plant yield of pechay. The foliar application of Oriental Herbal Nutrients (OHN) formulations against cabbage webworms was found to be effective at 43%. Therefore, it is recommended to use T4 - (Base OHN - garlic + onion + ginger) + turmeric as an organic pesticide on pechay and can be tested on other vegetable crops.
