Moench) RP Patel, VL Purohit, HV Vasava, Tejal M Chaudhari and Pradip Sentha Abstract The experiment comprised of two factors varieties (GJO 3 and GO 6) and eight bio-stimulants treatment combination with total sixteen treatment combinations were laid out in Factorial Randomized Block Design (FRBD) with three replications. The results revealed that variety GO 6 (V2) found better in marketable fruit yield and bio-stimulants foliar application of Novel @ 1% and Panchagavya @ 3% just after initiation of flowering at 15 days interval and soil application of Jivamrut @ 500 l/ha (B8) at sowing onwards 30 days interval has been found effective with regard to growth parameters viz., plant height, number of primary branches, days to 50% flowering, number of flowering nodes and leaf area index; yield parameters viz., fruit length, number of fruits per plant, number of pickings, weight of fruit and marketable yield. Also, the net return and benefit cost ratio obtained higher in variety GO 6 and bio- stimulants Novel @ 1% + Panchagavya @ 3% + Jivamrut @ 500 l/ha. Keywords: Okra, bio-stimulants, panchagavya, jivamrut, novel, seaweed extract Introduction Okra (Abelmoschus esculentus L. Moench) is frequently known as Lady’s Finger or Bhendi, which belongs to family Malvaceae having chromosome number 2n=130 (Gadwal et al., 1968) [7] . The primary centre of its origin is believed to be the tropical or subtropical Africa. Besides being vegetable, it has also medicinal and industrial importance. It’s root and stem has been used for cleaning the cane juice in the manufacture of jaggery and sugar. Matured fruits and stem contain crude fiber are used in paper industry. Also, useful against genito-urinary disorders, spermatorrhoea and chronicdysentery. Novel prepared by fiber extraction of harvested banana pseudostem has good source of plant nutrients such as major and micronutrients along with growth promoting hormones like Cytokinin and Gibberellic Acid. Seaweed Extract contains major and micronutrients, amino acid, vitamins, cytokinin, auxin and abscisic acid like growth promoting substances. Panchagavya means the blend of five products obtained from cow namely dung, urine, milk, curd and ghee. Bio-chemical properties of panchagavya revealed that it possesses almost all the major nutrients like nitrogen, phosphorous, potash and micro nutrients essential for plant and growth hormones like IAA and GA required for crop growth (Selvaraj et al., 2007) [18] . Jivamrut contains small amount of major and micro nutrients but enormous amount of microbial load which multiply and enhance nitrogen fixation and nutrient mobilization and increase soil fertility. All bio-stimulants seems to have great potential to stimulate growth, improve yield and quality traits of crops. However very little information is available regarding these matters; therefor current study was conducted to investigate "Effect of bio- stimulants on growth, yield and quality of okra (Abelmoschus esculentus L. Moench)". Materials and Methods The present investigation was conducted at Educational Farm, Polytechnic in Horticulture, Junagadh Agricultural University, Junagadh during Kharif-2019. Total 16 treatment combinations comprised of two varieties viz., GJO 3 (V1), GO 6 (V2), four bio-stimulants alone viz., Novel @ 1% (B1), Seaweed extract @ 2.5% (B2), Panchagavya @ 3% (B3), Jivamrut @ 500 l/ha (B4) and in combinations viz., Novel @ 1% + Panchagavya @ 3% (B5), Seaweed extract @ 2.5% + Panchagavya @ 3% (B6), Panchagavya @ 3% + Jivamrut @ 500
