EVALUATION OF BIO-EFFICACY STUDIES OF PLANTBIOTI X PRODUCT “INCRYL ULTRA” ON OKRA (ABELMOSCHUS ESCULENTUS (L.) MOENCH) CULTIVATIONArchit Sharma, Deven Verma, Jassasvi Prashar and Taranpreet KaurAbstract The field experiment was carried out during summer season of 2023 at the Agriculture Research Farm, School of Agriculture, Lovely Professional University, Phagwara (Punjab). The experiment was planned using RBD with five treatments which were T1: control (RDF), T2: Incryl Ultra @ 0.5g/l + RDF, T3: Incryl Ultra @ 1.0g/l + RDF, T4: Incryl Ultra @ 2.0g/l + RDF and T5: Standard check product (IFFCO Sea Secret) and five replications. Results revealed that the treatment T4 gave maximum results in traits like germination percentage (83.50%), seedling dry weight (0.95 g), seedling fresh weight (2.85 g) and seedling vigor index II (79.38) while in T5 seedling vigor index I (1596.76) were highest. Parameters like plant height (55.90 cm), number of leaves per plant (29.90), number of branches per plant (3.40), leaf area (409 cm2) and leaf chlorophyll content were maximum in T4 (60.21 SPAD meter reading). Traits related to flowering like days to first flowering was least in T2 (45.45) and days to 50% flowering was least in T4 (47.80). The number of flowersper plant was also highest in T4 (19.85). The number of fruits per plant and average fruit weight were also maximum in T4 (18.42) and (16.77g) respectively. Maximum yield, i.e., 10.30 ton/ha was observed in T4. T4 gave also maximum TSS content (2.51 oBrix) while T5 gave maximum ascorbic acid (21.10 mg/100 g) and mucilage content (13.85%) in okra. The least crude fiber content (7.04%) was found in T5 and physiological loss in weight (8.68%) after harvesting was also observed in T4. Best net returns (2,28,781.43/ha) were found in T4 and best B:C ratio (2.84) was observed under T4. |
