Abstract

An experiment entitled, “Studies on effect of herbal extract Samved Fugall (CO2) absorbent on Cotton.” cv. Bunny Bt BG II at Agricultural Research Station, Dharwad, Karnataka, India was carried out with objectives to study the effect of Samved Fugall on growth, yield and also to quantify the influence of foliar application of fugall on gas exchange and phenology in Bt cotton hybrid. The experiment comprised seven (7) treatments with three (3) replications laid out in Randomised Block Design. The results of experiment revealed that the treatment RD + foliar application of Samved Fugall @ 2ml/lit (60 and 90 DAS) recorded significantly high yield (1084 kg/ha) over control (824 kg/ha) and other treatments. In the same treatment the number of bolls/plant (18.30), plant height (48.20cm) and total number of leaves (40.90) were significantly higher than control and other treatments. In the same way days taken for 50% squaring, days taken to 50% flowering were significantly less in the same treatment than control. The same treatment showed significantly more no. of sympodia (13.80) than control RD (12.40). Foliar application of Samved Fugall @ 2ml/lit (60 and 90 DAS) recorded significantly more photosynthesis rate before spray (at 90 DAS) (18.23). The photosynthesis rate was highest after spray (at 110 DAS) (22.6). Untreated control recorded significantly least photosynthesis rate at all stages. Leaf area index, SPAD values (chlorophyll content) were also significantly more than untreated control.  

It appears from the results that foliar application of Samved Fugall @ 2ml/lit water at 60 and 90 DAS recorded significantly more yield. This has been supported from the physiological observations like rate of photosynthesis, leaf area index, total number of leaves, plant height and more number of sympodial branches including yield component viz. boll weight and number of bolls/plant.
