Description |
A field experiment was conducted during Kharif 2010-11 at the Main Agriculture Research Station, University of Agricultural Sciences, Dharwad to study the effect of secondary treated distillery spentwash as source of nutrient in Bt cotton in Northern Transitional Zone of Karnataka. Results revealed that application of 150 kg N ha-1 through spentwash recorded significantly higher seed cotton yield (2566.1 kg ha-1) than RDF, 150 kg N ha-1 through fertilizers, RPP (RDF + FYM) and control. However former treatment was on par with the application of 100 kg N ha-1 through spentwash. The yield components, growth parameters and nutrient uptake followed similar trend. Significantly, lower micronaire value (3.73) was recorded with the application of 25 kg N ha-1 through spentwash + 75 kg N ha-1 through fertilizers and RPP (RDF + FYM), but was on par with all spentwash treatments. Other quality parameters did not differ significantly. Similarly, highest chlorophyll content (1.23 mg g-1 fresh weight) and lower Red Leaf Index (1.21) was recorded on 1st December with the application of 150 kg N ha-1 through spentwash than rest of the treatments followed by 100 kg N ha-1 through spentwash. Significantly highest jassid (4.20), thrips (28.90) and aphids (5.21) population were recorded with the application of 150 kg N ha-1 through fertilizers than the rest of the treatments. However, all application levels of spentwash was reduced the population of sucking insects. Similarly, significantly higher available soil nitrogen (272.7 kg ha-1) and potassium (966.7 kg ha-1) were recorded with the application of 150 kg N ha-1 through spentwash. However it was on par with the application of 100 kg N ha-1 through spentwash. Significantly highest EC (0.39 dS m-1) was recorded with 150 kg N ha-1 through spentwash. The study indicated that the application of 100 kg N ha-1 through spentwash was found to be suitable with respect to soil properties, yield, fibre quality parameters and higher net return ( 94,343 ha-1). |
