Abstract
The field experiment on cotton productivity and leaf reddening as influenced by nutrition management for targeted yield was conducted during growing seasons of 2014-15 and 2015-16 at College of Agriculture Farm, Raichur, Karnataka on medium deep black soil under irrigation. Three yield targets (3, 4 and 5 t kapas yield ha-1) based site specific nutrient management (SSNM) along with four leaf reddening management (LRM) treatments (S1 - Vermicompost @ 2.5 t ha-1 in seed line, S2 - S1 + MgSO4 10 kg ha-1 in seed line, S3 - S1 + MgSO4 25 kg ha-1 in seed line, and S4 - MgSO4 25 kg ha-1 in seed line + foliar nutrition of 1% MgSO4 +19:19:19 + 1% KNO3 trice during flowering, boll development and boll bursting stages) besides recommended control were tested using RCBD. SSNM for 5 t ha-1 yield target and supplementary nutrition of MgSO4 both to soil and to foliage and foliar application of major nutrients (19:19:19 and KNO3) (S4) recorded significantly higher aphids count throughout (3.69, 5.42, 2.87 and 3.3), hopper count (10.7, 15.3, 17.5 and 13.1) and thrips count throughout (14.0, 17.8, 21.1 and 16.6 at 30, 45, 60 and 90 DAS, respectively on pooled basis). The dynamics population was lower with medium to lower yield targets; latter (M1) had lower count among all on pooled basis.
