Influence of different agrochemicals on yield atributes & yield of chilli (Capsicum annuum L.) grown under hk region of Karnataka

Abstract

A field experiment was conducted at Agriculture college farm Raichur, University of Agricultural Sciences, Raichur, Karnataka to study the influence of different agrochemicals on morphological parameters and yield and yield components of chilli variety. The experiment was laid out in randomized complete block design with 3 replications during kharif season 2018. The experiment consisting of 9 different agrochemicals treatment along with a control i.e., T1: Gibberellic Acid (GA3) @10 ppm, T2: Naphthalene acetic acid (NAA) @10 ppm, T3: Methyl Jasmonates (Me JA) @ 0.5mM, T4: T2 + T3, T5: Cycocel @ 1000 ppm, T6: Nitrobenzene @ 10 ppm), T7: Brassinosteroides @ 0.15%, T8: T5+ T7, T9: Control. Among the treatments, NAA @ 10ppm recorded significantly higher number of fruits (146.33) over all other treatments followed by GA3 and Brassinosteroids (137.67 and 135.33). However, the treatments CCC, Nitrobenzene and combination of CCC and brassinosteriods (128.33, 106.00 and 106.67) did not differ significantly among themselves. Lowest yields (50.67) were recorded in control. However, the treatments GA3 and brassinosteriods and CCC were on par with each other. The treatment NAA @ 10ppm recorded significantly higher number of fruits (9.42 cm) followed by GA3 (9.13 cm) and Brassinosteriods (8.46 cm). However, the treatments CCC (8.41 cm), Nitrobenzene (8.18 cm) and combination of CCC and brassinosteriods (8.17 cm) did not differ significantly among themselves. The treatment NAA @ 10ppm recorded significantly higher yield (904 kg ha-1) over all other treatments followed by GA3 and Brassinosteriods 855 and 847 kg ha-1, respectively. However, the lowest yield (496.67 kg ha-1) was recorded in control.
