EFFECT OF NAPHTHALEIC ACETIC ACID (NAA) ON GROWTH AND YIELD ATTRIBUTING CHARACTERISTICS OF CHILLI (CAPSICUM ANNUM L.) CV PUSA JWALA

Abstract

This study was conducted in field at Agricultural Research Farm, Mandhana, Rama University during February 2024 to May 2024 to study the effect of NAA on growth and yield attributing characteristics of chilli. There were 8 treatments and 3 replications laid out in Randomized Block Design. These were applied as basal application of fertilizer in this experiment. The treatment are T1, T2, T3,T4, T5, T6, T7, T8as control NAA@ 10 ppm, NAA@ 20 ppm, NAA@ 30 ppm, NAA@ 40 ppm, NAA@ 50 ppm, NAA@ 60 ppm NAA@ 70 ppm respectively. NAA at differentconcentrationswere applied exogenously tothe chilly cultivar Pusa Jwala. The plant height of plants was measured correctly and recorded in which the treatment of T7was highest at 120DAT (131.25 cm). Similarly, NAA T7treatment was maximum number of leaves per plants. The total number of leave were found highest in T7@ NAA 60 ppm was 9.52 and followed by T4, T5respectively. Likewise, maximum number of flower was also recorded in treatment T7that was 32.81. The size and weight of fruit was also gives the best performance at treatment T7. The yield per hectare was 32.56t/ha which was highest yield among other treatment. It revealed that application of different dose of NAA on chilly was found to be statistically significant.
