Description The present investigation entitled ?Studies on the effect of NAA, 4-CPA and boron on growth and yield of green chilli (Capsicum annuum L.) Var. Lam 353 in summer? was carried out during summer, 2013 at Horticultural College and Research Institute, Dr.Y.S.R. Horticultural University, Venkataramannagudem, West Godavari District, Andhra Pradesh. The studies were carried out with 16 different treatments involving two growth regulators (NAA and 4-CPA) and micronutrient boron individually and in combinations, at two different concentrations sprayed at 60, 90, 120, 150 and 180 DAS. The experiment was laid out in a randomized block design (RBD) with three replications and data on effect of different growth regulators and micronutrient boron on growth, yield and yield attributes were recorded and statistically analyzed.

With regard to growth characters, the plants sprayed with 20 ppm NAA + 0.05% boron (T9) recorded maximum plant height (83.33 cm), maximum plant spread (137.33 cm), maximum number of primary branches (17.0) and minimum number of days to 50% flowering (63 days) compared to other treatments.
With regard to yield attributes, the chilli plants sprayed with 20 ppm NAA + 0.05% boron (T9) also recorded the highest fruit set percentage (30.33%), maximum number of fruits per plant (124), fruit girth (2.98 cm) and mean fruit weight (2.24 g). It was followed by 20 ppm NAA (T2) in fruit set (28.33%), number of fruits per plant (121), fruit girth (2.92 cm) and mean fruit weight (2.17 g). However, the maximum fruit length was recorded in the plants sprayed with 20 ppm NAA (T2) with 8.43 cm, followed by 20 ppm NAA + 0.05% boron (T9) with 8.31cm.
The plants sprayed with 20 ppm NAA + 0.05% boron (T9) recorded highest number of seeds per fruit (66.73) and test weight (2.25 g). It was followed by (T2) 20 ppm NAA treatment (63.53 and 2.24 g respectively).
The highest green chilli yield per plant (263.5 g) with an estimated yield of 145.9 q/ ha was observed in the plants sprayed with 20 ppm NAA + 0.05% boron (T9). It was followed by the treatment 20 ppm NAA (T2) with 260.3 g/ plant and 141.69 q/ha respectively and were found on par with each other and significantly superior to control. While in the control, it was 128.4 g per plant with an estimated yield of 70.98 quintals per hectare.
Maximum amount of ascorbic acid (58.12 mg/100 g) was recorded with combination of 50 ppm 4CPA + 0.1% boron (T14), followed by 25ppm 4CPA + 0.05% boron (T11) with 57.56 mg/100 g.

The plants sprayed with growth regulators (NAA and 4CPA) and micronutrient boron either alone or in combinations recorded higher B : C ratios over the controls. The highest benefit : cost ratio (4.29) was obtained with combination of 20 ppm NAA + 0.05% boron (T9), followed by 20 ppm NAA (T2) with 4.21.
