Abstract

A field experiment was conducted during the Rabi season of 2015-16 and 2016-17 to study the effect of micronutrients and growth regulators on growth, physiology, yield, and quality attributes of chilli. Five levels each of different micronutrients (Control, 0.1% ZnSO4, 0.2% ZnSO4, 0.1% H3BO4 and 0.2% H3BO4) and growth regulators (Control, 0.5 ppm 28-Homobrassinolide, 1 ppm 28-Homobrasinolide, 10 ppm Putrescine, 20 ppm Putrescine) were used for foliar application to chilli plants. Simple correlation coefficient of different growth and physiological parameters, yield and quality attributes indicated that most of the morpho-physiological parameters of chilli viz., plant height, number of branches per plant, dry matter accumulation, LAI, CGR, RWC, chlorophyll a, chlorophyll b and total chlorophyll fruit length, fruit diameter, number of fruits per plant, number of seeds per fruit had significant positive content of leaves had significant correlation with fruit yield indicating their importance in yield determination. The result further revealed the quality parameters such as ascorbic acid content of fruit (mg/100g), capsaicin content (%), oleoresin content (%) of fruits were positively correlated with yield and yield attributes. Overall, it is logical to conclude that number of fruits per plant, CGR, total chlorophyll content, dry matter accumulation are the major contributors towards fruit yield since these characters had high correlation. The selection of these characters should be major concern for increased yield of chilli.

Conclusion

The morpho-physiological parameters, quality attributes and yield attributes of chilli were found to be significantly and positively correlated with fruit yield. Overall, as these traits showed strong correlation, it can be concluded that fruit yield of chilli is mostly influenced by the number of fruits per plant, CGR, total chlorophyll content, and dry matter accumulation. Selection of these traits with higher correlation should be a top priority for achieving higher fruit yield of chilli.
