INFLUENCE OF SALINITY ON YIELD AND SEED QUALITY OF CHILLI (Capsicum frutescens L.)

Abstract

The study was carried out at the Agronomy Net-house Sher-e-Bangla Agricultural University, (SAU), Dhaka-1207, during the period November 2016 to April 2017 to study the influence of salinity levels on yield attributes, yield and seed quality of three selected chilli varieties. For this purpose three varieties of chilli viz. Local, BARI Morich 1, BARI Morich 2 and 4 levels of salinity viz. 0 dS/m, 3 dS/m, 6 dS/m and 9 dS/m NaCl concentration were used. The experiment was conducted by following Completely Randomized Design (CRD) with three replications. Results showed that in terms variety BARI Morich 1 is the best variety than other two. BARI Morich 1 (V 2) showed the best result in plant height (27.16 cm), leaf number (28.75), pod length (6.63 cm), dry weight of plant (83.62 g), number of marketable fruit per plant (94 pieces on an average), weight of per green fruit (4.08 g), weight of per dry fruit (0.21 g), harvest index (18.46%), germination (54.50%), root length (4.44 cm), shoot length (5.38 cm), seedling length (10.32 cm) and dry weight of seedlings (0.30 g). In case of salt concentration application the best result was recorded in control (0 dS/m salt concentration). Results showed that in terms of salt concentration application of 0 dS/m salt concentration showed the highest plant height (29.11 cm), leaf number (29.88), pod length (6.44 cm), dry weight of plant (83.99 g), number of marketable fruit per plant (93.33 piece on an average), weight of per green fruit (4.54 g), weight of per dry fruit (0.24 g), harvest index (15.69%), seed germination (50.44%), root length (4.75cm), shoot length (5.69 cm), seedling length (10.40 cm) and dry weight of seedlings (0.29 g). The lowest result was found in case of S 3 (9 dS/m salt concentration). Considering interaction effect of variety and salinity V 2 S 0 was recorded for the best result in plant height (30.66 cm), leaf number (32.33), pod length (6.90 cm), number of marketable fruit per plant (101.33 piece on an average), dry weight of plant (87.35 g), weight of per green fruit (4.86 g), weight of per dry fruit (0.26g), harvest index (21.34%), seed germination (59%), root length (5.02 cm), shoot length (5.90 cm), seedling length (10.94 cm) and dry weight of seedlings (0.32 g). From the above result concludes that no chilli variety can perform better in saline condition.
