INFLUENCE OF SULPHUR AND BORON ON THE GROWTH AND SEED YIELD OF KASURI METHI (Trigonella corniculata L.)

Abstract

A field experiment was conducted at Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, during the Rabi season of October, 2020 to March, 2021 to study the effects of different level of sulphur and boron on the yield and yield components of Kasuri methi (Trigonella corniculata) seed. The experiment consisted of two factors: Factor A: Four Levels of sulphur (S); T 0 II = S 0 kg ha -1 , T 1 = S 10 = S 15 kg ha -1 , T 3 = S 20 kg ha -1 and Factor B: Four levels of boron (F); F 0

= B 1.0 kg ha -1 , F 2 = B 1.5 kg ha -1 , F 3 = B 2.0 kg ha -1 . The experiment was laid out in randomized complete block design (RCBD) with three (3) replications with total 16 no. of treatments. Data on different growth, yield contributing and yield parameter of kasuri methi were recorded and significant variation was observed from different treatments. In case of sulphur application, maximum plant height (48.17 cm), maximum number of primary branches plant -1 (9.51), secondary branches per plant (4.46), maximum number of seeds per pod (7.87), maximum number of pod per plant (1066.70), maximum weight of seeds per plant (2.33 g), maximum weight of seed per plot (69.84 g), maximum seed yield per hectare (582.03 kg), highest rate of germination (92%), were obtained from T 3 (S 20 kg ha -1 ) treatment. For boron application, maximum plant height (48.30 cm), maximum no. of primary branches per plant (9.46), secondary branches per plant (4.50), maximum number of seeds per pod (7.93), maximum number of pod per plant (1074.70), maximum weight of seeds per plant (2.34 g), maximum weight of seed per plot (70.15 g), maximum seed yield per hectare (584.62 kg), highest rate of germination (91.83%), obtained from F 3 kg ha -1 ) treatment. In case of combined application , T 3 F 3 treatment showed better performance over other treatment combination. Maximum plant height (50.08 cm), maximum number of primary branches per plant (10.41), secondary branches per plant (5.09), maximum number of seeds per pod (8.91), maximum number of pod per plant (1192.30), maximum weight of seeds per plant (2.50 g), maximum weight of seed per plot (75.00 g), maximum seed yield per hectare (625.00 kg), highest rate of germination (95.33%) obtained from T 3 F 3 treatment combination. It may be concluded that application of 20 kg S ha -1 with 2 kg B ha -1 was recorded to be more suitable practice for getting higher amount and quality of seed yield of kasuri methi.
