GROWTH AND YIELD PERFORMANCE OF CRASSPEA UNDER DIFFERENT METHODS OF SOWING AND PRE-EMERGENCE IRRIGATION

Abstract

The experiment was conducted in the Fann ol' Sher-e-Bangla Agricultural University. Dhaka. Bangladesh during the period from December. 2007 to March 2008 to study the growth and yield performance of grasspea under different methods ci sowing and prc-emergenee irrigation. The variety BAR! Khesari-2 was used as the test crop. The treatments of the experiment were T,: Broadcast sowing without irrigation: 12: Furrow sowing without irrigation: T: Furrow sowing with furrow irrigation; T 4: Broadcast sowing with primed seeds: 'I' j : Furrow sowing with primed seeds: T 6 : Broadcast sowing with sprinkler irrigation at evening; 1 7 : Broadcast sowing with sprinkler irrigation at evening and morning: 'FR: Furrow sowing with sprinkler irrigation at morning and i's : Broadcast sowing with post sowing flood irrigation. Parameters were studied at 15. 25. 35. 45 and 55 days atler sowing. The highest seedling emergence (4.80. 19.65. 26.20. 54.20 and 71.50) was recorded in T 7 treatment whereas the lowest (2.40. 5.10. 18.20. 44.60 and 45.23) in T1 treatment. The tallest plant (15.11 cm. 34.91 cm. 42.79 cm. 59.41 cm and 71.92) at 15. 25, 35. 45 and 55 DAS was recorded in T 7 treatment and the shortest(l0.94 cm. 25.76 cm. 31.07 cm. 46.55 cm and 56.98 cm) in '1' treatment. The highest number of leaves, number of branches, number of flowers and dr v matter were recorded from T7

treatment and whereas, the lowest in T 1

treatment. 1'he highest pod number, pod length. number of seeds pod', weight of 1000 seeds were recorded from T7

treatment and the lowest in T 1

treatment. The highest seed yield (1.75 t ha 4 ) and stover yield (3.91 t ha 4 ) were recorded in T 7 treatment and the lowest seed yield (1.29 t hi') and stover yield (339 t hai in "I' s treatment.
