THE EFFECT OF UREA ON THE YIELD AND PROTEIN CONTENT OF TWO CULT!VARS OF MUNGREAN

Abstract

The experiment was conducted in the Farm of Sher-e-Bangla Agricultural University during the period from March to June 2010 to study the effect of urea on the yield and protein content of two cultivars of mungbean BARI mug-I and BARI mug-5. The two factors experiment was laid out in Randomized Complete Block Design (RCE3D) (factorial) with three replications. Data on different yield contributing characters and yield were recorded. At 20.30. 40. 50. 60 DAS and at harvest the taller plant (11.81 cm. 23.40 cm, 34.36 cm, 42.90 cm. 54.97cm and 61.33 cm) was recorded from BARI mug-S, whereas the shorter plant (10.69 cm. 21.26 cm.3 1.27 cm. 40.01 cm. 51.34 cm and 57.33 cm) from BARI mug-I. The higher seed yield (1.65 vita) was observed from BARI mug-S, whereas the lower seed yield (1.45 i/ha) from BARI mug-I. The higher stover yield (2.70 i/ha) 'as recorded from 13AR1 mug-S again the lower stover yield (2.24 t!ha) from BARI mug-I. The maximum protein (27.36%) was recorded for BARI mug-S than minimum protein of BARI mug-I (26.39%). At 20, 30, 40, 50, 60 DAS and harvest, the tallest plant (12.36 cm. 24.13 cm. 35.52 cm. 43.79 em. 56.35 cm and 62.64 cm) was observed from 30 kg N hi'. again the shortest (9.42 cm. 19.54 cm. 28.65 cm. 36.87 cm. 48.39 cm and 55.05 cm) from control (0 kg N ha1). The highest seed yield (1.73 i/ha) was obtained from 30 kg N hi'. again the lowest seed yield (1.24 i/ha) from control (0 kg N haSh. The highest stover yield (2.78 i/ha) was observed from 30 kg N hi'. while the lowest stover yield (2.03 i/ha) from control (0 kg N hi'). The maxitnuni protein content (27.521%) was found from 30 kg N hiS and the minimum protein content (25.49%) from control (0 kg N had). At 20. 30. 401, 50. 60 DAS and harvest the tallest plant (12.76 cm. 24.47 cm. 35.76 cm. 45.13 cm, 57.03 cm and 63.65 cm) was observed from BARI mug-S at 30 kg N ha1, while the shortest (7.41 cm. 17.63 cm. 23.10 cm, 31.77 cm. 42.96 cm and 50.30 cm) from BARI mug- I at control (0 kg N hi') condition. The highest seed yield (1.82 tiha) was recorded from BARI mug-S at 30 kg N hi' and the lowest seed yield (1.05 i/ha) from BARI mug- I at control (0 kg N ha1) condition. The highest stover yield (2.84 t/ha) was observed from BARI snug-S at 30 kg N hi'. whereas the lowest stover yield (1.36 i/ha) from BARI mug-i at control (0 kg N hi') condition. The maximum protein content (28.08°/s) was recorded from BARI mug-S at 30 kg N hi' and the minimum protein content (25.04%) from BARd mug-I at control (0 kg N hi') condition.
