ANOWAR An experiment on the perfbrrnance of herbicide (Ronstar. Sencor and I.intur) on weed suppression towards growth and yield of wheat was conducted at the Agronomy Field, Shcr-e-Bangla Agricultural University, Dhaka-1207 during the period from November. 2007 to March. 2008. The experiment was laid out in a randomized complete block design having twelve combination treatments viz. (1) Ronstar 25EC Ø 1.0 I/ha. (ii) Ronstar 25 EC @ 1.5 I/ha. (iii) Ronstar 25EC @ 2.0 I/ha. (iv) Ronstar 25flC @ 2.5 I/ha. (v) Lintur 70W6 'd 0.20 kg /ha, (vi) l.intur 70WC1 0.25 kg /ha. (vii) l,intur 70WG @ 0.30 kg /ha, (viii) Lintur 70WG @ 0.35 kg Tha. (ix) Sencor 70WG 1; 0.30 kg/ha. (x) Sencor 70\VG @ 0.40 kg fha, (xi) Sencor 70W0 47 0.50 kg /ha. and (xii) Sencor 70WG ( 0.60 kg /ha, along with control (weedy) with three replications. Result showed that higher dry wcightiplant. 1000 seed weight, total grain yield, harvest index and benefit cost ratio (42.58g. 45.84g. 3.51 t!ha. 46.69% and 1.50 respectively) were obtained with Sencor 70WC1 (i. 0.50 Kg/ha treated crop. The highest plant height, number of tillers/plant. number of spikes/plant. spike length at harvest was also observed with the same treatment. In addition to those parameters. the lowest weed dry matter (19.38 kg/ha.) by Sencor 70WG d! 0.60 kg/ha. Sencor 70W6 (21? 0.50 kg/ha, showed the highest net return (23500.00 fl/ha). So. Sencor 70WG (2 0.500.60 kg/ha, could he considered as the recommended rate for controlling weeds in wheat field.

SHAMSUZZOHA The study was carried out at the research fleld of Sher-e- Bangla Agricultural University, Dhaka during 31 March 2007 to 8 June 2007 to evaluate the effect time of weeding and spacing on the yield perlbrmance of blackgram. The treatment comprised of three levels of weeding viz, no weeding, one weeding at 25 DAS and two weedings at 25 and 40 DAS. and four types ol spacings viz. 30cm x7 cm, 30cm x 10 cm, 30cm x 13 cm and 30cm x 16 cm. The experiment was laid out in a randomized complete block design factorial. Two times of weeding. (at 25 and 40 DAS) increased grain yield with higher values of harvest index as the crop characters like plant height, branches plant". number olleatlets plant", number of flowers plant", number of pods plant", seeds pod - dry weight plani', yield plant" and 1000 seed weight were higher. The seed yield with two weeding was 56.18% and 25.23% higher than no weeding and one weeding respectively. The spacing, 30cm x 10 cm showed its superiority by producing 7.96%, 8.92% and 16.19% higher yield than 30cm cm and 30cm xl6 eni spacing, respectively. The 30cm x x 7 cm. 30cm 10 cm spacing also showed higher biological yield and harvest index. Interaction of two weeding with 30cm xl 0 cm spacing performed best in respect of seed yield (1.58 t ha').

Sher-e-Bangla Agricultural University. Dhaka-1207 during the period from November. 2006 to March, 2007. The experiment was laid out in a randomized complete block design with three replications. Results showed that significantly higher yields of wheat (3.14. 2.92. 2.88 and 2.84 t hi', respectively) were obtained with the treatment of sole wheat, wheat 90% + lentil 10%. wheat 80% + lentil 20% and wheat 70% + lentil 30%. Signiticantly the highest combined yield of 3.21 t hi' was obtained with the treatment of wheat 70% + lentil 30%. The highest land equivalent ratio, benefit-cost ratio and total net return of 1.30, 2.14 and TIc 61026.75 hi'. respectively were obtained with the treatment of wheat 70% + lentil 30%. It was concluded that lentil may he intcrcroppcd with wheat using the combination of 70% wheat seed rate + 30% lentil seed rate.

AMAN RICE VARIETIES AS AFFECTED BY SEEDLING NUMBER HILL-1 AND UREA SUPERGRANULES MASUM, SHEIKH MUHAMMAD A field experiment was conducted at the experimental field of Sher-e-iIangla agricultural university during July to December 2007 to find out the effect of four levels of seedling hill4 vii; I. 13 and 4 and two forms of nitrogen fertilizer-prilled urea (PU) and urea supergranules (USC) on growth, yield and yield components of modem (BRRI Dhan 44) and traditional (Nizershail) transplant oman rice. The experiment was laid out in a split- split-plot design with three replications. Urea was top dressed 58 kg N haS ' in three equal splits at 10, 30 and 50 DAT. The USC (1.8 g) was placed at 5-10cm soil depth at 10 DAT in the center of four hills in alternate rows 1 granule in one spot to supply 58 kg N haS '. Results showed that rice varieties differed significantly in all growth characters and BRRI Dhan 44 produced higher grain yield (4.85 t ha'). Two seedlings hill' gave the highest grain yield (3.96 t hi') while four seedlings hill' had the highest numbers of total tiller hill', leaf area index and total dry matter. USC performed well in growth and gave higher grain yield (12.2%) over PU. Interaction results showed that significantly higher grain yields were given by transplanting one seedling of 13RRl Dhan 44 (5.38 t hi'), application of USC in I3RRI Dhan 44 (5.08 t hi') and transplanting one seedling hilr' with application USC (4.18 t had) and finally placement of USC by transplanting one seedling hill' of BRRI Dhan 44 (5.77 hi'). The higher grain yield was attributed mainly to the number of effective tillers bill', filled grains panicle' and 1000-grain weight.
