A field study conceded to assess the effect of pinching on growth and quality flowers yield of chrysanthemum at Horticulture Research Centre (HRC), Gazipur, Bangladesh. The research was laid out in Randomized Complete Block Design (RCBD) with six treatments and three replications. The treatment combinations were as T0- No pinching, T1- Once 40 days, T2- Once 50 days, T3- Once 60 days, T4- Twice 40 and 50 days and T5- Thrice 40, 50 and 60 days. It was observed that the highest plant height 60cm in no pinching (T0) and the lowest 45 cm was recorded by pinching the plants thrice (T5). Days of the first flowering (57 days) was observed where no pinching was followed and significantly delay in flowering (68 days) was recorded in in pinching the plants thrice (T5). The highest number of branches (12) was recorded in pinching the plants thrice (T5) and the lowest number of branches (05) in no pinching (T0). The maximum number of leaves (235) was recorded in pinching the plants thrice (T5) and minimum number of leaves (200) was observed in no pinching (T0). The treatment T5 (pinching the plants thrice) attained maximum plant spread (30 cm) and the treatment T0 (no pinching) attained minimum plant spread (17cm). The highest number of flower (45) was recorded in pinching the plants thrice (T5) treatment and the lowest flower (28) was observed in T0 treatment. Among the six treatment, T5 (pinching the plants thrice) showed the highest efficacy and it could be used as treatment in cultivation of Chrysanthemum indicum for growth and quality flower production.

A field study was conceded to assess the effect of plant growth regulators on growth and quality flower production of chrysanthemum at Horticulture Research Centre (HRC), Gazipur, Bangladesh. The experiment was laid out in Randomized Complete Block Design (RCBD) with ten (10) treatments and three replications. The treatments of plant growth regulators concentration were T1-50 ppm GA3, T2-100 ppm GA3, T3-150 ppm GA3, T4-400 ppm CCC, T5-600 ppm CCC, T6-800 ppm CCC, T7-250 ppm MH, T8-500 ppm MH, T9-750 ppm MH and, T10-Control. The maximum spreading of plant (27.0 cm) was observed when plants were treated with GA3 @ 150 ppm where the minimum plant spread (16.8 cm) was recorded in plants treated with CCC @ 800 ppm. The higher number of suckers (33) per pot was produced when pots were treated with GA3 @ 150 ppm whereas, application of CCC at three different concentrations produced lower number of suckers.  The highest number of flower (40) was recorded with 150 ppm GA3, where minimum number of flowers (25) per pot in 800 ppm CCC. The plants sprayed with 50 ppm GA3 took 48 days to flower initiation, whereas, it took 70 days with 750 ppm MH. the highest plants recorded (7.40 cm) with 800 ppm CCC, whereas, lowest size (6.50 cm) was obtained with the application of 500 ppm MH. The maximum vase life of flowers was recorded for the treatment 800 ppm CCC (15 days), which was at par with 13 days vase life obtained by spraying 600 ppm CCC. Therefore, it is concluded that the GA3 acted as growth promoter and the CCC acted as growth retardants on yield and quality of chrysanthemum.

Onion (Allium cepa L.) is one of the most important vegetables in family Alliaceae, which is cultivated worldwide. In onion, weeds are among one of the major concerns which cause its yield reduction. The present study was designed to assess the effectiveness of different methods for weed control in onion. In this study, five treatments were selected including control, black polythene mulch sheet, white polythene mulch sheet, Dual Gold spray @ 9.0 mL L-1 and Preact spray @ 7.5 mL L-1 to control weeds. The weedicides were applied as pre-emergence sprays before transplanting the seedlings. The experiment was laid out in Randomized Complete Block Design with three replications. From the results, it was concluded that there were significant differences among the studied weed control treatments. Among the five treatments, greater plant height (33.0 cm), number of leaves per plant (8), bulb diameter (4.7 cm) and bulb weight (73 g) were observed in the ridges covered with black mulch sheet. However, the minimum weed biomass (fresh and dry) was recorded in black mulch sheet and Preact pre-emergence weedicide spray (140 and 80 g in both). Thus, black polythene sheet as mulching material was found better option for weed management in onion fields.

Nine genotypes of castor oil bean (Ricinus cumunis) were evaluated in 2011 and 2012 cropping seasons to determine their consistency of performance at the Enugu State University of Science and Technology, Enugu State. Eight (8) accessions were selected from various locations in the south east, while a standard check was obtained from Ahmadu Bello University Zaria. The study was carried out using a randomized complete block design with four replications. Data was collected on number of days to germination, days to 50% flowering, plant height at maturity, length of primary raceme, length of pistillate region, length of staminate region and number of leaves. The findings from the study showed that Zaria accession flowers within 80 days and significantly (P < 0.05) different from the other eight (8) accessions studied, except Udi for plant height at maturity the significant and comparable large genotypes for all the characters except number of days to germination; number of nodes and length of staminate region implies that there would be adequate gains in selecting the characters. The phenotypic coefficient of variation was found to be higher than the genotypic coefficient of variance for all the character studied indicating the influence of environment towards the total variance. The short height recorded in Zaria and Udi accessions which are at par is of a desirable trait for shorter plants are easier to manage agronomical and it also withstands lodging better than all plants. These accessions based on the agronomic characters studied were found to perform very well in Enugu south-east, Nigeria and is therefore, recommended to be grown in this region.

Vegetative parameters of eight M3 (third mutant generation) lines of sesame were evaluated under rain fed condition. The seeds of the lines were sown alongside their respective controls using a randomized complete block design. The eight lines were generated from three parental stocks: NCRIBEN-04E (V1), NCRIBEN-01M (V2) and NCRIBEN-03L (V3). The three parental stocks were exposed to different doses of gamma irradiation from cobalt-60 source. 04E-550-G2-3 had the highest plant height (57.40) at the 6th week which was significantly different (P<0.05) from the three checks. 03L-450-G2-2 had the highest petiole length (12.45cm) which was significantly different (P<0.05) from the checks except check three (12.25cm) which was not significantly different (P>0.05). 03L-450-G1-2 had the highest number of leaves (91) and consequently highest number of branches (5.60). Although the number of leaves were significantly different (P<0.05) from Check three (54.60), there was no significant difference (P>0.05) between the number of branches and check three (5.40). The results obtained for vegetative parameters of M3 lines of sesame suggests that some of the genotypes could be used as potential parents for future breeding programmes aimed at improving sesame lines.
