An experiment was conducted with a local cultivar of garlic to study the effects of planting date and gibberellic acid on the growth and yield of garlic at the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh during November 2001 to April 2002. Early planting influenced the plant height, leaf number, bulb diameter and total dry matter. With the delay in planting time starting from November 7, the yield was chronologically reduced in later plantings. Significantly the highest bulb yield (2.67 t/ha) was recorded when planting was done on November 7 and lowest yield (0.92 t/ha) was obtained from December 22 planted crop. Bulb yield was higher in control plants than those of GA3 treated plants. The interaction effects of planting date and different concentrations of GA3 differed significantly in respect of plant height, number of leaves, bulb diameter and dry weight of roots, leaves and bulbs and yield of garlic.

An experiment was carried out at the Horticulture Farm of the Bangladesh Agricultural University, Mymensingh during  the period from November 2010 to January 2011 to study the effects of cowdung and potassium on growth and yield  of Kohlrabi. The experiment consisted of three levels of cowdung (0, 20 and 40 t/ha) and four levels of potassium (0,  20, 50, 80 kg /ha). The experiment was laid out in randomized complete block design with three replications. All the  parameters were significantly influenced by application of cowdung and potassium. The highest plant height (44.65  cm), number of leaves per plant (12.11), length of largest leaf (37.54 cm), and breadth of largest leaf (18.66 cm) were  obtained from the highest dose of cowdung and potassium applied (40 t cowdung + 80 kg K/ha) while the lowest  plant height (33.64 cm), number of leaves (9.01), length of largest leaf (27.94 cm), and breadth of largest leaf (11.00  cm) were obtained from control treatment combination. The highest fresh weight of leaves (49.33 g), fresh weight of  knob (328.66 g) and fresh weight of roots (66.55 g) per plant were also recorded under the treatment combination of  40 t cowdung + 80 kg K/ha, while the lowest fresh weight of leaves (22.11 g), fresh weight of knob (136.00 g) and  fresh weight of roots (23.33 g) were obtained from control treatment combination. Similarly, the dry weight of leaves  (19.34%), knob (15.19%) and roots (32.75%) were highest under the same treatment combination of 40 t cowdung +  80 kg K/ha and the lowest dry weight of leaves (11.71%), dry weight of knob (7.38%) and dry weight of roots  (15.29%) were obtained from control treatment combination C0K0. The marketable yields of knob per plot (7.86 kg)  and per hectare (39.58 tons) were also the highest under the treatment combination 40 t cowdung/ha and 80 kg  potassium per hectare.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12035   J.

Growth and flowering of Zantedeschia elliottiana W. Wats. and Z. rehmannii Engl. were studied. Rhizomes of both species were produced either in a glasshouse or outdoors in California. Plants grown from glasshouse-produced rhizomes flowered within 90 days only when a preplant rhizome soak of 500 ppm GA, was applied. Control plants of both species flowered when grown from field-produced rhizomes, but a GA3 preplant rhizome soak significantly increased the number of flowers (spathe and spadix) produced. Paclobutrazol, applied as a preplant rhizome soak or as a soil drench when shoots were 2 to 3 cm long, significantly limited plant height of Z. rehmannii from either source if not treated with GA,. Paclobutrazol and GA, treatments interacted significantly to affect height and number of flowers of Z. rehmannii grown from field-produced rhizomes. Treatment with GA3 overcame the dwarfing effect of paclobutrazol, while paclobutrazol treatment limited flower production. Z. rehmannii rhizomes >6.5 cm in diameter produced more shoots and leaves than smaller rhizomes, regardless of GA3 treatment. Emergence, number of shoots, and number of leaves from Z. elliottiana were not significantly affected by the rhizome size-GA3 variable combination. Production of normal flowers was increased by GA3 treatment of all sizes of Z. rehmannii rhizomes except the smallest, with the most flowers being produced by plants from the largest rhizomes. Production of deformed flowers was greatest from rhizomes treated with 500 ppm GA3, with no deformed flowers on control plants.

Background: The low yield in groundnut which can be partly attributed to poor land preparation methods necessitated the need for alternative strategy of land preparation that will promote higher productivity in groundnut farming. Methods: A field experiment was carried out in two separate locations between May and August in 2016 to assess the effect of planting methods on growth and yield of groundnut cultivars. Result: The results revealed that groundnut crop sown on modified ridges and furrow with narrow furrow planting recorded significantly higher plant height, number of leaves, 50% flowering, yield attributes and yield when compared to other methods of planting All the groundnut cultivars responded positively to all planting methods except those grown on flat surface without beds. However, modified ridges and furrow with narrow furrow planting proved to be the best method.

A field experiment on coriander (Coriandrum sativum L.) was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during February 2009 to April 2009 to find out the optimum seed rate in relation to sowing methods for maximizing foliage yield of coriander. Four genotypes (CS001, CS002, CS003 and CS008) and three sowing methods (continuous line sowing spaced at 10 cm, 20 cm and broadcast method) and three levels of seed rate (30, 40 and 50 kg/ha) were used as treatment variables.. The result showed that genotype CS003 singly gave the maximum plant height, number of leaves/plant, single plant weight and plant weight/m2 and thus gave the highest foliage yield/ha. Line sowing (10 cm), broadcast method with seed rate @ 50 kg/ha independently produced the maximum foliage weight/m2 and foliage yield/ha. Line sowing (10 cm) with 50 kg/ha seed rate produced the highest foliage yield in case of CS001, CS002 and CS003 genotypes, which was closely followed by broadcast method and the same seed rate. But line sowing (10 cm) as well as broadcast method coupled with 40 kg/ha seed rate gave better foliage yield in genotype CS008. DOI: http://dx.doi.org/10.3329/bjar.v38i3.16970 Bangladesh J. Agril.
