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.

Abstract Plant growth is influenced by seed quality. Seeds need to be treated to prevent pest and disease disorders or to increase seed germination. Soybean planting was carried out in this study by the treatment of varieties and seed pre-treatment application before planting. The study aimed to measure the growth and yield of soybeans by varieties and seed treatment before planting, carried out in the Village of Nggembe, District of Bolo, Bima Regency. The study used factorial randomized block design with two factors. The first factor was soybean varieties consisting of two levels, namely Devon and Dena varieties, and the second factor was the application of pre-planting seed treatments consisting of four levels namely Cruiser, Marshall, Agrisoy, and without seed treatment, each treatment was repeated three times. Observations were made on the performance of agronomic crops and soybean yields. The results showed that the treatment of soybean varieties and the application of seed treatment had a significant influence on plant height and soybean productivity, and both treatments had interactions on parameters of plant height, number of filled pods, weight of 100 seeds, and soybean productivity with the best results successively produced by a combination of Devon-Control, Devon-Marshall, Devon-Agrisoy, and Dena-Cruiser.

Indigofera Tinctoria

<p class="Default"><em>Indigofera tinctoria</em> is a legume that is cultivated as a source of natural indigo dyes. As a legume, <em>Indigofera tinctoria</em> is capable of symbiosis with soil microbes. This study evaluates the effects of light intensity and microbial inoculation on root growth and nodulation. The study used a complete randomized block design with a split-plot pattern. Light intensity was the main plot with four levels of light intensity 100%, 50%, 25%, and 10%. Microbial inoculation was a subplot with four levels without inoculation, mycorrhizae inoculation, rhizobium inoculation, and double inoculation with both mycorrhizae and rhizobium. The results obtained show that light intensity and microbial inoculation affected root length, root fresh weight, root biomass, and the number of nodules. 50% light intensity was optimum for root length, while 100% light intensity was optimum for root fresh weight, root biomass, and a number of nodules. Root growth and nodulation were further increased with double inoculation. The combination of light intensity and microbial inoculation affected root biomass and nodulation. The combination of 100% light intensity and double inoculation resulted in the highest root biomass and nodule numbers. Mycorrhizae and rhizobium have a synergistic relationship to nodulation and root growth. Double inoculation with mycorrhizae and rhizobium efficiently increased root biomass and the number of nodules under low or high light intensity.</p>

A field experiment was conducted during the Rabi season 2017–2018 (October–March) at the University of Agriculture, Peshawar research farm to examine the influence of different nitrogen (N) and phosphorus (P) levels on two different oat varieties: Australian and Ukrainian. The treatments included control and three levels of nitrogen and phosphorus at 30, 60, and 90 kg ha−1. The treatments were arranged in randomized complete block design (RCBD) and replicated three times. The findings showed that the oat varieties were significantly different from one another in yield and yield parameters. The Australian variety recorded higher emergence (49 plants m−2), days to emergence (15 days), days to flowering (122 days), days to maturity (145 days), plant height (142.7 cm), number of leaves (6.03 leaves plant−1), number of tillers (92.2 tillers m−1), biological yield (8,179.2 kg ha−1), and grain yield (3,725.6 kg ha−1) than the Ukrainian variety. Similarly, different N and P levels, the maximum days to emergence, days to flowering, and days to maturity were recorded in a control plot. The application of 105 kg N + 90 kg P ha−1 was statistically similar to the application of 105 kg N + 60 kg P ha−1. Maximum emergence (60 plants m−2), number of leaves (7.0 leaves plant−1), plant height (118.6 cm), number of tillers m−1 (102.6), biological yield (9,687.5 kg ha−1), and grain yield (4,416.7 kg ha−1) were determined in Australian variety. Based on the findings of this study, the Australian variety performed better in terms of yield and yield components and the application of N and P fertilizers at the rate of 105 kg N + 60 kg P ha−1 produced the best results in both oat varieties.

To evaluate the effect of Zinc fertilizer on performance of wheat cv. BARI gom30, an experiment was carried out at Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, from November 2015 to March 2016. The experiment comprised four levels of Zinc (Zn) viz., 0, 1.5, 2 and 2.5 kg/ha. The experiment was laid out in a randomized complete block design with three replications. Application of Zinc (Zn) plant height, number of total tillers/plant, number of effective tillers/plant, spike length, number of fertile spikelets/spike numbers of sterile spikelets/spike number of grains/ spike, grain yield and straw yield were found significant. But there was no significant effect of the treatment on 1000-grain weight. The highest number of total tiller/plant (4.42), number of effective tillers/plant (3.92), number of grains/spike (47.70), 1000-grain weight (47.73 g), grain yield (5.06 t/ha), straw yield (6.21 t/ha) was obtained from 2 kg Zn/ha. The highest plant height (94.08 cm), spike length (9.92 cm), number of fertile spikelets/spike (19.59) and sterile spikelets/spike (3.22) and harvest index (46.16%) were recorded at 0 kg Zn/ha respectively. The control treatment indicated the lowest value for the yield attributing characters except the number of sterile spikelets/spike. Grain yield was found to be significantly and positively correlated with number of grains/spike and straw yield. It is recommended that application of 2 kg Zn/ha is the best for maximum yield of BARI gom30.

Caladium × hortulanum Birdsey `Candidum' tubers were forced in pots until at least one-half the visible sprouts were 2 cm above the soil surface. These prefinished plants were subjected to simulated transit durations of 2, 4, or 6 days in the dark at 12.5, 15.5, 18.5, 21.0 or 24C. Plants were then grown for 4 weeks in a greenhouse and were either fertilized weekly with 100 ml of a solution containing 500 N-218P-415K (mg·liter-1) or were not fertilized. Interactive effects between transit duration and temperature were significant for all measured growth responses. Transit temperature maintained for 2 days had little effect on subsequent growth and only moderate effects after 4 days. With transit duration of 6 days, an increase in temperature resulted in increased plant height, fresh weight, number of leaves, white coloration of leaves, and percent of plants judged marketable (finished) in 4 weeks. Holding at ≈ 18.5C was most favorable for transit durations of 4 or 6 days. Use of fertilizer during finishing improved plant growth regardless of transit conditions, but did not totally negate deleterious effects from transit conditions.
