Kenaf is a multi-purpose crop with numerous industrial uses. Its production is constrained by poor cultural and agronomic practices which reduce yield. Inappropriate spacing among others could result in low yield. Effect of plant spacing on growth and yield of kenaf was investigated in Ibadan, Nigeria. Kenaf seed was sown (2 plants/stand) at three plant spacing: 50×15, 50×20, 50×25 cm was assessed for seed and bast fibre yields using randomized complete block design (RCBD) with three replicates. The analysis was done using statistical analysis system (SAS). Plant spacing differed significantly for bast fibre and seed yields. Highest bast fibre yield (0.9±0.03) and seed yield (0.5±0.01) were obtained at 50×20 cm and 50×25 cm spacing, respectively, while the lowest bast fibre yield (0.7±0.01) and seed yield (0.3±0.01) were obtained at 50×15 cm spacing. Spacing of 50 × 15 cm and 50 × 20 cm are appropriate when planting for fibre while 50 × 25cm is appropriate for seed production. Keywords: Kenaf, Spacing, Fibre and Seed yield.

The use of Efficient Microorganisms (EM) can be an effective alternative to improve plant growth and yield in the bean cultivation. Therefore, different forms of application of efficient microorganisms were evaluated in the production of two cultivars of the common bean from November of 2013 to March of 2014. Two factors were studied; the first one was comprised of the two cultivars, Velazco Largo (VL) and Cuba Cueto (CC-25-9-N). The second factor consisted of four treatments with EM; without EM (control), soil inoculation (100 mL L-1), foliage applications (100 mL L-1), and the combined soil inoculation (100 mL L-1) plus foliar applications (100 mL L-1). The experiment was carried out in a randomized block design, in factorial outline 2×4, with three repetitions. The agronomic indicators were evaluated as the number of leaves per plant, the height of plants, number of pods per plant, number of seeds per pod, the mass of 100 seeds (g) and the yield (t ha-1). The results showed that the different forms of application of efficient microorganisms stimulated the agronomic indicators evaluated in both crops. The associated applications between the inoculation of the soil and foliage applications of efficient microorganisms provided better results, producing increments in the yield of 1.13 t ha-1 in VL and 2.15 t ha-1 in CC-25-9-N.

A research work was conducted with three sunflower genotypes to evaluate their performance in saline and non-saline soil after harvesting of T. Aman rice. The experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. Three genotypes significantly influenced almost all the growth and yield parameters in both non-saline and saline field. Genotype Hysun-33 showed maximum germination percentage in non-saline soil but minimum in saline soil. Whereas, KUSL- 1 performed the best in saline soil but worst in non-saline condition. Hysun-33 produced maximum leaf at flowering in both conditions but minimum leaf by BARI Sunflower-2 in saline soil and by KU-SL-1 in non-saline soil. In both non-saline and saline soils, plant height at flowering, head diameter, total seed head-1 and filled seed head-1 were maximum for the genotype Hysun-33 and that of minimum for the genotype BARI Sunflower-2. Genotype KU-SL-1 showed maximum value for 1000- seed weight followed by Hysun-33 in both saline and non-saline soils. In case of seed yield head-1, Hysun-33 performed best in saline soils but worst in non-saline soil. In non-saline soil, KU-SL-1 produced maximum seed yield head-1. Biomass at harvest, head diameter and number of filled seed head-1 was well correlated with number of seed head and seed yield head-1. Thus genotype Hysun-33 may be considered as best for saline and KU-SL-1 for non-saline soil. Bangladesh Agron. J. 2018, 21(1): 1-7

An investigation was carried out at the experimental field of the Department of Agronomy, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during September to November 2014 to evaluate the productivity of three mungbean genotypes, viz., GK-24 (G1), GK-63 (G2) and BU mug 4 (G3) under four plant spacing (densities) such as i) 15 cm x 10 cm= 66 plants m-2 (D1), ii) 20 cm x 10 cm= 50 plants m-2 (D2), iii) 25 cm x 10 cm= 40 plants m-2 (D3) and iv) 30 cm x 10 cm=33 plants m-2 (D4). The experiment was conducted in a factorial randomized complete block design with three replications. A wide variation among the genotypes was observed in relation to light transmission, yield, and yield contributing characters. At 30 cm x 10 cm spacing (D4) the highest light transmission ratio (LTR) was observed in G1 genotype (57.92) and the lowest LTR value in G2 genotype (46.92). Among the three genotypes, G1 produced the highest seed yield (1094 kg ha-1). But highest seed number pod-1 was found in D2 (11.61) while maximum pods plant-1 (11.08) was in D4 treatment followed by D3 (10.59). Among the four plant densities, treatment D3 showed the highest 1000-seed weight (50.30 g). The highest seed yield (1114 kg ha-1) was recorded in the treatment D4. Among the interaction, the highest number of seeds pod-1 (12.20) was found in the treatment D1G3, though the highest number of pods plant-1(12.03) was in treatment D4G1 but the1000-seed weight was the highest (51.92 g) in D3G1. The highest seed yield (1230 kg ha-1) was recorded from treatment D4G1. The result showed that GK 24 genotype performed the best in all respects of yield and yield attributes at 30 cm x 10 cm spacing compared to other treatments.Bangladesh Agron. J. 2016, 19(1): 11-17
