One of the factors of less soybean productivity of in Indonesia is caused by the N fixation. It can decrease the growth and the yield of soybean. One of the methods to overcome the N fixation is by rhizobium inoculation. The aim of this research was to observe the effects of rhizobium inoculation dosage and the number of seed per hole (population) to the growth and yield of soybean. The method used was Split Plot Randomized Completely Block Design (RCBD). The treatments were type of inoculant rhizobium dosage: without treatment, 3 and 6 g kg<sup>-1</sup> as well as the number of plants, 2 and 3 on planting pit. The result showed that the lowest plant height was in soybean without inoculated by rhizobium and 3 plants per planting pit. The lowest branches number was three plants per planting pit when compared than 2 plants on planting pit. Rhizobium inoculation was not significant to affect the number of leaves, number of branches, leaf area index, number of beans per pod, number of pods per plant, weight of 100 seeds, fresh weight, dry weight and yield.

The study was carried out to find out the effect of zinc (Zn) and boron (B) on growth and yield of okra (BARI Dherosh 1). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The treatments of the experiment were, T0 (without Zn or B), T1 (20 kg Zn ha-1), T2 (30 kg Zn ha-1), T3 (10 kg B ha-1), T4 (20 kg B ha-1), T5 (20 kg Zn ha-1 + 10 kg B ha-1), T6 (20 kg Zn ha-1 + 20 kg B ha-1), T7 (30 kg Zn ha-1 + 10 kg B ha-1) and T8 (30 kg Zn ha-1 + 20 kg B ha-1) were undertaken to evaluate the best results of the study. The highest plant height was found in T8 (30 kg Zn ha-1 + 20 kg B ha-1) but the highest number of leaves plant-1 was recorded from T7 (30 kg Zn ha-1 + 10 kg B ha-1). On the other hand, the maximum leaf area index, SPAD value, mean fruit weight, fruit length, fruit diameter, fruit dry matter (%), number of fruits plant-1, fresh fruit weight plant-1 , fruit yield plot-1 and fruit yield ha-1 were found in T7 (30 kg Zn ha-1 + 10 kg B ha-1), while the control (T0) showed lowest performance for the respected parameters. It is strongly concluded that 30 kg Zn ha-1 with 10 kg B ha-1 combination may be helpful for okra cultivation in the field level to increase okra production.

Aims: This study aimed to optimize the levels of gibberellic acid (GA3) and plant spacing on growth and yield of lettuce. Study Design: The experiment was laid out in Randomized Complete Block Design with three replications. Place and Duration of Study: Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka-1207, from November 2013 to January 2014. Methodology: The experiment consisted of two factors. Factor A- two levels of gibberellic acid (GA3,) application, viz. G1= 25 ppm and G2= 50 ppm in relation to a control G0 and factor B- four plant spacing viz. S1=15cm x 15cm, S2=20 cm x 20 cm, S3=25 cm x 25 cm and S4=30 cm x 30 cm. GA3 was applied twice as a foliar application by hand sprayer at 20 and 30 days after sowing. First, second and final harvesting was done at 25, 35 and 45 days after sowing respectively. Results: The growth and yield characters of lettuce showed significant variation for different levels of GA3 and plant spacing. Among GA3 levels, 25 ppm GA3 produced the maximum number of leaves (15.6), leaf area (283.9 cm2), fresh weight (91.6 g plant-1), dry weight (11.8 g plant-1), fresh yield (1794 g plot-1) and gross yield (12 t ha-1) at final harvesting compared to control where GA3 was not used. Under plant spacing, highest plant height (17.5 cm), leaf area (281.1 cm2), fresh weight (99.1 g plant-1) and dry weight (12.1 g plant-1) was revealed from wider spacing 30 cm x 30 cm followed by optimum spacing 25cm x 25cm. Meanwhile, closure spacing 15 cm x 15 cm showed maximum fresh yield (1710 g plant-1) and gross yield (15.5 t ha-1) due to higher plant density at final harvesting. Besides, lower chlorophyll content (0.43%) and the highest number of leaves (16.2) was found from 25 cm x 25 cm at final harvesting. So, optimum spacing 25 cm x 25 cm would be more suitable considering different points of view. Moreover, the treatment combinations 25 ppm GA3 with 25 cm x 25 cm exhibited highest benefit-cost ratio (2.04) than other treatments. Conclusions: It is concluded that the combinations 25 ppm GA3 application with 25cm x 25cm spacing would be optimum for better growth and yield of lettuce

Purpose: The aim of the study was to assess the effects of groundnut shell incorporation rates on the growth and yield of maize. Research methods: The study was carried out at the students’ demonstration farm of the Federal Polytechnic, Mubi, Adamawa State, in 2018. Seeds were sown on a prepared land treated with four (4) doses of groundnut shells (0, 25, 50 and 75 tons/ha) arranged in a randomized complete block design (RCBD), replicated 4 times. Each plot was marked out at 2.0 m length × 2.0 m width with 0.5 m gap between the replicated plots and blocks. Maize growth parameters were determined at 2, 4, 6 and 8 weeks after sowing and maize yield parameters were determined at 10 and 12 weeks after sowing (WAS). Findings: The groundnut shell application rates increased maize growth parameters such as, plant height, number of leaves per plant, leave area index, and stem girth, number of cobs per plant and cobs weight. The results revealed that plant height, number of leaves, leaf area index and stem girth were significantly (P≤ 0.05) influenced by the treatments, except for the control treatment at 2- WAS. The higher application rates (50 and 75 t/ha) of groundnut shell significantly (P≤ 0.05) influenced the plant growth components better than the 25 and 0 t/ha treatment rates. Research limitations: There were no limitations to report. Originality/Value: The results suggests that groundnut shell incorporation rate at 50 t/ha could be recommended as the most appropriate and profitable for high performance of maize plants in Mubi. The results generally suggest that maize plants may tolerate even higher rates of groundnut shell incorporation beyond the rates used in the study.
