This study aims to compare the effects of different laser wavelengths, exposure times, and low-power-intensity laser irradiation on maize seeds. Seeds were exposed to He–Ne (632.8 nm) red laser, Nd:YAG second-harmonic-generation (532 nm) green laser, and diode (410 nm) blue laser. Four different exposure times (45, 65, 85, and 105 s) with different intensity (2 and 4 mW/cm2), for each laser were tested. Phenology and yield components (plant height, leaf area, number of rows per ear, seed yield, harvest index, yield efficiency, and grain weight) were determined. The experiment was conducted in a randomized complete block design with three replications. Plant height was found comparatively high in blue laser light—211 cm at 85 s. Blue and green laser lights showed significant increases in the number of rows per ear to 39.1 at 85 s and 45 at 65 s, respectively, compared to the control of 36 rows/ear. The order of seed yield was blue (7003.4 kg/ha) > green (6667.8 kg/ha) > red (6568.01 t/ha) based on different exposure times of 85 s, 85 s, and 105 s, respectively, compared to the control of 6.9 kg/ha. The findings indicate the possibility of using blue laser light to manipulate the growth and yield of maize.

Background and Objective: Sulphur and boron are found as most critical nutrient elements for the better growth and yield of mustard crop however no such concrete information for their uses in field production of this crop is yet to be reported. Therefore, an experiment was conducted to investigate the effect of agronomic biofortification of sulphur and boron nutrients on the growth and yield of mustard crop. Study Design: The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replicates. Place of Study: The experiment was carried out in the Crop Botany Field Laboratory, Bangladesh Agricultural University, Mymensingh. Methodology: Three doses of sulphur (S) viz. 0, 20 and 40 kg ha-1 and three doses of boron (B) viz. 0, 0.5 and 1.0 kg ha-1 and their possible combinations were used as basal doses. Field data were collected from periodic destructive samplings on the plant height, number of leaves and branches per plant, total dry matter accumulation and finally yield components and yield. Results: Sulphur and boron fertilizations significantly influence the plant height, production of branches and leaves per plant, dry matter accumulation and yield attributes and yield of mustard crop. The mustard crop fertilized with 40 kg S ha-1 in combination with 1 B kg ha-1 produced taller plant, higher number of branches and leaves in each plant and higher amount of dry matter per plant while these plant traits were found as minimum when the growing the mustard crops in control plots i.e. the plants received neither sulphur nor boron. Application of sulphur @ 40 kg ha-1 along with boron @ 1 kg ha-1 produced the highest seed yield (2.73 t ha-1) whereas the lowest seed yield (1.08 t ha-1) was found where no sulphur and boron were applied. Conclusion: The result conclude that combine application of sulphur and boron @ 40 and 1 kg per hectare, respectively was found to be most effective dose in enhancing growth and yield of mustard crop.

Abstract The efficiency of a breeding program depends mainly on the direction of the correlation between yield and its components and the relative importance of each component involved in contributing to seed yield.Twenty one rapeseed genotypes were evaluated based on randomized complete block design with three replications. Significant genotypes effects were exhibited for phenological traits, plant height, yield components except pod length and seed yield, indicating significant genetic differences among the genotypes. High broad sense heritability were determined for phenological traits, plant height and seed yield demonstrating selection gain for improving these traits will be high. Pods on main axis and pods per plant had high value of genetic coefficient of variation and also were significant correlated with seed yield. The results of factor analysis exhibited three factors including first yield components (plant height, pods on main axis and seed yield), second yield components (pods per plant, seeds per pod and 1000-seed weight) and fixed capital factor (phenological traits). On the basis of cluster analysis, the genotypes were classified in three groups and the group with high seed yield had high mean values of plant height, days to maturity and pods per plant.

The experiment was conducted in Federal College of Forestry demonstration farm Jos, Plateau State to determine the growth and yield components groundnut as affected by phosphorous fertilizer application on the Jos plateau. The experimental design used was a randomized complete block design (RCBD) comprising of four treatments (0, 20, 40 and 60 kg P ha-1) that were replicated four times on groundnut (SAMNUT 25). Data was collected on germination percentage, plant height, leaf count, number of branches, days to 50% flowering, number of pods/plant, 100 seeds weight, total yield and biomass weight which were analysed using analysis of variance (ANOVA) at 5% level of probability with Minitab 23. Where significance was declared, Fisher LSD method was used to separate the means. The result reveals that no significant effect was recorded for germination percentage. Highly significant effect of phosphorous was observed on the growth and yield components of groundnut. The highest (34.63 cm) plant height, leaf (100.78) count, number (27.13) of branches, days (27.75 days) to 50% flowering, number (34.50) of pods/plant, 100 seeds (52.08 g) weight, total (2.26tha-1) yield and biomass (5.42 tha-1) weight at the application of 60 kg P ha-1. Thus, groundnut farmers are encouraged to engage in the application of 60kg P ha-1 for optimum growth and yield. Further research on other varieties should be conducted to ascertain the best variety and phosphorous rate for optimum groundnut production in the study area.
