This study was conducted with an area of 540 square meters excluding canals and was divided into twenty plots. Each plot was measured 3m x 9m. The experimental area was laid out following Randomized Complete Block Design (RCBD). The study aimed to determine the effect of different row spacings and schedule of urea application in medium level on the yield of sweet corn. Results of the analysis showed that the average length and average circumference of corn ears in centimeter per plot per treatment both showed no significant difference as affected by different row spacings and schedule of application of urea. Results of the Analysis of Variance (ANOVA) on the average weight and total weight of corn ears in kg per plot per treatment showed that there was significant difference on the yield of sweet corn using row spacings. However, no significant difference on the schedule of application of urea. Thus, R2 is recommended in terms of longest husk, biggest circumference of husk, and heavier husk of corn ears. On the other hand, R1 is recommended to obtain more husk of corn ears and R5 is recommended to obtain heavier husk of corn ears.

Tolerance of eight processing sweet corn hybrids to nicosulfuron was evaluated in field studies conducted at Arlington, Wis. in 1988 and 1989. Magnitude of sweet corn vigor reduction varied between years. Greater vigor reduction occurred to ‘Jubilee’ sweet corn than to the other seven hybrids. Injury to the hybrids increased as nicosulfuron rate increased. In 1988, some of the hybrids were stunted slightly by all of the herbicide rates, but within a hybrid there was no significant difference among herbicide rates. In 1989 none of the hybrids, including Jubilee, was stunted by even 140 g ai ha–1nicosulfuron compared with the corresponding check. Effects of nicosulfuron on yields of the eight hybrids in 1988 and in 1989 are best described by a quadratic regression equation.

Abstract This research was aimed to get the role of nitrogen and the role of substitution synthetic nitrogen with organic nitrogen on red ginger cultivation. The research was conducted from March to September 2020 at Wonorejo, Jatiyoso, Karanganyar. The research was carried out using randomized complete block design (RCBD) with 1 factor, 4 treatments, and 6 repetitions namely P0 (Control), P1 (0.3 ton ha-1 ZA), P2 (0.15 ton ha-1 ZA + 1.99 ton ha-1 organic fertilizer), and P3 (3.98 ton ha-1 organic fertilizer). The data will be analyzed using analysis of variance and continued with a DMRT level of 5% if there is a significant difference. The result showed that the substitution of ZA (Zwavelzure Ammonium) fertilizer with organic fertilizer increased the yield of red ginger cultivation. The use of organic fertilizer with 3.98 ton ha-1 increased the number of leaves, the number of saplings, fresh and dry strawweight, fresh and stored rhizomes weight, and the length of rhizomes..

The study was conducted to determine the yield of peanut as affected by different row and hill spacings. The experiment was done under the soil and climatic requirements of Zamboanga Sibugay, Philippines with an average temperature of 27.3 0C. The experiment was laid using Randomized Complete Block Design (RCBD) with sixteen combined treatments. An area of 80 square meters was divided into 16 plots, each plots measured 1m by 5m excluding canals. There were two factors used in the study, the different rows and hill spacings. The row spacing used were R1 (12 inches), R2 (16 inches), R3 (20 inches), R4 (24 inches) and the hill spacing used were H1 (6 inches), H2 (7 inches), H3 (8 inches), H4 (9 inches). Complete fertilizer was drilled at the base of the plant 30 days after planting at the rate of 1.83 grams per hill. Tobacco spray was applied twice, first at 15 DAP and second at 50 DAP and kakawate spray was applied 43 days from planting to prevent and repel insect pest. Result revealed that the average number of pods per plant per plot, average weight of pods in gram per plant per plot, total number of pods per plot, and total weight of pods in kilogram per plot had no significant difference as affected by different row and hill spacings. However, the result on the average number of seeds per plant per plot showed that there is a significant difference among treatments. Statistical analysis revealed that the computed “f1” is greater than the tabulated “f1” at 5% level of significance.

Abstract: The objective of this work was to evaluate the influence of the number of replicates on experimental precision in corn (Zea mays). Data on the grain yield of 15 corn cultivars, evaluated in a randomized complete block design, with nine replicates (r = 9), were used. From the experiment with nine replicates, further experiments were conducted with combinations of 2, 3, ..., r-1 replicates. The analysis of variance was carried out for each experiment. Experimental precision statistics and central tendency and variability measures were calculated, dispersion diagrams were prepared, and models of these statistics were adjusted as a function of the number of replicates. The number of replicates was determined by the visual analysis of the graphs with the experimental precision statistics. Increasing the number of replicates improves the estimates of experimental precision but decreases gains. Therefore, the increase in the number of replicates is important to improve corn cultivar discrimination. Six replicates are recommended as the benchmark for experiments with corn cultivars. Fasoulas’ differentiation index, based on the percentage of significant contrasts, is an appropriate statistic for evaluating experimental precision.

Shallot is an important spice and seasoning in Indonesia. It is consumed almost daily in many dishes. The objective of this experiment was to study the effect of the medium and the variety on the yield of shallots grown in a polybag. The experiments were arranged in a two-factorial randomized complete block design with three replications. The factors were medium (1 soil: 1 paddy husk ash and 1 soil: 1 compost) and variety (Agrihorti 1 and Mentes). Data were statistically analyzed by Analysis of Variance (ANOVA), and the means were compared using Honestly Significant Difference (HSD) at P < 0.05. There was no interaction between medium and variety. Overall, all treatments did not significantly affect yield. Varieties were significant differences on bulb diameter; however, they were not significant differences on bulb height, fresh bulb weight per polybag, and bulb number per polybag. Those media are considered as precise media due to they contain organic materials.
