The correlation between plant density and yield average shows that the volume of yield increases in varieties of large and medium-size seeds up to a plant density of 285-400 thousand/ha, after which it declines. On the basis of the results, yield averages at plant densities of 285-334 thousand plant/ha are 0.17 t/ha higher than those achieved at low density (200 thousand plant/ha). High levels of potassium fertilizer did not enhance the yield of dry beans. With adequate-water supply the high level of potassium decreased the number of pods and seeds per plant compared with a basic level of fertilizer, which could ensure 2.5 t/ha yield.

investigations were made on the relationship between plant density and plant height, and on the yield, thousand seed mass, and ratio of diseased and broken seeds of varieties with different seed sizes. Experiments were carried out to analyse the effects of potassium on the yield, bacterial diseases and nutritive quality of the seed of bean varieties. Three dry bean cultivars representing the small, medium and large seed size groups were investigated. Six plant density treatments were chosen based on theoretical seed norms, taking the germinative value of the seeds into consideration. The correlation between plant density and yield average showed that the volume of yield increased for varieties with large and medium-sized seeds up to a plant density of 285-400 thousand/ha, after which it declined. On the basis of the results, yield averages at plant densities of 285-334 thousand plants/ha were 0.17 t/ha higher than those achieved at low density (200 thousand plants/ha). At greater plant density the plant height increased in the case of large-seeded varieties and there was a considerable decrease in the thousand seed mass. With an adequate water supply a high level of potassium decreased the number of pods and seeds per plant compared with the basic level, which gave a yield of 2.5 t/ha. The use of high rates of potassium fertilizer decreased the number of infected seeds, but the differences were only significant for the small-seeded variety. A moderately high potassium level was advantageous for food quality, particularly during drought.

Growth Development

Summary. The effect of plant density on growth, development, yield and quality of kabocha (buttercup squash) (Cucurbita maxima) was examined during 1992–93, at a field site in Cambridge, Tasmania. Plant densities ranged between 0.5 and 4.7 plants/m2. Marketable and total yields were fitted to a yield–density model. Total yield followed an asymptotic trend, approaching 33 t/ha at 4.7 plants/m2, while marketable yield had a parabolic relationship with density. Marketable yield increased to a maximum of 18 t/ha at 1.1 plants/m2, while declining at higher densities because of increased numbers of undersized fruit. Yield of vine marked and callused fruit did not vary with density, but represented a significant proportion of the total yield at all densities. High plant density reduced vegetative growth per plant due to competition for limited resources; as shown by decreased leaf area, number and length of vines, and plant dry weight. Yield tended to decline at high densities because of fewer female flowers and increased fruit abortion per plant. Plants at low densities had more vegetative growth but decreased yields, as increased abortion of fruit relative to the higher plant densities left only 1–2 large fruit per plant. Economic returns varied with plant density. At high densities, variable costs increased (particularly due to high seed cost) while gross income declined reflecting the relationship between marketable yield and plant density. The gross margin therefore declined at high densities.

Maximizing yield and quality of processing broccoli (Brassica oleracea L. var. italica) is critical to successful production in Atlantic Canada. Field studies were conducted from 2004 to 2006 to evaluate the effect of plant density and trickle irrigation on the yields and incidence of hollow stem for early and late transplanting of broccoli. Treatments consisted of five plant densities ranging from 3.17 to 6.35 plants m–2. Each plant density was either not irrigated or trickle irrigated to maintain at least 25 mm total precipitation per week. The highest marketable yield was achieved at 5.56 plants m–2 when grown in an early transplanting with trickle irrigation in a single row with 90 cm between the row and 20 cm within the row. Overall, earlier transplanting dates were more productive. Trickle irrigation increased marketable yield by an average of 12% over the 3 yr of tests. Average head weight, head diameter, and the incidence of hollow stem decreased as plant density increased. Leaf tissue N was not affected by plant density, trickle irrigation or transplanting date.Key words: Brassica oleracea L. italica, plant density, yield, growth

The hypothesis that by increasing carrot (Daucus carota) plant density the contribution to seed yield by the primary umbels would increase, and that therefore both seed yield and seed quality would increase, was examined in two experiments in different years in Canterbury. A radial trial design provided plant densities from 2 to 84 plants/m2 and from 4 to 100 plants/m2 in experiments one and two respectively. Seed yield increased with increasing plant density in both experiments, and at the highest density the primary umbels contributed 90% (experiment one) and 60% (experiment two) of the seed yield. In both experiments seeds from the primary umbels had a greater thousand seed weight and higher germination than those from the other order umbels, and for the second experiment they also had higher seed vigour. The quality of seeds from the primary umbels was consistently higher than that of seeds from the secondary umbels across all plant densities, and for the latter, both germination and seed vigour declined as plant density increased. These results therefore support the hypothesis, and densities higher than the 20 plants/m2 currently used commercially have the potential to increase both seed yield and quality.

ABSTRACT In South Africa there are no established spacing recommendations for determinate tomato cultivar production under closed hydroponic systems. This study was conducted to determine yield and quality of hydroponically grown determinate tomato cultivars at different plant densities. Four determinate tomato cultivars (Dynimo, Mariana, Mion and Sama) were subjected to four plant densities (10, 16, 20 and 25 plants/m2) during the spring/summer and summer/fall seasons. Experimental layout was a randomized complete block design in a factorial scheme of four plant spacing x four cultivars with three replicates. There were no significant differences in marketable yield between the cultivars tested during the spring/summer and summer/fall seasons. Cultivar Mion showed higher incidence of blossom end rot, while Mariana showed the highest fruit rot during the spring/summer season as compared to the other cultivars. During the spring/summer season, marketable yield increased with increased plant density with the highest yield obtained at 25 plants/m2 followed by 20 plants/m2. During the summer/fall season, plant density did not show a significant effect on total and marketable yield although a tendency for declined yield with increased density was observed. Number of fruit per plant as well as fruit size decreased with increased plant density during both seasons which did not have an effect on overall yield per plot area. Increasing the plant density to 25 plants/m2 can improve marketable yield of determinate tomato cultivars during spring/summer season while using a plant density of 10 plants/m2 will be more cost effective during the summer/fall season. This information will enable farmers to optimise yield and quality of determinate tomato cultivars under closed hydroponic systems.

Garlic is primarily grown for its cloves used mostly as a food flavoring condiment. Previous studies carried out on plant density indicate its direct influence on yield. Plant density depends on the genotype, environmental factors, cultural practices, etc. This study was established to determine the effects of different between-row spacing on growth, yield, and quality of four local accession of garlic. It was laid out on two-factorial Randomized Complete Block Design with three replications during two years. Four local accession of garlic (Langroud, Tarom, Tabriz and Hamedan) were culture in three between-rows spacing (15, 25 and 35 cm) during two years. The results of two cultivated years were different. Plant density changed when garlic cultured with different between row spacing. In present research plant yield increased when the lower between row spacing and high plant density were used but the yield improvement occurring at increased plant stand is offset by the reduction in bulb size and some quality indices such as total phenol and antioxidant which severely affects quality and market value, when garlic is produced for fresh market.

In order to understand the effect of organic fertilizer on yield of anise, an experiment was conducted in the form of split-plot in randomized complete block design with three replications in Mashhad, Khorasan Agriculture and Natural Resource Research Center. Four treatments of fertilization: the control, vermicompost - 5 t/ha, cow manure - 25 t/ha, and mineral fertilizer (NPK) - 60 kg/ha (the same rate of each nutrient) were applied as the main factor. The second factor was plant density, applied at three levels: 17, 25, and 50 plants/m2. The results showed a significant effect of fertilizer on the number of umbels per plant, number of umbellets per umbel and canopy cover. Plant density had a significant effect on grain yield, biological yield, the number of lateral branches, essential oil percentage and yield of essential oil. Seed and essential oil yield were the highest in the case of the application of vermicompost and plant densities of 50 and 25 plants/m2 respectively.

The performance of plantain fruit yield and quality under different planting densities under an influence of irrigation system was investigated at International Institute of Tropical Agriculture, Ibadan, Oyo State, Nigeria. Experiments were set up as a split plot fitted into randomized complete block design (RCBD) with three replications. Main plots are irrigation system while sub-plots are plant densities. Treatments included four plant densities (1 x 2, 2 x 2, 2 x 3, and 3 x 3 m), two irrigation systems and their combination where irrigation system was the main plot and plant density the sub-plot. Over 2,000 agbagba suckers were pared and hot–water treated, and planted during the first week of the experiment. Manure was applied at the rate of three spades full per plant for nutrient supplement; and mulching was done. Weeds were manually controlled as at when due. Plantain diseases like yellow sigatoka and black sigatoka were also controlled manually by de-leafing infected leaves to prevent disease spread. Data were collected and analyzed using ANOVA. Duncan multiple range test (DMRT) was used for mean separation at 5% level of significance. The results of ANOVA showed that there were significant effects (P < 0.05) due to irrigation application for all measured parameters whereas effects due to plant densities were significant for only these parameters; number of suckers (NOS), sucker height (SUHT), number of leaves on sucker (NLSC), bunch weight (BWT), number of hand (NHND), total number of finger (TFNG) and number of sucker at flowering (NSCK). Therefore, it can be concluded that plant spacing, and regular water supply plays a significant role in obtaining good yield in plantain production

Relevance. The most popular cucumber in Russia is pickling type (lenght 10-12 cm). There are not a lot of varieties this type cucumber for high wire and LIT crop in Russian seeds market.Methods. Were tested russian varieties F1 Ciborg, F1 Bavarets (Gavrish company) in compare F1 Bjorn (Enza Zaden, Netherlands) – the most popular in Russia now. Russian customer prefer pickling type because of traditional Russian cuisine. Prices of pickling type cucumber at autumn-winter time in 1-1.5 times more than middle size type cucumber. We had artificial light 240 Wt/sq.m, sodium lamps, our substrate was rockwool – Belagro (company from Belarusian republic). This rockwool have normal quality for short crop (3-4 month for growing cucumber), our plant density 2.76 plant/sq.m it was optimal for our light conditions (natural light in our region and artificial light).Results. Fourteen days after we put plants on slabs we had problems with plants of both russian varieties (F1 Ciborg and F1 Bavarets). We saw yellow parts in leaves, decrease length of stems, lost flowers. We made a decision about too high level of artificial light. We had only one opportunity for decrease it switch off 50% of lamps. We made it and we had 120 Wt/sq.m that. Therefore, we spent 50% less electricity for russian varieties. We think varieties F1 Ciborg and F1 Bavarets not very good for winter crop and we had good results because in our situation we have winter-spring crop, and every day the part of artificial light decrease and the part of natural light increase. F1 Ciborg had a problem with CGMMV and was deleted in 24th week of 2020. But we suppose it depend from a lot of conditions: quality of labor, protection plants. We think it is necessary more additional research. Total yield (for ten weeks of harvesting in winter-spring crop) F1 Bavarets – 32.4 kg/sq.m., F1 Ciborg – 31.9 kg/sq.m more then had F1 Bjorn – 28.9 kg/sq.m. The best marketable condition was F1 Ciborg, the second F1 Bjorn.
