Abstract The importance of red cabbage for expanding the range of vegetable crops in Uzbekistan is highlighted in this paper. The results of three-year (2018-2020) studies on the comparative assessment of the effectiveness of three spring planting dates (March 5-9, 13-16 and 25-27) at three seedling ages (70, 60 and 50 days) at each planting date were presented. It was revealed that the later the seeds are sown to obtain seedlings for spring culture, the faster the seedlings appear and the more the seedlings form leaves. With the postponement of the timing of planting seedlings, the survival rate of seedlings increases. It has been established that the later the seedlings are planted, the higher the temperatures are the growth of plants and the formation of heads. The most unfavorable temperature conditions are formed when the seedlings are planted on March 25-27, which causes a delay at the beginning of the formation of heads of cabbage, an increase in the number of leaves of a root rosette, a decrease in the setting and average weight of heads of cabbage and their marketability. The best indicators of head set-up, their average weight and marketability, yield per unit area are provided when planting on March 14-16, 70 and 60-day old seedlings. Planting seedlings on March 25-27, seedlings of any age, due to the formation of heads of cabbage at excessively high temperatures, delays the flow of products, reduces the setting, average weight and marketability of heads of cabbage and significantly reduces the yield per unit area. It is recommended for a spring culture to plant on March 14-16 with 70 and 60-day old seedlings and not allow planting at the end of March.

In northern Indiana, jack-o-lantern pumpkins (Cucurbita pepo) can be planted from late May through June to produce mature fruit for sales associated with Halloween. Field trials were conducted to evaluate the influence of planting date on pumpkin yield and yield components. `Gold Medal' and `Magic Lantern' pumpkins were each seeded on three planting dates (PD) in 2002 (31 May, 10 and 20 June 10) and 2003 (5, 16, and 25 June). Each planting date was harvested between 100 and 110 days after planting. The weight per plant of pumpkins that were completely mature (orange) was greatest for the June 10 planting in 2002 (14.9 kg vs. 12.5 kg for 1st and 12.2 kg for 3rd PD), but did not differ among dates in 2003 (PD1: 10.9 kg, PD2: 10.4 kg, PD3: 9.0 kg). The number of orange pumpkins per plant was lowest for the 20 June 2002 planting (1.63 vs. 1.88 for 1st and 1.91 for 2nd PD) but did not differ among dates in 2003 (PD1: 1.08, PD2: 1.20, PD3: 1.19). The average weight of an orange pumpkin was lowest for the 31 May 200 planting date (7.17 kg vs. 8.35 kg for 2nd and 7.89 kg for 3rd PD) and highest for the 5 June 2003 planting date (10.6 kg vs. 9.07 kg for 2nd and 8.16 kg for 3rd PD). In both years the last planting date produced the least weight per plant, and in 2002 the fewest number, of pumpkins that had begun to turn orange plus fully orange pumpkins. The two cultivars produced similar weight per plant and responded similarly to planting date, but `Gold Medal' produced fewer and larger fruit. No planting date consistently produced the greatest yield or largest fruit.

An experiment was conducted at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh, during the period from October 2014 to March 2015 to study the effects of planting date and growth hormone on the growth and yield of cauliflower. The experiment consisted of two factors; Factor A: Three planting dates, such as P1: Planting on 1 November; P2: Planting on 15 November and P3: Planting on 1 December; Factor B: Four levels of Growth hormone, such as H0: No Hormone (control); H1: 10 ppm IAA (Indole-3 Acetic Acid); H2: 70 ppm GA3 (Gibberellic Acid) and H3: 10 ppm IAA + 70 ppm GA3. The experiment was laid out following Randomized Complete Block Design (RCBD) with three replications. In case of planting date, the highest plant height (63.26 cm), number of leaves per plant (24.13), leaf length (59.26 cm), leaf breadth (19.31 cm) at harvest, curd diameter (22.25 cm), marketable yield per hectare (28.11 t ha-1) were recorded from P2 and the lowest of those parameters were recorded from P3. In case of growth hormone the highest plant height (63.10 cm), number of leaves per plant (23.66), leaf length (59.05 cm), leaf breadth (18.98 cm) at harvest, curd diameter (22.39 cm), marketable yield per hectare (29.88 t ha-1) were recorded from H3 and the lowest of those perameters were recorded from H0. Combination of planting date and growth hormone the highest plant height (65.96 cm), number of leaves per plant (26.42), leaf length (63.64 cm), leaf breadth (20.92 cm) at harvest, curd diameter (25.75 cm), marketable yield per hectare (31.03 t ha-1) were recorded from planting on 15 November and 10 ppm IAA with 70 ppm GA3 (P2H3) and the lowest parameters (21.75 t ha-1) were recorded from planting on 1 December and no hormone (P3H0). It is apparent from the above results that the combination of planting on 15 November and 10 ppm IAA with 70 ppm GA3 (P2H3) was more productive from the other combinations.J. Environ.

Experiment was conducted to study the effect of seven different planting dates from the month of August to November using four different varieties of Gladiolus viz., Chandni, Big Time Supreme, White Prosperity and Snow Princess, for vegetative and floral parameters. In the vegetative parameters studied variety White Prosperity recorded the highest plant height (128.84 cm), highest number of leaves (9.03) and number of tillers (1.47) during September planting date. Whereas lowest plant height (87.64 cm) was recorded in the variety Chandni during September planting only. The vegetative parameters studied were also dependent on genotype and also interaction between variety and environment. November planting time showed good number of florets (16.06) and also floret diameter (9.42 cm) which was followed by September and October planting dates. Variety White Prosperity produced more number of florets per spike (22.72) in November and floret diameter (11.85 cm) in October planting. For floret parameters there was no significant difference on effect of date of planting and this was mainly due to genotypic characteristic of individual varieties studied. Better spike parameter attributed to the prevalence of favorable environment conditions during October planting time. Among the varieties studied White Prosperity showed highest spike length (105.62 cm) at first floret opening and 107.39 cm during last floret opening. The highest rachis length was also recorded by variety White Prosperity (54.00 cm) at first floret opening and 57.41 cm at last floret opening. October planting was found superior for Spike and rachis length in four different varieties studied.

To determine the influence of sorghum variety, planting dates and ages of harvest on growth parameters and forage yield of grain sorghum (Sorghum bicolor L. Moench) in Shika, Nigeria, an experiment was conducted in split plots in the National Animal Production Research Institute, Shika, Nigeria. The experimental treatments comprised of two sorghum varieties (SAMSORG-16 as V1 and SAMSORG-17 as V2), three planting dates (15th June, 30th June and 14th July as P1, P2 and P3) and three ages of harvest (6, 10 and 14 weeks after sowing as C1, C2 and C3), respectively. Results showed that plant height of sorghum bicolor significantly (P<0.05) differed between variety with higher values in Samsorg-16. Plant height, number of leaves and leaf area index (LAI) decreased (P<0.05) from 15th June to 14th July planting date. However, there was a significant increasing trend (P<0.05) in these parameters as ages of harvest advanced from 6 to 14 week after sowing (WAS). Significant (P<0.05) interaction effect between variety and planting date was observed for plant height.  Similarly, significant (P<0.05) interaction effect was observed in the number of leaves and LAI. There was non-significant (P>0.05) effect of variety on fresh and dry forage yields. Fresh and dry forage yields declined from 54.73 and 10.49 t/ha to 30.72 and 6.11 t/ha from 15th June to 14th July planting dates, respectively. Whereas fresh and dry forage yields increased from 12.22 and 1.37 t/ha to 58.94 and 14.47 t/ha as ages of harvest increased from 6 to 14 WAS,

A factorial experiment was conducted with a completely randomized design to evaluate the effects of planting date and density on calendula herbs and peppermint. It had 3 replicates and was done in Khosroshahr research farm, Tabriz in 2006. Under studied factors were: 3 planting dates (10 May, 25 May and 10 June) in 4 densities (25, 35, 45, 55) of the plant in square meters. The results of variance a nalysis showed that there was 1% probability significant difference between the effects of planting date and bush density on the leave number, bush height and the bush dry weight. But the mutual effect of the plant date in mentioned traits density was insignificant. Regarding the traits mean comparison, the total maximum dry weight was about the 55 bush density in mm. Also, the bush high density in mm causes the bush growth and its mass reduction. When there is the density grain, the flower number will increase due to bush grain in surface unit. Overall, we can conclude that 10 June planting and 45 bush density in mm is the most suitable items and results in favored production with high essence for these crops.

Indian mustard plants are the main vegetable crops consumed by urban communities. The need for this vegetable increases along with the increase in culinary tourism in each region and the government's appeal on sustainable food home. One effort made to meet the needs of vegetable mustard in urban areas can be cultivated using polybags. The main problem of vegetable cultivation on polybags is the availability of soil media. To overcome the limitations of soil media it is attempted to substitute it with organic litter enriched with MOL (local microorganisms). The purpose of research is to find the right combination of planting media for mustard plants. The results showed that the composition of K7 = soil: compost: litter of hay: litter of maize (2: 1: 1: 1) best on plant length, number of leaves, length of root leaves and number of roots while the wet weight of mustard plant (g) K7 = soil: compost: litter of maize: litter of corn (2: 1: 1: 1) and K8 = soil: compost: litter of maize: litter of maize: cocopeat (2: 1: 1: 1: 1) or soil: compost + urea. Increased weights of wet mustard by 63% compared to soil media and 20% compared to soil composition: compost + urea. Organic straw in the form of straw: litter of corn stalk: cocopeat enriched with MOL are able to become ready-made planting media on the cultivation of indian mustard plants in polybags.

Refined nutrient delivery systems are important for environmentally friendly production of cut flowers in both soil and hydroponic culture. They have to be closely orientated at the actual nutrient demand. To solve current problems, express analysis and nutrient uptake models have been developed in horticulture. However, the necessity of relatively laborious analysis or estimation of model input parameters have prevented their commercial use up to now. For this reason, we studied relationships between easily determinable parameters of plant biomass structure as shoot height, plant density and dry matter production as well as amount of nitrogen removal of hydroponically grown year-round cut chrysanthemums. In four experiments (planting dates 5.11.91; 25.3.92; 4.1.93; 1.7.93) with cultivar `Puma white' and a fixed plant density of 64 m2, shoots were harvested every 14 days from planting until flowering, with dry matter, internal N concentration and shoot height being measured. For each planting date, N uptake (y) was closely (r2 = 0.94; 0.93; 0.84; 0.93, respectively) related to shoot height (x) at the time of cutting and could be characterized by the equation y = a * × b. In the soilless cultivation system, dry matter concentrations of N remained constant over the whole growing period, indicating non-limiting nitrogen supply. In agreement with constant internal N concentrations, N uptake was linearly related (r2 = 0.94 to 0.99) to dry matter accumulation. It is concluded that shoot height is a useful parameter to include in a simple model of N uptake. However, in consideration of fluctuating greenhouse climate conditions needs more sophisticated approaches including processes such as water uptake and photosynthetically active radiation.
