Laxogenoside-C (LG-C) has BRs-likely activity and with higher activity stability. In this study, the LG-C and SsS (the mixture of Laxogenoside-A, -B, and -C; isolated from the Smilax scobinicaulis C.H. Wright) were used to conduct the seeding treatment and greenhouse experiments with different application time and concentrations, to clarify the effect on yield and quality of radish (Raphanus sativus L.) for development of a new plant growth regulator. The results showed that 10 μM LG-C and SsS increased hypocotyls, elongation and cotyledon weight compared with other treatment. The greenhouse experiments indicated that the interaction effect of plant growth regulator types and application time was significant for all parameters except for phosphorus content. An application of LG-C or SsS produced a higher yield than multiple times. Compared with T0 treatment, LG-C and SsS sprayed at root enlargement (T4) increased yield by 25.33% and 24.10%, respectively. T4 treatment of LG-C produced the highest yield and free amino acid and phosphorus, but the other parameters not. T4 treatment of SsS not only had the highest yield and water-soluble carbohydrates and water-soluble protein but also improved the other radish quality. In conclusion, this study indicated that the application of SsS at root enlargement with 10 μM improved radish root tubers yield and quality.

Harvest Delay

The effects ReTain Plant Growth Regulator (830 g in 1000 L water/ha) applied to a commercial block of 'Arctic Snow' nectarines 7 days before the first harvest was assessed in relation to harvest delay, fruit size, fruit quality (flesh firmness and brix), as well as the quality of the fruit following export to Taiwan. The untreated block (0.87 ha) and the ReTain-treated block (1.0 ha) were harvested according to the orchard's standard maturation criteria of background colour, size and percent blush colour. Based on picking schedules, the maturation of the ReTain block was delayed by 2.75 days (P<0.05). The fruit continued to grow during this delay and resulted in a 12.3% increase in yield and an increase of 393 packed cartons/ha. There were more (P<0.001) cartons of ReTain-treated fruit packed in grade sizes 69–78 mm diameter and less of smaller size classes (51–66 mm) compared with untreated fruit. The increase in both the number of cartons of class 1 fruit and fruit size on the ReTain block resulted in a Return on Investment (ROI) of 14.7 : 1 with an additional net return of AU$17 655/ha over the untreated block. There was a correlation between fruit size and flesh firmness with larger fruit being firmer than smaller fruit (P<0.001), however, packed ReTain-treated fruit was 3.2 N firmer on average (P<0.001) than packed untreated fruit for all size grades and from all harvests and packs. Brix levels increased (P<0.001) with fruit size but there was no difference (P = 0.568) between ReTain-treated fruit and untreated fruit. Two containers of fruit (early and late picks) were exported to Taiwan. The containers held a temperature of 0.5–2.0°C for the 14–15 day transit time from Australia to Taiwan. ReTain-treated fruit in both containers was 1.7 N firmer (P = 0.022) than untreated fruit upon arrival in Taiwan. After ambient storage (23°C) of fruit from container 1 for 45 h, fruit firmness declined (P<0.001) from an average of 65.7 to 43.2 N and there was no difference (P = 0.826) between treated or untreated fruit. It is concluded that ReTain application to 'Arctic Snow' nectarines can increase financial returns to growers through increased fruit size and quality benefits as well as maintain a higher flesh firmness following export.

SUMMARYThe effects of planting potato tubers on four different sides of two ridge orientations was investigated. Soil temperature was coolest on the northern side, followed by the western, eastern and southern sides. Fifty percent emergence took place in 24, 42 and 49 days for tubers planted on the northern, western and eastern sides, respectively. Only 22% of tubers planted on the southern side emerged. The best yield and quality was obtained by planting on the northern side, followed successively by the eastern, western and southern sides of the ridge.

Background: Onion (Allium cepa L.) is a major bulbous vegetable as well as condiment of family Alliaceae grown in India, originated in Iran and Pakistan. Seed pelleting is a mechanism of applying various materials to the seed that can enhance the seed quality with respect to physiological, physical and health attributes. Seed pelleting make it easy to handle small and irregular shaped seeds.Methods: The present investigation was conducted in the field of Department of Seed Science and Technology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan during seasons of 2016-17 and 2017-18. Result: This experiment comprised of pelleted seeds with different botanicals carried out to determine the effect of sowing dates and seed pelleting and their interactions on plant growth, yield and quality of bulb crop. All the factors in the experiment as well as their interactions showed significant influence on plant growth, yield and yield contributing characters in onion. The seeds pelleted with Azadirechta indica leaf powder + clay and Melia azedarach leaf powder + clay sown directly showed maximum values w.r.t. emergence (91.50 %), plant height at 60 days after sowing (35.35 cm), average leaf length (38.43cm), number of leaves per plant (8.67), number of days to harvesting (233.49), polar diameter (46.72 mm), equatorial diameter (57.77 mm), bulb size index (2699.74 ), neck thickness (12.12 mm), number of bulb per plot (89.00) average bulb weight (75.24 g), bulb yield (6.67 kg per plot or 400.01 q per ha), plant height before neck fall stage (58.55 cm). From the present studies, it can be concluded that onion seeds pelleted with Azadirechta indica leaf powder + clay and Melia azedarach leaf powder + clay showed significant effects for enhancing bulb quality, growth, quality and yield of bulb crop raised through direct seeding.
