Mineral nutrients are essential to plant growth and development. The present study aimed to evaluate the effects of mineral fertilizer doses and N:P:K ratio on growth, yield, and raw material quality of the tea variety PH10 to improve the production of high-quality tea products. The field experiment was conducted from 2015 to 2017. A two-factor experiment was designed by split-plot design with three replications. The mainplot treatments were three fertilizer doses of N  for one metric ton of fresh shoot products (30, 40, and 50 kg N ha-1). The subplot treatments were two NPK ratios (3:1:1 and 3:1:2). Plant height, leaf canopy, plant diameter, shoot yield parameters, shoot components, biochemical compounds, and sensory quality for Oolong and Sencha tea products were evaluated. The results showed that increasing fertilizer doses from 30 up to 40 kg N per ton of fresh product improved remarkably growth, yield, and tea quality of PH10 variety. Different fertilizer ratios resulted in variations in plant growth, the content of carbohydrate, sensory quality for taste and flavor as well as total sensory quality with higher values at NPK ratio of 3:1:2. Applying mineral fertilizer with an NPK ratio of 3:1:2 and 40kg N per ton of fresh shoot products was recommended to bring about the most benefits of tea yield and quality as well as economic profit.

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.
