Ornamental cabbage

Ornamental cabbages and kales do not tolerate summer heat, so you need to start plants from seed in mid-summer, or purchase transplants at your local garden center.  Sow seeds about six to 10 weeks before the expected date of the first frost in your area.  Seeds must be sown and young plants kept under cool conditions to thrive.  In most climates, this means plants should be started in a greenhouse where the temperature can be controlled.  Alternatively, you can place pots with seeds in a refrigerator for several days to encourage germination.  In cooler climates, sowing seeds directly in the garden may be possible.  Ornamental cabbage and kale seeds require light for germination, so seeds should not be covered with soil.

When purchasing ornamental cabbage or kale transplants, look for large, compact plants that are nearly or fully colored.  Plants will generally not get much bigger after they are planted in the garden, particularly if the roots are pot bound.  Therefore, be sure to buy appropriate-sized plants for the location where they will be used (even though bigger plants will cost more).  How do I grow ornamental cabbage and kale@f1  Wait until temperatures start cooling down, then plant ornamental cabbage and kale in a sunny location in a moderately moist, rich soil.  Bury stems so that the lowest leaves of the plants are flush with the soil surface.  After planting, keep the plants well watered.  Until cool weather arrives, plants won’t have much color.  White, pink, or red pigments will begin to develop when temperatures dip below 50°F.  Once acclimated in a site, ornamental cabbages and kale can survive temperatures as low as 5°F, so plants may last well into November and December.

INTRODUCTION TO FLOWER STRUCTURE

INFLORESCENCE 1. Racemose : Inflorescence with monopodoal branching i.e., the inflorescence axis continues to grow and gives off lateral and axillary flowers. (i) Raceme: Racemose inflorescence having a common axis and stalked flowers arranged in acropetal succession, e.g., Brassica. (ii) Panicle: Axis of raceme is branched. (iii) Spike: Inflorescence is similar to raceme but the flowers are sessile: e.g., Achyranthes aspera. (iv) Spikelet: Very small spike of a compound spike forming a unit; e.g., grasses. (v) Catkin (or Ament) : A pendulous spike or spike-like inflorescence consisting of small unisexual flowers ; e.g., Morus alba. (vi) Spadix : A spike with thick and fleshy axis covered by a large spathe ; e.g., Maize. (vii) Corymb : It is a modified raceme with relatively a short main axis, in which the lower flowers have much elongated pedicels so that the flowers come to the same level ; e.g., Candytuft. (viii) Umbel : It is a modified raceme, in which the flowers have ...

MATURITY INDICES, HARVESTING AND POST HARVEST HANDLING OF FRUITS AND VEGETABLES

-
I. MATURITY It is the stage of fully development of tissue of fruit and vegetables only after which it will ripen normally. During the process of maturation the fruit receives a regular supply of food material from the plant. When mature, the abscission or corky layer which forms at the stern end stops this inflow. Afterwards, the fruit depend on its own reserves, carbohydrates are dehydrated and sugars accumulate until the sugar acid ratio form. In addition to this, typical flavour and characteristic colour also develop. it has been determined that the stage of maturity at the time of picking influence the storage life and quality of fruit, when picked immature like mango develop white patches or air pockets during ripening and lacking in normal brix acid ratio or sugar acid ratio, taste and flavour on the other hand if the fruits are harvested over mature or full ripe they are easy susceptible to microbial and physiological spoilage and their storage life is considerably reduce.

1. Function   To shell groundnut pods and separate kernels . 2. Specification (i) Overall dimension (L x B x H, mm)   600 x 350 x 700 (ii) Capacity   200 kg/h (ii) Power required     Manual 3. General Information     It consists of an oscillating sector with sieve bottom and a handle. Number of cast iron peg assemblies are fitted in the oscillating sector unit.  The groundnut pods are shelled between the oscillating sector and the fixed perforated concave screen.  The decorticated shells and kernels fall down through the perforated concave sieve.  The kernel and husk are collected at the bottom of the unit and separated amnually ...

Weeds

W eeds are plants that are unwanted in a given situation and may be harmful, dangerous or economically detrimental. Weeds are a serious threat to primary production and biodiversity. They reduce farm and forest productivity, displace native species and contribute significantly to land and water degradation. The costs of weeds to the natural environment are also high, with weed invasion being ranked second only to habitat loss in causing biodiversity decline. Despite considerable government and private sector investment, weed invasion still represents a major threat to both the productive capacity of land and water and the integrity of our natural ecosystems. An efficient weed control program can only be developed after the weed has been properly identified. Weeds can be managed using many different methods. The most effective management of weeds is usually achieved through collaboration and cooperation, in partnerships between the community, land owners, agriculture, industry and the...

Essential Oil Extraction Process

-
·          Rather than being synthetically manufactured in labs, essential oils are extracted from plant materials through removal methods that are suited to the specific plant part containing the oils. ·          Essential oils are the liquids that are isolated from plants when introduced to solvents – they are liquefied versions of the plants! ·          Popular extraction methods include: Steam Distillation, Solvent Extraction, CO2 Extraction, Maceration, Enfleurage, Cold Press Extraction, and Water Distillation.  ·          The method of extraction affects essential oil quality by way of pressure and temperatures applied. ·          Some extraction methods are best suited to particular plant types and parts; for example, Cold Press extraction is better than Enfleurage...
