Two processes must take place in order that Prosopis seed can germinate: water imbibition and gaseous exchange. However, various types of inhibition caused by seed envelopes, i.e., impermeability to water, impermeability to oxygen, mechanical barrier to radicle protusion, etc., can result in dormancy of the seeds. Repeated attempts to germinate Prosopis seed with intact endocarps has yielded, acco

A seedling is young plant saprophytes developing out of plant embryo from a seed up to one metre of height and the term seedling production is the production of seedlings for a certain purpose, especially plantation. The scope of seedling production has been brought by various issues on environmental protection, forest production, tree improvement, ecosystem balance, forest regeneration and many

Seeds are to be tested before use or sowing in the beds or fields as the success or failure of artificial regeneration work depends on the quality of seeds. When the treatment is given before sowing in the field, it is called pre-sowing treatment. If some species of seeds are not treated, germination may be delayed or germinate irregularly. And in order to hasten germination of such seeds, they h

The timing of Prosopis seed collection and subsequent planting programs can make it advantageous to have some means of storing viable, high quality seed. Before storing, of course, the seed must be properly dried. In storing, the respiration of seed must be reduced to the lowest possible level by lowering storage temperature. The duration of storage may be short-term, i.e., up to one year,

It is important to package seed in dry containers for proper storage. For small quantities of seed, these containers may be tin cans, jars, or pots that are glazed on the inside; even reinforced boxes or bags can be suitable. Metal or plastic jerricans, or drums are often used to package large quantities of seed. Regardless of the type of container employed, it should be of standard size a

Prior to storage or sowing, the physiological quality of the seed should be assessed; this is especially important if seed is to be stored for a long period of time before sowing. The following quality tests should be carried out by trained personnel: Sampling

Seed must be dried before it is stored or sown; if not, the seed can spoil and rot. In general, Prosopis seed should be dried to a moisture content of 10 to 12 percent, or even less, prior to storage. Under these conditions, respiration continues at the low level required to keep the embryos alive, and only relatively small amounts of the stored carbohydrates are converted into carbon diox

Local Varieties Local varieties are nothing but traditional varieties but which are susceptible to diseases and pests and are having long duration for maturity. In case of rice - Krishnakatukalu, Basangulu. High Yielding Varieties High yielding varieties are dwarf varieties and having short duration with resistant to pests and diseases with maximum yield potential. Eg: I.R -64, I.R - 36, I.R - 50.

Although, Pakistan 80 per cent cultivatable area is irrigated but the edible oil needs are met through imports. The import bill rising from Rs77 million in 1969-70 to Rs39 billion in 2002-03 has overburdened the exchequer. In 1970-71, oilseeds occupied nearly 3 per cent of the total cultivated area which went down to 2.5 per cent by 2002-03. Nearly 30 per cent of the total need is met through loc
