Meterology is the word derived from � meteoro � which means �above the surface of earth� and �logos� means �scientific study�. It is actually a branch of Physics and deals with the study of lower atmosphere. In short, it is the study of characteristics and behavior of atmosphere. It explains and analyses the changes of individual weather elements such as air pressure, temperature and humidity that are brought about due to the effect of insolation (radiation from the sun received by earth�s surface). Weather monitoring device installed near an agricultural field The application of meteorology in agriculture is called Agriculture meteorology or Agrometeorology . In plain words, agrometeorology is the application of study of the effects caused by the changes and behavior of the climate on agriculture. The measurements and analysis done for longer durations enables the agriculture world about the coming climatic changes in advance. There are numerous possibilities of the applications of ...

Sowing  (or seed sowing) is defined as the process of placing the seed in soil to germinate and grow into plant.  In comparison, planting is the putting the plant propagules in soil for growing plants. Propagules can be seedlings, roots, tubers, leaves, or cuttings.  And transplanting is term used for the planting the seedling grown into nursery to different field, pot or plot for different purposes. Seed Broadcasting by Farmer Methods of Sowing Seeds may be sown directly or transplanted. For transplanting, the seeds are sown in nursery and the nursery is later transplanted to field. The methods of sowing are enlisted and detailed as under; a) Broadcasting b) Dibbling c) Drilling d) Sowing behind the country plough e) Planting f) Transplanting 1. BROADCASTING Broadcasting is one of the oldest and most common methods of seed sowing, where the seeds are just spread on the soil; the seeds may or may not be covered with soil. Broadcasting may be done manually, or through mech...

Wheat is the most important cereal crop in Pakistan and staple food. Wheat has a large share of cultivated land in rabi season and hence large production is expected. The seed selected should be pure, healthy and free of disease. The seed should be bought from trusted sources, or the varieties approved by the local agriculture department should be used for sowing. The germination rate of seed should not be less than 85% or the seed rate should be increased accordingly. Wheat field For late sowing ( pachaiti kasht ), the seed should be increased to some extent because the germination rate is less in low temperature and less number of tiller form. The production of wheat is mainly from primary tiller, so in order to get sufficient produce in late sown crops, seed rate is increased to increase the number of primary tillers. In addition to this, increase in seed rate is also beneficial for the weed control, because in the presence of more wheat seedlings lesser number of weeds will be able...

Good quality seeds are those which are of same variety and contain little to no impurities and shows a good performance in the field.  Following criteria can be used to describe the quality of good seed; 1. Varietal characteristics 2. Seed lot characteristics 3. Seed viability Seeds of pulses 1. VARIETAL PURITY CHARACTERISTICS Varietal purity is mainly defined as the genetic or cultivar purity and can be described by its physical & chemical traits and crop attributes. a) Seed factors True varietal seeds can be characterized by its specific traits such as the length, width, shape, size, color and aroma. b) Chemical analysis A range of chemical tests can also be used to differentiate between varieties.  Factors such as alkali digestion, color, amylase content, gel consistency and protein helps to discriminate between varieties. c) Crop factors Physical characteristics of crops are normally constant that includes plant height, time to reach maturity, plant color and plant gro...
