Barley is one of the popular crops cultivated since ancient time in the world. Barley is one of the main cereal crops produced in the World and it is one of the most ancient crops among cereals and has played a significant role in the development of agriculture in the world. It is commonly used for food, animal feed and beverage value. The most important factors that reduce yield of barley is poor soil fertility, blanket recommendation of fertilizers, soil acidity (low soil pH), diseases and insects, poor crop management practices. The main objective of this paper is to review the effect of NPS fertilizer rates on food barley yield and yield components. Balanced fertilization is the key to sustainable crop production and maintenance of soil health. The yield of crop is depending upon the combined effect of many factors. Among these factors, the production and productivity is declining from time to time because of lack of combined application of input like recommended amount of fertilizers and management practices. Based on the review on the effect NPS fertilizer rate on phenology, growth and yield parameters of food barley. It has both economic and environmental consideration. The application of NPS fertilizer rates shows significant effect on growth, yield and yield components of food barley. It influence on the phonological, vegetative growth, yield and yield related parameters. Days to 50%heading, days to 90% maturity, spike length and number of tiller per plant were significantly affected by the NPS fertilizer rate. Then we should or need to focus on micro nutrients that are considered useless by farmers as well as researchers because those micro nutrients deficiency today shows clinical symptoms at human beings especially on children and infant women. Fertilizer suppliers or cooperative unions should pay attention to supply or blended type of the fertilizer instead of supplying single elements, the fact that the government and recognized researchers should give due attention to blended fertilizer to increase production of food Barley.
Seed quality deterioration is inevitable process. Since seed is a vital input in agriculture which determines not just the production but also the productivity, it is crucial to maintain the seed quality as well as seed vigor during the storage. Storage is a basic practice in the control of the physiological quality of the seed and is a method through which the viability of the seeds can be preserved and their vigor kept at a reasonable level during the time between planting and harvesting. Many researches on seed storage period have been investigated that seeds can be stored for short period is found in least deterioration. In contrast changes associated with seed deterioration are depletion in food reserve, increased enzyme activity, increased fat acidity and membrane permeability. As the catabolic changes continue with increasing age, the ability of the seed to germinate is reduced. Gradual decrease in the seed quality parameters were observed, as the storage period increase. It is estimated that good quality seeds of improved varieties alone can contribute about 18 to 20 per cent increase in crop yield keeping all the other inputs constant. Lastly using seeds as planting material which stored with in short period of time and in proper environment is very important.
Onion is an herbaceous biennial monocot cultivated as an annual. The higher seed yield in onion cultivars was due to the higher number of seed stalks per plant and to a wider umbel diameter which were influenced by application of N and P fertilizers. The number of flower opening on each day was influenced by the number of hours of sunshine and concentration of phosphorous and nitrogen. N and P treatments tended to lower bolting percentages. The yield of seed per plant increased as the nitrogen in the nutrient solution increased where seed stalks were produced. The effect of early dressings of N on crops grown under conditions when nights are becoming cooler is shown to allow the plants to reach a 'bolting inducible' stage early in the growing season. There is maximum response of onions to P fertilization in the range 0-52 kg ha-1. Plant roots take up nitrogen from the soil solution principally as nitrates (NO3-) and NH4+ ions. Nitrate is the preferred form of N for uptake by most plants, and it is usually the most abundant form that can be taken up in well-aerated soils. Nitrogen fertilizer application improves phosphorus uptake from the soil. Onion absorb phosphorous in the form of H 2 PO 4 -and H 2 PO 4 -. Too much phosphorus level affects plant growth by suppressing the uptake of iron, potassium and Zink. The availability of inorganic phosphorus is largely determined by soil Ph. Leaching losses of nitrate are growing crop cover to absorb the nitrates as rapidly as they are produced. Soil Ph drastically influences the reaction of phosphorus with the different ions and minerals. To increase the yield of onion seed the application of N and P fertilizer should be determined.
The existing paper is review quite a number lookup findings on weeds and weed control in soybean. Soybean is the most important oil seeds and grain legume crop in the world, in terms of whole manufacturing and international trades. However, losses due to weeds have been one of the fundamental limiting factors in soybean production. So, successful weed manipulate is one of the most essential practices for low-priced soybean production. Weeds that germinated at the identical time as soybeans grow faster and hold a cover above and under the pinnacle of the soybean cover and resulted in decreased quality. The role of weeds as alternate hosts for soybean crop pests and ailment and their interference with cultivation operations ensuing greater costs of production. Weeds additionally have impact on the use of fertilizer due to the fact they compete with the crop for nutrients. Weed control chances consist of preventive, cultural, mechanical, and chemical methods. Continuous cultivation of a single crop or crops having similar administration practices permits certain weed species to come to be dominant in the gadget and, over time, these weed species come to be tough to control. The care taken that weeds do no longer need to go to seed, that harvesting equipment is no longer transporting weed seeds, and that clean seed is used for all crops in the rotation; is an essential part of a weed program. Combining weed control method can help maintain weed injury before financial threshold stages and shall be performed rather than a separate manage method.
