Find out the Effect of Organic Manure Integrated Nutrient Management on Quality of Cauliflower

There has been substantial increase both in the production and productivity of the vegetables with the adoption of high yielding varieties and improved production technologies. Cauliflower is a heavy feeder of nutrients they’re by the use of chemical fertilizers is increasing day by day and the indiscriminate use of chemical fertilizers has simultaneously resulted in many problems like degradation of soil productivity, environment pollution, depletion of non-renewable source of energy etc. Moreover, chemical fertilizers are becoming costlier input in agriculture. Thus, integrated nutrient management refers to the “maintenance of soil fertility and plant nutrient supply at an optimum level for sustaining the productivity through optimization of the benefits from all possible sources of organic, inorganic and biological compounds in an integrated approach.” Nitrogen plays a key role innutrition of the plants. As a matter of fact, the plant life would not be possible without this element. Adequate amount of nitrogen is also required to obtain good yield in vegetable crops. Phosphorous and potassium are considered as major nutrients in crops and they are involved in all the metabolic process in the plant and there is considerable evidence to show that, these element plays an important role in photosynthesis and helps in building up of carbohydrate in the plant. The production of dry matter is further affected by the effect of potassium on rate of respiration. Organic manures and biofertilizers are the important components of integrated nutrient management as supply the trace amounts of micronutrients which are generally not supplied by the farmers to their vegetable crops. Vermicompost is the product of ingested biomass by earthworm after undergoing physical, chemical and microbial transformations and available in the form of cast. Earthworm reduces the C: N ratio, increases humic acid, cation exchange capacity and water-soluble carbohydrates.
