INM in Vegetable crops .pptx
The document discusses integrated nutrient management in vegetable crops. Integrated nutrient management aims to combine organic, inorganic and biological sources of nutrients to sustainably increase crop productivity while preserving soil productivity. It involves maintaining optimal plant nutrient levels through proper combinations of fertilizers, manures, crop residues, nitrogen fixing crops and biofertilizers suited to the ecological and economic conditions. The goals are to maintain soil productivity, ensure sustainable agriculture, reduce input costs and prevent environmental degradation.

- 1. INTEGRATED NUTRIENT MANAGEMENT INVEGETABLE CROPS
- 2. Integrated nutrient managementmeans combined application of different sources of plant nutrients like organic inorganic and bio fertilisers for sustainable crop production without degrading the natural resources on long term basis . The objective or aim to integrate the use of natural and man made soil nutrients to increase crop productivity and preserve soil productivity for future generation .
- 3. ▸ INM involvesmaintenance or adjustment of plant nutrient supply to an optimum level for sustaining the desired crop productivity. ▸ It involves proper combination of chemical fertilizers, organic manures, crop residues, nitrogen fixing crops and bio-fertilizers suitable to the system of land use and ecological, social and economic conditions. WHY INM? •Unbalanced use of N:P:K have caused deleterious long term effects on soil fertility and productivity. •In intensive cultivation, application of mere chemical fertilizers (N:P:K) Not sufficient for sustaining the yields Leads to deficiency in the soil for secondary nutrients and Deficiency of micro-nutrients in the soil which limit crop productivity •Use of organic manures, green manures, crop residue and biodegradable rural and urban waste •Supplement the major nutrients. •Increase the efficiency in other nutrients supply •Leading to improvement in physical and biological properties of the soil
- 4. GOALS OF INM To maintain soil productivity To ensure productive and sustainable agriculture To reduce expenditure on cost of purchased inputs by using farm manure and crop residues etc. To utilize the potential benefits of green manures, leguminous crops and bio-fertilizers To prevent degradation of the environment To meet the social and economic aspirations of the farmers without harming the natural resource base of the agricultural production PRINCIPLES OF INM In the soil, replenishment of chemicals removed by the crop Maintenance of organic matter content in the soil Avoidance of weeds, pests and diseases occurrence Control of soil acidity and toxicity Control of soil erosion by improving soil physical properties

Improves & sustain Physical, Chemical and biological functioning of soil. • Balanced nutrition - Balanced nutrition to the crops, better nutritional uptake and hence better plant growth and yield • Nutrient demand - Enhance the availability of nutrient. Improvement in the organic matter content in the soil - Inorganic sources insufficient for nutritional needs. - • Multiple nutrient deficiency - Maintenance of soil nutrients reserve. Minimize antagonistic effects of nutrient imbalance. • Pollution. - Reduced use of chemical fertilizers , reduce nutrient losses , reduces pollution of ground water and environment. • Use of available nutrient sources for sustainable agriculture - • Enhance crop yield & improve produce's quality appearance, taste and nutritional richness. • Fruitful utilization of farm wastes, organic sources are cheaply available minimize production cost & residual effect remains beneficial to succeeding crops.
