Soil Test Based Fertilizer Prescriptions under Integrated Plant Nutrient Supply for Hybrid Rice (cv. US – 382) in Alluvial Soils of Jorhat District of Assam

Study on Integrated Effect of Inorganic Fertilizers and Organic Manure on Available Nutrients, Yield and Nutrient Uptake in Scented Rice

“…In gradient III, the highest value is observed which might be due to better assimilation of nutrients by the crop which resulted in luxuriant crop growth with higher grain formation. Similar findings were also reported by Kadam and Sonar [7][8][9] and Kashyap et al [10] in rice.…”

“…Due to combined application of vermicompost and inorganic fertilizer, the CEC of the soil might have improved and increased the retention of K in exchangeable form by reducing its fixation. Similar findings were recorded by Gogoi et al [23] Basumatary et al [12] and Kashyap et al [10].…”

“…This increase in availability of nutrients and organic carbon could be ascribed to graded dose of fertilizer application in order to create fertility gradient in the same field. Similar findings were reported by Chatterjee et al [11] Basumatary et al [12] Ahmed et al [13] and Kashyap et al [10] 3.2 Test Crop Experiment…”

“…Due to possible favourable effect of combined application of fertilizers on soil environment, better performance, better root proliferation, higher amount of nutrient uptake was observed. Similar increase in nutrient uptake by rice due to application of organic and inorganic fertilizers in acid soils of Assam was recorded by Singh et al [18], Basuamatary et al [12] Das et al [9] and Kashyap et al [10].…”

“…With increased addition of NPK fertilizers, the root and shoot growth obviously got improved which in turn led to higher production of biomass resulting in higher organic carbon content in soil as observed by Babhulkar et al [24]. These results are also supported by the findings of Basuamatary et al [12] Das et al [9] and Kashyap et al [10] in soils of Assam.…”
