Leaf Colour chart-based nitrogen management-Impact on soil properties and nutrient uptake of short duration transplanted rice


Author(s): B Bhavana, P Laxminarayana, A Madhavi Latha and T Anjaiah

Abstract: A field experiment was conducted during Kharif, 2018 to study the effect of LCC based nitrogen management on growth of short duration transplanted rice. Treatments included two doses of nitrogen (120 and 150 kg ha-1) applied on basis of two critical LCC values- 3 and 4. In turn Nitrogen was applied in 3 equal splits @ 120 kg N ha-1 and (3 and 4) splits with half as basal, remaining @ 150 Kg ha-1. LCC based treatments were evaluated against control, recommended method and Farmers practice. Results revealed that, LCC -4 was more beneficial in enhancing yield and nutrient uptake of rice. Physico-chemical properties and nutrient status of soil were not unaffected by treatments. LCC-4 with 150 kg N ha-1 was superior in uptake of N, P and K (112.5, 46.8 and 115.2 kg ha-1 respectively). LCC based nitrogen application was effective in improving uptake of nutrients thus resulting in satisfactory yields.
