ABSTRACT
An experiment was conducted on nutrient uptake of rice as influenced by methods of cultivation and micronutrient management practices during kharif 2014. SRI method recorded the higher Nitrogen(N), Phosphorus (P) uptake in grain (116.96 kg ha-1 and 6.98 kg ha-1 respectively) and straw (102.52 and 4.05 kg ha-1 respectively) and also total uptake of N and P. Potassium uptake in grain (12.17 kg ha-1), straw (81.48 kg ha-1) and total (93.64 kg ha-1) with the aerobic method. The treatment S4 (Seed treatment combined with foliar spray of ZnSO4 and FeSO4 at 0.5% each at boot leaf stage and panicle inititation stage) recorded significantly higher N uptake (125.37kg ha-1) and total N and P uptake in grain. However, soil application of ZnSO4 at 20 kg ha-1 and FeSO4 at 10 kg ha-1 recorded significantly higher K uptake in grain (71.38 kg ha-1). It also recorded significantly higher N and P uptake in straw. Zn uptake in grain (40g ha-1) was recorded high in Conventional method and Zn uptake in straw and total Zn uptake (252.50g ha-1 and 290g ha-1 respectively) with SRI method. Fe uptake in straw, grain and total was 792.92, 3465 and 4185.41g ha-1 respectively with the Conventional method. Seed treatment combined with foliar spray of ZnSO4 and FeSO4 at 0.5 percent each at boot leaf stage and panicle inititation stage recorded significantly higher grain Zn and Fe uptake (41.66 and 1075g ha-1, repectively). Also the experiment revealed that there was a higher uptake of straw Zn and Fe (440 and 4315.00g ha-1, respectively) and Total uptake of Zn and Fe.
Key words: Aerobic rice, Seed treatment, Nutrient uptake, Foliar nutrition.
