Author(s): Uma Maheswari M and P Murali Arthanari
Abstract: The aim of the investigation was to study the impact of corn flour application on nutrient uptake of organic brinjal and nutrient removal by weeds. The treatments comprised of different non chemical weed management practices viz., Live mulching with sunnhemp after 30 days of growth (T1); Application of Corn Flour @ 1 ton ha-1 on 3 DAT (T2); Application of Corn Flour @ 1 ton ha-1 on 3 DAT + HW at 60 DAT (T3); Live mulching with Multi Varietal crops (Navathaniam) after 30 days of growth (T4); Application of sunflower dried stalk extract on w/v basis @ 1:10 lit ha-1 on 3 DAT (T5); Application of sunflower dried stalk extract on w/v basis @ 1:10 lit ha-1 on 3 DAT + HW at 60 DAT (T6); Mechanical weeding twice using twin hoe weeder on 30 and 60 DAT (T7); Hand Weeding on 30 and 60 DAT (T8); Weed free check (T9); and Unweeded control (T10). Results indicated higher nutrient uptake (81.0, 11.7 and 47.4 kg N, P2O5 and K2O ha-1) in crops in the treatment which was subjected to Application of Corn Flour @ 1 ton ha-1 on 3 DAT + HW at 60 DAT. Application of sunflower dried stalk extract on w/v basis @ 1:10 lit ha-1 on 3 DAT + HW at 60 DAT (73.2, 10.7 and 43.5 kg N, P2O5 and K2O ha-1) was next best treatment. Positive response of crop yield to nutrient uptake and negative response to weed nutrient drain was observed.
