A Study on Agronomic and Soil Parameters to Develop a Walk Behind Engine Operated Weeder for Upland Crops
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
Weed control is a major problem in Indian agriculture and needs intensive efforts to mechanize the weeding operation. Weeds are serious threat to all crops. Weeding is an important but equally labour intensive agricultural operation. Delay and negligence in weeding operation affect the crop yield and in many cases cause complete crop failure. A study was conducted in farmer’s field at Tondamattur village of Coimbatore district, to study agronomic and soil parameters influencing development of walk behind engine operated weeder. The spacing of okra crop varied from 360 to 400 mm with an average value of 384 mm. Plant height of okra at15 DAS varied from 45 to 55 mm with an average value of 49 mm. The major weeds identified in the field were Acalypha indica, Echinochloa crus-galli, Echinochloa colona and Trianthema protulacastrum. The average pulling force of the weeds was observed to be 0.805, 1.036, 2.137 and 2.217 kgf for the identified weeds respectively. Moisture content of the soil was in the range 13 to 23.4 per cent (db) with an average value of 16.37 per cent (db). The bulk density of the soil was observed to be in the range of 1.08 to 1.56 g cm-3 with an average value of 1.348 g cm-3. The maximum and minimum values of cone index were 0.0432 and 0.1825 kg mm-2 with average value of 0.0962 kg mm-2.
