Abstract


To study the impact of the subsurface placement of vermicompost manure on the root density, growth and yield of wheat (Triticum aestivum L. Var. UP 2526) the most important cereal crop in the Northern region of India, an experiment was conducted under field conditions in Mollisols soil at Honey Bee Research and Training Centre, G. B. Pant University of Agriculture and Technology Pantnagar by using Tractor Drawn Subsurface Manure and Seed Applicator which was designed in Farm Machinery and Power Engineering Department of the University. An experiment was conducted with five different treatments by the subsurface manure applicator machine on the field at different exposure lengths of rectangular orifice of manure hopper viz., control, ¼th, ½nd, ¾ th and full opening position. The exposure length of fluted roller seed metering device of the machine was fixed at 1/2nd opening position by a seed rate adjustable lever under all treatments for different forward speeds viz., 2, 4 and 6 km/h and the vermicompost having 31 % moisture content (d.b) was used in all treatments. The depth of placement of wheat was fixed 50 mm by tractor automatic draft and position control lever. The treatment T1 (100 % RDN) showed the best results due to providing maximum plant height, leaf area index, root length and yield of wheat crop. Thus, subsurface application of vermicompost is recommended for higher wheat production. Subsurface placement of vermicompost by the machine resulted in thrice benefits by increasing the wheat yield as well as reducing the application rate of vermicompost per hectare in the field and reducing the labour requirement.
