Abstract: Pusa seed cum fertilizer disc drill includes a novel planting machinery and it is a tractor drawn mounted
An indigenous, improved and cost effective process for the preparation of fungicide, Mancozeb, a complex equipment utilizing a single or double disc opener assemblies and a torsion spring joints for connection of
compound of zinc with manganese ethylene bis dithiocarbamate in good yield (80 %) and purity (a.i. content the disc assembly to the frame. Disc assemblies are arranged alternately and spaced laterally from each
85 % ) is developed by reacting aqueous solutions of Nabam (Disodium ethylene bis dithiocarbamate) with other in two transverse rows supported for rotation about a horizontal axis offset at a acute angle from
manganese and zinc salts. The intermediate, Nabam (a.i. 90%) is prepared in aqueous solution by reacting transverse direction for opening a furrow. Fertilizer and seed boot assemblies are located adjacent the
carbon disulphide, ethylene diamine and sodium hydroxide. rearward facing convex side of the disc and includes a toe and tee scrapers. The users may adjust the
relative position of disc opener with respect to transport wheels by simply manipulating a lever. Fertilizers
and seed are dropped into the open trench by fertilizer and seed distributing means operated by two
transport wheels via pulleys, V- belts and over running clutches. The clutches compensates for wheel
slippage. Fertilizer and seed distributing means can be any proprietary items. The drill unit can include one
or more pivotable open center bevelled edge press wheels which can be mounted for pivotal movement
about the rear frame and which can be laterally spaced for proper placement of soil into covering relation
to the fertilizer and seed. Adjustable down pressure spring extending between press wheels hub and
vertical frame allow the press wheel to maintain ground contact and down pressure even when opener
blades encounter an obstacle thus improving germination of the seed. The torsion spring assemblies that
are prone to develop permanent deflection if seed drill is stored for a period of time. Parking stand are
provided to prevent such deformation.
