High Protein Rice (CR Dhan 310):

National Rice Research Institute, Cuttack has developed a high protein rice variety CR

Dhan 310 with an average 10.3% protein in milled rice, by improving the popular high yielding

variety Naveen. It is now released by the Central Variety Release Committee. Rice is one of the

most important staple foods, particularly for the Asians, but it is generally low in grain protein

content (6-8%), which is the lowest among cereals. Hence, protein malnutrition in poor

population for whom rice is staple food is a serious nutritional problem. The research on

developing the high protein rice started, when the ICAR-National Rice Research Institute,

Cuttack identified one accession (ARC10075) from Assam Rice Collection as high grain protein

content (GPC) donor and used in three repeated backcrossing with recurrent parent, Naveen

followed by generation advancement and selection for identification of introgression lines. Ten

high yielding introgression lines were grown in the same experimental plot at the experimental

farm of the National Rice Research Institute in rabi 2014 and kharif 2014 under standard

agronomic package and practices. All lines had significantly higher GPC and protein yield than

their corresponding high yielding parent with acceptable grain quality. Among these lines, CR

Dhan 310 (IET 24780) was identified as high protein rice variety with an average GPC of 10.3%

in milled rice in multi-locational testing (under AICRIP-Biofortification trial).

cheap and easy to use handy tool provided with a folder having N application schedule. By using

this, farmers can adjust the N application to actual crop demand, achieve higher yields and

reduce the N application by 10-20 kg/ha.

Urea briquette applicators:

Two Row Urea Briquette Applicator:

It is manually pulled two row urea briquette applicator. It consists of two boxes, frame,

two cup type metering roller, one axle, one ground wheel and one handle fitted in the frame. It is

for basal application also. The removable furrow openers were fitted for both rows. The furrow

opens by furrow openers closes immediately by float after placement of urea briquette. During

application the skids work in the middle of alternate plant rows, leaving the middle row without

application for the operator to walk in that row. This process distributes briquettes evenly

between plant rows and two rows share the banded fertilizer.

application. The removable furrow openers were fitted for all rows. Two ground wheels support

applicator from both ends and four cup in metering unit gives the uniform placement of urea

briquettes.

working of applicator is similar to drum seeder. Operator has to pull the applicator so the urea

briquettes filled in the drums dropped on field in a uniform manner. Two ground wheels support

the applicator from both ends and float gives easy movement in puddled field condition.

Conoweeder with Urea Briquette Applicator

It is attachment behind the conoweeder to apply urea briquettes simultaneously with

weeding operation. It consists of two cones, one float, one briquette hopper, briquette delivery

control system, and one handle fitted in the frame. It is made by using material angle Iron, GI

sheet, MS flat etc. The machine is useful for weeding between rows of wet land paddy crop and

urea briquette application. The working of applicator is similar to conoweeder, operator has to

push the weeder and at same time at some interval push the clutch fitted on the handle to place

one or two urea briquettes at a time. The efficiency of the urea briquette placement is depending

on the operators ability to give forward and backward movement for weeding and at the same

time push the clutch for dropping of urea briquettes.
