The main objective of the Seed Production Department is to produce sufficient quantity of high quality seed for farmers. During the year, 1,516.1 tonnes (23,822 bags of 140 lbs) of seed consisting of 12 commercial varieties were produced (see table below). These seeds were distributed to farmers across the country.
During the year, approximately twenty four percent of the varieties grown consisted of the G98 varieties, while the others grown were 1.0% GRDB 9, 34.0% GRDB 10, 5.9% GRDB 11, 11.4% GRDB 12, 1.0% Aromatic, 20.4%, GRDB 14, 1.9% Rustic, and 0.6% IR-22. An additional 18.2 tonnes (285.9 bags) were also harvested from experimental plots and sold as grains.

Based on the graph above, seeds of variety GRDB 10 was the most dominant produced, followed by GRDB 14, G 98-196 and GRDB 12. Varieties G 98 30-3 and GRDB 11 were the others where more than a thousand bags of seeds were produced for the calendar year. Seeds produced from other varieties mentioned were below that of GRDB 11 of which IR-22 was the least in terms of the number of bags of seeds produced.
Land preparation for the spring crop included 1st, 2nd and 3rd roam on a total of 440.9, 453.5 and 44.8 acres respectively while 400.8 and 354.1 acres received 1st and 2nd chip. Further, 12.56 acres received disc ploughing. Final land preparation (rake and leveling) was done on 354.1 acres. In addition, 260.11 acres received dry land leveling.
For the Autumn Crop 1st and 2nd roam accounted for 453.0 and 323.94 acres respectively. In addition, 453.5 acres received 1st and 2nd chip respectively, while 3rd chip was done on 158.9 acres. Final land preparation (rake and leveling) was done on 453.5 acres. Additionally, 107.3 acres received dry land leveling.
The most dominant variety sown during 2015 was GRDB 10 while the least sown was IR-22.
Fertilizer application was based on soil test recommendations in which balance nutrition fertilizers and micro-nutrients were applied in both crops. During the Spring Crop 8:32:16 and 6:25:25 were incorporated on a total of 187.5 and 158.01 acres respectively. In addition, micro-nutrients Boron and Zinc Chelate were applied on 345.51 and 90.05 acres respectively. In the Autumn Crop 8:32:16 and 6:25:25 were applied on 166.64 and 202.0 acres while 368.64 and 69.39 acres received Boron and Zinc Chelate respectively. Urea was applied in two splits for both crops using two bags per acre.
