INFLUENCE OF SEED SOURCE AND STORAGE CONDITION ON GROWTH AND YIELD OF WHEAT

Abstract

An experiment was conducted at the Agronomy laboratory with storing wheat seed and subsequent study in Agronomy field ofSher-e-Bangla Agricultural University, Dhaka during May 2011 to March 2012 to find out the influence of different storage conditionson wheat seed and to evaluate on different seed source of the growth and yield performance of stored seeds. The experiment was carried out in randomized complete block design with two factors comprising three seed source viz.,i) S 1 = BARI seed, ii) S = BADCseed and iii)S 3 =Farmer seed, and four storage conditionslike i) C 1 2 = Below 10 = Below 20 0 C iii) C 3 = Polybag (room temperature) iv) C =Tin container (room temperature) having three replications. Result showed that seed source, storage condition of seed and their combinations had significant effect on yield and harvest indexof wheat.BARI seed showed the highest grain yield (3.48 t ha 4 ), straw yield (5.21 t ha −1 ) and biological yield (8.69t ha −1 ). Seed storedbelow 10 0 C condition showed the highest grain yield (3.29 t ha −1 ), straw yield (5.26 t ha −1 )and biological yield (8.55 t ha −1 ). Combination of S (BADC seed×below20 0 C) showed the highest number of tillers m -1 at 60DAS (97.87) and 75DAS (112.50). On the other hand, combination of S (BARI

2 ×C 1 0 C ii) C 2 ×C 1 2 −1 seed×below10 0 C) gave the highest filled grains spike −1 (40.25), 1000-grain weight (43.92 g), grain yield (3.67 t ha −1 ),straw yield (5.57 t ha ) and biological yield (9.24 t ha −1 ). Farmers seed was found poor from its yield point of view, even either any storage conditions could not improve its status.
