Abstract
A field trail was conducted near Sutlej river at village Khaira, District Ludhiana (Punjab) India during the Rabi season of 1993-94, to study the ‘Production potential of poplar-wheat based agroforestry system in relation to wheat varieties and their dates of sowing’. Ten varieties of wheat with five dates of sowing were sown for inter cultivation under poplar (Populus deltoids) clone G-48 spaced at 4.8 x 4.8 metre, planted in February, 1990.
The results indicated that highest grain yield of wheat was observed in PBW-226 cultivar over different dates of sowing, although its grain yield was at par with other wheat cultivars, viz., WH-542, HD-2285, HD-2329, PBW-154 and PBW-299. Poor performance was noticed in case of CPAN-3004 and WL-1562.
Dates of sowing influenced the grain yield of wheat significantly. Maximum grain yield (27.82 q/ha) was recorded when wheat crop was sown on November 3. Thereafter grain yields were significantly reduced by 23.71, 50.29 and 74.65 per cent where sowing of wheat was delayed to November 18, December 3, December 18, respectively.
