A field experiment was conducted at District Seed Farm (AB Block), Kalyani under Bidhan Chandra Krishi Viswavidyalaya during winter season of 2014-16in upland situation to study the effect of date of sowing on the growth and yield of wheat genotypes with an objective to optimize row spacing for yield maximization in wheat genotypes. The experiment was carried out in a split plot design with three wheat genotypes (HD 2977, DBW 103, K 0307, HD 2733 and DBW 39) and three row arrangements (15, 18 and 21 cm) and experiment was replicated thrice. Amongst various tested cultivars, highest LAI at 50 and 65 DAS was registered with the HD 2967 and K 0307, respectively. Both are at par to each other and significantly superior to other set of treatments. Statistically more number of tillers/m2 was observed with the HD 2967 and showed parity with the HD 2733. Number of tillers/m2 maximum observed with 18 cm and significantly better to rest of the assorted units. Further, days to 50% heading least observed with the 21 cm row spacing, and significantly superior to other treatments. Moreover, days to physiological maturity took least time with the 15 cm spacing and statistically better to other set of treatments. Grains per ear head was highest registered with the DBW 39 and showed parity with the K0307, and significantly better to other treatments. Test weight failed to produce any significant response. Highest grain yield was registered with the HD 2967 (3.79 t/ha), and was at par with the DBW 39 (3.41 t/ha) and K0307 (3.21 t/ha), and statistically better to rest of the treatments combination. More straw yield was observed with HD 2967 (5.94 t/ha) and was at par with DBW 39 (5.41 t/ha). With various subplot treatments, maximum grain and straw yield was observed with the 18 cm (3.53 and 6.03 t/ha), and showed parity with 15 cm row spacing (3.21 and 5.87 t/ha). Highest B: C ratio recorded with the HD 2967 (1.70) with row spacing of 18 cm (1.64).
