“…On the other hand, the timely sown crop gets an advantage because after having completed its vegetative growth satisfactory it comes in the ear stage when the temperature is quite favourable. Deshmukh et al [37] and Bashir et al [38] also reported similar findings and stated that timely sowing gave higher test weight as compared to delayed sowing. Yields of wheat increased significantly when sowing of wheat on 15 th November which was statistically at par with sowing on 30 th November (Table 1.).…”

Present experiment was conducted during Rabi season 2016-17 and 2017-18 at Research farm, Rajasthan Agricultural Research Institute, Sri Karan Narendra Agriculture University, Durgapura, Jobner, Rajasthan to find out the response of wheat cultivars to irrigation scheduling under different sowing dates. Thirty-six treatment combinations were investigated. Treatments comprises four irrigation levels: I1 (0.6 Etc), I2 (0.8 Etc), I3 (1.0 Etc) and I4 (1.2 Etc), three cultivars: C1 (Raj-4120), C2 (Raj-4079) and C3 (Raj-4238) and three dates of sowing: D1 (15th Nov.), D2 (30th Nov.) and D3 (15th Dec.) in split plot design. A critical examination of results showed that irrigation applied at 1.2 Etc (I4) recorded the maximum values of yield parameters (effective tiller per metre row length, number of grains per spike, length of spike per spike, spikes per metre square area and test weight) and yields. Further results on cultivar indicated that the Raj 4079 proved significantly superior over Raj 4120 and Raj 4238 with respect to all yield attributes. However, results showed that sowing of wheat on 15th November gave higher values for yield attributes and yield.

: A field experiment was conducted on loamy sand soil at the Agronomy Instructional Farm, S. D. Agricultural University, Sardarkrushinagar to study the response of bread wheat (Triticum aestivum L.) and durum wheat (Triticum durum Desf.) genotypes to different sowing time in North Gujarat Agro-climatic conditions during Rabi season of the year 2008-09.The treatment consisted of four sowing times i.e., 10 th November (early), 25 th November (timely), 10 th December (late) and 25 th December (very late) and four wheat varieties (viz., GW 322, GW 496, GW 173 and GW 1139). The results of experiment revealed that the plant population at initial and harvest, test weight, harvest index were remained unaffected due to different sowing times. Plant height of wheat genotypes increased remarkably higher under10 th and 25 th November sowing. While, days to 50 per cent heading and days to physiological maturity were noticed significantly higher up from 10 th November to 10 th December sowing times. The values of number of spikes per meter -2 (292 to 304), length of spike (7.41 to 7.83 cm) and number of grains per spike (40.86 to 43.88) was noticed higher upto 10 th December sowing times. Remarkably, the higher grain yield kg ha -1 was produced when wheat crop sown from 10 th and 25 th November (4000 to 4200 grain kg ha -1 ) and in case of straw yield upto 10 th December was found ideal. Increase in grain yield (kg ha -1 ) was 5.00, 6.84 and 25.24 per cent as well as 4.27, 3.82 and 16.16 in straw yield (kg ha -1 ) higher as compared to early, late and very late (10 th November, 10 th December and 25 th December) sowing times. The result of mean data of varieties indicated that the different growth parameters viz., plant height, days to 50 per cent heading, days to physiological maturity were significantly influenced and maximum values of these parameters were recorded by wheat variety GW 322. However, plant population at initial and harvest, harvest index and protein content were remained unaffected due to different varieties. Significantly higher values of yield attributes viz., number of spikes per meter -2 (305), length of spike (8.12 cm) and number of grains per spike (42.24) were observed in variety GW 322 while, test weight was recorded significantly higher by variety GW 1139. The wheat variety GW 322 produced significantly higher grain yield 4137 kg ha -1 and straw yield 6338 kg ha -1 which was increased by 4.84, 3.49 and 21.51 per cent higher over varieties GW 496, GW 173 and GW 1139, respectively.
