Abstract

Wheat is more sensitive toward climate change. Reasing temperature causing yield reduction specially in late sown wheat. Consider this fact a field experiment was conducted during rabi seasons of 2017-18 and 2018-19 at Agronomical research farm, Acharya Narendra Deva University of Agriculture and Technology, Ayodhya, India, to study on agro-meteorological indices, grain and straw yields and their relationships with each other, the experiment comprised of four sowing methods viz. broadcasting sowing (Bs), line sowing (Ls), furrow irrigation ridge bed (FIRB) and criss cross sowing (20 × 20 cm) (Cs) in main plot and five nitrogen managements treatments viz., control (N0), 50% N as basal + 25% N after first irrigation + 25% N after second irrigation (N1), 50% N as basal + 50 % N after first irrigation (N2), 25% N as basal + 25% N after second irrigation + 50% through FYM as basal (N3), 25% N as basal + 75% through FYM as basal (N4) was laid out with three replication. The agro-meteorologi

Keywords

Wheat, sowing methods, nitrogen, agro-meteorological indices, yield.

Conclusion

The above findings concluded that higher yield, accumulated heat units, HTU, and heat use efficiency were recorded with FIRB. Among the nitrogen management, N1 recorded higher yield, GDD, HTU, and heat use efficiency. It indicated that sowing methods and nitrogen management responded positively to yield, GDD, HTU, and heat use efficiency. Besides, application of agro-meteorological indices provides the evidence correlated to effect of temperature and solar radiation on the crop phenology, yield and heat energy consumption in wheat crop.
