Abstract
The study entitle “Temporal and spatial management for higher productivity of barley (Hordeum vulgare L.) under changing climate scenario”. was conducted with the following objectives: (i) To find out the optimum seed rate and row spacing for barley under different sowing dates. (ii) To study the growth, yield and quality of barley under different agronomic practices. (iii) To study the nutrient and soil moisture extraction by barley under different agronomic management practices. (iv) To work out the economics of different treatments.
The present study was conducted at the Regional Research Station (Bawal) of CCS Haryana Agricultural University, Hisar during the year 2015-16 and 2016-17. The experiment was conducted in split-split plot design with three replications. Treatments consisted of four dates of sowing viz., D1 (last week of October), D2 (1st week of November), D3 (2nd week of November) and D4 (3rd week of November) and two seed rates viz., recommended and 110 % of recommended were kept as main plot and three row spacings viz., 17.5 cm, 20 cm and 22.5 cm (recommended) as sub plot.
The results of study revealed that all the Phenological, Growth and Physiological parameters; Yield and its attributes; Quality and Nutrient parameters, Water Use Efficiency and Net returns were significantly superior under D1 (last week of October), followed by D2, D3 and D4 in descending order except malt content sown crop under changing agro-climatic conditions of Haryana.
Increasing seed rate from S1 @ 87.5 kg/ha to S2 @ 96.5 kg/ha had no significant effect on the above cited parameters under study.
Row spacing 20 cm (R2) was found optimum than other spacings 17.5 cm (R1) and 22.5 cm (R3) and R2 had higher values of all the parameters.
For achieving consistently higher grain yield and net returns from barley under changing climate, it should be sown between last week of October to 1st week of November with seed rate of 87.5 kg/ha and at a row spacing of 20 cm.
