Description The present experiment entitled “Response of dual-purpose oat to cutting management and
fertility levels”was conducted at Research Farm of Forage section, Department of Genetics and Plant
breeding, CCS Haryana Agriculture University, Hisar during rabi season of 2012-13 with the objective
to study the best time of cutting of oat in relation to fodder cum grain yield and optimum fertility level
for fodder and grain production.
3 different treatments on cutting management for fodder i.e C50, C60 and C70 and 4 treatments
on fertility levels i.e control, 40 kg N + 20 kg P2O5, 80 kg N + 40 kg P2O5 and 120 kg N + 60 kg
P2O5/ha were taken in Factorial Randomised Block Design with 3 replications.
Plant height, green and dry matter production per metre row length and green fodder yield
increased significantly with each delay in fodder harvesting from 50 DAS upto 70 DAS. Crude protein
and IVDMD content in fodder decreased significantly with delayed cuttings. The green and dry matter
production per metre row length and green fodder yield increased significantly with increasing levels
of fertility. Crude protein content in fodder, grain and straw were found to increase due to increase in
fertility levels. The yield attributing characters i.e number of panicles per metre and spikelets per
panicle were found to be non significant under various cutting management treatments. With increase
in fertility levels there was increase in number of panicles and spikelets upto C70 treatment. Number of
grains per panicle were found highest under C50 and maximum test weight was recorded under C60. The
grain yield was found to be highest when oat was cut for fodder at 60 DAS and then left for grain
production. However straw yield was recorded maximum under C50 treatment.
The highest net returns (23,724 Rs/ha) were recorded under C60 treatment and the highest net
returns (27,713 Rs/ha) under F3 treatment i.e 120 kg N + 60 kg P2O5/ha. The optimum dose of N +
P2O5 could not be worked out as there was linear response from FO to F3 level of fertility.
