Abstract/ Executive Summary:

The experiment was conducted at the Regional Agricultural Research Station, Jamalpur during the rabi season of 2000-01 and 2001-02 to find out the optimum cutting times for obtaining maximum forage besides grain yield of barley (var. BARI Barly-1). Four treatments viz. no cutting (control); cutting at 40 DAE and grain production; cutting at 55 DAE and grain production; cutting at 40 + 55 DAE and then production were studied. It may be concluded from two year result that highest grain yield (2.39 t/ha) was obtained from no cutting but cutting at 40 DAE + grain production showed 29% lower yield with forage yield 8.61 t/ha.

Keywords: Barley, Fodder, cutting

Location: Jamalpur

Start Date: 25-11-2000

End Date: 26-03-2002

Program Area: Crop-Soil-Water Management

Commodity: Barley

Objectives:

To find out the optimum cutting times for obtaining maximum forage besides grain yield under AEZ 9

Methodology:

The experiment was conducted at the RARS, Jamalpur during the rabi season of 2000-01 & 2001-02. The experimental area was an irrigated medium highland of clay loam soil having PH value of 6.8 under Old Brahmpathra Floodplain AEZ 9. There were four treatments which were as: T1= No cutting (Control), T2= Cutting at 40 DAE + grain production, T3= Cutting at 55 DAE + grain production, T4= Cutting at 40 + 55 DAE + grain production. The experiment was laid out in a randomized complete block design with four replications. The unit plot size was 3m x 5m. The land was fertilized with 80-60-40 N, P₂O₅, K2O kg/ha through Urea, TSP and MP, respectively. Half of urea along with the entire amount of TSP and MP were applied one day before planting and were incorporated thoroughly by spading. The remaining urea was splited to every cutting followed by a light irrigation. The crop was irrigated at 20 days after sowing. Sowing was done in 20 cm row distance with continuous seeding on November 25, 2001. The variety BARI barley-1 was used. Cutting was done at 10 cm above the ground level. The green forage yield was taken plot wise after every cutting. Finally, the crop of no cutting treatment was harvested on March 16, 2002, cutting at 40 DAE treatments were on March 21, 2002 and the other two treatments were on March 29, 2002. The yield data were collected from 10 randomly selected plants prior to harvest from each plot. The grain and straw yield were obtained plot wise after harvest. The collected data were analyzed statistically and the means were separated as per LSD test.

Achievement/Findings:

Considering the total forage yield it was observed that the significantly highest fodder production (14.20 t/ha) was obtained from the single cutting at 55 days after emergence (DAE) which was statistically different from other treatments. The highest dry matter was produced by single cutting at 55 DAE (2.25 t/ha) which was statistically different from those of other two cuttings. The plant height was found significantly highest in cuttings at 40 + 55 DAE while the lowest was in 40 DAE cutting. The result revealed that plant population at initial stage (10 days after sowing) was not differed significantly due to treatment variation. But the number of spikes/m2 at harvest was found highest in the no cutting plot which at par to T2 treatments. The highest plant height was recorded in no cutting treatment which was similar to the cutting at 40 DAE. The treatment cutting at 55 DAE and cutting at 40+55 DAE produced shortest plant and were also identical to each other. The longest spike was recorded from no cutting treatment which was statistically differing from other treatments. Significantly highest number of spikelets/spike was found in no cutting treatment. The number of grains/spike was found highest in no cutting treatment which was statistically differing from other treatments. The highest 1000 grain weight was noted from no cutting treatment which was similar to cutting at 40 DAE. However, the highest grain yield was obtained from no cutting treatment (2.33 t/ha) mainly attributed for higher number of spikes/m2, number of grains/spike and 1000-grain weight. From the result it has been observed that for a single cut at 40 DAE only 29% grain yield was reduced compared to no cutting treatment. The similar trend of grain yield was also obtained in 2000-2001.
