Abstract/ Executive Summary:

The aforesaid results of two locations indicated that seed rate had significant effect on yield in field pea. The highest pod yield of 5.13 t ha^-1 and 4.98 t ha^-1 was obtained from using 100 kg seed ha^-1 at Jamalpur and Ishurdi, respectively which showed statistically similar results obtained from using 80 and 90 kg seed ha^-1 at Jamalpur 90 kg ha^-1 at Ishurdi. In conclusion, 90- 100 kg seed ha^-1 can be recommended for extensive cultivation of field pea as a relay crop with T. Aman rice. Though walkway facilities did not show any significant variation in pod yield but walk way it can be recommended for easy and smart-picking of green pod without damaging the crop.

Keywords: Seed rate, Walking way, Relay cropping, Field pea

Location: At Pulses Research Centre (PRC), Ishurdi, Pabna and Regional Agricultural Research Station (RARS), Jamalpur

Start Date: 00-11-2012

End Date: 00-05-2013

Program Area: Crop-Soil-Water Management

Commodity: Fieldpea

Objectives:

The experiment was conducted to find out the optimum seed rate and walkway for easily harvest of green pod for vegetable and forage without damaging of plants and immature pod under relay cropping with T. Aman rice to achieve higher yield

Methodology:

The study was conducted at Pulses Research Centre (PRC), Ishurdi, Pabna, and Regional Agricultural Research Station (RARS), Jamalpur belongs to (AEZ-11) and (AEZ-9) respectively under Bangladesh Agricultural Research Institute (BARI), during rabi 2012-2013 to select suitable management practices viz. seed rate and walking way for the convenient of pod picking on yield of field pea var. Natore local as relay cropping with T. Aman rice which was found promising for green pod production through earlier screening program. The geographic coordinates of the research studied areas were located between 24.15° north latitude and 89.0° east longitude and 24034’ and 25026’ north latitude and between 89040’ and 90012’ east longitude respectively. The six seed rates S1=50, S2 =60, S3 =70, S4 =80, S5 =90, S6 =100 kg ha^-1 and two walking way viz. W1=15 cm walking way was maintained after 2 m interval in the plot and W2 =control were used as a treatment. Considering the over location the unit plot size was maintained by 5m x× 4 m. The experiment was conducted under Randomized Complete Block design with three replications for both the locations. Seeds were soaked into water over a night to ensure the optimum germination prior to sowing. As per seed rate seeds were sown as relay cropping in the existing rice field before 15 days of rice harvest on 15 November, 2012 at Ishurdi and 29 October, 2012 at Jamalpur location. During seed sowing 15 cm walking way was maintained apart two meter in a plot. T. Aman was harvested leaving 30 cm straw height from ground level. No weeding was done during the whole crop growing period. Once a light irrigation (1 cm) was applied at 35 DAE for better crop establishment at Jamalpur location only. Pods were harvested at different dated on the basis of pod maturity as a green pod. Ten plants were selected randomly from each plot before harvest of crop to record data on yield attributes while pod yield was collected on the whole plot basis at different day’s interval when bearing pod was matured as a green pod. Weight of fresh green pod obtained from the different harvests were recorded and summed up at the end of the crops life and converted into t ha^-1. Collected data were analyzed statistically following the ANOVA technique with the help of MSTAT-C software and mean separation was done as per LSD test according to Gomez and Gomez (1984). Variable cost of cultivation, gross margin and BCR were calculated considering the wages of local labour and input (seed) prices and selling prices of seed at the harvesting time. Economic analysis was done in terms of total cost of cultivation, net return and BCR. Benefit cost ratio was calculated by using f formula.

The aforesaid results of two locations indicated that seed rate had significant effect on yield in field pea. The highest pod yield of 5.13 t ha^-1 and 4.98 t ha^-1 was obtained from using 100 kg seed ha^-1at Jamalpur and Ishurdi, respectively which showed statistically similar results obtained from using 80 and 90 kg seed ha^-1 at Jamalpur 90 kg ha^-1 at Ishurdi. In conclusion, 90- 100 kg seed ha^-1 can be recommended for extensive cultivation of field pea as a relay crop with T. Aman rice. Though walkway facilities did not show any significant variation in pod yield but walk way it can be recommended for easy and smart-picking of green pod without damaging the crop.
