The experiment was started in 2018-2019 period at the field of Regional Agricultural Research Station (RARS) under Jamalpur district in Bangladesh. Before initiation the experiment, the soil samples were collected from a depth of 0-20 cm for each replication and analyzed following standard methods. The chemical properties of soils in the experimental site was silt clay loam in texture belonging to Sonalata series under Agro-Ecological Zone-8 (AEZ-8), 24?56´11´´N latitude and 89?55´54´´E longitude and an altitude of 16.46m. Nutrient status of initial soil prior to fertilization is presented.
The experiment was laid out in Randomized Complete Block (RCB) design with six treatments replicated thrice. The unit plot size was 1. 2m x 2.4 m. There were six treatments viz. T1 = 100% RDCF of garlic + 0% RDCF of coriander, T2 = T1 + 10% RDCF of coriander, T3 = T1 + 20% RDCF of coriander, T4 = T1 + 30% RDCF of coriander, T5 = T1 + 40% RDCF of coriander, T6 = T1 + 50% RDCF of coriander,
The seeds of garlic (var. BARI Rasun–1) and coriander (var. BARI Dhania–1) were sown on 14 November, 2019 spacing for garlic was 10 cm 10 cm. Nitrogen, phosphorus, potassium, sulphur, zinc and boron were used in the form of urea, TSP, MoP, gypsum, zinc sulphate and boric acid, respectively. All P, K, S, Zn, B and 1/3rd urea-N were applied at the time of final land preparation and the remaining 2/3rd urea-N was applied in two equal installments at 30 and 50 days of sowing. First time sowing coriander was harvested at 40 days after sowing (DAS) and second time sowing of coriander was harvested at 45 days after sowing (DAS). All the intercultural operations such as irrigation, weeding, insect control etc. were done as and when necessary.
Garlic was harvested on 25 March, 2020. Bulb yield was calculated in ton per hectare considering the whole plot as harvested area. Ten plants of garlic from each plot were selected randomly to collect data on yield components. Data on yield and yield contributing characters were recorded and analyzed statistically using statistical software STAR which was developed by IRRI. The Garlic Equivalent Yield (GEY) was calculated by using formula given by Ahlawat and Sharma (1993), as follows – GEY = {Yield of each crop (t ha -1) / Price of garlic (Tk. t-1)} x {Economic value of each crop (Tk. t-1)}.
