Abstract/ Executive Summary:

The experiment was conducted to find out a suitable intercrop combination of Bilatidhonia and winter pumpkin relayed with different summer cucurbits (Bilatidhonia + winter pumpkin)/summer cucurbits) in the hill valley of the Agricultural Research Station (ARS), Raikhali, Rangamati during 2003-04 and 2004-05. The results revealed that all the intercrop combinations gave the highest fresh yield of Bilatidhonia than that of the sole Bilatidhonia with an exception of Bilatidhonia + winter pumpkin followed by ash gourd and summer pumpkin combination. Maximum fresh yield of Bilatidhonia (50.13 t/ha) was recorded from Bilatidhonia + winter pumpkin closely followed by ribbed gourd and bitter gourd (50.00 t/ha) combination which showed 15- 15.5% higher than that of sole Bilatidhona. Summer cucurbits relayed with Bilatidhonia after harvesting of winter pumpkin gave reasonable good yield where ribbed gourd produced the highest yield (15.29 t/ha). Winter pumpkin intercropped with Bilatidhonia also produced reasonable good yield ranging from 31.88 to 32.68 t/ha compared to the sole winter pumpkin. The highest Bilatidhonia equivalent (69.02 t/ha) and gross return (Tk. 103535440/ha) were obtained from (Bilatidhonia + winter pumpkin)/ bitter gourd or ribbed gourd combination. But intercropped Bilatidhonia with winter pumpkin relayed by ribbed gourd gave the highest gross margin (Tk. 859, 566/ha) with maximum benefit-cost ratio (4.90) at hilly area of Raikhali, Rangamati.

Commodity: Vegetables, Pumpkin, Coriander

Objectives:

To find out the productivity and profitability of Bilatidhonia -winter pumpkin intercropping system relayed with summer cucurbits in different combinations in the hilly region.

Methodology:

The experiment was conducted at the Agricultural Research Station (ARS), Raikhali in the district of Rangamati during two consecutive years of 2003-04 and 2004-05. The soil of the experimental plot was sandy clay loam having pH of 5.7. The total rainfall of 2004-05 was more than that of 2003-04. From November to February, there was no rainfall during both the years. The experiment was laid out in randomized complete clock design with 3 replications. The unit plot size was 3.0 m x 3.8 m consisting of 3 small plots, each measuring 3 m x 1 m with 40 cm distance between two small plots. The unit plot was subdivided into small plots for easy preparation of plot to get good tilth of soil like vegetable seedbed that provided better germination of seeds. It was also done for better cultural management as well as for the convenience of irrigation and drainage of excess water. Seven different intercrop combinations, such as T₁= (Bilatidhonia + winter pumpkin/ash gourd), T₂= (Bilatidhonia + winter pumpkin/bitter gourd), T₃= (Bilatidhonia + winter pumpkin/ribbed gourd), T₄= (Bilatidhonia + winter pumpkin/snake gourd), T₅ = (Bilatidhonia + winter pumpkin/summer pumpkin), and T₆ = Sole Bilatidhonia and T₇= Sole winter pumpkin were taken in this study. Seeds of Bilatidhonia were broadcasted @ 40 kg/ha on finely prepared bed on 7 November and 10 in 2003 and 2004, respectively. Four holes were made to sow local winter pumpkin seeds at every corner of the Bilatidhonia plot (3.0 m x 3.8 m) and 6 seeds were dibbled per hole on the same date of Bilatidhonia sowing. After 15 days of dibbling, four seedlings are allowed to grow. Seeds of different local cultivars of summer cucurbits (ash gourd, bitter gourd, ribbed gourd, snake gourd and summer pumpkin) were sown into the same pit of winter pumpkin following the same principles at the last week of March after the harvest of winter pumpkin. Bilatidhonia sole crop was fertilized @ 10 tons cowdung/ha and 160-70-100 kg of N,P₂O₅ and K₂O/ha, respectively. N, P₂O₅ and K₂O were used in the form of urea, triple supper phosphate (TSP) and muriate of potash (MP). Bilatidhonia was harvested from 04 February (90 DAS) to 30 July at an interval of 25 days, winter pumpkin was harvested from January to 15 March in each year. Harvests of summer cucurbits were started on 10 June and continued upto 31 July. The yield attributes of Bilatidhonia, such as plant height, number of leaves per plant, leaf size (leaf length and leaf breadth), fresh weight of plant were collected from 10 randomly collected plants in each of 8 harvests.
