Effect of Fertilizer Management on Chilli+sweet Gourd Intercropping System

Chief Scientific Officer & Head, OFRD and Relevant Scientists of OFRD, BARI

Abstract/ Executive Summary:

An intercropping experiment was conducted in the farmer’s field at Multi-Location Testing site, Malancha, Melandah, Jamalpur during Rabi season of 2014-15 to determine the productivity and economic performance of fertilizer management of chilli+sweet gourd intercropping systems. The treatments were: T₁= 100% sweet gourd (2m×2m)+40% chilli (50cm×100cm)+100% recommended fertilizer (RF) for chilli, T₂= 100% sweet gourd (2m×2m)+40% chilli (50cm×100cm)+75% RF for chilli, T₃= 100% sweet gourd (2m×2m)+50% chilli (50cm×80cm)+100% RF for chilli. Yield and yield attributes of sweet gourd was influenced significantly by fertilizer application in the intercropping systems. 25% reduction of fertilizer in chilli as in T₂ (100% sweet gourd+40% chilli +75% RF) significantly reduced yield of both sweet gourd and chilli but increasing population of chilli by 10% did not affect yield of sweet gourd but increased yield of chilli.The highest fruit yield (34.12 t ha^-1) of sweet gourd was found from T₃ and the lowest (27.98 t ha^-1) from T₂. The highest sweet gourd equivalent yield (96.12 t ha^_-1) was obtained from T₃ which gave 29.49% higher yield advantage over T₂. The gross return (Tk. 3,84,480 ha^-1) and gross margin (Tk. 2,93,565 ha^-1) were also found the highest from 100% sweet gourd +50% chilli +100% RF (T₃). Data on different parameters were recorded and analysed. Means were separated as per LSD test

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer

Objectives:

To ascertain the effect of fertilizer management on chilli+sweetgourd intercropping in farmer's field.

Methodology:

The experiment was conducted at Multi-Location Testing site, Malancha, Melandah, Jamalpur during Rabi season of 2014-15. The experiment consisted of three treatments, viz., T₁= 100% sweet gourd (2m×2m)+40% chilli (50cm×100cm)+100% recommended fertilizer (RF) for chilli, T₂= 100% sweet gourd (2m×2m)+40% chilli (50cm×100cm)+75% RF for chilli, and T₃= 100% sweet gourd (2m×2m) +50% chilli (50cm×80cm)+100% RF for chilli. The treatments were tested in randomized complete block design with 4 replications. The unit plot size was 3m × 4m. The variety BARI Mistikumra-2 and local variety were used for sweet gourd and chilli, respectively. Sweet gourd seedling was transplanted in 2m × 2m and chilli seeds were sown in broadcast maintaining the percentage of seeds. Chilli was fertilized with 120-80-120-20-4 kg ha^-1 NPKSZn and 5 t ha^-1 cowdung. Half N and full amount of other fertilizer were applied as basal. Rest of N was applied in three equal split as ring dressing 20, 50 and 70 days after transplanting. On the hand, before 10 days of sweet gourd transplanting 4 kg cowdung 50g TSP, 35g MOP was applied per pit as basal. At 10 DAT, 35g urea+30 g MoP, at 30 and 50 DAT 35g urea and at 70 DAT 20 g urea were applied as ring dressing followed by irrigation. The seeds of chilli were sown on 1 October and seedlings of sweet gourd were planted on 16 November, 2014. Three hand weeding was done at 30, 50 and 70 DAP. Chilli was harvested on 10-22 February 2015. Sweet gourd was harvested on 15 March to 15 April, 2015. Equivalent yield of component crops were determined following the method of Anjaneyulu et al. (1982). For example, Sweet gourd Equivalent Yield (SEY)= Ys+ {(Yi × Pi)/Ps}.

Achievement/Findings:

Based on cost and return analysis, agro-economically profitable fertilizer dose was found to be T₃ (100% Sweet gourd+50% chilli+100% recommended dose (@ 120-80-120-204 kg ha^-1 NPKSZn) for chilli+sweet gourd intercropping systems.
