Abstract/ Executive Summary:

The experiment was conducted at RARS, Jessore, during rabi of 2001-2002 to find out the suitable fertilizer dose in hybrid maize-mungbean- T. aman rice cropping pattern. Fertilizer dose for hybrid maize were as follows: F₁=350-180-180-45 kg/ha of n-P-K-S and F₂=300-150-150-38g/ha of N-P-K-S, F₃= 205-120-120-30 kg/ha of N-P_K-S and F₄=200-90-90-22 kg/ha of N-P-K-S Maize (cv. BARI hybrid maize-1) was sown on 18 November, 2001. Two weeding was done at 35 and 55 DAE. The crop was harvested on 17 April, 2002 at maturity. At Joydebpur the highest grain yield (6.27 t/ha) was obtained from T₂treatment, which was statistically identical with T₁ (6.17 t/ha) and T₃ (15 t/ha)treatment but significantly higher than T₄ treatment. Variation of fertilizer doses had no significant influence on the stover yield. The highest benefit cost ratio was obtained from T₄ treatment (1.71 tk/tk). At Jessore yield and yield attributes were significantly influence by the variation of fertilizer doses. The highest grain yield was obtained from T₁(8.64 t/ha) treatment, which was identical with T₂ (8.44 t/ha) treatment and lowest grain yield was obtained T₄(7.68 t/ha) treatment. Almost similar trend was found for stover yield. The highest benefit cost ratio was obtained from T₄ treatment (3.61 tk/tk).

Keywords: Hybrid maize, Mungbean, T. Aman, Fertilizer levels

Location: Joydebpur and RARS, Jessore

Start Date: 18-11-2001

End Date: 25-10-2002

Program Area: Crop-Soil-Water Management

Commodity: Maize, Rice, Mungbean

Objectives:

To find out the suitable fertilizer dose and to study the suitability of this Mungbean-maize-T. aman pattern.

Methodology:

An experiment on hybrid maize-mungbean-T. aman rice was conducted during rabi season on of 2001-2002 at the farm of Central Research Station, BARI, Joydebpur and RARS, Jessore. Hybrid maize (var. BARI-hybrid-1) was grown as first crop. The following fertilizer doses were tested on hybrid maize:T₁=350-180-180-45 kg/ha N-P₂O₅-K₂O-S, T₂= 300-150-150-38 kg/ha N-P₂O₅-K₂O-S, T₃=250-120-120-30 kg/ha N-P₂O₅-K₂O-S, T₄=200-80-90-22 kg/ha N-P₂O₅-K₂O-S. above treatments were replicated four times in RCBD. Zinc fertilizer (4kg/ha ) was used for all the treatments as blanket. The unit plot size was 5m x 4.5m). Data was collected for maize no of plants/m², plant height, cob height, length of cob, grains/cob,1000 grain weight and grain yield and for mungbean no of plants/m², plant height, no of pods/plant, no of seed/pod, 1000 seed weight and yield.

Budget: 10,000/-

Total Budget (Tk.) : 10,000/-

Achievement/Findings:

The highest yield was obtained from F₁ and F₂attributed the higher number of cobs/m2 and 1000-grain weight. Treatment F₄ indicated better BCR of 3.61 as compared to others.
