Abstract/ Executive Summary:

A field experiment was conducted at the research field of Agronomy Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during rabi season of 2014-15 to find out suitable intercrop combination of coriander with chickpea for pod borer insect suppression and economic benefit. There were six treatments in the experiment viz. T₁ =Sole Chickpea (40 cm line spacing), T2 =Sole coriander (broadcast), T3 =100% Chickpea + 25% coriander (One row coriander between two row chickpea), T4 =100% Chickpea + 50% coriander (Two row coriander between two row chickpea), T₅ =100% Chickpea + 75% coriander (Three row 5 coriander between two row chickpea), T6=100% chickpea + 100% coriander (Broadcast). Maximum pod borer infestation was observed in sole chickpea(13.71%) and infestation was reduced with the increase of coriander population intercrop situation. The minimum (3.65%) pod borer infestation was recorded in T₄ treatment. Chickpea yield and yield components were inversely related to pod borer infestation. The highest chickpea yield (1.40 t ha^-1 ) was obtained from treatment T₄ while the lowest (1.03 t ha^-1) from T₁ treatment. The highest chickpea equivalent yield (1.79 t ha^-1), gross return (Tk. 1, 25,020 ha^-1), gross margin (Tk. 36,000 ha^-1) and benefit cost ratio BCR (1.41) were obtained from treatment T₄ while the lowest from T₁ treatment.

Commodity: Coriander, Chickpea

Objectives:

To find out suitable intercrop combination of coriander with chickpea for pod borer insect suppression and economic benefit.

Methodology:

A field experiment was conducted at the research field of Agronomy Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during rabi season of 2014-15 to find out suitable intercrop combination of coriander with chickpea for pod borer insect suppression and economic benefit. There were six treatments in the experiment viz. T₁ =Sole Chickpea (40 cm line spacing), T2 =Sole coriander (broadcast), T3 =100% Chickpea + 25% coriander (One row coriander between two row chickpea), T4 =100% Chickpea + 50% coriander (Two row coriander between two row chickpea), T₅ =100% Chickpea + 75% coriander (Three row 5 coriander between two row chickpea), T6=100% chickpea + 100% coriander (Broadcast). The experiment was laid out in Randomized Complete Block Design with three replications. The unit plot size was 4.5 m x 3 m. Seeds of BARI Chola-7 and BARI Dhonia-1 were sown on 12 November, 2014. Fertilizers @ 160-48-120 kg ha NPK were applied at the time of final land preparation in the form of Urea, TSP and MoP, respectively. Except N and K, full amount of other fertilizer was applied at the time of final land preparation but N and K was applied in 2 equal splits at 21 and 45 DAS followed by irrigation. Intercultural operations were done as and when required. Coriander was harvested on 23 March, 2015 and chickpea was harvested 06 April, 2015. Yield component data of coriander and chickpea were collected from 10 randomly selected plants prior to harvest from each plot. At harvest, the yield data was recorded plot wise. Collected data were analyzed statistically and means were adjudged by LSD Test at 5% level of significance using MSTAT-C package. Yield of individual crop was converted into Chickpea equivalent yield (CEY) considering prevailing market price of the crops. Benefit cost analysis were also done. Chickpea equivalent yield (CEY) was calculated by The infestation of pod borer was highest (13.71 %) in the formulae.
