Abstract/ Executive Summary:

The experiment was conducted at the Regional Agricultural Research Station, BARI, Jessore during consecutive two years (2007-08 and 2008-09) to find out the comparative performance of different intercropped lentil with Mukhikachu for getting higher yield and economic return. Five treatments comprised of T₁= Sole lentil (30 cm apart continuous seeding), T₂ = Sole mukhikachu [(double row) = 20 cm/55/20 cm x 45 cm], T₃= Mukhikachu (double row) + 1 row of lentil 30 cm apart (33% seeding ratio) between 2 double row of mukhikachu, T₄ = Mukhikachu (double row) + 2 rows of lentil 30 cm apart (66%) between 2 double row of mukhikachu and T₅= Mukhikachu (double row) + lentil broadcast (100%). Intercropping systems did not affect the rhizome yield of mukhikachu significantly but affected the seed yield of lentil. Lentil and mukhikachu equivalent yield were the highest (5.87 in 2007-08 and 6.09 t/ha in 2008-09, and 27.24 in 2007-08 and 30.45 t/ha in 2008-09, respectively) in treatment T₄. This treatment also gave the highest LER (1.63 in 2007-08 and 1.54 in 2008-09), net return (Tk. 290508 in 2007-08 and Tk. 368900/ha in 2008-09) with BCR of 4.19 in 2007-08 and 4.88 in 2008-09, respectively. It reveals that lentil could be grown easily in double row system of Mukhikachu without hampering yield of Mukhikachu with higher benefit and also enhanced lentil production in the area.

Commodity: Lentil, Aroids

Objectives:

To find out the comparative performance of different intercropped lentil with Mukhikachu for getting higher yield and economic return.

Methodology:

The experiment was carried out under rainfed condition at the Regional Agricultural Research Station, BARI, Jessore during two consecutive years November 2007 to August 2008 and November 2008 to August 2009 to find out the comparative performance of different intercropped lentil with Mukhikachu. The soil type of the experimental plot was sandy loam under AEZ 11. The total rainfall during crop period was 1050.08 mm in 2007-08 and 844.90 mm in 2008-09, respectively. Five treatments were tested in randomized complete block design with three replications. Treatments comprised T₁= Sole lentil (30 cm apart continuous seeding), T₂ = Sole Mukhikachu [(double row) = 20 cm/55/20cm x 45 cm], T₃= Mukhikachu (double row) + 1 row of lentil 30 cm apart (33% seeding ratio) between 2 double row of Mukhikachu, T₄ = Mukhikachu (double row) + 2 rows of lentil 30 cm apart (66%) between 2 double row of Mukhikachu and T₅= Mukhikachu (double row) + lentil broadcast (100%). The Mukhikachu variety BARI Mukhikachu 1 (Bilasi) and lentil variety BARI Masur 5 were used as the test crops. Seed rate of lentil and Mukhikachu were used 35 and 600 kg/ha, respectively. The unit plot size was 3.0m x 4.5m. Sowing was done on 10 November 2007 and 15 November 2008, respectively. Fertilizers (BARC, 2005) were applied 15-18-15 N, P, and K kg/ha in the form of urea, triple super phosphate, and muriate of potash for lentil sole at the time of final land preparation. On the other hand, fertilizers (BARC, 2005) used for sole Mukhikachu and intercrop were 112-32-95-20 kg/ha NPKS, respectively. Except urea, all other fertilizers were applied during final land preparation. Urea was applied in two equal splits at 45 and 100 days after emergence of Mukhikachu in rows only. Plant protection measure and all other management practices were done as and when necessary. After harvest of lentil, supplementary irrigation was applied. Lentil was harvested on 12 and 15 March 2008 and 2009, whereas Mukhikachu on 10 and 16 August 2008 and 2009, respectively. Ten plants of lentil and Mukhikachu were selected randomly per plot to collect data on their yield attributes. Yield data was taken as whole plot basis which was expressed in t/ha, Yield of individual crop was converted into equivalent yield on the basis of the prevailing market price of respective crop (Bandyopadhyay, 1984). Relative yield was measured according to Jukinen (1991) and land equivalent ration (LER) was also calculated as per Mead and Willey (1980). Gross return, total cost of cultivation, net return and benefit cost ratio (BCR) of different treatments were computed on the basis of prevailing market price of lentil and Mukhikachu. All necessary data were collected and analyzed by using MSTAT-C program. Means were separated by LSD (p≤ 0.05) test.

Achievement/Findings:

Intercropping systems did not affect the rhizome yield of mukhikachu significantly but affected the seed yield of lentil. Lentil and mukhikachu equivalent yield were the highest (5.87 in 2007-08 and 6.09 t/ha in 2008-09, and 27.24 in 2007-08 and 30.45 t/ha in 2008-09, respectively) in treatment T₄. This treatment also gave the highest LER (1.63 in 2007-08 and 1.54 in 2008-09), net return (Tk. 290508 in 2007-08 and Tk. 368900/ha in 2008-09) with BCR of 4.19 in 2007-08 and 4.88 in 2008-09, respectively. It reveals that lentil could be grown easily in double row system of Mukhikachu without hampering yield of Mukhikachu with higher benefit and also enhanced lentil production in the area.
