Abstract/ Executive Summary:

A pot experiment was carried out at the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh to assess the effects of salinity on some morpho-physiological and yield attributes of lentil genotypes, namely LM-30-3, E₅M-1018 and BARImasur-4 during November 2004 to March 2005. There were three salinity levels viz., control, 4 and 6 dS/m. The results showed that plant height, number of leaves, leaf area, number of pods number of seeds per plant, 1000-seed weight, seed yield per plant, total dry matter per plant and harvest index gradually decreased with the increase in salinity levels. Number of branches per plant decreased only at 6 dS/m. Genotypic response was not significant on those parameters.

Keywords: Salinity, Lentil and Yield

Location: Bangladesh Institute of Nuclear Agriculture, Mymensingh

Start Date: 08-11-2004

End Date: 30-03-2005

Program Area: Risk Management in Agriculture

Commodity: Lentil

Objectives:

The objective of the study was to observe the effect of salinity on morphological attributes and yield of lentil genotypes.

Methodology:

A pot experiment was conducted with three lentil genotypes viz., LM-30-3, EsM-1018 and BARImasur-4 in plastic pots at the Bangladesh Institute of Nuclear Agriculture, Mymensingh. There were three salinity levels viz., control (where only water was applied), 4 and 6 dS/m. Soil of the experimental pot was collected from the BINA farm. Each pot contained 8 kg of soil. Dry soil was thoroughly mixed with cowdung and fertilizers before pot filling. The experiment was laid out in randomized complete block design with three replications. Cowdung urea, TSP, MP, gypsum and borax were applied at final pot preparation at the rate of 70, 0.256, 0.616 and 0.256 g in each pot to maintain the doses of 12000, 32, 77 and 32 kg/ha of cowdung, urea, TSP and MP, respectively Lentil seeds were sown in pots on 8 November 2004. Several seeds were sown in each pot. Finally three plants were kept per pot. Salinity treatments were imposed at 35 days after sowing (DAS) by adding different amounts of salts ((NaCI 50%, NaS0₄ l5%, NaHC0₃ l0%, CaCl₂ l0%, MgCl₂ l0%, MgS0₄ 5%) (Burman et al., 2002) in the soils. Salinity (EC) of the pot soils was measured with Salinity Bridge. Data on morpho-physiological and yield attributes were recorded at 60 DAS and maturity. Data were analyzed B^yzed statistically to find out the levels of significance using the MSTAT-C package program. Duncan's Multiple Range Test (DMRT) was used to compare the differences of means.

Achievement/Findings:

Plant height, number of leaves, leaf area, number of pods number of seeds per plant, 1000-seed weight, seed yield per plant, total dry matter per plant and harvest index gradually decreased with the increase in salinity levels. Number of branches per plant decreased only at 6 dS/m. Genotypic response was not significant on those parameters.
