Abstract/ Executive Summary:

To assess and compare the effect of different dhaincha accessions on soil health and grain yield of rice, nine dhaincha accessions were used as experimental materials along with a control (without dhaincha plant). The experiment was laid out in a randomized complete block design with three replications. Seeds of dhaincha accessions were sown in experimental plot @ 60 kg/ha. The 45 days old dhaincha plants were mixed up with soil. Soil samples were collected before sowing and after decomposition of dhaincha biomass and analyzed following standard procedure. There is a substantial increase in soil organic matter (up to 26%) and total nitrogen content (up to 25%) in soil after dhaincha incorporation. Thirty five days old, healthy rice seedlings were transplanted in the dhaincha incorporated plots at the spacing of 15 cm X 25 cm (plant-plant X row-row). The standard rice cultivation procedure was followed. Due to the incorporation of dhaincha biomass in soil, the grain yield was increased (up to 39%) compared to the control. Among the dhaincha accessions, number 95 showed the best performance in terms of grain yield. However, it is too early to make a conclusive remark based on only these very few number of dhaincha accessions. Therefore, a detailed study with a large number of germplasm collected from whole Bangladesh is obviously needed to reach in a precise conclusion.

Start Date: 00-04-2015

End Date: 00-12-2015

Program Area: Crop-Soil-Water Management

Commodity: Dhaincha, Soil Health

Objectives:

To find out the effect of different dhaincha accessions on soil health and grain yield of subsequent rice crop, with a long-term objective to recommend suitable cultivar (s) for different purpose(s) e.g.green manure, animal feed, fire-wood, pulp production etc.

Methodology:

The experiment was carried out at the Field Laboratory, Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, during April to December 2015. Nine dhaincha accessions collected (and preselected based on their biomass yield) from different locations of Bangladesh were used as experimental materials along with the control. The experiment was laid out in randomized complete block design with three replications. The treatment combinations were incorporation of different dhaincha accessions and a control (without incorporation of dhaincha). The unit plot size was 2.5 m x 2 m. Dhaincha crop was cultivated in the (Boro) rice–Fallow (dhaincha)–(T. Aman) rice, one of the most common cropping patterns in Bangladesh. Dhaincha seeds (@ 60 kg/ha and germination percentage >80%) were sown last week of April. The 45 days old dhaincha plants were incorporated into soil as green manure before transplanting of Aman rice (cv. BRRI dhan49). Soil samples were collected before sowing (initial) and after decomposition of dhaincha biomass and analyzed for organic matter (%) and total nitrogen content (%) in the Humboldt Soil Testing Laboratory, Department of Soil Science, Bangladesh Agricultural University, Mymensingh, following standard analytical procedures. For rice cultivation, the recommended dose (Urea-Triple Super Phosphate-Muriate of Potash-Gypsum @ 20-7-11-8 kg/Bigha, respectively) of TSP, MoP and gypsum fertilizers was applied during final land preparation (BRRI,2015). No N-fertilizer was used in Dhaincha incorporated plots. Healthy rice seedling of 35 days old were transplanted in the Dhaincha incorporated soil at the spacing at plant-plant X row-row of 15 cm x 25 cm, respectively. The standard rice cultivation procedure was followed (BRRI, 2015). Data on rice yield and yield components were recorded. Harvest index (%) was calculated using the formula, Harvest Index (%) = (Economic yield/Biological yield) x 100. Data were analyzed statistically following the analysis of variance (ANOVA) technique using MSTAT-C computer package (Russell, 1991) and means were separated by Duncan’s new multiple range test (DMRT) at 5% level of significance.

Achievement/Findings:

Dhaincha biomass incorporation through the appropriate cropping pattern, (Boro) rice/Winter vegetables-dhaincha-(T. Aman) rice, has potential effect on soil fertility and nutrient availability as well as the increment of crop production. Among the accessions studied, Acc. No. 95 incorporation produced the highest grain yield (4 t/ha) without applying any additional nitrogenous fertilizer. However, it is too early to make a conclusive remark with only these very few number of dhaincha accessions. Therefore, a detailed study with a large number of germplasm collected from whole Bangladesh is obviously needed to reach in a precise conclusion.
