Abstract/ Executive Summary:

Effects of different sources of organic materials on the nutrient contents and their uptake by T. aman rice were evaluated in a field experiment during July to October 2011 at Bangladesh Agricultural University farm, Mymensingh. Ten treatments formulated from organic manures and chemical fertilizers were T₀ : Control, T₁ : Recommended doses of N, P, K and S (RD-NPKS), T₂ : Green manure @ 10 t ha^-1 (GM10 t/ha ), T₃ : GM @ 5 t ha^-1 + Rice straw @ 5 t ha^-1 (GM 5t/ha + RS5 t/ha), T₄ : GM @ 5 t ha^-1 +Farm yard manure @ 5 t ha^-1(GM 5 t/ha + FYM 5 t/ha), T₅ : Oil cake @ 2.5 t ha^-1 (OC2.5 t/ha), T₆ : GM @ 5 t ha^-1 + FYM @ 5 t ha^-1+ Phosphate solubilizing bacteria (GM 5 t/ha + FYM 5 t/ha + PSB), T₇ : GM @ 5 t ha^-1 + PSB (GM 5 t/ha + PSB), T₈ : FYM @ 5 t ha^-1 + PSB (FYM 5 t/ha + PSB) and T₉ : RD-NPKS + PSB. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Among the organic materials used, farm yard manure was better than other organic sources due to its higher nutrient content except green manure which contained higher amount of N. The nutrient contents (N, P, K, S, Ca and Mg) and their uptake by grain and straw were significantly influenced by the application of different treatments except the S content of grain. The highest values of most of the parameters were obtained from RD-NPKS + PSB treatment which was statistically identical with GM 5 t/ha +FYM 5 t/ha + PSB, GM10 t/ha and GM 5 t/ha + FYM 5 t/ha treatment combinations in many cases. The lowest values for all the parameters were obtained from control. The overall findings of the study indicated that the use organic manure could be important for increasing nutrient contents and their uptake by T. aman rice.

Start Date: 11-07-2011

End Date: 27-12-2011

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

1. To investigate the effects of different sources of organic materials on the nutritional status of T. aman rice.

Methodology:

The field experiment was carried out during aman season from 11 July to 27 December, 2011 at the central farm of Bangladesh Agricultural University, Mymensingh. Initial soil sample was collected, processed and kept in a polyethylene bag for chemical analysis. The soil was silt loam textured having pH 6.49, organic carbon 0.72%, total N 0.12%, available P 12.1µg g^-1 soil, exchangeable K 0.5 c mol kg^-1 available S 9.28 µg g^-1 . Seeds were collected from Bangladesh Agricultural Development Corporation (BADC). There were 10 treatments combination viz. T0 : Control, T₁ : Recommended doses of N, P, K and S (RD-NPKS), T₂ : Green manure @ 10 t ha^-1 (GM10 t/ha ), T₃ : GM @ 5 t ha^-1 + Rice straw @ 5 t ha^-1 (GM 5t/ha + RS5 t/ha), T₄ : GM @ 5 t ha^-1 +Farm yard manure @ 5 t ha^-1 (GM 5 t/ha + FYM 5 t/ha), T₅ : Oil cake @ 2.5 t ha^-1 (OC2.5 t/ha), T₆ : GM @ 5 t ha^-1 + FYM @ 5 t ha^-1 + Phosphate solubilizing bacteria (GM 5 t/ha + FYM 5 t/ha + PSB), T₇ : GM @ 5 t ha^-1 + PSB (GM 5 t/ha + PSB), T₈ : FYM @ 5 t ha^-1 + PSB (FYM 5 t/ha + PSB) and T₉ : RD-NPKS + PSB. The experiment was laid out in randomized complete block design with three replications. The unit plot size was 4 m × 2.5 m. The total number of unit plots were 30. The spaces between the unit plots were 1m and 0.5 m, respectively. Half of N and full doses of P, K, S were applied at the time of puddling and remaining N was applied in early tillering, late tillering and panicle initiation stage. Rice straw was chopped and incorporated into soil 7 days before transplanting. Oil cake and farm yard manure were applied one day before transplanting of rice. Chemical composition of the organic manure used in the experiment from rice straw contained highest amount of organic carbon (41.14%) which was followed by OC (39.06%) and GM (36.75%) and the lowest C content was found in FYM (35.16%). In contrast, the highest N content (5%) was obtained from GM which was followed by OC (2.46%) and FYM (1.60%) and the lowest N content was from RS (0.65%). High P (1.80%) was contained in FYM followed by GM (.83%) and OC (0.40%). On the other hand, the highest amounts of K, S, Ca and Mg were found in FYM and the lowest amount of all these nutrients except K were obtained from RS. The test crop was T. aman rice var. BRRI dhan49. Seeds were sown on July 11, 2011 and transplanting was done August 7, 2011. Weeding, gap filling, thinning, irrigation and pesticide application were performed as and when necessary throughout the growing period. The plants were harvested on November 27, 2011. N, P, K, S, Ca and Mg contents were determined following standard methods. Nutrient uptake was calculated by multiplication of concentration (%) with dry matter yield and divided by 100. Analysis of variance was done with the help of computer package program MSTAT and the mean differences were adjudged by DMRT.

Achievement/Findings:

Among the organic materials used, farm yard manure was better than other organic sources due to its higher nutrient content except green manure which contained higher amount of N. The nutrient contents (N, P, K, S, Ca and Mg) and their uptake by grain and straw were significantly influenced by the application of different treatments except the S content of grain. The highest values of most of the parameters were obtained from RD-NPKS + PSB treatment which was statistically identical with GM 5 t/ha +FYM 5 t/ha + PSB, GM10 t/ha and GM 5 t/ha + FYM 5 t/ha treatment combinations in many cases. The lowest values for all the parameters were obtained from control. The overall findings of the study indicated that the use organic manure could be important for increasing nutrient contents and their uptake by T. aman rice.
