Abstract/ Executive Summary:

An experiment was conducted at farmer’s field of Kushtia sadar MLT site under AEZ 11 during three consecutive years at 2001-2004 to find out the rate of nutrients (NPKS) for Onion (Taherpuri), T. aus (IR-50) and T. aman rice (BR-11) to NPKS on the yield under AEZ11. Four different levels of NPKS were assigned in RCB design with 4 replications. Average of three years study reveals that a considerable response of Onion, T. aus and T. aman rice to NPKS was observed. However, the response to P, K and S was more distinct in comparison to N. Similarly, the response was more evident in Onion compared with T. aus and T. aman rice. Yield of Onion increased up to the application of 120, 43, 120 and 20 kg/ha of N, P, K and S, respectively. Yield of T. aus and T. aman rice increased up to the application of 70, 18, 34 and 10 kg/ha of N, P, K and S, respectively. From the regression analysis it was found that the relationship was almost quadratic in nature. The application of 115-40-118-18 kg NPKS/ha for Onion, 63- 19-29-9 kg NPKS/ha for T. aus rice and 65-17-33-9 kg NPKS/ha for T. aman rice was the most economically optimum fertilizer dose in the High Ganges River Floodplain Soil under AEZ 11.

Keywords: Onion, T. aus, T. aman, NPKS fertilizer

Location: Farmer’s field of Multilocation testing (MLT) site Kushtia sadar, Kushtia district

Start Date: 00-00-2001

End Date: 00-00-2004

Program Area: Farming System

Commodity: Fertilizer, Onion, Rice

Objectives:

To determine an economically optimal dose of fertilizer nutrients for Onion - T. aus - T. aman rice cropping pattern at Kustia under AEZ11.

Methodology:

The experiment was conducted at farmer’s field of Multilocation testing (MLT) site Kushtia sadar under Kushtia district (AEZ-ll and land type-MHL) during 2001-2004 with Onion - T. aus - T. aman cropping system. The soil was silt loom having pH 8.1, initial Soil organic matter 1.88%. total N 0.15%, exchangeable K 0.69 meq/l00g soil, Olsen's P 3.98 ppm, available S 30 ppm, available Zn 0.82 ppm and available B 0.36 ppm. The experimental plot of onion was laid out in randomized complete block design with four dispersed replications. The unit plot size was 5m x 3m. Four different levels of N (0, 60, 120 and 180), P (0, 22, 43 and 65), K (0, 60, 120 and 180) and S (0, 10, 20 and 30) for Onion, T. aus and T. aman rice was tested based on the soil analysis. Onion (var. Taherpuri) seed was sown on 02 November and harvested on 6 April. Forty days old seedlings of T. aus (var. IR-20) rice were transplanted on 25 May with a spacing of 25 cm × 15 cm and harvested on 05 August. Forty days old seedlings of T. aman rice (var. BR-22) were transplanted on 18 August with a spacing of 20 cm × 15 cm and were harvested on 12 December. Fertilizer doses were calculated according to original soil status of the experimental plots using Fertilizer Recommendation Guide 1997. In case of Onion, half of N and the whole amount of P, K, S, Zn were applied at the time of final land preparation. The rest half of N was top-dressed at 40 days after sowing. In case of rice the entire quantity of P, K, S and Zn were applied as basal dose at the time of final land preparation and N was applied in three equal splits as top dress at 15 DAT, at maximum tillering stage and before panicle initiation stage. Data on yield and yield attributes were recorded and analyzed statistically by Duncans Multiple Range Test (DMRT). Regression analysis was done and the optimum and economic dose of fertilizer nutrients were calculated using the formula Y = - b/2c and Y= 1/2c (Pf/Py-b), respectively from the response curve.

Achievement/Findings:

Fertilizer dose that maximized yield of Onion was 120-43-120-20 kg NPKS/ha, T. aus rice was 70-18-34-10 kg NPKS/ha and 70-18-34-10 kg NPKS/ha for T. aman rice while 115-40-118-18 kg NPKS/ha was profitable for Onion, 63- 19-29-9 kg NPKS/ha for T. aus and 65-17-33-9 kg NPKS/ha for T. aman in respect of yield and economics. The present recommended dose is relatively lower but judicious that ensures higher yield than that of farmer’s traditional practices; and it will be helpful to improve soil health for sustainable higher yield. So, 115-40-118-18 kg NPKS/ha for Onion, 63-19-29-9 kg NPKS/ha for T. aus and 65-17-33-9 kg NPKS/ha for T. aman rice could be proposed for recommendation in high Ganges river floodplain area under AEZ 11.
