Abstract/ Executive Summary:

A field experiment was carried out at the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, during rabi (winter) season of 2016-17 to evaluate the effects of fertilizer treatments on black cumin (BARI Kalozira-1). The field belongs to Shallow red-brown terrace soil of Salna series under AEZ-28 (Madhupur Tract). The experiment was laid out in randomized complete block design (RCBD) with three replications. Results showed that the application of nutrient elements had positive effect on plant height, branches per plant, capsule setting, umbels per plant, capsules per plant, capsule size, seeds per capsule, 1000-seed weight and seed yield of black cumin. The highest seed yield (1277 kg ha^-1) was obtained from 75% RDCF + 25% cowdung-N treatment followed by 100% RDCF (N80P45K50S20Zn5B2 kg ha^-1) and the lowest seed yield (420 kg ha^-1) was recorded with 50% RDCF. Thus,
the IPNS treatment 75% RDCF + 25% cowdung-N appeared to be the best suitable package for black cumin cultivation in this location.

Start Date: 00-00-2016

End Date: 00-00-2017

Program Area: Crop-Soil-Water Management

Commodity: Cumin

Objectives:

The present study was therefore, done to see the response of black cumin to chemical fertilizers and cowdung application in AEZ-28 (Madhupur Tract) soil.

Methodology:

The field experiment was conducted at the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur. The experimental field represents on Shallow red-brown terrace soil of Salna series (Plinthic Paleustult) under AEZ-28 (Madhupur Tract). The experiment was set up during rabi (winter) season of 2016-17. The geographic coordinates of the experimental location is 24009/ North Latitude and 90026/ East Longitude with an elevation of 8.2 m from mean sea level.

The experiment was set up in a randomized complete block design (RCBD) with seven treatment combinations having three replications. The treatments were T1= 100% RDCF (N80P45K50S20Zn5B2 kg ha-1), T2 = 75% RDCF + 25% N from cowdung, T3 = 50% RDCF + 50% N from Cowdung, T4 = 150% RDCF, T5 = 125% RDCF, T6 = 75% RDCF and T7 = 50% RDCF; RDCF means recommended dose of chemical fertilizers. The whole amount of cowdung, TSP, MoP, gypsum, zinc oxide and boric acid was applied as basal and 1/3rd urea was applied in three equal at 5th, 9th and 11th week after sowing. The seeds of black cumin cv. BARI Kalozira-1 were sown on 22 November 2016 in 2.5 m x 2.0 m plot at line to line distance 20 cm. Seeds were soaked in water for 24 hours to facilitate germination, then the seeds dried and treated with Bavistin (carbendazim) @ 2g kg^-1 seeds to minimize the primary seed-borne disease. The seeds were mixed with some loose soil to allow uniform sowing in rows @ 10 kg ha-1 at a depth of about one cm. The seeds were covered with loose soil properly just after sowing and gently pressed by hands with slight watering to enhance proper germination. Continuous sowing was done to maintain plant to plant distance of 10 cm by thinning after 25 DAS. Intercultural operations (four irrigations, three weeding and three times’ spray of Bavistin @ 2g L^-1 of water spray for controlling damping off disease) were done in the whole cropping period. Observations were done on the growth parameters like plant height and number of branches at 100 DAS. The crops were harvested on 20 March 2017, when as around 50 - 60% of the capsules turned into straw color from green. Ten plants were selected randomly from each plot for counting some growth and yield parameters. The harvested plants were sun dried for four days and threshing was done by beating with sticks. The seeds were winnowed and cleaned for recording data. The seed yield per plot was recorded from 1m² area and then converted to yield per hectare. The data were subjected to statistical analysis by using MSTAT software to find out the significance of variation between treatments. The difference between treatment means were judged by Duncan’s Multiple Range Test (DMRT) according to Gomez and Gomez (1984).

Achievement/Findings:

Fertilizer application played an important role on the growth and seed yield of black cumin. The fertilizer treatment T2 (75% RDCF + 25% N from cowdung) was observed as the best nutrient package for black cumin cultivation in Shallow Red-Brown Terrace Soil of Salna series under AEZ-28 (Madhupur Tract)
