Abstract/ Executive Summary:

The experiment was conducted at Regional Agricultural Research Station, Rahmatpur, Barisal during Rabi season of 2016-2017 and 2017-18 to find out the suitable combination of inorganic fertilizers and organic fertilizers with proper planting technique in a randomized complete block design. Nine treatments viz.T₁=100%of RF+Bio-slurry 0 tha^-1,T₂= 100% of RF+Bio-slurry 5 tha^-1,T₃=100% of RF+Bio-slurry 10 tha^-1,T₄=50% of RF+ Bio-slurry 0 tha^-1,T₅=50% of RF+Bio-slurry 5 tha^-1,T₆=50% of RF+Bio-slurry 10 tha^-1,T₇=75% of RF +Bio-slurry 0 tha^-1,T₈=75% of RF+Bio-slurry 5tha^-1,T₉=75% of RF + Bio-slurry 10 tha-1. The result revealed that when 100% recommended dose of fertilizers was used with 10 tha^-1 of bio-slurry gave the highest yield (3.96 and 3.86 tha^-1) which was statistically similar to the yield (3.91 and 3.84 tha^-1) in T₉ treatment where 10 tha^-1 of bio-slurry was applied with 75% of recommended fertilizers.

Commodity: Nutrient status, Wheat

Objectives:

To study the suitable combination of inorganic and organic fertilizers for higher yield and economic return.

Methodology:

Experimental site- A field experiment was conducted at the Regional Agricultural Research Station, Rahmatpur, Barisal during rabi 2016-2017 and 2017-18. The soil of the plot was sandy loam in texture having pH 7.5, total N, available P and K were 0.08%, 16.8 µg g^-1 soil, and 0.09 meq per 100 g of soil, respectively. Treatments and experimental design- BARI Gom 26 was used as the test crop. The experiment was comprised of nine treatments i.e. T₁=100% of RF + Bio-slurry 0 tha^-1, T₂= 100% of RF + Bio-slurry 5 tha^-1, T₃= 100% of RF + Bio-slurry 10 tha^-1, T₄= 50% of RF + Bio-slurry 0 tha^-1, T₅= 50% of RF + Bio-slurry 5 tha^-1, T₆= 50% of RF + Bio-slurry10 tha^-1, T₇= 75% of RF + Bio-slurry 0 tha^-1, T₈= 75% of RF + Bio-slurry 5 tha^-1, T₉= 75% of RF + Bio-slurry 10 tha^-1. The experiment was laid out in a randomized complete block design with 3 replications and spacing of 30 cm between rows and 20 cm between plants. Unit plot size was (4 X 3) m². Fertilizer and bio-slurry application- Fertilizer was applied according to treatment specifications. Nutrients were calculated on an IPNS basis and just the necessary amount of fertilizer was applied. Except for Urea, all other fertilizers and bio-slurry were applied in whole amounts during the final land preparation. Urea was applied at 25 DAS and 50 DAS as a split dose. Cultivation practices- The seeds were sown on 19 November 2016 and 21 November 2017. Irrigation was given at 35 DAS and 55 DAS for both seasons. Weeding was done as and when necessary. The crop was always kept under careful observation until it was harvested. Wheat seeds were cured for 6 days in the sun at 14% moisture before storing in an ordinary room. Ten plants were selected at random from each plot for the collection of data. Data collection- Data on the following parameters were recorded during the period of the experiment as Plant height (cm), No. of plants m^-2, Spikes m^-2, Length of a spike (cm), Grains spike^-1, 1000-seed weight (g), yield (tha^-1). Statistical analysis- The collected data were compiled and analyzed statistically using the analysis of variance (ANOVA) technique and the mean differences were adjudged by LSD test using the statistical computer package program, Statistics 10.

Achievement/Findings:

Bio-slurry is an important organic fertilizer that helps in quality crop production and enhances soil quality. As it is digested anaerobically, it supplies more nutrients than cowdung. Results from the study showed that bio-slurry along with chemical fertilizer increased the yield and quality of wheat. Yield is higher in T₃ treatment where 100% recommended fertilizers were applied with 10 tha^-1bio-slurry. So, farmers can use bio-slurry along with chemical fertilizers for improving yield and quality.
