Abstract/ Executive Summary:

An experiment was carried out at the On Station research field of Agricultural Research Station, On-farm Research Division, Rangpur during 2014-15 and 2015-16 to investigate the effect of integrated nutrient management on the yield and quality of sweet pepper. There were six treatments: T1= 100% RD (N115P70K125S20Zn2 kg ha^-1), T2= 75% RD + 5 tha^-1 CD, T3= 75% RD + 5 tha^-1CD Slurry, T4= 75% RD + 3 tha^-1PM, T5= 75% RD + 3 tha^-1PM Slurry, T6= Native fertility. The tested variety was BARI Misti Morich-1. The experiment was laid out in randomize complete block design with 3 replications. Results revealed that the T5 (75% RD+ 3 tha^-1 PM Slurry) produced the highest fruit yield (25.29 & 25.79 tha^-1) and the lowest yield (16.34 & 11.27 tha^-1) was in control treatment (native fertility). An inclusion of 3 t PM Slurry ha^-1with 75% RD can reduce 25% of chemical fertilizer. Integrated use of PM Slurry at the rate of3 tha-1 with 75% RD was found as the best combinations in respect of sweet pepper yield and probable of enriching the soil organic matter.

Keywords: Sweet pepper, Nutrient management, Yield, Quality

Location: Research field of Agricultural Research Station, On-farm Research Division, Rangpur during the rabi seasons of 2014-15 and 2015-16.

Start Date: 00-00-2014

End Date: 00-00-2016

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer and manures, Sweet potato

Objectives:

The experiment was undertaken to study the effect of organic fertilizers on the yield of sweet pepper and to reduce the use of chemical fertilizer.

Methodology:

The study was conducted at the research field of Agricultural Research Station, On-farm Research Division, Rangpur during the rabi seasons of 2014-15 and 2015-16. The tested variety was BARI Misti Morich-1. Thirty five days seedlings was transplanted during second week of December. Crop harvesting was done three times started at last week of April and ended in second week of June. The initial soil samples of the experimental field were collected and analyzed following standard methods. Experimental layout and Data collection:The experiment was laid out in RCB design with three replications. The unit plot size was 3m ×1m with spacing of 50cm × 50cm. Thirty five days old sweet pepper seedlings were transplanted on 13 December, 2015. All the intercultural operations were done as and when necessary. The crop was harvested four times after the fruit maturity. The field data on important parameters were recorded from 5 randomly selected plants for analysis. The data on plant characteristics were collected on plant height, Number of fruitsplant-1, fruit length, fruit diameter, pericarp thickness, individual fruit fresh wt (gm), dry weight (gm) shelf life and yield (tha^-1). Data on different yield contributing parameters and yield were recorded and analyzed statistically and adjusted with least significant difference (LSD) at 5% level of significance.

Achievement/Findings:

Based upon the observation, it may be concluded that 3 t ha^-1 PM slurry along with 75% recommended dose of chemical fertilizer was found best for yield and quality of sweet pepper (cv. BARI Misti Morich-1. Among the 4 organic manures, poultry manure slurry was found best for sweet pepper production followed by poultry manure, cowdung slurry and cowdung.
