Abstract/ Executive Summary:

Keywords: Sweet gourd, Pumpkin, Fertilizer

Location: Horticulture Research Centre, BARI, Joydebpur, Gazipur Bangladesh

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer, Sweet gourd

Objectives:

1. To develop a fertilizer recommendation both with prilled urea and USG for pumpkin and

2. To evaluate the performance of USG to prilled urea in pumpkin production.

Methodology:

The experiment was conducted in the field of HRC, BARI during winter 2016-17 followed by RCBD with three replication. Seven treatments were considered as- T₁= N₈₀P₃₅K₇₅S₂₀ +Zn₄B_1.5 (N as prilled urea); T₂= N₈₀P₃₅K₇₅S₂₀ +Zn₄B_1.5 (N as USG); T₃= 20% higher NPKS than T₁ + Zn₄B_1.5(N as prilled urea); T₄= 20% higher NPKS than T₁ + Zn₄B_1.5(N as USG); T₅= 20% lower NPKS than T₁ + Zn₄B_1.5(N as prilled urea); T₆= 20% lower NPKS than T₁ + Zn₄B_1.5(N as USG) and T₇= Native fertility. The land was fertilized with well decomposed cowdung @ 5 t/ha cowdung, Entire cowdung, P, K, S, Zn and B were applied during pit preparation which was 7 days before transplanting. Prilled urea was top dressed in 3 split as 25% at 10 DAT, 50% at 35-40 DAT and 25 % at 70-75 DAT mixing with soil. But USG was applied in two equal splits at 10 DAT followed by ring 10 cm apart from plant base and 7-8 cm deep placement method and at 60 DAT followed by dibbling method maintaining the same depth. Crop variety BARI Hybrid pumpkin-1 was used as a test crop. Crop was transplanted in November 30, 2016 with 25 day old seedling for both the years. The soil sample of the experimental plot was collected and analyzed and the results were presented in the following table A. Necessary data were recorded and was analyzed with help of computer package MSTATC and means were separated followed by DMRT with 5% level of significance.

Achievement/Findings:

From above discussion it was clearly observed that performance of USG is better than the prilled urea but 20% higher dose of USG produces higher vegetative growth and consequently reduced total yield of sweet gourd. In case of prilled urea 20% higher dose of prilled urea performed better than the recommended prilled urea. But in case of USG, recommended dose of USG followed by 20 % less than recommended dose of USG performed better in sweet gourd production in 2016-17 and it was better in 20 % lower dose of USG in 2017-18. The experiment will be continued for the next year for further confirmation.
