Abstract/ Executive Summary:

A field experiment was conducted to study the effect of applied potassium fertilizer on growth and yield of two varieties of summer onion at the Horticulture Farm, Bangladesh Agricultural University, Mymensingh during March to June, 2005. In addition to potash, Cowdung, TSP, Gypsum and Zinc oxide were applied @ 5000, 150, 110 and 3 kg/ha as basal dose during final land preparation and mixed with soil properly. Urea was applied as the source of nitrogen. The urea and potash were applied treatment wise as side dressing with three installments at 15 days interval from one week after transplanting. Side dressing was followed by light irrigation with the help of watering cane. Potash was applied @ 0, 50, 75 and 100 kg K/ha. The positive effect of applied K was noted on both the varieties of onion. Maximum yield of 9.05 t/ha was obtained when K was applied to N 53 variety. The lowest yield of 6.33 t/ha was observed in no K fertilizer treatment in BARRI Piaz 2. It was observed that the application of K @ 75 kg/ha significantly increased the yield of both the varieties of onion. Key words: Summer onion, Potassium fertilizer, varieties, yield

Start Date: 00-03-2005

End Date: 00-06-2005

Program Area: Crop-Soil-Water Management

Commodity: Onion

Objectives:

1. To assess the impact of potash fertilizer on yield of two varieties of summer onion.

Methodology:

The study was conducted at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh following randomized complete block design with three replications. The factors taken for the experiment were: (i) two varieties of summer onion, viz., N 53 and BARI Piaz 2 and (ii) four levels of potassium, viz., 0, 50, 75 and 100 kg K/ha. Seeds were planted on the 9 of March 2005 and the seedlings were placed in lines 10 cm apart and were slightly covered with soil and irrigated with the help of sprinkler. Size of the unit plot was 1m × 1m. Cow dung, TSP, gypsum and Zinc Oxide were applied @ 5000, 150, 110 and 3 kg/ha as basal dose during final land preparation and mixed with soil properly. Urea was applied as the source of nitrogen. The urea and potash were applied treatment wise as side dressing with three installments at 15 days interval from one week after transplanting. Side dressing was followed by light irrigation with the help of watering cane. Potash was applied @ 0, 50, 75 and 100 kg K/ha. All other agronomic practices were kept uniform for both the varieties. The data recorded for yield were statistically analyzed on randomized completely block design for analysis of variance, while the treatment effects were compared by LSD Test.

Achievement/Findings:

It was clear that the combined effects of variety and potassium were found significant on the mean bulb yield. The highest yield (9.05 g) was found in cv. N 53 with 75 kg K/ha whereas the lowest bulb yields (6.33 g) was found in cv. BARI Piaz 2 with control dose of potassium
