EFFECT OF SULPHUR AND LIQUID FERTILIZER ON YIELD AND YIELD COMPONENTS OF MUSTARD VAR. BINASARISHA-4

Abstract

An experiment was carried out to investigate the effect of sulphur and foliar application of liquid fertilizer ‘Magic growth’ on the yield and yield components of mustard var. Binasarisha-4 at a farmer’s field of South Surma Upazila of Sylhet district from October, 2012 to February, 2013. There were five treatments- T0 = No sulphur (control), T1 = 10 kg S ha -1 + liquid fertilizer as super imposed and T4 = No fertilizer except foliar application of liquid fertilizer. The source of sulphur was gypsum and recommended dose of NPKZnB were applied in all plots except T4. The unit plot size was 4 m x 2.5 m, laid out in a randomized complete block design with three replications. Data on yield and yield contributing characters were recorded at harvest and statistically analyzed. Results of the experiment showed that levels of S fertilization significantly influenced some plant and yield parameters and increased the number of siliqua plant , T2 = 20 kg S ha -1 , T3 = 40 kg S ha -1 and also 1000 seed weight. However, S @ 20 kg ha -1 , seeds siliqua -1 (T2) in maximum cases showed the best performances which resulted in the highest yield (1883 kg ha -1 ). The highest straw yield and total dry matter production were both obtained from 40 kg S ha -1 + liquid fertilizer. Although straw yield and total dry matter production progressively increased with higher levels of S up to 40 kg ha -1 -1 . The lowest plant parameters, least seed and straw yields and the lowest total dry matter were found in the treatment no fertilizer + foliar application of liquid fertilizer.

but seed yield increased up to S rate of 20 kg ha -1
