Response of Mustard to Soil Test Based Fertilizer Management

Abstract

A field experiment was carried out at Sonapur of Muradnagar upazilla in Cumilla district under the Debidwar MLT (Multi-Location Testing) site during the rabi season of 2013-15. The experiment was conducted in the Old Meghna Estuarine Floodplain (AEZ-19) soil. The experiment was laid out in randomized complete block design (RCBD) with 3 replications.The treatments were: T1= Soil Test Based (STB) Fertilizer dose (FRG 2012), T2= T1+ 15% STB, T3= T1+ 30% STB, T4= 80% STB from inorganic fertilizer + 20% STB from CD/PM, T5= Farmers’ Practice andT6= Control. Among the treatments, T4 gave the maximum seed yield (1385.56 kg ha-1) which was at par with T1, T3 and T2 treatments. The lowest seed yield (450.20 kg ha-1) was obtained from T6 (Control).

Comparative Performance of Different Fertilizer Recommendation Methods on Growth and Yield of Rice (Oryza sativa) in Old Brahmaputra Floodplain Soils

“…Mamun et al [10] reported that using Soil Test Basis (STB) fertilizer recommendation method give more effective tillers hill -1 . Akhter [11] carried out a series of experiment about the effect of different fertilizer recommendation methods on rice and confirmed that fertilizer recommended through BAU soil testing kit gave highest panicle length, filled grains panicle -1 , 1000-grain weight, and yield. In rice grain, the highest N content (1.288%) was observed with BAU Soil Testing Kit (T4), while all treatments showed significantly higher nitrogen content compared to the control (Table 6).…”

“…The highest total nitrogen uptake by rice has also found in treatment T4 (108.84 kg ha -1 ). Akhter [11] reported that the plots treated by fertilizer recommended through BAU soil testing kit show higher content and N uptake in rice. The higher N uptake might be attributed to higher N application in BAU soil testing kit based fertlizer recommendation method.…”

“…All the treatments with fertilizer recommendations gave significantly higher value over the control (T1). Akhter [11] confirmed that the plots treated by fertilizer recommended through BAU soil testing kit resulted in significantly highest K uptake [12].…”
