Integrated Nutrient Management for Chilli in the Southern Region of Bangladesh

Abstract

A field experiment was conducted at Regional Agricultural Research Station, Rahmatpur, Barishal during November 2016 to June 2017 to develop nutrient management practice for chilli in the southern region of Bangladesh. The crop variety was BARI Marich 2. Poultry manure was used with chemical fertilizers. There were five treatments viz. T1: Soil test base (STB) fertilizer dose for HYV, T2: STB + 5t/ha poultry manure, T3: 50% STB + 5t/ha poultry manure, T4: FRG’2012 for HYV (100-60-100-20-2-1 kg N-P-K-S-Zn-B ha-1) and T5: Absolute control which were replicated for four times. Poultry manure along with chemical fertilizers had significant influence on plant height (cm), root length, shoot and root dry weight, no of fruits plant-1, fruit yield plant-1, fruit yield plot-1 and fruit yield ha-1 (t) of chilli. Significantly the highest fruit yield (40.98 t ha-1) along with root (3.06 g) and shoot (13.54) dry weight, no of fruits plant-1 (27.10), yield plant-1 (23.52 g) was recorded with STB + 5t/ha poultry manure which was statistically similar with the results obtained from 50% STB + 5t/ha poultry manure. Therefore, 50% STB could be reduced when integrated use of poultry manure with chemical fertilizers in chilli cultivation in southern region, Barishal (Non–calcareous Grey Floodplain Soils under AEZ 13).
