Impact of Organic and Inorganic Fertilizers on Yield and Yield Contributing Characters of Mustard (Brassica napus L.)

Abstract

Bangladesh is a densely populated country where the oil crisis is one of the major issues. On the other hand, the balanced fertilizer used is lacking until now. The purpose of the study is to investigate the yield of Mustard (Brassica napus L.) Binasarisha-9 is influenced by the different applications of organic fertilizers. The experiment was conducted at Bangladesh Institute of Nuclear Agriculture (BINA), substation, Satkhira during the rabi season of 2020-2021 to observe the effect of organic and inorganic fertilizers on the yield of mustard (Brassica napus L.) viz Binasarisha-9 and determine the best dose of combined application of organic and inorganic fertilizers for optimum yield of mustard (Brassica napus L.) viz Binasarisha-9. The experiment was laid out in a randomized complete block design (RCBD) comprising five treatments (T1= Absolute control, T2=recommended dose chemical fertilizer (RDCF), T3=50% RDCF+ 5t/ha vermicompost, T4= 50% RDCF+ 5t/ha poultry manure, T5= 50% RDCF+ 5 ton/ha cow dung) with three replications were executed to conduct the study. Mustard (Brassica napus L.) was responded significantly to T3 treatment (50% RDCF+ 5t/ha vermicompost). The highest mustard yield was recorded (2.14 tons/ha) from T3 treatment whereas the lowest mustard (Brassica napus L.) yield (0.81 ton/ha) was obtained from T1= (absolute control) treatment. Balanced nutrient management application significantly increased mustard yield compared to the imbalanced treatment. Organic fertilizers (vermicompost, poultry manure, cow-dung) showed better nutrient uptake compared to chemical fertilizers. However, vermicompost tends to be the most suitable organic source for higher yield and thus is the proper substitute of the most commonly used nutrient sources for the production of mustard.

Enhancing Growth, Yield, and Physio-Chemical Properties of Mustard (Brassica Napus L) Through Combined Application of Organic and Inorganic Fertilizers Under Salinity Condition in Satkhira, Bangladesh

“…A similar result was also observed by Reza et al, (2022) andTripathi et al, (2010) who narrated that application of 50% RDCF along with vermicompost produced the highest yield and yield attributes of mustard. Furthermore, the combined application of 75% RDCF with 3 t ha -1 vermicompost also may reduce the risk of salinity stress on mustard yield.…”

“…These findings also revealed that the application of chemical fertilizers along with vermicomposting may mitigate the salinity effects on the mustard plant. A similar result was also observed by Reza et al, (2022) where the application of vermicompost along with chemical fertilizer improved mustard plant growth. In a column figures having similar letter (s) do not differ significantly whereas figures with dissimilar letter (s) differ significantly as per LSD at 5% level of probability.…”

Cropping system-based fertilizer strategies for crop productivity and soil health under minimum tillage in grey terrace soil

“…Additionally, due to the crops' extraction of nutrients from the soil's reserves, a deficiency in nutrients ensued. Reza et al [ 46 ], who utilized both wholly inorganic fertilizer and a blend of organic and inorganic fertilizer, likewise achieved identical outcomes.…”
