Impact of different combined doses of fertilizers with plant growth regulators on growth, yield attributes and yield of mustard (Brassica campestris cv. B9) under old alluvial soil of Burdwan, West Bengal, India

Abstract

Impact of different combined doses of fertilizers with plant growth regulators on growth, yield attributes and yield of mustard (Brassica campestris cv. B 9 ) under old alluvial soil of Burdwan, West Bengal, IndiaAbstract Field experiments were conducted with mustard (Brassica campestris cv. B 9 ) consecutively for three years (2005, 2006 and 2007) in the Crop Research and Seed Multiplication Farm of Burdwan University, Burdwan, West Bengal, India. In the first year, varietal screening of mustard under recommended dose of chemical fertilizer (100∶50∶50) were performed with seven mustard varieties during November 2005 to February 2006. In the second year, two experiments were conducted to study the effects of six different combined doses of chemical fertilizer and biofertilizer and six different levels of growth retardant cycocel. In the third year, six different levels of compost along with the best screened dose of growth retardant (CCC-300 ppm) and the best combined dose of biofertilizer and chemical fertilizer (3/4thchemical fertilizer:1/4th biofertilizer) from the previous year were applied to study the effects on agronomic traits and growth attributes of mustard, and the field data were analyzed statistically. The variety B 9 recorded a significant higher seed yield along with other yield contributing factors, which was found to be superior to other varieties under old alluvial soil of Burdwan, West Bengal, India, in 2005, seed yield was found to be the best for CCC-300 ppm treatment and the best combined dose of biofertilizer and chemical fertilizer was found to be 3/4th chemical fertilizer:1/4th biofertilizer. In 2007, the best yield was given by the treatment of 7.5 t$hm -2 compost along with the best dose of growth retardant cycocel and the best combined dose of biofertilizer and chemical fertilizer.

Response of Mustard to Soil Test Based Fertilizer Management

“…18,987 ha -1 ) and BCR (1.64) were obtained from T 4 treatment where 80% STB from Inorganic fertilizer + 20% STB from CD i.e N-P-K-S-B (96-36-56-0-0.72) kg ha -1 + 20% from cow dung were used. Banerjee et al (2010) also agree with the above findings and stated the impact of different combined doses of fertilizers with plant growth regulators on growth, yield attributes and yield of mustard (Brassica campestris cv. B9).…”

Efficiency of Sulphur and Row Spacing on Growth and Yield Attributes of Mustard (Brassica campestris)

“…It is considered to be an important constituent of Indian diet and its oil is used as main cooking medium especially in northern India. Both the seeds and oil are used as condiment in the preparation of pickles and flavoring curries and vegetables (Banerjee et al, 2010).The cake obtained after the oil extraction is mostly used for cattle feed and manure. Mustard seeds are excellent source of minerals such as magnesium, calcium, potassium and phosphorus.…”

Influence of Sulphur Application on the Yield of Gobhi Sarson (Brassica napus L.)

“…Mustard seed has high nutritive value with protein content of 28-36%. Mustard a winter (rabi) season crop that requires relatively cool temperature, a fair supply of soil moisture during the growing season and a dry harvest period (Banerjee et al, 2010). In India, total area under mustard crop is 6652 thousand ha with production 7109 thousand tonnes (Anonymous, 2016-17) but the average yield of rapeseed-mustard in India is only 1145 kgha -1 (Economic survey, 2013) due to the lack of optimum use of nutrients particularly sulphur which is one of the important factors responsible for its low yield.…”
