Canola (Brassica napus L.) is an important edible oilseed
crop in the World and Pakistan. It has a healthy vegetable oil because of its
balance with omega 3-6-9 essential fatty acids, making canola oil a healthy
vegetable oil throughout the World for the cooking and processed food industry.
Nitrogen, phosphorus and potassium (NPK) are some of the major nutrients
required to significantly increase canola yield. A high-yielding canola
production needs a well-balanced fertilization program. In Pakistan, the
production of oil seed crops with their nutrition values could not be enhanced
in accordance with domestic edible oil needs. Canola is consumed as vegetables
and its edible oil is used for cooking. The agronomic and nutritional values of
vegetable oils are dependent on the nature of fertilizers that are added to the
soil. An experiment was launched to check the impact of various fertilizer
combinations on two canola varieties at the Agronomic research area of Gomal
University, Dera Ismail Khan, Pakistan. RCBD with a split-plot arrangement,
having three replicates were used for the study. PARC canola (hybrid) and
Faisal canola (open-pollinated) cultivars were kept in main plots, whereas
various fertilizers NPK (120:60:60 kg ha-1). Rustam organo (125 kg ha-1), Bio
care (125 kg ha-1), H R care (125 kg ha-1), Ferti source (125 kg ha-1), NPK +
Rustam organo, NPK + Bio care, NPK + H R care, NPK + Ferti source and control
(no fertilizer used) were assigned to sub-plots. The yield and yield components
of canola were significantly affected by using different fertilizers and
varieties. Grain yield and its components were found to be maximum in PARC
hybrid Canola with NPK applied @ 120:60:60 kg ha-1. Use of organic manure
(Ferti source) + half NPK (60:30:30) kg ha-1. With PARC hybrid produced
statistically at par results in comparison of in-organic manure. Data also
demonstrated that the balanced fertilizer application of NPK either organic or
inorganic ensures good quality proteins and high values of linoleic acids such
as alpha linoleic acid and gamma linolenic acid in canola oil content. In
conclusion, this experiment also showed that the application of organic manures
had a significant impact on canola nutrition, canola yield and soil health by
increasing organic matter in the soil.
