Integrated Application of Fertilisers and Biocane (Organic fertilisers) to Enhance the Productivity and Juice Quality of Autumn Planted Sugarcane (Saccharum officinarum L.)

University of Agriculture, Department of Agronomy, Pakistan

Abstract

An experiment was conducted to study the effect of different levels of fertilisers and biocane on the growth, yield and juice quality of sugar cane Var. SPSG-26 at the Agronomic Research Farm, University of Agriculture Faisalabad, Punjab, Pakistan during the year 2007-2009. The experimental design was a completely randomised block with four replications and a net plot size of 7.5 m × 7 m. The study comprised of five treatments viz. T1= N:P:K- 170:85:85 kg ha^-1, T2= biocane 2.5 l ha^-1, T3= biocane 2.5 l ha^-1 + N:P:K- 170:85:85 kg ha^-1, T4= biocane 2.5 l ha^-1 + N:P:K- 85:42:42 kg ha^-1 and T5= biocane 1.25 l ha^-1 + N:P:K- 170:85:85 kg ha^-1. All doses of P, K and ½ N was side dressed at the time of sowing and remaining ½ N was top dressed at the time of 3_rd irrigation while Biocane was sprayed as foliar fertilisers in December after seedling establishment. Cultivar SPSG-26 was used as test crop for this experiment.
All growth and yield parameters were significantly affected by biocane application along with synthetic fertilisers. Number of mill able canes, can length, can diameter, number of internodes per cane, internodal length, trash weight, weight per stripped cane, tops weight and stripped can yield were all significantly affected by the application of biocane 2.5 l ha^-1 + N:P:K- 170:85:85 kg ha^-1 (T3), as compared to the other treatments and is maximum cane yield (109.5 t ha^-1). The sucrose contents were non-significantly differed among all treatment means and varied between 7.7-12.78%.
The present study concluded that in case of sugarcane variety SPSG-26 the application of biocane 2.5 l ha^-1 + N:P:K- 170:85:85 kg ha^-1 proved give the highest cane yield. Integrated application of synthetic and biofertilisers can improve the soil physical conditions, microbial activity, plant growth and helps to sustain the environment, therefore, reducing the fertiliser pollutants in to the atmosphere and ground water.
