Abstract

The field experiment to study the effect of microgranular sulphur (Cosavet Ferits WG) on soil properties, nutrient uptake, growth and yield parametes of banana was undertaken at Banana Research Station, Jalgaon during the years 2007 to 2009. Application of sulphur @ 12 g plant^-1 through Cosavet Fertis (WG) in two splits recorded significantly higher no. of hands per bunch, maximum bunch weight and yield over control. Application of sulphur @ 9 g plant^-1 through Cosavet Fertis (WG) in two splits recorded 137 fingers per bunch, 19.6 kg bunch weight and 87.0 t ha^-1 yield which was found at par with application of sulphur @ 12 g plant^-1 through Cosavet Fertis in two splits. Lower soil pH and EC were reported in the treatments where sulphur was applied through Cosavet Fertis (WG). Higher nutrient uptake was recorded in the treatment of sulphur @ 12 g plant^-1 through Cosavet Fertis (WG) in two splits.

Abstract

Field experiment was conducted at Banana Research Station, Jalgaon (M.S.) to find out the amount of N and K2O which can be fed through drip irrigation for banana and the effect of fertigation on soil properties, nutrient uptake and yield of banana cv. GRAND NAINE. Application of 75 % recommended dose of N and K₂O through drip at weekly interval in 44 splits up to 300 days and recommended dose of P₂O₅ by soil placement at the time of planting, found beneficial in terms of banana yield and monetary returns, indicating 25 % saving in N and K fertilizers due to use of fertigation technique. Uptake of nutrients was increased in the fertigation treatments as compared to the conventional method of fertilizer application.

Abstract

A Field experiment was conducted at Banana Research Station, Jalgaon (M.S.) to find out effect of different sources of nitrogen on soil properties, nutrient uptake and yield of banana cv. Grand Naine under drip irrigation. Combined application of 25 % N through urea + 50 % N through ammonium sulphate + 25 % N through calcium ammonium nitrate was found beneficial in terms of banana yield and monetary returns. Which was followed by application of 100 % N through ammonium sulphate. Lowest plant height, stem girth, no. of hands per bunch, no. of fingers per bunch, bunch weight and yield was recorded in the treatment of application of 100 % N through calcium ammonium nitrate. The pH and electrical conductivity after harvest of banana decreased slightly in the treatments where ammonium sulphate was used as source of nitrogen as compared to other N sources. Organic carbon and available N, P and K content of soil was not much influenced due to use of different sources of nitrogen.
