Effect of different level of NPK and sulphur on soil physico-chemical properties and yield of Mustard (Brassica juncea L.) var. Shikar

Abstract

The investigation on “Effect of different level of NPK and sulphur on soil physico-chemcial properties and yield of mustard ( Brassica juncea L.) var. Shikar ” comprise of a field experiment which was carried out at the Soil Science Research Farm, Sam Higginbottom University of Agriculture Technology, Prayagraj during zaid season 2023. It is situated at 25 0 40 ’ 92 ’’ N latitude, 81 0 84 ’ 93 ’’ E longitude and at the altitude of 98 meter above the sea level. The maximum temperature of the location reaches up to 46-48 °C and seldom falls as low as 4-5 °C. The relative humidity ranged between 20 to 94 percent. The average rainfall in this area is around 1100 mm annually. The experiment was conducted in randomized block design with different level of NPK and Sulphur. The treatments were replicated three times and were allocated at random in each replication. On the basis of findings it is concluded that the treatment combination @ 100% NPK + @ 100% Sulphur i.e, Treatment T 9 shows best result on growth and yield of mustard ( Brassica juncea L.) var. Shikar in comparison to other treatment combination. Since the findings are based on the research done in one of season further experiments with more than one season will help in better to study the effect of different levels of NPK and sulphur on growth and yield by mustard ( Brassica juncea L.) var. Shikar. The minimum bulk density (Mg m -3 ), particle density (Mg m -3 ), pH and EC (dSm -1 ) was noted in @ 100% NPK + @ 100% Sulphur which was significantly superior over T 1 Control. Whereas The maximum pore space (%), organic carbon, available nitrogen (kg ha -1 ), available phosphorus (kg ha -1 ) and available potassium (kg ha -1 ) and sulphur (ppm) was noted in @ 100% NPK + @ 100% Sulphur which was significantly superior over T 0 Control.
