Farm Operations for January 1996

摘要

Apply second irrigation to wheat sown during November and first irrigation to wheat sown during December. To late sown wheat, apply remaining dose of N alongwith first irrigation. In light textured soils, where wheat follows paddy sulphur and manganese deficiency can be expected. Manganese deficiency causes intervenal chlorsis of the middle leaves. Such deficiency symptoms can be corrected with spray of 0.5% solution of manganese sulphate. Two sprays of 500 g MnSO_4 each at weakly interval may be done. The symptoms of sulphur deficiency are upper leaves become light green and then yellow while the lower leaves are still green. If such symptoms arc noticed, one quintal gypsum/acre may be broadcasted in the field and shallow irrigation may be given or if the soil is in proper moisture conditions, this may be mixed by hoeing.
