Growth, Yield and Biochemical Attributes of Pea With Sulphur Fertilization in Northern Indian Soil

Pea (Pisum sativum L.) plants were raised in Gomti upland soil (Lucknow). The soil, rated sulphur deficient on the basis of available soil sulphur, was fertilized with calcium sulphate to provide sulphur at the rate of 10, 25, 50 and 100 mg kg"¹ soil. Sulphur amendment at the rate of 50 mg kg"¹ soil induced maximum shoot length and dry weight production inpeaby 26.9 and 34.5%, respectively, whereas decreased with increasing S amendment in soil. S increased pod numbers, pod length and seed weight maximum at 50 mg kg"¹ sulphur amendment in soil. Pigments (chlorophyll a, b, total and carotenoids), sugar contents showed maximum values at 50 mg S kg'Hn soil. Therefore, study concluded that, S amendment at the rate of 50 mg S kg"¹ in alluvial soil may increase the growth and yield of pea.
