EFFECT OF BALANCED NUTRIENT MANAGEMENT ON BLACKGRAM (Vigna mungo L.) IN RED AND LATERITIC SOILS OF WEST BENGAL

Abstract

A field experiment was conducted at Agricultural Farm of Palli Siksha Bhavana, Visva-Bharati, Sriniketan during pre-kharif 2015 to assess the response of balance fertilization on available nutrient status, yield, nutrient uptake and protein content of black gram in red and lateritic soils of West Bengal. The experiment was laid out in randomized block design with seventeen treatments. Results revealed that the highest seed, stover and biological yield were 12.76, 24.68 and 37.44 q ha -1 respectively recorded with combined application of macro and micronutrients along with FYM @ 5t ha -1 . The highest uptake of nitrogen (40.72 kg ha -1 in seed and 42.71 kg ha 1 in stover) and phosphorus (6.61 kg ha -1 in seed and 5.63 kg ha -1 in stover) was found in T 16 followed by T 15 . Similarly, highest uptake of potassium (10.61 kg ha -1 in seed and 9.54 kg ha -1 in stover) was found in T8 followed by T 16 and highest uptake of sulphur (4.25 kg ha -1 in seed and 7.65 kg ha -1 in stover) was found in T 4 followed by T 16 . Data regarding protein content in black gram was ranged between 16.45 to 22.42%. The balanced fertilization may be suggested for higher yield and nutrient uptake along with overall betterment.
