FOLIAR APPLICATION OF NUTRIENTS ENHANCES THE YIELD ATTRIBUTES AND NUTRIENT UPTAKE OF GREENGRAM
1Department of Agronomy,

ABSTRACT
A field experiment was conducted at Tamil Nadu Agricultural University farm during summer season in 2005 to evaluate the effect of foliar application of nutrients on the yield and nutrient uptake of greengram. Foliar spray of nutrients (urea, DAP and sodium molybdate) and growth regulator (Salicylic acid) were sprayed as individual and in combination at vegetative and flowering stages. Combined application of 2%DAP+100 ppm salicylic acid+0.05% sodium molybdate increased the yield attributes [fertility coefficient 35.99%, partitioning coefficient (49.18%) per plant and grain yield 928kg, haulm yield 1230kg per ha] followed by 2%urea+100ppm salicylic acid+0.05 sodium molybdate treatment. Similar trend was observed in nutrient uptake (N, P and K) also.
