Abstract
The residual effects of various organic and inorganic fertilizers on the yield and nutrient uptake of groundnut cv. SB XI were studied in Parbhani, Maharashtra, India, during 1997/98 and 1998/99. The treatments, applied to cotton during the rainy season, consisted of NPK (T1; 100:50:50 kg/ha), farmyard manure (FYM; 25 t/ha), vermicompost (5 t/ha), neem seed cake (2 t/ha), pressmud cake (PMC; 25 t/ha) and glyricidia [Gliricidia] (10 t/ha) singly or in combination with Azotobacter (AZO) + phosphate-solubilizing bacteria (PSB), NPK + AZO + PSB + cowdung urine slurry (CDUS), FYM + PMC + glyricidia + AZO + PSB + CDUS (1/3 N through each of the first three sources) and 50% NPK through T1 + 50% NPK through FYM + AZO + CDUS + PSB (integrated nutrient supply system). N as urea (25 kg/ha) and P as single superphosphate (50 kg/ha) were applied to the succeeding groundnut crop during the summer season. The organic fertilizers along with the biofertilizers significantly enhanced the yield and nutrient uptake of groundnut. The integrated supply system resulted in the highest dry pod yield (2537 kg/ha); haulm yield (4388 kg/ha); haulm (60.4 kg/ha), hull (4.5 kg/ha) and total (139.6 kg/ha) N uptake; kernel (18.2 kg/ha), haulm (21.5 kg/ha), hull (1.6 kg/ha) and total (41.2 kg/ha) P uptake; and kernel (23.6 kg/ha), haulm (43.2 kg/ha), hull (3.8 kg/ha) and total (70.6 kg/ha) K uptake.
