ABSTRACT
A field experiment was conducted to study the influence of organic manures and chemical fertilizers on yield, nutrient uptake by finger millet and soil fertility status at harvest during kharif 2013 at Agricultural Research Station, Perumallapalle, ANGRAU. The results revealed that significantly highest grain yield (37.21 q ha-1), protein content (8.82%), N uptake (84.80 kg ha-1), P uptake (12.04 kg ha-1), No. of tillers/plant (2.5), No. of fingers/ear head (13) were recorded in inorganic treated plot when compared with organic treated plot (35.08 q ha-1 of grain yield, 8.61% of protein content,75.29 kg ha-1 of N uptake, 11.58 kg ha-1 of P uptake, 2.2 tillers/plant, 11 fingers/earhead). Organic carbon content in soil was increased in organic plot (0.02% only) when compared with intial value. In both the treatments available N was reduced and available K was increased when compared with initial available N and K.
ABSTRACT
The study was carried out to investigate the effect of panchakavya made from cow (PK-C) and buffalo (PK-B) products on urease and dehydrogenase activity and root yield of Ashwagandha and it revealed that soil application of PK-C @ 15% recorded the highest urease activity at both the stages of crop (85.24, 44.56 at flowering and harvest during rabi 2007-08 and 81.07, 35.50 μg of NH4 + released g-1 soil h-1 at flowering and harvest in kharif 2008). The highest dehydrogenase activity also noticed in the same treatment (91.05, 49.05 μg of TPF g-1 soil day-1 at flowering, harvest during rabi 2007-08 and 81.00,, 39.64 μg of TPF g-1 soil day-1 at flowering, harvest in kharif 2008) during both the years. The highest dry root yield was recorded with PK - C @ 5% - 4 sprays (290 and 280 kg ha-1 during both the years, respectively).
