Description |
A field experiment was conducted on a sandy loam soil (Alfisol) at fields of AICRP on Forage Crops, LRI, Rajendranagar, Hyderabad during kharif and rabi, 2007-08. The objective was to study the effect of biogas poultry manure(BPM), a byproduct of poultry manure based biogas unit, on performance of maize and its residual effect on forage cowpea. In this study, the recommended dose of N to maize was replaced by BPM and PM to the extent of 50, 75 and 100 per cent and applied to soil to study its effect on yields of maize and cowpea, crude protein contents and soil available nutrient status at harvest of both crops. The experiment was laid out in randomised block design and replicated thrice. Dekalb super 900, a maize hybrid was grown during kharif under different levels of N replacement through BPM and PM and during rabi cowpea was grown purely on residual fertility. The biogas poultry manure (BPM) was collected from poultry manure based Biogas Unit at Department of Poultry Science, Rajendranagar, Hyderabad, whereas poultry manure (PM) was acquired from the poultry farm of AICRP on Poultry, LRI, Rajendranagar. Cob, seed and stover yields of maize significantly increased with increasing level of biogas poultry manure (50.31, 40.73 and 39.54 q ha-1, respectively). Yields were maximum in treatment receiving 100 per cent N through BPM and the stover yield of maize was maximum at 50 per cent N through PM treatment. The BPM receiving treatments significantly influenced higher cob, seed yield and seed protein content of maize, whereas PM receiving treatments increased stover yield and stover protein content of maize. Maize seed and stover crude protein which is the most important parameter in animal nutrition increased significantly with increase in manure application. The maximum crude protein in seed (%) was recorded in treatment receiving 100 per cent N through BPM, whereas stover crude protein content was the highest in 75 per cent N through PM treatment. The major and micronutrient composition and uptake in maize seed and stover significantly increased with increasing application of manure (BPM and PM). The higher values of N, P, K, Fe, Mn, Cu and Zn in seed were recorded in BPM treated plots, i.e., the treatment receiving 100 per cent N through BPM recorded 76.51, 20.66 and 22.02 kg ha-1 of major nutrients and 48.88, 52.13, 16.29 and 87.16 g ha-1 of micronutrients, respectively. The higher concentration of N and P (0.35% and 0.04%) were recorded in PM treated plots i.e., T6 and T7 (75% and 100% N through PM, respectively) treatments, whereas the K concentration was the highest in BPM treated plots. The cowpea (grown on pure residual fertility) which was harvested at 50 DAS, at flowering stage recorded maximum green fodder and dry matter yields in treatment receiving 100 per cent N through PM during previous kharif. Hence, it could be concluded that the performance of maize was best when 100 per cent N was applied through BPM, whereas in cowpea grown on residual fertility the 100 per cent N through PM treatment gave the highest green fodder yields. The highest protein content was recorded in PM treated plots, though the increase was non-significant. In cowpea, the nitrogen and phosphorous concentrations (%) were not significantly influenced, but potassium (%) was higher in PM treated plots due to slow release of nutrients from poultry manure. The uptake of N, P, K and micronutrients were significantly higher in PM treated plots and maximum values recorded in 100 per cent N through PM treatment. The major nutrient uptake in maize was in the order of BPM treatments > PM treatments, whereas micronutrient uptake of maize was higher in PM treated plots. It is interesting to note that cowpea crop (grown on residual fertility) has recorded significantly higher values of micronutrients with application of manures. The highest Fe, Mn and Cu concentrations (ppm) were recorded in PM treated plots except Zn which was the highest in 100 per cent N through BPM treatment. Effect on soil physico-chemical properties (pH, EC and OC) after harvest of both crops (kharif maize and rabi cowpea) was non-significant. Available nutrient (N, P, K, Fe, Mn, Cu and Zn) status after maize crop significantly increased with increasing application of manures (272.93, 46.83 and 226.99 kg ha-1 of major nutrients and 17.48, 63.39, 2.32 and 4.79 mg kg-1 of respective micronutrients). The available status of N and P2O5 were maximum in PM receiving treatments, whereas, available status of K2O, Cu and Zn were maximum in BPM receiving treatments. In case of residual effect on cowpea, the available status of major nutrients N, P2O5 and K2O were significantly higher in PM treated plots. The available status of Fe and Zn was the highest in BPM treated plots except Cu and Mn which were not significantly influenced. |
