摘要

A 180-day field trial (Randomized Block Design) was carried out with 14 different treatments, using vermicomposts of Polyalthia longifolia leaf litter + cowdung (1:1, VC-PL), pearl millet cobs + cowdung (1:1, VC-PT) and a weed, Rottboellia exaltata +cowdung (1:1, VC-RE), chemical fertilizer and combination of vermicompost and chemical fertilizer with Lablab purpureus (L.) Sweet. The results of the study showed that all the growth and yield parameters i.e. leaf area index, total chlorophyll content of leaves, dry matter production, number of primary branches per plant, day of first flower appearance, length of fruits, dry weight of 100 seeds, yield (fruit) per plant, yield per plot and yield per hectare were significantly higher in the plots which received vermicompost, chemical fertilizer and vermicompost + chemical fertilizer mixture than in the control plots (P<0.05). The highest fruit yield (fresh weight) of 109 tonnes ha~(-1) was recorded in the treatment which received 2.5 tonnes of vermicompost (VC-RE prepared using Perionyx ceylanensis) + l/2 dose of recommended NPK ha~(-1), while it was 61.9 tonnes ha~(-1) in control plots without vermicompost and/or chemical fertilizer. The available soil nutrients (nitrogen, phosphorus and potassium) were higher in the plots which received vermicompost than in the plots that received chemical fertilizer and those that received chemical fertilizer + vermicompost mixture. The uptake of nutrients by the plants was high in the plots which received chemicalfertilizer + vermicompost mixture over the plots which received chemical fertilizer and vermicompost. The available NPK after harvest in soil collected from the plots treated with chemical fertilizers were 244, 32.9 and 100 kg ha~(-1) which were higherthan in the control plots and lower than in the plots that received chemical fertilizer + vermicompost mixture. The available NPK values in soil which received VC-RE prepared using P. ceylanensis + 1/2 dose of recommended NPK ha~(-1) were 262, 45.2 and 110 kg ha~(-1), respectively.
