Abstract:
An experiment was carried out to Investigne the effect of liquid organic fertilizer (named Ampthakaraisal) on dry matter content of groundout. The experimental design was randomized complete block design (RCBD) with three replications. Treatments were defined 35 follows: T- Recommended inorganic fertilizer application as control, T2- Amuthakaraisal applied at fifteen days. T3- Amuthakaraisal applied at fifteen and thirty days, T4 Amuthakaraisal applied at fifteen, thirty and forty- five days and T5: Amuthakaraisal applied at thirty and forty-five days. The results revealed that there were significant (p<0.05) differences in fresh and dry weights of stem and highly significant (p<0.01) differences in fresh and dry weights of pods and plant biomass among the treatments. The results showed that the plants responded best and gave higher biomass in T4 than that of the control. The dry weight of pods and total biomass increased by 22.99% and 26.36% respectively in Ta when compared to the control. The results indicated that continuous frequent application of Amuthakaraisal increased the dry matter content of groundnut. Application of Amuthakaraisal once in fifteen days could be practiced to increase dry matter production. From this study, it could be stated that, Amuthakaraisal application at fifteen days regular interval can be adapted by farmers in groundnut cultivation as it is less harmful to the environment and health.
