Abstract:
The present investigation entitled “Comparison of balanced nutrition and farmer’s fertilization practice using rice as a test crop on tribal farmer’s field” was conducted in 2020 at Telgara village, Kanker, C.G. The experiment was laid out in independent t-Test having two treatments, which replicated twenty times. The treatment consisted of two different treatments viz. T1: Farmer’s fertilizer dose [N:P2O5:K2O::65: 46: 30 (kg/ha)], T2: Balanced fertilizer dose [N: P2O5: K2O: 120: 60:40 (kg/ha)]. The experiment was conducted under tribal sub-plan (TSP) of AICRP on Long Term Fertilizer Experiment (LTFE). The LTFE has been continued since 1999 at Raipur and amongst 10 treatments of LTFE after 2 decades of experimentation, the optimum balanced (N: P2O5: K2O: 120: 60: 40 kg/ha) recommended dose of nutrients for rice crop had been identified as an optimum treatment to produces sustainable rice yield without compromising the soil properties. To aware the farmers of Kanker district, this sustainable balanced dose of nutrients treatment had been introduced to compare the yield gaps between 2 treatments or indirect approaches to increase the farmer’s income through an increase in rice yield. With this idea and/or aim the present experiment was framed with a specific and minimum set of treatments on rice crop during the Kharif season.
As regards the effect of fertilization on Physicochemical properties of soil such as pH, EC & OC recorded significant differences among each other. The farmer’s practice dose (FPD) had a mean value of pH (6.33), EC (0.14 dSm-1) & OC (0.67%) and balanced fertilizer dose (BFD) had the mean value of pH (6.22), EC (0.13 dSm-1) & OC (0.69%) was noted amongst 20 farmer’s fields.
The data on major nutrient content in the soil revealed that the available N was significantly differed and recorded the highest (252 kg/ha) available N in BFD and the lowest (223 kg/ha) value was recorded under the FPD. The available phosphorus significantly increased among the treatments (FPD & BFD) and ranged from 11 to 14 (kg/ha). The significantly higher available P (14 kg/ha) was recorded in BFD and lower available P (11 kg/ha) was noted in FPD. Similarly, higher available K (419 kg/ha) was recorded in balanced fertilizer dose (BFD) and lower available K (302 kg/ha) was noted in farmer's practice dose.
The data recorded on micro-nutrient status in soil showed non-significant differences among both (FPD & BFD) treatments. The available Cu varied from 0.82 to 0.89 (mg/kg) in FPD and 0.83 to 0.89 (mg/kg) in BFD amongst 20 farmer’s field. The available Fe varied from 10.2 to 10.9 (mg/kg) in FPD & 10.0 to 10.9 (mg/kg) in BFD amongst 20 farmer’s field. The available Mn ranged from 7.2 to 7.9 (mg/kg) in FPD and 7.0 to 9.9 (mg/kg) in BFD amongst 20 farmer’s field. The highest (0.90 mg/kg) total Zn content was recorded in balanced fertilizer dose (BFD) and the lowest (0.80 mg/kg) total Zn content was recorded in farmer's practice dose (FPD) in farmer’s field.
The effect of fertilization on harvesting index of rice ranges from 41.88 to 43.65 (q ha-1) among the treatments balanced fertilizer dose (BFD) and farmer’s practice dose (FPD). The harvesting index of rice was significantly influenced. The highest H.I. (43.65 q ha-1) of rice was obtained with the application of FPD which was significantly superior over the treatment BFD (41.88 q ha-1).
