TABLE NO.41: Score to record Phytotoxicity (%)
The phytotoxicity observations of tested liquid formulation product for the doses specified in protocol in taken as per rating criteria at 1, 3, 5, 7 and 10 days after application of nano-particulate liquid formulation product was recorded. The observations are taken on specific parameters like chlorosis, necrosis, wilting, scorching, hyponasty and epinasty were recorded and presented in respective tables. ii) Growth Parameters: Average plant height (cm):Plant height recorded from randomly selected five plants of each treatment and then the average value was calculated. Height of plant was measured in centimeter from the ground level to the tip of fully opened leaf. Number of branches per plant:The count of number of branches was taken from randomly selected five plants and average value of branches of five randomly selected five plants was calculated and expressed as average number of branches of pod per plant. Spread of plant: The maximum spread of the plant in East-West and North-South directions were recorded in centimeter. Mortality (%):The count of total number of plant and number of died plant in each net plot were recorded. The percent mortality was calculated by using formula. Mortality (%)= No. of died plants per net plot ------------------------------------------- x 100 Total no. of plant per net plot. Yield (q/ha): The weight of fruits harvested in each picking from each net plot were recorded and totaled up plot wise to get yield per plot. This was converted hectare basis. Number of effective root nodules at flowering stage:Uprooted the selective plants carefully and removed the soil by tap water. Count each effective root nodules per plant. Yield attributes and yield studies: Five plants were randomly selected from each net plot for post-harvest studies such as number of pods plant -1 , weight of pod -1 , grain weight plant -1 , test weight (g), grain and straw yield (q ha -1 ). Number of pods plant -1 : All the pods from five randomly selected plants were counted separately after harvest and the average number of pods plant-1was worked out. Weight of pods pod -1 (g.): At harvest, the weight of pods of five observational plants was recorded. Then weight of pods plant-1 was worked out. Grain weight plant -1 (g.): The total grains obtained from every observation plant were weighed separately on analytical weighing balance and mean value was calculated for obtaining the weight of grains (g.)green pod weight of five randomly select plants was recorded from each plot. Test weight (g): From the composite seed of net plot 100 seeds were counted and weighed on analytical weighing balance and values were recorded. Grain yield (q ha -1 ): The produce was dried in sun for a week. After harvesting, the grains were cleaned of dried leaves, soil and other foreign material. The grain yield net plot -1 was recorded and then converted on hectare basis by multiplying with hectare factor. Straw yield (q ha -1 ): After removing the grain from pods, the stalks along with empty pods were dried in the sun. Upon drying, the weight of the bundle of stalk per plot was recorded. the weight per plot was transformed into hectare basis by utilizing hectare factor.

D T Ta45ta of plant height four days after first spray was found to be non significant indicating uniform plant height in all treatments. Data of plant height at 5 and 9 days after first spray and second spray showed that the spraying of N:P: K- 21:21:21@ 2 ml/ lit of water (T 3 ) and spraying of N:P:K-21:21:21@ 1.5 ml/ lit of water (T 2 ) were found to be the best treatment for producing taller plant and both the treatments were significantly superior over rest of the treatments and remained statistically with each other. Similar trend was observed at the time of last picking. TABLE NO.110: Effect of N P K-21:21:21 liquid fertilizer on number of branches per plant). T1
Data of number of branches per plant are presented in above table. Four days before spraying number of branches did not differ significantly due different treatments, indicating statistically uniform number of branches in all the treatments. An analysis of data showed that at 5 and 9 days after first and second spraying of N:P:K-21 :21 :21@ 2 ml/ lit of water (T 3 ) and spraying of N:P:K-21 :21 :21@ 1.5 ml/ lit of water (T2) recorded significantly more number of branches over rest of the treatments under study and both these treatments were statistically at par with each other except at 5 days after first spraying, where treatment T 3 was significantly superior over treatment T 2 . At the time of last picking the treatment T 3 and treatment were significantly over rest of the treatments.

• Yield (q/ha) :The mortality percentage and fruit yield of green chili as affected by the different treatments is presented in below table.
TABLE NO. 113: Mortality percentage and fruit yield of Green Chili as affected by different treatments. Data presented in above tables that indicates that the treatment N:P:K-21 :21 :21@ 2 ml/ lit of water (T3) were recorded lowest mortality percentage of mortality followed by the treatment spraying of N:P:K-21:21:21@ 1.5 ml/ lit of water (T2). Highest mortality was observed in control treatment T4. A close examination of data presented in above table shows, that the treatment N:P:K-21:21:21@ 2 ml/ lit of water (T 3 ) and spraying of N:P:K-21:21:21@ 1.5 ml/ lit of water (T2) were found to be the best treatments for producing maximum fruit yield of green chili and both the treatments were significantly superior over rest of the treatments and remained statistically similar with each other. The treatment spraying of liquid fertilizer N:P:K-21:21:21@ 2 ml/ lit of water (T3) and spraying of N:P:K-21:21:21@ 1.5 ml/ lit of water (T2) was registered 31.60 percent and 29.98 percent increase in yield over control treatment respectively. Conclusion: On the basis of field experimentation conducted for evaluation of bio- efficacy of N:P:K-21:21:21 liquid fertilizer as per present invention on chili crop during summer season, it was concluded that both the treatments N:P:K-21:21:21@ 2 ml/ lit of water (T3) and spraying of N:P:K-21:21:21@ 1.5 ml/ lit of water (T2) were found to be the best treatments for improving plant growth and yield of chili as compared to the other liquid fertilizer. Hence, the present invention is developed to give better and effective fertilizer composition for good health of plant and its yield. The present invention provides a nanoparticle-based formulation of NPK liquid fertilizer having 100% water solubility which increases absorption rate of nutrients into the plant, which comprising of sufficient primary nutrients as well as micronutrients for crop management with cationic liquid, water-soluble fertilizer composition without undesirable alkali content such as Sodium (Na) and Chlorine (Cl) at neutral pH for maximum plant availability of Nitrogen, Phosphorous and Potassium source.
