Abstract
Fertilizers application plays an important in the production of fruits and vegetables. Over-application of fertilizers can slow down the growth and development of fruits and vegetables. The present research work was carried out to check the yield and growth rate of carrot in open field by using drip irrigation along with the application of different rates of poly-feed water soluble NPK(20-20-20) fertilizer. The field study was carried out on randomized complete block design (RCBD) having four different rates of poly-feed water soluble NPK fertilizer, i.e. (T0 = control, T1 = 0.7 grams per plant fertigation-1, T2 = 1 grams per plant fertigation-1, and T3 = 1.4 grams per plant fertigation-1) respectively. All the data analysis and statistical analysis for agronomic parameters were done through ANOVA procedure accordingly. The outcome of the conducted research tantamount that the poly-feed water soluble NPK(20-20-20) fertilizers application with different rates brought a positive effect in carrots cultivation under the open field arrangements. Amongst different treatments rates of NPK, treatment T3 was observed to be more suitable and economical dose as it took the tallest carrot plants (44.67cm), highest number of leaves (5.52), highest leaf length (44.38 cm), the highest root core diameter (1.76 cm), maximum root shoulder diameter (5.09 cm), highest root length (19.11 cm) and highest root yield (11.07 t/ha) respectively. However, control plots showed un-satisfactory results regarding all the parameters. Therefore, from the current study it may be concluded that application of NPK(20-20-20) (treatment T3 = 1.4 grams / plant fertigation-1 were suitable for optimum growth and yield of carrot. Application of fertilizers beyond this level seems to be an un-economical and wasteful practice. Statistical analyses of all the research parameters are elaborated in Table I.
