Research on the closed insulated pallet system (CIPS) has shown that it is a promising growing technique for the protected agriculture. CIPS is based on a continuous sub-irrigation capillary system. It is simple, high water and fertilizer use efficient, many of its components are recyclable, requires low resource inputs such as labor and overall it is an environmentally friendly system. Because fertilizers are applied once at the beginning of planting any crop in CIPS, optimization of fertilizer type of appropriate solubility is of a great importance for the system. Therefore, the objective of the present study was to evaluate two fertilizers of different solubilities for growing chili pepper (Capsicum fructescens ‘Sahem’) and Cherry tomato (Lycopersicon esculentum ‘Super Sweet 100’). A factorial experiment with two fertilizers standard Nitrophoska Blau and slow release Osmocote Exact was conducted. Results showed that chili pepper vegetative growth and yield were significantly greater when fertilized with the slow release fertilizer than the standard fertilizer. No marked difference was observed between the two treatments with reference to plant height and leaf number in cherry tomato. However, more number of fruits and total weight of fruits produced per plant were obtained in plants treated with standard fertilizer. Average size of fruit was similar in both fertilizer treatments. It is concluded hat selection of the fertilizer type in terms of solubility can be crucial in CIPS for growing chilli pepper and cherry tomato in protected environment.
