Abstract

This study aims to determine the effect of fruit pruning and application of Potassium on the growth and production of strawberry plants (Fragaria chiolensis). This study used a randomized block design (RBD) with 2 factors. The first factor was fruit pruning consisting of 4 levels: P0 = No pruning, P1 = 1 pruning, P2 = 2 pruning, P3 = 3 pruning. The second factor is Potassium fertilizer consisting of 4 levels: K0 = 0 g/plant, K1 = 2 g/plant, K2 = 4 g/plant, K3 = 6 g/plant. The observed variables were plant height (cm), flowering age (days), Fruit Weight (g), Fruit Volume (cm3), Sugar Content (%), Plant Wet Weight (g), and Plant Dry Weight (g). The results showed that pruning three fruits/plant increased plant height, fruit weight, fruit volume, sugar content, fresh weight and dry weight. Applying potassium fertilizer up to a dose of 6 g/plant can increase plant height, flowering time, fruit weight, fruit volume, sugar content, and wet and dry weight. Meanwhile, the interaction between fruit pruning and potassium application had no significant effect on all observed parameters.

Abstract

This research aims to determine the effect of a combination of NASA POC and chicken manure on the growth and production of sweet corn (Zea mays saccharata Sturt). The research used a Randomized Group Design (RAK) with two treatment factors. The first factor is the administration of NASA Liquid Organic Fertilizer (A) consisting of 4 treatment levels, namely: A0 = 0 ml/liter of water (control), A1 = 2 ml/liter of water, A2 = 4 ml/liter of water and A3 = 6 ml /liter of water. The second factor is the provision of chicken manure (B) consisting of 3 treatment levels, namely: B1 = 2.25 kg/plot (7.5 tons/ha), B2 = 4.50 kg/plot (15 tons/ha) and B3 = 6.75 kg/plot (22.5 tons/ha). The results showed that giving NASA POC up to 6 ml/l of water significantly increased plant height, ear length, ear weight per plot and total dissolved solids. Providing chicken manure up to 6.75 kg/plot significantly increased plant height, ear length, weight per plot and total soluble solids. The interaction between NASA POC and chicken manure did not significantly affect plant height, ear length, weight per plot, or total dissolved solids.
