Transplant, K, B, and Prunning on YIELD of Physalis Peruviana L., in Hydroponics and Greenhouse.

Physalis peruviana L., is a plant native to Peru and Chile, its future as a commercial crop depends on climatic conditions and the crop technology level used. The objective of this research was to study the effect of the date of transplant, supply of potassium (K), boron (B) and pruning on the fruit quality and yield of Physalis peruviana L., growing without soil and in a greenhouse. We utilized plants of the variety Colombia. The experimental design was a split plot with three replications; large plot corresponded to transplant dates (18 June, 18 July and 17 August 2013, respectively) and small plots were agronomic practices resulting from the combination of the foliar spray with B (0, 1, 3, L^-1 mg), K (3.5 and 7, meq L^-1) and pruning (3 stems and multi-stems). During two months of harvest we quantified the accumulated fresh weight per plant, fresh weight of fruits with (FWC) and without calyx (FWWC), the number of fruit (NF), the average weight of fruit (AFWF) and the number of cracked fruit (NCF). The date of transplant and B influenced all the variables studied, and pruning only affected the NCF. Potassium had no effect on the evaluated variables. The highest yield in FWC, FWWC, NF, and NCF was the second date of transplant with 3 mg of B L^-1 and 3.5 L^-1 meq of K in plants with and without pruning. The higher average weight of fruits was reached in the third date of transplant and the lower NCF was observed in the second and third date of transplant with 3.5 L^-1 meq of K and 1 mg L^-1 of B in plants without pruning.
