Abstract

An experiment has been designed to investigate the impact of Phosphorous (P) fertilizer on seed quaaliti during seed development of several Soybean (Glycine max L. Merrill) cultivars. The field experiment was carried at University of Riau Agriculture Experiment Station using a complete randomized block design with three replicates. Soybean cultivars such as Willis, Malabar, Kipas Putih and line KM-19-BE were planted in three rates of P fertilizer; ie P0 = 0 kg P2O5 as a control, P1 = 25 kg P2O5, and P2 = 50 kg P2O5 per hektare. Seed quality including seed viability and seed vigor was observed at 10 days interval from 20 to 50 days after anthesis (DAA). It was found that seed quality was very low at early stage of seed development and tent to reach its maximum value as seed matured. Addition of P fertilizer to the plant increased some components of seed quality at early stage of seed development until 40 DAA. The values of seed viability and seed vigor were higher in seed harvested from plant fertilized by P than control, mainly for seed obtained at early seed development. This results indicated that P fertilizer application would improve seed quality especially of seed harvested at early seed development of some soybean cultivars.

Abstract

Chilli (Capsicum annuum L.) is the one of vegetable commodities that has high economic value.Low productivity chili in Riau caused by several factors, including soil conditions mostly submarginal land such as peatland. This study aimed to obtain the performance chili hybrids from crosses between wrinkled chili and smooth chili that was grown in the peatland to be recommended as a genotype that has a high yield. This study used a randomized block design (RBD), consisting of 8 treatments (IPB C-111xIPB C5, IPB C-111xIPB C19,IPB C-120xIPB-C5,IPB C-120xIPB C-19,IPB C-159xIPB C-5, IPB C-159xIPB C-19, Tanamo, Biola) and 3 replications. The results of this study showed that 8 chili genotypeshad grown in peatland had different potentials between a genotype with others.All chilies genotype showed nonsignificant weight per plant compare to Tanamo and Biola. Genotype ofIPB C120xIPB C-5 is the highest yieldbecause had bigger stem diameter and highest fruit weigth. Keyword : Chili, Genotypes, Performance, Peatland.
