[EFFECT OF PHOSPHORUS FERTILIZATION AND Clitoria ternatea LEGUMINOUS GREEN MANURE ON
THE GROWTH AND YIELD OF ARUMBA WAXY CORN (Zea mays Ceratina var. Arumba)] Food security and
resilience can be achieved through diversifying local food products, for example waxy corn (Zea mays Ceratina). The potential yield of this commodity can be increased through fertilization, either chemically using phosphorus fertilizer or organically using Clitoria ternatea leguminous green manure. This study aimed to obtain the interaction between P fertilization and Clitoria ternatea leguminous green manure on the growth and yield of Arumba waxy corn. This study is a factorial experiment arranged based on a Randomized Block Design (RBD). The first factor is phosphorus fertilizing, consisting of 3 treatment levels; the second is Clitoria ternatea leguminous green manure fertilizing, consisting of 2 treatment levels. The results of the study showed that the combination of 50 kg/ha phosphorus fertilization and without Clitoria ternatea leguminous green manure gave the best results on plant length at 14, 21, and 28 DAP; stem diameter at 7 and 28 DAP, cob diameter with husk, cob weight with husk, cob weight without husk, and total fresh weight of Arumba waxy corn. The single treatment of P fertilization had a very significant effect on plant length at 35 DAP and stem diameter at 7 and 28 DAP, and had a significant impact on stem diameter at 35 DAP. Based on the results of the study, phosphorus fertilization at a rate of 50 kg/ha is recommended for the cultivation of Arumba waxy corn, as it resulted in the highest yield during the generative growth phase.

[GENETIC VARIABILITY AND HERITABILITY OF 10 ACCESSIONS OF BIRD’S EYE CHILI (Capsicum frutescens L.) GROWN ON COASTAL LAND]. Cultivation of bird’s eye chili (Capsicum frutescens L.) on saline coastal land in Indonesia faces several environmental constraints. Efforts to increase bird’s eye chili productivity in saline land are by planting varieties that are adaptive to stressed environmental conditions. This research aims to evaluate performance, estimate genetic diversity and heritability of agronomic traits in 10 bird’s eye chili accessions in coastal land in Kuala Alam, Bengkulu. The research was conducted using a one-factor Randomized Complete Block Design (RCBD) with 10 accessions as treatments and three replications. The results showed that the characters of plant height, stem diameter, flowering date, dichotomous height, fruit length and fruit diameter had wide genotypic variation. Broad phenotypic was shown by all characters. High heritability values were obtained in the characters of plant height, stem diameter, flowering date, dichotomous height, number of dichotomous points, fruit length and fruit diameter. The characters of number of leaves, leaf greenness, number of fruits per plant and fruit weight per plant have medium heritability values. The number of stomata and stomatal density characters have low heritability values. Accession Bangka 2 has superior performance in the characters of plant height, stem diameter, flowering date, dichotomous height, number of dichotomous point, fruit length, fruit diameter and fruit weight per plant. Accessions with superior performance and characters that have high heritability values with a wide genotypic and phenotypic range are used as elders in plant breeding programs. These findings form the basis for the development of superior bird’s eye chili varieties that are adaptive to saline land.
