Abstract

[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.

Abstract

[ORGANIC PRIMING FOR THE INVIGORATION OF DETERIORATED SORGHUM SEEDS (Sorghum bicolor (L.) Moench)]. Seed deterioration in new superior varieties (VUB) is one of the constraints in crop development, including sorghum Bioguma 3 Agritan. This study aimed to evaluate the effects of organic priming and soaking duration on the viability of deteriorated sorghum seeds. The experiment was conducted at the Seed Technology Laboratory of UPN “Veteran” Jawa Timur using a factorial completely randomized design with two factors, namely type of organic priming (sprout extract, spirulina extract, and combined extract) and soaking duration (6, 12, 18, and 24 h). The observed variables included germination percentage, maximum growth potential, fresh weight of normal seedlings, and dry weight of normal seedlings. The results showed that, in severely deteriorated sorghum seeds, priming with 10% mung bean sprout extract for 6 h produced the highest germination percentage, increasing germination by 97.17% compared with the untreated control, and gave the best result for maximum growth potential. This treatment was comparable to 10% spirulina extract for 12 h and combined extract (sprout extract +spirulina) for 12 h. The highest fresh weight of normal seedlings was obtained from 10% spirulina extract for 12 h, whereas dry weight of normal seedlings was relatively similar among treatments. Soaking for 24 h in all types of organic priming was not recommended because it tended to reduce the viability of deteriorated sorghum seeds.
