Abstract

Low soil fertility can constrain the paddy red rice yield. One of the efforts to increase paddy red rice production at the Tidal swamp area is using iron toxicity tolerant varieties. The objectives of this research were (i) to evaluate the agronomic responses of red paddy rice to low nutrient supply to determine the sensitive character and (ii) to identify the tolerant and nutrient-efficient variety under low nutrient supply in a tidal swamp area. The experiment was conducted at Tidal Swamp Area Type B, Telang Sari Village, Banyuasin District, South Sumatra Province. The experimental design was Split Plot with five replications. Nutrient supply was the main plot, and the Varieties (Inpara 7; Inpago 7, Aek Sibundong, and Telang Sari) were the subplot. The nutrient supply treatments were H1: standard fertilizer rate and H2: low nutrient supply, which is 30% of the standard rate. The results showed that Inpago 7 and Inpara 7 were potential varieties at low nutrient supply. The sensitive characteristics of the varieties evaluated were chlorophyll content, number of tillers, grain weight, and percentage of empty grain for growth and production characters.

Abstract

This study aims to obtain the right dosage of nitrogen and potassium fertilizers as well as the interaction between nitrogen and potassium in increasing the growth and yield of sweet corn (Zea mays var. saccharata). This study used a factorial randomized block design consisting of 2 treatment factors, namely nitrogen and potassium fertilizer treatment, with 3 replications. Factor I Nitrogen fertilizer treatment with the dose: N0: Without nitrogen fertilizer (control), N1: Nitrogen fertilizer 150 kg/ha Urea, N2: Nitrogen fertilizer 300 kg/ha Urea. Factor II Potassium Fertilizer : K0 : Without Potassium Fertilizer (control), KI : Potassium Fertilizer 200 kg/ha K2O, K2 : Potassium Fertilizer 300 kg/ha K2O. The parameters observed in this study were plant height (cm), cob length (cm), cob weight (grams), cob diameter (grams) and dry chestnut weight (grams). The results of the analysis of variance showed that the treatment of nitrogen fertilizers and potassium fertilizers had a significant to very significant effect on all observed variables. The interaction of nitrogen and potassium fertilizers had a significant effect on cob weight and had a very significant effect on plant height, cob diameter and dry matter weight and had no significant effect on cob length.
