EFFECT OF AMELIORANT ON GROWTH AND YIELD OF RICE AT TIDAL PADDY FIELD

Rice (Oryza sativa L.) is the most important and strategic food crop in Indonesia, but low productivity in tidal paddy fields is a serious problem that must be overcome. The application of ameliorant would be worthy to increase the growth and yield of rice in tidal paddy fields. The study aimed to investigate the effect of ameliorant application on growth and yield of rice varieties in tidal paddy fields. The study was arranged in a split plot design with five replications. Rice varieties tested were Inpari 34, Dendang, Inpara 9, Inpari 35, and Ciherang as the main plot, and ameliorant types studied were humic acid, gypsum, zeolite, and organic fertilizer as the subplot. The results showed that the use of different rice varieties and amelioran types significantly increased the growth and yield of rice. Inpara 9 produced 7.6 t.ha-1 dry milled grain (DMG) or increased by 33.3% compared to Ciherang variety. Humic acid application at 25 kg ha-1 increased grain yield by 21.3% higher than that without ameliorant treatment. The best treatment to increase the growth and yield of rice in tidal paddy field was a combination of humic acid 25 kg.ha-1 and Inpari 34 which produced the DMG of 8.6 t ha-1 or 41% higher compared to Ciherang without ameliorant.

This research was aimed to determine the effect of tillage and varieties on rice growth and yield. This research used a Split Plot Design (SPD) where the land was cultivated (T) as the main plot and rice varieties as subplots (V) repeated three times. The main factors as the main plot consist of three levels, namely: without soil tillage (T0), minimum soil tillage (T1), and perfect soil tillage (T2). The second factor is 5 level varieties, namely: Tinggong (V1), Ciherang (V2), Cibogo (V3), Inpari-13 (V4), and Situ Bagendit (V5). Data were also projected onto principal component analysis (PCA) to observe differences and affected factors related to the soil tillage system. The results showed that the system of tillage had a very significant effect on the yield per hectare. There was no significant difference in yield between the minimum tillage and the perfect tillage. Variety had a very significant effect on plant height at eight weeks after planting (WAP), the number of tillers at 8 WAP, panicle length per clump, the amount of grains, percentage of full grain per clump, percentage of empty grain per hill, the weight of grain per panicle, weight 1,000 grain and yield per hectare. The Cibogo variety gave the highest yield, namely 4.86 ton/ha. Based on PCA analysis, plant height, the total amount of grain, and filled grain are highly affected by the soil tillage system.

Percobaan penambahan N pada POC sebagai foliar fertilizer untuk tanaman padi ratoon telah dilaksanakan Di Kota Padang, September 2017 - Januari 2018, Tujuan penelitian mendapatkan kombinasi dari pemberian Nitrogen buatan terhadap POC untuk meningkatkan pertumbuhan dan hasil padi ratoon. Percobaan disusun dalam bentuk split plot, dengan petak utama adalah pemangkasan terdiri atas 2 taraf yaitu; tidak dipangkas dan dipangkas. Anak petak berupa pemberian foliar fertilizer terdiri atas 4 jenis yaitu; 0 (F1); 800 mg L-1 Urea (F2); 25 ml L-1 + Urea (F3); 50 ml L-1 POC + Urea (F4), diulang 3 kali. Data dianalisis secara statistika menggunakan ANOVA α 5%, jika perlakuan berpengaruh nyata dilakukan dengan uji lanjut BNT α 5%. Parameter antara lain; berat hijauan pangkasan, tinggi tanaman, persentase anakan produktif, umur berbunga dan panen, produksi jerami dan gabah per hektar. Dari hasil percobaan maka disimpulkan bahwa pemberian 800 mg L-1 pupuk N tunggal dari Urea atau menambahkannya ke dalam POC tidak menguntungkan bagi pertumbuhan dan hasil padi ratoon. Pemangkasan tidak menurunkan hasil gabah yang mencapai 5,37 t ha-1 GKP, dan peroleh usaha tani masih dapat diimbangi dengan adanya HPT sebesar 3,63 t ha-1 yang sangat penting bagi program integrasi padi dan ternak. The experiment of an addition of N on foliar fertilizer for ratoon rice plant has been done In Padang City, September 2017 to January 2018, in a semi-intensive paddy field, with altitude 10 m above sea level. The experiment was arranged in the form of a split plot, with the main plot being a pruning consisting of 2 levels ie; not pruned and. The subplot of fertilizer foliar consists of 4 types namely; 0 (F1); 800 mg L-1 Urea (F2); 25 ml L-1 + Urea (F3); 50 ml L-1 POC + Urea (F4). Experiment repeated 3 times. Data were analyzed statistically by using ANOVA 5% if treatment had real effect done with BNT test 5%. Parameters include; the weight of crop forage, plant height, a percentage of productive tillers, flowering age and harvest, straw and paddy production per hectare. From the experimental results, it was concluded that administering 800 mg L-1 of single N fertilizer from Urea or adding it to POC as foliar fertilizer was not favorable for growth and yield of ratoon rice. Pruning does not reduce grain yield reaching 5.37 t ha-1, and earn farming can still be offset by the existence of HPT of 3.63 t ha-1.
