ABSTRACT The aim of the research was to studied the application of gliricidia MOL on the growth and yield of lowland rice in the SRI method, and to get the best time of gliricidia MOL application on the growth and production of lowland rice. Field research has been conducted in Tara-Tara II Village, West Tomohon Subdistrict for five months starting from June 2017 until November 2017. Treatment in the experiment consists of one treatment factor, that was interval time of gliricidia MOL application, ie  : 0, 5 , 10, 15, and 20 days. The results showed that time application of gliricidia MOL have an effect on the number of productive tillers, the number of filled grain/panicle, the number  of empty grain/panicle, and the dry grain yield (GKP) / plot, but not affect the plant height. The best results were achieved in gliricia MOL application on interval time every 15 days with a values were : 28.66 productive tillers; 176.90 fillet grain/panicle; 19.80 empty grain/panicle (lowest); and 9.50 kg dry grain yield or equivalent to 7.92 ton/ha.Keywords: gliricidia MOL, production, lowland rice,  System of Rice Intensification  (SRI)

We investigated effects of spacing and no. of seedling hill-1on growth and yield component of rice cv. Chai Nat 1 in system of rice intensification. The experiment included 25 × 25 cm, 30 × 30 cm, 40 × 40 cm, and 50 × 50 cm with single seedling hill-1, two seedlings hill-1, and three seedlings hill-1, respectively. The study was in Kasetsart University Chalermphrakiat Sakonnakhon Province Campus during November 2016 to March 2017. Each condition was laid out in a randomized completed block design with three replications. The experiment found that the no. of seedlings hill-1influence in the growth and the yield component of the rice, while the spacing does not. Moreover, there is no interaction between spacing and seedlings hill-1.The three seedling hill-1condition showed the highest in tillering (avg. = 24.13 tillers hill-1). The single seedling hill-1showed the lowest in tillering (avg. = 16.24 tillers hill-1). From this research indicated that optimized seed hill-1in rice cultivated system.

Penelitian ini dilakukan untuk menganalisa efektifitas irigasi berselang dengan neraca air pada lahan SRI dengan penerapan pupuk organik. Eksperimen dilakukan di Desa Gabus Wetan, Kab. Indramayu, Jawa Barat dari 17 November 2016 sampai 1 Maret 2017. Sensor parameter cuaca dan tanah dipasang di lahan untuk mendapatkan data harian kondisi lapang termasuk pertumbuhan tanaman. Data cuaca seperti hujan, suhu udara, kelembaban udara relatif, dan kecepatan angin dan kedalaman muka air diukur secara otomatis setiap 60 menit. Analisis neraca air dilakukan dengan kesalahan (error) yang rendah (1,00%) dimana jumlah air masuk melalui hujan dan irigasi sebesar 560 mm dan 865 mm, sedangkan jumlah air keluar melalui evapotranspirasi tanaman, perkolasi, dan limpasan berturut turut sebanyak 430, 306 dan 675 mm. Perbandingan dengan sistem pertanian konvensional dengan irigasi tergenang, menunjukkan bahwa produktivitas air dari SRI organik berturut turut 30% dan 27% lebih tinggi untuk produktivitas air berdasarkan jumlah air masuk dan evapotranspirasi. SRI organik juga memproduksi 33% produksi lebih tinggi dari sistem pertanian konvensional di lokasi yang sama. Kunci keberhasilan irigasi berselang adalah dengan menjaga tinggi muka air dipermukaan tanah (macak-macak) pada fase vegetatif dan generatif. Oleh sebab itu, cara ini merupakan alternatif pilihan bagi petani ketika sumber daya air berkurang karena perubahan iklim. Diseminasi hasil direkomendasikan melalui program pelatihan dan pendampingan bagi petani.

ABSTRACT This research aims tostudythe response of growth and yield of paddy rice to the combination of inorganic fertilizer and biological fertilizers. The design of experiments used in this study is a single factor in a completely randomized design (CRD), which consists of 5 treatments and repeated 5 times with the treatment as follows: P0 = 100% NPK (control) P1 = 100% NPK + 100% Biofertilizer Petrobio, P2 = 75% + 25% NPK Fertilizer Biological Petrobio, P3 = 50% + 50% NPK Fertilizer Biological Petrobio, P4 = 25% + 75% NPK Fertilizer Biological Petrobio. Giving Phonska inorganic fertilizer mixed with the biological fertilizer petrobio influence on the growth and yield of rice varieties Suluttan Unsrat I.

Severe water shortage in many parts of the world has caused enormous yield losses in rice. To continue feeding the increasing number of people who are dependent on rice as staple food, there is a need to address the problem on water shortage. One possible solution may be the application of alternate wet and dry (AWD) water management in rice production. This experiment was conducted to evaluate the growth and yield performance, as well as the profitability of selected lowland rice varieties under AWD water management. An experimental area of 450m2 with Umingan clay loam soil was laid out in randomized complete block design (RCBD) with three replications. Each replication was subdivided into six treatment plots with an area of 20m2 (5m x 4m) each. The treatments were: T1 – Masipag 45 (M45), T2 – Matatag 6 (M6), T3 – Masipag 129-2 (M129-2), T4 – Pinili-1, T5 -SL-8H and T6 – PSBRc-18 (check variety). Results showed that number of days from planting to heading and maturity, fresh straw yield (t ha-1), number of productive tillers per hill, number of filled grains per panicle and grain yield (t ha-1) differed significantly among treatments (p<0.05). Pinili-1 headed and matured the earliest and produced the highest fresh straw yield (t ha-1). However, M-129-2 and Matatag 6 had the highest number of productive tillers per hill, number of filled grains per panicle and total grain yield (t ha-1) which surpassed that of PSBRc18 (check variety). Masipag129-2 and Matatag 6 also gave the highest net profit of Php 23,805.00 per hectare.

Rice Intensification

Many benefits ofTrichodermainoculation for improving crop production have been documented, including growth and yield enhancement and the alleviation of biotic and abiotic stresses. However, because rice is usually cultivated under continuous flooding that creates anaerobic soil conditions, this limits the benefits of these beneficial fungi. Cultivating rice with the methods of the System of Rice Intensification (SRI) provides rice plants with a more favorable environment for their colonization by beneficial microbes in the soil because the soil is more aerobic under SRI management and contains more organic matter. This study evaluated the effects ofTrichodermainoculation of rice plants under SRI management compared with transplanted and flooded rice plants, considering also the effects of different means of fertilization and different varieties in rice. Experiments were conducted in 2015 and 2016 under the tropical climate of Nepal’s western terai (plains) during both the rainy season (July to November) and the dry season (March to July). The results indicated significantly better performance (P = 0.01) associated withTrichodermainoculation for both seasons and for both systems of crop management in terms of grain yield and other growth-contributing factors, compared to non-inoculated rice cropping. Relatively higher effects on grain yield were recorded also with organic compared to inorganic fertilization; for unimproved (heirloom) varieties compared with improved varieties; and from SRI vs. conventional flooded crop management. The yield increase withTrichodermatreatments across all trials was 31% higher than in untreated plots (4.9 vs 4.5 mt ha−1). WithTrichodermatreatment, yields compared with non-treated plots were 24% higher with organic SRI (6.38 vs 5.13 mt ha−1) and 52% higher with non-organic SRI (6.38 vs 3.53 mt ha−1). With regard to varietal differences, under SRI managementTrichodermainoculation of the improved variety Sukhadhan-3 led to 26% higher yield (6.35 vs 5.04 mt ha−1), and with the heirloom variety Tilkidhan, yield was 41% higher (6.29 vs 4.45 mt ha−1). Economic analysis indicated that expanding the organic cultivation of local landraces under SRI management should be profitable for farmers where such rice has a good market price due to its premium quality and high demand and when SRI enhances yield. These varieties’ present low yields can be significantly increased by integratingTrichodermabio-inoculation with SRI cultural methods. Other recent research has shown that such inoculation can be managed profitably by farmers themselves.
