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. Treatment NPK fertilizer Phonska 75% and 25% of biological fertilizers petrobio produce an average plant height is 98.40 cm high, 24.40 cm panicle length , Total grain permalai 167 grains, grain pithy permalai Total 155.20 grains and weight of 1000 grains contain.Key words: rice paddy fields, of SRI (System of Rice Intensification), inorganic fertilizers, biofertilizers

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.

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)

Field experiment was conducted in coastal alluvium soil of eastern India during late rabi of 2009-10 and 2010-11 in split split-plot design with three dates of sowing for rice-ratoon i.e. 20 June, 5 and 20 July followed by green gram cv. PDM-139 (Samrat) i.e. 2 January, 17 January and 1 February in main plots, three systems of cultivation of the preceding rice-ratoon i.e. ratoons of rice under best management practices (BMP), system of rice intensification (SRI) and modified SRI (MSRI) in sub plots and two genotypes of rice-ratoon i.e. HR Ajay and HYV Tapaswini in sub sub-plots. Green gram was grown under residual soil nutrient and the crop sown on 2 January recorded the highest seed yield of 0.703 t ha-1 (REY of 2.933 t ha-1) and this was followed by sowing on 17 January and 1 February. The seed yield of green gram followed diminishing trend under SRI-ratoon, MSRI-ratoon and BMP-ratoon, respectively.
