Studies on the Effect of Foliar Fertilizer Application in Combination with Conventional Fertilizers on Rice Production

Abstrak - Produksi padi di Indonesia setiap tahun mengalami peningkatan, namun peningkatan ini belum mampu memenuhi kebutuhan nasional sehingga impor masih harus dilakukan. Salah satu masalah dalam produksi beras adalah penggunaan pupuk berlebih yang tidak hanya meningkatkan biaya produksi, namun juga merusak kondisi tanah. Aplikasi bakteri tanah sebagai Plant Growth Promoting Rhizobacteria (PGPR) dapat menjadi salah satu solusi terhadap masalah ini. Penelitian ini bertujuan untuk mengisolasi bakteri tanah dari 3 lokasi sawah daerah Bekasi, membandingkan keberadaan total bakteri pada ketiga lokasi tersebut, dan melakukan karakterisasi isolat berdasarkan karakter yang dapat memicu pertumbuhan tanaman. Dari ketiga lokasi, diperoleh total 59 isolat dan 5 diantaranya berpotensi sebagai PGPR karena kemampuan fiksasi Nitrogen, melarutkan Fosfat, katalase positif, dan motil. Dari ketiga lokasi pengambilan sampel, BK1 memiliki jumlah total bakteri terendah karena aplikasi pemupukan dan pestisida berlebih yang ditandai tingginya kadar P total, serta tingginya residu klorpirifos, karbofuran, dan paration. Kondisi fisik tanah BK1 juga didominasi partikel liat yang menyebabkan tanah menjadi lebih padat. Peningkatan jumlah penggunaan pupuk tidak selalu diikuti peningkatan produktivitas tanaman. Kata Kunci - Bakteri tanah, Rhizosfer sawah, PGPR, Pupuk Hayati Abstract - Rice production in Indonesia has increased annually, but this increase has not reached national demand,so imports still done. One of the problems in rice production is the use of excessive fertilizers that not only increase production costs, but also decreased the soil conditions. The application of soil bacteria as Plant Growth Promoting Rhizobacteria (PGPR) can be the one solution to face this problem. The objective of this study was isolate soil bacteria from 3 locations of rice field in Bekasi, compare the total bacteria in the three locations, and characterize isolates based on the character that can promote plant growth. From three locations, a total of 59 isolates were obtained and 5 of them were potential as a PGPRs due to its Nitrogen fixation activity, Phosphate solubilization, positive catalase, and motility. From three sampling sites, BK1 has the lowest TPC value because of excessive fertilizers and pesticides application which indicated by high total P levels, and also high chlorpyrifos, carbofuran and paration residues. The physical condition of BK1 soil is also dominated by clay particles which causes the soil more solid. Increasing of fertilizer application is not always followed by increased plant productivity.

Opportunity to Increase Rice Production in Fresh Water Swampy Land in LampungThe area of fresh water swampy land in Lampung in 2012 was 55,714 ha with rice productivity of 5.13 t/ha so it is possible to be increased. The article discusses opportunity to increase rice production in fresh water swampy land in Lampung. Increasing rice yield can be done by enhancing cropping index and land productivity, lowering yield gap and decreasing yeld loss. Cropping index in fresh water swampy land can be increased by cultivating rice with surjan system, while rice yield is increased by integrated crop management (ICM) which its components include the use of improved varieties, planting with legowo 2: 1 or 4: 1, fertilizer application according to plant need, water management to prevent rice plant from submerging or drought, and integrated pest management. Rice yield gap is decreased by implementing location specific technologies and intensifying counseling to farmers, while yield loss is lowered by applying integrated pest management and using agricultural tools and machineries in rice farming. These production increases have an impact on the regional and national food availability in an effort to achieve rice self-sufficiency.Keywords: Rice, production, fresh water swampy land, growth source ABSTRAKLuas lahan rawa lebak di Provinsi Lampung pada tahun 2012 mencapai 55.714 ha dengan tingkat produktivitas padi 5,13 t/ha sehingga masih berpeluang ditingkatkan.

Hydroponically Grown

Nutrient application is one of the major inputs required for hydroponic production of cucumbers. Reduced nutrient solution concentration with supplementary foliar fertilizer application may maintain yield and quality of mini-cucumber, while decreasing the production costs. An experiment was conducted to determine the effect of foliar fertilizer in combination with reduced nutrient concentrations on the yield and quality of hydroponically grown mini-cucumber in a plastic tunnel. Mini-cucumber plants were grown in sawdust, fertigated with nutrient solutions containing 100% (control), 75%, 50%, or 25% of the recommended nutrient concentration (NC) and two foliar fertilizer applications (no foliar and foliar application). The highest fresh and dry weight of mini-cucumber plants were obtained with 75% and 100% NC and decreased with 50% to 25% NC application. The number of marketable fruit and marketable yield on mini-cucumbers increased with 75% to 100% NC, followed by 50% NC, as compared with 25% NC. Deformed fruit were significantly lower at 25% NC than at 50%, 75%, and 100% NC. Foliar fertilizer application did not have an effect on mini-cucumber yield, but reduced the yellowing of fruit. Fruit mineral content (P, Fe, and Mn) was significantly improved by 100% NC. Improvement in yield at 75% and 100% NC was as a result of improved plant height, leaf chlorophyll content, plant fresh and dry weight, and the increase in nutrient uptake of N, P, K, and Mn, which was evident in the analysis of cucumber leaves. The reduced NC of 75% can maintain yield and quality of mini-cucumbers, whereas the application of foliar fertilizer had a limited effect.

Soil Fertilizer

Yield and quality of chestnut (Castanea mollissima) are affected by nitrogen availability; however, there are few reports on foliar and root absorption of different chemical forms of N in chestnut. To analyze the absorption characteristics of exogenous nitrogen fertilizer labeled by 15N in chestnut, nitrate and ammonium nitrogen uptake and allocation were determined in one-year-old seedlings that received soil- and foliar 15NH4NO3 and NH415NO3. We found that 29% of the nitrate and 25% of the ammonium absorbed by the leaves were translocated to the roots, while 62.01% of the nitrate and 63.27% of the ammonium absorbed by the roots were translocated to the shoots. The seedlings absorbed more nitrate nitrogen than ammonium nitrogen and their foliar N uptake was faster than their root uptake. Most of the N absorbed by the seedlings was fixed in the shoots in both foliar and soil uptake. The proportion of N fixed was greater in seedlings subjected to foliar fertilization than in those treated with soil fertilizer. Foliar fertilizer application can meet the N nutritional needs of fast-growing shoots more effectively than soil fertilizer application. However, soil fertilization was a better long-term N source than foliar fertilization. Thus, ensuring an adequate supply of nitrate N fertilizer in the soil accompanied by a commensurate increase in foliar fertilizer application can effectively meet the nutrient requirements associated with the rapid growth of chestnut seedling shoots.

Effect of prunning technique and foliar fertilizer application had been conducted to improve yield of pecco in the Research Institute for Tea and Cinchona experiment station, Gambung, Indonesia with altitude of 1.350 m above sea level, and with andysol soil type. The experiment was held from July to October 2015 in tea production field area containing 480 plants. The clone was GMB 7and was in the fourth prunning year, interval of plucking pecco was seven days. The experiment was arranged in a randomized block design with four treatments, replicated six times. Foliar fertilizer application was performed following every plucking. The results indicated that breaking apical dominance of tea short by 5 cm–10 cm of prunning above plucking table combined with foliar fertilizer application of N 1% and ZnSo4 2% + 0,1% of humic acid, could increase weight of pecco per plot in the first nine weeks of the prunning. This treatment was better than the other three. But the percentage of pecco shoots was low, lower than 50%, the weight of one pecco was also very low 0,7 g, indicating that the treatment of harvesting pecco in the fourth prunning year was not recomended to be practiced in improving yield of pecco.

This study was conducted to evaluate the effect of different types of fertilizer application on the growth and flowering of 'Puyat' Durian (Durio Zibethenus Murr.); and determine the best fertilizer application for the optimum production of Durian. Ten (10) year old trees at Canoy Durian Farm, Pindasan, Mabini, Compostela Valley Province were tested from November 2015 to March 2016. The experiment was laid out in Randomized Completely Block Design (RCBD) with six treatments, replicated three times. The treatments were: T1- Untreated; T2-Recommended Rate- RR (based on soil analysis); T3- Optimum RateOR + (3kg NPK+1kg MOP); T4- OR+ GOFF; T5- RR+ GOFF; T6- GOFF (Green-shield Organic-based Fortified Foliar Fertilizer).Statistical analysis showed that there were significant differences among treatments in terms of trees with flushes and number of flowers per cluster but no significant effects were observed in canopy diameter and number of flower cluster per tree. Result of the study showed that fertilizer application increased the number of flower per cluster of 'Puyat' Durian and enhanced flushing of durian trees. The study further revealed that organic based foliar fertilizer alone enhanced flowering up to five times higher than without application (control). While numerically, GOFF (Green-shield Organic-based Fortified Foliar Fertilizer) alone had the highest number of flower cluster per tree.
