Organic And Inorganic Fertilizers

Rice is the most important staple cereals in human nutrition and consumed by 75% of the global population. Rice plant needs supply of essential nutrients for its optimal growth. Rice production has been increased tremendously in India after green revolution combined with insensitive irrigation and use of inorganic fertilizers and pesticides. However, the effect of using inorganic fertilizers has resulted in contamination of ground water and decreased the productivity of soil, which in turn affects the rice production in long term. Use of organic manure may help to regain the soil health but they are insufficient to provide the essential nutrients to achieve optimal growth. So, use of organic manures combine with inorganic fertilizers are followed to obtain optimum yields. This study aimed to test the effect of the different organic fertilizer and combinations of organic and inorganic fertilizers on the qualitative and quantitative parameters of two cultivars of rice as DRR Dhan 39 and RP.BIO.226. The experiment was conducted on the farm located at Fasalwadi village, Sangareddy district, Telangana during kharif season in randomized complete block design with three replications. The treatment included two controls and 10 combinations of four organic fertilizers as farmyard manure, vermicompost, Panchagavya, Jeevamrutha and inorganic fertilizers as combination of 60:75:75 levels of N, P and K. Grain and straw samples were collected and physical parameters were measured at harvest stage. The results indicated that the variety DRR Dhan 39 gave the statistically significant (P<0.0001) higher grain yield of 8713 kg/ha and straw yield of 9483kg/ha with 50% organic fertilizers of Vermicompost, Jeevamrutha 5% and Panchagavya 3% and 50% inorganic fertilizer of NPK. On the other hand, the variety of RP.BIO.226 gave the highest grain yield of 6390 kg/ha with Vermicompost, Jeevamrutha 5% and Panchagvya 3% (8 t/ha, foliar spray and 500 litres/ha) and highest straw yield of 7430 kg/ha with T10 treatment (50% organic fertilizers of Vermicompost, Jeevamrutha 5% and Panchagavya 3% and 50% inorganic fertilizer of NPK). Both varieties of rice poorly responded to inorganic fertilizers with lower grain and straw yield. Statistically significant differences were observed in both varieties of grain crude protein (CP%), straw acid detergent fiber (ADF%), crude fiber (CF%) and acid detergent lignin (ADL%) with different fertilizers

AbstractRice is the most important agricultural commodity of the Lao People's Democratic Republic (Lao PDR), produced largely using traditional methods with limited inputs of fertilizers and other chemicals. The country has a wide diversity in rice production systems and rice varieties, with over 3000 different varieties recorded. The rich diversity and the production environment and methods are favorable for organic rice production. Investigations were carried out to describe soil fertility conditions, management practices, opportunities and problems associated with organic production methods for rice. Soils used for rice production are mostly of low fertility, with low organic matter and N-availability. In spite of this, virtually no fertilizer inputs are used for upland rice production. Inorganic fertilizer inputs for lowland rice production have increased rapidly over the past decade, but are still below 20 kg ha−1. The most important nutrient sources are rice straw and manure from buffalo and cattle. Chromolaena odorata plays an important role in nutrient cycling in upland rice systems and is sometimes added to lowland fields. In a range of fertility management studies, yield increase ranged from 2 to 89% for manure, straw or rice husk applied at modest rates (3 t ha−1), 32–156% for modest rates of inorganic fertilizer (60 kg N ha−1) and 36–167% for combined application of manure or crop residues with inorganic fertilizer. The response to locally produced commercial organic fertilizer was poor. The most promising inputs and strategies available to optimize yields in organic rice production systems are (1) optimizing use of locally available nutrients, mostly from manure, crop residues and weed biomass, (2) N addition through green manure and legumes growing in rotation and (3) additions of P through guano or rock-phosphate. The Lao PDR is fortunate to have substantial bat guano deposits in limestone caves. Extensive experience is available on straw and husk management for lowland systems and green manure species for upland production systems.

The area of agricultural land, especially paddy fields, is related to the level of rice production. Conversion of agricultural land to non-agriculture will have an impact on the availability of rice supply. This study aims to identify changes in paddy field land use in 2005 - 2016 using high-resolution satellite imagery and calculate the need for rice per capita in Pallangga District. This research utilizes the application of geographic information systems in monitoring changes in paddy field use. The method used in the classification of land use is digitizing on screen. The conversion of paddy fields to non-paddy fields was obtained from the results of overlapping maps of Pallangga District land use maps in 2005 and 2016 and presented in the form of cross tabulations. The accuracy test results obtained the overall accuracy value of 98.04%, and the kappa accuracy value of 0.98. This study shows that paddy field area has decreased by 305.25 ha. The change consisted of 17.68 ha into a water body, turned into a garden of 132.86 ha and became a settlement of 154.71 ha. The conversion of paddy fields in Pallangga District in 2005-2016 affected rice production. The results of the analysis of the needs of rice per capita per year show that in 2017 Pallangga District is surplus in the supply of rice to its population. However, based on population projection, the decrease in land area and rice production in Pallangga Subdistrict in 2020 was unable to meet the rice needs of its population of 1,027 tons

The focus of this study was to observe the behavior of the Marind Tribe in cultivating paddy field. The study intended to develop lowland rice by paying attention to the behavior of the Marind Tribe as agribusiness actors. This study aims to analyze the knowledge, attitudes, forms of action of Marind tribe farmers in rice farming and analyze the rice production produced. This research was conducted in Merauke Regency as a center for rice production in the province of Papua. The method used in this study is a survey method with in-depth interview techniques and observations of 120 Marind farmers who work on lowland rice in six districts in Merauke Regency. Data were analyzed using descriptive statistical analysis and inferential statistics.  The results of the study concluded: (1) the knowledge of the Marind Tribe is still in the basic realm of knowing; (2) the Marind Tribe is hesitant to apply the cultivation of lowland rice; (3) the form of actions for planting lowland rice is incomplete; and (4) the level of production of lowland rice produced is very low.
