Organic growers have indicated a need for help with the challenge of nutrient management. To address this challenge, an intensive training program for agricultural educators was convened to study this issue. Through the program, existing soil and compost analysis recommendations were modified to make them more relevant for organic growers; computer-based whole farm nutrient planning tools were evaluated using situations common to organic farms; and educational materials on using organic nutrient sources were developed for grower audiences. Educational workshops, presentations, and farm visits reached 714 growers and publications reached over 2575 people. Survey respondents of the intensive training program rated their ability to help organic growers with nutrient management as 3.50 before and 5.50 (7-point scale, with 7 = excellent) after the sessions. About 1 year later, all survey respondents rated their ability to help growers using organic nutrient sources as excellent or above average. Grower knowledge of using organic nutrient sources improved to 5.92 from 3.92 as a result of a workshop and to 5.62 from 3.89 (7-point scale, with 7 = excellent) after a 1-day class developed by intensive training participants. Methodology used allowed for expansion of individual and collective knowledge of a complicated topic and development of high impact, relevant, and effective educational programming for clientele.

A field investigation was conducted during the kharif season of 2012 at the experimental farm of School of Agricultural Sciences and Rural Development, Nagaland University, Medziphema Campus, Nagaland. Sole and combined applications of different organic nutrient sources viz., FYM, vermicompost, pig manure, rhizobium and PSB (Phosphate Solubilizing Bacteria) were evaluated in order to optimize organic nutrient management for green gram under rainfed conditions. Results showed that the combined application of rhizobium + PSB + vermicompost @ 0.7 t/ha was found to be the most responsive nutrient management practice recording significantly higher crop growth and yield attributes and ultimately recording the highest seed and stover yields of 369 and 989 kg/ha respectively. Soil available N and K status after harvest as well as seed and stover NPK uptake was found to be significantly higher with combined application of organic manures viz., vermicompost and FYM along with biofertilizers rhizobium and PSB.

Use Efficiency

Nutrient use efficiency (NUE) is an important concept in the evaluation of crop production systems. With emerging nutrient deficiencies under intensive agriculture, there is a need to improve NUE. One of the approaches to enhance it is by judicious use of fertilizers (adequate rate, effective source, methods and time of application) as well as inclusion of organic manures. Organic nutrient sources are very effective but as their availability is not sufficient to meet the nutrient demand, we have to integrate both organic and inorganic sources of nutrients together in order to achieve higher NUE. Common measures of NUE include Partial Factor Productivity (PFP), Agronomic Efficiency (AE), Apparent Recovery Efficiency (RE), Physiological Efficiency (PE) and Internal Utilization Efficiency (IE). Mineral Fertilizer Equivalent (MFE) is another parameter that can be used to assess short term release of nutrients (mainly nitrogen) from organic nutrient sources

Background: Organic production of cluster bean is to contribute to the enhancement of production sustainability along with ecology. Sustainability in organic farming must therefore be seen in a holistic sense, which includes ecological, economic and social aspects. A synergistic effectof bio fertilizer with crop increases the crop productivity and sustainability also. Bio fertilizers are low cost, effective and renewable sources of plant nutrients to supplement chemical fertilizers. Therfore to overcome the ill effect of chemical based farming, organic system is becoming the emerging need of the society.Methods: A field experiment ’’was carried out in Pusa Navbahar variety of clusterbean during summer season (February to May) of 2019 at College farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Dist. Mehsana, Gujarat, India. Sixteen treatments having various combinations of organic sources of nutrients (FYM, vermicompost, and neem cake), bio fertilizers (Rhizobium + PSB + KSM) along with RDF (20/40/0 kg/ha) as a control. They were replicated thrice in a randomized block design having a plot size of 3.0 m × 2.0 m with a spacing of 60 cm × 20 cm. Standard practices were followed during the entire course of the investigation.Result: It showed highly significant differences among different treatments for majority of the growth and yield attributing traits, but treatment T6 (75% N through FYM + Rhizobium + PSB + KSM) was rated as the best treatment for characters like days taken for germination, number of root nodules per plant, plant height at 60 DAS (cm), number of pod per cluster, number of cluster per plant, green pod yield per plant (g), green pod yield per plot (kg) and green pod yield per hectare (kg) as compared to other treatment. It can be concluded that the organic nutrient management in cluster bean with the application of 75% N through FYM + Rhizobium + PSB + KSM is beneficial for obtaining a higher yield.

Nutrient Resources

Ecological sanitation (EcoSan) systems capture and sanitize human excreta and generate organic nutrient resources that can support more sustainable nutrient management in agricultural ecosystems. An emerging EcoSan system that is implemented in Haiti and several other contexts globally couples container-based household toilets with aerobic, thermophilic composting. This closed loop sanitation system generates organic nutrient resources that can be used as part of an ecological approach to soil nutrient management and thus has the potential to contribute to Sustainable Development Goals 2 (zero hunger), 6 (clean water and sanitation for all), and 13 (climate change solutions). However, the role of organic nutrient resources derived from human excreta in food production is poorly studied. We conducted a greenhouse experiment comparing the impact of feces-derived compost on crop production, soil nutrient cycling, and nutrient losses with two amendments produced from wastewater treatment (pelletized biosolids and biofertilizer), urea, and an unfertilized control. Excreta-derived amendments increased crop yields 2.5 times more than urea, but had differing carry-over effects. After a one-time application of compost, crop production remained elevated throughout all six crop cycles. In contrast, the carry-over of crop response lasted two and four crop cycles for biosolids and biofertilizer, respectively, and was absent for urea. Soil carbon concentration in the compost amended soils increased linearly through time from 2.0 to 2.5%, an effect not seen with other treatments. Soil nitrous oxide emissions factors ranged from 0.3% (compost) to 4.6% (biosolids), while nitrogen leaching losses were lowest for biosolids and highest for urea. These results indicate that excreta-derived compost provides plant available nutrients, while improving soil health through the addition of soil organic carbon. It also improved biogeochemical functions, indicating the potential of excreta-derived compost to close nutrient loops if implemented at larger scales. If captured and safely treated through EcoSan, human feces produced in Haiti can meet up to 13, 22, and 11% of major crop needs of nitrogen, phosphorus, and potassium, respectively.

The purpose of this study was to determine the effectiveness of a computer-based training program for improving students' ability to make judgments of harmonic intonation. Twenty members of two undergraduate conducting classes participated in the Harmonic Intonation Training Program (HITP). An equivalent matched control group was selected from 156 other undergraduate music majors who had also taken the investigator-developed Harmonic Intonation Discrimination Test (HIDT). The HITP consisted of a body of drill-and-prac-tice exercises using intervals, triads, and brief three- and four-part musical passages. The exercises were played in both equal temperament and just intonation by a 16-voice digital synthesizer. After a 9-week treatment period, a two-way ANOVA on posttest HIDT scores revealed a difference (p= .005) in favor of the experimental group. Results of a questionnaire administered after the training to the experimental subjects indicated that attitudes toward the training program were mostly positive.
