Nitrogen Dynamics in Organically Cultivated Paddy Soils of Coastal Cauvery Deltaic Region
A field experiment was conducted at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal during Rabi 2018 to study the nitrogen dynamics in organically cultivated paddy soils of coastal cauvery deltaic region. This study was conducted to evaluate the extent of nitrogen contribution and their dynamics in soil by added organics like green manures (Daincha and sun hemp) and green leaf manures (Pungam and gliricidia) with different levels of vermicompost Viz., 0 t ha-1, 1 t ha-1 and 2 t ha-1. The mineralization pattern of nitrogen is NH4 - N and NO3 - N. During decomposition, before transplanting, after transplanting in early and later stages noted a gradual increase in nitrogen release but steady release observed during mid-stages. In terms of losses, the control registered significantly higher volatilization loss of 1.99 Kg N ha-1 week-1 during second week after transplanting. While the organic treatments registered significantly higher volatilization loss during 13th and 14th week after transplanting. Similarly, the control plot registered significantly higher loss of NO3 - N (2.25 Kg ha-1 week-1) during the 1st week after transplanting and the organic manures showed higher NO3- N loss during 5th to 9th week after transplanting. The total weed removal of nitrogen ranging from 1.8 to 2.6 kg N ha-1. In total, the losses of N from rice soil including crop uptake ranged from 94.6 kg ha-1 in absolute control to 147.2 kg ha-1 in daincha treated plot. As well as, the daincha treated plot resulted a net gain of + 9.6 kg N ha-1 among other green manure / green leaf manure treatments. Among the different vermicompost treatments, application of vermicompost at 2 t ha-1 resulted a net gain of + 4.4 kg N ha-1. From the above observations, it could be concluded that, application of daincha is found to be a suitable green manure for rice crop. Which helps to synchronize and release the nitrogen as per the demand of rice crop.
Anaerobic digestion of biomass for energy generation
The continuous depletion of fossil fuel reserves, consequent escalation in fuel prices and growing environmental concerns have triggered a renewed interest in exploration of alternate substrates as a source of energy. The use of renewable energy sources is gaining importance as alternative sources of energy, to reduce emission of greenhouse gases from fossil fuel sources that have impact on global warming. In the context of providing a devolved and sustainable energy supply the potential of anaerobic digestion of biomass is of particular interest. The product of anaerobic digestion of biomass is biogas which is a type of biofuel. Biogas is produced by fermentation of biodegradable materials by microbial consortia employing anaerobic digesters. These digesters can be fed with biomass and during the digestion process, biodegradable wastes are transformed into renewable energy in the form of methane, that can be used for heating, lightening, electricity generation and many other operations.
Impact assessment of drip irrigation on field crops in India: A Review
Water is the foremost natural resource, which is continually expensive and limiting input particularly in arid and semi arid regions, hence needs judicious use to harvest the maximum benefit from this limiting resource. Indian farmers are now finding ways to move from traditional practices to ultramodern technologies for crop production. Lately, drip irrigation is getting positive reception, acceptance, and adoption and plays a significant role in saving the water in water scarce areas. It enables the efficient utilization of limited water with improved water use efficiency. Adaptation of drip irrigation in major field crops of India like wheat, maize, sugarcane, legumes, oilseeds, seed spices is gaining momentum because of its higher productivity. By introducing drip irrigation, it is possible to increase the yield potential of crops by three times with the same amount of water. Enough experimental evidence is available from various parts of the country to suggest that drip technology saves water in comparison to surface method of irrigation from 18.7 to 47.7% in orchards and fruits, 2.1 to 42.9% in field crops, 11.9 to 38% in vegetable crops, 14.3 to 51.3% in root, bulb and tuber crops, 12 to 56% in plantation crops, 36.7 to 46.7% in spice crops and 41.4 % in flowers in a appropriately designed and managed drip irrigation system. Therefore, optimum irrigation levels with drip system would help in enhancing the economic yield as well as water use efficiency of field crops.
Studies on inducting variability in sweet potato [Ipomoea batatas (L.) Lam.] cv. ST-14 through gamma irradiation
This study was undertaken to evaluate the effect of gamma irradiation on morphological, yield and biochemical attributes of sweet potato [Ipomoea batatas (L.) Lam.] cv. ST-14. Cuttings of sweet potato vine were irradiated with gamma rays (15, 30, 45, 60, 75, and 90 Gy) and non-irradiated cuttings were chosen as controls. After irradiation, cuttings were planted in replication in a well-prepared field at 30 x 30 cm spacing. Result revealed that average days to 50 (%) sprouting was significantly delayed with increasing doses of gamma irradiation. Among the gamma irradiation earliest day of 50 (%) sprouting was recorded in 15 Gy (12.49 days), whereas the delayed sprouting was recorded at 45 Gy. The maximum sprouting per cent, survival per cent and vine length was recorded in control followed by 15 Gy. Exposed to higher dose of gamma irradiation tends to decease in sprouting per cent, survival per cent and vine length of sweet potato. The LD50 value occurred at 45 Gy gamma irradiation level. The results indicated that gamma irradiation treatment was adversely affected vegetative parameters, such as vine length, number of leaves, leaf length, leaf width, and average fresh weight above ground level were recorded in irradiated plants over the control. TSS, starch content, sugar percentage, and carotenoids content were unaffected by irradiation treatment and were found to be non-significant in both generations. In conclusion, our findings indicated that gamma irradiation had a significant impact on vegetative and yield characteristics but had no effect on biochemical properties.
Status And Need Of Mechanization Of Oil Palm Harvesting In Telangana
Oil palm is a tree without branches but with many wide leaves at its top. It has become the world’s number one plantation crop because of its unparalleled productivity. One of the important and cumbersome activities in palm fruit cultivation is harvesting. Harvesting of oil palm is difficult due to its thorns like cut stems. Harvesting is being carried out manually by using sickle and pole arrangement. But the process is cumbersome and needs lot of effort. To reduce the difficulty of harvesting and to achieve good productivity of the crop an optimum machine has to be developed. Much research was done in this sector, but still the industry is in the need of an optimum machine. Hydraulic lifting platforms, motorized (cantas) cutters, pneumatically operated cutters, were developed but these have their own setbacks. Recently, focus was drawn towards the robotics. Here, this paper explains all the available and developing technologies in the area of harvesting of oil palm.
