Different sources of phosphorus

Fertilizers are one of the costly inputs but continue to exert significant contribution to produce additional food grains. To realize maximum benefits and reduce nutrient losses from fertilizers, they must be applied in the right quantity, source and combination at the right time using the right method.

To eradicate the malnutrition problem and improve the protein deficient diet and low yield of pea, it is necessary to increase pea production per unit area on sustainable basis to meet the requirement of increasing population of the nation. In view of that, experiment was executed to examine the response of four different organic manures viz. farmyard manure, vermicompost, castor cake and poultry manure as a source of nitrogen with or without chemical fertilizers like phosphorus and potassium and biofertilizer i.e. PSB were tested during the year of 2012 and 2013.

The major uses of soybean are as a source of edible oil and protein rich food, as well as cattle feed. The nutrient requirement and interaction of different nutrients under high phosphorus conditions were not worked out so far in soybean track. To improve the productivity levels of soybean it is imperative to assess the nitrogen and phosphorus requirement under high P fertility soils to obtain the potential yield by the farmers.

Field experiment was conducted during rabi-2018 at Research Institute of Organic Farming field unit, UAS, GKVK, Bengaluru to study the different sources of organic phosphorus and PSB on growth, seed yield and essential oil content in coriander laid out in Randomized Complete Block Design with 10 treatments replicated thrice and the variety used was Co Cr-4. Results of the experiment revealed that phosphorus at 40 kg ha-1 applied through neem cake + PSB at 2 kg ha-1 recorded significantly higher seed yield (665 kg ha-1 ) and essential oil yield (4.72 kg ha-1 ).

A field experiment was carried out during kharif, 2018 at the research farm of the ICAR, Indian Institute of Rice Research (IIRR), Hyderabad, Telangana state. The soil of the experimental field was clay loam in texture, low in available nitrogen, medium in phosphorus and high in potassium content. The experiment was laid out in randomized block design with eleven treatments and each one replicated thrice. Highest net returns Rs 92,658 ha-1 was recorded with the application of 100% RDN through neem coated urea.

The present study was conducted on 12 dogs of either, sex, breed, aged between 1-8 years brought to T.V.C.C, Jabalpur having a diaphyseal fracture in any of the long bones i.e. Humerus, femur and tibia. The dogs were randomly divided into three equal groups irrespective of breed and sex. The radiographs in two standard views were taken to diagnose the fracture and to select optimum titanium pins. In all the three groups, the diaphyseal fractures were repaired with internal fixation using titanium elastic pin. In group I, the fracture was repaired by using the titanium pin alone.

Grapes are good source of dietary sugars, organic acids and provide good amount of minerals like iron and phosphorus and some vitamins. Among the grape processed products raisins are one of the most important processed products obtained from grapes. The mature, clean and uniform size green grape berries (Thompson seedless) were taken. The berries were treated by using different methods viz. Preyal dip, Australian dip and soda dip. Drying was done at 50 and 60oC to study the effect of drying temperature on quality of raisin. The grape berries were dried from 78 per cent (345.54 per cent, d.

Nitrogenous fertilizers applied to soil undergo various physico-chemical and biological transformations due to influence of different enzymes and microbial activity and thereby become available to crops. The efficient use of nitrogen is recognized as an important production factor for rice production but it has always been a problem to raise its utilization rate by rice and to increase efficiency of absorbed nitrogen for grain production. Even with the best agronomic practices only 30-40 percent of applied nitrogen is actually utilized by the crop.

To reduce the likelihood that variability, in appraisal scor- ing between researchers, did not exclude valid material for synthesis, 42% (43/103) of all reports categorized as ‘Mid’ were re-appraised for inter-rater reliability. A purposive approach was used to capture potential sources of variabil- ity. Therefore, selection of excluded reports for re-appraisal ensured that different types of interventions (i.e. popula- tion-based, experimental, school-based, etc.
