Title : Effect of Different Maturity Stages and Surface Treatments on Shelf life of Mango cv. Maldah Material Type: printed text Authors: Neelam Subba, Author ; Keshab Gliimire, Author ; B.L. Yadav, Author Pagination: 71-74 p. Languages : English (eng) Keywords: Maturity stages, surface treatments, TSS, TTA Abstract: The effect of maturity stages and surface treatment on shelf life of mango cv. Maldah
was studied in room temperature (27-31°C and 67-84% RH) at farmers' storage
condition in Mulghat (370masl). The shelf life of mango harv_ested at three different
stages; mature green, half ripe and full ripe was subjected to three different surface
treatments; hot water dip (53:t.2°C for 5 min), 2% CaCI2 for 10 minutes, individual
polythene wrap and control. Through out the storage time, the changes in fruit weight,
number of fruits decay, total soluble solids (TSS), total titratable acidity (TTA} were
measured. The interaction effect of maturity stages and surface treatment was found
significant on shelf life of fruit. The study revealed that mango could be stored for 7-10
days at room temperature with surface treatments; hot water treatment and surface
treatment of fruits with CaCI2 solution were found effective in all three stages for
controlling post haNest losses due to anthracnose. Fruit loss due to disease was 21,
29.3 and 34.06% higher in three stages of maturity respectively in control in
comparison to hot water treated fruits. Weight loss due to shrinkage was found lowest
(1.67, 2.83 & 7.53-14.50 gm) in fruits individually wrapped in polythene in three stages
respectively. Other quality parameters such as changes in TSS and TT A did not differ
significantly among surface treatments.Link for e-copy: http://elibrary.narc.gov.np/?r=207 Effect of Different Maturity Stages and Surface Treatments on Shelf life of Mango cv. Maldah [printed text] / Neelam Subba, Author ; Keshab Gliimire, Author ; B.L. Yadav, Author . - [s.d.] . - 71-74 p.

Title : Enhancing Maize Productivity Through the Use of Split Application of Nitrogen and Irrigation at Critical Stages in Sandy Soils of Rampur, Chitwan. Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Krishna B. Karki, Author Publication Date: 2008 General note: In: IAAS Plant Breeding Journal, 2008, vol 3:37-42. Languages : English (eng) Keywords: Basal and split application, critical stages, irrigation, topdressing, nitrogen use efficiency zea mays. Abstract: Split application of Fertilizer-N and subsequent irrigation on maize field at critical stages could help increase urea-N use efficiency in sandy soils of Chitwan and thus crop productivity increased. To evaluate the effects of split application of urea-N and irrigation at critical stages of crop growth, an experiment was conducted in the acidic sandy soils of NMRP farmland during the year 2005. Ten t/ha of compost and 60 :40 kg P2O5 and K2O, respectively, were applied basally in all the experimental plots. Some plots received only 50 ky Fertilizer-N and in some 100 kg/ha, which were applied either basally or splitted 2 or 3 times and crop was irrigated 1 or 2 times at the critical stages of crop growth and some crops were not irrigated. Crop was planted at the plot size of 12 sq.m in February and harvested in June. Variety used in the experiment was Arun-4. Crop growth and yield parameters were taken into study and analysed statistically. The crop growth parameters such as plant height, stem girth, straw yield,leaf numbers and number of nodes per plant were observed to be significantly affected by the treatments. Similarly, their effects on test weight (100 grains wt.) and grain yield were also found significantly affected. The highest test wt (341.33 g) was recorded when the crop was supplied with 100 kg N which was applied half as basal and half as topdressing at knee-high stage, followed by 2 irrigations, one at topdressing time and anotherin tasseling stage.Maximum grain yield(4.04 t/ha) was recorded at this level of N application and frequencies of irrigation which produced approximately 134 % higher grain yields as compared to that of non-treated crop followed by 3 split application of fertilizer-N (half basal, ¼ at knee high stage and ¼ at tasseling stage) provided with 2 irrigation, one at 1st topdressing and 2nd in 2nd topdressing time (3.86t/ha0. It is concluded that 3 split application of fertilizer-N with 2 subsequent irrigation at critical stages could help increase the urea-N efficiency and increase the crop productivity of winter maize in sandy soil condition of Chitwan.

Title : Yield Loss and Economic Threshold Level of Soybean due to Leaf Roller (Apoderus Cyaneus Hope) in Nepal Material Type: printed text Authors: Gyawali, Bishnu K., Author Publication Date: 2005 Article on page: 73-77 p Languages : English (eng) Keywords: Economic threshold level, leaf roller, physiological growth stages, yield loss Abstract: Yield loss in soybean due to leaf roller (Apoderus cyaneus Hope) was studied at Khumaltar during
1985 and 1986 seasons. Field experiments were conducted during vegetative as well as reproductive
stages of soybean. Rolled leaves of soybean with eggs, grubs and pupae were collected from the
field and reared in the laboratory for adults. Adults were introduced into nylon cages installed at
the central rows of each plot just after germination of soybean. Insects were maintained at
population density of 25, 50 and 100 per m2. At maximum (100) adult density, the potential grain
yield loss of cultivar, Ransom soybean in its vegetative and reproductive stages were 103 and 48 mg
per day respectively from each adult of A. cyaneus. Percentages of yield losses were 36.2, 45.2,
and 58.0 during vegetative and 37.5, 48.5 and 66.0 during reproductive stages from the insect
population of 25, 50 and 100, respectively which, was
not in accordance with the level of two and four fold increased population density of insect. Yield
reduction was higher (260 and 108 mg per day) from each adult beetle at lower population level (25)
in both vegetative and reproductive stages of soybean.Link for e-copy: http://elibrary.narc.gov.np/?r=64
