Abstract: The present study
was conducted to evaluate the effect of growing media, hormonal treatments
and growing seasons on the shoot and root characters and survival percentage
of cuttings of lemon cv. Pant Lemon-1.Pooled data of two season (rainy and
spring) has shown that soil+sand+FYM growing medium
resulted maximum length of sprouts and average number of leaves per cutting.
Whereas, average diameter of shoot and average length of longest roots were
maximum in soil+cocopeat based medium. Average
diameter of root was higher in soil+cocopeat and soil+FYM medium, but did not differ significantly.
Maximum survival percentage of cuttings was noted with soil+sand+FYM.
IBA (500 ppm) was found superior regarding for all
parameters except on average diameter or roots per cutting with IBA+NAA (500 ppm each). Taken as a whole, rainy season was found
superior over spring season in respect to all shoot and root characteristics. Key words: Cuttings, Growing

Abstract: Coriander (Coriandrum sativum
L.) is an annual spice herb that belongs to the family Umbelliferae.
Even though Ethiopia is a centre of primary diversity for the crop, the
current knowledge about its biology, variety development and agronomy is
neither complete nor conclusive under ethiopian
conditions. To contribute to filling some of the existing gaps, a field
experiment was conducted during the year of 2011-12 a seventy one accessions
of coriander were screened for resistance against stem gall, a sever
disease caused by Protomyces macrosporus Unger., with the
goal to select the resistant cultivars. The accessions DCC-37 (Devihosuru coriander collection), DCC-49 and DCC-51,
DCC-10, DCC-32 and Sudha were highly resistant.
These may be used as the parents to breed high yielding accessions resistant

Abstract: This study an
attempt was made to assess the organoleptic
acceptability and nutritive value of value added food products prepared from
the incorporation of less utilized dehydrated lahsua
leaves which are usually discarded or are used as animal fodder. The lahsua(Digera arvensis)
leaves powder was done through tray drying at 60- 650C for 15
hours. The products prepared were biscuit and namakpare
by incorporation of dehydrated lahsua leaves powder
at 15, 20, 25% and served as treatments T1,
T2 and T3 respectively. T0
without incorporation of dehydrated lahsua leaves
powder served as control. Organoleptic evaluation
was carried out using the nine point hedonic scale and nutritional
composition was calculated using the food composition table given by ICMR. On
the basis of findings, it was observed that namakpare
and biscuit T1 (15 percent) was found to be best with regards to flavour and taste and overall acceptability. It was also
observed that calcium, iron, protein and total carotene content in prepared
products increased significantly as the incorporation levels increased. Thus
dehydrated Lahsua leaves powder can be incorporated
in the preparation of different food products to improve their nutrient

Abstract: Radish (Raphanus sativus) is one of the
major vegetable crop grown throughout the country.
It is widely grown in different parts of the country mainly by small and
marginal farmers. The planting operation of the radish crop is not mechanized
in India, with most of the area cultivated by line sowing and broadcasting
operation. However, problem of flow of material are experienced. Pelletizing
of the radish seed by providing a seed coat, helps
in changing the physical characteristics of the seed. The biometric
properties of seeds play an important role in designing seed metering device.
Physical and engineering properties of radish seed both un-pelleted and pelleted (T0,
T1, T2 and T3) were evaluated in the
laboratory. The average major and intermittent dimension of T0, T1,
T2 and T3 seed were 3.31 mm, 3.75 mm, 4.27 mm, 4.35 mm
and 2.72 mm, 3.11 mm, 3.64 mm, 3.84 mm, respectively.T3
enhanced the major and intermittent dimension of seeds. Roundness value and sphericity of T0, T1, T2
and T3 seed were 0.70, 0.79. 0.82, 0.90 and 0.78, 0.84, 0.85, 0.91
respectively. The geometric mean diameter was maximum for T3
radish seed (3.94 mm) followed by T2 (3.65 mm), T1
(3.14 mm) and T0 (2.58 mm) radish seed. Thousand seed weight, W
1,000 of T0, T1, T2 and T3 was
11.74 g, 23.43 g, 32.86 g and 46.05 g respectively. Angle of repose and

(31.41 & 26.87) and plant height (28.12 & 19.19). High heritability
coupled with high genetic advance as percentage of mean (GAM) was recorded
for seed cotton yield (59.86 & 41.39), boll number (25.62 & 33.93),
lint yield (57.71 & 49.79) and number of sympods
(51.75 & 41.15) at Faridkot and Ludhiana
respectively. Hence simple selection based on phenotypic performance of these
characters would be more effective. Key words: Gossypium arboreum, Genetic variability, Heritability,

Abstract: A long term field
experiment on the transformations of phosphorus under different nutrient
management practices and cropping systems in Vertisol
(Typic Haplustert) of
Northern Transition Zone of Karnataka was initiated in 2004-05 at the
Institute of Organic Farming, Main Agricultural Research Station Farm, UAS, Dharwad. Application of organic
manure continuously for eight years decreased all the fractions of
phosphorus. Hundred percent inorganic nutrient management practice recorded
statistically higher phosphorus fractions in the order Ca-P (45.5 mg/kg) >
Al-P (35.9 mg/kg) > Fe-P (22.3 mg/kg) > occluded-P (14.6 mg/kg) > saloid-P (11.4 mg/kg) at both the depths (0-30 cm and
30-60 cm) while available-P (23.8 kg/ha) was statistically lower in this
system when compared to other nutrient management practices. All the
fractions of phosphorus (saloid-P, Al-P, Fe-P,
Occluded-P and Ca-P) were highly inter-related and significantly correlated
with each other and negatively correlated with available phosphorus content. Key words: Phosphorus

Abstract: Experiments were
conducted to develop and evaluate the quality of jaggery based papaya leather
.The citric acid levels of 0.5%, 0.75% and 1.0% were used for the preparation
of papaya leather. After preparation of papaya leather, the finished products
were packed in PET and glass jars. The study revealed that the moisture
content increased while TSS and Vitamin-C decreased with increasing the level
of citric acid from 0.5 to 1.0%. During storage there was a reduction in
moisture content, pH and vitamin-C, where as TSS (total soluble solids) and
optical density increased during storage. The organoleptic
score of the leather samples in glass jars at 0.75% citric acid level was
found to be higher followed by samples packed in PET jars. Key words: acidity, leather,

Abstract: The present
investigation was undertaken in Sorghum (Sorghum bicolor (L.) Moench) at Sorghum Research Station, Vasantrao
Naik Marathwada Krishi Vidyapeeth, Parbhani (Maharashtra) during kharif2008-09.Eight
hybrids along with six parents and four checks (PVK 400, PVK 801, GMRP 9, and
CSH 16) were evaluated in randomized block design with three replications. In
general, higher heterotic effects were observed in
the crosses involving PMS 28A and 6938B as the female parent and KR 192 and C
43 as the male parents. A total of 7, 8, 3, 8 and 7 hybrids exhibited
positive and significant heterosis for grain yield
over better parent and standard check viz., PVK 400, PVK 801, GMRP 9
and CSH 16, respectively. High and significant heterosis
was observed in the crosses 6938A x C 43, MS 28A x C43 and PMS 28A x KR 192
for grain yield as well as earhead length, earhead girth, earhead weight,
test weight, grain hardness and germination percentage. The crosses PMS 28A x
C 43 and PMS 28A x KR 192 showed significantly desirable heterosis
for all the four grain mold attributes viz., field grade score, grain
hardness and germination percentage Key

Abstract: The present
investigation was carried outduring the year
2006-07 and 2007-08 with main objective to find out the morpho-physiological
differences between “4 regular bearing and 5 biennial bearing varieties. The
experiment was layout in Randomized Block Design with three
replication. The experimental material consist of 9 cultivars of mango
viz., Mallika, Amrapali, Totapuri, Neelum, Dashehari, Chausa, Bombay Green
and Safeda. The maximum extended shoots were
observed in regular bearing variety during ‘on’ year while it was observed
maximum during ‘off’ year in biennial bearing variety and during ‘off’ year
in regular bearing variety. Length and diameter of extended and unextended shoots were observed maximum in biennial
bearing variety during both on and ‘off’ years. Thus, it can be said, that
alternate bearing problems of mango varieties can be minimize by applying the
morphological and Phenological measures viz. debloosming cultural practices. Key
