Seven exotic varieties and two commercially grown cultivars of pear grafted on quince were evaluated for various physio-chemical characteristics for two years in the orchard of Department of Horticulture, Srinagar, Jammu and Kashmir. Among various physical characters, Red Anjou recorded maximum fruit length (6.88cm), fruit diameter (5.77cm), fruit weight (111.36g) and fruit volume (118.48cm2), followed by Coscia for all these characters. No significant variation was recorded for L/D ratio among the pear cultivars. Maximum fruit firmness (20.77 lb/inch2) was scored by Cosco-D. Coscia registered maximum TSS (14.04%) along with minimum acidity (0.30%) and highest TSS/acid ratio (46.80). Highest reducing sugar (7.92%) and total sugar (9.26%) was scored by Coscia, followed by William Bartlett as 6.77% of reducing sugar and 7.96% of total sugar. From the present study it is clear, that Red Anjou and Coscia performed well under Kashmir conditions and is suitable for commercial purpose.Keywords

The main objective of conducting the current study was to evaluate the chemical compositions of different chemically-enriched composts prepared by the methods of pit and heap and compare it with conventional compost. The various composts viz., phosphocompost (PC), nitrogen-enriched phosphocompost (NPC), phosphorus-enriched vermicompost (PVC) and vermicompost (VC) were compared with conventional compost. These composts were produced by using chemical amendment in case of chemically- enriched compost whereas vermicompost was prepared by inoculating the epigeic earth worms (Eisenia foetida) with and without rock phosphate. Mineral matter content, ash and moisture were higher in all enriched composts and vermicompost in comparison to conventional compost whereas as total organic carbon, water soluble carbon and C: N were higher in conventional compost. There was higher variation in the content of nutrients in different composts as that of the conventional one but nitrogen and phosphorus were higher in nitrogen enriched phosphorus-compost and phosphorus enriched vermicompost. Zinc was higher in nitrogen enriched phosphorus-compost, vermicompost and phosphorus enriched vermicompost whereas manganese was higher in vermicompost and phosphorus enriched vermicompost. The time period of decomposition was almost similar (120±5) among the enriched composts, whereas in case of conventional compost, decomposition period was (160±10). Biochemical quality stated that conventional compost had lesser amount of total phenol, alkaline and acid phosphatase enzyme activity but higher dehydrogenase activity than those of enriched composts. The more dehydrogenase activity in conventional compost is an indicator of partial decomposition of the compost. The vermicompost was better than conventional compost; it could be still further improved by rock phosphate enrichment.Keywords

The present investigation on effect of different growth regulator combinations on the per cent media browning in walnut in vitro studies using MS medium was carried out in order to document the available genetic variability in walnut germplasm and to select elite walnut genotypes possessing superior attributes and quality traits. During the survey, data was recorded on one hundred fifty two (152) walnut trees growing in different areas of Kashmir valley. The study also involved establishment of response of elite walnut selections to different plant growth regulators in shoot morphogenesis. Woody species have been found to be far more difficult to clone in vitro than herbaceous plants. Poor response of the explants from mature woody species to in vitro manipulation is usually associated with the problem of browning and explant necrosis. The present studies were conducted on forced explants from three walnut selections (SKUAST 002, SKUAST 008, SKUAST 010). Murashiage and Skoog's basal medium supplemented with 0.3 mg/l-1 Benzylamino purine and 0.1 mg/l-1 indole-3-butyric acid gave best response in the establishment of initiating cultures, minimum media browning (80.44 %), minimum explant browning (78.22 %) and minimum mean browning score per explant (9.17 %). The survival (23.45%) and growth of the cultures (21.77%) was also found to be maximum in MS medium supplemented with BAP 0.3 mg l-1 and IBA 0.1 mg l-1.Keywords
