Red onion is used for domestic consumption and export while the white onion is used mostly for processing. Improvement in garlic has been largely through clonal selection and mutation breeding. Somaclonal variations for development of varieties have not been used till now. Research on biotechnology for crop improvement in onion and garlic in India is in a nascent stage. ...

Seedling root dip and foliar application treatments were evaluated with carbosulfan, imidacloprid, and chlorpyriphos during Rabi season to manage the pest. Seedling root dip with carbosulfan @ 0.025% protected the young plants up to 30–40 days from thrips infestation. Carbosulfan @0.05% as seedling root dip at higher doses for 6h and 12 h resulted in phytotoxicity. Foliar application of carbosulfan @0.05% was found very effective in bringing down the thrips population compared to monocrotophos, chlorpyriphos and imidacloprid. The combination treatment, seedling root dip followed by foliar sprays of carbosulfan effectively reduced thrips and recorded highest marketable yield.

Rabi season plantings (1 November - 15 December) were severely attacked by onion thrips, Thrips tabaci Lindeman followed by kharif plantings (1 June -1 August). Thrips infestation was highest on crop planted on 15 - November (70.39/plant) followed by 1 - December planting (59.6/plant). Late kharif plantings (15 August - 15 October) were comparatively safer from thrips damage. Onion crop transplanted on 15 - August and 1 - September attracted lowest number ol thrips (5.48/plant). Highest marketable yield of 44.44 llha was obtained in I5 — September plantings followed by 1— October. Yield loss up to 46.87% was recorded in rabi season due to thrips attack. Variations in yields even under low thrips population may be due to seasonal variations.

It is indigenous to India and West Indies. In Maharashtra (India), it has gained attention in recent years and since last decade farmers have established jamun orchards of variety Konkan Bahadoli. Jamun reaches the height up to 30 m. Fruits are hand plucked as the peel of jamun is very thin. It is necessary to climb jamun tree for harvesting. It is therefore necessary to manage a canopy of jamun which will facilitate the harvesting without affecting the yield level. Hence, the experiment was conducted on canopy management in jamun. Investigation was undertaken at two different locations with two different set of treatments. At each location four treatments which were replicated five times in Randomize Block Design. At location A as well as location B T 2 was superior in respect of per cent plants flowered, per cent flowering intensity and number of flowers per branch let. Similarly, performance of T 2 for number of fruits per branch let, yield per tree (kg/plant) and yield (t/ha) was superior as compared to other treatments. Percentage of sellable fruits was more in T 1 and T 2 as compared to T 3 and T 4. Similarly, time required for harvesting per kg fruits was less in T 1 and T 2 as compared to T 3 and T 4 .
