The present investigation was carried out at experimental research farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu at Chatha during 2019-20 and 2020-21. Eight genetically diverse cultivars of strawberry were selected based on their genetic value and crossed through hand self-pollination and caging methods of pollination to produce inbreed lines of cultivars. After crossing of genetically superior parent by two different pollination methods viz., hand self-pollination and pollination by caging, Nabila showed best results among different cultivars. In hand self-pollination, fruit set after 21 days was found to be maximum in Nabila cultivar i.e. 83.32 % and 85.40 % within two growing season, respectively. Simultaneously, cultivars Nabila showed maximum fruit retention (82.90 % and 84.63 %), fruit weight (30.12 g and 31.16 g), fruit length (38.60 mm and 42.70 mm), fruit breadth (43.20 mm and 44.22 mm), number of achenes per fruit (411.75 and 435.75), achene density (17.77 cm2 and 15.66 cm2), respectively. However, cv. Jutog Special showed lowest performance among all these parameters. In self-pollination by caging, fruit set after 21 days was found in cv. Rania (60.32 % and 61.44 %), fruit retention in cv. Nabila (62.18 % and 64.70 %), fruit weight in cv. Nabila (16.49 g and 17.26 g), fruit length in cv. Rania (25.86 mm) in 2019-20 and cv. Nabila (28.13 mm) in 2020-21, fruit breadth in cv. Nabila (16.16 mm and 16.26 mm), number of achenes per fruit (246.32 and 251.14) and achenes density (22.77 cm2) in 2019-20 and 24.06 cm2 in Sweet Charlie in 2020-21. However, maximum fruit set after 21 days were recorded by hand self pollination methods which resulted into maximum fruit retention, fruit weight, fruit length, fruit breadth etc. as compared to self pollination through caging. Hand self-pollination methods is best methods to develop fruit under controlled condition and ensure the pollination in strawberry cultivars to develop inbred lines.

Correlation of aonla orchards to soil nutrient status with growth, flowering and fruiting characteristics

Paper ID- AMA-06-08-2022-11591

A survey was carried out to study the correlation between available soil nutrients with growth, flowering and physico-chemical characteristics of 110 aonla fruit orchards of Akhnoor, Raya and Purmandal areas of Jammu subtropics during 2016 and 2017. The soil nutrients status in these aonla orchards varied from 79 to 536.50 kg/ha nitrogen (N), 4.65 to 17.57 kg/ha phosphorus (P), 36.65 to 235.95 kg/ha potassium (K), 6.3 to 13.81 mg/kg sulphur (S), 0.31 to 7.18 mg/kg zinc (Zn), 1.37 to 16.76 mg/kg iron (Fe), 0.34 to 4.8 mg/kg copper (Cu) and 0.11 to 2.94 mg/kg manganese (Mn). The relationship between tree height, tree spread and tree volume with soil N, P, K, Zn, Cu and Mn were found to be positive and significant. A negative but significant relationships of soil N was found with duration of flowering while as the total numbers of flowers and male flowers had highly significant correlation with N, P, Zn, Cu and Mn. The relationship of soil N, P, Cu and Mn were found to be highly significant with fruit weight, length, diameter, volume, pulp weight, dry weight of pulp, stone weight and pulp: stone ratio, while as negative significant correlation of specific gravity with P, Fe and Cu. Soil N, P, K, Mg, Zn, Fe, Cu and Mn exhibited positive and significant relationship with TSS, TSS: acid ratio, total sugar, reducing sugar, ash content, pH, protein, polyphenols and starch.

Yield and quality of aromatic rice (Oryza sativa L) as influenced by organic nutrient management in rainfed condition of Assam

Paper ID- AMA-04-08-2022-11589

A field experiment was conducted at Instructional-cum-Research Farm of Assam Agricultural University, Jorhat, Assam, India during kharif season of 2018 and 2019 to study the effects of organic nutrient management on growth, yield attributes, yield and quality of aromatic rice varieties. The variation in the growth, yield attributes and yield among the aromatic rice varieties was found significant and the highest grain yield was recorded in Keteki joha which was found to be statistically at par with Chakhao poireiton. Among the organic nutrient management treatments, application of vermicompost @ 30 kg N/ha+ in situ green manuring with Sesbania aculeate+seedling root dip treatment with Azospirillium and phosphorus solubilizing bacteria (PSB) @ 3.5 kg /ha each (N3) produced the highest number of panicles /m2, longest and heaviest panicle and the highest grain and straw yield during both the years. The quality profile in terms of crude protein content and content of Fe, Zn, Mn were influenced by the organic nutrient management and found highest with the N3 treatment. The aromatic rice varieties showed significant variations in their quality parameters. The cultivar Kola joha was found superior in respect of Fe, Zn and Mn content whereas Keteki joha was found superior in respect of crude protein, Ca and Mg content, head rice recovery percentage and length and breadth ratio over others. The lowest amylose content (6.23%) was recorded in case of Chakhao poireiton.

Succession of Pea Insect Pests and their Natural Enemies in Rainfed Sub Tropics of Jammu and Kashmir region of N-W Himalayas

Paper ID- AMA-02-08-2022-11582

Major insect pests and their natural enemies, prevalent in field pea crop of Jammu and Kashmir sub tropical Kandi areas were recorded. This shall help in targeting the major insect pests at the right time/stage for applying appropriate protection measures. Experiments were conducted to record the pest and their natural enemies’ population fluctuation, at different phenophases of the crop. Eleven different pea varieties were sown in randomized block design, replicated thrice in a plot size of 3 x 4 m2, maintaining a plant to plant distance of 5-6 cm and row to row distance of 30 cm. Leaf miner and aphids were found to be the two major insect pests of pea in this region and the predator ladybird beetle, and parasitoid quite effectively kept the aphid population under check. Pea leaf miner infestation started with the 45 days old crop and its infestation varied among the different varieties. Lowest leaf miner infestation was recorded in US-10, which was at par with the variety Sweet pearl and MGS-10. However, significantly highest leaf miner infestation was in popular varieties Green Valley, Rachna and Prakash. Significantly highest per cent parasitization was recorded in GS-10 variety which was at par with KIWI-101, Prakash and Green Valley. However, per cent parasitization by aphid parasitoid ranged from 44.50 - 56.20 per cent during Rabi 2016-17 and 46.50 - 52.40 per cent during Rabi 2017-18 irrespective of the different varieties. Significantly superior predator counts were also observed in US-10, Varun Dhara, Rachna, DS-10 and MGS-10. Management strategies for leaf miner should preferably be started, when the crop is 45 - 50 days old as irrespective of the varieties, the leaf miner population started appearing after 35 - 40 days of sowing and reached its peak during 45 - 50 DAS. Fifty per cent of the aphid population is kept under check by its predator and parasitoid. Management strategies should be therefore modified accordingly, so as to cause least harm to the natural enemy population.

Paper ID- AMA-01-08-2022-11579

A laboratory study was conducted during 2020-21 in the laboratory of the Department of Entomology, Institute of Agricultural Sciences, SOADU, Bhubaneswar, Odisha, to identify plant powders which may prove effective against rice weevil, via; Azadirachta indica (A. Juss.) seeds and leaves, Pongamia pinnata (Linnaeus), Calotropis procera (Aiton), Annona reticulata (Linnaeus), Lantana camara (Linnaeus), Vitex negundo (Linnaeus) leaves, Capsicum annum (Linnaeus) dried fruits and Curcuma longa (Linnaeus) rhizome at 5% and 10% concentration. This study revealed that the pest could oviposit 3.55 to 24.52 eggs in different treatments. Lowest oviposition (8.06 and 3.55) was there in Neem Seed Kernel (NSK) Powder treatment. Chili powder and Calotropis leaf powder were also effective in reducing egg deposition. The egg to adult period was maximum in NSK Powder (34.5 and 41.3 days) and minimum in Lantana leaf powder recording 24.52 and 19.68 days. Adult emergence% was maximum in Lantana leaf powder (41.94 and 37.12) and minimum in NSK Powder (6.12 and 2.40). Longevity of males was found to be the highest in Lantana leaf powder (21.7 and 16.5 days) and lowest in NSK Powder (2.2 and 1.6 days). Same trend was also found in case of females with 22.2 and 18.9 days in Lantana leaf powder and 2.6 and 2.0 days in case of NSK Powder. Mortality was observed to be the most in NSK Powder ranging between 97.24 and 99.70% and minimum in case of Lantana leaf powder ranging between 23.87 and 46.57%, all at 5% and 10% concentration, respectively.
