Morphogenic and Molecular variability of Fusarium oxysporum f.sp. lycopersici isolates causing wilt of tomato

Paper ID- AMA-06-11-2022-11788

Fusarium wilt of tomato, caused by Fusarium oxysporum f.sp. lycopersici (Sacc.) is one of the major constraints in tomato production in Rajasthan. The present study was undertaken to investigate the cultural, morphological and molecular variability among ten isolates of Fusarium oxysporum f.sp. lycopersici recovered from various locations of Rajasthan. Among the isolates maximum mycelial growth (90 mm) and maximum sporulation (4.6 x 106/mm2) with whitish regular fluffy growth at middle and light yellow-white pigmentation was recorded in Udaipur isolate (UDPA Fo-1). Whereas, isolate CHTT Fo-7 from Chittorgarh showed minimum mycelial growth (72 mm) and (2.6 x 106 conidia/mm2) sporulation and fluffy growth with deep serrated margin and white colony color with creamy-white pigmentation. The size of macro and micro-conidia measured highest in isolate CHTG Fo-8 with 22.6 (22.1-23.4) × 5.72 (5.41-6.01) µm and 5.89 (5.68-6.10) x 3.04 (2.98-3.1) µm length, respectively. The minimum length and width of macro and micro-conidia was measured in isolate UDPA Fo-1 7.8 (7.2-8.4) x 2.17 (1.95-2.4) µm and 4.05 (3.9-4.2) x 1.10 (1.0-1.21) µm respectively. Molecular characterization of the isolates was performed by using reproducibility of PCR amplification. A total of 10 RAPD primers were used and total 121 reproducible bands were amplified, out of which 94 (77.6%) were polymorphic and 27 (22.3%) were monomorphic. Similarity coefficient among the isolates ranged from 1.8 percent (BNSH Fo-9 and PRTB Fo-3) to 68.9 percent (CHTGFo-8 and JPRDFo-5). Genetic similarity co-efficient was relatively low among all the isolates, which ranged from 0.018 to 0.68. The maximum similarity value (0.689) was obtained between isolates CHTG Fo-8 and JPRD Fo-5.

EFFECTS EVALUATION OF BOTANICALS, BIO-AGENTS AND FUNGICIDES AGAINST Fusarium oxysporum f. sp. ciceri CAUSING WILT DISEASE IN SUSCEPTIBLE VARIETY OF CHICKPEA (JG- 62) UNDER IN-VIVO (POT CULTURE) CONDITION

Paper ID- AMA-04-11-2022-11787

Pulse crops play an important role in Indian agriculture, besides being rich in protein, they sustain the productivity of the cropping system. Ascochyta blight, Fusarium wilt and dry root rot are major diseases of chickpea. Among of all these the wilt disease of chickpea which is caused by Fusarium oxysporum f. sp. ciceri has been considered as divesting one to cause 10 to cent percent loss in yield of chickpea. This pot experiment was conducted for two consecutive years of 2019-20 and 2020-21 in completely randomized design with four replications and five treatments included its suitable control in pot culture under field conditions (in-vivo). The seed of highly wilt susceptible variety (JG- 62) of chickpea was taken for this investigation.It was valuated that only two botanicals viz., Azadirachta indica and Parthenium hysterophorus were found most effective in reducing the wilt incidence disease 4.25 and 5.37 percent, respectively, along with this seed germination percentage and seedling emergence was found also higher in Azadirachta indica as 23.00 and 19.25 percent, respectively followed by Parthen in compression of Lantana camara and Argemone mexicana. In case of bio-agents results were valuated that’s, only two bio-agents viz., Trichoderma viride and T. harzianum were found most effective in reducing the wilt incidence disease by 4.75 and 5.50 percent, respectively, along with this seed germination percentage and seedling emergence was found maximum in Trichoderma viride as23.87 and 22.25 percent, respectively followed by T. harzianum as 21.5 and 18.62 percent, respectively in compression of T. hamatum and T. koningiiand in the case of fungicides, results were revaluated that’s, only two fungicides of different groups viz., Carbendazim 12% + Mancozeb 63% (combi-fungicides) and Carbendazim (systemic fungicide) were found most effective in reducing the wilt incidence disease 1.50 and 2.62 percent, respectively, along with this seed germination percentage and seedling emergence was found maximum in Carbendazim 12% + Mancozeb 63% as 24.25 and 22.75 percent, respectively followed by Carbendazim as 23.25 and 21.62 percent, respectively. Minimum effectiveness was recorded in non-systemic fungicide namely Chlorothalonil 75% WP during this investigation into the pot culture under in-vivo (field conditions).

Paper ID- AMA-04-11-2022-11785

A field experiment was carried out at ICAR-Krishi Vigyan Kendra, Tiruvallur to study the integrated crop management practices on yield and economics of brinjal at Tiruvallur District of Tamilnadu. Farmers were cultivated local varieties, adopted local technologies, getting low income, low yield and unaware new technologies for cultivation of brinjal. The studies were conducted on effect of integrated crop management practices on brinjal yield and economics through frontline demonstration at farmer’s field of Tiruvallur district, Tamilnadu during the year 2016-2017. Inputs like IIHR-Arka Vegetable Special, Pseudomonas fluoresences, Wota – T traps and yellow sticky traps were purchased and distributed to the ten identified farmers. There was significantly increased in brinjal yield (36.7 per cent), net return and B:C ratio after conduct of frontline demonstrations as compared to farmers practice. The adoption of integrated crop management practices through demonstrations programme, showed positive impact on brinjal yield and economics. Demonstration plot recorded higher technology gap (22.0 t/ha), extension gap (6.0 t/ha) and technology index (36.6 per cent), compare to local variety and also showed high percentage yield increase over local type and recorded 20 per cent increase yield.

Paper ID- AMA-04-11-2022-11784

Hot pepper or Chilli (Capsicum annuum L.) is an important and widely cultivated vegetable and spice crops of India (Arun Kumar, 2006). Assessment of chilli hybrids for growth, yield, economics and higher productivity was conducted in five different farmer’s field during the year 2017-2018 at Ellapuram and Ekkadu blocks under on farm trial to know about the performance of chilli hybrids Viz., TNAU CO (ch)1 and IIHR Arka Harita. Several growth, yield and economical characters of the two hybrids were studied in comparison with the local variety Arani local chilli. The results showed that Arka Harita exhibited the highest values for growth, yield and economic traits. The growth characters like plant height (49.5), number of fruits per plant (81.20), fruit length (10.4 cm), market preference (very good) were observed the highest values in Arka Harita followed by TNAU CO (ch)1 (48.42 cm, 77.8, 10.7 cm and good) whereas local variety recorded the lowest values (44.26 cm, 65.4, 10.0 cm and average). Arka Harita recorded the minimum number of days for 50 per cent flowering (42) and number of days to 1st harvesting of fruits (80.48). Arka Harita recorded the highest number of fruits per plant (81.2) followed by TNAU CO (ch)1 is (77.8) whereas the local variety registered the lowest number of fruits per plant of 65.40. Regarding yield characters, Arka Harita recorded the highest fresh pod yield (29.04 t/ha) and dry pod yield (6.0 t/ha) followed by TNAU CO (ch) 1 (fresh pod 26.6 t/ha and dry pod 5.3 t/ha) whereas local variety recorded the lowest yield of 18.8 t/ha as fresh pod yield and 1.8 t/ha as dry pod yield. With respect to benefit cost ratio, Arka Harita recorded the highest ratio of fresh pod (3.05) and dry pod (5.58) with the net profit of fresh pod (Rs.2,34,487) and dry pod (Rs. 5,21,897) followed by TNAU CO (ch)1 of fresh pod (2.76) and dry pod (5.08) with the net profit of fresh pod (Rs.1,95,781) and dry pod (Rs.4,40,486) respectively, whereas local variety observed the lowest BC ratio (fresh pod 1.82; dry pod 1.52) and net profit for (fresh pod Rs.97,177; dry pod Rs.59,559). Thrips incidence was low in Arka Harita (25.4 per cent) when compare to local variety (16.4 per cent). Arka Harita recorded higher technology gap (2.96 t/ha), extension gap (10.2 t/ha) and harvest index (10.1 per cent), compare to local variety and also showed high parentage yield increase over local type and recorded 54.10 per cent increase yield.
