The study aims at finding the extent of farmers knowledge about happy seeder technology of wheat sowing in standing paddy stubbles and correlation with their personal attributes, was conducted in Ambala & Kurukshetra district of Haryana state with the sample of 160 respondents of twenty villages. As per results, however, majority of the farmers were belonged to full and partial level of knowledge about some Aspects/Items (Those were related to benefits of happy seeder and suitable type of tractor for operating it), out of Thirteen Aspects/Items, selected and listed in interview schedule for the study, such as Happy seeder is a time and fuel-saving technology, Happy seeder technology is an Eco-friendly technology, Happy seeder improves soil health and, Compatible tractor type and its HP for operating the machine. But, even that, they had little knowledge about the remaining Aspects/Items, Therefore, their overall knowledge about the HS was less, in fact, the majority of farmers possessed a low level of expertise about Happy seeder technology as a whole. So, most of the respondents were belonged to low level category of Overall knowledge towards Happy Seeder Technology. In case of personal traits, it was found that those attributes which had taken in the study, were found to have positively correlated but only one trait i.e. age was negatively correlated with knowledge level of farmers.
Field experiments were carried out to study the effect of nanofertilzers on yield attributing characters and yield of okra (Abelmoschus esculentus L.) at the Agriculture Research Station, Binjhagiri, Chatabara, Institute of Agricultural Sciences, Siksha ‘O’ Anusandhan (Deemed to be University), Bhubaneswar, during February 2021-May 2021. The experiments were laid out in Randomized Block Design with three replications and fifteen treatments viz., Control (only FYM) T1,75% RDF (Conventional fertilizer in soil) T2, 100% RDF (Conventional fertilizer in soil) T3,75% RDF + IFFCO Nano Nitrogen (Foliar spray) @ 3 ml/l T4,75% RDF + IFFCO Nano Nitrogen (Foliar spray) @ 4 ml/l T5,75% RDF + IFFCO Nano Nitrogen (Foliar spray) @ 5 ml/l T6,100% RDF+ IFFCO Nano Nitrogen (Foliar spray) @ 3 ml/l T7,100% RDF+ IFFCO Nano Nitrogen (Foliar spray) @ 4 ml/l T8,100% RDF+ IFFCO Nano Nitrogen (Foliar spray) @ 5 ml/l T9,75% RDF+ Geolife N:P: K (19:19:19) @ 1 g/l T10,75% RDF+ Geolife N:P: K (19:19:19) @ 2 g/l T11,75% RDF+ Geolife N:P: K (19:19:19) @ 3 g/l T12,100% RDF+ Geolife N:P: K (19:19:19) @ 1 g/l T13,100% RDF+ Geolife N:P: K (19:19:19) @ 2 g/l T14, 100% RDF+ Geolife N:P: K (19:19:19) @ 3 g/l T15. The present study revealed that the maximum plant height (107.41 cm), was obtained with T3 +IFFCO Nano N(Foliar sprays @ 3 ml/litre), whereas maximum fruit length (14.26 cm) and maximum fruit weight(16g) was obtained with T3 + Geolife NPK(19:19:19) @2g/l. The maximum yield per plant (193.93 g) was recorded with T2 +IFFCO Nano N (Foliar sprays @ 4 ml/l).
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.
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).
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.
