Abstract Niger (Guizotia abyssinica Cass.) is an important minor oil seed crop grown in dry areas grown mostly by tribal and interior places as life line of tribal segment. Tribal people mainly use its oil for cooking purpose, above than that there were also other uses. Hence, the niger crop should be protected from the infection. The crop is affected by number of fungal diseases. Therefore, a field experiment was formulated for three years with the four replications at the Niger Research Station (NRS) at Navsari Agricultural University (NAU), Vanarasi, Navsari (Gujarat) on the foliar diseases of GN-1 variety of niger crop. In this experiment, six different fungicides along with one control have been evaluated to control the Alternaria and Cercospora leaf spot diseases, out of which all the fungicidal treatments were significantly superior over the control. Here, foliar spray on the incidence of diseases was compared with the control (without any treatment). All the fungicidal treatments were significantly superior over the control to reduce Alternaria and Cercospora leaf spot diseases of Niger crop. Treatment of Carbendazim + Mancozeb (0.2 %) with two sprays first from the initiation of the disease and second after the interval of 15 days recorded the lowest incidence of Alternaria (14.56) and Cercospora (14.94) leaf spot diseases of niger and recorded the highest seed yield 337 seed yield kg/ha along with the net return with cost benefit ratio graph.

Front line demonstrations (FLDs) were conducted by pearl millet Research Station, JAU, Jamnagar on 313 farmers’ field in 125 hectares of different 98 villages of Gujarat state during summer season of 2015 to 2019. Prevailing farm practices were treated as control for comparison with recommended package i.e. improved variety (GHB 558, GHB 538, GHB 732), seed rate 4 kg/ha, timely sowing (15 Feb to 15 March), line sowing with spacing of 60 cm (R-R) and 10-12 cm (P-P), balanced use of fertilizers (NPK @120:60:0 kg/ha, thinning 15 days after sowing, weed management (pre emergence spray of Atrazin @ 0.5 kg/ha and one hand weeding), proper critical stage apply 8-10 irrigation, two foliar spray of profenophos 0.05 % at 20 and 40 days after germination to control shoot fly and stem borer pests infesting pearl millet, timely harvesting and threshing. The cumulative effect of technological intervention over five years, revealed average grain yield 4362 kg/ha and dry fodder yield 7365 kg/ha which is 6.17% and 12.76% higher over the farmers’ practices. The economics and cost benefit ratio of both farmers’ and improved practices was worked out. On an average net profit was obtained 6837 /ha due to adoption of improved package of practices. The average cost benefit ratio was 2.23 under improved demonstration practices, while it was 2.43 under farmers’ practices. By conducting the Front line demonstrations of proven technologies, yield potential and net income from pearl millet cultivation can be enhanced to a great extent with increase in the income level of the farming community.

AbstractNiger (Guizotia abyssinicaCass) is an important minor oilseed crop of hilly and tribal regions and it is used for oil as well as for various other purposes only by the tribal people. Therefore, a systematic study was arranged to document about the increase in the seed yield of niger crop in relation to honeybees (Aphis mellifera), as a pollinator in niger crop with paired plot technique at the Niger Research Station (NRS) at Navsari Agricultural University (NAU) and at farmer’s field, Vanarasi, Navsari, Gujarat (India) and also studied its relation in terms of cost benefit ratio (CB). The trial was conducted at Niger Research Station (NRS), Vanarasi for 3 years (2013-14, 2014-15 and 2015-16) and also at farmer's field to ascertain the role and involvement of honey bees (Aphis mellifera) in swelling the seed yield of niger crop (due to pollination) and its effect on income due to increase in the niger seed yield. Significant differences were observed for number of capitula/plant, number of seeds/capitula, 1000 seed weight and seed yield in both the location for the consecutive 3 years. However, the seed yield and gross returns were considerably higher in first location of T1Natural plot/open pollinated with beehive (Aphis mellifera)in all the 3 years data with the maximum seed yield with the gross return was obtained in this treatment.

Background: Pod fly, Melanagromyza obtusa is one of the most obnoxious pest causing grain damage ranging from 10-80% with a monitory loss of US$ 256 million annually. Being an internal feeder, infested pods do not show any external symptoms of damage until the fully grown maggots chew the pod wall, leaving a thin papery membrane intact called as window, through which adults exit from the pod. Several field studies were conducted to determine the efficacy of insecticides for the control of pod fly. However, these findings did not find acceptability and led to partial success. Insecticides that should leave lesser residues and pose lesser environmental threat have become imperative. The present study aimed to evaluate the efficacy of certain new insecticide molecules against pod fly in pigeonpea ecosystem. Methods: Two field experiments were conducted at Regional Agricultural Research Station, Lam, Guntur during Kharif, 2012 and 2013 in a randomized block design (RBD) using pigeonpea cv. ICPL 85063 (Lakshmi) with 17 treatments including untreated control and 3 replications. Two sprays were given at 10 days interval starting from pod initiation stage. At maturity, number of pods showing pod fly damage were recorded and expressed as percentage. Grain yield was recorded and cost–benefit ratio was worked out. Result: Among different insecticides, thiacloprid 21.7 SC, followed by diafenthiuron 50 WP, flubendiamide 480 SC and dimethoate 30 EC were very effective against pod fly with more grain yield and registered highest incremental cost benefit ratio (ICBR). It was further suggested that effective insecticides may be alternated in order to avoid development of resistance to pod fly in pigeonpea.

An experiment was conducted at Zonal Agricultural Research Station, V.C farm, Mandya (Karnataka), India during 2015, to assess the chemical control of sugarcane early shoot borer (Chilo infuscatellus). Nine insecticides namely, Fipronil 0.3G, Chlorantraniliprole 0.4G, Chlorantraniliprole 18.5 SC, Spinosad 45SC, Flubendiamide 39.35SC, Cartap hydrochloride 4G, Phorate 10G, Carbofuran 3G, Chlorpyriphos 20EC, and compared with untreated (Check plot)using randomized block design with three replications. Significant differences were noticed among the treatments. Chlorantraniliprole 0.4G recorded lowest cumulative incidence (2.79 %) and highest per cent reduction over the control (85.78 %) which was followed by Cartap hydrochloride 4G (5.37% and 72.65%), Chlorantraniliprole 18.5 SC (5.95% and 75.62%), Flubendiamide 39.35SC (6.64% and 66.19%) and Fipronil 0.3G (6.83% and 65.22%) were found significantly superior in reducing the cumulative incidence of C. infuscatellus.In Co 86032 Cartap hydrochloride 4G was found to be the best insecticide in getting a highest cost benefit ratio (1:12.39). Other insecticides such as Fipronil 0.3G (1:8.84), Chlorantraniliprole 0.4G (1:6.96), Flubendiamide 39.35SC (1:5.42) and Spinosad 45SC (1:4.16) have also recorded better cost benefit ratio. Since Cartap hydrochloride 4G does not have crop label so we can recommend Fipronil 0.3G or Chlorantraniliprole 0.4G for the management of sugarcane early shoot borer.

Turmeric leaf spot, caused by the pathogen Colletotrichum capsici, is the greatest damaging disease that limits the production and productivity of turmeric, and reduces qualitative and quantitative rhizome yields in Southwestern Ethiopia. A field trial was conducted to evaluate the efficacy of different fungicides against a disease epidemic of turmeric leaf spot in Southwestern Ethiopia. The field experiment was performed at Tepi Agricultural Research Center during the 2019 and 2020 main cropping seasons using four fungicides: Ethiozeb 80% WP (mancozeb), Prozole 255 EC (propiconazole), Mancolaxyl 72% WP (mancozeb + metalaxyl) and Ridomil Gold MZ 68 WG (metalaxyl-M), which were applied either as seed rhizome treatments plus foliar spray, or as foliar spray alone for control of leaf spot infection. The field experiment was laid out in a randomized complete block design with nine treatments and three replications. The results of the experiment indicated that both rhizome treatment + foliar spray, and foliar fungicide spray treatments significantly affected the turmeric leaf spot epidemics. The effect of the foliar spray Prozole 255 EC (propiconazole) was significantly higher than the other treatments in reducing disease severity (27.0) and maximizing rhizome fresh yield (34.1 ton/ ha). The maximum cost benefit ratio (1:2.65) was achieved by the foliar spray fungicide Prozole 255 EC (propiconazole). Amongst different fungicides considered, the foliar spray Prozole 255 EC (propiconazole) reduced leaf spot disease incidence up to 47.1% over the control on the last day of disease evaluation. The whole outcome of this experiment showed that foliar Prozole 255 EC (propiconazole) fungicide sprays were effective in alleviating the epidemic of turmeric leaf spot and boosting turmeric production and productivity.

Productivity of lentil in rainfed ecology is very low and crop was infested with different soil and seed born fungal disease. In light of fragment information available on response of seed treatment with Trichodermaharzianum strains S1 and S3, a field experiment was conducted during winter seasons of 2013-14 and 2014-15 at experimental farm of KrishiVigyan Kendra, Buxar and farmers field. Among different seed treatment practices coupled with IRRI BMP, Trichoderma strain S3 produced the highest number of pods/plant (59.6) and 100-grain weight (2.60 g) followed by seed treatment with S1+ IRRI BMP and Thiram+IRRIBMP. However, farmers’ practice recorded lowest value of all these traits. Highest number of nodules/plant (15.80) and dry matter of nodules, (37.12 mg/plant) were recorded under seed treatment with S3+IRRI BMP followed by S1+IRRI BMP and Thiram+IRRI BMP in order. Seed treatment with S3+IRRI BMP recorded highest root length (25.2 cm), root dry weight (0.90 g/plant) and seed yield (13.33 q/ha) followed by seed treatment with S1+IRRI BMP and Thiram+IRRI BMP in order. However, farmers’ practice recorded minimum value of these traits. Economic analysis of data showed that maximum net return (Rs 23489/ha) and cost-benefit ratio (2.42) was recorded under seed treatment with strain S3+IRRI BMP followed by seed treatment with S1+IRRI BMP and Thiram+IRRI BMP. However, minimum economic return was recorded with farmers’ practice.

ABSTRACT: Chickpea is the third most important crop of rainfed areas of Pakistan, and it is severely affected by noxious weed Asphodelus tenuifolius. Therefore, a field trial was conducted to evaluate the effect of different allelopathic weed extracts, herbicides and mulches in controlling A. tenuifolius and other associated weeds in chickpea at “District Karak” Khyber Pakhtunkhwa-Pakistan. The experiment was carried out in a Randomized Complete Block Design (RCBD) and replicated thrice using a chickpea cultivar (Chattan) which was grown for the experimental trial. There were 9 treatments along with control for comparison. The treatments Stomp 330 EC (Pre-emergence) at 2.5 L ha-1, Fenoxaprop-p-ethyl, Bromoxanil+MCPA (Tank mix), Starane-M, mulching (Eucalyptus leaves), mulching (Wheat straw mulch), allelopathic weed extract (A. tenuifolius) + Stomp, allelopathic weed extract (Cyperus rotundus), allelopathic weed extract (Sorghum halepense) and control treatment were used in this trial. Data were recorded on A. tenuifolius density m-2 before and after application of weed management practices (m-2), A.tenuifolius fresh weight (m-2), seed yield (kg.ha-1), biological yield (kg ha-1) and cost-benefit ratio. Weed density before weed management was found to be non-significant. The data showed that minimum A. tenuifolius density after weed management and fresh weight (m-2) were found for Stomp 330 EC (6.33 m-2 and 1.98 kg m-2), which is statistically similar to Fenoxaprop-p-ethyl 6.9 EC (10.33 m-2 and 3.03 kg m-2) while maximum A. tenuifolius density and fresh weight (m-2) were recorded for control plots (74.33 m-2 and 287.46 kg m-2). Maximum seed yield (1,781.7 kg ha-1), biological yield (3,823 kg ha-1) and cost-benefit ratio (3.47) were recorded for plots treated with Stomp 330 EC, while the lowest seed yield (851.7 kg ha-1), biological yield (3,126.3 kg ha-1) and cost-benefit ratio (1.53) were observed for the control plot. Among the nutritive parameters in chickpea, maximum crude protein (17.40%), crude fat content (4.90%) and oil content (5.98%) were recorded for plots treated with Stomp 330 EC, while minimum crude protein (16.18%), crude fat content (4.12%) and oil content (5.01%) were found in the control plots. Thus, it is recommended that herbicides Stomp 330 EC and Fenoxaprop-p-ethyl should be used at pre-emergence at their recommended doses for control of A.tenuifolius and other associated weeds in chickpea crops.

 Bodyweight exercises (also popularly known as calisthenics) is a classic training method and its practice has been widespread since the 19th century, but little evidenced in the scientific literature over the years. This type of training aims to promote multi-system adaptations using body weight as an overload with no or few implements [1–3]. This characteristic makes exercise with body weight easy to apply, in addition to having an excellent cost-benefit ratio when compared to other training possibilities that require machines or materials [4,5].
