Effect of supplementation of different Organic Trace Minerals on Production Performance, Immune Response, Carcass characteristics and Cost Economics of Commercial Broilers
An experiment was conducted to investigate the comparative performance of commercial broilers fed KemTrace (mineral propionate) with other organic minerals. The feeding trial was conducted for a period of six weeks with 672 chicks allotted to seven experimental groups each with 12 replicates and each replicate consisting of 8 birds in a completely randomized design. The diets of the treatments were : T1-Basal diet with Blend A (Inorganic- sulphates, oxides and carbonates) @1000gm/mt; T2-Basal diet with Blend B (Proteinates) @500 gm/mt. ; T3- basal diet with Blend C (Propionates with antioxidants)@250 gm/mt.; T4- Basal diet with blend D (same as T3 but produced in different process) @350 gm/mt.: T5-Basal diet with Blend E (Propionates, Fumarates with antioxidant) @250gm/mt.: T6-Basal diet with Blend F (Propionates, Fumarates with antioxidant) @500 gm/mt.; T-7 Basal diet with blend G (Butyrates, Propionate, Fumarates with antioxidants) @500 gm/mt of feed. Parameters like growth performance, carcass yield, immune status and trace mineral retention in organs were observed in the broilers. The collected data were analysed using SPSS software Programme version 17.0 and interpreted. The commercial broilers supplemented with metal propionate form of organic mineral performed better than other organic mineral supplementations on growth performance and immune response. Metal propionate form of organic mineral supplemented broilers also showed significantly higher performance on carcass quality and cost economics than other organic mineral supplementations.
Digital Technology, arable land and Sustainable Food Security in Africa
This study examined the influence of arable land and digital technology on sustainable food security in Africa. The study engaged panel data for 51 countries sourced from the Food and Agriculture Organisation (FAO) and World Development Indicators (WDI) for the period 2005 to 2020. The study applied the Generalised Method of Moments (GMM) and the result showed that arable land and digital technology positively and significantly influenced food security in Africa. It showed that a 1% increase in arable land led to an increase in food security in Africa by 22.23%. On the other hand, a 1% increase in digital technology led to an increase in food security by 4.7%. With digital technology, farmers and others may interact with institutions and information that link farmers to the markets and reduce risk and uncertainties. The study concluded that access might encourage large-scale farming capable of promoting sustainable agriculture and rural development. This may directly benefit local communities and smallholder farmers. In addition, access to technological tools will link farmers to the market and connect actors along all nods of the agricultural value chain for improved food security.

The main phytochemicals identified in Moringa and Chekkurmkanis soup cube extracts were 24-Norursa-3,12-diene (21.72%), 24-Noroleana-3,12-diene (19.15%) and Piperine (20.53), 5-Hydroxymethylfurfural (17.61%) 9,12,15-Octadecatrienoic acid, (Z,Z,Z)- (6.315%) respectively. .The study confirmed that the compounds present in the soup cubes has high bioactivities of Antibacterial, Anticancer and antioxidant activities.
PERFORMANCE OF DIFFERENT GRAFTED VARIETY AND MULCHING IN BRINJAL (Solanum melongena L).
A field experiment on grafting three cultivars of brinjal, namely GJB-3, GAOB-2 and Suratiravaiya onto the rootstock of Solanum torvum Swartz was conducted to find out the interaction effect of different grafted and non-grafted varieties and different mulching on plant survival and other horticultural parameters. The variation due to different mulching treatment was found significant for growth and yield parameter. Significantly, highest plant height (113.80) cm), No. of branches per plant (8.97), No. of fruit per plant (12.94), average fruit weight (86.26 gm), marketable fruit yield (1.10 kg/plant and 29.76 t/ha) and lowest days to 50% flowering at TP (49.30), days to first picking (67.96) and days to last picking (173.20) were recorded in treatment M2 (Silver Mulch). Similarly, variety variation was observed significant for growth, yield and yield attributes. Significantly, maximum average fruit weight (107.73 gm), marketable fruit yield, (1.25 kg/plant and 34.78 ton/ha) were recorded with variety (V1): GJB-3 grafted on solanum torvum, whereas, highest plant height (121.18 cm), no. of branches/plant (9.95) and no. of fruits per plant (15.68) were noted in V3: Surtiravaiya grafted on solanum torvum and lowest days to 50% flowering (43.94%), days first picking (67.28) and days to last picking (170.56) were registered with V2 (GJAB-2 grafted on solanum torvum). Interaction effect was found non-significant for maximum character except no. of branches/ plant, no. of fruit per plant and marketable fruit yield. Variation between treatments of mulching was recorded significant for quality and insect pest infestation parameters. Significantly, highest TSS (7.67oB), plant survival (87.59%) and lowest acidity (0.171%), fruit and shoot borer, jassid and white fly infestation (23.24%, 21.81% and 63.59% respectively) were registered with M2 (Silver mulch). For varieties, variation was recorded significant for quality and insect pest infestation parameter. Maximum TSS (8.24oB), minimum acidity (0.102) and fruit and shoot borer infestation (19.72%) were recorded with V3. Whereas, highest plant survival (92.00%) and lowest Jassids and white fly infestation (15.11% and 62.67%) were noted in V2. Interaction effect for quality and insect pest infestation parameters were noted non-significant except TSS and acidity. The farmers of South Saurashtra Agro-climatic Zone growing brinjal are recommended to use variety GJB-3 grafted on Solanum torvum (wild brinjal) with silver black mulch (25 micron) for higher yield.
Distribution of major insect pest and their natural enemies on brinjal and their relation with weather variables under Central Narmada Valley Agro-climatic Zone of Madhya Pradesh, India
Brinjal (Solanum melongena L.) is an important vegetable crop grown in across the world. The production and quality of brinjal is seriously influenced by the attack of insect pests. Two year (2018-19 and 2019-20 Rabi) roving survey revealed that four species of insect pests viz., shoot and fruit borer (L. orbonalis) (4.77-20.47 per cent infestation), whitefly (B. tabaci) (1.48-2.29/plant), jassid (A. biguttula biguttula) (1.94-2.83/plant) and aphid (A. gossypii) (1.09-2.27/plant) and three species of predators viz., ladybird beetle (C. transversalis) (0.37-1.27/plant), green lacewing (Chrysoperla carnea) (0.09-0.29/plant) and spider (Oxyopes sp.) (0.02-0.53/plant) were spatially distributed in all three districts (Hoshangabad, Jabalpur and Chhindwara) and associated with both vegetative and maturity stages of brinjal crop. Moreover, relation of weather variables and weather and crop age based prediction models for major insect pest and their natural enemies were derived through a data generated in a two year field experiment at Rehti, Sehore (Madhya Pradesh). Pearson correlation coefficient revealed that two week prier maximum temp was exhibited significantly positive relation with per cent fruit and shoot borer damage (-0.862**) and count of Ladybird beetle (0.535*). Whereas, jassid (-0.570**), Green lacewing (-0.665**) and whitefly (-0.743**) was significantly negative related with current week (jassid & green lacewing) and one week (whitefly) prier maximum temp, respectively. Likewise minimum temp was also followed similar trend of relation with insect pest and predators. Morning and evening RH had non-significant relation with most of the factors except positive significant with green lacewing. Crop age influenced significantly positive with count of whitefly and shoot and fruit borer and negatively with ladybird beetle. Regression analysis revealed that current week of maximum and minimum temperature, morning and evening RH and crop age were most fitted and accounted 76.9, 77.3 and 94.2 % variability in population dynamics of whitefly (R2 = 0.769), jassid (R2 = 0.773) and shoot and fruit borer damage (R2 = 0.942), respectively. Whereas the similar set of one week and two week prier weather parameters were most fitted for the prediction of green lacewing (R2 = 0.847) and ladybird beetle (R2 = 0.681), respectively. This study will be helpful in management of insect pests through timely application of eco-friendly management practices in the region.
