Digital Technology, arable land and Sustainable Food Security in Africa

Paper ID- AMA-26-04-2023-12222

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.

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

Paper ID- AMA-24-04-2023-12215

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.

Evaluation of disease reaction, yield attributes and yield of chickpea germplasm

Paper ID- AMA-24-04-2023-12214

Chickpea is an important Rabi food legume grown throughout the world. India is the largest producer and contributes 2/3rd of total production of global chickpea. Productivity of chickpea in India is lesser than some other countries due to various factors. Cultivation of chickpea crop is adversely affected by both biotic and abiotic stresses. Among biotic stresses collar rot is an important limiting factor for the production of chickpea. Collar rot incited by Sclerotium rolfsii is an economical disease of chickpea and causes 10-30 per cent yield loss annually. The disease appears moderate form every year in chickpea growing areas. It causes heavy losses in chickpea sown after harvesting of rice having stubbles in cultivated fields. Keeping in view of the serious and economical losses caused by the pathogen, the present study on assessment and identification of germplasm for resistance source and better yield performing genotypes have been conducted during Rabi 2021-22 at Bihar Agricultural University, Sabour, Bhagalpur, India. In the present investigation, two hundred fifty three germplasm were evaluated for their yield and resistance against collar rot under natural sick plot field conditions. Due to continuous growing of breeding material in same field for the last many years, it has high inoculum load. Among evaluated germplasm none of them were found resistant against collar rot disease. However, two hundred fourteen germplasm lines exhibited moderately resistant, twenty two moderately susceptible, eleven susceptible and six genotypes identified as highly susceptible. All germplasm were also assessed for their yield and yield attributing traits in which ICCV 94954 (2937.50 kg/ha), GL-15209 (2845.84 kg/ha), GL-15131(266.66 kg/ha), CSJ 1065 (2645.84 kg/ha), IPC 2011-141 (2595.84 kg/ha), GNG2475 (2591.66 kg/ha) and RSGD 1174 (2562.50 kg/ha) showed moderately resistant reaction as well as better yield performing genotypes which may be utilized for breeding programme for the development promising entries against collar rot disease.
