Estimation of Ranking in Bottle gourd (Lagenaria siceraria (Mol.) Standl.) Genotypes over Diverse Environmental Conditions in Humid and Sub-humid Southern Plains of Rajasthan (India)

Paper ID- AMA-10-06-2022-11455

Vegetables are an important part of a well-nutritious human diet, as well as a key component in achieving nutritional security by providing nutrients, vitamins, and minerals. The plants grow in the humid and sub-humid southern plains of Rajasthan that provides high recompense to growers. Production of bottle gourd is limited due to lack of high-yielding as well as better adaptive cultivars. In order to identify high yielding stable genotypes across the diverse environmental conditions, we have evaluated fifty-eight genotypes of bottle gourd in a Completely Randomized Block Design over three different environments in Rajasthan during summer and late Kharif 2021. According to the Eberhart and Russell model for stability analysis, P1 x P6, P1 x P2, P5 x P6 (bi>1) and P1 x P3, P2 x P5 and P3 x P9 (bi<1) were identified as the most promising genotypes for days to anthesis of first male flower, P5 x P6 and P3 x P8 (bi>1) and P1 x P2 and P4 x P5 (bi<1) for days to anthesis of first female flower whereas P5 x P7 and P7 x P8 (bi>1) and P1 x P3, P2 x P8 (bi<1) for number of branches per plant. P8 x P10, P1 x P2, P6 x P10, P5 x P10 (bi<1) and P4 x P8 and P6 x P7 (bi>1) can be used to increase the leaf area index, whereas, P1 x P6, P6 x P9, P6 x P10 (bi<1) and P2 x P8 and P4 x P9 (bi>1) for fruit diameter and P6 x P9 and P1 x P3(bi<1) and P2 x P8, P8 x P10 and P5 x P9 (bi>1) for fruit weight, and P2 x P6, P3 x P6, P2 x P7, P3 x P5 and one checks “Prince” (bi>1) and P6 x P9, P1 x P10, P3 x P4, P2 x P10 (bi<1) for T.S.S and P2 x P6 and P1 x P6 (bi>1) and P1 x P10, P7 x P8, P7 x P10 (bi<1) for ascorbic acid. Since these genotypes were indicated to be the most consistent across the environments for the traits mentioned, they can be successfully suggested to use in breeding programs. The study revealed that some reliable predictions regarding genotype and environment interaction, as well as its unpredictable components, played a relevant role in genotype stability. With this aim, the current study can be used to identify more productive genotypes in specific conditions, resulting in a large improvement in fruit productivity.

Current statute of agricultural mechanization in Senegal: Case of the groundnut basin (rainfed cultivation zone)

Paper ID- AMA-08-06-2022-11450

African agriculture suffers from under-mechanization which results in the absorption of a large part of the active population for yields that do not take off despite all the programs put in place in the different countries. The low level of use of inputs and poorly adapted equipment are cited among the main constraints to the development of the sector. The labor productivity gap between manual agriculture and the most motorized agriculture in the world is today of the order of 1 to 2000 in gross productivity and 1 to 500 more in net productivity. Senegal has a long history of agricultural mechanization, both in terms of motorized equipment for the production and processing of products and in terms of animal traction. However, many attempts to introduce motorized agriculture have been made in sub-Saharan Africa. Many governmental and non-governmental projects have tried for many years and without much success to adapt motorized equipment on African family farms, while a number of countries have made agricultural mechanization a preferred means of transforming agrarian structures, which has also failed. In recent years, the Senegalese government has implemented a policy of supporting producers in the acquisition of agricultural equipment. Elements of this policy include tax exemption for agricultural equipment, and 40 percent state subsidies for the purchase of agricultural equipment. Analysis of the trajectory of farms in Senegal shows that animal traction is the most widely adopted technology. Motorized agricultural equipment is often acquired as part of support for the agricultural policies in place and is intended for large producers. Motorization mainly concerns rice cultivation in the irrigated areas of the Senegal River valley and the Anambé basin, followed by high value-added crops in the Niayes area.

Effect of emerging new generation fertilizers on yield attribute, yield and profitability of timely sown irrigated wheat (Triticum aestivum L.)

Paper ID- AMA-08-06-2022-11448

A field experiment was conducted during the rabi season of 2020-21 at Crop Research Centre Meerut, India. The experimental site was sandy clay loam in texture having soil pH 7.9, organic carbon 0.40%, and 216.0, 11.5, 250.0 kg/ha and 0.80 mg/kg available N, P2O5, K2O and Zn respectively. Novel nutrient sources with 12 treatments consisting of control, basal application of recommended 100% NPK (150:60:40) kg/ha, 75% NPK (112.5:45:30) kg/ha + NPK spray 18:18:18 (15 g/l) + NPK Consortia seed treatment (250 ml in 3 litre water 60/kg seed) + Bio-stimulant (625 ml/ha) + Nano N (4 ml/l) + Nano Zn (10 ml/l) in various combinations were attempted on wheat variety HD 2967 in RBD design with three replications. Treatment having 75% NPK + NPK Consortia + NPK spray + Bio-stimulant spray + Nano Zn spray was on par with 100% NPK with biostimulant/nano Zn and significant over RDF in yield and yield attribute. Respective net return 99.45 × 103 ₹ ha-1 Was also better with B:C ratio of 3.0 over RDF.

Weed prevalence, root nodulation and chickpea productivity influenced by weed management and crop residue mulch

Paper ID- AMA-07-06-2022-11445

Chickpea is a poor weed competitor, and significant yield reduction takes place in presence of weeds. There are limited weed management options available in chickpea. Therefore, we investigated the effect of weed management practices and mulches on weed prevalence, root nodulation and chickpea productivity at Research Farm of JNKVV, Jabalpur (MP), India. A field experiment was conducted on a split-plot and replicated thrice. The main plot was assigned to four weed management viz. pendimethalin 38.7% CS at 1 kg/ha as pre-plant incorporation (PPI), hand weeding at 30 days after sowing (DAS), hand hoeing at 30 DAS and unweeded check, and in subplots four crop residues mulch (CRM), wheat straw (WSM), paddy straw (PSM) and soybean haulm (SHM) each at 5 t/ha and bare land. Results revealed that Unweeded control recorded with maximum weed diversity and biomass followed by hand hoeing at 30 DAS. Imposition of hand weeding at 30 DAS was recorded with the least weeds with lesser weed biomass resulting in higher weed control efficiency (WCE) and better root nodulation, though it was comparable to pendimethalin at 1 kg/ha. Among placed CRM, PSM was recorded with less density, lower biomass with higher WCE and root nodulation which was comparable to WSM but was superior to bare land. Hand weeding at 30 DAS recorded with better yield attributes like pods/plant, seed/pod and seed index lead to higher seed yield (1667 kg/ha) and was at par with pendimethalin at 1 kg/ha. The lower yield attributes and yield was recorded with unweeded control. Among CRM, placement of PSM produced more pods and seeds/pod with a higher seed index resulting in higher seed yield (1554 kg/ha) over others. Thus, placement of PSM at 5 t/ha with one hand weeding at 30 DAS can be recommended for better weed control and higher seed yield in chickpea growing areas of a similar agro-ecosystem.

Genetic Parameters Studies in Segregating Population of Bread Wheat (Triticum aestivum L.)

Paper ID- AMA-06-06-2022-11440

The experiment of present investigation was conducted to evaluate the 50 wheat genotypes (segregating population lines) along with 5 checks in Augmented Block Design at Research Farm of Department of Genetics & Plant Breeding, School of Agriculture, Lovely Professional University, Phagwara, Punjab. The Analysis of variance for 50 genotypes (F4 segregating population) and 5 check varieties revealed that the treatments are highly significant for days to 50% heading, days to maturity, plant height, number of spikelets per ear, number of grains per spike, spike length. The phenotypic coefficient of variation was greater in magnitude than genotypic coefficient of variation for all the characters under study. High values for both the phenotypic and genotypic coefficient of variation were observed in number of productive tillers per plant. Very high heritability with high genetic advance was observed for characters such as number of tillers per plant, number of productive tillers per plant, 1000-grain weight, biological yield, harvest index.
