“…Other factors such as radiation quality, sunlight interception and day length may be responsible for the variation observed in leaf area and leaf area index between the two locations 25 . Pigeon pea accessions grown in Calabar showed a higher mean relative growth rate than those in Obudu which may be attributed to the duration to maturity of the accessions and the overall supply of light, water, temperature and nutrient availability 26 .…”

Background and Objective: Sustainable food security in Nigeria has become very important to curb malnutrition and protein deficiency. Changes in the observed climate are affecting the growth of food crops through phenological alterations among other stress factors. Pigeon pea (Cajanus cajan (L.) Millsp.) has been reported as one of those crops with significant potential to withstand these stressors as well as meet the demands for a source of protein and medicine for humans and livestock. This study assessed the growth parameters of fifty accessions of pigeon pea (Cajanus cajan (L.) Millsp.) cultivated in two ecological zones in Cross River State.Materials and Methods: A 50×2 factorial in a completely randomized block design with three replications was used. Three seeds per accession were sown per hole at a depth of 2 cm and thinned to two after emergence, on beds measuring 1×1 m. Each bed had six plants and growth parameters were measured on plant height, number of leaves, number of branches and leaf area. Results: It showed significant differences in growth parameters, including plant height, number of leaves, number of branches, leaf area, leaf area index and relative growth rate between the two locations, with the accessions planted in Calabar displaying higher mean values for all parameters except plant height and leaf area indices, 50.98 and 5.38 cm, respectively, which were higher in Obudu. Conclusion: The findings of this study showed that these fifty accessions of pigeon peas can be cultivated successfully in Calabar and Obudu. This information is crucial for farmers to optimize pigeon pea production to diversify the food base, ameliorate protein deficiency and enhance soil nutrition in Cross River State and Nigeria.

The trail was conducted at Field Experimentation Centre, Department of Genetics and Plant Breeding,NainiAgricultural Institute, SHUATS, Prayagraj during Kharif 2019-2021. The experiment was carried out with17 genotypes (16+1 check variety) of pigeonpea, which were obtained from IIPR, Kanpur (U.P) inRandomized Block Design (RBD) with 3 replications for growth and yield attributes. Observations weremade on five plants that were randomly selected for eleven growth and yield traits except field emergence,days until 50 percent flowering and days to maturity, where the observations were noted on a plot basis.Among the genotypes G13 recorded early days to maturity (252.17), maximum plantâs height (268.70 cm),highest emergence on field (84.67%), more No. of branches/plant (29.67), No. of pods/plant (206.90), No.of seeds/plant (397.93), maximum seed yield/plant (57.00 g.), seed yield/plot (6.45 kg.), 100 seedsweight(15.16 g.) and seed yield q/ha (24.90 q.), while genotype G12 noted less days to 50% flowering (173.83). G-13 and G-7 genotypes taken most down days for flowering and maturity and good yield in comparison tothe check variety (MAL-13). Along with many genotypes G-13 was determined to be the most promisingand should be considered for commercial cultivation under the agro-climatic conditions of Prayagraj.

“…Its yield is affected by various biotic and abiotic factors ranging from moisture, altitude, temperature, photoperiodism, insect pests, mineral stresses, diseases, and a lack of varieties with broad adaptability to a range of environments [16,17]. In India, crop yield was reported to be 652 kg ha -1 , 1,268 kg ha -1 in Malawi, 921 kg ha -1 in Myanmar, 300-400 kg ha -1 in Mozambique, and 1,345 kg ha -1 in the guinea savanna of Nigeria, while global productivity is at 774 kg ha -1 [4,18,19]. To mitigate against this gap in pigeon pea yield, varieties that are resistant to abiotic and biotic stresses need to be developed [20].…”

Pigeon pea [Canjanus cajan (L.) Millsp.] is an orphan crop that has remained greatly unimproved in quality and quantity in Africa even though it has great potential of supplying food to the growing population. Its yield is affected by various biotic and abiotic factors and a lack of varieties with broad adaptability to a range of environments. It is therefore important to select accessions that are stable in different environments for yield and yield components. A randomized complete block design layout was used to carry out a multi-locational trial using 107 pigeon pea accessions. Data was taken for the total number of pods per plant at maturity, pod length, seed weight, seeds per pod, and seed yield per plant. Additive main effects and multiplicative interaction (AMMI) with genotype and genotype by environment interaction (GGE) biplot were used to interpret the data. The mean squares for the PCA explained by the first two principal components account for 100% of the G x E interaction. The results revealed that the differences in the yield and yield components across the three locations were mostly due to the genotypes of the pigeon pea and to some extent the genotype by environment interaction. Six accessions were observed to be high-yielding and stable across all three environments.
