Drought affects the rainfed groundnut (Arachis hypogaea L.)  at different phases of development and it is the serious threats on groundnut productivity causing losses than any other abiotic factor under rainfed agriculture. In the world's semiarid regions, groundnut accounts for 90% of worldwide production. Drought mainly affects the pace and pattern of nutrient and water intake from the soil, affecting the architecture of the groundnut root system. Plant selections with desirable root trait have been a major focus in developing drought resistant Groundnut cultivars. In 2019, 60 groundnut genotypes were cultivated in root block design with two different soil water treatments, as well as in the field during the year under same circumstances. The purpose of this study was to see how different groundnut cultivars fared in terms of yield, yield contributing features, root characters, and their relationships with drought tolerance. Drought resistant genotypes had thicker roots, larger roots, and a deeper root system than susceptible genotypes. Recent series in groundnut genotypes of 60 numbers were sown during kharif 2019 (july-september) under rainfed condition (It includes life irrigation and rainfall received during cropping season). Groundnut genotypes were semi spreading with the duration of 110-120 days. Observation on root morphological character viz., roots length, root volume after 20 days of stress imposition of the crop and yield parameters were observed at the harvest. Among the 60 genotypes, 20 genotypes (VG 17008, VG 17046, VG 18005, VG 18102, VG 18077, VG 19572, VG 19709, VG 18111, VG19561, VG19576, VG 19620, VG 19681, VG 19688 etc.,) similarly, yield character were observed for 60 genotypes and all the genotypes given above recorded higher value in Total number of pods per plant, Number of double seeded pods per plant, Pod yield per plant, Harvest index and Total dry matter production. The methods used in this study identified correlation between yield character and root characters. Groundnut genotypes by assessing yield metrics and their relationship with root trait. These findings lay the groundwork for future study aimed at deciphering the molecular pathways underpinning Groundnut drought resistance.

Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 41-49.The purpose of this study was to evaluate the application effects of three different compound fertilizers on yield, and assess the income increase at different rates of compound fertilizers. Three compound fertilizers namely NPK 14-0-46, NPK 19-9-19 and NPK 11-11-11 was conducted at three different farmers’ field in Langkat District, North Sumatra Province under upland conditions. In each farmers’ field, a Randomized Complete Block Design was applied with four replications per treatment.  Seven treatments tested consisted of full rate of farmer fertilizer practice and six rates of each compound fertilizer plus half rate of farmer fertilizer practice. In each of compound fertilizer tested, pod yield and seed yield increased quadratically as increasing compound fertilizer rates. The highest pod yield and seed yield of peanut were 1649 kg/ha and 1072 kg/ha, respectively with half rate of FFP + 200 kg of NPK 14-0-46. For compound fertilizer NPK 19-9-19 the highest pod yield and seed yield were 1632 kg/ha and 1032 kg/ha with half rate of FFP + 500 kg of NPK 19-9-19 while for compound fertilizer NPK 11-11-11 the highest pod yield seed yield were 1421 kg/ha and 930 kg/ha with half rate of FFP + 250 kg of NPK 11-11-11. However, adding each  half rate of farmer fertilizer practices with  200 kg of NPK 14-0-46 or 300 kg of NPK 19-9-19 or 250 kg of NPK 11-11-11 with HypoMa-1 cultivar gave the highest values of the benefit for the farmers under upland soil in Langkat, North Sumatra.

Background: Peanut (Arachis hypogaea L.) is one of the oil and cash crops in Vietnam. However, owing to the lack of appropriate management practices, the production and the area under cultivation of peanut have remained low. Mulches are the key factors contributing to promoting crop development and early harvest and increasing yields. Methods: The experiment consisted of three mulch treatments, viz., plastic mulch, straw mulch and no-mulch control. All the treatments were replicated thrice in a complete randomized block design. Result: In the conditions of mulch, the plant growth parameters (germination rate, growing time, plant height, number of branches per plant), leaf area index, the number of nodules per plant, dry matter accumulation, yield components and yield of peanut was much higher than that of no-mulch control. Among the mulches, plastic mulch was found superior to straw mulch in the pod yields and water-use efficiency and moisture conservation, thereby can be considered as a reliable practice for increasing the productivity of peanut on the coastal sandy land in Nghe An province, Vietnam.

Comprising 34 groundnut genotypes an experiment was conducted in a randomized block design with three replication at the Research farm of Regional Agricultural Research Station, BARI, Hathazari, Chittagong during Rabi season (December 2009 to April 2010) for estimation of the multivariate analysis of divergence. The genotypes were grouped into five clusters. Cluster III contained the highest number of genotypes (12) and the cluster II contained the lowest (2). The inter-cluster distances in all cases were larger than the intra-cluster distance which indicated that wider diversity is present among the genotypes of distant grouped. The highest intra cluster distance was observed in cluster V and the lowest in II. The highest inter cluster distance was observed between the cluster IV and III followed by V and III and the lowest between cluster V and I. Days to 50% flowering, days to maturity, number of branches per plant, number of matured nuts per plant and karnel size were the most important contributors based on the latent vector. But the highest cluster means for matured nuts per plant, 100 karnel weight, 100 nuts weight and yield per plant were obtained from the cluster II. With moderate yield but early maturity varieties were found in cluster IV. Therefore, more emphasis should be given on cluster VI for selecting genotypes as parents for crossing with the genotypes of cluster II and III for getting new recombinants with early maturity and higher yield.   Key Words: Genetic divergence; cluster analysis; D2 analysis; groundnut (Arachis hypogaea L) DOI: http://dx.doi.org/10.3329/bjpbg.v23i1.9317 BJPBG 2010; 23(1): 45-49
