The field experiment was conducted in the season of 2017-2018 at the Agricultural Research Department-AL-Azafrinih/Baghdad-Iraq. This study aimed to determine the effect of adding the Foliar Fe fertilization (Nano-Fe) and ground fertilization of (N, P) in the growth and production yield of rapes (Brassica napus L.). The experiment included three levels of foliar fertilization (Nano-Fe) that is (0, 5, 10 Kg. ha-1) and one level of ground fertilization (N 100 Kg. ha-1, P 250 Kg. ha-1). The experiment designed according to Randomized Complete Block Design (R.C.B.D) with three replications each parameter. The studied traits were nutrients content (macro-micro) in seeds and soil, the percentage of protein, oil, and carbohydrate. All data were analyzed and used statistically. Results showed a significant difference between Nano-Fe fertilization and nutrient content (N, Mn, K, Ca, Mg, S, and Cu), pH in soil at the level of 10 kg. ha-1, compared to no-fertilization. Moreover, the significant difference between Nano-Fe fertilization, yield (1425.6 kg. ha-1), the percentage of oil (52.16%), protein content in seeds (46.5%), carbohydrate (26.8%), Nutrient content N and P in seeds at the level of 10 kg. ha-1, compared to no-fertilization and the nutrient content (Ca, Mg, Fe) in seeds at levelof5 kg. ha-1, compared to no-fertilization. Current results suggested that Nano-Fe fertilization at the level of 10 kg. ha-1 can be adopted as the best level for rapes (Brassica napus L.) cultivation under semi-arid conditions.

ABSTRACT Intercropping systems of beet and green cowpea are beginning to be implemented in the northeastern semi-arid region in Brazil. The great challenge is to know if there is agro-economic efficiency in these systems when fertilized with organic matter produced by spontaneous species of the Caatinga biome. Thus, the objective of this research was to evaluate the effect of green manuring using different amounts of hairy woodrose (Merremia aegyptia) in the association of beet with green cowpea under the semi-arid conditions. The experiment was carried out at the Rafael Fernandes Experimental Farm, rural area of Mossoró, RN, Brazil, in the period of September-December 2015, in a randomized complete block design with four treatments and five replicates. The treatments consisted of hairy woodrose amounts incorporated into the soil (10, 25, 40, 55 t ha-1 on a dry basis). The cultivars of beet and green cowpea planted were ‘Early Wonder’ and ‘BRS Itaim’, recommended for the semi-arid conditions of the Brazilian Northeast. The best agro-economic performance for intercropping system of beet and green cowpea was obtained with 55 t ha-1 of hairy woodrose incorporated in the soil. The use of the hairy woodrose species as green manure is agronomically viable in intercropped systems with beet and green cowpea.

Rapeseed (Brassica napus L.) is the best one in respect of oil production. It is the order of the day to take better steps for production and quality improvement of our local cultivars. Broadening of genetic diversity in spring oilseed Brassica napus L. (AACC, 2n = 38), canola is important for continued improvement of this crop. Sixty-two genotypes in F4 generation of Brassica napus L. were evaluated to assess genetic diversity based on randomized complete block design with three replications at the experimental field of Sher-e-Bangla Agricultural University, Dhaka. Different Multivariate analyses were performed to classify 62 genotypes. On the basis of cluster analysis, all the genotypes were classified in five clusters. The cluster IV comprised the maximum number (19) of genotypes followed by same in cluster II (18). The cluster I and V comprised 10 and 9 genotypes respectively. The lowest number of genotypes was present in cluster II. The highest inter-cluster distance (10.309) was observed between the cluster I and IV and the genotypes of these clusters involved in hybridization may produce a wide spectrum of segregating population. The lowest inter-cluster distance (3.513) was observed between the cluster III and IV. The inter-cluster distances were larger than the intra-cluster distances. Considering cluster distance, inter genotypic distance and other agronomic performance G3, G4, G24, G35 and G51 might be suggested for future breeding program. SAARC J. Agric., 19(1): 15-25 (2021)

RESUMO - Avaliou-se comportamento da rebrota de cultivares do sorgo sacarino e forrageiro no semiárido potiguar sob diferentes lâminas de irrigação. O ensaio foi realizado em março de 2015, nas condições de campo, em um argissolo no município de Upanema-RN, região Nordeste do Brasil. O experimento foi conduzido com delineamento experimental em blocos casualizados completos, em esquema de parcelas subdivididas 4 x (5 x 2), com quatro repetições, sendo quatro lâminas de irrigação (50, 75, 100 e 125% da ETc), e cinco cultivares (duas cultivares sacarinas, BRS 506 e BRS 511, e três forrageiras IPA 467-4-2, IPA SF-15 e BRS Ponta Negra) combinadas com duas densidade de plantio nas subparcelas. As variáveis avaliadas foram as produtividades de massa fresca e seca. Verificou-se que a lâmina de irrigação repondo 100% da ETc proporcionou maior rendimento de biomassa e que as cultivares sacarinas apresentaram baixa capacidade de rebrota, sendo as variedades IPA SF 15, IPA 467-4-2 e a BRS Ponta Negra as mais produtivas.Palavras-chave: Sorghum bicolor, semiárido, estresse hídrico. GROWTH AND PRODUCTION OF THE FIRST REGROWTH OF SORGO CULTIVARS UNDER DIFFERENT IRRIGATION BLADES  ABSTRACT - Behavior of re-growth of saccharin sorghum and forage sorghum cultivars in the semi-arid region of the State of Rio Grande do Norte (RN), Brazil, under different irrigation blades was evaluated. The experiment was carried out in March 2015 under field conditions in an argisol in the municipality of Upanema-RN, northeast region of Brazil. The experiment was carried out in a complete randomized complete block design with four replications (4 x 5 x 2), four irrigation blades (50, 75, 100 and 125% of ETc estimated from climatic data of Mossoró-RN) and five cultivars (two saccharin cultivars, BRS 506 and BRS 511, and three forage cultivars, IPA 467-4-2, IPA SF-15 and BRS Ponta Negra) combined with two planting densities in the subplots. Fresh and dry mass productivities were evaluated. The results were submitted to analysis of variance (F test) and the means were compared by the Tukey test at the 5% probability level, using the SAEG 8.1 software. It was verified that the irrigation blade replacing 100% of the ETc provided a higher yield of biomass and that the saccharin cultivars presented a low sprout capacity, with the varieties IPA SF 15, IPA 467-4-2 and BRS Ponta Negra being the most productive. Keywords: Sorghum bicolor, semiarid, water stress.

To evaluate the effect of irrigation (irrigation disruption at beginning of flowering, end of flowering, grain filling and control) and biological phosphorus (0, 50, 100 and 150 g/ha) on the yield of Brassica napus L. cv. ‘Hyola 401’, a split plot experiment was carried out based on randomized complete block design with four replications in 2010. The maximum (4.55 g) and minimum (3.25 g) 1000 seed weight belonged to irrigation disruption at the beginning of flowering with 150 and 50 g/ha of biological phosphorus application, respectively. The highest yield of seed (777.58 kg/ha) was obtained from irrigation disruption at the end of flowering with 50 g/ha biological phosphorus, and the lowest yield of seed (120.87 kg/ha) was obtained from irrigation disruption at the beginning of flowering without biological phosphorus. The maximum number of complete pods (17.38) was observed in 150 g/ha of biological phosphorus application by normal irrigation, and the lowest number of complete pods (5.49) belonged to no phosphorus application with irrigation disruption at the beginning of flowering stage. The highest percent of infertile pods (55.29%) was obtained from no phosphorus application with irrigation disruption at the beginning of flowering. And the lowest infertile pod percent (20.67%) belonged to 150 g/ha biological phosphorus application at normal irrigation.

Sugarcane quality for industry directly depends on irrigation, especially in semi-arid regions. This study aimed to evaluate the technological performance for industry of six sugarcane varieties at five irrigation depths. Sugar-cane Brix and Pol%, juice Brix and Pol%, fiber, purity, reducing sugars and total sugars were evaluated 11 months after planting. The experiment was conducted in Brazil, in the semi-arid region of Minas Gerais state. The experiment was arranged in a randomized block design, in a subdivided parcel scheme (6 x 5) and four repetitions. Different irrigation depths did not affected Brix. The cultivar RB83-5486 presented the highest value for juice Pol%, among the evaluated varieties. Juice Pol% and sugar-cane Pol% presented similar behavior, and displayed the highest values at the 1081 mm irrigation depth. In general, the analyzed varieties presented low fiber content. All the analyzed varieties surpassed 80% purity. The highest irrigation depths enhanced purity. The highest value was obtained at the 1081 mm depth. Decreased reducing sugars and increased total reducing sugars were observed at the highest depths and the highest accumulation was found at the 1081 mm depth. As conclusion for industrial characteristics, the irrigation presented potential to enhance the technological performance of sugarcane in semi-arid conditions. Considering the technological performance for industry, the cultivar RB83-5486 has good potential to be used under the studied conditions. When higher levels of fiber and reduced sugars are desired, lower irrigation depths are recommended.

Green gram (Vigna radiata (L.) wilczek,) commonly known as moong or mung bean or golden gram was introduced to Eritrea as a pulse crop by Ministry of Agriculture at its National Agricultural Research Institute (NARI) in collaboration with Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA) in 2012. But its agronomic practices for semi-arid conditions of Eritrea are not yet standardised. Therefore , to find the optimum inter row spacing and phosphorus dose for its higher productivity ,a field experiment was conducted at the experimental farm of Hamelmalo Agricultural College, Keren, Eritrea during summer 2015 and 2016. The experiment was conducted in randomised complete block design (RCBD) with 12 treatment combinations of two factors consisting of four inter row spacing (Broadcast, 18cm, 30cm, and 45cm) and three phosphorus levels (0, 20 and 40 kg P2O5 ha-1) each replicated thrice. The results of the study revealed that sowing of K-26 bold seeded variety either by broadcast method or at 18cm inter row spacing at10cm plant to plant spacing fertilized with 40kg P2O5 ha-1 through DAP fertilizer drilled at the time of sowing proved significantly superior to increase growth, yield attributes and seed yield of green gram.
