Finger millet production on more than 30% of world arable land is limited by P availability and more than 70% in the semi-arid and marginalized areas which covers most of the Sub-Saharan Africa. Phosphorus is one of the most important elements significantly affecting plant growth and metabolism. Three finger millet varieties (U-15, P-224 and Ikhulule) were evaluated under four P fertilizer levels (0, 12.5, 25 and 37.5 kg ha-1 P2O5) at the International Crops Research Institute for the Semi-Arid Tropics Station, Alupe and the Kenya Agricultural and Livestock Research Organization Station, Kakamega during the long and short rainy seasons of 2015 with the aim of determining their agromorphological response and trait associations. The on-station experiments were laid out in Randomized Complete Block Design in factorial arrangement with three replications. The statistical analysis of phosphorus levels and variety exhibited significant differences (P<0.05) to stand vigor, plant height, leaf blade length, number of leaves and lodging. The results revealed that application of 25 kg ha-1 P2O5 rate led to the tallest plants (65.0 cm), longest leaf blades (58.0 cm) and highest number of leaves per plant (16) at Alupe site while 37.5 kg ha-1 P2O5 rate eliciting the tallest plants (58.79 cm), longest leaf blades (51.44 cm) and highest number of leaves per plant (13) at Kakamega site. The highest rate led to the greatest vigor in both sites for both seasons while the control had the poorest vigor. Variety P-224 showed the highest lodging count with 32 out of 246 plants per experimental unit during the rainy season at Kakamega. The unit increase in grain yield was positively and significantly correlated with increased values of the harvest index (r=0.375), number of leaves (r=0.393) and plant height (r=0.431) but negatively and significantly correlated to the 1000-grain mass (r=-0.578) and lodging (r=-0.233). The best phosphorus treatment for most of the parameters was 25 kg ha-1 P2O5 at Alupe while maximum levels of the study parameters were realized under the 37.5 kg ha-1 P2O5 rate at Kakamega.

<p>Banjarbaru merupakan salah satu daerah di Kalimantan Selatan yang memiliki prospek yang baik sebagai daerah pengembangan komoditas krisan. Pertumbuhan tanaman krisan sangat dipengaruhi oleh beberapa faktor, misalnya media tanam, ketersediaan air dan hara, iklim mikro, suhu, kelembaban, serta intensitas cahaya matahari tertentu sehingga untuk memenuhi kebutuhan akan cahaya yang optimal maka perlakuan naungan diperlukan selama fase pertumbuhannya. Penelitian ini bertujuan mengetahui pengaruh persentase kerapatan pada naungan terhadap pertumbuhan setek krisan varietas Puspita Nusantara. Penelitian dilaksanakan pada Bulan November sampai Desember 2020, bertempat di Kebun Percobaan Jurusan Agroekoteknologi Fakultas Pertanian Universitas Lambung Mangkurat Banjarbaru. Metode yang digunakan pada penelitian yaitu Rancangan Acak Kelompok (RAK) dengan perlakuan kerapatan paranet, yaitu n1 (paranet dengan kerapatan 75%), n2 (paranet dengan kerapatan 100%), n3 (paranet dengan kerapatan 125%), dan n4 (paranet dengan kerapatan 150%), yang terdiri atas lima kelompok sehingga terdapat 20 satuan percobaan, dan setiap satuan percobaan terdapat lima unit tanaman. Hasil penelitian menunjukkan bahwa persentase naungan berpengaruh terhadap parameter jumlah daun, persentase setek hidup, dan tinggi tanaman yang tumbuh, tetapi tidak berpengaruh nyata pada saat awal muncul tunas. Perlakuan n2 berpengaruh paling baik terhadap persentase setek hidup (64%), jumlah daun (4,1 helai) serta tinggi tunas (4,26 cm).</p><p><strong>Keywords</strong></p><p>Krisan; Setek; Paranet; Iklim mikro</p><p><strong>Abstract </strong></p><p>Banjarbaru as one of the areas in South Kalimantan has good prospects as a chrysanthemum development area. The growth of chrysanthemums is strongly influenced by several factors, such as planting media, availability of water and nutrients, microclimate, temperature, humidity, and a certain intensity of sunlight, so to meet the need for optimal light, shade treatment is required during the growth phase. This study aims to determine the effect of the percentage density in the shade on the growth of chrysanthemum cuttings of the Puspita Nusantara variety. The research was carried out from November to December 2020, at the Experimental Garden of the Department of Agroecotechnology, Faculty of Agriculture, Universitas Lambung Mangkurat, Banjarbaru. The method used in this research is a Randomized Block Design (RBD) with the treatment of n1 (shading net with a density of 75%), n2 (shading net with a density of 100%), n3 (shading net with a density of 125%), and n4 (shading net with a density of 150%), which consisted of five groups so that there were 20 experimental units, and each experimental unit contained five plant units. The results showed that the percentage of shade affected the parameters of the number of leaves, the percentage of live cuttings, and plant height that grew, but had no significant effect on the initial emergence of shoots. The n2 treatment had the best effect on the percentage of live cuttings (64%), the number of leaves (4.1 strands), and shoots height (4.26 cm).</p><p> </p>

This study aimed to evaluate the growth characteristics of irrigated Vitória pineapple plants grown in semi-arid conditions and determine its developmental stages based on those characteristics. It was used a randomized block design with four replicates. The experimental treatments were: plant harvest at 270, 330, 390, 450, 510, 570, 690, 750, and 810 days after planting (DAP). The following variables were determined: plant height, stem diameter, D-leaf length, D-leaf fresh and dry mass, biomass production of plants and plant parts (organs), and vegetative biomass. Five phenological stages are proposed based on vegetative biomass production: < 20% biomass production (V1); 21-40% (V2); 41-60% (V3); 61-80% (V4); and > 80% (V5). The maximum growth rate for plant height, D-leaf length, and stem diameter was observed at the end of the phenological stage V1 (390-411 DAP), and at the end of stage V5 these plant traits had average values of 106, 82, and 7 cm, respectively. The maximum biomass accumulation rates were observed at stages V4 and V5, resulting in a final fruit yield and total fresh biomass of 72 t ha-1 and 326 t ha-1, respectively. Finally, we estimated that 80% of the accumulated biomass may remain in the field after fruit and slip harvest, and could be incorporated as plant residue into the soil.

Saline irrigation water is becoming an important water source as fresh water is fast becoming a scarce resource in many areas of the world, including Eswatini, especially in arid and semi-arid regions.  A study to test the response of two varieties of spinach (fordhook giant and mustard) to salinity was conducted in a field pot experiment at the Faculty of Agriculture at the Luyengo Campus of the University of Eswatini.  The treatments were laid in a randomized block design (RCBD).  The experiment consisted of four treatments, each replicated twelve times.  Treatments were salinity levels of 0.0 dS/m, 1.5 dS/m, 2.0 dS/m and 3.5 dS/m.  All the treatments were subjected to similar agronomic practices. Spinach was grown and observed for a period of five weeks.  Plant height was measured and the number of leaves counted weekly throughout the experiment. Significant differences (P < 0.05) between salinity treatments were obtained for plant height beginning in week 2 but were more pronounced in week 3, 4 and week 5.  No significant differences were obtained for the number of leaves.  There were however, clear significant differences between spinach irrigated with none saline irrigation water compared to saline irrigation water.   It was concluded that irrigating spinach with saline water of more than 2.0 dS/m drastically reduce plant growth but not the number of leaves under the conditions of the experiment.

Pest attacks on chili plants are the main limiting factor in cultivation activities. The research  aims to determine the effect of single application of botanical pesticide maja-gadung (PMG), single application of secondary metabolite Beauveria bassiana BIO (BIO B10), combined application of PMG and BIO B10  on pest populations, predator populations and plant growth and production of  chili. The  reesearh used a factorial Completely Randomized Block Design (RAKL) with 3 replications, so there were 9 treatment combinations (0 ml/l PMG, 4 ml/l PMG, 8 ml/l BIO B10, 0 ml/l PMG, 2  ml/l BIO B10,  4 ml/l BIO B10, 4 ml PMG+2 ml/l BIO B10,  4 ml/ml PMG+4 ml BIO B10, 8 ml/l  PMG+2ml/l BIO B10, 8 ml/l PMG+4 ml/l BIO B10). The variables observed were Thrips sp population, predator population, plant height, number of leaves, and fruit weight per plant. The results showed that the single application treatment of PMG  with a concentration of 4 ml/l and 8 ml/l was able to suppress the population of Thrips sp. by 21.6% and 41.4% compared to the control. The single application treatment of BIO B10  with concentrations of 2 ml/l and 4 ml/l was able to suppress the population of Thrips sp. by 66.5% and 65.5% compared to the control. The best combination application is PMG  and BIO B10with a concentration of 8 ml/l + 4 ml/l which is able to suppress the population of Thrips sp. by 76.9% compared to the control. The application treatment of PMG andBIO B10 did not affect plant height, number of leaves, and fruit weight per plant.

In sub-Saharan Africa, multiple plant nutrients deficiency besides nitrogen (N) and phosphorus (P) is a major growth-limiting factor for crop production. As a result, some soils become non-responsive for Rhizobium inoculation besides P application. Based on the soil test result, the soil of Experimental sites had low organic matter (OM), nitrogen (N), phosphorus (P), sulphur (S) and zinc (Zn)[xy1]. Hence, an experiment was carried out on-farm at Gondar Zuria woreda in Tsion and Denzaz Kebeles to evaluate the effect of Rhizobium inoculation, S and Zn application on yield, nodulation, N and P uptake of chickpea. The experiment included twelve treatments developed via factorial combination of two level of inoculation (Rhizobium inoculated, un-inoculated), three level of S (0, 15, 30 kg Sulphur ha-1) and two levels of Zn (0, 1.5 kg Zinc ha-1). The treatment was laid out in randomized complete block design with three replications. Results showed that the highest mean nodule number (15.3) and nodule volume (1.3 ml plant-1) over locations were obtained with Rhizobium inoculation integrated with 15 kg S and 1.5 kg Zn ha-1 which resulted in 37.8% and 116.7% increment over the control check, respectively. It was also observed that combined application of Rhizobium and 30 kg S ha-1 caused the highest (6.7) mean nodulation rating and seed yield (1775.5 kg ha-1) over locations which resulted in 86.1% and 28 % increase over the control check, respectively. Moreover, this treatment improved P use efficiency of chickpea. On the bases of observed result, it can be concluded that the response of chickpea to Rhizobium and P application can be improved by S application and Rhizobium inoculation with application of 30 kg S ha-1 with recommended rate of P and starter N is recommended for chickpea production at the experimental locations in Gonder Zuria Woreda.

Field trials were carried out during 2018 and during 2019 dry season periods at Federal College of Forestry and Mechanization Afaka Kaduna, located between latitude 10° 35”N and longitude 007° 21”E at altitude 644 m above sea level, to determine the effects of organic manure source and weeding frequencies on growth parameters of jute mallow (Corchorus olitorious). The experimental treatments consists of ten combinations of poultry manure + weed free, cow dung + weed free, goat dropping + weed free, poultry manure + weeding at 2 WAT, cow dung + weeding at 2 WAT, goat dropping + weeding at 2 WAT, poultry manure + weeding at 4 WAT, cow dung + weeding at 4 WAT, goat dropping + weeding at 4 WAT and  no organic manure application + no weeding which were laid out in a randomize complete block design (RCBD) and replicated 3 times The growth parameters observed  and measured were crop vigour score, plant height, shoot diameter, number of leaves and number of  primary branches. Result of the study showed that at harvest (8 WAT) all the treatments significantly affected the vigour of jute mallow crop and gave comparable score than the least observed with no nutrient + no weeding as control. The result revealed that plant growth at harvest exhibited significantly taller plant with application of poultry manure + weeding at 2 WAT. In conclusion the result obtained from the study showed that poultry manure at 4 tons /ha + weeding at 4 WAT resulted in taller plant height, wider shoot diameter, increased number of leaves, number of branches than all other treatment due to lower weed infestation, it is therefore recommended as the best treatment combination to obtained the best growth rate of jute mallow.

This article proposes a strategy for agricultural technology development for semi-arid West Africa. The strategy evaluation consists of two aspects: a) a review of the successes in the region; and b) analysis with mathematical programming of the potential impacts and constraints to various new technologies tested in the region. The technology development strategy indicates how further productivity gains can be made by responding to the two principal constraints of water availability and soil fertility. These constraints must be simultaneously resolved but the strategy needs to be adapted for different soil characteristics and economic environments. The major emphasis is on the importance of the rapid introduction of inorganic fertilizers combined with techniques to increase water availability; organic and inorganic fertilizers need to be considered complements in the semi-arid regions. Farmers are already introducing labour intensive variations of these techniques in the most degraded regions. The policy concern is to encourage government policymakers to put a high priority on fertilizer and increase the availability of inorganic fertilizer while research efforts continue to develop improved methods for complementary use of organic fertilizer.
