The experiment was conducted at Haro Sabu Agricultural Research Center, Western Oromia for two consecutive years, with the objective to identify adaptive, high yielding and disease/pest resistance varieties. Seven varieties were grown as experimental treatments in a randomized complete block design (RBCD) with three replications. Analysis revealed that DZ-96 and DZ-123 had maximum percentage of survival rate at one year age 0092 and 0347completely died obtained from in one and two years age.  Days of 50% flowering showed statistically highly significant and Mean performance of plant height trait at different ages and seed yield were also significant (p<0.05). Mean green forage yield and Dry matter yield was not significantly (p<0.05) among treatments. But numerically difference was observed among treatments. Maximum fresh weight and sun-dried dry matter yield (DMY) were 84.43 t ha-1 & 27.64 t ha-1 recorded from DZ- 96 followed by DZ-89 and DZ-123 with 18.91 & 18.36 ton ha-1 of sun dried DMY respectively. The best average seed yielders among the tested varieties were recorded from DZ-96 with 47.25 q ha-1 followed by DZ-89 with 46.84 q ha-1. It is concluded that DZ- 96 and DZ- 89 were better performance varieties which are suitable for use as animal feeds.

Abstract Background Understanding the relationship between dry matter yield production and forage quality throughout the growing season will help to optimize the cutting intervals between harvests in different Alfalfa (Medicago sativa L.) varieties. An experiment was conducted to assess the effects of harvest frequency on forage yield and quality of 2 improved cultivars (ILRI-6984 and var. DzF-552) of alfalfa (Medicago sativa L.) in Western Dembia district over 20 months during 2017 and 2018. Four harvest frequencies (every 30, 40, 50 and 60 days) were compared in a randomized complete block design (RCBD) with 4 replications. The experiment was laid down in a randomized complete block design (RCBD) in factorial arrangement with four replications. To assess their production potential plant height (cm), number of branches per plant, fresh biomass yield (t ha−1) and dry matter yield (t ha−1) of the forge and its nutrient content were recorded. The data collected was subjected to analysis of variance (ANOVA) by using the general linear model (GLM) procedure in Statistical Analysis System (SAS) (2003) version 9.1. Results The results revealed that highest forage dry matter yield was recorded for variety ILRI-6984 harvested every 40 days (26.8 t DM ha−1) and for var. DzF-552 when harvested every 60 days (24.1 t DM ha−1) (P<0.001). While crude protein concentration tended to decline as age at harvest increased, there was little consistency in the pattern. Crude protein yields were also inconsistent across treatments but ILRI-6984 harvested every 40 days produced the highest yields (6.5 t ha−1) (P<0.001). Conclusion These preliminary findings need to be confirmed under field conditions on a large scale along with longer-term studies to examine the longevity of the stands at these harvest frequencies. Irregular harvesting based on stage of maturity should be compared with fixed inter-harvest intervals.

Field experiment was carried out during the spring and fall seasons of 2019 at the Abu Ghraib Research Station of the Agricultural Research Office/ Ministry of Agriculture, was aimed to investigate the effect of plant growth inhibitors on growth and yield of several sorghum varieties .Randomized Complete Block Design within split plot arrangement with three replications was used. The main plot consists of three growth inhibitors (Cycocel, Ethiphon, and Mebiquat), which were added at stages six and eight leaf stage, in addition to the control treatment (distilled water only), the sub plot was included three cultivars (Mabrouk, Buhooth 70 and Giza 113). The results showed in both seasons significant interaction between cultivars and growth inhibitors in most of the studied traits. The plants of the variety Giza 113 sprayed with Ethiphon recorded the lowest period of reaching physiological maturity, the highest average dry matter yield, and the highest weight of 1000 grains (89.00 days, 17.32 ton ha-1, and 39.33 gm) respectively. The same variety recorded the highest content of chlorophyll in the leaves and the highest grain yield due to the effect of Mebiquat (49.50 spad, 3.93 ton ha-1. The cultivar Buhooth 70 with the effect of Cycocel achieved the highest average of dry matter yield of 33.27 ton ha-1.

An experiment was conducted to evaluate the effect of growth, biomas yieds and nutritive value of Lablab purpureus, Centrosema pubescens and Mucuna pruriens under rain fed condition in Yola, Adamawa State, Nigeria. The field experiment was laid in a randomized complete block design with the plot divided into three main plots and replicated three times measuring 5x5m with inter and intra row spacings of 0.5m. The five harvesting stages are 6, 8, 10, 12 and 14 weeks, respectively. The growth in height increases with stage of growth and declined with reduction in rainfall. Higher growth were recorded in T3 (3.8 -354.8cm) followed by T2 (2.96-260.20cm) and then T1 (1.50-213.00cm) and the results were presented graphically. The result of the chemical composition of all the legumes showed that the crude protein decreases with stage of growth from weeks 6 -14 (14.40, 12.26, 10.65-10.08, 6.79, 6.49) and ADF and NDF (25.20, 32.15, 27.35-42.13, 40.33, 36.50 and 32.20, 54.45, 47.00- 51.24, 63.53, 66.33), respectively. The biomass yields were significantly different (P<0.05) for all the legumes at different harvesting stages T1 (2744.53-3186.93), T2 (2696.47- 3006.70) and T3 (2843.73-3147.63). It is therefore concluded that legumes could best be harvested between weeks 10 and 12 when the yield and quality are at levels to sustain the animals both for maintenance and production.

Strip Intercropping

In traditional row and strip cowpea-sorghum intercropping systems, cowpea forage yield reduces significantly due to intense competition and dominance of sorghum in acquiring growth resources. This field study evaluated novel mixed strip intercropping systems of forage cowpea and sorghum having different number of crops rows arranged under different spatial arrangements. Cowpea was intercropped with sorghum in 8, 12 and 16 rows strips with row-row spacing of 30, 45 and 60 cm. In each strip, equal number of rows of cowpea and sorghum were maintained. Factorial arrangement of randomized complete block design with three replicates was used to execute the field trials during summer seasons of 2013 and 2014. Strips having 12 rows and 60 cm row-row spacing positively affected all agronomic variables of cowpea which led to maximum forage yield (22.2 and 23.7 t ha-1 during 2013 and 2014 respectively) and dry matter biomass (6.63 and 6.94 t ha-1 during 2013 and 2014 respectively). In contrast, 8-rows strips having line spacing of 30 cm outperformed other intercropping systems by yielding the maximum herbage yield and dry matter biomass of sorghum. The intercropping system comprising of 12-rows strips with 60 cm row-row spacing remained superior in recording the maximum crude protein, fats and total ash along with the minimum fiber content of cowpea. In addition, this intercropping system under rest of spatial arrangements also remained unmatched, while 16-rows strips under all planting geometries remained inferior to other intercropping systems. Thus, cowpea intercropping with sorghum in 12-rows strips having 60 cm spacing offers biologically viable solution to improve biomass and forage quality of cowpea in intercropping with sorghum.

The expansion of sugarcane cultivation, especially in areas with low natural soil fertility, such as savannah regions, requires greater efficiency in the application of nutrients, mainly nitrogen (N). The objectives of this study were to evaluate the effects of the application of different sources and doses of nitrogen on the dry matter yield and productivity of sugarcane in the plant cane cycle and the residual effect of such application on the first ratoon cycle of sugarcane (var. SP80-1816) cultivated in a dystrophic Red Oxisol. The experimental design was a randomized complete block design analyzed in a factorial scheme of 2 × 4 with three replications. The evaluated factors consisted of two sources of N (ammonium nitrate (AN) and urea (U)) and four doses of N (0, 60, 120 and 180 kg ha-1). Samples of the aerial part of the sugarcane were collected. The structural components of the aerial part were separated, and the leaf dry matter (LDM), stalk dry matter (SDM) and dry matter of the aerial part (DMAP) were analyzed. The productivity of stalks (PS) was determined by weighing all stalks present in the useful area of each plot. In the plant cane cycle, AN resulted in greater gains in the SDM and PS of sugarcane than did U. In the first ratoon cycle, a residual effect was observed in response to N application, which showed an increase in SDM and PS. Under the conditions of this study, to achieve a higher PS in both cycles, the application of 180 kg N ha-1 is recommended

This experiment was conducted to determine the effects of mixture rates of hairy vetch with oat, barley and wheat on dry matter yield and its quality and to determine the suitable mixture when grown as catch crop at Uludag University, Faculty of Agriculture, Agricultural Research and Application Center, Bursa Turkey during 2011-2012 and 2012-2013 growing seasons. The experimental plant entries were Menemen-79 variety of hairy vetch, Faikbey cultivar of oat, Akhisar-98 cultivar of barley and Flamura cultivar of wheat. Nine mixtures (25 % oat:75 % hairy vetch, 50 % oat:50 % hairy vetch, 75 % oat:25 % hairy vetch, 25 % barley:75 % hairy vetch, 50 % barley:50 % hairy vetch, 75 % barley:25 % hairy vetch, 25 % wheat:75 % hairy vetch, 50 % wheat:50 % hairy vetch, 75 % wheat:25 % hairy vetch) were used. Several parameters such as dry matter yield, leaf area index, light interception, crude protein content and yield; ADF (acid detergent fiber) and NDF (neutral detergent fiber) contents and relative feed value have been examined in the experiment. The highest dry matter yield was obtained from the mixtures of 50 % oat:50 % hairy vetch (12 040 kg ha-1) and 75 % oat:25 % hairy vetch (11 748 kg ha-1). According to the two-year results, the higher and quality hay yield (low in ADF and NDF values, high in relative feed value) was produced at 50 % oat:50 % hairy vetch mixture, and this mixture have been proposed to the experimental conditions due to its suitability.

The low nutrients levels available in pasture formation reduces the forage yield. Soil correction and fertilization practices are considered priorities in the planning, renovation or recovery of pastures. The aimed of this experiment was to evaluate the effect of nitrogen and phosphate fertilization rate in productivity of the Panicum maximum cv. BRS Zuri. The experimental design was a randomized block design in a 3×4 factorial arrangement, with three doses of superphosphate (0.0, 80.0 and 160.0 kg.ha-1) and four doses of ammonium nitrate (0.0; 20.0; 40.0 and 60.0 kg.ha-1), with three replicates. The following parameters were evaluated at 120 days after implantation: green mass and dry matter yield, plant height, number of plants and tillers per square meter. The doses of 80.0 and 160.0 kg.ha-1 of P2O5 and 60.0 kg.ha-1 of nitrogen combined to each other showed the best results for forage yield.

A study was carried out to determine the response of open pollinated sunflower (Helianthus annuusL. cv. Shumos) to boron fertilizer. Spring and autumn grown plots were sprayed with boron (0, 50, 100, 150, 200, and 250 mg L−1) in a randomized complete block design. The results showed that boron and green Leaf area/LAI measured at the end of seed filling were linearly related in the spring crop. In the autumn crop, the relationship between boron and dry matter yield was linear, and applications above 100 mg L−1significantly increased dry matter compared to the control. For the autumn crop, 100, 200, and 250 mg L−1significantly increased seed number compared to the control, but only the 150 mg L−1treatment increased seed weight significantly. Boron tended to decrease the empty seed percentage, and for the spring crop, this was incremental and linear with applications above 150 mg L−1leading to significant reductions in empty seed percentage. Seed yield increased linearly in the autumn crop in response to boron, and 200 and 250 mg L−1applications gave significant increases in yield compared to the control.

This study was conducted to evaluate effect of intercropping dates of lablab (Lablab purpureus L.) with maize (Zea mays L.) on forage and maize grain yields. It was carried out at Gereb Giba in Tanqua Abergelle district, Tigray, Ethiopia. Randomized Complete Block Design (RCBD) with four treatments and four replications were used. The treatments were sole maize sown (T1) and lablab sown at 10, 20 and 30 days after emergence of maize for T2, T3 and T4 respectively. Intercropping did not affect height and days for 50% flowering of lablab. Similarly, it was not affected height and days for physiological maturity of maize. Lablab forage yield was significantly greater (p<0.01) in T2 and T3 than T4. Maize Stover dry matter (DM) yield was similar among treatments while total forage DM yield was significantly higher (p<0.0001) in T2, T3 and T4 than T1. Moreover, among the intercrops, total forage yield was significantly highest (p<0.0001) for T2 compared to T4 but similar in T2 and T3. Maize grain yield was significantly superior (P<0.0001) in T2 and T3 compared to T1 and T4. Though, T2 and T3 had similarity in all parameters measured, T2 provided higher forage and maize grain yields than T1 and T4. Therefore, lablab intercropping at 10 days after emergence of maize is appropriate in Tanqua Abergelle district and other areas with similar agro ecologies.

American skullcap (Scutellaria lateriflora L.), a medicinal plant species valued for its sedative properties associated with flavonoids, is generally harvested from the wild. Scientific information on how field cultivation practices affect dry matter yield is lacking in this species. A 2 × 2 × 3 split plot factorial experiment within a randomized complete block design was conducted on a Marvyn loamy sand (fine-loamy, kaolinitic, Thermic Typic Kanhapludults) in Central Alabama to explore effects of light, irrigation, and nutrient application on dry matter yield of American skullcap. Treatment factors were shade (40% shade vs. no shade), irrigation (applied at 30 kPa vs. no irrigation), and nutrients [no added nutrients vs. nutrients added as chemical fertilizer (100 kg nitrogen, 68 kg phosphorus, 42 kg potassium/ha) or chicken litter (100 kg nitrogen, 50 kg phosphorus, and 123 kg potassium/ha)]. Shade formed the main plot units, whereas irrigation × nutrient factorial combinations were subplots. Skullcap shoots in experimental plots were harvested four times during the course of the two-year experiment (2007, 2008). All growth variables measured, except percent dry matter, performed better under shade than in full sun. Dry matter yield was increased 45% by shade, 61% by irrigation, and 22% by addition of nutrients. A significant irrigation × nutrients interaction was observed at the first and second harvests. Highest yields were obtained with the irrigation + manure and irrigation + fertilizer treatments under shade and the lowest with fertilizer and the control treatments in full sun.
