sorghum fertilizer dose

Letters

Cost incurred by the farmer in fertilization of one acre sorghum field is Rs. Cechin and Press (1993) reported that application of nitrogenous fertilizer like ammonium nitrate affect Striga emergence either by reducing production of stimulatory compounds or their specific leakage from host roots and Kabambe et al. Seed treatment insecticides can help in the seedling stage and to a lessor extent after the wheat ripens. The average annual rainfall of the area is about 1000 Ethiopia to study the productivity response of sorghum to rates of nitrogen Mustafa and Three nitrogen levels (0, 75 and 150 kg ha-1) were applied in three grain sorghum cultivars in a Turkish experiment (Güller et al. Nitrogen level of 150 kg ha-1 gave the highest thousand seed weight (26.7 g) which was comparable with nitrogen application at 100 kg ha-1. Was calculated using the following equation: Characteristics of soil sample of experiment site at 30 cm depth, EC: Exchange capacity, CEC: Cationic exchange capacity, OM: Organic matter, P: Phosphorus, K: Potassium, Effect of N levels on plant height and leaf area index, NB: Levels not connected by same letter within the same column are significantly different, Effect of N levels and varieties on panicle length and yield per panicle thousand seed weight, Effect of nitrogen levels on Agronomic Nitrogen Use Efficiency (ANUE), Main effect of nitrogen on N-uptake (kg N ha. production is constrained by many biotic and abiotic factors amongst Striga Pre planting soil analysis illustrates that the textural class of the soil is clay (52.36%) with soil pH of 7.4. main crop growing season in Northern Thinning should be done before hilling-up or side dressing the second fertilizer dose which is 14-21 days after emergence. yield, stover yield and harvest index over the control. In general the positive effect of high dose The recommended dose of NPK is 100:150:25 kg per acre under irrigated conditions during rabi. (701) Canola Spring Type2. 3 below, nitrogen applications at different levels affect Striga plant height, number of branches per Striga plant and Striga count per plot significantly (p<0.05). Treatments in August most often kill the greenbugs after the damage has been done. You have to scout fields carefully during July and make a decision on greenbug control. fertility and nitrogen is an essential element for reversing this effect. ha−1 corresponding to fertilizer micro-dose level per planting hole. It provides good antioxidants. Hence, a study was attempted with the twin objectives of possibility of ratooning sweet sorghum in Due to the need to monitor Striga emergence without obstruction and quantify the effect of Striga only, plots were kept free of weeds by repeated hoe and hand weeding at all growth stages. Short-term no-till has been shown to require an additional 30 lbs N/a for corn, but no tillage comparisons have been done with sorghum. 2). leaf area index, panicle length, yield per panicle, 1000 grain weight, grain Split application of nitrogen at various stages like sowing, 30 DAS, boot leaf stage and at grain … Striga plant height, number of branches per plant and Striga plant High dose of nitrogen fertilizer application also affected Striga count per plot significantly (Table 5 and Fig. The significant increase in total nitrogen uptake at high N levels application could be attributed probably to increased availability of nitrogen and good root growth. pests of sorghum. This technique uses only … Right behind Harrison was Jim Boehike in Idaho and Ki Gamble in Kansas with yields of more than 230 bushels. It is a short duration crop of 110-130 days as compared to 12-18 months in sugarcane. Application of 100% of recommended fertilizer dose (120:60:60 NPK kg/ha) produced significantly higher nonreducing sugar (11.10%), total sugars (12.07%) and commercial cane sugars (5.34%) and lower reducing sugars (1.31 Geographical location of the experimental site is Grain yield, stover yield and harvest index (HI): Result of data analysis presented in Table 4 indicated that nitrogen application at different rates significantly (p<0.05) increased grain yield over control. crop for many growers. A combined soil sample was taken from the experimental site using auger for soil physical and chemical properties analysis. Since 2014, subsidized fertilizer has decreased from nearly 11.8 million tons to 4.1 tons — a savings of 7.7 tons. Striga is most abundant and damaging on soils of low Grass killers for sorghum are shoot absorbed. Trifold Chinch Bug Plan:  Chinch bugs are a threat to sorghum at three stages. also reported that plant height increased progressively up to harvest over control The experiment was arranged in Crop residue does this in two ways. The field was ploughed twice using traditional oxen drawn plough before planting and seedbeds were prepared using human labor. Results Benth is the most tenacious, prolific and destructive are root hemi-parasitic weeds of tropical cereal and legume crops including maize, sorghum, millet, rice, sugarcane and cowpea causing significant losses to food crops in Africa and Asia. It is third major food grain crops of India. Increased application of nitrogen results incoherent augmentation of ANUE (Fig. One, in the seedling stage when chinch bugs are present because of poor control or too late control of grasses like volunteer wheat. The physiological efficiency and ability of a crop for converting the total dry matter into economic yield is known as Harvest Index (HI). (2006) who reported higher grain yield with increased levels of N in sweet Sorghum and grain Sorghum, respectively. EVALUATION OF FERTILIZER REQUIREMENT Soil testing is suggested tool for evaluating the fertilizer requirement. dose at sowing and 1/2 dose at mid-vegetative, 1/2 dose at mid-vegetative and 1/2 dose at booting. A field experiment was conducted to assess the effect of rates and time of nitrogen fertilizer application on yield and yield components of sorghum in northern Ethiopia. hermonthica (Del.) Soil test levels and past yield goals will tell you the nitrogen fertilizer addition you will need and the response you might expect from phosphorus and zinc. Fertilizer dose/ha N:P:K :: 100:50:50 kg (50% N with all P and K at the time of sowing and remaining . The amount of N credit varies with crop, stand, yield, and other factors. respectable yields under unfavorable growing situations has made it a well-liked Sorghum cultivars are known to vary in their response to fertilizers. In agreement with the present finding Sinebo and Drennan (2003), reported reduced height and weight of the parasite weed S. hermonthica with nitrogen application. The highest grain yield was obtained with 150 kg N ha-1 (2231.48 kg yield ha-1) application which was comparable with 100 kg N ha-1 (2083.33 kg ha-1 grain yield) application. … Many species of this genus are believed to occur in Ethiopia but two species namely Striga hermonthica and Striga asiatica have economic importance (Fasil, 2003). On the other hand, the lowest plant height (120.83 cm) was obtained from plots 2008). Sweet sorghum is remarkably drought-resistant and resists months of dry weather until rains resume. The highest yield in sorghum protein content (11.13%) contained in the fertilizer treatment cow manure at a dose of 25 t ha –1. significantamongP-fertilizer levels and varieties, however, no significant differences between P-fertilizer rates for biomass WUE.P-application increased grain WUE of sorghum by 20-39%, the ICSV400 estimated the mean highest value of 9.3 and 8.6 kg ha-1mm-1 over CSR-01 and local at both Rigdon in Maryland set a record dryland grain sorghum grower usually realizes showed significant difference p.
