Fodder Yield

The scope of increasing the cultivated area under forages is rather limited, because of mounting pressure on need for food and commercial crops, but there is a large demand for green and dry fodder from livestock industry. Hence, fodder production has to be increased per unit area per unit time. By practicing the de-topping in commercial grain maize we can increase the fodder production, quality and it also reduces the deficit of fodder to some extent. Reviews indicated that by de-topping of maize, there may be slight reduction in grain yield of maize but by doing it at right stage/time and at right plant height it gives highest net returns than no de-topped treatments. De-topping at 30 days after silking; removing the top 6 leaves or after physiological maturity; removing all the leaves above the cob or de-topping above 10th internode gives highest fodder yield and net returns with slight or no reduction in grain yield.

Cowpea Variety

A field experiment was conducted to examine the effect of plant spacing on grain and fodder yield of four cowpeas varieties. Four cowpea varieties i.e. Asetenapa, Asomdwe, Hewale and Videza were sown with three plant spacing i.e. 30 x 15 cm, 45 x 15 cm and 60 x 15 cm at Samboligo in the Bongo District of the Upper East of Ghana.  The experiment was laid in randomized complete block with four replicates in factorial fashion. Cowpea variety and plant spacing significantly influenced grain yield, 1000 seed weight, nodules per plant and plant height. Plant spacing had no significant effect on stem girth, pods per plant, pod length and seed per pods. Variety ‘Hewale’ produced the highest grain yield of 991.3 kg ha-1 while Asetenapa produced the highest fodder yield of 1025.5 kg ha-1. Interactive effect between Asomdwe and 45 x 15 cm had the highest 1000 seed weight (170.6 g) while Asetenapa and 30 x 15 cm produced the highest grain yield (1072.9 kg ha-1). Variety ‘Hewale’ is recommended for commercial grain production while Asetenapa for fodder production. Asetenapa and 30 x 15 cm combination is recommended for commercial grain production.

Forty five hybrids derived from a diallel mating design of ten parents and one standard check PUSA CHARI-121 were evaluated for general and specific combining ability effects and standard heterosis for grain yield/plant, dry fodder yield/plant, days to 50 per cent flowering, plant height, number of leaves/plant, leaf length, leaf breadth and 100- seed weight of Sorghum bicolor. The mean square due to general and specific combining ability was significan for Days to 50% flowering, Days to maturity, Plant height (cm),No of Leaves/plant, Leaf length (cm), Leaf width (cm), seed yield/plant (g), Fodder yield/plant (q/ha) and 100-seed weight (g) for all the characters. Both additive and non additive genetic effects were present in the material under study. However the ratio of σ2gca/ σ2sca suggested that the preponderance of non additive gene action in expression of all the characters under study. Out of the nine parents PUSA CHARI-121, PANT CHARI-4, MP CHARI, PANT CHARI-6 and PANT CHARI-5 identified as good general combiner for grain yield/plant, dry fodder yield/plant and other agronomical traits. The hybrid HC-136 x PANT CHARI-4 and PANT CHARI-4 x PUSA CHARI-121 for grain yield/plant and hybrid MP CHARI x PANT CHARI-6, PANT CHARI-5 x SPV 1616 and HC-136 x PANT CHARI-4 for dry fodder yield/plant exhibited higher magnitude of positive significant specific combining ability effect with highest standard heterosis and per se performance. These hybrids were also found suitable for two or three yield contributing traits. In general, close association between specific combining ability effects and standard heterosis was observed among the best hybrids identified on the basis of specific combining ability effects for grain and dry fodder yield.

Height Data

The effect of CCC on the grain yield of two Australian and two Mexican semi-dwarf cultivars, with two seeding rates, and two levels of N fertilizer, was studied in the held. Grain yield increases, particularly in CV. Timgalen, were produced by CCC through the control of lodging, an increase in the number of grains per ear and an increase in the number of ears per unit area. Even where only a small effect on height was produced in CV. Pitic 62, the grain yield was increased as a result of more ear-bearing tillers. No significant grain yield increases were found in R.K.F. The delay in ear emergence in some cultivars as a result of CCC did not change the number of florets formed but it may have improved floral fertility as indicated by the higher number of grains per ear at harvest. The differential response of the cultivars to CCC is demonstrated by the plant height data. In decreasing order of height reduction they were Robin, Timgalen, Pitic 62 and R.K.F.

The application of N at the appropriate time and dose can increase oat crop efficiency by increasing grain yield through changes in production components. High doses of N, depending on the genotype and the environment, can result in plant lodging, which can be addressed with the use of growth retardants. The aim of this study was to evaluate the yield components, lodging, and productivity of white oat cultivars cultivated at two planting locations under different N levels with trinexapac-ethyl growth retardant. Two assays (with and without the application of the growth retardant agent) were used in the experiments, which were set up in the region of Londrina and Mauá da Serra, Parana State, Brazil, in a randomized block design with split plots and four replications. The plots consisted of four white oat cultivars (IPR Afrodite, IPR Artemis, URS Corona, and URS Guria) and the subplots of four doses of N (0, 30, 60, and 90 kg ha-1). Plant height, number of panicles per unit area, number of grains per panicle, thousand grain weight, lodging of plants, and grain yield were evaluated. For the conditions under which the experiments were conducted, the growth regulator decreased plant height and lodging. Furthermore, the growth regulator in combination with N topdressing increased the number of panicles per unit area. Thus, the increase in grain yield with the application of a growth retardant was dependent on the characteristics of the plant growth environment. The response of genotypes to N fertilization was also dependent on the soil and climatic characteristics of the environment.

A field experiment on the standardization of organic module for production of fenugreek (Trigonella foenum graecum L.) was conducted during rabi season of 2009-10 to 2012-13 (four years). The experiment was laid out in Factorial Randomized Block Design (RBD) consisting of three organic modules (M1, M2 and M3) and two fenugreek varieties (AFg-1 and RMt-305) with four replications. Findings of present study showed significant differences among the performance of different organic modules tested for two fenugreek varieties. Organic module-1 (M1)comprising of soil application of vermi-compost @5 t/ha+ foliar spray of 5% garlic extract @ 2.0 kg/ha + 2% neem oil @ 5 litre/ha+ soil application of neem cake @150 kg/ha and Trichoderma @ 2.5 kg/ha, seed treatment with Rhizobium @100 ml/kg seed, PSB @ 100 ml/kg seed and Trichoderma @10 g/kg seed exhibited earliest seed germination and maximum plant height (5.78, 19.69, 43.39 and 50.97 cm) at 30, 60, 90 DAS and at harvest, respectively with maximum number of branches (6.76/ plant), number of pods (42/ plant), number of seeds (16.01/ pod), highest grain yield (1515.21 kg/ha), gross return (100004) and net returns (66741) in fenugreek crop. Similarly significant differences were recorded in the performance of fenugreek varieties under different organic modules and the highest plant height, maximum number of branches and pods per plant, highest number of seeds per pod with maximum grain yield (1568.36 kg/ha), gross returns (103512), net returns (71399) with higher B:C ratio (2.22) were recorded in fenugreek variety AFg-1 than variety RMt-305. Cultivation of fenugreek variety AFg-1 with the application of Module-1 exhibited maximum values for all the growth parameters, yield attributing characters, maximum grain yield, net returns with improvement in soil organic carbon % (OC) and soil fertility (available N, P and K) after 4 crop cycles. Hence, variety AFg-1 is recommended to grow organically with the application of Module-1 (M1) under semi-arid environmental conditions

One of the basic agronomic practices to improve the yield of chickpea are ideal sowing date and high yielding varieties. Thus, a field experiment was conducted to assess the effect of different sowing dates on yield and yield components of chickpea varieties in the main cropping season of 2019 at Toke Kutaye District. Four sowing dates (September 4th, September 14th, September 24th, and October 5th) and four kabuli varieties. Four Kabuli types of chickpea varieties were Dalota, Ejere, Teji and Dube (local check). Experiment was laid out in split plot design using factorial arrangement with three replications and sowing date treatments were assigned to the main plots and varieties to sub plots. The main effect of sowing date showed highly significant effect on days to emergence, days to 50% flowering and physiological maturity. Highest days to emergence                (12.4 days) were recorded from a plot sown on October 5th, while longest days to 50% flowering (54.92 days) and physiological maturity (122.5 days) were recorded from a plot sown on September 14th. Moreover, varieties had significant effect on days to physiological maturity of chickpea. Longest days to physiological maturity (133 days) were recorded from local variety and early days to physiological maturity (113.3 days) was recorded from Dalota variety. The main effects of sowing date and variety were significant on plant height, as the tallest plant height (42.75 cm) was recorded from September 24th sown plants. Similarly, the tallest (41.42 cm) plant was recorded from Dalota variety. In addition, the highest number of primary branches (6.83) and secondary branches (16.42) per plant were recorded from Dalota variety, while the lowest number of primary branch (5.5) and secondary branches (8) were scored from Ejere and Teji varieties, respectively. Highest grain yield (2415.4 kg ha-1) was obtained from plots sown on September 14th whereas Dalota variety produced highest grain yield (2051.25 kg ha-1). Hence, Dalota variety and September 14th sowing date emerged as best among all tested treatments and can be recommended for chickpea production in the study area and similar agro-ecologies. Conclusive recommendation could be obtained if the study is repeated at more locations and seasons in the future.

The herbicide saflufenacil is a Protox inhibitor, with differential translocation mode in comparison to other herbicides with the same mechanism of action. Selectivity, efficacy and safety to the environment are important characteristics for practical application of a herbicide in agriculture. The aim of this study was to determine the tolerance of ten dry bean cultivars to saflufenacil, applied on preemergence. The experiment was conducted in split plot randomized blocks design with ten dry bean cultivars (IAPAR 81; IPR Tiziu, IPR Corujinha; BRS Estilo; BRS Talismã; BRS Esplendor; BRS Campeiro; BRS Radiante, BRS Vereda and Jalo Precoce) allocated in plots and saflufenacil concentrations (0, 14.7 and 29.4 g ha- 1) in subplots. Evaluations were performed at 21 and 28 days after application (DAA) and plant height at 28 and 35 DAA. At physiological maturity were evaluated plant height, first pod height , number of pods per plant, 400 grains weight and dry beans grain yield. The cultivar Talismã showed low sensitivity to the herbicide and the cultivar Jalo Precoce high sensitivity to the herbicide, considering all variables analyzed.

The influence on grain yields and agronomic characteristics of spring wheat was determined when P and K fertilizers were applied singly up to 448 kg/ha and to 996 kg/ha when combined.The combined PK fertilizers resulted in a highly positive interaction and increased grain yields from 2,461 to 4,036 kg/ha when applied at rates up to 224 kg/ha of each nutrient. A slight reduction in yield occurred at the highest combined levels of both elements. Small significant increases in grain yield were obtained from the single applications of K, but P alone did not alter yield.Increased plant height, straw, grain and kernel weights were obtained. Days to mature were reduced from 95 to 91 or 92, and a slight reduction in strength of straw occurred. Plant height and yield were correlated because height and straw weight were strongly associated. Kernel weight was highly correlated with grain weight, which in turn had a marked positive effect on yield.
