Background: Avena sativa L. (common oat) is the most important among the cultivated oat belongs to the Poaceae family and is known as Jai or Javi in Indian subcontinent. It is important winter forage in many parts of the world and is grown as multipurpose crop for grain, pasture, forage or as a rotation crop. Methods: A field experiment was conducted to study the effect of Zinc Sulphate and Borax on growth, yield components, yield and economics of oats seed production in red and lateritic soil of West Bengal during rabi seasons of 2015-16 and 2016-17 at agricultural farm, Institute of Agriculture, Visva-Bharati, Sriniketan, West Bengal. The experiment was laid out in Factorial Randomized Block Design having two factors each with four levels (Zinc Sulphate with 0, 15, 20 and 25 kg/ha as well as Borax with 0, 5, 10 and 15 kg/ha). Result: Pooled data over two years of experiments showed that soil application with Zinc Sulphate and Borax at various levels significantly influenced growth attributes (dry matter accumulation, leaf area index and crop growth rate), yield components (no. of panicles/m2, no. of filled grains/panicle and test weight), yield (seed yield, straw yield and biological yield) and economics of oats seed production. With increasing levels of ZnSO4 application, highest number of panicles/m2 (196.27), seed yield (3.00 t/ha), straw yield (6.94 t/ha) and biological yield (9.85 t/ha) were obtained at 25 kg/ha though these were at par with 20 kg ZnSO4 /ha. Higher number of filled grains/panicle (76.47), test weight (29.93 g), seed yield (2.95 t/ha), straw yield (6.70 t/ha) and biological yield (9.63 t/ha) were found with application of borax @ 10 kg/ha. The highest gross return, net return and return per rupee investment was achieved with application of ZnSO4 @ 20 kg/ha (₹ 1,17,257/ha, ₹ 68,997/ha and 2.65, respectively) which was significantly higher than both of 25 kg ZnSO4/ha (₹ 1,15,051/ha, ₹ 64,489/ha, and 2.52, respectively) and 15 kg ZnSO4/ha (₹ 1,05,198/ha, ₹ 59,240/ha and 2.44, respectively). Similarly, highest gross return, net return and return per rupee investment was obtained with application of borax @ 10 kg/ha (₹ 1,15,537/ha, ₹ 69,070/ha and 2.67, respectively). A significant interaction between Zinc Sulphate and borax was found towards seed yield, biological yield, gross return, net return and return per rupee investment in oats seed production. Use of ZnSO4 at 20 kg/ha and borax at 10 kg/ha conjunctively achieved highest seed yield (3.28 t/ha), biological yield (10.81 t/ha), gross return (₹ 1, 27, 530/ha), net return (₹78,760/ha) and return per rupee investment (₹3.78) in oats seed production.

“…This was significantly higher than the application of N80 P40 K40 (25.93 t ha -1). These results were in conformity with the findings of Singh et al (1990), Pradhan and Mahapatra (1995) and Joshi et al (1996). At first cutting, the highest dry fodder yield was obtained with the application of N120 P60 K60 (3.37 t ha -1 ).…”

A field experiment was conducted during rabi season of 2006-2007 and 2007-2008 at Agriculture Research Farm of Palli Siksha Bhavana, Visva-Bharati to study the “Influence of cutting and fertilizer management on growth and yield of fodder oats (Avena sativa L.)”. Various growth attributes (viz. dry matter accumulation and leaf area index) of fodder oats were influenced significantly with different levels of fertilizer management. An increasing trend was found in dry matter accumulation and leaf area index of oats with the advancement of growth of the crop up to 60 days when 1 st cutting was taken. A significant response from cutting and fertilizer management was found on total green and dry fodder yields of oats. The highest green and dry fodder yields were achieved from fertilizer schedule of N 120 P60 K 60 kg ha -1 both at single cutting and two cuttings management. Significantly higher total green and dry fodder yields were obtained from two cut management (29.74 and 7.92 t ha -1 , green and dry fodder respectively) when compared with single cut management (14.68 and 3.37 t ha -1 , respectively), indicating the scope of getting two cuttings from fodder oats in red and lateritic belt of West Bengal.

“…Both fertilisers were also equally effective in increasing foliar N concentration of ryegrass. This agrees with results on Italian ryegrass in South Africa (Eckard 1990b), oats (Joshi and Prasad 1977) and pangola grass in Australia (Lowe and Cudmore 1978). Neither could we show any evidence to suggest that their effects on soil N (i.e.…”

Dairy farms in subtropical Australia use irrigated, annually sown short-term ryegrass (Lolium multiflorum) or mixtures of short-term ryegrass and white (Trifolium repens) and Persian (shaftal) (T. resupinatum) clover during the winter–spring period in all-year-round milk production systems. A series of small plot cutting experiments was conducted in 3 dairying regions (tropical upland, north Queensland, and subtropical southeast Queensland and northern New South Wales) to determine the most effective rate and frequency of application of nitrogen (N) fertiliser. The experiments were not grazed, nor was harvested material returned to the plots, after sampling. Rates up to 100 kg N/ha.month (as urea or calcium ammonium nitrate) and up to 200 kg N/ha every 2 months (as urea) were applied to pure stands of ryegrass in 1991. In 1993 and 1994, urea, at rates up to 150 kg N/ha.month and to 200 kg N/ha every 2 months, was applied to pure stands of ryegrass; urea, at rates up to 50 kg N/ha.month, was also applied to ryegrass–clover mixtures. The results indicate that applications of 50–85 kg N/ha.month can be recommended for short-term ryegrass pastures throughout the subtropics and tropical uplands of eastern Australia, irrespective of soil type. At this rate, dry matter yields will reach about 90% of their potential, forage nitrogen concentration will be increased, there is minimal risk to stock from nitrate poisoning and there will be no substantial increase in soil N. The rate of N for ryegrass–clover pastures is slightly higher than for pure ryegrass but, at these rates, the clover component will be suppressed. However, increased ryegrass yields and higher forage nitrogen concentrations will compensate for the reduced clover component. At application rates up to 100 kg N/ha.month, build-up of NO3–-N and NH4+-N in soil was generally restricted to the surface layers (0–20 cm) of the soil, but there was a substantial increase throughout the soil profile at 150 kg N/ha.month. The build-up of NO3–-N and NH4+-N was greater and was found at lower rates on the lighter soil compared with heavy clays. Generally, most of the soil N was in the NO3–-N form and most was in the top 20 cm.
