    (CCSHAU Hisar, 2022-09) Baljeet Singh; Mukesh Kumar
    An experiment was conducted at research field of Deendayal Upadhyay Centre of Excellence for Organic Farming, CCS HAU, Hisar during the year 2021-22 to study the effect of different irrigation levels and mulching methods on performance of organically cultivated papaya. The experiment comprised of twenty one treatments under the drip irrigation method with combination of three different irrigation levels viz. 50%, 75% and 100% of crop water requirement and seven mulching methods. The results showed that the plant height (240.73 cm), stem girth (46.03 cm), crown diameter (245.40 cm), number of flowers (65.67), number of fruits (42.67), yield per plant (54.30 kg) and total yield (135.75 t ha-1) were observed maximum for meeting 100% of crop water requirement with the application of 10 cm thick straw mulch in two-meter diameter around the plant and minimum for meeting 50% of crop water requirement without mulch condition. The soil moisture (20.18%) was found maximum for meeting 100% of crop water requirement with the application of plastic mulch in twometer diameter around the plant and minimum for meeting 50 % of crop water requirement without mulch condition. From the results, it is also observed that the irrigation water use efficiency (59.53 kg m-3) was found maximum for meeting 50 % of crop water requirement with 10 cm thick straw mulch in two-meter diameter around the plant and minimum (42.64 kg m-3) for meeting (42.64 kg m-3) 100% of crop water requirement without mulch under drip irrigation system.

    Development and Performance Evaluation of Machine for Dehulling of Hempseed (Cannabis sativa L.)
    (hisar, 2022) Mittal, Vipul; Gupta, Ravi
    The study was conducted to develop a hempseed dehuller machine for dehulling of hempseed (Cannabis sativa L.). The development of the machine was based on a 2D design made from AUTOCAD software. The raw hempseeds were cleaned and graded for observation of their engineering properties. To study the effects of dehulling process variables on the dehulling efficiency of hempseeds, two seed grades: Medium (3 – 3.5 mm), Large( ≥ 3.5 mm), four levels of valve opening (100, 75, 50 and 25 % ) and five levels of initial seed moisture content (2-4, 4-6, 6-8, 8-10, 10-12 %) (wb) were selected by conducting preliminary trials. Statistical analyses viz., correlation and regression analysis of the responses was performed to estimate the coefficients of the fitted equation of the responses and to check the significance of the regression coefficients of independent and interaction variables, respectively. A three-phase (0.75 kW) electric motor was used for the power supply of the machine. The performance of the dehuller was found optimum at 2100 rpm, feed valve opening of 50% and fed with raw hempseeds of medium grade at 6-8 % MC range. At these levels of independent variables the throughput capacity, dehulling efficiency, output capacity and broken were found to be 67.4 kg/h, 38.7%, 26.25 kg/h and 8.84%. The break-even point, benefit-cost ratio and payback period for the machine were found to be 4223 units of hemp kernel, 1.029 and 0.237 years respectively. The developed machine for dehulling of hempseed was found energy-efficient, economically usable, and capable of maintaining the good quality of hempseed kernels.

    Response of onion with different irrigation frequency and lateral spacing under subsurface drip system
    (CCSHAU, Hisar, 2021-08) Deokar Gopal Kathalu; Sanjay Kumar
    An experiment was conducted to study soil water dynamics and yield response of onion crop with irrigation frequencies (one, two, three and four days) and lateral spacing (45cm and 60cm) under subsurface drip irrigation during the spring summer season 2020 and 2021 in 2m x 2m micro plots, built in the field area of Department of Soil and Water Engineering, CCSHAU, Hisar, Haryana, India. At the middle of 45cm and 60cm lateral spacing with daily irrigation, available moisture in the root zone (0-60cm) was 12.73cm and 12.33cm respectively, which was higher by 3.14% in 45cm lateral spacing than 60cm. Average highest (102.28 g) fresh weight of onion bulb and number of bulbs per m2 for grade A, B and C of onion of two seasons was recorded in I2L45 treatment. Highest bulb yield of onion under grade A (>5.0cm), B (4.0-5.0cm) and C (4.0-5.0cm) was recorded in I2L45 treatment, whereas its lowest value under the respective grades was obtained in I4L60 treatment. Under two days irrigation interval with 45cm lateral spacing (I2L45), the total bulb yield was obtained 9.98% higher than 60cm lateral spacing (I2L60) treatment during year 2020, whereas, it was 9.22% higher in year 2021. The highest (11.55 kg m-3 in 2020 and 10.09 kg m-3 in 2021) and lowest (9.99 kg m-3 in 2020 and 9 kg m-3 in 2021) irrigation water use efficiency was observed in I2L45 and I4L60 treatments, respectively. On the basis of soil water dynamics, superior quality and highest yield of onion in sandy loam soil, it is concluded that subsurface drip irrigation with two days irrigation interval with 45cm lateral spacing gives better performance as compared to one, three and four days irrigation in 45 as well as 60cm lateral spacing.

    Effect of wind speed and spacing on distribution uniformity of sprinkler irrigation system
    (CCSHAU, Hisar, 2020-12) Raj Kumar; Ram Naresh
    An experiment was conducted to study the effect of wind speed (0-4 km/h, 4-8 km/h and 8-12 km/h), direction (North-West and North-East) and spacing (6 m × 6 m, 6 m × 9 m and 9 m × 12 m) on uniformity distribution of sprinkler irrigation system at the field of the village Luhana located in Western Haryana., India. For spacing 6 m × 6 m and wind speed range 0-4 km/h, the maximum distribution uniformity was 86.33%. Similarly at ranges of wind speed 4-8 km/h and 9-12 km/h, the average distribution uniformity was 82.88% and 81.42% respectively. For spacing 6 m × 9 m was used, the average distribution uniformity was 75.42% at a range of wind speed 0-4 km/h. Similarly at ranges of wind speed 4- 8 km/h and 8-12 km/h, the average distribution uniformity was 75% and 74.16% respectively. For spacing 9 m × 12 m was used, the average distribution uniformity was 68.20% at a range of wind speed 0-4 km/h. Similarly at ranges of wind speed 4-8 km/h and 8-12 km/h, the average distribution uniformity were 66.17% and 66.60% respectively. It shows that the combination of spacing 6 m × 6 m and wind speed 0-4 km/h gives a higher distribution uniformity. From this it is evident that for maintaining distribution uniformity more than 75%, for wind speed 0-4 km/h sprinkler spacing should not be more than 6 m x 9 m and for wind speed 4-8 km/h sprinkler spacing should not be more than 6 m x 6 m while for wind speed range 8-12 km/h should be less than 6 m x 6 m.

    Effect of cryogenic treatment on the performance of straw combine blade.
    (CCSHAU, Hisar, 2021-07) Jakhar, Chander; Kumar, Anil
    The harvesting machines (combine, reaper and straw combine) are developed to overcome the shortage of labor and timely operations and also to facilitate the multi cropping sequence in India. The cutting blades are made up of high carbon steel having carbon content ranging from 0.60 to 1.00 percent. The carbon is the main element for higher strength and hardness of cutting steel blades. However, during cutting at high temperature and in abrasive environment, these cutting materials faces excessive surface degradation which ultimately reduces the life of the blade and increased cutting cost of the machine. In recent times the cryogenic treatments have positive effect to improve the wear resistance, hardness and life of the cutting tools. The present study was undertaken to improve the mechanical properties of cutter bar blade (A type) and chopping cylinder blade (M type) of straw combine with cryogenic treatment. For this, the laboratory testing was done in Tribology laboratory of NIT, KUK, Kurukshetra, whereas, field testing was done at farmers field in Ludas and Sahpur village of Hisar district. In laboratory experiment three replication of load (15, 20 and 25 N), time (150, 300 and 450 s) and sliding velocity (1.31, 2.61and 3.92 m s-1) were used for wear analysis. The wear analysis was done by using Pin on disc wear testing machine. The diameter and the length of the coated and uncoated high carbon steels specimens for testing were 10 and 35mm, respectively. In uncoated specimens, the wear was significantly affected by load followed by sliding velocity and time, whereas in coated specimen, the load was the only significant parameter to affect the wear properties of the specimens. The time and sliding velocity had negligible effect on the coated specimens. During field testing, the coated and uncoated blades were installed on the straw combine and operated for 38.33 hours. The wear of the blades was analyzed with respect to the weight and dimensions of the blades before and after work. The wear (%) in cutter bar and chopping cylinder blades for uncoated and coated were found as 2.82, 0.69 and 1.48, 0.41%, respectively. The cryogenic treatment resulted in increase of 9.38 and 13.61% cost of the cutter bar and chopping cylinder blades, respectively. This increased cost was fully justified by the increased cutter bar and chopping cylinder blade life by 75 and 72 %, respectively.
