    Performance of barley varieties under Populus deltoides based agroforestry system
    (CCSHAU, Hisar, 2021-08) Ashish Kumar; Ahlawat, K.S.
    The present investigation entitled “Performance of different barley varieties under Populus deltoides based agroforestry system” was carried out at the research area of Department of Forestry, CCS Haryana Agricultural University, Hisar during 2019-20. The performance of five barley varieties (BH 946, BH 959, BH 393, BH 885 and BH 902) grown under poplar plantation and as sole crop were examined to ascertain the effect of environment on growth, physiology, yield attributes and yield. The various growth, physiological and yield attributing parameters of different barley varieties were observed significantly higher in sole barely crop (devoid of trees) than under poplar plantation except chlorophyll content, relative water content, relative stress injury, canopy temperature depression. The plant population/m2 , number of effective tillers/m2 and test weight of variety BH 885 was maximum, however yield of BH 885 was lesser than other barley varieties (BH 946, BH 393 and BH 902). A significant reduction was observed in yield of different barley varieties under poplar plantation. The maximum reduction of 23.39 % was observed in variety BH 959 followed by BH 885 (21.34 %), BH 902 (18.26 %), BH 393 (16.33 %), and it was minimum in variety BH 946 (15.19 %). The B:C ratio was maximum in BH 946 (1.22) followed by BH 393 (1.12), BH 902 (1.11), BH 885 (0.96) and minimum in BH 959 (0.89) under poplar plantation. Soil pH and EC were decreased more significantly under poplar plantation than sole barley crop. A significant increase in soil organic carbon, available N, P, K and DTPA extractable micronutrients (Zn, Cu, Mn and Fe) was observed at all depths (0-15, 15- 30 and 30-45 cm) under poplar plantation than sole crop. The total N, P K and micronutrients uptake was observed maximum in variety BH 946 and minimum in BH 959. The moisture content was observed higher under poplar plantation than sole crop at all the soil depths. Furthermore, the soil moisture content increased along with an increase in distance from the tree line. The average per cent reduction in light available to understory crops was maximum in November (60.22%) and minimum in February (35.62%). The temperature was observed slightly lesser under poplar plantation than open environment (devoid of trees), however a reverse pattern was observed in case of relative humidity.

    Optimization of irrigation frequency for onion crop under subsurface drip system
    (CCSHAU, 2019) Ashish Kumar; Sanjay Kumar
    An experiment was conducted to study the effect of lateral spacing (45 cm and 60 cm) and drip irrigation frequencies (one, two, three and four days) on onion crop (Agrifound dark red variety) during kharif season 2018 in micro plots (2 m x 2 m) constructed in lab area of Department of Soil and Water Engineering, COEA&T, CCSHAU, Hisar, Haryana, India. For 60 DAT, in daily irrigation at 45 cm lateral spacing, available moisture (9.78 cm) in the root zone (0-60 cm) at the middle of two laterals was observed higher (15.6%) than at 60 cm lateral spacing where available moisture was 8.46 cm. The highest yield in A (> 5.0 cm), B (4.0-5.0 cm) and C (3.0-4.0 cm) grade of onion was observed as 0.76, 0.54 and 0.31 kg m-2 in two days irrigation frequency with 45 cm lateral spacing. The highest marketable yield of onion (155.23 q ha-1) was observed in two days irrigation frequency with lateral spacing of 45 cm. Among the different treatments, lowest unmarketable yield was observed in two days irrigation frequency with lateral spacing of 45 cm. These parameters show that better quality of onion was obtained in this treatment. The highest yield of onion (175.67 q ha-1) was obtained in two days irrigation frequency with lateral spacing of 45 cm which was 16.8% higher than two days irrigation frequency with lateral spacing of 60 cm. Irrigation water use efficiency was found to be highest (10.23 kg m-3) in two days irrigation frequency with lateral spacing of 45 cm. On the basis of moisture distribution pattern, better quality and highest yield of onion, two days irrigation frequency with 45 cm lateral spacing is the most preferable treatment in sandy loam soils.

    Agrometeorological Analysis of Okra Cultivation in Spring-Summer Season
    (CCSHAU, 2019) Ashish Kumar; Surender Singh
    A field study was conducted in Chaudhary Charan Singh Haryana Agricultural University in the research farm of Department of Agricultural Meteorology entitled “Agrometeorological Analysis of Okra Cultivation in Spring-Summer Season” with the objectives to quantify various agrometeorological indices for different phenophases and to examine the relationship between weather variables and yield attributes of Okra. The experiment was conducted in split plot design with four dates sowing (2, 12 and 22 March and 2 April) and three varieties (Hisar Unnat, Hisar Naveen and Varsha Uphar) in 3.0 x 3.0 m plot with 30 cm x 10 cm spacing. The results showed that Hisar Naveen resulted into significantly higher growth parameters like plant height (122.20 cm at 90 DAS), LAI (2.22 at 90 DAS), leaf dry matter (25.97 g/plant at 90 DAS), number of branches per plant (2.1), yield attributes like fruit length (8.21 cm); fruit weight (7.30 g), fruit diameter (1.40 cm) and yield (120.3 q/ha) and 22 March of sowing of okra found to be the most suitable date. The different weather indices like GDD (301.040 C day at germination to 763.52 0C day at first picking), Heliothermal units (567.470 C day hours at germination to 55576.460 C day hours first picking), Photothermal units (927.110 C day hours at germination to 9593.170 C at first picking), Hydrothermal units (6094.200 C days hours at germination to 47685.460 C days hours) ; heat use efficiency (0.4140 C at first picking to 1.1520 C day hour at physiological maturity); heliothermal use efficiency (0.590 C day hour at first picking to 0.190 C day hour at physiological maturity); photo thermal use efficiency (0.320 C day hour at first picking to 0.780 C day hour at physiological maturity); hydrothermal use efficiency (0.199 kg/ha 0C day at first picking to 0.512 kg/ha 0C day at physiological maturity) and photothermal index (16.24 kg/ha 0C day at germination to 17.60 kg/ha 0C day at first picking) were found better in okra crop sown on 22 March while Hisar Naveen variety was superior in using the agrometeorological parameters like maximum and minimum temperature, actual vapour pressure during morning and evening; relative humidity during morning and evening; wind speed; sunshine hours; evaporation and rainfall. The regression equation (R2) ranged from 0.51; 0.56; 0.52; 0.71 for GDD; Heliothermal units; photothermal units; hydrothermal; units and hydrothermal use efficiency, respectively.

    (CCSHAU, 2018) Ashish Kumar; Dhillon, R.S.
    The present investigation entitled ―Performance of field crops and eucalyptus clones under agri-silvicultural system‖ was carried out at research area of Forestry Department, CCS Haryana Agricultural University, Hisar during kharif and rabi seasons of 2016-17. The experiment was carried out to study the effect of different eucalyptus clones (C-83, C-7, C-413 and C-288) on the performance of field crops (cowpea and barley) as well as changes in chemical properties of soil. The maximum plant height (9.69 m), basal diameter (12.37 cm) and diameter at breast height (9.52 cm) was recorded in eucalyptus clone C-413. However, the maximum (2.36 m) crown width was attained by C-288 clone. Plant population, plant height, fresh leaves and stem weight, green fodder and dry matter yield of cowpea were found significantly higher under C-83 as compared to other clones under study. The crude protein yield of cowpea was also recorded higher under C-83 (1.02 t/ha) clone while percent crude protein of cowpea was recorded maximum (12.20 %) under C-413 clone. Different growth parameters viz. plant population, number of tillers, number of spikes, number of grains per spike, test weight of barley was of barley also found higher under C-83 clone as compared to other clones. Plant height of barley at different stages of growth was observed significantly higher under the plantation of C-83 and C-288. The grain, straw and biological yield of barley were observed higher under C-83 clone. The soil pH and EC deceased more under plantation of eucalyptus clones over control (sole crop). A considerable increase in soil organic carbon and available N, P and K content was also observed under eucalyptus based agri-silvicultural system than under control (devoid of trees).
