    Varietal evaluation of guava for morpho-physiological traits under semi-arid condition of Haryana
    (CCSHAU, Hisar, 2019) Parveen; Sharma, Jeet Ram
    A field experiment was conducted at the guava demonstration centre, Bhuna (Fatehabad), Haryana. Fifteen varieties having a wide range of variability in growth, flowering, fruit, and qualitative traits were studied in Randomized Block Design. Results showed that among the varieties, Allahabad Safeda showed early initiation and ending of flower in rainy season, while, in winter season it was showed by Hisar Safeda. Late flowering initiation and ending was showed by Pant Parbhat in rainy season, whereas, in winter season scattering flower is continous in Lalit, KG Guava, Pant Parbhat and Shweta varieties of guava. KG Guava had the maximum plant height, plant spread, foliage density, fruit length, fruit diameter (width) and fruit weight, while, minimum plant height and spread was found in Banarsi Surkha. Minimun leaf internodes distance was found in KG Guava. Pant Parbhat had maximum internodes distance in branch during both the season and minimum was showed by Barf Khana. Allahabad Safeda had minimum fruit length, fruit diameter (width) and fruit weight. Maximum TSS, TSS:Acid ratios and minimum titratable acidity was observed in Hisar Safead. L-49 had maximum ascorbic acid content during both the seasons. Phyllotaxy in selected varieties found from decussate to opposite type. Leaf shape varied from elliptical, oblong, ovate and trullate type in selected varieties. Mature leaf color varied from green, light green and dark green. In case of fruit shape and surface maximum varieties showed round type of fruit shape and smooth fruit surface, respectively. Pulp color in selected varieties varied from white, creamy-white to pink. In case of fruit skin color, maximum varieties showed yellowish-green color of fruit skin.

    Energetics and techno-economic feasibility of paddy straw management technologies
    (CCSHAU, 2018) Parveen; Jain, Mukesh
    Paddy straw management using different combinations of machinery i.e. T1 = Combine harvester with SMS (CSMS) + Zero till drill, T2 = CSMS + Spatial till drill, T3 = CSMS + Happy seeder, T4 = CSMS + Reversible mould board plough + Rotavator + Seed drill, T5 = CSMS + Rotavator (2 pass) + Seed drill (SD), T6 = CSMS + Disc harrow (3 pass) + Planker + SD, T7 = CSMS + Rotavator + Manual broadcasting + Rotavator, T8 = Traditional combine (TC) + Stubble shaver + Straw baler + Disc harrow (2 pass) + Planker + SD, T9 = TC + Stubble shaver + Hay Rake + Straw baler + Disc harrow (2 pass) + Planker + SD, T10 = TC + Traditional straw removing method + Disc harrow (2 pass) + Planker + SD with the objective of quantifying the energy requirement and to evaluate techno-economic feasibility. From the experiments, it is concluded that the specific energy consumption and unit cost of operation were in the range of 25 to 28 MJ q-1 and 63 to 68 Rs. q-1 for treatment T1, T2 and T3 respectively. Under the treatment T10, the specific energy consumption and unit cost of operation were 38 MJ q-1 and 74 MJ q-1, respectively. Under the treatment T4, T6, T7, and T8 the specific energy consumption was in the range of 50 MJ q-1 and unit cost of operation was in the range of 112-135 Rs. q-1. Highest specific energy consumption (58.15 MJ q-1) in treatment T5 and highest unit cost of operation (140.52 Rs. q-1) was found in treatment T9.
