ThesisItem Open Access Establishment of minimum performance standard of prominent agricultural machinery based on test reports(CCSHAU, Hisar, 2019-09) Maan Singh; Jain, MukeshA study was conducted to establish minimum performance standard (MPS) of selected agricultural machinery based on test reports collected from Deptt. of FMPE, COAE&T and FMT&TI, Hisar. The data was collected for the analysis and MPS was formulated by frequency distribution using MS-Excel Add-In. To determine the mean of individual parameter, corresponding values of the most occurring frequency (about 50 % of the frequency) was only considered. The MPS suggested for tillage machinery are 6.50 cm, 14 cm, 0.23 ha h-1, 76 %, 3.0 l h-1, 77 %, 11 kW and 817 mm for min. depth of cut, min. depth of puddle, min. area covered per metre of working width, min. field efficiency, max. fuel consumption per metre of working width, min. puddling index, max. PTO power requirement per metre of working width and nominal closed length of drive shaft of rotavator; respectively. for disc harrow, 8 cm, 0.43 ha h-1, 70 %, 3.0 l h-1, 213 kg-f and 4.0 kW for min. depth of cut, min. area covered per metre of working width, min. field efficiency, max. fuel consumption per metre of working width, max. draft per metre working width and max. drawbar power per metre working width of disc harrow; respectively. for cultivator, 9 cm, 0.41 ha h-1, 75 %, 2.0 l h-1, 244 kg-f and 3.4 kW for min. depth of cut, min. area covered per metre working width, min. field efficiency, max. fuel consumption per metre working width, max. draft per metre working width and max. drawbar power per metre working width of cultivator, respectively. In sowing and planting machinery MPS suggested are 50 %, 6 & 8 cm, 6 & 8 cm, 5 & 10 mm, 0.12 %, 0.27 ha h-1, 71 %, 1.40 l h-1, 98 kg ha-1, 118 kg ha-1, 1.0 kW, 189 kg-f and ± 20 & ± 24 % for seeding uniformity, min. and max. depth of seed, min. and max. depth of fertilizer, min. and max. seed spacing, max. mechanical damage of seed, min. area covered per metre working width, min. field efficiency, max. fuel consumption per metre working width, min. seed rate, min. fertilizer rate, max .drawbar power per metre working width, max. draft per metre working width, max. variation in dropping of seed and fertilizer of zero till seed cum fertilizer drill, respectively and 8.5 & 9.0 cm, 8.5 & 10 cm, 30 & 40 cm, 0.24 ha h-1, 64 %, 0.60 l h-1, 1.7 kg ha-1, 53.8 kg ha-1, 0.80 kW, 71 kg-f and ± 0.60 & ± 0.80 % for min. and max. depth of seed, min. and max. depth of fertilizer, min. and max. seed to seed distance, min. area covered per metre working width, min. field efficiency, max. fuel consumption per metre of working width, min. seed rate, min. fertilizer rate, max. power drawbar per metre of working width, max. draft per metre of working width and max. variation in dropping of seed and fertilizer of Bt. cotton planter. Similarly, MPS have been suggested for other equipments/machinery like plant protection equipments, tractor operated VCR, straw reaper, paddy thresher and maize thresher. The MPS also includes safety and other requirements, material of construction etc. to be complied on.ThesisItem Open Access Screening of Wheat Genotypes for Morphophysiological Characters in Bread Wheat (Triticum aestivum L.)(2024-06-15) Maan Singh; Dr R K YadavThesisItem Open Access Studies on the biology and population dynamics of rice leaffolder, cnaphalocrocis medinalis guenee(CCSHAU, 2007) Zood, Ankit; Maan SinghPopulation dynamics and biology of rice leaffolder were carried out in the field, laboratory and screen-house at CCS Haryana Agricultural University, rice research station, Kaul (Kaithal) during Kharif 2006. The population of rice leaffolder fluctuated in different periods during the season The maximum number of eggs, larvae and pupae were observed during the 35th week ( i.e 4th week of August), 36th week ( i.e 1st week September) and 37th week ( i.e 2nd week of September),respectively. Indicating that maximum population predominated in September-October. Larval and pupal parasitism was good during the season while egg parasitism was almost nil. Apanteles sp. and Cotesia sp. were observed the dominating larval parasitoid. While Brachymeria sp. and Xanthopimpla flavolineata were dominating pupal parasitoids. A spider Lycosa sp. was observed to predate upon larvae and pupae of leaf folder. Total eggs with rainfall and parasitoids shows negative correlation. When total larval population correlated with biotic and abiotic factors it shows positive correlation with maximum temperature and sunshine hours while negative correlation with other factors. Pupal population exhibits positive correlation with maximum temperature, sunshine hours and predators only. The eggs were laid singly or in clusters of two to four maximum (48.20%) on lower surface of leaf followed by upper surface (32.95%). The Incubation period was 5.32 ±o.02 days and hatchability ranging from 55.31-77.73 per cent. Full grown larvae measured 15.59 ± 0.24 mm in length and 1.22 ± 0.22 mm in breadth with 1.11 ± 0.03 mm length and 1.22 ± 0.24 mm breadth in head capsule. Female pupae were longer in length than male pupae. The leaffolder completed its post-embryonic development in 30.34 ± 0.48 days (males) 31.16 ± 0.51 days(females) and passed through five instars with 56.66 ± 1.70 per cent (larval survival), 51.32 ± 0.80 (per cent pupation) and 89.60 ± 1.29 per cent (moth emergence). The mean larval and pupal period (male and female) was 22.10 ± 0.39 and 6.86 ± 0.06, 7.64 ± 0.09 days, respectively. Preoviposition, oviposition and post-oviposition period were 1.7 ± 0.05, 4.5 ± 0.03 and 2.4 ± .03 days, respectively. The average longevity of male and female was 3.4 ± 0.06 and 8.7 ± .05 days, respectively. The average fecundity was 100.6 ± 8.6 egg/female with 70.74 ± 2.7 per cent hatching. Sex ratio showed pre pondrance of male (1:0.91).The adult male was short lived 3.4±0.06 days as compared to female 8.7±0.05 days. The rice leaffolder passed through three generation during kharif season.
