39 Which condition is most important when selecting a field for sesame cultivation?

40 A farmer in a sesame-growing area wants a commonly recognized Indian sesame variety. Which option is suitable?

41 A germplasm expedition seeks wild diploid relatives representing the ancestral gene pools of cultivated groundnut, Arachis hypogaea. Which region should receive the highest priority?

42 A planner must select an Indian production zone where rainfed groundnut commonly encounters intermittent drought and receives monsoon rainfall concentrated within a short season. Which zone best fits this description?

43 Two groundnut cultivars produce the following pod yields and kernel characteristics: cultivar P: t/ha pods, shelling, kernel oil; cultivar Q: t/ha pods, shelling, kernel oil. Based only on oil yield per hectare, which conclusion is correct?

44 A groundnut crop shows vigorous foliage and abundant flowering, but many pegs fail to penetrate the soil and pods contain poorly filled kernels. The field has a compact surface crust and low exchangeable calcium in the pod zone. Which intervention most directly addresses both constraints?

45 A farmer in a short, drought-prone kharif season wants a groundnut growth habit that permits closer spacing, comparatively uniform pod maturity, and easier harvesting. Which varietal type is most appropriate?

46 Groundnut is planted at cm spacing with one seed per hill. Germination is , and an additional of the established plants are lost. Approximately how many plants per hectare remain?

47 A rainfed groundnut field can receive only one life-saving irrigation. Soil moisture is adequate through vegetative growth but a prolonged dry spell begins at flowering. At which stage would irrigation most effectively protect pod yield?

48 Which evidence combination most strongly supports East Asia as the primary region of soybean domestication?

49 A soybean cultivar performs well at one latitude but flowers prematurely when moved to a region with shorter day length, sharply reducing biomass and yield. Which trait most directly explains this geographical adaptation problem?

50 A soybean lot contains protein and oil. Processing recovers of the oil, while all protein remains in the defatted meal. From kg seed, approximately what quantities of recovered oil and protein in the meal are obtained?

51 After heavy monsoon rain, soybean plants in a level clay field become yellow despite adequate nitrogen, while plants on adjacent broad beds remain greener. Which mechanism best explains the difference?

52 Before replacing a locally adapted soybean variety with a high-yielding cultivar from a distant latitude, which varietal attributes require the closest joint evaluation?

53 Soybean is grown for the first time in a field without a history of the crop. The soil contains little effective soybean rhizobia, but seed inoculation is possible. Which nutrient strategy is most appropriate?

54 A soybean crop produces t/ha total above-ground dry matter and t/ha grain. If management increases dry matter by but harvest index falls from its original value to , what is the new grain yield?

55 Which origin pairing is most consistent with commonly accepted crop-history evidence?

56 A semi-arid district has erratic rainfall, deep well-drained soil, and a long frost-free season. Farmers need an oilseed capable of deeper rooting and greater drought endurance than sesame. Which crop-zone match is most defensible?

57 A processor compares sesame yielding t/ha with oil and castor yielding t/ha with oil. Extraction efficiencies are and , respectively. Which statement is correct?

58 Four fields receive intense rain shortly after sowing. In which field is sesame establishment most likely to decline even if seed viability is high?
