28 Young arecanut seedlings develop scorched leaves during hot summer afternoons. Which management practice is most appropriate?

29 A farmer wants to use both the vertical space and shaded ground layer in a mature arecanut garden. Which intercrop combination is most suitable?

30 In an arecanut garden on sloping land, fertilizer is being lost with runoff. Which change would best improve nutrient-use efficiency?

31 Oil palms are planted at 9 m spacing in an equilateral triangular system. Using an area per palm of , what is the approximate population per hectare?

32 A breeder crosses thick-shelled dura palms with shell-less pisifera palms. Which commercial fruit type is expected in the progeny?

33 A harvester must decide whether an oil palm bunch has reached harvest maturity. Which field indicator is the most reliable?

34 An oil palm block has abundant flowering but poor fruit set because natural pollinator activity is low. Which intervention directly addresses the problem?

35 Fresh fruit bunches are harvested at the correct stage but remain in the field for several days before processing. What is the most likely consequence?

36 A palmyrah orchard uses square planting at m. If 8% of the planting area is occupied by roads and channels, approximately how many palms can be planted per hectare?

37 Palmyrah seedlings are expected to produce males and females in approximately equal proportions. How many seedlings should be raised to obtain about 90 female palms?

38 Why is direct sowing at the permanent site often preferred for palmyrah establishment?

39 Freshly collected palmyrah sap ferments rapidly before it reaches the processing unit. Which practice is most effective for preserving it as a non-fermented beverage?

40 A producer wants to market the soft, translucent edible kernels commonly called ice apple or nungu. At which stage should the fruits be harvested?

41 A coconut plantation is established at m spacing. Ignoring border losses, how does a triangular system compare with a square system in plant population per hectare?

42 A farmer wants the precocity and yield advantage of a Tall × Dwarf coconut hybrid. Which planting-material strategy best preserves the intended hybrid performance?

43 The annual recommendation for an adult coconut palm is g N, g , and g . Approximately how much urea ( N), single superphosphate ( ), and muriate of potash ( ) are required per palm?

44 In a root-wilt-affected coconut tract, several palms show mild symptoms but still bear economically useful crops. Which production strategy is most appropriate?

45 A low-lying coconut field receives intense monsoon rainfall and retains water around the collar for several days. Which intervention most directly addresses the principal establishment risk?

46 Arecanut is planted at m in a square system. If drains and paths occupy of a one-hectare field, what is the closest effective plant population?

47 An arecanut recommendation supplies g N, g , and g per palm annually. Which combination most closely supplies these nutrients using urea ( N), SSP ( ), and MOP ( )?

48 A young arecanut garden uses banana as temporary shade. As the palms establish, the stand becomes excessively humid and spindle growth weakens. What is the best adjustment?

49 A plantation with a history of arecanut fruit rot experiences prolonged monsoon wetness. Which preventive programme best targets the epidemiology of the disease?

50 Which seed-nut collection plan offers the strongest basis for establishing a consistently productive arecanut plantation?

51 Oil-palm shell thickness is controlled by the major shell locus, where dura is , pisifera is , and tenera is . What progeny is expected from a true dura × true pisifera cross?

52 Oil palm is planted at m in an equilateral triangular arrangement. Ignoring boundary effects, what is the closest population per hectare?

53 A juvenile oil-palm block is being managed by ablation. Which transition best balances vegetative establishment with the start of commercial production?

54 An oil-palm estate harvests t of fresh fruit bunches per hectare. Potential crude palm-oil extraction is , but processing losses equal of the potential oil. What is the realized oil yield?

55 During harvest, one oil-palm bunch has attained the expected external colour but has no naturally detached fruits, whereas another has several fresh loose fruits beneath it. Which decision best protects oil quantity and quality?

56 A palmyrah improvement programme needs a predominantly female fruit orchard, but seedlings cannot be sexed reliably by ordinary juvenile morphology. Which strategy most directly reduces land wasted on unwanted males?
