Example 2: An experiment was conducted to study the hybrid seed production of bottle gourd (Lagenaria siceraria (Mol) Standl) Cv. Pusa hybrid-3 under open field conditions during Kharif-2005 at Indian Agricultural Research  Institute, New Delhi. The main aim of the  investigation was to compare the effects of hand pollination {the male flowers also pinched from the seed parent before the anthesis regularly. The female buds are covered with butter paper bag which contain 5-6 tiny hole to felicitate the ventilation and to avoid the built up of high  temperature in  size the butter paper bag.  The butter paper bag is clipped/stippled.  On the same day the male bud at pollen parent (male plant)  are  also covered   with butter paper bag.  On the next  day the male bud are removed  and the  anthers  are rubbed gently over the all three lobes. The female flower is again covered with butter paper bag and label is placed over the peduncle of pollinated female flower (plate 4, 5, 6 &7).  The  pollination is  performed  at noon  (1-3pm)}on  hybrid seed  production in bottle  gourd under  open field and poly house conditions.  The data were collected on 10  randomly selected  plants from  each of open field and polyhouse conditions. The data were collected  on total number of male flowers per  plant, number of fruit set for the period of 45 days, fruit weight (kg), fruit length in cm, seed yield per plant (g) and seed length (cm).

{Here 2 denotes hand pollination in open field conditions and 3 denotes hand pollination in polyhouse conditions}

1. Test whether hand pollination under open field conditions and polyhouse conditions are equally effective or are significantly different.
