Abstract
ABSTRACT
The study was carried out in Kangra and Sirmour districts of Himachal Pradesh with special reference
to comparison of different sample allocation methods in combination with various stratification rules for
determination of optimum strata boundaries. For this purpose, four methods of construction of strata
boundaries viz., equalization of strata total, equalization of cum. , equalization of cum. {r(y)+f(y)} and
equalization of cum. rules were used and it was observed that variance term worked out to be least in
Neyman allocation and hence this allocation method was retained for further investigation. The critical
examining of the results also revealed that for varying sample size, equalization of cum. provided the
least variance, therefore, the study inferred that sampling methodology for estimation, “Statistical investigations
on kinnow Mandarin (Citrus reticulata Blenco.) production in Himachal Pradesh” should be in conjunction with
cum. can be used for estimation of kinnow production. To assess the relative contribution of various
morphological characters in increasing the kinnow yield, 104 trees from location-1 and 96 trees from location -2
were randomly selected in the year 2014-15. F-test suggested that there was significant variation among all the
characters between these two locations except fruit weight and LD ratio. It was also observed that number of
flowers per branch, number of fruits per branch, plant girth and fruit weight contributes significantly towards the
kinnow yield. In relation to the socio- economic status of kinnow orchardists, it was observed that the
contribution of fruit crops towards the gross farm income had shown an increasing trend, while the contribution
of field crops had shown a declining trend with the increase in farm size. At overall level, fruits crop accounted
for 62.68 percent while field crops accounted only 37.32 percent of the total gross farm income. In relation to
the price spread of kinnow under different marketing channels in the Himachal Pradesh indicated that
producers’ share in consumers’ rupee was highest in channel-IV (81%), followed by channel-III (51%) and
channel-I (43%), therefore, the marketing efficiency was found maximum (4.35) when farmers sold their
produce directly to consumers.
