ABSTRACT
The present investigations entitled “Standardization of fertilizer doses for pea varieties grown under
peach based agroforestry system” was carried out at the experimental field of Department of Silviculture &
Agroforestry, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (H P) during 2012-2013.
The study was undertaken with the two objectives (a) to study the effect of different doses of inorganic
fertilizers and Rhizobium inoculation on growth and yield of pea varieties and physiochemical properties of soil.
(b) to identify the suitable pea variety to be grown under peach based agroforestry system. The experiment was
laid out in randomizes block design (factorial) comprising of peach var. nectarina planted at a distance of 9m x
4m and open field condition, under which three varieties of pea (Solan Nirog, Azad P 1 and PB 89) were grown
with five doses of inorganic fertilizers + Rhizobium inoculated seeds (RIS) viz., T1 (100% recommended dose
of NPK + RIS), T2 (80% NPK + RIS), T3 (60% NPK + RIS), T4 (40% NPK + RIS) and T5 (control). The plot
size was 4m x 2m and spacing of 60 cm x 7.5 cm was maintained for pea crop. The observation were recorded
on growth and yield parameters of pea and soil chemical properties. The seeds were sown in 1st December 2012.
All the growth and yield attributes of pea were significantly influenced by different doses of inorganic fertilizers
+ RIS except node number bearing first flower. Treatment T1 showed best results in most of the growth and
yield attributes of pea crop viz., plant height (cm), number of pods plant-1, number of grains pod-1, pod length
(cm), pod breadth (cm), 100 grain weight (g), shelling percentage (%), total biomasss production (g) and
number of nodules per plant. There were no effect of planting conditions with regard to all the growth and yield
attributes of pea as well as chemical properties of soil. Various soil chemical parameters viz., EC, OC, available
N, available P showed maximum value in treatment T1(100% RD NPK + RIS). However, available K was
reported maximum in treatments T4 (40% NP, 100% K + RIS). Variety PB 89 exhibited maximum value in most
of the growth and yield attributes of pea except plant height, node number bearing first flower and shelling
percentage. From the present investigation, it can be concluded that pea variety PB 89 can be successfully
grown under peach based agroforestry system without much reduction in yield as compared to sole cropping and
for obtaining maximum yield, seed should be inoculated with Rhizobium along with application of 100% RD
NPK. This diversified practice can be a viable option for boosting the economy of farming community.
