Pigeonpea (Cajanus
cajan L. Mill sp.) is an important food legume of the semi-arid tropics of
Asia and Africa. It occupies a prominent place in Indian rainfed agriculture.
Enhancing the productivity of the crop assumes specific significance in India,
mainly to combat protein malnutrition, as it is the main source of protein to
the predominant vegetarian population. During recent times, organic agriculture
has emerged as an economically viable option of farming because of the growing
demand for organic products worldwide. This study was conducted to study the
effect of intercropping system and nutrient management through organic sources
on yield attributes and yield of pigeonpea crop (Cajanus cajan L.) under south Gujarat conditions. An experiment was
conducted for two consecutive years at Rambhas Farm, Hill Millet Research
Station, Navsari Agricultural University, Waghai, Dangs, Gujarat, during kharif
season of 2022-23 and 2023-24. The
experiment was laid out in randomised block design with factorial concept
having two factors with twenty-four treatment combinations and three
replications. Yield attributes, viz., number of pods per plant, pod length and
number of seeds per pod of pigeonpea were recorded significantly higher under
treatment I4 (sole pigeonpea) during both years and in pooled analysis, which
was at par with treatment I3 (pigeonpea + drilled paddy). Significantly higher
seed yield and stalk yield of pigeonpea were recorded in sole pigeonpea (I4)
during both years of study and in pooled analysis. The higher stalk yield under
sole pigeonpea might be due to lack of competition because of intercrops, as
the plants have to face neither nutrient nor moisture stress conditions in sole
cropping, which reflects in improvement of growth and yield attributes of
pigeonpea crop and finally in terms of stalk yield. Significantly higher number
of pods per plant, pod length and number of seeds per pod, seed yield and stalk
yield of pigeonpea were noted with application of 10 t/ha FYM + Three spray of
2 % Enrich banana pseudostem sap (N4) which remained statistically at par with
treatment N6 (5 t/ha vermicompost + Three spray of 2 % Enrich banana pseudostem
sap) and N1 (10 t/ha FYM) during both the years and in pooled analysis. From
the findings, it can be concluded that Drilled paddy or little millet as an
intercrop in kharif pigeonpea at a 1:2 row proportion is found more feasible
for higher yield and profit than finger millet under south Gujarat conditions.
Additionally, the application of farmyard manure along with multiple sprays of
enriched banana pseudostem sap to the pigeonpea–nutri-cereal intercropping
system (1:2 row ratio) can enhance profitability and yield
