Effect of Paddy Straw mulching and Tillage on Growth and Yield of Pea
(Pisum sativum L.)
V. Akashe Zhimomi, Bendangjungla and Peiwang
A field experiment was conducted during the rabi season 2021-22 at farmers field, NICRA
village, Mon district, Nagaland to study the effect of paddy straw mulching and tillage on growth
and yield of field pea (Pisum sativum L.). Aman, is a new pea variety introduced for the district
and has become a staple crop. The crop is generally sown during the last week of October after
the harvest of wet rice cultivation (WRC). The result showed that maximum plant height, no. of
branches per plant, no. of pods per plant, no. of seeds per pod, test weight and soil moisture
content were obtained from paddy straw mulch with minimum tillage. The highest net income
and benefit cost ratio was obtained from paddy straw mulch with minimum tillage.

All India Coordinated Research Project on Dryland Agriculture, Solapur Maharashtra. 413 002
An experiment was conducted at Dry Farming Research Station, Zonal Agricultural Research
Station, Mulegaon farm Solapur during year 2020-21 to study the effect of tillage and residue
management on yield of blackgram – rabi sorghum sequence grown on Inceptisol under rainfed
condition. The main tillage management treatments were i) Conventional tillage (CT) ii)
Reduced tillage (RT) and iii) Zero tillage (ZT) with different residue management sub treatments
viz. S1= Kharif fallow (No retention of crop residue) + RDF (50 :25: 25 kg/ha N:P2O5:K2O) for
rabi sorghum, S2 = Harvest of black gram above ground level at flowering stage for surface
cover as a green lopping’s (root + crop residue)+ 0:50 Kg/ha N: P2O5 + PSB + Rhizobium seed
treatment to black gram and 37.5:0:25 Kg/ha N : P2O5 : K2O + Acetobacter + PSB seed
treatment for rabi sorghum and S3= Harvesting of black gram above ground level for grain
(Root biomass retained in soil) + 19:37.5 Kg/ha N:P2O5 to black gram + PSB + Rhizobium seed
treatment and 37.5:19:25 Kg/ha N:P2O5:K2O to rabi sorghum + PSB + Acetobacter seed
treatment.
