Abstract
The field experiment entitled, “Performance of clusterbean cultivars under different resource
conservation techniques” was conducted at Research Farm of CCS HAU Regional Research Station, Bawal
(Rewari), during kharif season of 2009-10. The main plot treatments consisted of four resource conservation
techniques (RCTs) viz. conventional tillage (CT), furrow irrigated raised bed system (FIRBS), zero tillage (ZT)
with 5% wheat residue (WR) and ZT with 30% WR; and three cultivars HG 563, HG 365 and HG 2-20 were
kept in sub-plots making twelve treatment combinations which were tested in split plot design with three
replications. Different RCTs had significant impact on growth, yield attributes and yield of clusterbean and also
on nutrient uptake by the crop. ZT 30% WR resulted into better growth and yield of all clusterbean cultivars.
Maximum gross return was under ZT 30% WR, however, net return ( 24630 ha-1) and B: C ratio (3.17) was
higher under ZT 5% WR. N, P and K uptake by various clusterbean cultivars was higher in HG 2-20. At crop
harvest, available N, P and K content in the soil was more under ZT 30% WR. Among three clusterbean
cultivars, HG 2-20 attained more growth and resulted into higher grain yield (1532 kg ha-1) closely followed by
HG 563 (1419 kg ha-1) and HG 365 (1208 kg ha-1). Protein and gum yields were also higher in HG 2-20. HG
2-20 resulted into maximum net return ( 21997 ha-1) and B: C ratio (2.07). Thus, HG 2-20 coupled with ZT 5%
WR was adjudged the most suited treatment combination for higher and economic yield. However, ZT 30% WR
is expected to be remunerative and sustainable on long-term basis provided farmers can afford to retain at least
30% of previous crop residue on soil surface.
