| Summary, etc | A field experiment was conducted at the Water Management field, ICAR Research Complex for NEH Region, Umiam, during 2009- l0 on Assessment of Water Efficient Cropping Systems for Rainfed Terraced Situation of Meghalaya. The experiment consisted of two tillage practices as main plots treatments- conventional tillage (CT) and conservation tillage (CST), and eight cropping sequences (4 cropping systems) as sub plot treatments (CS), viz, Maize- Toria (CS I), Maize-Pea (CS2), Rice -Toria (CS3), Rice-Pea (CS4), Ricebean-Toria (CS5), Ricebean-Pea (CS6), Soybean-Toria (CS7) and Soybean-Pea (CSS). The results indicated that conservation tillage recorded significantly higher profile soil moisture content, relative leaf water content, nutrient uptake and water use efficiency (WUE) as compared to conventional tillage. Soil organic carbon (SOC), available NPK, dehydrogenase activity and soil microbial biomass carbon were significantly higher in CST as compared to CT. Overall productivity of crops under CST in terms of grain yield were 25% and 27% higher, while in term of maize equivalent yield, they were 24% and 27% higher as compared to CT for kharif and rabi crops, respectively. The net return and B:C ratio were also higher under CST as compared to CT. At harvest of kharif crops, soil profile moisture was highest under soybean. At sowing of rabi crops, pea and toria succeeded maize recorded the highest soil moisture under conservation tillage. Soil profile moisture had never depleted below 50% of the soil moisture at field capacity under conservation tillage in all cropping sequences involving toria except ricebean-toria. Among kharif crops, N, P and K uptake were maximum in soybean, maize and rice, respectively. While for rabi crops, maximum N and K uptake was recorded in pea of rice-pea sequence and maximum P uptake in toria of maize-toria. Highest WUE was recorded in maize-toria sequence (23.9 kg ha��mm��) followed by maize-pea (19.9 kg ha��mm��). The SOC, soil available N, SMBC, and DHA were highest in soybean-pea sequence. The system productivity in term of MEY was highest in soybean-pea sequence (7.14 t ha��) followed by rice-pea (6.4 t ha��). Soybean-pea sequence recorded highest net return and B:C ratio of 2.9 and 2.4 in CST and CT, respectively. Therefore, from WUE and soil moisture utilization point of view, maize-toria sequence found to be most efficient. Whereas, considering soil health and income soybean-pea sequence was found most efficient. |
