Not AvailableConservation agriculture (CA) is being advocated as an alternative to conventional tillage based systems, as it not
only holds the potential to enhance soil biological properties, but could also sustain production in the long-run.
The impact of long-term tillage and nutrient management on soil biological properties, crops performance, yield
and returns were evaluated under maize-mustard rotation. Three tillage practices viz. zero tilled flatbed (ZTFB),
permanent bed (PNB) and conventional tillage (CT) along with three nutrient management practices; farmer’s
fertilizer practices (FFP), recommended dose of fertilization (RDF) and nutrient expert assisted: site-specific
nutrient management (NE®) were tested under the field conditions for six years (2013–2019). ZTFB produced
the highest average maize grain yield, which was statistically similar to PNB; however it was 28.4% greater than
CT. NE® and RDF recorded 27.4% and 24.8% higher yield over FFP, respectively. Similarly, ZTFB and PNB
produced 8.0% greater mustard seed yield than CT, while NE® and RDF had 23.5% and 22.3% greater seed yield
compared to FFP. Average of six years indicates, ZTFB and PNB produced 9.7% and 8.9% greater maize grain
equivalent yield (MGEY) than CT. Furthermore, NE® and RDF had similar MGEY, but 24.9% and 23% greater
than FFP. ZTFB and PNB gave the maximum economic benefits in comparison to CT plots. CT was 18.7% and
19.3% costlier than PNB and ZTFB, while RDF was more expensive than NE® and FFP. Plots under ZTFB and PNB
had 13.9% and 17.8% (0.0 0.15 m soil profile) and 14.6% and 12.5% (0.16 0.30 m soil profile) greater soil
organic carbon (SOC) than CT plots. These practices also had significant (p<0.05) positive impact on soil biological
properties, such as, soil microbial biomass carbon (SMBC), dehydrogenase (DH), alkaline phosphatase
(AP) and urease (UA) activities. In 0.0 0.15 m soil layer, NE® had greater values for SOC and SMBC than FFP,
but not significantly different to RDF. This study clearly demonstrated that the adoption of conservation tillage
(ZTFB / PNB) coupled with NE® and RDF in maize-mustard rotation would definitely improve system MGEY, net
returns and soil biological properties in semi-arid regions of the north-west India.Not Availabl
Apple Fruit Quality Identification using Clustering
An apples a day keeps doctor away" this proverb gives us important of apple in our healthy life. Apples fruit is consist of plenty of nutrition's therefore, doctors are always prefer to advice to eat the apple in most of the diseases. Hence, there is a huge demand of apples in market. To fulfill this demands suppliers need to provide the good quality fruit. There is a need of quality fruits in market. In this work studied various types of apples quality by using clustering approach. Comparative analysis is performed and given results are much better as compare to earlier work
