“…Rice panicles grew consistently with fertility levels when plants received higher nourishment (Choudhary and Suri, 2014). Similar to observation by Borah et al (2016) crop receiving INM produced higher number of panicles than those obtained with the other treatments (during both the years), whereas the lowest was recorded with control. Slow release and continuous supply of nutrients in balanced amounts during different growth phases, ensured by the application of organic and conventional fertilizers led to the production of more panicles with more fertile grains and promoted better plant growth (Singh et al, 2018).…”

“…Shifting cultivation is the most prevalent form of agriculture in North eastern part of the country, including the state of Meghalaya. Direct-seeded upland paddy forms the major crop in jhum cultivation (Borah et al, 2016). However, the production is constrained mainly due to deficiency in soil nutrients and moisture resulting in a poor socio-economic condition of these rainfed farmers.…”

Background: Replenishing the lost nutrients through the use of various soil amendments is vital in order to maintain soil fertility for sustained productivity in jhumlnd. Integrated Nutrient Management, can boost the upland rice productivity in jhumland by building up the lost soil nutrients. Methods: The study was conducted to evaluate the impact of integrated nutrient management on growth and yield of upland paddy (Oryza sativa L.) in Lai-Lad, Jirang Block of Ri-Bhoi District, Meghalaya, India; during 2019 and 2020. Randomised block design with 12 treatments was applied for the trial with 3 replications. Result: Application of 100% recommended doses of fertilizers + farmyard manure + Azospirillum lipoferum + phosphorus solubilizing bacteria + potassium mobilising bacteria + Glomus + zinc solubilizing bacteria (T10) significantly increased plant growth in both years of cultivation. Grain yield, harvest index and benefit cost ratio of upland paddy were at par among the treatments and were higher in 2nd cropping year. Integrated nutrient management could increase the growth characters, maintain sustained yield and economic profitability of upland paddy in hilly terrains of north-east India, under jhum cultivation.

“…In general, soil is formed by weathering process of rocks and minerals that produce soil particles with sizes vary from rough as sand, and smooth as clay [19]. In edaphology, soil serves as a venue for supporting the development of root growth of plants as well as water, air supply needs [16,20], and nutrient supplies [21].…”

Bioavailability of Silica on Paddy Soils with Various Land Aging in Musi Rawas South Sumatera of Indonesia

et al. 2018

View full text Add to dashboard Cite

Utilization of intensive paddy soils for rice cultivation are main causing deficiency of soil silica (Si) due to high concentration Si adsorption in soils with values varies between 230 up to 470 kg ha-1. The soil silica availability on agriculture lands in Indonesia varies from 203 to 982 mg kg-1, and the paddy soils in Java and Sumatra have shown a decreasing the silica between 11% to 20% in the last three decades, resulting in declining paddy soils productivity. This study was aimed to investigate the availability of silica in the paddy soils distributed in Musi Rawas. The study was scheduled from May to November 2016 using survey methods, and soil analyzes performed in laboratory of SEAMEO Biotrop Bogor.The results showed that availability of silica in wetland has reduced by 50% in two decades, and meanwhile the availability of silica in irrigated soils about 7.5 times lower compared to rainfed soils. The silica availability of irrigated soils from wetland had 4.5 times higher than the irrigated soils of dryland. Furthermore, silica contained in rice husk had also decreased down to 74.5%, resulting in the decreasing of grain production due to a decrease in availability of silica in soil.

A field study was conducted at the Instructional Farm, Odisha University of Agriculture and Technology, Bhubaneswar, Odisha, India, on exploring productivity and soil quality of aromatic rice‐green gram system by dual influence of organic and inorganic sources of nutrients. Among integrated nutrient management practices, 50% NPK + 50% recommended dose of nitrogen (RDN)‐farm yard manure (FYM) to rice produced the highest grain yield (3875 kg ha−1) followed by 75% NPK+ green manure (GM; 3489 kg ha−1). Likewise, residual effect of 50% NPK + 50% RDN‐FYM to rice and application of 75% NPK+ Rhizobium+ phosphate solubilizing bacteria (PSB) to green gram produced the highest seed yield of green gram (812 kg ha−1).Combined application of 50% NPK+ 50% RDN− FYM to rice and 75% NPK + Rhizobium+ PSB to green gram resulted in significantly (p = 0.05) higher system rice equivalent yield (6521 kg ha−1) and production efficiency (31.2 kg ha−1 day−1) while increasing the nutrient uptake of short grain aromatic rice‐green gram system. The highest PFPN (132.7 ± 12.4 kg kg−1) and nitrogen uptake efficiency (0.73 ± 0.06 kg kg−1) were also recorded due to the application of 50% NPK+ 50% RDN‐FYM to rice and 75% NPK + Rhizobium + PSB to green gram (99.0 ± 26.3 kg kg−1, 0.61 ± 0.01 kg kg−1, 1.32 ± 0.40, and 19.5 ± 2.9, respectively). Application of 75% NPK+ GM to rice and 75% NPK + Rhizobium + PSB to green gram significantly (p = 0.05) increased soil organic carbon, available N, P, K, Fe, Mn, Zn, and Cu as well as microbial status of soil.
