Assessment of Influence of Soil-site Characteristics on Soybean Productivity in Swell-shrinks and Associated Soils of Semi-arid Tropics

Indian Journal of Dryland Agricultural Research and Development (2008)

G. Ravindra Chary K.P.R. Vittal G. R. Maruthi Sankar V. Ramamurthy R. A. Sharma

A study has been conducted in swell-shrink and associated soils to assess the influence of soil-site characteristics on rainfed soybean yield attained with low and improved management practices across four microwatersheds viz., Varkhed and Panubali in Maharashtra; and Jaitpura and Khuj in Madhya Pradesh. There was a wide spatial variability of soil-site characteristics of swell-shrink and associated soils viz., Typic Ustorthents, Typic Haplustepts, Vertic Haplustepts, Typic Haplusterts within and across four microwatersheds. In general, soybean productivity was high in Typic Haplusterts followed by Vertic Haplustepts while it was low with Typic Ustorthents under both management levels. Based on correlation and regression analysis, the most important soil-site characteristics influencing soybean yield were found to be drainage among site characteristics; soil depth and AWC among soil physical, and OC and CEC among soil chemical characteristics. The study indicated that for improving the productivity of rainfed soybean cultivated in swell-shrink and associated soils, soil depth, AWC, OC and CEC with ideal conditions were essential for attaining a yield level of 7–8 q ha−1 with low management, while only two soil characteristics viz., soil depth and AWC were found important for attaining a yield level of 12–14 q ha−1 with improved management.

Effect of planting materials, fertilizers and microsite improvement on yield and quality of henna (Lawsonia inermis) in Alfisols of semi-arid regions

The Indian Journal of Agricultural Sciences (2007)

G. Pratibha G. R. Korwar D. Palanikumar Vaishnavi Jois

A field study was conducted for 6 years (1998-2004) at Hyderabad to evaluate the influence of planting materials, microsite improvement and fertilizers on productivity, lawsone content and economic returns of henna (Lawsonia inermis L). The leaf yield and quality were influenced by different treatments. During rainy season the yield increase in cuttings over seedlings was 100, 50.7, 37.7, 63.8, 29.6, 61.3 % during 1998, 1999, 2000, 2001, 2002 and 2003 respectively. Whereas the increase in post-rainy season yields were 360, 26.7,100, 49.3, 41.7, and 60.7 % during 1998, 1999, 2000, 2001, 2002 and 2003 respectively. This indicates that the increase in yields was more in high rainfall years (1998, 2001, 2003) compared with the low rainfall years (1999,2000, 2002). Significant increase in leaf yields was observed with microsite improvement over the no microsite improvement during low rainfall years. The treatments having seedlings, microsite improvement and fertilizer application recorded significantly higher lawsone content. At the end of 9 years cuttings recorded 73, 112, 73 % higher gross, net monetary returns and B: C ratio respectively over the seedlings. Microsite improvement improved gross and net returns by Rs 53 150 and Rs 43 425 compared with the no microsite improvement. The comparison of regression coefficients has shown that, the rate of increase in leaf yield with rainfall differed significantly between the two planting materials and microsite improvement, indicating that seedlings are more drought tolerant than the cuttings. The microsite improvement helps in increase of yields during low rainfall years.

Managing Soil Organic Matter under Dryland Farming Systems for Climate Change Adaptation and Sustaining Agriculture Productivity

CRC Press eBooks (2021)

Ch Srinivasarao Sumanta Kundu SS Rakesh Ch. S. Rama Lakshmi G. Ranjith Kumar

Soil erosion and land degradation are led by frequent floods and droughts which are the prime reasons of low productivity in land areas. Poor soil conservation practices, lack of technology transfer, and low-yielding crop varieties are further degrading soil fertility status of land under rainfed farming. In general, crops grown on rainfed soils are highly prone to drought stress and multi-nutrient deficiencies, because these are coarse-textured soils of low water and nutrient retention capacity, low soil organic matter (SOM) content with less aggregate stability. Mono-cropping of staple crops and mining of essential nutrients from soil have caused nutrient imbalance and deterioration of soil quality. Degrading soils, accelerating soil erosion, depleting soil fertility, decreasing soil moisture-holding capacity, depleting ground water table, and increasing multiple nutrient deficiencies lead to low crop yields and perpetuate rural poverty.

Effect of tillage induced physical edaphic properties in relation to crops after puddled rice (Oryza sativa)

The Indian Journal of Agricultural Sciences (1998)

G. Pratibha K. Gopalakrishna Pillai V. Satyanarayana

A field experiment was conducled on a sandy soil to study the effect of tillage methods and irrigated crops on physical properties of soil after wet-season puddled rice (Oryza sativa L.) during 1990 and 1991. The upland crops grown in sequence with rice were blackgram (Phaseolus mungo L.), groundnut (Arachis hypogaea L.), castor (Ricinus communius L.) and sunflower (Helianthus annuus L.), Land preparation with tractor-drawn mouldboard plough once followed by rotovator tWice, and ploughing once with tractor-drawn mouldboard plough + disc harrowing recorded lower bulk density (1.31,1.33 g/cc), higher porosity, infitration rate and hydraulic conductivity (7.3 cm/hr). Groundnut recorded lower bulk density, higher hydraulic conductivity and infiltration rale compared with other crops.
