Profile Distribution of Phosphorus Fractions in Rice and Associated Non-Rice Soils under Different Pedogenic Development Stages of the Brahmaputra Valley of Assam Trishna Sarmah, Samiron Dutta, Ingudam Bhupenchandra, R.M. Karmakar, Danish Tamuly, Anshuman Bordoloi, Marami Dutta, Sweta Nanda Journal of the Indian Society of Soil Science, 2024 Profile distribution of different forms of phosphorus (P) was studied in rice and associated non-rice soils belong to Entisols, Inceptisols and Alfisols of the Brahmaputra Valley, Assam to assess the P availability and evaluate the relationship between P distribution and pedogenic development of the soils. The modified Hedley fractionation method was adopted for the purpose. The overall sequence of abundance for different P fractions of the soils based on averages of profile weighted mean was as: NaOH extracted organic P (167.0 mg kg-1) > NaOH extracted inorganic P (112.9 mg kg-1) > residual P (45.2 mg kg-1) > bicarbonate extracted organic P (33.1 mg kg-1) > dilute HCl extracted P (24.0 mg kg-1)> bicarbonate extracted inorganic P (23.7 mg kg-1) > concentrated HCl extracted organic P (20.7 mg kg-1) > concentrated HCl extracted inorganic P (18.2 mg kg-1) > resin P (5.8 mg kg-1). The organic P extracted by NaOH was emerged as the most dominant fraction in the studied soil and contribute 37.0% to the total sum of the P fractions. The distribution of P was mostly influenced by pedogenic development stages of the soils rather than land use system. The total inorganic P fractions showed an increasing trend from Entisols to Alfisols but total organic P decreased with the maturity of soils. The significant and positive relationship between labile P fractions (resin P, bicarbonate extracted organic and inorganic P) with other organic P fractions indicated a stable and consistent P supplying capacity of the soils.
Effect of Soil Nutrient Management on P transformation under Protected Cultivation Khalid Hussain, Muniza Sarfraz Indian Journal of Agricultural Research, 2021 Background: Phosphorus, an essential element, plays a central role in cell metabolism and reproduction. It is a structural component of energy transferring molecules (ATP, ADP and AMP), nucleic acids, coenzymes, phosphor-proteins, phospholipids and sugar phosphates. In soils, the P does not occur abundantly as nitrogen or potassium. Despite its importance, only a proportion (~ 0.1-1.0 %) of it is available for use by plants and microorganisms because phosphorous has poor solubility and gets fixed in soil. Many studies had been done regarding nutrient management of soil in various parts of the world, but limited study was done in India and in North-East India, it is relatively unexplored. Thus, the main aim of this experiment was to find out how nutrient management influencing P fractions under protected cultivation. Methods: The investigation area from which soil samples were collected i.e., Horticultural Farm, Assam Agricultural University, Jorhat-13, Assam. The study was carried out under protected poly house condition in the year 2017-18. The test crop was Capsicum (Capsicum annum var. Swarna). The design of the experiment was Split-Split plot technique. Random soil samples were collected from different treatments under protected cultivation at a depth of 0-15 cm. The soil samples were collected at two different stages of the crop viz., flowering and fruiting stages at 45 and 115 days after planting respectively. Result: The present study revealed that single factor effect of nitrogen (N), phosphorus (P) and potassium (K) had a significant effect on different forms of P The readily available P forms tend to increase in the fruiting stage while the iron bound phosphates registered a decrease. This implies that iron bound phosphate form predominantly controlled available P in acid soils under protected cultivation. The study indicates that iron bound P may be considered as slowly available labile P for fertilizer scheduling under protected cultivation. The present study also revealed that single factor effect of nitrogen(N) and phosphorus(P) had a significant effect on yield of capsicum. Among the various P fractions, Pi-water and Pi-Fe contribute more towards yield of capsicum.
Enrichment of maize grains with zinc through agronomic biofortification G.G. Kandali, N. Yadav, R.M. Karmakar, D. Tamuly Journal of the Indian Society of Soil Science, 2021 A field experiment was conducted at instructional-cum-research farm of Assam Agricultural University, Jorhat, Assam to enrich zinc (Zn) in grains of a hybrid maize variety (PAC 740) through soil application of Zn with six levels of ZnSO4.7H2O viz. 0, 20, 40, 60, 80 and 100 kg ha-1 with and without foliar spray of 0.5% ZnSO4.7H2O at tasseling stage. Highest grain yield (7.83 t ha-1) was recorded with 60 kg ZnSO4.7H2O (soil) + 0.5% foliar spray. Significant increase in grain yield over control was observed at 40 kg ZnSO4.7H2O and above. Foliar application of Zn though improved yield, but statistically had no effect on yield, plant height and number of grains per cob between graded doses of Zn with and without foliar application. However, grain Zn concentration and uptake were more effectively increased by Zn fertilization, especially with soil and foliar applications. Significantly highest grain Zn concentration (46.9 mg kg-1) and uptake of Zn (358.2 g ha-1) was observed with 100 kg ZnSO4.7H2O ha-1 (soil)+0.5% foliar application over control. Nitrogen and potassium concentration and uptake by grains increased with the increasing level of Zn but phosphorus concentration and uptake decreased. Agronomic efficiency and apparent recovery efficiency was found highest in the treatment with 60 kg ZnSO4.7H2O ha-1 (soil)+0.5% foliar application. Soluble protein increased significantly over control with 40 kg ZnSO4.7H2O ha-1 (7.41%) and above. Although, crude protein and starch content increased with the increase in Zn concentration, the effect was not significant with increasing dose of ZnSO4.7H2O.
Characterization and classification of some alluvium-derived rice and associated non-rice soils of Jorhat district of Assam Trishna Sarmah, Samiron Dutta, R.M. Karmakar, Danish Tamuly, Namita Dutta Journal of the Indian Society of Soil Science, 2019 A study was conducted to characterize and classify some traditional rice and associated non-rice soils of Jorhat district of Assam. Three locations (Borholla, Koronga and Alengmora) were selected for the purpose and alltogether six soil profiles, one each from rice and associated non-rice soils, were collected. The results showed only few differences in morphological, physical and chemical properties between the rice and associated non-rice soils. Soils were dark brown to brownish yellow in colour, sandy loam to clayey in texture and very strongly acidic to neutral in reaction. The organic carbon (OC) content was found to be higher in the surface horizons (10.3–18.1 g kg-1) as compared to the sub-surface horizons (1.2–15.5 g kg-1). Exchange acidity of the soils ranged from 0.50–3.25 cmol(p+)kg-1 and indicated dominance of exchangeable Al3+ (0.25–2.63 cmol(p+)kg-1). The CEC was invariably low (4.7–12.3 cmol(p+)kg-1). Rice soils of Borholla and Alengmora showed marginally higher pH than non-rice soils but OC exhibited an opposite trend. Exchangeable Al3+, exchange acidity and total potential acidity were slightly higher in rice soils of Borholla and Koronga than non-rice soils. The rice and associated non-rice soils of Borholla were qualified for Alfisols and classified as Oxyaquic Hapludalfs at subgroup level. Both rice and non-rice soils of Koronga and Alengmora were placed under Inceptisols and Entisols and classified as Oxyaquic Dystrudepts and Typic Udifluvents, respectively at subgroup level. An improvement in profile development was observed with the increase in the distance from the river Brahmaputra because of improvement in drainage condition and stability of landforms.
