The field experiments were conducted in farmer's field at five locations each of kole lands to study the effect of Magnesium (Mg) on yield and soil and plant nutrient status of rice during 2012-2013 and 2013-2014. The experiment was laid out in randomized block design with three replications. The treatments comprised of different levels of Mg viz; 40, 60, 80, 100, and 120 kg Magnesium sulphate(MgSO4)/ha along with control. Observations on growth characters yield attributes, yield and soil and plant nutrient status were recorded. The results revealed that application of 100 kg MgSO4 / ha recorded the maximum number of panicles/m2 (419.13), number of grains/panicle (109.36), thousand grain weight (28.78 g), grain (9.27 t/ha) and straw yield (9.04 t/ha) of rice. The results of pooled data on plant and soil nutrient status revealed that application of magnesium had a positive effect on nutrient content and availability of nutrients in soil. A significant positive correlation was also noticed between Mg application, yield attributes, yield and nutrient contents. The study concluded that application of 100 kg MgSO4 / ha was found to be optimum for correcting the deficiency in Mg deficient areas of kole lands under below sea level farming.

The Impact

The objective of this research was to find out the impact of zinc and organic fertilization on the productivity of rice. Two separate field experiments were conducted in a zinc deficient soil belonging to Typic Haplusterts and Typic Ustifluvents during Rabi 2011-2012. The results revealed that grain and straw yield was significantly enhanced on addition of zinc or organics or both over control in both soils. The rice yield increased with zinc doses and maximum yields was noticed with 5 mg Zn kg-1 and declined at 7.5 mg Zn kg-1. While addition of poultry manure recorded the maximum rice yields and was on par with vermicompost. However the highest grain yield (6103, 6344 kg ha-1) and straw yield (8369, 8459 kg ha-1) was recorded with application of 5 mg Zn kg-1 and poultry manure in Vertisol and Entisol respectively. Similarly, addition of 5.0 mg Zn kg-1 along with poultry manure @ 10 t ha-1 registered the highest growth traits it was comparable with vermicompost at same level of zinc, but superior to other treatment combination.

Field experiments were conducted during kharif, 2019 and kharif 2020 at S.V. Agricultural College Farm, Tirupati with three different times of sowing of little millet (second fortnight of June, first fortnight of July and second fortnight of July) in combination with three methods of establishment (Broadcasting, Sowing at 30 cm × 10 cm and transplanting 20 days old seedlings) and three nitrogen levels (20 kg N ha-1, 30 kg N ha-1 and 40 kg N ha-1). The results of the experiment revealed that among the three times of sowing, second fortnight of June sowings recorded higher grain yield, straw yield and nutrient uptake of little millet while lower values of these were obtained with July second fortnight sown crop during both the years of study. Transplanted little millet resulted in superior grain yield, straw yield and nutrient uptake compared to broadcasting and sowing at 30 cm × 10 cm. Maximum values of grain yield, straw yield and nutrient uptake were observed with application of 40 kg N ha-1 while minimum values of these parameters were obtained with application of 20 kg N ha-1. Transplanting little millet during second fortnight of June along with the application of 40 kg N ha-1 achieved higher grain and straw yield besides nutrient uptake by grain.

The present study was undertaken in the ongoing long-term experiment initiated during 2017 at experimental farm, College of Agriculture, Rajendranagar, Hyderabad. Soil samples collected from a depth of 0–15 cm was analysed for soil fertility parameters namely: available N, P and K. The results indicated that the different cropping systems had positive influence on improving the nutrient status (i.e., available N, P and K) significantly over the initial soil values (N: 112.20, P: 23.40 and K: 170.30 kg ha-1, respectively). These ten cropping systems were grouped in to five categories viz., pre-dominant cropping systems of the zone, ecological cropping systems, household nutritional security giving cropping systems, fodder security giving cropping systems and cropping systems involving high value crops. So that from each category, best cropping system can be identified and can be suggested to different integrated farming systems models. The maximum (221.60 and 221.57 kg ha-1) soil available nitrogen was obtained in Pigeon pea + Greengram (1:3) – Sesame after harvest of kharif and rabi, available phosphorus builds up was profound in Fodder maize – Lucerne (48.27 kg ha-1) and available K (207.63 kg ha-1) was higher in Rice –Maize cropping system after harvest. Fodder crops recorded significantly higher NPK uptake over other cropping systems.

Straw Yield

Scarcity of water resources in India is limiting the production of flooded rice crop. A field experiment was conducted in factorial RBD with sixteen treatment combinations including four rice varieties viz. V1: PR-115, V2: DRRH-3, V3: PAC-837 and V3: PR-121 and four fertility levels viz. F1: control (N0P0K0), F2: N, P2O5, K2O at 90: 45: 22.5 kg ha-1, F3: N, P2O5, K2O at 120:60:30 kg ha-1 and F4: N, P2O5, K2O at 150: 75: 37.5 kg ha-1 replicated thrice. The results revealed that among the different varieties, PAC-837 recorded highest plant height and number of tillers m-2 at all the growth stages. All yield attributes viz. number of effective tillers m-2, number of seeds per panicle, 1000-grain weight, spikelet sterility and grain yield, straw yield and harvest index significantly differed in different varieties and were recorded highest in PAC-837 which were however, statistically at par with DRRH-3 except grain yield and effective tillers m-2. Rice variety PAC-837 recorded highest grain yield of 45.65 q ha-1 and straw yield of 59.98 q ha-1. Among the fertility levels, number of effective tillers m-2 significantly increased up to 120: 60: 30 N-P2O5-K2O kg ha-1 thereafter nonsignificant differences were noticed. The grain and straw yield increased up to 150: 75: 37.5 N-P2O5-K2O kg ha-1 and recoded grain yield of 52.78 q ha-1 and straw yield of 73.85 q ha-1 with application of 150:75:37.5 N-P2O5-K2O kg ha-1. Nutrient application of 150: 75: 37.5 N-P2O5-K2O kg ha-1 recorded highest available N (238.16 kg ha-1), P (16.18 kg ha-1) and K (163.25 kg ha-1) in soil after harvest of the crop. Higher available nitrogen (235.28 kg ha-1), phosphorus (16.38 kg ha-1) and potassium (154.24 kg ha-1) n soil were recorded with PR-121 and lowest available major nutrients were recorded with variety PAC-837. This study would help to introduction and adaptation of new rice variety PAC-837 with application of 150: 75: 37.5 N-P2O5-K2O kg ha-1 under aerobic conditions in Shiwalik foothills region of North-Western Himalayas.

Field experiments were conducted through T. Aman 2003–Boro 2008 at the Bangladesh Rice Research Institute (BRRI), Gazipur Farm with a view to determining the appropriate dose of K fertilizer in soils under double rice cropping system and to find out the alternative source of K for wet land rice cultivation. Four levels of inorganic K (0, 33, 50 & 66 kg K/ha and farmers’ practice from MoP) and one recycling of rice straw 4.5 t/ha (dry basis) were tested. Incorporation of rice straw into soil contributed significantly to grain yield in successive growing seasons comparable with inorganic K fertilizer. In clay- loam soil, K at the rate of 50 kg K/ha should be applied to obtain the maximum yield in both T. Aman and Boro rice seasons. Rice straw may be a potential alternative source of K for sustaining soil K fertility and maximizing rice yield. Agronomic use efficiency of K decreased with increasing K levels. A narrower balance of K was observed when rice straw or a higher dose of inorganic K fertilizer was used. Keywords: K; rice yield; soil K balance; rice straw.

This study was conducted to assess the effect of fertilization and nitrogen fixing (N-fixing) bacterial inoculation on the available nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg), present in the coal mine soil, by growing N-fixing plant species, alder (Alnus sibirica). The study was conducted in a greenhouse of the Forest Science Department, Chungbuk National University, South Korea, during the period of May 2019 to July 2019. A completely randomized design (CRD) comprising of four treatments, including T0—non-fertilized non-inoculation (control), T1—fertilization, T2—bacterial inoculation and T3—fertilization along with bacterial inoculation with three replications were used in the study. The results of the study showed that available N (NH4+-N and NO3−-N) in the coal soil were increased by the applied treatments for alder, as compared to control. Apart from control, difference was also found for increasing ammonium (NH4+-N) between treatments T1 and T3 and for increasing nitrate (NO3−-N) between treatments T1 and T2 and treatments T2 and T3. Available P and K in the soil also increased when NPK fertilizer was applied solely, and together with inoculation to the plants but reduced at other treatments. Therefore, it can be concluded that fertilization and biological N fixation in alder plant can improve the fertility of coal mine soil, and hence, this plant species could be a good option for the reclamation of degraded coal mine soil.

Metabolic Activities

Nitrogen and boron are necessary for the metabolic activities of rice for its growth. With this perspective, a field experiment was conducted in farmer’s field during 2020 at Kuttalam, Mayladuthurai district, Tamilnadu in sandy clay loam(Padugai Series – TypicUstifluvents) to predict the response of rice (Oryza sativa) to different levels of nitrogen(N) and boron (B) application. The treatments consisted of Factor A- Nitrogen levels, 0, 75, 150, 225 kg ha-1 and Factor B- Boron levels 0, 1.5, 3.0 kg ha-1. Fifteen treatments were conducted in a Factorial randomised block (FRBD) design with three replications.  The test crop was rice with a variety ADT 46.    Concerning nitrogen alone, the highest grain (5344 kg ha-1) and straw yield was recorded in N3(225 kg ha-1). Among the boron levels tested, the highest grain (4695 kg ha-1) and straw yield (6509 kg ha-1) was registered in B1 (1.5 kg ha-1) in rice. The highest total nutrient uptake viz., N(88.2 kg ha-1), P(30.5 kg ha-1), K(105.0 kg ha-1) and B(172mg kg-1)  were recorded in N3B1. Among the N alone, the highest total nutrient uptake viz., N(78.1kg ha-1, P(26.3kg ha-1), K (95.8 kg ha-1) and B(156.6 mg kg-1) in N3. Concerning B alone, the highest nutrient uptake viz., N(60.5, kg ha-1) , P(17.8kg ha-1) K(74.9 kg ha-1) and B(112.1mg kg-1) were registered in B1 over other B levels. The highest grain (5631 kg ha-1) was recorded in N3B1 (225 kg N ha-1 and 1.5kg B ha-1) than other interactions. The study concluded that applying nitrogen and boron is required to achieve the maximum yield of rice in sandy clay loam soil.
