The field experiment was carried out during Mar-May 2019 at the Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalai nagar-608002, to study the effect of different planting geometry and sulphur levels in sunflower + greengram intercropping system on the yield, quality, nutrient uptake and post harvest nutrient statusof sunflower. The experiment consisted of twenty treatments and were laid out in factorial randomized block design with two replications. The treatment consisted of Factor A (different plant geometry levels): M1 - sole sunflower (60 x 30 cm), M2 -sunflower (60 x 30 cm) + 1 row of greengram, M3 -sunflower (90 x 30 cm) + 2 rows of greengram, M4 - sunflower (120 x 30 cm) + 3 rows of greengram, M5 - sole greengram and Factor B (sulphur levels): S0 - 0 kg S ha-1, S1 - 20kg S ha-1, S2 - 40kg S ha-1 and S3 - 60kg S ha-1.The results revealedthat yield, quality, nutrient uptake and post harvest nutrient status were significantly influenced by different plant geometry and various sulphur levels. Among the different planting geometry levels tried, sole sunflower (60 x 30 cm) (M1 ) significantly recorded maximum yield, quality, and nutrient uptake of sunflower. With regard to various sulphur levels tried, application of sulphur at 40 kg ha-1(S2 ) significantly recorded maximum yield, quality, and nutrient uptake of sunflower. Interaction between planting geometry and sulphur levels were significant. Among the treatment combinations tried, sole cropping of sunflower (60 x 30 cm) along with application of S at 40 kg ha-1 (M1 S2 )had a spectacular effect on yield, qualityand nutrient uptake of sunflower.The minimum yield, quality and nutrient uptake of sunflower were recorded in sunflower (120 x 30 cm) intercropped with three rows of greengram along with application of S at 0 kg ha-1 (M4 S0 ). With regard to post harvest soil nutrient status, the treatment combination of sunflower (120 x 30 cm) intercropped with three rows

AbstractNutrient uptake by the rice–wheat cropping system (RWCS) is an important indicator of soil fertility and plant nutrient status. The hypothesis of this investigation was that the rate and sources of nutrient application can differentially influence nutrient removal and soil nutrient status in different crop establishment techniques (CETs). Cropping system yield was on par in all the CETs evaluated, however, there were significant changes in soil nutrient availability and microbiological aspects. The system nitrogen (N), phosphorus (P), potassium (K) and zinc (Zn) uptake in aerobic rice system followed by zero tillage wheat (ARS-ZTW) was 15.7–17.6 kg ha−1, 0.7–0.9 kg ha−1, 7–9.8 kg ha−1 and 13.5–23.1 g ha−1 and higher than other CETs. The formulations of Anabaena sp. (CR1) + Providencia sp. (PR3) consortium (MC1) and Anabaena–Pseudomonas biofilm (MC2) recorded significantly higher values of soil chlorophyll and microbial biomass carbon and positively affected cropping system nutrient uptake and soil nutrient balance, illustrating the beneficial effect of microbial inoculation through increased supply of biologically fixed N and solubilised P. Zinc fertilization (5 kg Zn ha−1 through ZnSO4·7H2O as soil application) increased soil DTPA-extractable Zn by 4.025–4.836 g ha–1, with enhancement to the tune of 20–24% after two cropping cycles of RWCS. Our investigation recommends the need for change in the present CETs to ARS–ZTW, along with the use of microbial inoculation as a means of significantly enhancing cropping system nutrient uptake and soil nutrient status improvement.

Background: Cowpea [Vigna unguiculata (L.) Walp] is the most widely cultivated pulse crop of Kerala. Deficiencies of micronutrients viz., Zn and B are a common problem in cowpea. Foliar nutrition is very effective to correct the micronutrient deficiencies in pulses but it is too laborious. Seed pelleting and priming are two simple cost-effective methods to overcome the micronutrient deficiencies. The present study aimed to study the effect of seed invigouration with zinc sulphate and borax and to evaluate its effect along with Trichoderma viride on nutrient uptake and soil nutrient status of grain cowpea.Methods: The experiment was conducted at Coconut Research Station, Balaramapuram, Thiruvananthapuram, Kerala. The experiment was conducted in RBD with 8 seed invigouration treatments and a control during Rabi 2018.Result: Seed invigouration treatments had significant effect on nutrient uptake and nutrient availability. Seeds primed in ZnSO4 0.05 per cent for 4h recorded the highest NPK uptake by crop, the highest soil organic carbon content, available N and Zn status. Zinc uptake by crop and available soil K status were recorded the highest in seed primed in ZnSO4 0.05 per cent for 4h + Trichoderma viride seed treatment 10 g kg-1 seed. Boron uptake by crop and available soil B and P status were recorded the highest in seeds pelleted with borax 100 mg kg-1 seed. Hence it can be concluded that seed primed in ZnSO4 with 0.05 per cent for 4 h improved the Zn availability and uptake and seed pelleting with borax 100 mg kg-1 improved the B availability and uptake of grain cowpea.
